The traffic police terminal sends an http front-end equipment control request to the data server based on an http protocol, when the request is sent, the front-end equipment in a monitoring place is controlled to rotate, adjust the focal length, reset and the like, so that the monitored video image information quantity is more, more accurate judgment and treatment can be carried out on illegal behaviors, a sender can also be a developer with control authority and used for controlling and adjusting the front-end equipment, relevant parameters of the front-end equipment are optimized according to the content of images shot by a front-end camera in the adjusting process, and the front-end equipment is correspondingly debugged based on relevant feedback in the controlling process, so that the optimal shooting performance is obtained. The http front-end device control request can be sent through a video monitoring platform developed independently, or can be directly sent through a web browser and received by a data server. The request under the http protocol is a one-way channel request from the traffic police terminal to the data server.

The http front-end device control request carries a target device identifier and a first format operation instruction, wherein the target device identifier comprises an ID of a target camera and/or an ID of a target holder, the first format operation instruction is an English format operation instruction under an http protocol, and the English format operation instruction is popular and easy to understand relative to other types of operation instructions and has low requirement on a request initiator.

After receiving a trigger instruction for controlling the front-end equipment, the traffic police terminal displays a control selection page comprising a front-end equipment selection control and an operation instruction selection control, and then performs corresponding selection operation on the control selection page to determine which front-end equipment in a monitoring place is to be controlled and what type of control is specifically performed on the front-end equipment. When the front-end equipment selection control is triggered, a catalog of all registered front-end equipment is generated, then, one or some front-end equipment can be selected as target equipment, and the front-end equipment catalog can set the traffic police terminal initiating the request or the front-end equipment requesting selection last time as default target equipment. When the operation instruction selection control is triggered, an operation instruction directory is generated, the operation instruction directory comprises a plurality of types of operation instructions, after a selection operation is performed on a certain operation instruction, a sub-instruction directory corresponding to the operation instruction is displayed, one operation instruction can be selected each time when the selection operation is performed, a plurality of operation sub-instructions corresponding to the operation instruction can be simultaneously selected, the operation instruction and the corresponding operation sub-instruction form a first format operation instruction, and the first format operation instruction which is requested to be selected last time in the operation instruction directory can be set as a default operation instruction.

And after the corresponding selection operation is carried out on the control selection page, generating an http front-end equipment control request conforming to the http protocol according to the target equipment identification of the target equipment and the first format operation instruction.

S204: and determining the target equipment and a target 5G base station corresponding to the target equipment according to the target equipment identifier, and determining long connection with the target 5G base station.

In a 5G scenario, all front-end devices in a certain area are correspondingly connected with a 5G base station, a one-to-many connection relationship is formed between the 5G base station and the front-end devices, and the connection relationships are stored in a data server, so that a target device corresponding to a target device identifier can be determined according to the target device identifier, which 5G base station the target device is connected with can be further determined, and the 5G base station is used as the target 5G base station. And for all 5G base stations, long connection is established between the data server, and after the target 5G base station is determined, the long connection between the data server and the target 5G base station can be found.

And after the long connection is determined, sending an sip front-end equipment control request to the target 5G base station through the long connection. The long connection between the data server and the target 5G base station is transmitted based on a 5G protocol, and the sip front-end equipment control request is a request under the sip protocol, so that during transmission, the sip front-end equipment control request is firstly encapsulated into a first encapsulation packet and then is transmitted to the target 5G base station through the long connection, and the target 5G base station then unpacks the first encapsulation packet into the sip front-end equipment control request.

The target 5G base station is connected with the front-end equipment by adopting an sip protocol, and each front-end equipment is connected by adopting an sip dedicated line so as to ensure the safety of data, so that the target 5G base station controls the target 5G base station to send a sip front-end equipment control request to the target equipment through the sip dedicated line based on the sip protocol after receiving the sip front-end equipment control request.

And after receiving the request, the target equipment executes corresponding control operation according to the specific content of the request. When the request relates to adjustment of focus adjustment, screen enlargement and reduction, etc., the corresponding operation is performed by the front-end camera, and when the request relates to adjustment of rotation, preset position, etc., the corresponding operation is performed by the front-end pan/tilt head. The traffic police terminal sends different types of control requests, so that the front-end equipment executes different control operations, multi-directional video data can be acquired, the accuracy of illegal data identification is improved, and the video acquisition requirements under different scenes are met.

According to the method, the front-end equipment control method provided by the application comprises the steps of firstly receiving an http front-end equipment control request sent by a traffic police terminal on a control selection page based on an http protocol, wherein the http front-end equipment control request carries a target equipment identifier and a first format operation instruction; then, according to the first format operation instruction and a preset format conversion table, obtaining a second format operation instruction corresponding to the first format operation instruction; generating a sip front-end device control request according to the target device identification and the second format operation instruction; and finally, sending the sip front-end equipment control request to the target equipment through the target 5G base station based on the sip protocol so as to enable the target equipment to respond and execute corresponding control operation. The method and the system send out the http control request based on the http protocol and convert the http control request into the sip control request which can be identified by the front-end equipment, and can directly select the corresponding target equipment and the first format operation instruction according to the selection operation when the request is sent out on the control selection page, so that the operation is simple, the traffic police terminal can complete the whole control process only on a web browser or a platform, and the method and the system are simple and easy to operate; in addition, the information transmission is carried out through the 5G base station, the speed is high, and the control efficiency of the front-end equipment is improved.

As shown in fig. 3, a control front-end device control 100 is arranged on a platform interface of the traffic police terminal, and when the traffic police terminal wants to control the front-end device at a certain intersection at a certain time, the traffic police terminal clicks the control front-end device control 100, receives a trigger instruction for controlling the front-end device, and displays a control selection page including a front-end device selection control 200 and an operation instruction selection control 300. The control front-end equipment control 100 and the other two controls can be arranged on different pages, namely, the control selection page can be a page generated by clicking the control front-end equipment control 100 on the other page of the traffic police terminal; the control front-end device control 100 and the other two controls may also be set on the same page, when the control front-end device control 100 is not clicked, the other two controls are not displayed, and after the control front-end device control 100 is clicked, the page serves as a control selection page to display the front-end device selection control 200 and the operation instruction selection control 300.

After the control selection page clicks the front-end device selection control 200, the control selection page generates a front-end device directory 201 according to a trigger operation for the front-end device selection control 200, all front-end devices registered in the intelligent transportation system can be displayed in the front-end device directory 201, and then a corresponding selection operation is performed in the front-end device directory 201 to determine which front-end device is controlled. When performing the selecting operation, one or more front-end devices may be selected from the front-end device directory 201 as target devices, wherein the front-end device that has been requested to be selected last time or the front-end device that has been requested to be selected with a higher frequency may be set as a default target device. When there are many front-end devices in the front-end device directory 201, a search or screening function may be set, and the search range is narrowed according to information such as keywords, so that a target device to be selected can be quickly searched.

Similarly, after the control selection page clicks the operation instruction selection control 300, the control selection page generates an operation instruction directory 301 according to the trigger operation for the operation instruction selection control 300, and all the operation instructions that can be executed by the front-end device can be displayed in the operation instruction directory. The operation instruction list 301 first displays various operation commands, such as a rotation operation, a lens control operation, a termination operation, a preset operation, a locking operation, and the like, and selects one of the various operation commands when performing a selection operation, and then displays an operation sub-command corresponding to the operation command after selecting the operation command, for example, when selecting the rotation operation, the corresponding operation sub-command may include a movement direction, a movement speed, and the like. In addition, for operation subcommands of which the movement speed and the like relate to specific numerical values, corresponding parameter input boxes are generated after selection, and the specific numerical values can be input in the corresponding parameter input boxes according to requirements. The first format operation command is generated according to the operation command and the selection operation of each operation sub command.

After the front-end device selection control 200 and the operation instruction selection control 300 are executed with corresponding selection operations, and the click determination 400, an http front-end device control request conforming to an http protocol is generated according to the target device identifier of the target device and the first format operation instruction.

As shown in fig. 4, the framework of the front-end device control is divided into several modules, an http front-end device control request 21 sent by the traffic police terminal is received by the http gateway 22, then the request parser 23 parses and classifies a first format operation instruction recognizable by the http protocol in the http front-end device control request 21, and then the operation instruction generator 24 converts the first format operation instruction to generate a second format operation instruction recognizable by the sip protocol. The sip request generator 25 generates an sip front-end device control request corresponding to the http front-end device control request 21 according to the target device identifier and the second format operation instruction carried in the http front-end device control request 21, and finally sends the sip front-end device control request to the target 5G base station 27 through the sip gateway 26, and then the sip front-end device control request is sent to the target device 28 through the target 5G base station 27, and the target device 28 responds and executes a corresponding control operation. Through the steps, the traffic police terminal completes various operation adjustments on the target equipment of the monitoring site, so that more video information amount can be obtained, and the accuracy of illegal data identification is improved.

Fig. 5 is a logic diagram of the first format operation command converted into the second format operation command by the operation command generator 24, and fig. 6 is a logic diagram of the sip request generator 25 generating the sip front-end device control request. The front-end device control method of the present application is further described below with reference to fig. 4 to 6.

The http front-end device control request 21 sent by the traffic police terminal is sent to the request parser 23 through the http gateway, and the request parser 23 parses the target device identifier and the first format operation instruction 30. The first format operation instruction 30 may include a rotation operation, a lens control operation, a termination operation, a preset bit operation, a lock operation, and the like, according to the type of the control request. Taking the http front-end device control request 21 sent by the traffic police terminal as an example, the contents include "CmdType ═ deviceControl & sessionId ═ test & platf ormId ═ 42010500002006533266& deviceId ═ 42010502001325871820& type ═ ptz & direct ═ u & speed ═ 120", and after the analysis, the description of various parameters is shown in table 1:

TABLE 1

The "type ═ ptz" indicates that the first format operation command 30 carried by the http front-end device control request 21 is a rotation operation command, "direct ═ u" indicates that the operation sub-command corresponding to the rotation operation command is an upward rotation, and "speed ═ 120" indicates that the speed of the upward rotation is 120 degrees per second. When the first format operation instruction 30 is a lens control operation instruction, the corresponding command type and assignment are aperture control "type ═ alert", zoom control "type ═ zoom", or focus control "type ═ focus", respectively. When the first format operation instruction 30 is a termination operation instruction, the corresponding command type and assignment are termination rotation "type ═ stopPtz", termination focus "type ═ stopFocus", termination aperture control "type ═ stoptask" or termination variable magnification control "type ═ stopZoom", respectively. When the first format operation instruction 30 is a preset bit operation instruction, the corresponding command type and assignment are a preset bit "type ═ preset", a call preset bit "type ═ presetCall", a delete preset bit "type ═ presetDelete", and the like, respectively. When the first format operation instruction 30 is a lock operation instruction, the corresponding command type and assignment may be any one of the command types and assignments described above, and corresponding lock control is performed through an operation sub-command following the operation command.

After the first format operation instruction 30 is obtained through analysis, the operation instruction generator 24 obtains a second format operation instruction 40 corresponding to the first format operation instruction 30 according to the first format operation instruction 30 and a preset format conversion table, where the first format operation instruction 30 is an english operation instruction, and the second format operation instruction 40 is a 16-system hardware operation instruction. In one embodiment, the steps specifically include: an operation terminal 41 for generating a second format operation instruction 40 according to the operation command 31 corresponding to the first format operation instruction 30; generating an operation code of the second format operation instruction 40 according to the operation sub-command corresponding to the operation command 31; generating a check bit 43 of the second format operation instruction 40 according to the operation terminal 41 and the operation code; the operation terminal 41, the operation code and the check bit 43 are combined to generate the second format operation instruction 40.

The assignment value of the operation command 31 is ptz, and the operation command is converted into the operation header 41 of the second format operation instruction 40 according to a preset format conversion table, as the 1 st bit of the second format operation instruction 40, and the specific value is 0xA 5.

The operation command 31 corresponds to a plurality of operation subcommands, and the number and type of the operation subcommands are different according to the different complexity of the request content, so that the more complicated the request content is, the more the number and type of the corresponding operation subcommands are, and the more accurate the control of the front-end device is. Each operation subcommand corresponds to a one-bit opcode that translates into a second format operation instruction 40.

In one embodiment, the step of generating the operation code comprises: classifying the plurality of operation subcommands corresponding to the operation command 31, determining the positions of the operation codes corresponding to the various operation subcommands in the second format operation instruction 40 according to a preset sequence, and sequentially generating the operation code corresponding to each operation subcommand. As shown in fig. 5, taking four types of operation subcommands as an example, the various types of operation subcommands are sorted in the front-back order in the http front-end device control request 21, and sequentially include a first operation subcommand 321, a second operation subcommand 322, a third operation subcommand 323, and a fourth operation subcommand 324. The first operation sub-command 321 is used to define the rotation direction of the target device, is correspondingly converted into the first operation code 421, is located at the 2 nd bit of the second format operation instruction 40, and the value of the 16 th digit of the first operation code 421 is different according to the rotation direction. The second operation subcommand 322 is used to define the vertical speed and the horizontal speed of the target device, and is correspondingly converted into the second operation code 422, which is located at the 3 rd bit of the second format operation instruction 40. And in turn, the third operation subcommand 323 is converted into the third operation code 423 located at the 4 th bit of the second format operation instruction 40, the fourth operation subcommand 324 is converted into the fourth operation code 424 located at the 5 th bit of the second format operation instruction 40, until all the operation subcommands corresponding to the operation command 31 are converted. Then, a check bit 43 is added after the operation terminal 41 and the operation code, and the calculation formula of the check bit is as follows: (upper 4 bits of byte 1 + lower 4 bits of byte 1 + upper 4 bits of byte 2)% 16, where byte 1 is the 1 st bit of the second format operation instruction 40 and byte 2 is the 2 nd bit of the second format operation instruction 40. And combining the operation terminal 41, the operation code and the check bit to generate a second format operation instruction 40.

In an embodiment, the step of generating the second format operation instruction 40 includes: after the first format operation instruction 30 is obtained, a preset format conversion table is searched to obtain an operation terminal 41 corresponding to the operation command 31 of the first format operation instruction 30 and an operation code corresponding to the operation sub-command, a check bit 43 corresponding to the first format operation instruction 30 is obtained through calculation, and a second format operation instruction 40 is generated according to a search result and a calculation result. For the operation command 31 and each operation sub-command of the first format operation command 30, a unique operation terminal or operation code is corresponding to the operation command in a preset format conversion table, the format conversion table may be stored in the data server in advance, after the first format operation command 30 is analyzed and enters the operation command generator 24, the operation command generator 24 performs corresponding search from the format conversion table, then performs format conversion, and then calculates to obtain a corresponding check bit to detect whether the data is in error in the conversion process, and finally generates the second format operation command 40 according to the search result and the calculation result.

After generating the second format operating instructions 40, the sip request generator 25 generates the sip front-end device control request 80 based on the target device identification and the second format operating instructions 40. In one embodiment, the steps specifically include: generating a sip request header 60 according to the target device identifier; generating a sip request message body 70 according to the second format operation instruction 40; the sip request header 60 and sip request message body 70 are combined to generate the sip frontend device control request 80. The data server includes a front-end device storage unit in which access addresses of a plurality of front-end devices registered in the intelligent transportation system and other related information are stored, and the sip request generator 25 acquires a target device access address 50 from the front-end device address storage unit based on a target device identification, and then generates a sip request header 60 based on the address. Then, the second format operation instruction 40 is processed to generate an sip request message body 70, and finally, the sip request header 60 and the sip request message body 70 are combined to generate an sip front-end device control request 80.

After the sip frontend device control request 80 is generated, it is sent to the sip gateway 26, and the sip gateway 26 sends the sip frontend device control request 80 to the target 5G base station 27. At this time, the target device 28 corresponding to the identifier is determined according to the target device identifier carried in the sip front-end device control request 80, and further, which 5G base station the target device 28 is connected to is determined, and the 5G base station is used as the target 5G base station 27. For all 5G base stations, long connections have been established with the data server, and after the target 5G base station 27 is determined, the long connection between the data server and the target 5G base station 27 can be found, and then the sip front-end device control request 80 is sent to the target 5G base station 27 through the long connection.

In one embodiment, the specific step of sending the sip front-end device control request 80 to the target 5G base station 27 includes: encapsulating the sip frontend device control request 80 into a first encapsulation packet; the first encapsulated packet is sent over the long connection to the target 5G base station 27. Since the long connection between the data server and the target 5G base station 27 is based on 5G protocol transmission, and the sip front-end device control request 80 is a request under the sip protocol, the sip front-end device control request 80 is encapsulated into a first encapsulation packet, and then is sent to the target 5G base station 27 through the long connection, and the target 5G base station 27 then unpacks the first encapsulation packet into the sip front-end device control request 80.

In one embodiment, the specific step of sending the sip front-end device control request 80 to the target 5G base station 27 further includes: acquiring a connection period between a target 5G base station 27 and target equipment 28; in the connection period, the sip frontend device control request 80 is sent to the target 5G base station 27 through the long connection to control the target 5G base station 27 to send the sip frontend device control request 80 to the target device 28 through the sip dedicated line based on the sip protocol. The target 5G base station 27 and all the front-end devices in the connection range form a one-to-many relationship, for each front-end device, the target 5G base station 27 has a connection channel corresponding to the front-end device, but the connection channels between the target 5G base station 27 and the front-end devices are not connected at all times, but are sequentially opened and closed according to a certain sequence, so for each front-end device, there is a connection period corresponding to the connection period, and only in the connection period, the front-end device and the target 5G base station 27 can realize communication, so that it is necessary to first obtain the connection period between the target 5G base station 27 and the target device 28, and then in the connection period, control the target 5G base station 27 to send the sip front-end device control request 80 to the target device 28.

The target 5G base station 27 and the front-end devices are connected by using an sip protocol, and for each front-end device, an sip dedicated line is used for connection to ensure the security of data, so that after the target 5G base station 27 receives the sip front-end device control request 80, the data server controls the target 5G base station 27 to send the sip front-end device control request 80 to the target device 28 through the sip dedicated line based on the sip protocol.

The data server sends an sip frontend device control request 80 to the target device 28 through the target 5G base station 27 based on the sip protocol based on the target device identification and the target device access address obtained from the frontend device address storage unit. After receiving the request, the target device 28 determines whether the front-end pan/tilt head or the front-end camera performs a corresponding control operation according to the specific content of the request. When the request relates to the focal length adjustment of the lens and the zoom-in and zoom-out adjustment of the picture, the front-end camera executes corresponding operation, and when the request relates to the adjustment of rotation, preset positions and the like, the front-end holder executes corresponding operation. The traffic police terminal sends different types of control requests, so that the front-end equipment executes different control operations, multi-azimuth video data can be acquired, the accuracy of illegal data identification is improved, and the video acquisition requirements under different scenes are met.

In the above embodiment, the http front-end device control request 21 sent by the traffic police terminal is a no-response request, that is, after the request is sent to the target device 28, the target device 28 directly responds and executes the corresponding control operation, without returning a control response to the traffic police terminal. However, the present application is not limited to this, and the traffic police terminal may also make the sent http front-end device control request 21 a request with response, and at this time, after sending the sip front-end device control request 80 to the target device 28 based on the sip protocol, the method further includes the following steps: receiving a control response generated after the target device 28 returned by the target 5G base station 27 through the long connection performs a control operation; and returning a control response to the traffic police terminal based on the http protocol.

When the http front-end device control request 21 is a response request, a message synchronizer (not shown in the figure) is further arranged in the data server, and after the sip request generator 25 generates the sip front-end device control request 80, the message synchronizer synchronizes the http front-end device control request 21 and the sip front-end device control request 80 and then sends the synchronized http front-end device control request and the sip front-end device control request 80 to the sip gateway 26. Specifically, in the message synchronizer, generating an http state identifier corresponding to the http front-end device control request 21, an sip state identifier corresponding to the sip front-end device control request 80, and synchronizing the identification content of the http state identifier and the sip state identifier in real time, wherein the identification content comprises a control request overtime state and a control request completion state, then based on the sip protocol, sending the sip front-end device control request 80 to the target device corresponding to the target device identifier through the target 5G base station 27, receiving the sip front-end device control response returned by the target device based on the sip protocol through the target 5G base station 27, synchronously updating the identification content of the sip state identifier and the http state identifier according to the content of the sip front-end device control response, and generating the http front-end device control response corresponding to the http state identifier when the identification content of the http state identifier meets the preset condition, and finally returning an http front-end equipment control response to the traffic police terminal based on the http protocol.

After the identification content of the sip state identification and the http state identification is updated, if the identification content of the http state identification meets a preset condition, the data server generates a corresponding http front-end device control response, and the response content of the http front-end device control response is the same as the response content of the sip front-end device control response. And when the identification content of the http state identification is one of the control request and the control request, generating an http front-end device control response corresponding to the http state identification.

And after generating the http front-end equipment control response, returning the http front-end equipment control response to the traffic police terminal, and determining whether a new video picture shot after the front-end equipment executes the control operation can be watched by the traffic police terminal based on the condition that the control request is completed or exceeds the time limit in the received control response. When the control request is finished, the traffic police terminal can obtain a new video picture shot by the target equipment so as to obtain more information quantity of the monitoring site, and when the control request is overtime, the traffic police terminal can send the control request again or analyze the reason of the overtime, find the reason of the overtime and send the control request after the reason is solved. The whole control request and response receiving process of the traffic police terminal can be completed only on a web browser or a platform, the operation is simple and easy, and the control efficiency of front-end equipment is improved.

As shown in fig. 7, in an initial stage, a picture shot by a target device and seen in a video area 500 of a picture display page shot by a front-end device of a traffic police terminal includes a sidewalk, pedestrians and vehicles, wherein only a part of the sidewalk can be shot due to the visual angle limitation of the target device, when information of another part of the sidewalk, surrounding pedestrians and vehicles is desired to be obtained, the traffic police terminal sends a http front-end device control request based on an http protocol, controls the target device to rotate, and makes a target camera rotate upward, at this time, the picture obtained in the video area 500 is as shown in fig. 8, the pictures in fig. 7 and fig. 8 are combined, the shot range is wider, whether a vehicle or a pedestrian has a traffic violation in the current scene can be completely seen, and thus the identification capability of the violation data is improved. In addition, when illegal vehicles or pedestrians need to be further tracked and identified, the traffic police terminal can send out an http front-end device control request again, corresponding control operations such as focal length adjustment and picture amplification are carried out, the whole process can be completed only on a webpage browser or a platform, the time from the request initiation to the target device execution operation is short, and great convenience is brought to locking and tracking of illegal objects.
