The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

In the embodiment of the description, the terminal device obtains the instruction cached by the control end at the server end by receiving the request of obtaining the instruction from the terminal device within the preset time, and the terminal device executes the instruction, so that the purpose of controlling the terminal device is achieved, and the control end can better control the terminal device. Based on the received request from the control end, the instruction for establishing the long connection can be put into an instruction list to be executed, so that the long connection is established between the service end and the terminal equipment, the long connection is established between the service end and the control end, the instruction sent by the control end can be forwarded to the terminal equipment in real time, and the terminal equipment responds to the instruction of the control end in real time.
Corresponding to the above embodiments, fig. 2 is a schematic flow chart of a remote control method for a terminal device provided in the second embodiment of this specification.
The present embodiment may be implemented by the server side, and specifically includes:
step S201, in a preset time, a server receives a request message sent by a terminal device to acquire an instruction to be executed, where the request message includes a device identifier of the terminal device.
In step S201 of the embodiment of the present specification, the preset time may be dynamically set according to specific requirements. And the server provides an interface for modifying the instruction list to be executed so that the control end can call the interface and dynamically modify the instruction list to be executed. The modification includes addition, reduction or change, and the instruction to be executed of each terminal device may be multiple.
Step S202, according to the request message, the server determines the device identifier of the terminal device, and queries a pre-cached instruction list to be executed based on the device identifier, wherein the device identifier of the terminal device is stored in correspondence with the instruction list to be executed of the terminal device.
In step S202 in this embodiment of the present specification, the server may store the device identifier and the instruction list to be executed corresponding to the device identifier in a database, so as to prevent the server from losing data when the server is powered off. The instruction list to be executed stores a plurality of instructions to be executed, and the plurality of instructions to be executed may be instructions to be executed that are returned to a plurality of terminal devices, or may be instructions to be executed that are returned to one terminal device.
Step S203, the server returns the to-be-executed instruction corresponding to the identifier of the terminal device to the terminal device, so that the terminal device executes the to-be-executed instruction.
In step S203 of this specification embodiment, the instruction to be executed by the terminal device is an instruction that is cached in the server by the control end in advance, and only when the terminal device sends request information for acquiring the instruction to be executed to the server, the server will return the instruction to be executed corresponding to the identifier of the terminal device to the terminal device, and the terminal device executes the instruction to be executed after acquiring the instruction to be executed. The instruction to be executed at least comprises one or more of establishing long connection, disconnecting long connection, obtaining terminal equipment information, uploading logs, uploading coordinates and upgrading versions.
In the above step, for scenario one, an operator operates the control end to modify the to-be-executed instruction list, where the to-be-executed instruction list may include multiple instructions, and the server receives the modified to-be-executed instruction list sent by the control end. And in the set time, the terminal equipment requests a to-be-executed instruction list, the server side inquires whether an instruction containing the identifier of the terminal equipment exists, and if so, the server side returns a corresponding to-be-executed instruction list to the terminal equipment.
Step S204, based on the request received from the control end, the service end puts the long connection establishment instruction into the instruction list to be executed, so that the service end establishes long connection with the terminal device, and receives the long connection establishment request from the control end, so that the service end establishes long connection with the control end.
In step S204 in this embodiment of the present description, when the control end needs the terminal device to execute the issued instruction in real time, it is necessary to establish a long connection between the service end and the terminal device, and establish a long connection between the service end and the control end. The server side puts the instruction for establishing long connection into the instruction list to be executed, so that the terminal device and the server side establish long connection. It should be noted that the time for the server to establish the long connection with the control end may occur before the server establishes the long connection with the terminal device, or may occur after the server establishes the long connection with the terminal device, which is not limited in this specification.
In step S204 in this embodiment of the present description, the server receives a request for establishing a long connection from the control end, so that after the server establishes a long connection with the control end, the server may further store an identifier of the terminal device in a first long connection maintenance list; storing the identifier of the control end into a second long connection maintenance list; and the first long connection maintenance list and the second long connection maintenance list are correspondingly stored.
Step S205, the server receives the information sent by the control end, and obtains the identifier of the terminal device and the instruction to be executed corresponding to the identifier of the terminal device according to the information.
Step S206, searching the long connection maintenance list according to the obtained identifier of the terminal equipment, and sending the instruction to be executed corresponding to the identifier of the terminal equipment to the terminal equipment through long connection so that the terminal equipment can execute the instruction to be executed corresponding to the identifier of the terminal equipment in real time.
In step S206 in this embodiment of the present description, in a state that a long connection has been established between a terminal device and a server, and a long connection has been established between the server and a control terminal, the control terminal sends a to-be-executed instruction corresponding to an identifier of the terminal device and the identifier of the terminal device to the server, the server searches for a long connection maintenance list, and if the identifier of the terminal device exists in the long connection maintenance list, the server forwards the to-be-executed instruction to the terminal device corresponding to the identifier of the terminal device in a long connection manner, so that the terminal device executes the to-be-executed instruction in real time.
Step S204-step S206, aiming at the second scene, the operator operates the control end, adds the instruction for establishing the long connection into the instruction list to be executed, and the server end receives the instruction for establishing the long connection with the terminal equipment, which is sent by the control end. Within a set time, the terminal equipment requests a list of instructions to be executed, the server inquires an instruction of an identifier of the terminal equipment, and returns an instruction for establishing long connection to the terminal equipment, so that the long connection between the control terminal and the server is completed, and the long connection between the server and the terminal equipment is established.
The server receives a request for establishing long connection from the control terminal, so that after the server establishes long connection with the control terminal, the method further comprises:
and the server receives a first protocol sent by the control terminal so as to judge whether the server establishes long connection with the terminal equipment or not through the first protocol.
The server receives a request for establishing long connection from the control terminal, so that after the server establishes long connection with the control terminal, the method further comprises:
and the server receives a second protocol sent by the plurality of control terminals, so that the plurality of control terminals monitor the terminal equipment through the second protocol. The terminal device and the server have established long connection, and the control end monitoring the terminal device may be the control end establishing long connection with the server or the control end not establishing long connection with the server. In addition, the control end can also monitor a plurality of terminal devices establishing long connection. When the terminal device that establishes the long connection sends data through the long connection, the data is forwarded to all control terminals that monitor the terminal device.
When the instruction to be executed corresponding to the identifier of the terminal equipment is to disconnect long connection; after the instruction to be executed corresponding to the identifier of the terminal device is sent to the terminal device through the long connection, the method further includes:
the server side disconnects with the terminal equipment, the server side disconnects with the control side, the identifier of the terminal equipment in the first long connection maintenance list and the identifier of the control side in the second long connection maintenance list are deleted, and the monitoring relation of the plurality of control sides to the terminal equipment is relieved.
The server receives a request for establishing long connection from the control terminal, so that after the server establishes long connection with the control terminal, the method further comprises:
the server receives a third protocol sent by the control end, so that the transmission mode of the instruction to be executed corresponding to the identifier of the terminal equipment is changed into a mode that the request information for acquiring the instruction to be executed is sent to the server through the terminal equipment within a preset time, and the server returns the instruction to be executed corresponding to the identifier of the terminal equipment to the terminal equipment after receiving the request information for acquiring the instruction to be executed sent by the terminal equipment. It should be noted that, in a state where the terminal device establishes the long connection with the server and the server establishes the long connection with the control end, the instruction to be executed may not be directly forwarded through the third protocol, but the terminal device is required to send request information for acquiring the instruction to be executed within a preset time.
It should be noted that the first protocol, the second protocol, and the third protocol may be control codes sent by the control end to the service end, and corresponding instructions are executed through the service end.
It should be noted that in this embodiment of the present specification, the control end includes one or more of a PC end browser, a PC end control program, third-party software that can perform communication at the PC end, a mobile end browser, a mobile end APP, or an applet.
It should be noted that, in this embodiment of the present specification, the control end may send different device identifiers and instructions to be executed to the service end, and the service end may select different terminal devices to forward according to the device identifiers, so that single-station communication and group broadcast of the terminal devices by the control end may be implemented.
One control method of the existing control end to the terminal is as follows: the server caches the control end instruction and waits for the active request of the terminal equipment, the transmission of the control end instruction depends on the active request of the terminal equipment, and the time of the active request of the terminal equipment is uncertain, so that the task with higher real-time requirement cannot be met. Another existing control method for a terminal by a control end is as follows: the way that the terminal equipment establishes long connection with the server and the server forwards the control end instruction means that the server needs to maintain the long connection with the control end and the terminal equipment in real time, and the server resources are wasted and certain pressure is caused on the terminal equipment under the condition that real-time communication is not needed. Compared with the prior art, the embodiment of the specification requests the terminal equipment to acquire the instruction at regular time under the conventional condition, and the control end can modify, add or delete the instruction through the server-end interface, so that non-real-time control is realized; for tasks with higher real-time requirements, the real-time control of a control end on a plurality of devices is realized by dynamically establishing long connection and forwarding at a server end; when the communication is finished, the long connection is disconnected, so that the resource waste caused by maintaining the long connection is avoided; the group broadcast and the single real-time communication to the terminal equipment can be selected according to the requirements, and the reduction of the power consumption and the network flow of the terminal equipment is facilitated.
In the embodiment of the description, the terminal device obtains the instruction cached by the control end at the server end by receiving the request of obtaining the instruction from the terminal device within the preset time, and the terminal device executes the instruction, so that the purpose of controlling the terminal device is achieved, and the control end can better control the terminal device. Based on the received request from the control end, the instruction for establishing the long connection can be put into an instruction list to be executed, so that the long connection is established between the service end and the terminal equipment, the long connection is established between the service end and the control end, the instruction sent by the control end can be forwarded to the terminal equipment in real time, and the terminal equipment responds to the instruction of the control end in real time.
Corresponding to the above embodiment, fig. 3 is a schematic structural diagram of a remote control device of a terminal device provided in the third embodiment of this specification, and specifically includes: a receiving unit 1, a determining unit 2 and an executing unit 3.
The receiving unit 1 is used for the server side to receive a request message for acquiring a command to be executed, which is sent by the terminal device, within a preset time; the request message includes a device identifier of the terminal device.
The determining unit 2 is configured to determine a device identifier of the terminal device according to the request message, and query a pre-cached instruction list to be executed based on the device identifier, where the device identifier of the terminal device is stored in correspondence with the instruction list to be executed by the terminal device; and returning the instruction to be executed corresponding to the identifier of the terminal equipment to the terminal equipment so as to facilitate the terminal equipment to execute the instruction to be executed.
The execution unit 3 is configured to, based on receiving a request from the control end, put a long connection establishment instruction into the instruction list to be executed, so that the service end establishes a long connection with the terminal device; and receiving a request for establishing long connection from the control terminal, so that the service terminal and the control terminal establish long connection.
In the embodiment of the description, the terminal device obtains the instruction cached by the control end at the server end by receiving the request of obtaining the instruction from the terminal device within the preset time, and the terminal device executes the instruction, so that the purpose of controlling the terminal device is achieved, and the control end can better control the terminal device. Based on the received request from the control end, the instruction for establishing the long connection can be put into the instruction list to be executed, so that the long connection is established between the service end and the terminal equipment, the long connection is established between the service end and the control end, the instruction issued by the control end can be forwarded to the terminal equipment in real time, and the terminal equipment responds to the instruction of the control end in real time.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.
As will be appreciated by one skilled in the art, embodiments of the present invention may be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
The present invention is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
