Description

Linkage method, device and system for sensing device

This application claims the priority of the Chinese Patent Application filed on March 27, 2017, the Chinese Patent Office, Application No. 201710187470.7, entitled "A Method, Apparatus and System for Sensing Devices", the entire contents of which are incorporated by reference. Combined in this application.

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, device, and system for linkage of sensing devices.

Background technique

The Internet of Things (IoT) refers to a huge network of various sensing devices, such as radio frequency identification devices, infrared sensors, global positioning devices, laser scanners, etc., combined with the Internet.

As shown in Figure 1, it is a schematic diagram of a possible design architecture of the Internet of Things. Wherein, each sensing device 11 is configured to collect the sensed data (eg, temperature data collected by the temperature sensor) and/or execute a control command (eg, a smart door lock to execute a door open command). Each sensing device 11 can transmit the collected data to the gateway 12, which transmits the data to the IoT cloud platform 13. The IoT cloud platform 13 can perform unified decisions based on the data reported by the sensing device 11, for example, managing the connection relationship between the sensing devices 11 and the like. The user can send a management instruction for managing the sensing device 11 to the IoT cloud platform 13 through the IoT application 14, for example, the user triggers a door opening command on the IoT application 14, and the IoT application 14 sends the door opening command to the IoT cloud platform 13, The IoT cloud platform 13 sends the door opening command to the corresponding sensing device 11 through the gateway 12, and finally the sensing device 11 executes the door opening command.

In the IoT, there may be a linkage strategy between the sensing devices 11. For example, when the door (sensing device A) is turned on, the illumination lamp (sensing device B) is required to be automatically turned on. In this regard, as shown in FIG. 1, a rule engine 15 may be disposed in the gateway 12, and the rule engine 15 performs a linkage decision according to the stored linkage policy. For example, after the sensing device A sends the data of the device status to the gateway 12, the rule engine 15 in the gateway 12 searches for the corresponding linkage policy according to the data of the device state of the sensing device A, thereby generating a decision for controlling the sensing device B. The instruction sends the decision instruction to the sensing device B, and the sensing device B executes the decision instruction to complete the linkage strategy between the sensing device A and the sensing device B.

It can be seen that each time the linkage policy between the two sensing devices 11 is executed, the gateway 12 needs to be the other sensing device according to the data of the device state of one of the sensing devices 11 and the corresponding linkage policy. 11 Generate corresponding decision instructions. Then, when the number of the sensing devices 11 is large, the implementation process of the linkage policy requires the gateway 12 to have strong computing performance and maintain the online state at the moment, then, once the computing performance of the gateway 12 is not up to standard, or the gateway 12 is powered off, For example, the gateway 12 is disposed in an environment such as a forest lacking a stable external power source, and the linkage scenario between all the sensing devices 11 will be invalid.

detailed description

In the following, the terms "first" and "second" are used for descriptive purposes only, and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, features defining "first" and "second" may include one or more of the features either explicitly or implicitly. In the description of the embodiments of the present application, "multiple" means two or more unless otherwise stated.

The embodiment of the present application provides a linkage method of a sensing device, which can be applied to the linkage system 100 shown in FIG. 2. The linkage system 100 includes at least one gateway 21 and at least one sensing device 22 coupled to each gateway 21.

The sensing device 22 is configured to sense the measured information, and can convert the sensed information into an electrical signal or other desired form of information output according to a certain rule. The sensing device 22 can include any type of sensor such as a temperature sensor, a pressure sensor, a gravity sensor, and a light sensor. For example, the sensing device 22 can be a device such as a smart home appliance, a terminal, and a vehicle. Any restrictions.

The gateway 21 can be used to receive data collected by the sensing device 22 and commands sent by the sensing device 22, and can also send data to other sensing devices 22 according to data or instructions collected by one or more sensing devices 22. Or instructions, etc.

In the embodiment of the present application, the gateway 21 may bind the plurality of sensing devices 22 having the binding relationship according to the linkage policy between the sensing devices 22. For example, the linkage strategy between the sensing device A and the sensing device B is: when the sensing device A is in the on state, the sensing device B is opened, that is, the binding between the sensing device A and the sensing device B Relationship, the device state of sensing device B depends on the device state of sensing device A. Then, before the sensing device A and the sensing device B implement the linkage process, the gateway 21 may first establish a binding relationship between the sensing device A and the sensing device B, and send a binding instruction to the sensing device A to The sensing device A is instructed to establish a binding relationship between the sensing device A and the sensing device B.

In this way, when the sensing device A detects that its device state is the on state, the sensing device B bound to the sensing device A can be directly determined according to the binding relationship, and according to the device state (ie, the open state) Generating a linkage instruction (for example, an opening instruction) to send to the sensing device B, the opening instruction is used to instruct the sensing device B to update its device state to an on state, thereby implementing between the sensing device A and the sensing device B. Linkage needs.

It can be seen that, in the linkage method of the sensing device provided by the embodiment of the present application, the first sensing device (for example, the sensing device A) can determine the binding according to the pre-acquired binding relationship without the participation of the gateway. The first sensing device has a second sensing device in a binding relationship (such as the sensing device B described above). In this way, the first sensing device can generate a corresponding linkage instruction (for example, the above-mentioned opening instruction) for the second sensing device according to the device state of the device (for example, the above-mentioned open state), and send the linkage command to the second sensing device. And causing the second sensing device to update its own device state according to the linkage instruction. In this way, the linkage process between the first sensing device and the second sensing device can be realized without the participation of the gateway, and even in the case that the gateway 21 is powered off, the first sensing device and the first sensing device can be realized. The linkage process between the two sensing devices, and the calculation pressure of the gateway 21 can be reduced, thereby reducing the deployment cost of the IoT.

Further, as shown in FIG. 3, a rule engine 23 may be disposed in the gateway 21, and the rule engine 23 may send a linkage policy between the first sensing device and the second sensing device to the first sensing device.

Among them, the linkage strategy includes two parts: linkage condition and linkage result. The linkage condition is used to indicate the device status of the first sensing device, and the linkage result is used to indicate the device status of the second sensing device. For example, the linkage policy 1 is: when the device state of the first sensing device is in the first target state, the device state of the second sensing device is the second target state, wherein the linkage condition is: the device of the first sensing device The state is in the first target state, and the linkage result is: the device state of the second sensing device is the second target state.

In this way, the first sensing device can determine the second target state of the second sensing device corresponding to the first target state of the first target device according to the linkage policy sent by the rule engine 23 in the gateway 21, for example, the second sensing device. The second sensing device can generate an opening command according to the opening state, that is, a linkage command, and send the signal to the second sensing device. Further, the second sensing device sets its own device according to the linkage instruction. The status is updated to an on state to cause the second sensing device to complete the linkage command.

Further, as shown in FIG. 4, an IoT cloud platform 24 may also be disposed in the linkage system 100. The IoT cloud platform 24 is connected to each gateway 21, and the first sensing device and the second sensing device are connected by the IoT cloud platform 24. The inter-linkage policy is sent to the rule engine 23 in the corresponding gateway 21.

In addition, as shown in FIG. 5, the IoT application 25 connected to the IoT cloud platform 24 may also be disposed in the linkage system 100, such that the user triggers management instructions for managing the sensing device 22 on any IoT application 25 (eg, unlocking the door lock) The IoT application 25 can send the management command to the IoT cloud platform 24, and the IoT cloud platform 24 sends the management command to the corresponding sensing device 22 through the gateway 21, and finally the corresponding sensing device 22 Execute the management instruction.

Hereinafter, a linkage method of a sensing device provided by an embodiment of the present application is described in detail in conjunction with a specific embodiment. As shown in FIG. 6, the method includes:

600. The gateway acquires a first description file of the first sensing device and a second description file of the second sensing device.

The first description file includes an instruction that allows the first sensing device to output, and the second description file includes an instruction that allows the second sensing device to receive.

In addition, the first description file may further include an instruction for allowing the first sensing device to receive, and the second description file may further include an instruction for allowing the output of the second sensing device, which is not limited by the embodiment of the present application.

Specifically, the gateway may obtain its device information from the first sensing device, for example, first device information, where the first device information includes an instruction that allows the first sensing device to output, and the gateway may also obtain the second sensing device from the second sensing device. Device information, for example, second device information, the second device information including instructions that allow the second sensing device to receive.

For example, when the first sensing device (or the second sensing device) communicates with the gateway using the Z-Wave protocol, the first device information (or the second device information) may specifically be NIF (node information). When the first sensing device (or the second sensing device) communicates with the gateway using the ZigBee protocol (Zigbee Protocol), the first device information (or the second device information) may specifically be the first sensing The match descriptor of the device (or second sensing device).

Taking NIF as an example, the NIF contains information as shown in Table 1, in which a special byte 0xEF is set in the NIF, and 0xEF divides the NIF into two parts, and a part is used to indicate n(n) that the sensing device is allowed to receive. ≥ 1) instructions, which can be expressed in the Z-Wave format command class (for example, supported command slass); the other part is used to indicate the m (m ≥ 1) instructions allowed by the sensing device, or Z- The command class of the Wave format (for example, the controlled command class) is represented. Then, after receiving the NIF (ie, the first device information) sent by the first sensing device, the gateway may map, by using a mapping manner, at least one of the n instructions that the first sensing device allows to receive, to be first. An instruction in the description file that allows the first sensing device to receive, and at least one of the m instructions that the first sensing device allows to output is mapped to an instruction in the first description file that allows the first sensing device to output. The instructions in the first description file that are allowed to be received by the first sensing device and the instructions that allow the first sensing device to output may be represented in the format of the IoT cloud platform.

Of course, it is also possible to record in the first description file the sensing device, such as the device characteristic information of the first sensing device, for example, the data collected by the first sensing device (for example, temperature value, humidity value, switch off or The state of the application, etc., is not limited in this embodiment.

Then, the first description file generated by the gateway according to the first device information of the first sensing device includes the information as shown in Table 2, wherein the current sensing power of the first sensing device is 40%, allowing the first sensing device to receive The instruction includes an open command, and the instruction that allows the first sensing device to output includes an open command and a close command.

Table 2

Similarly, when the device information of the first sensing device (or the second sensing device) is a match descriptor, the match descriptor includes two fields, InClusterList and OutClusterList. The InClusterList field includes an instruction that allows the sensing device to receive, and the OutClusterList field includes an instruction that allows the sensing device to output.

Then, after receiving the match descriptor (that is, the first device information) sent by the first sensing device, the gateway may also map the InClusterList field to an instruction in the first description file that allows the first sensing device to receive, The OutClusterList field is mapped to an instruction in the first description file that allows the first sensing device to output.

Similarly, the gateway may generate a second description file of the second sensing device according to the second device information of the second sensing device according to the above method.

In addition, the gateway may also obtain the first description file of the first sensing device and the second description file of the second sensing device from the IoT cloud platform, which is not limited in this embodiment.

601. The gateway acquires a linkage policy between the first sensing device and the second sensing device.

The linkage policy may specifically include a linkage condition and a linkage result, where the linkage condition is used to indicate that the device state of the first sensing device is the first target state, and the linkage result is used to indicate that the device state of the second sensing device is Two target states.

For example, the linkage strategy 1 is: when the temperature collected by the thermometer is greater than 30 degrees Celsius, the refrigeration device is turned on. Then, in the linkage strategy 1, the linkage condition is: the temperature collected by the thermometer (first sensing device) is greater than 30 degrees Celsius, that is, the temperature of the device state of the thermometer is greater than 30 degrees Celsius, and the linkage result is: opening the refrigeration device (second transmission Sensing device), that is, the device state of the cooling device is on.

Specifically, the linkage policy between the first sensing device and the second sensing device may be obtained from the IoT cloud platform by a rule engine in the gateway.

602. The gateway determines, according to the foregoing linkage policy, a binding relationship between the first sensing device and the second sensing device, where the binding relationship is used to indicate that the device state of the second sensing device is dependent on the device of the first sensing device. status.

Specifically, the gateway may determine, according to the first description file of the first sensing device, the second description file of the second sensing device, and the linkage policy acquired in step 602, the first sensing device and the second transmission. Whether there is a binding relationship between devices.

Exemplarily, when the instruction output by the first sensing device includes the first target instruction that performs the linkage condition, and the instruction received by the second sensing device includes the second target instruction that performs the linkage result, the gateway may determine The first sensing device has a binding relationship with the second sensing device. Otherwise, it can be determined that there is no binding relationship between the first sensing device and the second sensing device.

For example, the instruction output by the first sensing device includes an open command, and the command received by the second sensing device includes a close command. The linkage policy may be: when the first sensing device is turned on (the linkage condition), the second sensing device is turned off (the linkage result). It can be seen that the instruction output by the first sensing device includes an opening instruction (ie, a first target instruction) for executing the linkage condition, and the instruction received by the second sensing device includes a closing instruction for performing the linkage result (ie, the second The target command), then the gateway can determine that there is a binding relationship between the first sensing device and the second sensing device.

In addition, the near field communication protocol used by different sensing devices may be different. For example, the near field communication protocol used by the first sensing device is a Z-Wave protocol, and the near field communication protocol used by the second sensing device is a ZigBee protocol. Then, when determining whether the first sensing device and the second sensing device have a binding relationship, the gateway may further determine the near field communication protocol used by the first sensing device and the near field used by the second sensing device. Whether the communication protocol is the same.

When the near field communication protocol used by the first sensing device is the same as the near field communication protocol used by the second sensing device, and the instruction output by the first sensing device includes the first target instruction for executing the linkage condition, and the second When the instruction received by the sensing device includes the second target instruction for performing the linkage result, the gateway may determine that the first sensing device has a binding relationship with the second sensing device. Otherwise, it can be determined that there is no binding relationship between the first sensing device and the second sensing device.

603. The gateway sends a binding instruction to the first sensing device, where the binding instruction is used to indicate that the first sensing device establishes a binding relationship with the second sensing device.

After the gateway determines that the first sensing device has a binding relationship with the second sensing device, since the device state of the second sensing device is dependent on the device state of the first sensing device, the gateway may The first sensing device sends a binding command, which triggers the first sensing device to establish a binding relationship with the second sensing device. In this way, the subsequent first sensing device can determine whether to initiate a corresponding linkage instruction to the second sensor bound to itself according to its own device state.

Exemplarily, when the near field communication protocol used by the sensing device (for example, the first sensing device) is the Z-Wave protocol, the binding instruction may specifically be an association instruction; when the sensing device (for example, the first When the near field communication protocol used by the sensing device is the ZigBee protocol, the binding instruction may specifically be BindReq (combined instruction).

Certainly, a specific implementation form of the foregoing binding instruction may be set by a person skilled in the art according to actual experience or an actual application scenario, and the embodiment of the present application does not impose any limitation on this.

It should be noted that the gateway and the rule engine may use the command format of the IoT platform format to perform the interaction, and the near field protocol format may be used for interaction.

After the first sensing device establishes the binding relationship with the second sensing device, the following steps 604-607 may be performed to implement linkage between the first sensing device and the second sensing device. process.

604. The first sensing device determines that the device state of the current first sensing device is the first target state.

Exemplarily, as shown in FIG. 5, the user can trigger the management instruction of the management sensing device 22 through the IoT application 25, for example, the management command is an open command of the door lock (ie, the first sensing device). Then, the IoT application 25 can send the open command to the IoT cloud platform 24, and the IoT cloud platform 24 sends the open command to the door lock through the gateway 21, and the open command is executed by the door lock. At this point, the door lock can determine that the current device state is the on state.

Or, during the operation of the first sensing device, the device state of the device may be determined according to the currently collected data. For example, the temperature sensing device can collect the current temperature value in real time and use the temperature indicated by the current temperature value as its first target state.

605. The first sensing device determines, according to the binding relationship, a second sensing device that is bound to the first sensing device.

606. The first sensing device generates a linkage instruction according to the first target state, where the linkage instruction is used to instruct the second sensing device to update the device state of the second sensing device to the second target state.

Specifically, in step 604, the first sensing device can determine its current device state according to the currently collected data. For example, the pressure sensing device can convert the currently collected pressure signal into an electrical signal to determine the current pressure. The value of the door and window sensing device can determine whether the state of the current door is the open state or the closed state according to the state of the current door lock.

Then, in step 603, the first sensing device has established a binding relationship with the second sensing device. Therefore, in step 605, the first sensing device may determine the binding according to the binding relationship. The second sensing device to which the first sensing device has been bound.

The device state of the second sensing device depends on the device state of the first sensing device. Then, in step 606, the first sensing device may generate the second sensing device according to the first target state determined in step 604. Linkage instructions.

In one possible design method, the first sensing device may determine its own first target state as the device state of the second sensing device, ie, the second target state is the same as the first target state. Then, the first sensing device can directly generate a linkage instruction according to the first target state. At this time, the linkage instruction carries the identifier of the first target state.

For example, the first target state of the door lock (first sensing device) is an open state (first target state), and at this time, the first sensing device can directly identify the first target state, for example, the identifier: on, As a linkage command sent to the electric light (second sensing device). Subsequently, the electric light can directly execute the linkage instruction, and update its own device state to the same device state as the door lock, that is, execute an instruction to turn on the light.

In another possible design method, the linkage policy between the first sensing device and the second sensing device may be stored in the first sensing device in advance, for example, the linkage strategy is: when the first sensing device When turned on, the second sensing device is turned off. Then, in step 606, the first sensing device may first search for the second target state corresponding to the first target state (for example, the open state), that is, the closed state, from the linkage policy. Further, the first sensing device carries the determined identification of the closed state in the linkage instruction and sends the identifier to the second sensing device. Subsequently, the second sensing device can update its own device state to the closed state according to the identifier of the closed state in the linkage instruction, that is, execute the shutdown command.

In another possible design method, the linkage policy between the first sensing device and the second sensing device may be stored in the second sensing device in advance, for example, the linkage strategy is still: when the first sensing When the device is turned on, the second sensing device is turned off. Then, in step 606, the first sensing device carries the identifier of the first target state of the first sensing device in the linkage instruction and sends it to the second sensing device. Subsequently, the second sensing device may search for the second target state corresponding to the first target state (for example, the open state) from the linkage policy according to the identifier of the first target state in the linkage command, that is, the shutdown state, and further, the second The sensing device can update its own device status to the off state.

607. The first sensing device sends a linkage instruction to the second sensing device to implement a linkage process between the first sensing device and the second sensing device.

In this way, in steps 604-607, even if the gateway is powered off or the computing performance is insufficient, the linkage process between the first sensing device and the second sensing device can be implemented, thereby reducing the deployment cost of the IoT.

Optionally, after the first sensing device generates the linkage command, as shown in FIG. 6, the linkage method may further include steps 608-609.

608. The first sensing device sends a linkage instruction to the gateway.

609. When the first sensing device and the second sensing device have a binding relationship, the gateway discards the linkage instruction.

In step 608, the first sensing device may further send the linkage command to the gateway. At this time, when the rule engine in the gateway queries that the first sensing device and the second sensing device are already stored, When the relationship is bound, the gateway has indicated that the first sensing device establishes a binding relationship with the second sensing device. Then, in step 609, the gateway may directly discard the linkage command to avoid the second sensing. The device repeatedly executes the linkage instruction.

Certainly, if the rule engine does not query the binding relationship between the first sensing device and the second sensing device, the correlation engine may send the linkage instruction to the second sensing device through the gateway by using the prior art. The linkage instruction is executed by the second sensing device to complete the linkage process between the first sensing device and the second sensing device.
