Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The linkage control method based on the Internet of things can be applied to the application environment shown in the figure 1. The signal acquisition device 102 may communicate with the edge server 104 through a network, and the edge server 104 may communicate with the central server 106 and the target device 108 through a network, respectively. The edge server 104 may receive the environmental signal uploaded by the signal acquisition device 102, and invoke a policy matching model, which is established based on the linkage policy sent by the central server 106. And the edge server 104 performs strategy matching on the environment signal according to the strategy matching model to obtain a target linkage strategy matched with the environment signal. The edge server 104 determines the target device to be linked according to the target linkage strategy, and generates a linkage control instruction based on the target linkage strategy. The edge server 104 sends the linkage control instruction to the target device 108, where the linkage control instruction is used to control the target device 108 to execute a linkage task corresponding to the linkage control instruction. The signal acquisition device 102 may include, but is not limited to, various devices capable of acquiring measured signals and converting the measured signals into usable signals according to a certain rule. The edge server 104 and the central server 106 may each be implemented as a stand-alone server or as a server cluster of multiple servers. The target device 108 may be a variety of devices to be controlled in conjunction.
In one embodiment, as shown in fig. 2, a linkage control method based on the internet of things is provided, which is described by taking the method as an example applied to the edge server 104 in fig. 1, and includes the following steps:
The edge server is a server which is close to one side of the signal acquisition device and the target equipment and performs linkage control nearby, and is used for performing edge calculation. The edge server may be a single independent server or may be a server cluster comprising a plurality of servers. The edge server may specifically be a controller corresponding to a central server, and one central server may correspond to two or more edge servers. One edge server may be associated with one or more signal acquisition devices, and the edge server may receive the environmental signal uploaded by the corresponding at least one signal acquisition device. The signal acquisition device can be arranged on various devices and can be used for acquiring the measured signals in the practical application environment. The environment signal may specifically include, but is not limited to, at least one of a temperature signal, a video signal, and a coordinate signal. For example, the signal acquisition device may specifically be a camera device, and is configured to acquire a video signal in the corresponding area. The signal acquisition device may be provided on the corresponding apparatus. For example, can be provided with signal acquisition device on the intelligence well lid to this coordinate signal through signal acquisition device detection intelligence well lid avoids the intelligence well lid to lose. Each signal acquisition device can be provided with corresponding trigger condition according to the practical application demand, and when the environmental information that signal acquisition device detected satisfies trigger condition, signal acquisition device can upload the environmental signal to corresponding edge server. For example, the triggering condition corresponding to the signal acquisition device of the intelligent well lid comprises a coordinate range, and when the coordinate signal detected by the signal acquisition device is not in the preset coordinate range, the environment signal is determined to meet the triggering condition, and the triggered coordinate signal is uploaded to the edge server. The edge server can receive the environment signal uploaded by the signal acquisition device, analyze the environment signal and perform linkage control on the linkage equipment to be linked according to the environment signal.
And step 204, calling a strategy matching model, wherein the strategy matching model is established based on the linkage strategy sent by the central server.
The edge server may invoke a policy matching model, which may be pre-established and configured in the edge server, so that the edge server invokes the policy matching model to perform policy matching on the environment signal. The strategy matching model can be established based on the linkage strategy sent by the central server. Specifically, a user can communicate with the central server through the corresponding user terminal, the user terminal can access the central platform corresponding to the central server, the user can select the equipment to be linked with the signal acquisition device through the user terminal, the signal acquisition device and the linkage strategy corresponding to the equipment to be linked are preset, and the flexibility of the linkage strategy is improved so as to perform corresponding linkage control in multiple different application environments. The user terminal may specifically include, but is not limited to, various personal computers, notebook computers, tablet computers, smart phones, portable wearable devices, and the like.
The central server can transmit the linkage strategy formulated by the user to the corresponding edge servers according to a preset transmission mode, and the central server and the edge servers can perform synchronous transmission or asynchronous transmission. The user can newly add the linkage strategy through the user terminal according to actual requirements, and the central server can send the newly added linkage strategy to the edge server, so that transmission resources between the central server and the edge server are saved. After receiving the linkage policy, the edge server may return confirmation information to the central server, where the confirmation information includes an edge server identifier, and determines that the edge server corresponding to the edge server identifier has received the linkage policy. In one embodiment, when the central server does not receive the confirmation information returned by the edge server within the preset time period, the central server may resend the linkage policy to the edge server that does not receive the linkage policy, so that it is ensured that all the edge servers corresponding to the central server receive the linkage policy formulated by the user, and accurate synchronization of the linkage policy is ensured.
After receiving the linkage strategy issued by the central server, the edge server can analyze the linkage strategy and establish a strategy matching model according to the linkage strategy. Specifically, the linkage strategy may be a set of multiple linkage modes, and the linkage strategy may specifically include an association relationship among the signal acquisition device, the environment signal, the device to be linked, and the linkage mode. The edge server can establish a strategy matching model according to the incidence relation in the linkage strategy, and the edge server can store the linkage strategy and the strategy matching model issued by the central server in a local database corresponding to the edge server so as to call the established strategy matching model from the local database to perform strategy matching on the received environment signal. Even under the condition that the communication with the central server cannot be realized, the target equipment can be subjected to linkage control in time, and the efficiency and the robustness of the linkage control are improved.
And step 206, performing strategy matching on the environment signal according to the strategy matching model to obtain a target linkage strategy matched with the environment signal.
The edge server can input the received environment signal to the strategy matching model, and strategy matching is carried out on the environment signal according to the strategy matching model to obtain a target linkage strategy matched with the environment signal. Specifically, the strategy matching model comprises a plurality of linkage strategies preset by the user, and the strategy matching model can match the input environment signal with the linkage strategies stored in the local database and search whether the linkage strategies matched with the environment signal exist in the local database of the edge server. The linkage strategy comprises the incidence relation between the environment signal and the linkage mode and other information, and the edge server can search the linkage strategy matched with the environment signal from the plurality of linkage strategies. When the linkage strategy matched with the environment signal does not exist, the strategy matching is determined to be failed, and the edge server can not respond to the environment signal uploaded by the signal acquisition device. And when the linkage strategy matched with the environmental signal exists, determining that the strategy is successfully matched, and the edge server can determine the matched linkage strategy as a target linkage strategy to obtain the target linkage strategy matched with the strategy matching model output.
And 208, determining target equipment to be linked according to the target linkage strategy.
The edge server can determine target equipment to be linked according to the target linkage strategy. The target device is a device which needs to be subjected to linkage control in the devices to be linked corresponding to the edge server, and the devices to be linked specifically may include, but are not limited to, a broadcasting device, a display device, a monitoring device, and the like. The edge servers can respectively correspond to the signal acquisition devices and the equipment to be linked. For example, in an application environment of a smart city, signal acquisition devices and devices to be linked are arranged at multiple positions in the city, an edge server may be arranged in each street in the city, and the edge server may communicate with all the signal acquisition devices and the devices to be linked in the corresponding street through a network.
Specifically, the edge server may communicate with the signal acquisition device according to a preset transmission protocol, and the server may obtain port information corresponding to the signal acquisition device that uploads the environmental signal when the signal acquisition device uploads the environmental signal. The port is an exit of the signal acquisition device communicating with the edge server, and the port of the signal acquisition device may be uniquely corresponding to the signal acquisition device. The edge server can determine the position information of the signal acquisition device according to the port information corresponding to the signal acquisition device. The edge server can determine the trigger event of the trigger signal acquisition device according to the environment signal, and the linkage mode and the linkage range are also determined in the target linkage strategy matched with the environment signal.
In different application environments of the internet of things, target linkage strategies corresponding to the environment signals are different according to different actual application requirements. For example, in the application environment of smart home, the signal acquisition device may be disposed on an air conditioner, when the temperature signal acquired by the signal acquisition device reaches a trigger condition, the signal acquisition device may upload the temperature signal, the linkage mode in the corresponding target linkage strategy may be to perform linkage control on the air conditioning equipment in the room corresponding to the signal acquisition device, and the linkage range is the air conditioning equipment corresponding to the signal acquisition device. And in the application environment of the smart city, when the intelligent well lid is lost, the linkage range corresponding to the target linkage strategy can be a street or a whole block where the intelligent well lid is located. The devices to be linked which need to be linked in different linkage modes can also be different. For example, when the linkage manner is a voice prompt, the corresponding target device may be a broadcasting device. When the linkage mode is monitoring, the corresponding target device may be a monitoring device. The edge server can use the position information corresponding to the signal acquisition device as a reference, and determine matched equipment to be linked as target equipment needing linkage control according to the linkage mode and the linkage range corresponding to the environment signal and the target linkage strategy. The target device may be a device to be linked corresponding to an edge server that receives the environment signal, or may be a device to be linked corresponding to another edge server that corresponds to the center server.
And step 210, generating a linkage control instruction based on the target linkage strategy, and sending the linkage control instruction to the target equipment, wherein the linkage control instruction is used for controlling the target equipment to execute a corresponding linkage task.
The edge server can generate linkage control instructions based on the target linkage strategy and send the linkage control instructions to the target equipment. The target device can receive the linkage control instruction sent by the edge server, generate and execute the linkage task according to the received linkage control instruction, and perform linkage operation corresponding to the linkage control instruction. For example, the monitoring device may execute a corresponding monitoring task according to the linkage control instruction, and acquire video data in a corresponding area. The broadcasting equipment can show corresponding voice prompt information through the loudspeaker according to the linkage control instruction. When two or more target devices are included, the edge server may generate linkage control instructions for the plurality of target devices, respectively, and control the plurality of target devices to execute corresponding linkage tasks simultaneously or sequentially.
In this embodiment, the edge server receives an environmental signal uploaded by the signal acquisition device, and invokes a policy matching model established based on a linkage policy sent by the central server to perform policy matching on the environmental signal, so as to obtain a target linkage policy matched with the environmental signal. The edge server can generate linkage control instructions based on the target linkage strategy, and the linkage control instructions are sent to corresponding target equipment so as to control the target equipment to execute corresponding linkage tasks. Compared with the traditional linkage method, the edge server is close to the signal acquisition device and the target equipment, and the transmission time delay of the environmental signal and the linkage control instruction is reduced. The whole application environment can comprise a plurality of edge servers, so that the data volume required to be processed by each edge server is reduced, the requirement on transmission network bandwidth is lowered, the time delay of responding to an environment signal is effectively reduced, the linkage control efficiency is improved, and the application environment with higher requirement on the real-time property of the linkage control can be met.
In one embodiment, after receiving the environmental signal uploaded by the signal acquisition device, the method for linkage control based on the internet of things further includes: classifying the environment signals to obtain signal types corresponding to the environment signals; screening the environmental signals based on the signal type; and performing strategy matching on the screened environmental signals according to the strategy matching model.
Before strategy matching is carried out on the environment signals uploaded by the signal acquisition device, the edge server can also classify the received environment signals to obtain signal types corresponding to the environment signals, and the environment signals are screened according to the signal types. Specifically, the edge server may correspondingly receive the environmental signals uploaded by the plurality of signal acquisition devices, and the plurality of signal acquisition devices may upload the environmental signals due to the same trigger event, so that the edge server does not need to perform the linkage control repeatedly on the same trigger event. The edge server can analyze the environment signals uploaded by two or more signal acquisition devices after receiving the environment signals, label marks the environment signals respectively, and classifies the environment signals according to the signal labels to obtain the signal types corresponding to the environment signals. The edge server can screen the environment signals based on the signal types corresponding to the environment signals, filter repeated environment signals in a plurality of environment signals, and call the strategy matching model to perform strategy matching on the screened environment signals.
In this embodiment, the edge server performs classified triggering on the received environment signals, screens the environment signals based on the signal types corresponding to the environment signals, and calls the policy matching model to perform policy matching on the screened environment signals, so that unnecessary linkage control is avoided being repeatedly performed by the edge server, the operation resources of the edge server are saved, and the efficiency of the linkage control is effectively improved.
In an embodiment, as shown in fig. 3, after the step of determining a target device corresponding to the signal acquisition device according to the environmental signal and the target linkage policy, the linkage control method based on the internet of things further includes:
and 302, generating a linkage control request according to the target linkage strategy, wherein the linkage control request carries a target equipment identifier.
And step 306, uploading the linkage control request to a central server when the detection is successful, so that the central server issues a target linkage strategy to the edge server corresponding to the target equipment identifier.
The central server can correspond to a plurality of edge servers, and each edge server can correspond to a plurality of signal acquisition devices and equipment to be linked respectively. It is to be understood that, for the sake of convenience of distinction, an edge server that receives the environment signal uploaded by the signal acquisition device may be referred to as a first edge server, and at least one edge server other than the first edge server may be referred to as a second edge server. The first edge server can receive the environment signal uploaded by the signal acquisition device, and the strategy matching model is called to perform strategy matching on the environment signal to obtain a target linkage strategy matched with the environment signal. The first edge server can determine target equipment needing linkage control according to the environment signal and the target linkage strategy. When the linkage range corresponding to the target linkage strategy is small, the corresponding target device may be at least one of the first devices to be linked corresponding to the first edge server, and the first edge server may generate a linkage control instruction based on the target linkage strategy, and perform linkage control on the first target device corresponding to the first edge server according to the linkage control instruction.
When the linkage range corresponding to the target linkage strategy is large, the corresponding target device may further include a second target device corresponding to at least one second edge server. For example, each street in a smart city corresponds to an edge server. When the intelligent well lid in the wisdom urban area is lost, the edge server that the street that intelligence well lid place corresponds is first edge server, and the edge server that other streets correspond is second edge server. The target device determined by the first edge server according to the target linkage policy may include a first monitoring device corresponding to the first edge server, and may further include a second monitoring device corresponding to the second edge server.
When the target device corresponding to the target linkage policy includes a second target device, the first edge server may generate a linkage control request according to the target linkage policy, where the linkage control request carries a target device identifier corresponding to the second target device. And the first edge server can perform linkage control on the second target equipment corresponding to the target equipment identifier by linking the second edge server according to the linkage control request.
Specifically, the first edge server may detect a communication connection between the first edge server and the central server, and determine whether the communication connection between the first edge server and the central server is connected. When the communication connection between the first edge server and the central server is connected, the detection is determined to be successful, and the first edge server can communicate with the central server. When the communication connection between the first edge server and the central server is disconnected, the connection is determined to be failed, and the first edge server cannot communicate with the central server.
And when the detection result is that the detection is successful, the first edge server can transmit the linkage control request to the central server through the communication connection, so that the central server sends a target linkage strategy to a second edge server to which a second target device corresponding to the target device identifier belongs according to the linkage control request. The target equipment identifier is carried in the linkage control request, and the second edge server can perform linkage control on the second target equipment according to a target linkage strategy issued by the central server.
In one embodiment, when the detection result is detection failure, the first edge server may establish a communication connection with the second edge server through the ad hoc network. The first edge server can send the linkage control request to the second edge server through the established communication connection, the second edge server determines a target linkage strategy according to the received linkage control request, and linkage control is carried out on second target equipment corresponding to the target equipment identification according to the target linkage strategy. The first edge server can directly establish communication connection with the second edge server, and when the first edge server is disconnected from the central server or the central server cannot process the data, the first edge server can perform linkage control on the second target device in time through communication connection with the second edge server, does not depend on the central server completely, and effectively improves the stability and robustness of the linkage control.
In this embodiment, when the target device corresponding to the target linkage policy includes a second target device corresponding to the second edge server, the first edge server may generate a linkage control request according to the target linkage policy, and send the linkage control request to the center server or the second edge server, so as to perform linkage control on the second target device corresponding to the second edge server according to the linkage control request, thereby ensuring a linkage range of the edge server for linkage control, being capable of performing linkage control on the target device in time, and effectively improving the efficiency of the linkage control.
In one embodiment, after the step of sending the linkage control command to the target device, the method for linkage control based on the internet of things further includes: receiving linkage information returned by the target equipment based on the linkage control instruction; and generating alarm information according to the environment signal and the linkage information, and sending the alarm information to the central server.
The edge server can send the linkage control instruction to the target equipment, and linkage control is carried out on the target equipment through the linkage control instruction, so that the target equipment generates a linkage task according to the linkage control instruction and executes the linkage task. The target device may return linkage information corresponding to the linkage task to the edge server after executing the linkage task, and the edge server may receive the linkage information returned by the target device based on the linkage control instruction. The linkage information may specifically include a linkage result obtained after the target device executes the linkage task according to the linkage control instruction. For example, when the target device is a display device, the display device may execute a display task according to the linkage control instruction, display information such as corresponding text and image through a display interface, and return a display result. When the target device is a monitoring device, the monitoring device can execute a monitoring task according to the linkage control, collect video data of a corresponding monitoring area, and the returned linkage information can be the collected video data.
The edge server can generate alarm information according to the environment signal and the linkage information by combining the environment signal uploaded by the signal acquisition device and the linkage information returned by the target equipment. In one embodiment, the edge server may further perform preset processing on the linkage information returned by the target device, where the preset processing mode may be corresponding to the type of the linkage information. The edge server can generate alarm information according to the processed linkage information. For example, when the target device is a monitoring device and the linkage information returned by the monitoring device is video data, the edge server can perform target identification processing on the video data to obtain target information identified from the video data, and the edge server can generate alarm information according to the target information and the environmental signal without uploading the whole video data to the central server, so that transmission resources between the edge server and the central server and operation resources of the central server are effectively saved.
The edge server can send the generated alarm information to the central server, the central server can send the alarm information to the user terminal, and the alarm information is displayed to the user through the user terminal. In one embodiment, when the central server receives the alarm information sent by the edge servers, the multiple alarm information can be screened, repeated alarm information in the multiple alarm information is filtered, repeated alarm information is prevented from being sent to the user terminal repeatedly, the operation resource and the transmission resource of the central server are saved, and the user experience is improved.
In this embodiment, the edge server may receive linkage information returned by the target device based on the linkage control instruction, generate alarm information according to the environment signal and the linkage information, and send the alarm information to the central server, thereby saving the operation resources of the central server. The central server can send the alarm information to the user terminal, and the user can know the linkage control event through the user terminal.
