Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0039] It should also be understood that the term "and / or" used in the specification and the appended claims of the present application means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0040] In the current field of distributed sensors, it is a common design direction to give a specific distributed sensor system design based on a specific scene. Designing a distributed sensor system according to a specific scene is a very tedious and time-consuming process. At present, there is no very common and universal distributed sensor system template to provide an "out-of-the-box" solution.

[0041] When the heterogeneity of the sensor system is complex, such as two or more sensors detecting an area, the sensor system is difficult to divide the work and also difficult to communicate well with the server, resulting in the distributed sensor system transmitting redundant data back to the background, and there is a problem of poor communication quality. The current distributed sensor system has communication and data fusion functions (eliminating redundant data), but it is not universal, and the communication, data fusion and business capabilities are still not robust enough.

[0042] Please refer to Figure 1 , Figure 1 The application scenario of the control method of the sensor system provided by the embodiments of the present application is shown in the figure. The application scenario of the control method of the sensor system will be described below. Figure 1 The application scenario of the control method of the sensor system will be described below.

[0043] As Figure 1 shown, the control method of the sensor system is applied to a sensor system or a computer device. The control method of the sensor system can establish a distributed soft bus among multiple sensors, realize flexible selection of sensors by the sensor system through the distributed soft bus, and realize efficient transmission of data among devices, thereby realizing seamless switching among sensors. The operation process of configuring the sensor system between different devices is simplified, efficient circulation of data among multiple sensors is realized, and the user experience is improved.

[0044] It should be noted that the communication connection between the sensors 11 and the sensors 11 can be a wired connection or a wireless connection, for example, can be connected through Wi-Fi, Bluetooth, Ethernet, 3G communication, 4G communication, 5G communication and the like. The sensors 11 and the sensors 11 can be independent of each other, and can be arranged at different spatial positions, or can be integrated in the same device. Among them, the distributed soft bus is based on the cooperation of Ethernet, WIFI and Bluetooth, and provides the discovery and connection functions between devices. After the devices are discovered and connected with each other, the distributed soft bus manages the ad hoc network and the topological relationship between the devices, so that the devices in the whole scene can complete device virtualization, cross-device service calling, multi-screen cooperation, file sharing and other distributed businesses based on the distributed soft bus.

[0045] As shown in Figure 2 , the control method of the sensor system provided by the embodiments of the present application can be applied to the application environment as shown in Figure 2 . The application environment includes a sensor system 110 and a server 120, wherein the computer device in the sensor system 110 can communicate with the server 120 through a distributed soft bus. Specifically, the sensor system 110 obtains the types of multiple sensors, and groups the sensor clusters according to the types of the sensors to obtain multiple sensor groups; obtains the working requirements of the sensors, and determines the working mode of the sensor groups according to the working requirements of the sensors; if the working mode of the sensor group is a center mode, a target sensor corresponding to the sensor group is determined; the sensors in the sensor group are controlled to collect environmental data, and the environmental data collected by each sensor is sent to the target sensor through the distributed soft bus, so that the sensor sends the environmental data to the server 120 through the distributed soft bus; if the working mode of the sensor group is a centerless mode, the sensors in the sensor group are controlled to collect environmental data, and the environmental data is sent to the server 120 through the distributed soft bus. The server 120 can be an independent server, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content distribution networks (Content Delivery Network, CDN), and big data and artificial intelligence platforms, and the like. Basic cloud computing services. The sensor system 110 can include a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, and the like, but is not limited thereto. The sensor system and the server can be directly or indirectly connected through wired or wireless communication, which is not limited in the present application.

[0046] Please refer to Figure 3 , Figure 3is a flowchart of a sensor system control method provided by an embodiment of the present application. The sensor system control method can be applied in a sensor system.

[0047] As shown in Figure 4 , the sensor system includes a sensor cluster and is connected with a server (background / cloud) through a distributed soft bus for controlling the work of sensors in the sensor cluster, the sensor cluster includes a plurality of sensors, and the plurality of sensors are connected through the distributed soft bus to form the sensor cluster.

[0048] Among them, the sensors can include various types of sensors such as temperature sensors, humidity sensors, etc., and the sensors are connected through the distributed soft bus to form the sensor cluster.

[0049] As shown in Figure 3 , the sensor system control method includes steps S101 to S105.

[0050] S101, obtain the types of the plurality of sensors, and group divide the sensor cluster according to the types of the sensors to obtain a plurality of sensor groups.

[0051] Among them, the types of the sensors can be determined by the data types collected by the sensors, such as temperature sensors, humidity sensors, ultraviolet sensors, and volume sensors. The sensor cluster can be composed of a plurality of sensors, which can include sensors of the same type or sensors of different types. The sensor group can be composed of sensors of the same type, and it should be noted that the sensor types in different sensor groups are different.

[0052] In some embodiments, the device information of the sensors is obtained, and the device information is parsed to obtain the device model of the sensors and the data type collected by the sensors; and the type of the sensor is determined according to the device model of the sensor and the data type collected by the sensor. Thus, the types of the sensors can be accurately determined according to the device information.

[0053] Among them, the device information of the sensor can include device code, device model, etc. The device model of the sensor is the corresponding production model of each manufacturer, which is used to determine the data type collected by the sensor.

[0054] For example, the device information of the sensor such as the device code can be obtained, and the device information is parsed to obtain the device model of the sensor and the data type collected by the sensor, which is temperature data. Thus, the type of the sensor can be determined as a temperature sensor.

[0055] It should be noted that the type of each sensor can be determined by obtaining the device information of each sensor; if the sensor has been used or registered on the server, the type of the sensor can also be directly obtained from the server.

[0056] In some embodiments, in the sensor cluster, it is determined whether there are multiple sensors of the same type; if there are multiple sensors of the same type in the sensor cluster, the multiple sensors of the same type are taken as one sensor group; if the type of the sensor is different from the types of the remaining sensors in the sensor cluster, the sensor is taken as one sensor group. Thus, the sensor groups can be accurately divided according to the types of the sensors.

[0057] Specifically, the sensor cluster can be grouped according to the types of the sensors, so that the sensors of the same type are divided into one sensor group, thereby obtaining multiple sensor groups.

[0058] For example, if there are multiple sensor A and multiple sensor B in the sensor cluster, and the types of the sensor A are the same and the types of the sensor B are the same, the multiple sensor A are taken as one sensor group and the multiple sensor B are taken as one sensor group.

[0059] For example, if there is only one sensor A in the sensor cluster, the sensor A is taken as one sensor group.

[0060] As shown in Figure 5 For example, the sensor cluster includes multiple types of sensors, such as sensor A, sensor B, sensor C, and sensor D. Therefore, the sensor cluster can be grouped according to the types of the sensors, so that the sensors of the same type are divided into one sensor group, i.e., the first sensor group includes sensor A, the second sensor group includes sensor B, the third sensor group includes sensor C, and the fourth sensor group includes sensor D, thereby obtaining multiple sensor groups.

[0061] The cloud background can divide each sensor into a logical workspace, rather than a physical workspace. For example, when there are multiple different types of sensors (light sensor, temperature sensor, and humidity sensor) in a sensor cluster, and the sensors are scattered in different spaces, the background can divide the different types of sensors into different sensor groups, so that data fusion and background data processing are more convenient during data transmission.

[0062] It should be noted that different sensor groups are isolated in communication, which can reduce the power consumption caused by communication, thereby making data fusion more rapid, etc.

[0063] S102, acquire the working requirement of the sensor, and determine the working mode of the sensor group according to the working requirement of the sensor.

[0064] The working requirement of the sensor can be used to select a device for data processing, thereby determining the working mode of the sensor group. The working mode of the sensor group can include a centralized mode and a non-centralized mode.

[0065] For example, if the user wants the cloud / background to process data, the non-centralized mode can be selected, and if the user wants the sensor system to process data, the centralized mode can be selected.

[0066] In some embodiments, the device state of the sensor is acquired, and the working condition supported by the sensor is determined according to the device state; and the working requirement of the sensor is determined according to the working condition supported by the sensor. Thus, the working requirement of the sensor can be accurately determined according to the device state of the sensor.

[0067] The device state includes signal strength, remaining power, and the number of devices within a preset range, and the working condition supported by the sensor is the best data processing condition and the best data transmission condition that the sensor can achieve. Since the centralized mode requires a sensor from the sensor cluster to process data and transmit data, there must be a sensor in the sensor cluster that meets the data processing condition and the data transmission condition, so that the sensor system can work in the centralized mode.

[0068] Specifically, the working condition supported by the sensor can be determined according to the device state of the sensor, such as signal strength, remaining power, and the number of devices within a preset range. If it is determined that the working condition supported by the sensor meets the working condition corresponding to the centralized mode, the working requirement of the sensor can be the centralized mode; if it is determined that the working condition supported by the sensor does not meet the working condition corresponding to the centralized mode, the working requirement of the sensor can be the non-centralized mode.

[0069] It should be noted that the working condition supported by all sensors in the sensor cluster can be determined by detecting all sensors in the sensor cluster. If it is determined that at least one sensor in the sensor cluster supports a working condition that meets the working condition corresponding to the centralized mode, the working requirement of the sensor can be the centralized mode; if it is determined that all sensors in the sensor cluster do not support a working condition that meets the working condition corresponding to the centralized mode, the working requirement of the sensor can be the non-centralized mode.

[0070] Exemplarily, the device state of one of the sensors in the sensor cluster can be determined, such as signal strength of -100 dbm, remaining power of 30%, and the number of devices in the preset range of 3, and the working condition corresponding to the hub mode is that the signal strength is higher than -95 dbm, the remaining power is higher than 20%, and the number of devices in the preset range is less than 4. Thus, it can be determined that the working condition supported by the sensor meets the working condition corresponding to the hub mode, and the working requirement of the sensor can be the hub mode.

[0071] Exemplarily, the device state of one of the sensors in the sensor cluster can be determined, such as signal strength of -100 dbm, remaining power of 30%, and the number of devices in the preset range of 3, and the working condition corresponding to the hub mode is that the signal strength is higher than -95 dbm, the remaining power is higher than 20%, and the number of devices in the preset range is less than 4. Thus, it can be determined that the working condition supported by the sensor meets the working condition corresponding to the hub mode, and the working requirement of the sensor can be the hub mode.

[0072] It should be noted that if any one of the device states of the sensor does not meet the working condition corresponding to the hub mode, it can be considered that the working condition supported by the sensor does not meet the working condition corresponding to the hub mode.

[0073] S103, if the working mode of the sensor group is the hub mode, determining the target sensor corresponding to the sensor group.

[0074] The target sensor can be a master sensor in the sensor group, which is used for data communication and data processing.

[0075] In some embodiments, the device state of the sensor is obtained, and the target sensor is determined from the sensor group according to the device state of the sensor. Thus, the target sensor can be accurately determined from the corresponding sensor group according to the device state of the sensor.

[0076] The device state can include signal strength, remaining power, and the number of devices in the preset range. The signal strength can represent the communication capability of the sensor, the remaining power can represent the endurance capability of the sensor, and the number of devices in the preset range can represent the anti-interference capability of the sensor. The preset range can be a certain range, the preset range can be a circle with a certain point as the center and a certain length as the radius, or a square with a certain point as the center and a certain length as the length, which is not limited here.

[0077] Specifically, the communication capability of the sensor can be determined according to the signal strength of the sensor; the endurance capability of the sensor can be determined according to the remaining power of the sensor; and the anti-interference capability of the sensor can be determined according to the number of devices within the preset range; thereby the target sensor is determined from the corresponding sensor group according to the communication capability, the endurance capability and the anti-interference capability of the sensor.

[0078] In some embodiments, the signal strength, the remaining power and the number of devices within the preset range of the sensor are determined; the device performance of the sensor is determined according to the signal strength, the remaining power and the number of devices within the preset range of the sensor; and the target sensor is determined from the sensor group according to the device performance of the sensor. Thus, the target sensor can be accurately determined from the sensor group by determining the device performance of the sensor.

[0079] The device performance of the sensor can include the communication capability, the endurance capability and the anti-interference capability of the sensor, and the device performance of the sensor is determined according to the communication capability, the endurance capability and the anti-interference capability of the sensor.

[0080] Specifically, the corresponding weight proportions can be configured for the communication capability, the endurance capability and the anti-interference capability of the sensor, respectively, thereby the device performance of the sensor is determined, and one or more sensors with the best device performance are selected as the target sensor.

[0081] For example, if the score of the communication capability of the sensor A is 80, the weight proportion is 50%, the score of the endurance capability is 70, the weight proportion is 30%, and the score of the anti-interference capability is 80, the weight proportion is 20%, then the score of the device performance of the sensor A can be determined as 76; if the score of the communication capability of the sensor B is 90, the weight proportion is 50%, the score of the endurance capability is 60, the weight proportion is 30%, and the score of the anti-interference capability is 90, the weight proportion is 20%, then the score of the device performance of the sensor B can be determined as 81; and the target sensor can be determined as the sensor B.

[0082] For example, if the score of the communication capability of sensor A is 80, the weight ratio is 50%, the score of the endurance capability is 70, the weight ratio is 30%, and the score of the anti-interference capability is 80, the weight ratio is 20%, the score of the device performance of sensor A can be determined as 76; if the score of the communication capability of sensor B is 90, the weight ratio is 50%, the score of the endurance capability is 60, the weight ratio is 30%, and the score of the anti-interference capability is 90, the weight ratio is 20%, the score of the device performance of sensor B can be determined as 81; if the score of the communication capability of sensor C is 95, the weight ratio is 50%, the score of the endurance capability is 70, the weight ratio is 30%, and the score of the anti-interference capability is 70, the weight ratio is 20%, the score of the device performance of sensor C can be determined as 82.5; and the target sensors can be determined as sensor B and sensor C.

[0083] As shown in FIG. 1, for example, when the sensor group works in the center mode, the sensor group selects one or more master devices as the target sensors (master devices) of the sensor group, such as the sensors in the gray part in FIG. 1. Figure 6 As shown in FIG. 1, for example, when the sensor group works in the center mode, the sensor group selects one or more master devices as the target sensors (master devices) of the sensor group, such as the sensors in the gray part in FIG. 1. Figure 6 In this mode, the sensor group communicates with the cloud background through the target sensors. The monitoring data collected by the slave sensors is sent to the target sensors, and the target sensors process the received data, such as data fusion: eliminating redundant monitoring data sent by multiple slave devices. The target sensors transmit the processed data to the cloud background. The cloud background sends instructions to the sensor group through the target sensors.

[0084] It should be noted that each sensor group can correspond to different working modes, for example, the working mode of the sensor group corresponding to the temperature sensor can be the center mode, and the working mode of the sensor group corresponding to the humidity sensor can be the centerless mode.

[0085] In some embodiments, after determining the target sensor corresponding to the sensor group, the target sensor is controlled to send broadcast information to the remaining sensors in the sensor group, and the broadcast information includes the identity information and address information of the target sensor. Thus, the remaining sensors in the sensor group can determine the target sensor.

[0086] The identity information of the target sensor can be the ID information of the target sensor, which is used to make the slave server of the sensor group determine the identity of the target sensor; and the address information of the target sensor can be the communication address of the target sensor, which is used to make the slave server of the sensor group determine the address of the target sensor.

[0087] Specifically, after the target sensor is determined, the target sensor broadcasts a message to the sensor group, indicating that it is the identity of the sensor group, and broadcasts the address of the target sensor to the slave server, so that the slave server can send the collected environmental data to the target sensor according to the address of the target sensor.

[0088] S104, control the sensor in the sensor group to collect environmental data, and send the environmental data collected by each sensor to the target sensor through the distributed soft bus, so that the target sensor sends the environmental data to the server through the distributed soft bus.

[0089] Among them, since the target sensor is the sensor with the best device performance, in the center mode, the target sensor can collect the environmental data collected by the slave sensor in the sensor group, and the target sensor sends the collected environmental data to the server through the distributed soft bus. The environmental data can include temperature data, humidity data, etc.

[0090] In some embodiments, after the environmental data collected by each sensor is sent to the target sensor through the distributed soft bus, the target sensor performs data fusion on the environmental data to obtain target environmental data, so that the target sensor sends the target environmental data to the server through the distributed soft bus. In this way, the target sensor can preliminarily screen the environmental data, avoid sending multiple redundant environmental data to the server, improve the utilization rate of the target sensor, and reduce the computational burden of the server.

[0091] Among them, the target environmental data is the environmental data after data fusion, and the redundant monitoring data sent by multiple slave devices can be eliminated.

[0092] Specifically, the target sensor performs data screening on the environmental data, so as to screen the same type of environmental data, and performs data fusion on the same type of environmental data, so as to obtain target environmental data, so that the target sensor sends the target environmental data to the server through the distributed soft bus.

[0093] For example, the target sensor receives the temperature data of sensor a for region A, and also receives the temperature data of sensor b for region A. At this time, sensor a and sensor b are both collecting temperature data for region A, so the temperature data of sensor a for region A and the temperature data of sensor b for region A can be fused, such as by taking the average value, taking the median value, etc., so as to obtain target environmental data.

[0094] For example, after receiving the environmental data sent from the sensor, the target sensor stores the environmental data into a historical data list, and after receiving other environmental data sent from the sensor next time, the target sensor compares the received environmental data with the historical data list, discards the same part, and only reports the different part, and the cycle is repeated.

[0095] In S105, if the working mode of the sensor group is the non-central mode, the sensors in the sensor group are controlled to collect environmental data, and the environmental data is sent to the server through the distributed soft bus.

[0096] Specifically, when the sensor group works in the non-central mode, each sensor is in an equal position. The sensor with the best communication quality can undertake the communication role of the sensor group and the cloud background. In this mode, data fusion is not performed, and the original collected environmental data is transmitted to the cloud background through the distributed soft bus. Each sensor can also directly communicate with the cloud background through the distributed soft bus, so that the sensor can directly communicate with the cloud background without passing through the sensor with the best communication quality.

[0097] The application provides a control method of a sensor system. The sensor cluster is divided into multiple sensor groups according to the types of the sensors, and the working mode of the sensor group is determined according to the working requirements of the sensors. If the working mode of the sensor group is the central mode, the target sensor corresponding to the sensor group is determined, and the sensors in the sensor group are controlled to collect environmental data, and the collected environmental data is sent to the server through the target sensor through the distributed soft bus. If the working mode of the sensor group is the non-central mode, the sensors in the sensor group are controlled to collect environmental data, and the environmental data is sent to the server through the distributed soft bus.
