[0059] At present, building control systems mostly adopt a master-slave communication architecture, which uses a central controller as the core node and is connected to building equipment through serial bus communication. The central controller controls the building equipment through the serial bus.

[0060] However, when the central controller goes down due to hardware failure, software anomaly or network attack, the central controller will be unable to control the building equipment, resulting in failure of building equipment control.

[0061] To address the above-mentioned issues, embodiments of the present application provide a building equipment control method, sensor device, building control system, and medium. These methods obtain a target control instruction, which is generated by a sensor device based on environmental data collected from a target area. The target control instruction is used to control a first target building device corresponding to the target area among multiple building devices. A first target controller is determined based on a device weight table and the first target building device. The device weight table is used to characterize the control weight of each of the multiple controllers over each of the multiple building devices. The first target controller is the controller with the greatest control weight over the first target building device among the multiple controllers. The target control instruction is sent to the first target controller, causing the first target controller to control the first target building device. The device weight table can be used to characterize the topological network connection relationship between multiple building devices and multiple controllers. During the process of controlling the building devices, a target controller for the target building device is dynamically allocated based on the topological network connection relationship between the multiple building devices and the multiple controllers. The target building device is controlled based on the target controller. This can prevent building device control failures caused by master-slave communication between the controller and the building device and controller downtime, thereby improving the success rate of controlling the building devices.

[0062] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

The building control system may include a sensor device 100, a controller 200 and a building device 300. The controller 200 is connected to the sensor device 100 and the building device 300 through a bus, and exchanges data with the sensor device 100 and the building device 300 through the bus.

[0064] The number of sensor devices 100 may be one or more, and each sensor device 100 may be used to collect environmental data of an area of a building.

[0065] The sensor device 100 may be any one of a light sensor, a temperature sensor, or a smoke sensor, and the environmental data may be any one of the ambient light intensity, ambient temperature, or ambient smoke concentration, which is not limited here.

[0066] The number of the controller 200 may be one or more. Each controller 200 may be used to connect to and control at least one building device 300. The controller 200 is connected to the sensor device 100 via a bus.

[0067] The controller 200 can be any one of a lighting controller, an air conditioning controller, a fire controller, etc., which is not limited here.

[0068] The building equipment 300 may be any one of lighting equipment, air conditioning, elevator or fire-fighting equipment, etc., which is not limited here.

[0069] See also Figure 2 , which shows a flow chart of a control method for building equipment provided by an embodiment of the present application. In a specific embodiment, the control method for building equipment can be applied to Figure 1 The sensor device 100 in the building control system shown in FIG. 1 is taken as an example below. Figure 2 The process shown in FIG. 1 is described in detail. The building equipment control method may include the following steps 110 to 130 .

[0070] Step 110: Obtain target control instructions.

[0071] In an embodiment of the present application, the sensor device can obtain a target control instruction, which can be generated by the sensor device based on the environmental data collected from the target area. The target control instruction can be used to control the first target building device corresponding to the target area among multiple building devices.

[0072] The first target building equipment may be any one of lighting equipment, air conditioning or fire-fighting equipment, and the target control instruction may be any one of lighting control instruction, temperature adjustment instruction or fire-fighting control instruction, which is not limited here.

[0073] Specifically, the sensor device can collect environmental data of the target area and determine whether the target area is in a normal state based on the environmental data. When the target area is determined to be in an abnormal state based on the environmental data, a target control instruction is generated, thereby automatically triggering the control of building equipment when the target area is monitored to be in an abnormal state. There is no need for the user to manually trigger the control of the building equipment, thereby improving the user experience in the process of controlling the building equipment.

[0074] When the environmental data is within the environmental data threshold range, it is determined that the target area is in a normal state; when the environmental data is outside the environmental data threshold range, it is determined that the target area is in an abnormal state.

[0075] Among them, the environmental data threshold range can be used to represent the environmental data range of the target area in a normal state. The environmental data threshold range can be an environmental data range pre-set by the user, or it can be an environmental data range automatically generated by the sensor equipment based on the process of multiple controls on building equipment, etc., which is not limited here.

[0076] In some embodiments, the sensor device may be a light sensor, the environmental data may be the ambient light intensity, the environmental data threshold range may be the ambient light intensity threshold, the first target building device may be a lighting device, the target area may include a first area corresponding to the lighting device, and the target control instruction may be a lighting control instruction for controlling the lighting device.

[0077] The light sensor can collect the ambient light intensity of the first area, and determine whether the first area is in a normal state according to the ambient light intensity, and generate a lighting control instruction when it is determined that the first area is in an abnormal state according to the ambient light intensity.

[0078] When the ambient light intensity is greater than or equal to the ambient light intensity threshold, it is determined that the first area is in a normal state; when the ambient light intensity is less than the ambient light intensity threshold, it is determined that the first area is in an abnormal state.

[0079] Among them, the ambient light intensity threshold can be used to characterize the minimum ambient light intensity when the first area is in a normal state. The ambient light intensity threshold can be the ambient light intensity pre-set by the user, or it can be the ambient light intensity automatically generated by the sensor device based on the process of multiple controls on building equipment, etc., which is not limited here.

[0080] In some embodiments, the sensor device may be a temperature sensor, the environmental data may be the ambient temperature, the environmental data threshold range may be the ambient temperature threshold range, the first target building equipment may be an air conditioner, the target area may include a second area corresponding to the air conditioner, and the target control instruction may be a temperature adjustment instruction for controlling the air conditioner.

[0081] The temperature sensor may collect the ambient temperature of the second area, and determine whether the second area is in a normal state according to the ambient temperature, and generate a temperature adjustment instruction when it is determined that the second area is in an abnormal state according to the ambient temperature.

[0082] When the ambient temperature is within the ambient temperature threshold range, it is determined that the second area is in a normal state; when the ambient temperature is outside the ambient temperature threshold range, it is determined that the second area is in an abnormal state.

[0083] Among them, the ambient temperature threshold range can be used to represent the ambient temperature range in which the second area is in a normal state. The ambient temperature threshold range can be an ambient temperature range pre-set by the user, or it can be an ambient temperature range automatically generated by the sensor device based on the process of multiple controls on building equipment, etc., which is not limited here.

[0084] The temperature adjustment instruction may include a first temperature adjustment instruction for controlling the air conditioner to heat, and a second temperature adjustment instruction for controlling the air conditioner to cool.

[0085] When the ambient temperature is lower than the lower limit of the ambient temperature threshold range, a first temperature adjustment instruction is generated; when the ambient temperature is higher than the upper limit of the ambient temperature threshold range, a second temperature adjustment instruction is generated.

[0086] In some embodiments, the sensor device may be a smoke sensor, the environmental data may be the environmental smoke concentration, the environmental data threshold range may be the environmental smoke concentration threshold, the first target building equipment may be fire-fighting equipment, the target area may include a third area corresponding to the fire-fighting equipment, and the target control instruction may be a fire-fighting control instruction for controlling the fire-fighting equipment.

[0087] The smoke sensor can collect the ambient smoke concentration of the third area, and determine whether the third area is in a normal state according to the ambient smoke concentration, and generate a fire control instruction when the third area is determined to be in an abnormal state according to the ambient smoke concentration.

[0088] When the ambient smoke concentration is less than or equal to the ambient smoke concentration threshold, it is determined that the third area is in a normal state; when the ambient smoke concentration is greater than the ambient smoke concentration threshold, it is determined that the third area is in an abnormal state.

[0089] Among them, the ambient smoke concentration threshold can be used to represent the maximum ambient smoke concentration of the third area in a normal state. The ambient smoke concentration threshold can be the ambient smoke concentration pre-set by the user, or it can be the ambient smoke concentration automatically generated by the sensor device based on the process of multiple controls on building equipment, etc., which is not limited here.

[0090] Step 120: Determine a first target controller based on the device weight table and the first target building device.

[0091] In the embodiment of the present application, the sensor device may determine the first target controller based on the device weight table and the first target building device.

[0092] The device weight table may be used to characterize the control weight of each of the multiple controllers over each of the multiple building devices, that is, the device weight table may be used to characterize the topological network connection relationship between the multiple building devices and the multiple controllers.

[0093] The first target controller may be the controller with the greatest control weight for the first target building equipment among the multiple controllers. For example, the first target controller may be any one of a lighting controller, an air conditioning controller, or a fire controller, etc., which is not limited here.

[0094] The sensor device can determine the control weights of each controller on the first target building device according to the device weight table, obtain multiple control weights, and determine the controller corresponding to the maximum control weight among the multiple control weights as the first target controller.

[0095] In an application scenario, the multiple building devices may include building device 1, building device 2, and building device 3, and the multiple controllers may include controller 1, controller 2, and controller 3.

[0096] The device weight table can be shown as Table 1, where the control weight of controller 1 on building equipment 1 is control weight 1, the control weight of controller 2 on building equipment 1 is control weight 2, and the control weight of controller 3 on building equipment 1 is control weight 3; the control weight of controller 1 on building equipment 2 is control weight 4, the control weight of controller 2 on building equipment 2 is control weight 5, and the control weight of controller 3 on building equipment 2 is control weight 6; the control weight of controller 1 on building equipment 3 is control weight 7, the control weight of controller 2 on building equipment 3 is control weight 8, and the control weight of controller 3 on building equipment 3 is control weight 9.

[0097] Table 1

[0098]

[0099] It should be noted that the categories of controllers, building equipment, and control weights are not limited to those shown in Table 1, and can be specifically set according to actual needs.

[0100] Step 130: Send a target control instruction to the first target controller, so that the first target controller controls the first target building equipment.

[0101] In an embodiment of the present application, the sensor device can send a target control instruction to the first target controller based on the bus. The first target controller receives and responds to the target control instruction to control the first target device. In the process of controlling the building equipment, the target controller of the target building equipment is dynamically allocated according to the topological network connection relationship between multiple building equipment and multiple controllers, and the target building equipment is controlled based on the target controller. This can suppress the master-slave communication connection between the controller and the building equipment and the failure of the building equipment control caused by the controller downtime, which is beneficial to improving the control success rate of the building equipment.

[0102] In some embodiments, the sensor device may be a light sensor, the first target building device may be a lighting device, the target control instruction may be a lighting control instruction for controlling the lighting device, and the first target controller may be a lighting controller.

[0103] The light sensor may send a lighting control instruction to the lighting controller. The lighting controller receives and responds to the lighting control instruction to control the lighting device, for example, to control the lighting device to illuminate.

[0104] In some embodiments, the sensor device may be a temperature sensor, the first target building device may be an air conditioner, the target control instruction may be a temperature adjustment instruction for controlling the air conditioner, and the first target controller may be an air conditioner controller.

[0105] The temperature sensor can send a temperature adjustment instruction to the air conditioner controller. The air conditioner controller receives and responds to the temperature adjustment instruction to control the air conditioner, for example, to control the air conditioner to cool or heat.

[0106] When the temperature adjustment instruction is the first temperature adjustment instruction, the air conditioner is controlled to heat; when the temperature adjustment instruction is the second temperature adjustment instruction, the air conditioner is controlled to cool.

[0107] In some embodiments, the sensor device may be a smoke sensor, the first target building device may be a fire protection device, the target control instruction may be a fire protection control instruction for controlling the fire protection device, and the first target controller may be a fire protection controller.

[0108] The smoke sensor can send a fire control instruction to the fire controller. The fire controller receives and responds to the fire control instruction and controls the fire equipment, for example, controlling the fire equipment to start fire extinguishing.

[0109] In some embodiments, the target control instruction may include multiple sub-control instructions, the target controller may include multiple sub-controllers, the first target building equipment may include multiple sub-building equipment, and one sub-control instruction may be used to instruct a sub-controller to control at least one sub-building equipment.

[0110] The sensor device can determine the priority order of multiple sub-control instructions, and send the multiple sub-control instructions to multiple sub-controllers in sequence according to the priority order at preset time intervals based on the bus. Each sub-controller receives and responds to a sub-control instruction, and controls at least one sub-building device connected to the sub-controller. Sending multiple sub-control instructions in sequence according to the priority order of multiple sub-control instructions can suppress the direct sending of multiple sub-control instructions, which may cause network congestion and lead to the failure of sending some sub-control instructions, and is conducive to improving the success rate of multiple sub-control instructions.

[0111] The priority order of the sub-control instructions can be used to represent the urgency of the sub-control instructions. The higher the priority order, the higher the urgency of the sub-control instruction.

[0112] The preset duration may be a duration pre-set by the user, or a duration automatically generated by the sensor device based on a process of controlling the building equipment multiple times, etc., and is not limited here.

[0113] The sensor device can calculate a hash value for each sub-building device to obtain multiple hash values, and assign each hash value to a control level value of a corresponding sub-control instruction to obtain multiple control level values, and determine the order of the multiple control level values from large to small as the priority order. The priority order of the corresponding instructions is determined according to the size order of the hash values of the building devices, thereby improving the accuracy of the priority order.

[0114] The sensor device can perform MurmurHash3 operation on the device information of each sub-building device to obtain a corresponding hash value.

[0115] Device information may include device ID, timestamp, and random number. The random number is a 16-bit value randomly generated by the corresponding sub-building device, and the hash value is a 32-bit value.

[0116] As an example, the sub-building devices include device A and device B. The device ID of device A is DEV-001, the timestamp of device A is 1717024000123, and the random number of device A is 0x3A7F.

[0117] The device ID of device B is DEV-002, the timestamp of device B is 1717024000123, and the random number of device B is 0x7E29.

[0118] Perform MurmurHash3 on the device information DEV-001+1717024000123+0x3A7F of device A, and the corresponding hash value is 0x58D23B1A.

[0119] Perform MurmurHash3 on the device information DEV-002+1717024000123+0x7E29 of device B, and the corresponding hash value is 0x62F891C4.

[0120] The solution provided in the present application obtains a target control instruction, which is generated by a sensor device based on environmental data collected from a target area. The target control instruction is used to control a first target building device corresponding to a target area among multiple building devices, and a first target controller is determined based on a device weight table and the first target building device. The device weight table is used to characterize the control weight of each controller among the multiple controllers over each building device among the multiple building devices. The first target controller is the controller with the largest control weight over the first target building device among the multiple controllers, and the target control instruction is sent to the first target controller so that the first target controller controls the first target building device. The device weight table can be used to characterize the topological network connection relationship between multiple building devices and multiple controllers. In the process of controlling the building equipment, the target controller of the target building equipment is dynamically allocated according to the topological network connection relationship between the multiple building devices and the multiple controllers, and the target building equipment is controlled based on the target controller. This can suppress the master-slave communication connection between the controller and the building equipment and the failure of the controller to control the building equipment, which is beneficial to improving the control success rate of the building equipment.

[0121] See also Figure 3 , which shows a flow chart of a control method for building equipment provided by another embodiment of the present application. In a specific embodiment, the control method for building equipment can be applied to Figure 1 The sensor device 100 in the building control system shown in FIG. 1 is taken as an example below. Figure 3 The process shown in FIG. 1 is described in detail. The building equipment control method may include the following steps 210 to 250.

[0122] Step 210: Receive broadcast information from each controller to obtain multiple broadcast information.

[0123] In this embodiment, each controller may broadcast one broadcast message, and the sensor device receives the broadcast message of each controller to obtain multiple broadcast messages.

[0124] Each broadcast information may include location information and signal strength of each building device connected to the corresponding controller relative to the corresponding controller.

[0125] The location information may include a distance index. A higher distance index of a building device relative to a corresponding controller indicates that the building device is closer to the corresponding controller.

[0126] Step 220: Construct a device weight table according to the plurality of broadcast information.

[0127] In this embodiment, the sensor device can perform weighted summation based on the position information and signal strength of each building device connected to each controller relative to the controller, as well as the preset position weight and signal weight, to obtain the control weight of each controller over each building device, and generate a corresponding weight table based on the control weight of each controller over each building device. Based on the position information and signal strength of the building device relative to the controller, the control weight of the controller over the building device is calculated, thereby improving the accuracy of the control weight.

[0128] Among them, the sensor device can calculate the weighted sum of the distance index, signal strength, preset location weight and signal weight of each building device relative to the connected controller to obtain the control weight of the controller for each building device.

[0129] In an application scenario, the multiple building devices may include building device 1, building device 2, and building device 3, the multiple controllers may include controller 1, controller 2, and controller 3, the preset location weight is 0.8, and the preset signal weight is 0.2.

[0130] As shown in Table 2, the location information of building equipment 1 relative to controller 1 is a distance index of 90, and the signal strength of building equipment 1 relative to controller 1 is 100 db. Therefore, the control weight of controller 1 on building equipment 1 is 90×0.8+100×0.2=92.

[0131] The location information of building equipment 1 relative to controller 2 is a distance index of 80, and the signal strength of building equipment 1 relative to controller 2 is 85 db. Therefore, the control weight of controller 2 on building equipment 1 is 80×0.8+85×0.2=81.

[0132] The location information of the building equipment 1 relative to the controller 3 is a distance index of 60, and the signal strength of the building equipment 1 relative to the controller 3 is 60 db. Then the control weight of the controller 3 on the building equipment 1 is 60×0.8+60×0.2=60.

[0133] The location information of the building equipment 2 relative to the controller 1 is a distance index of 85, and the signal strength of the building equipment 2 relative to the controller 1 is 90 dB. Therefore, the control weight of the controller 1 on the building equipment 2 is 85×0.8+90×0.2=86.

[0134] The location information of the building equipment 2 relative to the controller 2 is a distance index of 70, and the signal strength of the building equipment 2 relative to the controller 2 is 70 db. Then the control weight of the controller 2 on the building equipment 2 is 70×0.8+70×0.2=70.

[0135] The location information of the building equipment 2 relative to the controller 3 is a distance index of 50, and the signal strength of the building equipment 2 relative to the controller 3 is 50 db. Then the control weight of the controller 3 on the building equipment 2 is 50×0.8+50×0.2=50.

[0136] The location information of the building equipment 3 relative to the controller 1 is a distance index of 70, and the signal strength of the building equipment 3 relative to the controller 1 is 80 dB. Therefore, the control weight of the controller 1 on the building equipment 3 is 70×0.8+80×0.2=72.

[0137] The location information of the building equipment 3 relative to the controller 2 is a distance index of 50, and the signal strength of the building equipment 3 relative to the controller 2 is 60 dB. Then, the control weight of the controller 2 on the building equipment 3 is 50×0.8+60×0.2=52.

[0138] The location information of the building equipment 3 relative to the controller 3 is a distance index of 30, and the signal strength of the building equipment 3 relative to the controller 3 is 20 db. Then the control weight of the controller 3 on the building equipment 3 is 30×0.8+20×0.2=28.

[0140]

[0141] It should be noted that the distance index, signal strength, preset location weight, and preset signal weight of the building equipment relative to the controller are not limited to those shown in Table 2, and can be set according to actual needs.

[0142] In some embodiments, after the sensor device constructs a device weight table based on multiple broadcast information, it can receive updated broadcast information of a second target controller among multiple controllers. The updated broadcast information may include the current device position and current signal strength of the second target building device connected to the second target controller relative to the second target controller. The updated broadcast information can be generated based on the second target controller when it monitors that the device position and / or signal strength of the second target building device have changed, and the device weight table is updated based on the updated broadcast information. Updating the device weight table based on changes in the device position and / or signal strength of the building device is conducive to improving the accuracy of subsequent determination of the target controller based on the device weight table.

[0143] Step 230: Obtain target control instructions.

[0144] In this embodiment, step 230 may refer to the contents of the corresponding steps in the aforementioned embodiments, which will not be repeated here.

[0145] Step 240: Determine a first target controller based on the device weight table and the first target building device.

[0146] In this embodiment, the sensor device can perform weighted summation based on the position information and signal strength of the first target building device relative to the connected controller, as well as the preset position weight and signal weight, to obtain the control weight of each controller on the first target building device, and determine the controller with the largest control weight as the first target controller. Selecting the controller with the largest control weight as the target controller is conducive to improving the control success rate of the target building device based on the target controller.

[0147] Step 250: Send a target control instruction to the first target controller, so that the first target controller controls the first target building equipment.

[0148] In this embodiment, step 250 may refer to the contents of the corresponding steps in the aforementioned embodiments, which will not be repeated here.

[0149] The solution provided in this embodiment receives broadcast information from each controller to obtain multiple broadcast information, and constructs a device weight table based on the multiple broadcast information, obtains target control instructions, and determines the first target controller based on the device weight table and the first target building equipment, and sends the target control instructions to the first target controller, so that the first target controller controls the first target building equipment. The device weight table can be used to characterize the topological network connection relationship between multiple building equipment and multiple controllers. In the process of controlling the building equipment, the target controller of the target building equipment is dynamically allocated according to the topological network connection relationship between the multiple building equipment and the multiple controllers, and the target building equipment is controlled based on the target controller. This can suppress the master-slave communication connection between the controller and the building equipment and the failure of the building equipment control caused by the controller downtime, which is beneficial to improving the control success rate of the building equipment.

[0150] Furthermore, the control weight of the controller over the building equipment is calculated based on the location information of the building equipment relative to the controller and the signal strength, thereby improving the accuracy of the control weight.

[0151] See also Figure 4 , which shows a sensor device 100 provided in one embodiment of the present application. The sensor device 100 may include a collection module 101 and a control module 102 . The collection module 101 may be connected to the control module 102 .

[0152] The acquisition module 101 can be used to collect environmental data of the target area; the control module 102 can be used to obtain target control instructions. The target control instructions can be generated by the control module based on the environmental data sent by the acquisition module. The target control instructions can be used to control the first target building equipment corresponding to the target area among multiple building equipment, and determine the first target controller based on the equipment weight table and the first target building equipment. The equipment weight table can be used to characterize the control weight of each controller among the multiple controllers on each building equipment among the multiple building equipment. The first target controller can be the controller with the largest control weight for the first target building equipment among the multiple controllers, and the target control instruction is sent to the first target controller so that the first target controller controls the first target building equipment.

[0153] In some embodiments, the control module 102 can also be used to receive broadcast information from each controller before obtaining the target control instruction, and obtain multiple broadcast information. Each broadcast information may include the location information and signal strength of each building device connected to the corresponding controller relative to the corresponding controller, and construct a device weight table based on the multiple broadcast information. The control weight of the controller on the building device can be obtained based on the corresponding location information and signal strength representation.

[0154] In some embodiments, the control module 102 can also be used to perform weighted summation based on the location information and signal strength of the first target building device relative to the connected controller, as well as the preset location weight and signal weight, to obtain the control weight of each controller on the first target building device, and determine the controller with the largest control weight as the first target controller.

[0155] In some embodiments, the control module 102 can also be used to receive updated broadcast information of a second target controller among multiple controllers after constructing a device weight table based on multiple broadcast information. The updated broadcast information may include the current device position and current signal strength of the second target building device connected to the second target controller relative to the second target controller. The updated broadcast information is generated based on the second target controller when it monitors changes in the device position and / or signal strength of the second target building device, and the device weight table is updated based on the updated broadcast information.

[0156] In some embodiments, the target control instruction may include multiple sub-control instructions, the target controller may include multiple sub-controllers, the first target building equipment may include multiple sub-building equipment, and one sub-control instruction may be used to instruct a sub-controller to control at least one sub-building equipment; the control module 102 may also be used to determine the priority order of the multiple sub-control instructions, and send the multiple sub-control instructions to the multiple sub-controllers in sequence at preset intervals according to the priority order, so that each sub-controller controls at least one sub-building equipment.

[0157] In some embodiments, the control module 102 can also be used to calculate a hash value for each sub-building device to obtain multiple hash values, and assign each hash value to a control level value of a corresponding sub-control instruction to obtain multiple control level values, and determine the priority order of the multiple control level values from large to small.

[0158] In some embodiments, the control module 102 may also be configured to collect environmental data of the target area, and generate a target control instruction when it is determined based on the environmental data that the target area is in an abnormal state.

[0159] The solution provided in this embodiment obtains a target control instruction. The target control instruction is generated by a sensor device based on environmental data collected from a target area. The target control instruction is used to control a first target building device corresponding to the target area among multiple building devices. A first target controller is determined based on a device weight table and the first target building device. The device weight table is used to represent the control weight of each of the multiple controllers over each of the multiple building devices. The first target controller is the controller with the greatest control weight over the first target building device among the multiple controllers. The target control instruction is sent to the first target controller so that the first target controller controls the first target building device. The device weight table can be used to represent the topological network connection relationship between multiple building devices and multiple controllers. During the process of controlling the building devices, the target controller of the target building device is dynamically allocated based on the topological network connection relationship between the multiple building devices and the multiple controllers. The target building device is controlled based on the target controller. This can prevent building device control failure caused by master-slave communication between the controller and the building device and controller downtime, thereby improving the control success rate of the building device.
