Description

Technical Field

[0001] This application relates to the field of smart campus system control technology, and in particular to a control method, controller and smart campus system for a smart campus system. Background Technology

[0002] With the continuous development of technology and the increasing emphasis on education, more and more smart devices are being used in schools, forming smart campuses. In particular, the intelligentization of desks and chairs, through personalized adjustments, can improve students' learning comfort and enhance teaching effectiveness.

[0003] The smart campus comprises multiple teaching buildings, each containing multiple classrooms, and each classroom equipped with multiple sets of smart desks and chairs. Each teaching building is equipped with a gateway to control the smart desks and chairs within that building. The management platform can control the activation and operation of each smart desk and chair through the gateway.

[0004] In practical applications, the total power consumption of smart desks and chairs in each teaching building is approximately 67,500W. If smart desks and chairs in multiple teaching buildings are activated simultaneously, it may cause the circuit to operate under instantaneous overload, leading to circuit damage and potentially causing safety accidents. Summary of the Invention

[0005] This application provides a control method, controller, and smart campus system for a smart campus system, in order to solve the problem of instantaneous overload and damage to circuits when smart desks and chairs in multiple teaching buildings are started simultaneously.

[0006] In the first aspect, this application provides a control method for a smart campus system. The smart campus system includes a management gateway and multiple teaching building gateways. Each teaching building in the campus is equipped with a teaching building gateway, which is used to control the smart desks and chairs in that teaching building.

[0007] Control methods applied to gateways include:

[0008] Detect whether a group control command has been received, which is used to control the smart desks and chairs to start.

[0009] Upon receiving a group control command, obtain the startup power of the smart desks and chairs in each teaching building;

[0010] The startup order of the smart desks and chairs in each teaching building is determined based on the startup power. The group control command is then sent to the teaching building gateway of each teaching building in sequence according to the startup order, so that the smart desks and chairs in each teaching building can be started.

[0011] In one possible implementation, the startup sequence of the smart desks and chairs in each teaching building is determined based on the startup power, including:

[0012] Sort the smart desks and chairs in ascending order of starting power, and use this ranking as the starting order for each teaching building; or,

[0013] The smart desks and chairs in each teaching building are sorted from highest to lowest starting power, and this sorting result is used as the starting order for each building.

[0014] In one possible implementation, before determining whether a group control command has been received, the method further includes:

[0015] Encode all gateways in the teaching buildings;

[0016] Accordingly, the startup sequence for the smart desks and chairs in each teaching building is determined based on the startup power, including:

[0017] Determine if there are any teaching buildings with the same starting power;

[0018] If present, the startup order of the smart desks and chairs in multiple teaching buildings with the same power will be determined according to the coding order of the teaching building gateway.

[0019] In one possible implementation, determining whether there are teaching buildings with the same starting power includes:

[0020] For any two teaching buildings, if the absolute value of the difference in starting power between the two teaching buildings is less than a preset value, then the starting power of the two teaching buildings is determined to be the same.

[0021] In one possible implementation, the group control commands are sent sequentially to the teaching building gateways of each teaching building according to the startup order, including:

[0022] Based on the startup sequence, a group control command is sent to the current teaching building gateway, and after a preset time, a group control command is sent to the next teaching building gateway.

[0023] In one possible implementation, the preset duration is determined based on the startup power of the smart desks and chairs in the teaching building where the current teaching building gateway is located and the startup power of the smart desks and chairs in the teaching building where the next teaching building gateway is located.

[0024] Secondly, this application provides another control method for a smart campus system. The smart campus system includes a management gateway, multiple teaching building gateways and multiple floor sub-gateways. Each teaching building in the campus is equipped with a teaching building gateway and multiple floor sub-gateways. The teaching building gateway is used to control the smart desks and chairs in the teaching building through the multiple floor sub-gateways in the teaching building.

[0025] The control method is applied to the gateway of each teaching building, including:

[0026] Encode each floor's sub-gateway in the teaching building;

[0027] Upon receiving a group control command from the management gateway, the command is sequentially sent to each floor sub-gateway in the teaching building according to the coding order of each floor sub-gateway, so as to activate the smart desks and chairs in the teaching building.

[0028] Thirdly, this application provides a control device for a smart campus system. The smart campus system includes a management gateway and multiple teaching building gateways. Each teaching building in the campus is equipped with a teaching building gateway, which is used to control the smart desks and chairs in that teaching building.

[0029] This control device is used to manage the gateway and includes:

[0030] The detection module is used to detect whether a group control command has been received, which is used to control the smart desks and chairs to start.

[0031] The first control module is used to obtain the starting power of the smart desks and chairs in each teaching building when a group control command is received;

[0032] The second control module is used to determine the startup order of the smart desks and chairs in each teaching building according to the startup power, and to send the group control command to the teaching building gateway of each teaching building in sequence according to the startup order, so as to start the smart desks and chairs in each teaching building.

[0033] Fourthly, this application provides another control device for a smart campus system. The smart campus system includes a management gateway, multiple teaching building gateways, and multiple floor sub-gateways. Each teaching building in the campus is equipped with a teaching building gateway and multiple floor sub-gateways. The teaching building gateway is used to control the smart desks and chairs in the teaching building through the multiple floor sub-gateways in the teaching building.

[0034] This control device is applied to the gateway of each teaching building, including:

[0035] The sub-gateway encoding module is used to encode the sub-gateways on each floor of the teaching building;

[0036] The third control module is used to send the group control command to each floor sub-gateway in the teaching building in sequence according to the coding order of each floor sub-gateway in the teaching building when it receives the group control command sent by the management gateway, so as to start the smart desks and chairs in the teaching building.

[0037] Fifthly, this application provides a controller, including a memory and a processor. The memory stores a computer program that can run on the processor. When the processor executes the computer program, it implements the steps of the control method of the smart campus system as described in the first aspect above or any possible implementation of the first aspect, or the steps of the control method of the smart campus system as described in the second aspect above.

[0038] Sixthly, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the control method for a smart campus system as described in the first aspect above or any possible implementation of the first aspect, or the steps of the control method for a smart campus system as described in the second aspect above.

[0039] This application provides a control method, controller, and smart campus system for a smart campus system. The campus system includes a management gateway and multiple teaching building gateways. The control method is applied to the management gateway. When the management gateway receives a group control command to start the smart desks and chairs in the campus, it determines the starting sequence according to the starting power of each teaching building to delay the starting of the smart desks and chairs in each teaching building. This avoids excessive load on the campus power supply lines when starting simultaneously. By delaying the starting, the instantaneous power is reduced while ensuring the reliability of the smart desks and chairs starting, thus avoiding line damage and improving the reliability and security of the campus power supply.

[0046] Figure 6 This is a schematic diagram of the controller provided in an embodiment of this application. Detailed Implementation

[0047] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0048] Figure 1 This is a schematic diagram of the structure of a smart campus system provided in an embodiment of this application, such as... Figure 1 As shown, the smart campus system may include a management gateway and multiple teaching building gateways. Each teaching building on campus is equipped with a teaching building gateway, which is used to control the smart desks and chairs in that teaching building.

[0049] like Figure 1 As shown, the management gateway can receive external control commands, such as those from the management platform, and then distribute these commands to the N teaching building gateways. These N teaching building gateways are the subordinate sub-gateways of the management gateway.

[0050] The management platform can communicate with the management gateway, the management gateway with N teaching building gateways, and each of the N teaching building gateways and their respective smart desks and chairs via wired or wireless protocols. Wired communication methods can include Ethernet cables, CAN bus, or RS-485 bus. Wireless communication methods can include WiFi, 4G / 5G SIM cards, NB-IoT, Zigbee, LoRaWAN, or Bluetooth. The specific deployment can be chosen based on the actual situation.

[0051] In the embodiments of this application, each teaching building on campus is equipped with a corresponding teaching building gateway. This gateway can control all the smart desks and chairs in that building, specifically controlling their activation or deactivation. The smart desks and chairs include smart desks and smart seats.

[0052] In practical applications, the minimum power consumption of a single smart desk / smart chair is 30W. Assuming a teaching building has 25 classrooms and each classroom is equipped with 45 sets of smart desks and chairs, the total power consumption of smart desks and chairs in a teaching building is approximately 25*45*2*30=67500W. A campus typically includes multiple teaching buildings, and power consumption of tens of thousands of watts poses a significant challenge to the laying of campus power lines and the management of the power supply system.

[0053] To avoid the above problems, this application proposes a control method for a smart campus system. By determining the startup sequence based on the startup power of each teaching building, the smart desks and chairs in each teaching building are started sequentially with a delay, thus avoiding power overload caused by simultaneous startup.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0055] See Figure 2 The diagram illustrates a flowchart of the implementation of a control method for a smart campus system provided in an embodiment of this application. Figure 2 As shown, a control method for a smart campus system is provided. This control method is applied to the management gateway in the smart campus system and may include steps S101 to S103.

[0056] S101, detect whether a group control command has been received. The group control command is used to control the smart desks and chairs to start.

[0057] In the embodiments of this application, the management platform can send group control commands to the management gateway. These commands are used to control the activation of smart desks and chairs. The group control commands can include desk group control commands and chair group control commands; the desk group control commands control the activation of smart desks, and the chair group control commands control the activation of smart chairs.

[0058] Optionally, the management platform can send a group control command to the management gateway upon receiving an external start signal. Alternatively, it can send the group control command to the management gateway within a preset time period, where the preset time period can be a preset school start time, such as 7:30-8:00 or 7:00-7:30, and the specific time period can be selected according to the actual situation.

[0059] For example, the management platform can be a campus management computer, a campus management terminal, or a handheld terminal.

[0060] Optionally, the management gateway can detect whether it has received group control commands in real time to improve the real-time response. Alternatively, it can only detect whether it has received group control commands within a preset time period, and not detect them in other time periods to reduce the power consumption of the management gateway.

[0061] In the embodiments of this application, the validity of a group control command can be detected by determining whether a group control command is received within a preset time period.

[0062] Specifically, if a group control command is received within a preset time period, the command is considered valid. If a group control command is received outside the preset time period, the command is considered invalid.

[0063] In the embodiments of this application, if a group control command is received outside of a preset time period, a prompt signal is output to indicate that the group control command is invalid. If a group control command is received again after the prompt signal is output, the group control command is determined to be valid. This secondary detection not only prevents the management platform from mistakenly sending group control commands but also serves as a prompt, allowing administrators to promptly monitor the working status of the management gateway.

[0064] S102, upon receiving a group control command, obtains the startup power of the smart desks and chairs in each teaching building.

[0065] In the embodiments of this application, the number of smart desks and chairs in each teaching building may change over time, such as increasing or decreasing. The management platform records the real-time number of smart desks and chairs in each teaching building, and the starting power required to activate the smart desks and chairs in each teaching building can be calculated based on the real-time number.

[0066] When the management gateway receives a valid group control command, it can obtain the startup power required to start the smart desks and chairs in each teaching building on campus.

[0067] Optionally, the management gateway can directly obtain the startup power required to activate the smart desks and chairs in each teaching building from the management platform. Alternatively, the management gateway can obtain the number of smart desks and chairs in each teaching building from the management platform and then calculate the startup power of the smart desks and chairs in each teaching building based on the number. Or, the management gateway can preset the startup power of the smart desks and chairs in each teaching building and directly retrieve the required startup power for each teaching building when it receives a group control command.

[0068] S103 determines the startup order of the smart desks and chairs in each teaching building based on the startup power, and sends the group control command to the teaching building gateway of each teaching building in sequence according to the startup order, so as to start the smart desks and chairs in each teaching building.

[0069] In the embodiments of this application, in order to avoid excessive instantaneous load caused by starting all smart desks and chairs at the same time, which could damage the power supply lines, the management gateway can determine the starting order based on the starting power of each teaching building.

[0070] In the embodiments of this application, the teaching building gateway can directly control the activation of smart desks and chairs in the corresponding teaching building, or the teaching building gateway can control the smart desks and chairs in the corresponding teaching building through its subordinate sub-gateways.

[0071] Optionally, the smart desks and chairs can be sorted from lowest to highest starting power, and this sorting result can be used as the starting order for each teaching building; or, they can be sorted from highest to lowest starting power, and this sorting result can be used as the starting order for each teaching building.

[0072] For example, the campus includes three teaching buildings, A, B, and C, with starting power denoted as P. A P B P C P A <P B <P C .

[0073] Based on the order of startup power from lowest to highest, the startup sequence for the three teaching buildings can be A→B→C. That is, the management gateway can first send a group control command to the gateway of teaching building A to start the smart desks and chairs in building A. Then, it can send a group control command to the gateway of teaching building B to start the smart desks and chairs in building B. Finally, it can send a group control command to the gateway of teaching building C to start the smart desks and chairs in building C.

[0074] Based on the order of startup power from highest to lowest, the startup sequence for the three teaching buildings can be C→B→A. That is, the management gateway can first send a group control command to the gateway of teaching building C to start the smart desks and chairs in building C. Then, it can send a group control command to the gateway of teaching building B to start the smart desks and chairs in building B. Finally, it can send a group control command to the gateway of teaching building A to start the smart desks and chairs in building A.

[0075] The management gateway sends group control commands sequentially to the teaching building gateways of each teaching building according to their power levels, thereby enabling staggered activation of smart desks and chairs in each teaching building. This avoids excessive instantaneous load on the campus power supply lines and ensures the reliability of the power supply.

[0076] In addition, when two or more teaching buildings have the same starting power, group control commands can be sent sequentially according to the teaching building number to avoid starting the smart desks and chairs of multiple teaching buildings at the same time, thereby improving the reliability of the power supply line.

[0077] This application embodiment determines the starting sequence based on the starting power of each teaching building when receiving a group control command to start the smart desks and chairs on campus. This delays the start of the smart desks and chairs in each teaching building, avoiding excessive load on the campus power supply lines when they start simultaneously. By delaying the start, the instantaneous power is reduced while ensuring the reliability of the smart desks and chairs, thus preventing line damage and improving the reliability and safety of the campus power supply.

[0078] In some embodiments of this application, before determining whether a group control command has been received, the control method further includes: encoding all teaching building gateways.

[0079] Optionally, the management gateway can pre-encode the building gateways in all teaching buildings on campus. The coding order can be the same as the building number, or the building gateways in each teaching building can be randomly coded, or the coding can be based on the historical startup power of each teaching building. The specific choice can be made according to the actual situation.

[0080] Accordingly, the startup sequence for the smart desks and chairs in each teaching building is determined based on the startup power, including:

[0081] Determine if there are any teaching buildings with the same starting power;

[0082] If present, the startup order of the smart desks and chairs in multiple teaching buildings with the same power will be determined according to the coding order of the teaching building gateway.

[0083] In the embodiments of this application, there may be teaching buildings with similar or identical startup power. For teaching buildings with similar startup power, the startup order of the smart desks and chairs in the same teaching building can be determined according to the coding order. The one with the earlier coding order will be started first, and the one with the later coding order will be started second.

[0084] For example, the campus includes four teaching buildings: A, B, C, and D, with starting power denoted as P. A P B P C P D P A <P B <P C =P D The gateway code for teaching building C is 3, and the gateway code for teaching building D is 4.

[0085] Based on the order of startup power from lowest to highest and the order of coding from lowest to highest, the startup sequence for the three teaching buildings can be A→B→C→D. That is, the management gateway can first send a group control command to the gateway of teaching building A to start the smart desks and chairs in building A. Then it can send a group control command to the gateway of teaching building B to start the smart desks and chairs in building B. Next, it can send a group control command to the gateway of teaching building C to start the smart desks and chairs in building C. Finally, it can send a group control command to the gateway of teaching building D to start the smart desks and chairs in building D.

[0086] In the embodiments of this application, for every two teaching buildings, if the absolute value of the difference in the starting power of the two teaching buildings is less than a preset value, then the starting power of the two teaching buildings is determined to be the same. The preset value can be determined based on a preset percentage of the average starting power of the two teaching buildings; for example, the preset value can be 0.5% of the average starting power of the two teaching buildings.

[0087] For example, the starting power of teaching building A is P. A =67500W, the starting power P of teaching building B B =67200W, the preset value is 0.5%*(67500+67200) / 2=336.75W.

[0088] Because of |P A -P B =300W < 336.75W, therefore the starting power of teaching building A and teaching building B can be considered to be the same.

[0089] This application embodiment determines whether the starting power of two teaching buildings is the same by dynamically setting preset values. The judgment result is more accurate and reliable, ensuring the orderly issuance of group control commands, avoiding damage to power supply lines caused by the simultaneous activation of smart desks and chairs in multiple teaching buildings, and improving the reliability of campus power supply.

[0090] In some embodiments of this application, the "sending the group control command sequentially to the teaching building gateway of each teaching building according to the startup order" in S103 above may include:

[0091] Based on the startup sequence, a group control command is sent to the current teaching building gateway, and after a preset time, a group control command is sent to the next teaching building gateway.

[0092] In the embodiments of this application, to ensure that the smart desks and chairs in each teaching building are activated at staggered times, the management gateway can set a delay in sending commands to the teaching building gateways of each teaching building. After sending a group control command to one teaching building gateway, a preset delay is set before sending the group control command to the next teaching building gateway.

[0093] The preset duration is the time required to ensure that the smart desks and chairs in each teaching building are fully activated.

[0094] For example, the campus includes three teaching buildings, A, B, and C, with starting power denoted as P. A P B P C P A <P B <P C The preset duration can be a fixed 5 seconds, which is the maximum duration to ensure that the smart desks and chairs in the three teaching buildings A, B, and C are fully activated.

[0095] Based on the order of starting power from smallest to largest, the starting order of the three teaching buildings can be A→B→C.

[0096] In other words, the management gateway can first send a group control command to the teaching building gateway of Building A to activate the smart desks and chairs in Building A.

[0097] After sending a group control command to the teaching building gateway of Building A, a group control command is sent to the teaching building gateway of Building B after a 5-second delay, activating the smart desks and chairs in Building B.

[0098] After sending a group control command to the teaching building gateway of Building B, a group control command is sent to the teaching building gateway of Building C after a 5-second delay, activating the smart desks and chairs in Building C.

[0099] This application embodiment sets a delayed start time to ensure that only one building's smart desks and chairs are started at a time, thus achieving staggered start-up and ensuring the reliability of the campus power supply lines.

[0100] In some embodiments of this application, the preset duration can be dynamic and determined based on the startup power of the smart desks and chairs in the teaching building where the current teaching building gateway is located and the startup power of the smart desks and chairs in the teaching building where the next teaching building gateway is located.

[0101] In the embodiments of this application, the absolute value of the difference between the startup power of the smart desks and chairs in the teaching building where the current teaching building gateway is located and the startup power of the smart desks and chairs in the teaching building where the next teaching building gateway is located can be calculated.

[0102] The preset duration is positively correlated with the absolute value of the difference; that is, the larger the absolute value of the difference, the longer the preset duration, and the smaller the absolute value of the difference, the shorter the preset duration.

[0103] For example, the campus includes three teaching buildings, A, B, and C, with starting power denoted as P. A P B P C P A =60000W < P B =63000W < P C =67500W,

[0104] Based on the order of startup power from lowest to highest, the system first sends a group control command to the gateway of teaching building A to activate the smart desks and chairs in teaching building A. After a 3-second delay, it sends a group control command to the gateway of teaching building B to activate the smart desks and chairs in teaching building B. After another 6-second delay, it sends a group control command to the gateway of teaching building C to activate the smart desks and chairs in teaching building C. That is, the total startup time is 9 seconds: first, a group control command is sent to the gateway of teaching building A; then, at the 3-second delay, it is sent to the gateway of teaching building B; and finally, at the 9-second delay, it is sent to the gateway of teaching building C.

[0105] Based on the order of startup power from highest to lowest, the system first sends a group control command to the gateway of teaching building C to activate the smart desks and chairs in teaching building C. After a 6-second delay, it sends a group control command to the gateway of teaching building B to activate the smart desks and chairs in teaching building B. After another 3-second delay, it sends a group control command to the gateway of teaching building A to activate the smart desks and chairs in teaching building A. That is, the total startup time is 9 seconds: first, a group control command is sent to the gateway of teaching building C; at the 6th second, a group control command is sent to the gateway of teaching building B; and at the 9th second, a group control command is sent to the gateway of teaching building A.

[0106] This embodiment of the application links the preset delay duration with the startup power of the two school buildings that are started one after the other, thereby achieving a dynamic preset duration. This ensures that the smart desks and chairs in each school building are fully started and stabilized before starting the smart desks and chairs in the next school building. Compared to a fixed preset duration, dynamically setting the preset duration can reduce the total startup time of the smart desks and chairs in the school buildings, thus improving startup efficiency.

[0107] In some embodiments of this application, the smart campus system includes a management gateway, multiple teaching building gateways, and multiple floor sub-gateways. Each teaching building in the campus is equipped with a teaching building gateway and multiple floor sub-gateways. The teaching building gateway is used to control the smart desks and chairs in the teaching building through the multiple floor sub-gateways in the teaching building.

[0108] Figure 3 This is a flowchart illustrating the implementation of another control method for a smart campus system provided in this application embodiment, such as... Figure 3 As shown, a control method for a smart campus system, applied to each teaching building gateway of the aforementioned smart campus system, includes:

[0109] Encode each floor's sub-gateway in the teaching building;

[0110] Upon receiving a group control command from the management gateway, the command is sequentially sent to each floor's sub-gateway in the teaching building according to their coding order, thereby activating the smart desks and chairs in the building. Each floor's sub-gateway controls the smart desks and chairs on its designated floor.

[0111] Optionally, the teaching building gateway can pre-encode the floor sub-gateways in all teaching buildings on campus. The coding order can be consistent with the floor in the teaching building, or the floor sub-gateways in the teaching building can be randomly coded. The specific choice can be made according to the actual situation.

[0112] This application uses the action performed by a single teaching building gateway when it receives a group control command as an example for illustration. The same applies to other teaching building gateways, and this application will not repeat the details.

[0113] When the teaching building gateway receives the group control command sent by the management gateway, it sends the group control command to each floor sub-gateway in sequence according to the pre-defined coding order of the floor sub-gateways, so that each floor sub-gateway can activate the smart desks and chairs on that floor.

[0114] This application embodiment sets up floor sub-gateways. When the teaching building gateway receives a group control command, it sends the command to each floor sub-gateway in sequence according to the encoding order, thereby enabling the smart desks and chairs in the teaching building to be activated by floor, further reducing the power supply pressure on the campus power supply lines and avoiding damage to the power supply lines.

[0115] Furthermore, when each floor's sub-gateway receives a group control command, it can sequentially activate the smart desks and chairs in each classroom according to the order of classrooms on that floor. Alternatively, when each floor's sub-gateway receives a group control command, it can send the command to each smart desk and chair sequentially according to their coding order, thus activating the specific smart desks and chairs in turn.

[0116] For example, after receiving a group control command, the building gateway of a teaching building can send random group control commands to the floor sub-gateways of each floor according to the order of each floor. After receiving the group control command, each floor sub-gateway will send random start commands to each classroom according to the code of each classroom to start each smart desk and chair. By randomly delaying the start of each shelf, the excessive current load on the circuit caused by simultaneous start is avoided.

[0117] For example, a group control command can be initiated through an app on a computer or handheld terminal (such as a mobile phone). After receiving the group control command, the app uses software strategies to randomly allocate the startup time sequence of each load, so that the devices can start at different times.

[0118] The processed group control commands are sent to each smart desk and chair through gateways at all levels, so that each smart desk and chair can start up in sequence. After starting up, the completion information is sent back to the computer or handheld terminal through gateways at all levels, realizing two-way information interaction and making it easy for managers to know the start-up status of each smart desk and chair in a timely manner.

[0119] For example, a group control command can be initiated via an app on a computer or handheld terminal (such as a mobile phone), and the corresponding group control command is distributed to each smart desk and chair through a gateway. During the installation, construction, and debugging of each smart desk and chair, a random delayed start command is pre-set on the power control terminal. When each load, i.e., the desk / chair, receives the group control command, it will perform the corresponding delayed start.
