[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of a rental air conditioning control device in the hardware operating environment involved in the embodiment of the present invention.

[0045] like Figure 1As shown, the rental air conditioning control device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), and optionally the user interface 1003 may also include a standard wired interface and a wireless interface. The wired interface of the user interface 1003 may be a USB interface in the present invention. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable memory (NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0046] Those skilled in the art will understand that Figure 1 The structure shown in does not constitute a limitation on the rental air conditioning control equipment, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0047] like Figure 1 As shown, the memory 1005 identified as a computer storage medium may include an operating system, a network communication module, a user interface module, and a rental air conditioning control program.

[0048] exist Figure 1 In the rental air conditioning control device shown, the network interface 1004 is mainly used to connect to the background server and communicate data with the background server; the user interface 1003 is mainly used to connect to the user device; the rental air conditioning control device calls the rental air conditioning control program stored in the memory 1005 through the processor 1001, and executes the rental air conditioning control method provided by the embodiment of the present invention.

[0049] Based on the above hardware structure, an embodiment of the rental air conditioning control method of the present invention is proposed.

[0050] Reference Figure 2 , Figure 2 This is a flow chart of the first embodiment of the rental air conditioner control method of the present invention, which provides the first embodiment of the rental air conditioner control method of the present invention.

[0051] Step S10: When receiving the rental air conditioner control instruction, searching for the instruction forwarding device corresponding to the rental air conditioner to be controlled, wherein the instruction forwarding device has previously established a communication sub-network with the rental air conditioner to be controlled.

[0052] It should be understood that the execution subject of the method of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a server, or other electronic devices capable of performing the same or similar functions, and this embodiment is not limited thereto. In this embodiment and other embodiments, the rental of air conditioning control equipment is used as an example for illustration.

[0053] It should be noted that the user can initiate a rental air conditioner control command through the client corresponding to the rental air conditioner control device. The rental air conditioner control command can be at least one of a rental air conditioner status query command, a rental air conditioner unlock command, and a rental air conditioner remote diagnosis command, which is not limited in this embodiment.

[0054] It is understood that receiving a rental air conditioner control command indicates that the user wishes to control the rental air conditioner. Therefore, it is necessary to first identify the rental air conditioner to be controlled. This identification may include extracting an air conditioner identifier from the rental air conditioner control command and identifying the rental air conditioner to be controlled based on the identifier. The air conditioner identifier represents the identity of the air conditioner.

[0055] It should be understood that the step of determining the command forwarding device may specifically include searching a preset device table for the command forwarding device corresponding to the rental air conditioner to be controlled. The preset device table includes a correspondence between rental air conditioners and command forwarding devices. This correspondence between rental air conditioners and command forwarding devices may be pre-entered by the administrator of the rental air conditioner control device, or may be automatically entered by the rental air conditioner control device when the command forwarding device establishes a communication sub-network with the rental air conditioner. This embodiment is not limited thereto.

[0056] It should be noted that the communication subnetwork may be a short-range wireless communication network. The short-range wireless communication network may be at least one of a Bluetooth communication subnetwork, a Zigbee communication subnetwork, and a WiFi communication subnetwork. In this embodiment and other embodiments, the Bluetooth communication subnetwork is used as the communication subnetwork for illustration.

[0057] It can be understood that after the command forwarding device establishes a communication sub-network with the rental air conditioner to be controlled in advance, the rental air conditioner control command no longer needs to be sent to all rental air conditioners through the Narrow Band Internet of Things (NB-IoT). It only needs to be sent to the command forwarding device through the NB-IoT network, and then the command forwarding device sends it to the rental air conditioner through the Bluetooth communication sub-network, thereby avoiding the defect of some devices losing connection due to the narrow communication bandwidth of the NB-IoT cellular network, and improving the reliability of rental air conditioner control.

[0058] It should be noted that the instruction forwarding device may be a device capable of establishing a short-range wireless communication network.

[0059] Step S20: sending the rental air conditioner control instruction to the instruction forwarding device, so that the instruction forwarding device forwards the rental air conditioner control instruction to the rental air conditioner to be controlled through the communication subnetwork.

[0060] It should be noted that the rental air conditioning control device and the command forwarding device can communicate through the NB-IoT network to ensure the reliability of communication.

[0061] It should be understood that after receiving the rental air conditioner control instruction, the instruction forwarding device can forward the rental air conditioner control instruction to the rental air conditioner to be controlled through the communication subnetwork.

[0062] For easier understanding, refer to Figure 3 This is for illustration only, but does not limit this solution. Figure 3 This is a schematic diagram of rental air conditioning control, which includes instruction forwarding devices S1, S2, and rental air conditioners 1, 2, 3, 4, 5, 6, 7, and 8.

[0063] A first Bluetooth communication sub-network is established between the instruction forwarding device S1 and the rental air conditioners 1, 2, 3, and 4, and a second Bluetooth communication sub-network is established between the instruction forwarding device S2 and the rental air conditioners 5, 6, 7, and 8.

[0064] According to the rental air conditioner control instruction, it is determined that the rental air conditioner to be controlled is 3, and the instruction forwarding device corresponding to the rental air conditioner 3 to be controlled is S1. The rental air conditioner control device first sends the rental air conditioner control instruction to the instruction forwarding device S1 through the NB-IoT network, and then the instruction forwarding device S1 forwards the rental air conditioner control instruction to the rental air conditioner 3 to be controlled through the first Bluetooth communication subnetwork.

[0065] In a specific implementation, for example, the rental air conditioner control device sends a status query command to the command forwarding device, which then queries the status of each rental air conditioner one by one. Because internal queries are performed via Bluetooth communication between each rental air conditioner, a reliable transmission channel is established as long as the rental air conditioner is powered on, preventing loss of connection. The command forwarding device obtains the status of each rental air conditioner and then reports it to the rental air conditioner control device.

[0066] Compared with the existing technology in which all rental air conditioners in the area are connected to the base station through the NB-IoT cellular network, this embodiment first sends the rental air conditioner control instructions to the instruction forwarding device through the NB-IoT cellular network, and then the instruction forwarding device forwards the rental air conditioner control instructions to the rental air conditioner to be controlled through the Bluetooth subnet. Therefore, there is no need for all rental air conditioners to connect to the base station through the NB-IoT cellular network, thereby avoiding the defect of some devices losing connection due to the narrow communication bandwidth of the NB-IoT cellular network, and improving the reliability of rental air conditioner control.

[0067] Reference Figure 4 , Figure 4 This is a flow chart of the second embodiment of the rental air conditioning control method of the present invention, based on the above Figure 2 The first embodiment shown here provides a second embodiment of the rental air conditioner control method of the present invention.

[0068] In the second embodiment, before step S10, the method further includes:

[0069] Step S01: obtaining rental air conditioner information of a target area, and selecting a target air conditioner from the rental air conditioners in the target area based on the rental air conditioner information.

[0070] It should be noted that the target area may be an area where rental air conditioners are installed, for example, a school, community, or residential area where rental air conditioners are installed.

[0071] The rental air conditioner information may include air conditioner model information, air conditioner signal information, and air conditioner quantity information.

[0072] It should be understood that some models of rental air conditioners have strong communication capabilities and are suitable for use as command forwarding devices. Therefore, step S01 may specifically include extracting the air conditioner model information from the rental air conditioner information and matching the air conditioner model information with preset model information. If a match is successful, the matching rental air conditioner is selected as the target air conditioner. The preset model information can be pre-set by the administrator of the rental air conditioner control equipment.

[0073] Step S02: Grouping the rental air conditioners based on the target air conditioners to obtain a rental air conditioner group.

[0074] It should be understood that the purpose of grouping the rental air conditioners is to build a communication sub-network based on the rental air conditioner groups. Therefore, when grouping the rental air conditioners, the rental air conditioners with similar locations should be grouped together to ensure the success of the communication sub-network building.

[0075] It is understandable that step S02 may specifically include grouping the rental air conditioners whose distance from the target air conditioner is less than a preset threshold, wherein the preset threshold may be pre-set.

[0076] Step S03: establishing a communication sub-network with the target air conditioner as the instruction forwarding device of the rental air conditioner group.

[0077] It should be understood that in this embodiment, a communication subnetwork is established with the target air conditioner as the instruction forwarding device of the rental air conditioner group, so that there is no need to add additional network construction equipment and a communication subnetwork can be directly established between the rental air conditioners.

[0078] It should be noted that the instruction forwarding device of the rental air conditioner group is used to establish a communication sub-connection with each rental air conditioner in the rental air conditioner group. The communication sub-connection may be a Bluetooth connection.

[0079] The second embodiment directly selects instruction forwarding devices from the rented air conditioners, thereby eliminating the need for additional network construction equipment, reducing costs, and lowering the difficulty of network construction.

[0080] Reference Figure 5 , Figure 5 This is a flow chart of the third embodiment of the rental air conditioning control method of the present invention, based on the above Figure 4 The second embodiment shown provides a third embodiment of the rental air conditioner control method of the present invention.

[0081] In the third embodiment, step S01 includes:

[0082] Step S011: Acquire rental air conditioner information in a target area, and extract air conditioner signal information and air conditioner quantity information from the rental air conditioner information.

[0083] It should be noted that the air conditioner signal information can be used to indicate the ability of the air conditioner to receive and transmit signals. The air conditioner signal information can include reference signal reception quality, signal to interference plus noise ratio, and transmission power.

[0084] It should be understood that step S011 may specifically be: extracting the air conditioner signal information and the air conditioner quantity information from the rental air conditioner information based on the information identifier, wherein the information identifier is used to indicate the information content.

[0085] Step S012: sorting the rental air conditioners in the target area according to the air conditioner signal information to obtain a sorting result.

[0086] It should be understood that air conditioners may experience communication failures during operation. Therefore, relying solely on the air conditioner model to determine the target air conditioner may result in the target air conditioner being unable to communicate. Therefore, when selecting a target air conditioner, it is necessary to consider the signal information of the rental air conditioners to select the target air conditioner with the strongest signal.

[0087] It is understandable that step S012 may specifically include: determining the signal strength of the rental air conditioners in the target area according to the air conditioner signal information, and sorting the rental air conditioners from large to small according to the signal strength to obtain a sorting result.

[0088] Step S013: selecting a target air conditioner from the leased air conditioners according to the air conditioner quantity information and the sorting result.

[0089] It should be understood that if a large number of rental air conditioners are selected as target air conditioners, this may result in a large number of air conditioners connecting to the NB-IoT cellular network, affecting the data transmission rate. Therefore, the number of air conditioners should also be considered when selecting target air conditioners.

[0090] It is understandable that step S013 may specifically be: determining the number of instruction forwarding devices according to the number of air conditioners, and selecting a rental air conditioner with a higher number of instruction forwarding devices from the sorting result as the target air conditioner.

[0091] It should be understood that determining the number of command forwarding devices based on the air conditioner quantity information may be performed by searching a preset quantity table for the number of command forwarding devices corresponding to the air conditioner quantity information. The preset quantity table includes a correspondence between the air conditioner quantity information and the number of command forwarding devices, and the correspondence between the air conditioner quantity information and the number of command forwarding devices may be pre-set.

[0092] Furthermore, in order to make the number of instruction forwarding devices more in line with actual usage requirements, step S013 includes:

[0093] Obtaining an air conditioning capacity coefficient of the target area, and determining the number of instruction forwarding devices according to the air conditioner quantity information and the air conditioning capacity coefficient;

[0094] A target air conditioner is selected from the leased air conditioners according to the number of the instruction forwarding devices and the sorting result.

[0095] It should be noted that the air conditioning capacity coefficient is used to indicate the number of rental air conditioners that the communication subnetwork can accommodate.

[0096] It should be understood that each communication sub-network can accommodate a limited number of rental air conditioners. Therefore, when selecting a target air conditioner, the air conditioner capacity coefficient of the target area also needs to be considered.

[0097] In the specific implementation, for example, A represents the number of air conditioners in the target area, and B represents the air conditioner capacity coefficient in the target area, then the number of instruction forwarding devices

[0098] It is understandable that the target air conditioner may be selected by selecting a rental air conditioner with a higher ranking in terms of the number of rental air conditioners from the sorting results as the target air conditioner.

[0099] The third embodiment considers both the signal strength of the rental air conditioners and the number of rental air conditioners in the target area when selecting the target air conditioners, thereby ensuring that the selected target air conditioners have strong signals and an appropriate number.

[0100] In a specific implementation, for example, rental air conditioner control devices are distributed and managed by cell. First, the signal status curve of the rental air conditioners in a cell is calculated, using the following parameters: rsrq (reference signal reception quality); sinr (signal to interference and noise ratio); and txpwer (transmit power). The air conditioners in the cell are then counted and ranked, yielding a ranked list S. Assuming the number of air conditioners in a cell is A = 3n and the optimal capacity factor B = n, the edge network distribution count is calculated as C = A / B = 3. Based on the network distribution count C, the top air conditioners in the total list S are selected as the root nodes of the distribution subnetwork. These are S1, S2, and S3, respectively. The rental air conditioner control device designates the root node role as a command forwarding device. Each root node establishes a subnetwork via Bluetooth according to the following algorithm: Subnetwork nodes are (Sn, Sn+C*1, Sn+C*2, ... Sn+C*n). For example, subnetwork S1 = (S1, S1+3*1, S1+3*2, ... S1+3*n).

[0101] In the third embodiment, step S02 includes:

[0102] Step S021: Acquire the signal strength information of the target air conditioner and the distance information between the target air conditioner and the rental air conditioner.

[0103] It should be noted that the signal strength information may be the strength information of the signal transmitted by the target air conditioner when a communication sub-network is established with the target air conditioner as the instruction forwarding device.

[0104] It should be understood that if the target air conditioner's signal strength cannot reach the rental air conditioner, forcibly establishing a communication sub-network connection between the target air conditioner and the rental air conditioner may result in signal instability. Therefore, when determining the rental air conditioner group, it is necessary to consider the target air conditioner's signal strength information and the distance information between the target air conditioner and the rental air conditioner to ensure that the target air conditioner and the rental air conditioner whose signal strength can reach the rental air conditioner are grouped into the same rental air conditioner group.

[0105] Step S022: grouping the rental air conditioners according to the signal strength information and the distance information to obtain a rental air conditioner group.

[0106] It should be understood that step S022 may specifically include matching the signal strength information with the distance information, and if the match is successful, assigning the successfully matched rental air conditioner to the rental air conditioner group where the target air conditioner is located. Matching the signal strength information with the distance information may include matching the signal strength coverage range with the distance, and if the match is successful, it indicates that the signal coverage range of the target air conditioner includes the rental air conditioner.

[0107] The third embodiment introduces the signal strength information of the target air conditioner and the distance information between the target air conditioner and the rented air conditioner to group the rented air conditioners, thereby ensuring that each rented air conditioner in the rented air conditioner group is successfully networked with the target air conditioner, thereby improving the network construction reliability of the communication subnet.

[0108] Reference Figure 6 , Figure 6 This is a flow chart of the fourth embodiment of the rental air conditioning control method of the present invention, based on the above Figure 2 The first embodiment shown is a fourth embodiment of the rental air conditioner control method of the present invention.

[0109] In the fourth embodiment, step S10 includes:

[0110] Step S101: upon receiving a rental air conditioner control instruction, the rental air conditioner control instruction is sent to the rental air conditioner to be controlled via a preset communication network.

[0111] It should be noted that the preset communication network may be a narrowband Internet of Things (NB-IoT).

[0112] Step S102: When the sending fails, search for the instruction forwarding device corresponding to the rental air conditioner to be controlled.

[0113] It should be understood that the rental air conditioner control command can be sent to the rental air conditioner to be controlled via the NB-IoT network first. If the transmission fails, it indicates that the NB-IoT network is congested. In this case, the rental air conditioner control command can be sent to the command forwarding device via the NB-IoT network first, and then the command forwarding device will forward it to the rental air conditioner to be controlled via the Bluetooth subnet.

[0114] The fourth embodiment first attempts to send instructions through the NB-IoT network. When the sending fails, the instruction is forwarded through the instruction forwarding device, so that instructions can be sent through multiple channels to ensure the reliability of the rental air conditioner control.

[0115] In the fourth embodiment, step S20 includes:

[0116] Step S201: Sending a status query instruction to the instruction forwarding device, so that the instruction forwarding device queries the status of the rental air conditioner to be controlled through the communication subnetwork.

[0117] It is understandable that the status query instruction can be sent to the instruction forwarding device through the NB-IoT network.

[0118] It should be understood that after receiving the status query instruction, the instruction forwarding device can forward the status query instruction to the rental air conditioner to be controlled. After receiving the status query instruction, the rental air conditioner to be controlled starts self-inspection and feeds back status information to the instruction forwarding device after the inspection is completed.

[0119] Step S202: receiving the status of the rental air conditioner to be controlled fed back by the instruction forwarding device.

[0120] It is understandable that after receiving the status information fed back by the rental air conditioner to be controlled, the instruction forwarding device can determine the status of the rental air conditioner to be controlled and send the status of the rental air conditioner to be controlled to the rental air conditioner control device.

[0121] Step S203: When the state is online, the rental air conditioner control instruction is sent to an instruction forwarding device, so that the instruction forwarding device forwards the rental air conditioner control instruction to the rental air conditioner to be controlled through the communication subnetwork.

[0122] It should be understood that when the status is online, it means that the rental air conditioner to be controlled is in normal state. At this time, the rental air conditioner control command can be sent to the command forwarding device via the NB-IoT network.

[0123] In the specific implementation, for example, when a dormitory in the community reports that the air conditioning is abnormal, or the air conditioning cannot be used after payment authorization, the rental air conditioning control device will first try to diagnose and unlock the rental air conditioning to be controlled corresponding to the after-sales complaint form through the NB-IoT network. If the connection fails, the command forwarding device corresponding to the rental air conditioning to be controlled is found. The rental air conditioning control device issues an instruction to the command forwarding device to query the status of the rental air conditioning to be controlled. After the command forwarding device queries the online status of the rental air conditioning to be controlled through the Bluetooth channel, the command forwarding device issues an edge management instruction through the Bluetooth channel to diagnose and unlock the rental air conditioning to be controlled.

[0124] In the fourth embodiment, before sending the rental air conditioner control instruction to the instruction forwarding device, the status of the rental air conditioner to be controlled is first checked, and the instruction is sent only when the rental air conditioner to be controlled is online, thereby ensuring that the rental air conditioner to be controlled can receive the rental air conditioner control instruction.

[0125] In addition, an embodiment of the present invention further provides a storage medium on which a rental air conditioner control program is stored. When the rental air conditioner control program is executed by a processor, the rental air conditioner control method described above is implemented.

[0126] In addition, refer to Figure 7 The embodiment of the present invention further provides a rental air conditioning control device, the rental air conditioning control device comprising:

[0127] The device search module 10 is used to search for a command forwarding device corresponding to the rental air conditioner to be controlled when receiving a rental air conditioner control command. The command forwarding device has established a communication sub-network with the rental air conditioner to be controlled in advance.

[0128] It should be noted that the user can initiate a rental air conditioner control command through the client corresponding to the rental air conditioner control device. The rental air conditioner control command can be at least one of a rental air conditioner status query command, a rental air conditioner unlock command, and a rental air conditioner remote diagnosis command, which is not limited in this embodiment.

[0129] It is understood that receiving a rental air conditioner control command indicates that the user wishes to control the rental air conditioner. Therefore, it is necessary to first identify the rental air conditioner to be controlled. This identification may include extracting an air conditioner identifier from the rental air conditioner control command and identifying the rental air conditioner to be controlled based on the identifier. The air conditioner identifier represents the identity of the air conditioner.

[0130] It should be understood that the step of determining the command forwarding device may specifically include searching a preset device table for the command forwarding device corresponding to the rental air conditioner to be controlled. The preset device table includes a correspondence between rental air conditioners and command forwarding devices. This correspondence between rental air conditioners and command forwarding devices may be pre-entered by the administrator of the rental air conditioner control device, or may be automatically entered by the rental air conditioner control device when the command forwarding device establishes a communication sub-network with the rental air conditioner. This embodiment is not limited thereto.

[0131] It should be noted that the communication subnetwork may be a short-range wireless communication network. The short-range wireless communication network may be at least one of a Bluetooth communication subnetwork, a Zigbee communication subnetwork, and a WiFi communication subnetwork. In this embodiment and other embodiments, the Bluetooth communication subnetwork is used as the communication subnetwork for illustration.

[0132] It can be understood that after the command forwarding device establishes a communication sub-network with the rental air conditioner to be controlled in advance, the rental air conditioner control command no longer needs to be sent to all rental air conditioners through the Narrow Band Internet of Things (NB-IoT). It only needs to be sent to the command forwarding device through the NB-IoT network, and then the command forwarding device sends it to the rental air conditioner through the Bluetooth communication sub-network, thereby avoiding the defect of some devices losing connection due to the narrow communication bandwidth of the NB-IoT cellular network, and improving the reliability of rental air conditioner control.

[0133] It should be noted that the instruction forwarding device may be a device capable of establishing a short-range wireless communication network.

[0134] The instruction sending module 20 is used to send the rental air conditioner control instruction to the instruction forwarding device, so that the instruction forwarding device forwards the rental air conditioner control instruction to the rental air conditioner to be controlled through the communication subnetwork.

[0135] It should be noted that the rental air conditioning control device and the command forwarding device can communicate through the NB-IoT network to ensure the reliability of communication.

[0136] It should be understood that after receiving the rental air conditioner control instruction, the instruction forwarding device can forward the rental air conditioner control instruction to the rental air conditioner to be controlled through the communication subnetwork.

[0137] For easier understanding, refer to Figure 3 This is for illustration only, but does not limit this solution. Figure 3 This is a schematic diagram of rental air conditioning control, which includes instruction forwarding devices S1, S2, and rental air conditioners 1, 2, 3, 4, 5, 6, 7, and 8.

[0138] A first Bluetooth communication sub-network is established between the instruction forwarding device S1 and the rental air conditioners 1, 2, 3, and 4, and a second Bluetooth communication sub-network is established between the instruction forwarding device S2 and the rental air conditioners 5, 6, 7, and 8.

[0139] According to the rental air conditioner control instruction, it is determined that the rental air conditioner to be controlled is 3, and the instruction forwarding device corresponding to the rental air conditioner 3 to be controlled is S1. The rental air conditioner control device first sends the rental air conditioner control instruction to the instruction forwarding device S1 through the NB-IoT network, and then the instruction forwarding device S1 forwards the rental air conditioner control instruction to the rental air conditioner 3 to be controlled through the first Bluetooth communication subnetwork.

[0140] In a specific implementation, for example, the rental air conditioner control device sends a status query command to the command forwarding device, which then queries the status of each rental air conditioner one by one. Because internal queries are performed via Bluetooth communication between each rental air conditioner, a reliable transmission channel is established as long as the rental air conditioner is powered on, preventing loss of connection. The command forwarding device obtains the status of each rental air conditioner and then reports it to the rental air conditioner control device.

[0141] Compared with the existing technology in which all rental air conditioners in the area are connected to the base station through the NB-IoT cellular network, this embodiment first sends the rental air conditioner control instructions to the instruction forwarding device through the NB-IoT cellular network, and then the instruction forwarding device forwards the rental air conditioner control instructions to the rental air conditioner to be controlled through the Bluetooth subnet. Therefore, there is no need for all rental air conditioners to connect to the base station through the NB-IoT cellular network, thereby avoiding the defect of some devices losing connection due to the narrow communication bandwidth of the NB-IoT cellular network, and improving the reliability of rental air conditioner control.
