[0018] Embodiment 1

[0019] like Figure 1 As shown, the present application provides an industrial air conditioner remote control method based on a wireless control box, the method comprising:

[0020] A100: Determine multiple access points according to the configuration parameters of the wireless control box, wherein each access point corresponds to at least one air conditioning control terminal;

[0021] Specifically, it should be understood that the wireless control box is an integrated system for managing and controlling wireless terminal devices, which usually includes multiple access points, and the control terminals of the wireless terminal devices are communicatively connected to the wireless control box through the access points.

[0022] In this embodiment, the wireless control box has multiple access points for connecting to wireless terminal devices to send control parameters, and the MAC address of each access point is different. By configuring parameters according to the MAC address of the wireless control box, multiple access points currently in the state of connecting to wireless terminal devices are determined.

[0023] Then, the specific wireless terminal device connection status of multiple access points in the wireless terminal device connection state is interactively determined. It should be understood that in this embodiment, the wireless terminal device connected to the access point is the air conditioning control terminal of the industrial air conditioner, and each access point is connected to at least one air conditioning control terminal.

[0024] A200: collecting the communication transmission distances between the multiple access points and the wireless control box, and simulating and generating a wireless control topology network;

[0025] Specifically, it should be understood that the air conditioning control terminal is arranged in the industrial air conditioning, each access point is correspondingly configured with a wireless communication module, and the industrial air conditioning is connected based on the wireless communication module signal of the air conditioning control terminal and the access point to realize the remote transmission of the air conditioning control parameters of the wireless control box to the industrial air conditioning. The communication transmission distance is the spatial physical distance between the wireless communication module in the access point and the air conditioning control terminal of the industrial air conditioning.

[0026] Based on the spatial position differences of the industrial air conditioners where the air-conditioning control terminals connected to the access points are located, this implementation collects the communication transmission distances between the multiple access points and the wireless control box to obtain multiple groups of communication transmission distances of one or more air-conditioning control terminals connected to the multiple access points. It should be understood that the communication transmission distance is a spatial vector.

[0027] Taking the multiple access points of the wireless control box as multiple starting points, multiple groups of communication transmission distances of one or more air-conditioning control terminals connected to the multiple access points are located to generate the wireless control topology network.

[0028] A300: Performing transmission test optimization according to the wireless control topology network to obtain a preset transmission distance, wherein the preset transmission distance is a safe distance obtained by optimizing the transmission loss between the wireless control box and the access point within a preset threshold;

[0029] In one embodiment, Figure 2 As shown, the method steps provided by the present application also include:

[0030] A311: performing load balancing identification on the wireless control topology network according to the protocol parameters of the multiple access points, and obtaining multiple preset bandwidths corresponding to the multiple access points under the load balancing condition, wherein each access point corresponds to a preset bandwidth;

[0031] A312: Calculate the preset transmission rate of each access point according to the preset bandwidth corresponding to each access point;

[0032] A313: According to the preset transmission rate, the real-time transmission rate of each access point is identified for loss to obtain a transmission rate loss index.

[0033] In one embodiment, a transmission test is performed according to the wireless control topology network to obtain a preset transmission distance. The method step A300 provided in the present application further includes:

[0034] A321: Generate a transmission sample signal to be tested;

[0035] A322: Transmitting the transmission sample signal according to the wireless control topology network to obtain a reception sample signal corresponding to the transmission sample signal;

[0036] A323: Use redundant cyclic verification to verify the transmission sample signal and the reception sample signal to obtain a transmission quality loss index.

[0037] In one embodiment, the method steps provided by the present application further include:

[0038] A331: using the transmission rate loss index and the transmission quality loss index as variables for calculating the transmission loss, and outputting the transmission loss index of each access point;

[0039] A332: Analyze the transmission loss index of each access point to obtain a non-remote access point within the preset threshold, perform maximum distance positioning on the non-remote access point and the wireless control box, and determine a first non-remote access point among the non-remote access points;

[0040] A333: Taking the transmission distance corresponding to the first non-remote access point as the lower limit, construct an optimization interval.

[0041] In one embodiment, the transmission loss index of each access point is analyzed, and the method steps provided by the present application further include:

[0042] A332-1: Obtain a remote access point that is not within the preset threshold, perform minimum distance positioning on the remote access point and the wireless control box, and determine a first remote access point among the non-remote access points;

[0043] A332-2: Taking the transmission distance corresponding to the first non-remote access point as the lower limit and the transmission distance corresponding to the first non-remote access point as the upper limit, construct an optimization interval, and perform optimization in the optimization interval.

[0044] Specifically, in this embodiment, each access point of the wireless control box is pre-deployed with a monitoring device, and multiple monitoring devices of the multiple access points in the connected state obtained above are activated to obtain multiple protocol parameters of the multiple access points, and the data structure of the protocol parameters includes average transmission rate, average signal strength and average data packet loss rate.

[0045] The protocol parameters of each access point are normalized based on linear scaling, and weights are pre-allocated for data indicator components of the protocol parameters. Based on the weight pre-allocation result, weighted calculation is performed on the normalized protocol parameters to obtain a load balancing indicator for each access point.

[0046] The load average index of each access point is added as the denominator, and the load balancing index of each access point is used as the numerator, and multiple preset bandwidth ratios corresponding to the multiple access points under the load balancing condition are calculated to obtain the total bandwidth of the wireless control box interactively, and the total bandwidth is multiplied by the multiple preset bandwidth ratios to obtain the multiple preset bandwidths corresponding to the multiple access points under the load balancing condition, and each access point corresponds to a preset bandwidth.

[0047] Interactively determine multiple transmission efficiency data of multiple access points obtained by performing performance tests on multiple access points based on a historical performance testing tool, and calculate multiple preset transmission rates of the multiple access points according to a transmission rate calculation method of transmission rate = bandwidth / transmission efficiency, according to multiple preset bandwidths and multiple transmission efficiency data corresponding to the multiple access points.

[0048] Then, real-time transmission rate data collection is performed based on multiple monitoring devices pre-deployed at multiple access points to obtain multiple real-time transmission rates of the multiple access points.

[0049] A calculation strategy of dividing the difference between the preset transmission rate and the real-time transmission rate by the preset transmission rate is adopted to calculate and obtain multiple transmission rate loss indicators of multiple access points. The transmission rate loss indicators evaluate the transmission loss of the access points from the transmission rate dimension.

[0050] Furthermore, this embodiment evaluates the transmission loss of the access point from the dimension of transmission information integrity. Specifically, this embodiment generates a transmission sample signal for simulating data transmission in actual communication as test data, and then transmits the transmission sample signal according to the wireless control topology network. Specifically, the transmission signal samples to be tested are sent from multiple air-conditioning control terminals to the corresponding multiple access points, and multiple receiving sample signals corresponding to the transmission sample signal are obtained from the multiple access points.

[0051] A cyclic redundancy check (CRC) is used to compare and verify the transmission sample signal and the received sample signal to detect whether bit errors or losses occur during data transmission. Based on the proportion of bit error or lost data to the overall data of the transmission sample signal, multiple transmission quality loss indicators of multiple access points are calculated.

[0052] Furthermore, the weight distribution of transmission efficiency and transmission quality is preset, and then the transmission rate loss index and the transmission quality loss index of each access point are used as variables for calculating the transmission loss for weighted calculation, and the transmission loss index of each access point with comprehensive transmission quality and transmission rate is output.

[0053] The preset threshold is set. When the transmission loss index of the access point is within the preset threshold, it is considered that the access point can effectively transmit the control signal of the wireless control box to the connected air-conditioning control terminal to control the raw materials of the industrial air-conditioning.

[0054] The preset threshold is used to traverse the multiple transmission loss indicators of the multiple access points to obtain multiple non-remote access points within the preset threshold, and then based on the multiple communication transmission distances of the multiple non-remote access points, the multiple non-remote access points are serialized, the non-remote access points and the wireless control box are positioned at the maximum distance, and the first non-remote access point with the longest communication distance among the multiple non-remote access points is obtained.

[0055] The preset threshold is used to traverse the multiple transmission loss indicators of the multiple access points to obtain multiple remote access points that are not within the preset threshold, and then based on the multiple communication transmission distances of the multiple remote access points, the multiple remote access points are serialized, the remote access points and the wireless control box are positioned at a minimum distance, and the first remote access point among the remote access points that has the closest communication distance to the corresponding access point is determined.

[0056] Taking the transmission distance corresponding to the first non-remote access point as a lower limit and the transmission distance corresponding to the first non-remote access point as an upper limit, an optimization interval is constructed, where the optimization interval is a ring with the transmission distance corresponding to the first non-remote access point as an outer radius length and the transmission distance corresponding to the first non-remote access point as an inner radius length, and the center of the ring is the midpoint of a line connecting the first non-remote access point and the first remote access point.

[0057] The present embodiment performs optimization in the optimization interval. The specific optimization method is to randomly locate and deploy sample air-conditioning control terminals in the optimization interval, and remotely communicate the sample air-conditioning control terminals with the sample access point at the center of the optimization interval. By continuously changing the spatial position of the sample air-conditioning control terminal in the circular ring of the optimization interval and adopting the same method as the above method for obtaining the transmission loss index of the access point, N sample transmission loss indicators that meet the preset number of optimization times are obtained.

[0058] The preset threshold is used to compare the N sample transmission loss indicators to obtain the maximum sample transmission loss indicator that meets the preset threshold, and then the straight-line distance between the position of the sample air-conditioning control terminal corresponding to the sample transmission loss indicator and the center of the optimization space is used as the preset transmission distance. The preset transmission distance is a safe distance obtained by optimizing the transmission loss between the wireless control box and the access point within the preset threshold. When the communication distance between the access point and the air-conditioning control terminal meets the preset transmission distance, it can be considered that the transmission loss between the access point and the air-conditioning control terminal does not affect the actual control effectiveness of the industrial air-conditioning.

[0059] This embodiment achieves the technical effect of obtaining a relatively accurate effective communication distance between the access point and the air conditioner control terminal by performing communication loss analysis.

[0060] A400: Marking the access points corresponding to the preset transmission distance among the multiple access points to obtain an identified access point, wherein the identified access point is a remote access point;

[0061] A500: configuring a signal transfer module, the signal transfer module is used to receive an initial signal from the identification access point, perform signal extension on the initial signal, and output an extended signal of the identification access point;

[0062] A600: The signal relay module then sends the extended signal to the wireless control box for air conditioning monitoring and control.

[0063] Specifically, in this embodiment, the access points corresponding to the preset transmission distance among the multiple access points are marked to obtain identification access points, the identification access points are remote access points, and the identification access points are one or more.

[0064] It should be understood that the data transmission loss between the identification access point and the connected air conditioning control terminal is serious, and the industrial air conditioning cannot be effectively regulated and controlled. Based on this, this embodiment configures a signal transfer module for the identification access point, and the signal transfer module is used to receive the initial signal from the identification access point, and perform signal extension on the initial signal, output the extended signal of the identification access point, and then the signal transfer module sends the extended signal to the wireless control box for air conditioning monitoring and control.

[0065] This embodiment achieves the technical effect that the wireless control box can effectively monitor and control the air-conditioning control terminal that is beyond the effective signal transmission range, thereby improving the effectiveness of remote adjustment and control of industrial air-conditioning.

[0066] In one embodiment, the method steps provided by the present application further include:

[0067] A341: when the multiple access points are updated in real time, the wireless control topology network is optimized according to the updated access points, load balancing identification is performed on the optimized wireless control topology network, and the preset bandwidth is dynamically updated;

[0068] A342: When the updated preset bandwidth is less than the lower limit bandwidth, a first reminder message is generated to remind that there is a risk of extension incompatibility.

[0069] Specifically, in this embodiment, as the multiple access points are updated in real time, the network structure of the wireless control topology network is optimized according to the communication distance and communication direction between the updated access points and the connected air-conditioning control terminals.

[0070] Then, the optimized wireless control topology network is subjected to load balancing identification using the same method as step A311, and the preset bandwidth is dynamically updated.

[0071] The preset bandwidths of the updated multiple access points are compared with the lower bandwidth representing the minimum operating bandwidth requirement of the access point. When the updated preset bandwidth of the access point is less than the lower bandwidth, a first reminder message is generated. The first reminder message is used to remind the current access point that there is a risk of extension incompatibility. The management and control personnel of the wireless control box promptly adjust the air-conditioning control terminal to connect to the access point based on the first reminder message. It is believed that the load condition of the wireless control box is corrected, thereby achieving the technical effect of avoiding the inability of the wireless control box to effectively monitor and control the industrial air conditioner due to load imbalance.

[0072] In one embodiment, a transmission test is performed according to the wireless control topology network to obtain a preset transmission distance. The method step A300 provided in the present application further includes:

[0073] A351: Perform signal reception monitoring on the wireless control topology network to generate a monitoring signal domain;

[0074] A352: Predict the signal density according to the timing nodes of the monitoring signal domain, and when the signal density is greater than the preset signal density, determine a first reduction instruction, and make an advance reduction adjustment to the preset transmission distance based on a preset step size according to the first reduction instruction.

[0075] Specifically, it should be understood that in a communication system, when a large amount of information is sent by a transmitting end, if the processing capacity or bandwidth of the receiving end is limited, information accumulation or loss may occur, which may lead to packet loss, increased transmission delay or data loss, thereby affecting the reliability and efficiency of communication.

[0076] In industrial air-conditioning control by a wireless control box, if multiple air-conditioning control terminals of multiple industrial air-conditioners corresponding to multiple access points at the preset transmission distance transmit a large amount of information to the access point in a close time, the information transmitted by the air-conditioning control terminals at a closer distance can be effectively received, while the access points close to the preset transmission distance experience a greater degree of loss in receiving the transmitted information.

[0077] Based on this, this embodiment monitors the signal reception of the wireless control topology network and generates a monitoring signal domain. Based on the stability of industrial production, the signal transmission of industrial air conditioners usually has a time-periodic change pattern. Based on this, this embodiment analyzes different time points in the monitoring signal domain to predict the signal density at a certain time point in the future and obtain a periodic signal density sequence.

[0078] At the same time, this embodiment determines the preset signal density based on the influence of signal density on signal loss. When the signal density exceeds the preset signal density, it is considered that among the access points that meet the preset transmission distance, the air-conditioning control terminal whose signal transmission distance is close to the preset transmission distance has serious signal transmission loss, which affects the control of the industrial air-conditioning.

[0079] Based on this, this embodiment predicts the signal density according to the timing nodes of the monitoring signal domain. When the signal density is greater than the preset signal density, a first reduction instruction is determined, and the preset transmission distance is adjusted in advance based on the preset step size according to the first reduction instruction, and redundant configuration of the signal relay module and access point matching are performed based on the preset transmission distance after the reduction adjustment.

[0080] This embodiment enables the wireless control box to effectively receive information transmitted by the industrial air conditioner under any signal transmission density, and the wireless control box to effectively control several connected industrial air conditioners.
