Description

Technical Field

[0001] This invention relates to the field of air conditioning control, and in particular to a control method and system for a split-type air conditioning controller. Background Technology

[0002] In recent years, driven by the "dual carbon" target and related policies, enterprises, industrial parks, and public buildings have increasingly higher demands for energy conservation. Air conditioning accounts for a large proportion of the total energy consumption of buildings, and since air conditioning electricity is mostly public electricity, the operation of air conditioners often lacks effective monitoring. In daily use, there are often situations where the temperature is set too high or too low, or the equipment is left on when people leave, resulting in excessive energy consumption and meaningless energy waste.

[0003] Existing split-type air conditioner control systems primarily use wireless network controllers to set the operating status of various brands of air conditioner controllers. However, since the air conditioner status can only be set and not read, using these universal remote controls in practical applications can overwrite the existing air conditioner control schemes, thereby altering the air conditioner's status and rendering it meaningless, thus failing to achieve energy-saving effects. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a control method and system for a split-type air conditioner controller.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] According to one aspect of the invention, a control method for a split-type air conditioner controller is provided, the method comprising the following steps:

[0007] Step S1: The air conditioner controller actively monitors waveforms, captures information from the infrared control device, and performs waveform analysis.

[0008] Step S2: Perform a fuzzy judgment on the parsed information. If there is a tampered external control instruction, proceed to step S3; otherwise, proceed to step S4.

[0009] Step S3: The air conditioner controller sends a status overwrite instruction to the air conditioner and shortens the timer for the timed overwrite instruction, then returns to step S1.

[0010] Step S4: Determine whether the timed coverage period has been reached. If yes, proceed to step S5; otherwise, return to step S1 until the air conditioner controller is powered off and the process ends.

[0011] Step S5: The air conditioner controller sends a status overwrite command to the air conditioner.

[0012] Preferably, the air conditioner controller sends commands to the air conditioner via infrared.

[0013] Preferably, in step S2, the fuzzy judgment of the parsed information is specifically as follows: First, the air conditioner controller converts the infrared signal received from the infrared control device into an electrical signal. Then, the electrical signal is parsed one by one according to each infrared air conditioner control protocol format. If it conforms to at least one infrared air conditioner control protocol format, it is considered that there is an external control signal.

[0014] More preferably, the infrared air conditioning control protocol includes protocols of ITT, NEC, NRC17, Sharp, NEC and RC-5.

[0015] Preferably, the air conditioner controller receives control instructions from the controller receiving platform, reads control parameters from them, and then sends a status overwrite instruction to the air conditioner.

[0016] More preferably, the controller receiving platform sends control commands to the air conditioner controller via wireless or RS485 serial port.

[0017] According to another aspect of the present invention, a control system for a split-type air conditioner controller is provided, the system including an air conditioner and an infrared control device, the system including an air conditioner controller, wherein the air conditioner controller is communicatively connected to the air conditioner and the infrared control device respectively;

[0018] The infrared control device is used to send air conditioner control commands via infrared and to tamper with the air conditioner status;

[0019] The air conditioner controller is used to intercept control commands from the infrared control device in real time and perform waveform analysis. If it detects that the air conditioner status has been tampered with, it sends a status overwrite command to the air conditioner.

[0020] The air conditioner controller periodically sends status overwrite commands to the air conditioner.

[0021] Preferably, the air conditioner and the infrared control device are connected via infrared communication.

[0022] Preferably, the control system further includes a controller receiving platform, which is communicatively connected to the air conditioning controller.

[0023] Preferably, the controller receiving platform is used to send control commands to the air conditioner controller, wherein the control commands include parameters for setting the air conditioner status;

[0024] The air conditioner controller receives control commands from the controller receiving platform and then sends status overwrite commands to the air conditioner.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] This invention requires no additional hardware and solves the problem of air conditioners being easily altered by infrared control devices other than the air conditioner controller through software algorithms. This ensures the execution of the control scheme of the air conditioner control system, thereby achieving the effect of environmental protection and energy-saving supervision.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0035] This embodiment relates to a control method for a split-type air conditioner controller, which includes signal interception and status overriding. The controller receives control commands from the platform 3 (i.e., the back-end management platform) to the air conditioner controller 1 to configure the air conditioner 2. The air conditioner controller 1 actively monitors and analyzes waveforms to prevent the air conditioner 2 from having its operating status changed by the infrared control device 4 (such as a universal remote control).

[0036] The air conditioner controller 1 can intercept the control commands of the infrared control device 4 in real time and analyze them. If it is determined that the control command is related to air conditioning control, it will immediately issue a command to cover it in order to achieve the blocking effect. At the same time, based on the frequency of the intercepted signal, it will automatically start the timed cover command to ensure that the control state is consistent with the set state of the air conditioner controller 1.

[0037] A control method for a split-type air conditioner controller, such as Figure 1 As shown, the method includes the following steps:

[0038] Step S1: The air conditioner controller 1 actively monitors the waveform, captures information from the infrared control device 4, and performs waveform analysis.

[0039] Step S2: Perform a fuzzy judgment on the parsed information. If there is a tampered external control instruction, proceed to step S3; otherwise, proceed to step S4.

[0040] Step S3: The air conditioner controller 1 sends a status overwrite command to overwrite the status and shortens the timer of the timed overwrite command, then returns to step S1.

[0041] Step S4: Determine whether the timed coverage period has been reached. If yes, proceed to step S5; otherwise, return to step S1 until the air conditioner controller 1 is powered off and the process ends.

[0042] Step S5: Air conditioner controller 1 sends a status overwrite command to air conditioner 2.

[0043] Air conditioner controller 1 can both emit and receive infrared signals. Air conditioner controller 1 stores various infrared air conditioner control protocols, such as ITT, NEC, NRC17, Sharp, NEC, RC-5, etc.

[0044] Specifically, step S2, which involves making a fuzzy judgment on the parsed information, is as follows: the air conditioner controller 1 converts the infrared signal received from the infrared control device 4 into an electrical signal, and parses the electrical signal one by one according to each infrared air conditioner control protocol format. If it conforms to at least one infrared air conditioner control protocol format, it is considered that there is an external control signal.

[0045] The air conditioner controller 1 analyzes the waveform of the received infrared signal as follows: Figures 3-6 .

[0046] This embodiment also relates to a control system for a split-type air conditioner controller, such as... Figure 2 As shown, the system includes an air conditioner controller 1, an air conditioner 2 and an infrared control device 4 that are respectively connected to the air conditioner controller 1, and a controller receiving platform 3 that is connected to the air conditioner controller 1.

[0047] Among them, the controller receiving platform 3 is used to send the parameters that the air conditioner controller 1 needs to set the air conditioner status;

[0048] Infrared control device 4 is used to send air conditioning control commands via infrared to tamper with the air conditioning status.

[0049] Air conditioner controller 1 receives instructions from controller receiving platform 3 to set air conditioner 2. At the same time, air conditioner controller 1 intercepts control instructions from infrared control device 4 in real time and performs waveform analysis. If it finds that the air conditioner status has been tampered with, it sends a status overwrite instruction to air conditioner 2. Air conditioner controller 1 also periodically sends a status overwrite instruction to air conditioner 2 to reset the air conditioner status.

[0050] The air conditioner controller 1 carries the control method of the present invention.

[0051] Air conditioner 2 is connected to air conditioner controller 1 and infrared control device 4 via infrared communication.

[0052] The air conditioner controller 1 is connected to the controller receiving platform 3 via wireless or RS485 serial port, where wireless includes WLAN, 4G and 5G networks.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
