Detailed Description
The present application will be described in further detail with reference to the following drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The embodiment of the application provides operation data monitoring equipment of an air conditioner, and the air conditioner is used for adjusting the temperature, the humidity and the like of an environment where the air conditioner is located. The air conditioner can be a single-cooling air conditioner or a cooling and heating dual-purpose air conditioner, and the air conditioner can be in the form of a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner or a ceiling air conditioner, and the like, and the embodiment of the application is not particularly limited to this.
It is understood that the air conditioner includes an indoor unit and an outdoor unit, the indoor unit may include an evaporator and a fan, the outdoor unit may include a compressor and a condenser, and the outdoor unit are connected through a refrigerant pipe. Taking a refrigeration process as an example, a compressor compresses a gaseous refrigerant (such as freon) into a high-temperature high-pressure liquid refrigerant, and then sends the high-temperature high-pressure liquid refrigerant to a condenser for heat dissipation, so as to form a medium-temperature medium-pressure liquid refrigerant; the liquid refrigerant formed by the condenser enters the evaporator of the indoor unit through the refrigerant pipeline, the liquid refrigerant is gasified due to sudden increase of space and reduction of pressure, and a large amount of heat can be absorbed in the process of converting liquid into gas, so that the evaporator can be cooled, and when the fan of the indoor unit blows the indoor air from the evaporator, the fan of the indoor unit blows out cold air.
In the working process, the outdoor unit and the indoor unit need to communicate, for example, the indoor unit sends a control instruction to the outdoor unit to control the operation mode of the outdoor unit (for example, starting a compressor, etc.), and the outdoor unit sends the self operation state, the environmental parameters, the fault codes, etc. to the indoor unit. The indoor unit and the outdoor unit can establish communication through a communication line. In the embodiment of the application, the indoor unit and the outdoor unit can establish a current loop for communication through a communication line.
The current loop is formed by converting strong and weak currents of a strong current communication signal through a diode and a triode in the optical coupler by utilizing the isolation characteristic of the optical coupler, so that a current loop circuit is formed, strong current is isolated, and a closed-loop control effect is realized. The output of the indoor unit corresponds to the input of the outdoor unit, the output of the outdoor unit corresponds to the input of the indoor unit, and the indoor unit and the outdoor unit are connected in pairs to form an annular communication circuit. The core element of the current loop is an optical coupler, and the optical coupler is mainly used for controlling the communication of the strong current part by using the weak current part to achieve the effect of strong current and weak current isolation, so that the work of the weak current part is not interfered by the strong current part, and the effect of protecting the weak current from being influenced by strong current is achieved. The design of the communication between the indoor unit and the outdoor unit based on the current loop may refer to the related art, and is not specifically described herein.
