In recent years, with the impact of global warming, air conditioners have become one of the most commonly used household appliances. This article mainly introduces the research and design scheme of an air-conditioning remote control system based on STC89C52 single-chip microcomputer. The control system includes STC89C52 single-chip microcomputer main control module, Max232 serial port communication module, electromagnetic relay module, temperature acquisition module (DS18B20), LCD liquid crystal display module and virtual terminal module. Using the function of single-chip serial port communication, control commands are issued from the virtual terminal, and the data is transmitted to the single-chip microcomputer through the Max232 serial port communication module, and then the electromagnetic relay is controlled on and off, so as to simulate remote control of the air conditioner switch, air-conditioning cooling and heating operation, To achieve the purpose of remote control of the air conditioner. <br>The system can detect the indoor temperature in real time, and users can control the air conditioner manually and automatically according to their needs. Manual control means that the air conditioner can be turned on manually regardless of the temperature; automatic control means that an upper and lower temperature limit is set arbitrarily. If the indoor temperature exceeds the upper limit, the air conditioner will cool, and if it is below the lower limit, the air conditioner will heat. In the article, several different design schemes for the control system are proposed, and various schemes are analyzed in detail. Based on this, a set of feasible and high-value schemes is formed, and the feasibility of this scheme is carried out. simulation.

In recent years, with the impact of global warming, air conditioning has become one of the most commonly used household appliances. This paper mainly introduces the research and design of an air conditioning remote control system based on STC89C52 single-chip machine. The control system includes STC89C52 single-chip master module, Max232 serial communication module, electromagnetic relay module, temperature acquisition module (DS18B20), LCD display module and virtual terminal module. Using the function of single-chip serial communication, the control instructions are issued from the virtual terminal, and the data is transmitted to the single-chip machine through the Max232 serial communication module, and then the electromagnetic relay is controlled, so as to simulate the remote control of air conditioning switch, air conditioning cooling heating operation, to achieve the purpose of remote control of air conditioning.<br>The system can detect the temperature of the room in real time, and the air conditioner can be manually controlled and automatically controlled as needed. Manual control is no matter how much temperature, you can manually turn on the air conditioning, automatic control is any set a temperature upper and lower limit, if the room temperature exceeds the upper limit of air conditioning on refrigeration, if below the lower limit, air conditioning on heating. In this paper, several different design schemes are proposed for the control system, and the various schemes are analyzed in detail, on the basis of which a feasible and high-value scheme is formed, and the feasibility of the scheme is simulated.
