In this paper, based on the Siemens S7-200 programmable controller in the central air conditioning control system, hardware and software of the central air-conditioning control system is designed. In hardware design PLC controller is used as controlling core to control temperature and humidity of the entire process. In the software design, control programming and multi-loop control of temperature, humidity PID algorithm are completed by using PLC programming software STEP7 because of its characteristics that it is easy to read and easy to achieve complete control. Lastly, Related parameter is set and the information is displayed by touching screen.

Conditioning Control

In this paper, hardware and software of the central air-conditioning control system is researched by STC series of enhanced 8051 microcontroller. The STC11F 08XE is the main control of the hardware part. Temperature and humidity sensor regulating valve and all kinds of motor are used as external equipment to complete the temperature and humidity of building the internal control of central air conditioner. In terms of software, the program is described by protel99SE software. Microcontroller program is compiled by Microcontroller development tools keil u and STC-ISP. The temperature and humidity control and optimization of central air conditioning are completed by PID parameters. Infrared control unit is operated and liquid crystal is displayed to show the operation results.
