The paper introduces a multipoint remote Hygrothermoscope monitoring system based on the MAX485 bus. The system of remote multipoint temperature control is composed of the host machine and slave machine; the host system for display and control, the slave system is responsible for collecting temperature data. Between master machine and slave machine communicate through the RS-485 bus, can realize the distant control room of the scene monitoring. The STC89C54 MCU is used as the controller and DHT11 is used as the temperate and humidity transducer. The hardware and software of the system are outlined. The system has realized multiple measuring points, easy expansion, and high reliability, anti-interference. The whole system has the advantages of simple circuit, reliable, and can be used for measuring temperature, humidity, temperature of building air conditioning control temperature and humidity monitoring and other fields.

Conditioning Control

In this paper, a kind of efficient air-conditioning control system is proposed. PIC18F458 is adopted as main control unit of the system , which collects all kinds of analog singles such as temperature, humidity and so on, then convert them to digital by the A/D itself. After disposing and calculating each analog signal the system drives corresponding actuator to work to adjust temperature, humidity and cleanness of the air in bus, making passengers satisfied with air quality in bus.
