ABSTRACT

By studying the current temperature and humidity monitoring system status, a kind of monitoring system of adaptive control strategy state machine model is proposed. The system uses network to connect server and sub control device and sub control device uses RS485 to connect temperature and humidity information collection and control terminal. By logging in management system, users can choose a suitable control strategy to control temperature and humidity basing on different demand and situation. Sub control device uses ARM9 of S3C2410 processor as the master chip, while temperature and humidity information collection and control terminal use AT89S51 as the master chip. To ensure the efficiency and scalability of network communication, to make it easy to build a distributed monitoring system, adaptive control strategy state machine model is used to build data path between server and sub control device. In strategy state machine model control, automatic control strategy can be written to an XML file and sent to the sub control device by the ZeroMQ to guarantee that even the server was broken down or it was no sever situation, the system can still work normally.
