| In this paper, remote monitoring technology of thermal equipment, by such advanced techniques as computer, communications, network and data collecting are studied and the following results are obtained:1. The general structure for remote monitoring systems is designed according to its characteristics and analysis of its requirement. And the technique of its actualization is discussed.2. Monitoring system of constant temperature and constant humidity air conditioning set is developed. According to the requirements of the project, PLC and several datum collection cards are used, the real-time monitoring of air conditioning unit and 36 rooms' temperature or humidity is realized, and the software of remote monitoring based on Ethernet is develped.3. Remote monitoring system of ice thermal storage air conditioning set is developed. Field apparatus consists of several PLC set. The model of remote monitoring system based on PLC network is set up, and the remote monitoring software is developed. This software can be used not only to monitor on the spot, but also to accomplish remote monitoring through modem. |
