Measurement And Control

With the rapid development of modern society, the measurement and control requirements of key variables of air conditioning test technology are also increasing. When the parameters of HVAC system are measured and controlled, there are a large number of sensors and instruments used. When sensor failure or measurement error distortion occurs, the air conditioning system cannot operate normally and automatically. At the same time, some variables in the test parameters cannot be directly collected by the sensor. In order to solve these problems, researchers have focused on soft measurement technology in recent years, which provides a good breakthrough for the measurement and control of air conditioning system test parameters. This paper expounds the application of soft measurement technology in HVAC system.

To achieve the centralized monitoring and integrated management of the central air-conditioning system, taking the characteristics of data communications and control complexity in the air-conditioning system into consideration, and combined with the OPC (OLE(Object Linking and Embedding) for Process Control) technology, an intelligent central airconditioning supervisory system is developed and designed. In this paper, after searching the OPC technology standard, the overall structure diagram of the monitoring system is designed, and the OPC server program is also developed by using Knight OPC Server Rapid Development Toolkits. The OPC client application program and man-machine interface are exploited by KingView configuration software. The monitor and control system whose interface is opened is designed for the central air-conditioning. In the end, the experiment result proves that the system operation has good performance for temperature-controller and humidity-controller clustered controlling as well as data communications, thus, satisfying the requirements.
