Monitoring system about temperature, humidity and toxic gas

On the basis of computer network theory, we have designed the underground garage´s monitoring system about temperature, humidity and toxic gas. The whole system consists of hardware and software. In this paper, we first introduced the principle of fuzzy control including its characteristics and important methods of applications. The experiment results of the system show us that the whole monitoring system has such advantages as easy structure, stable performance and high reliability. The system could be used in practical applications, such as coal mining industry.
