Abstract:A kind of intelligent monitor system module between port and temperature sensor based on Agent was designed, by research on the technology of Agent. Then how to use the control COMM to implementing transmission data and reading data, and how to control sensors effectively are designed. With the object oriented method and the multi-thread technology, a execute module of Agent with well adaptability and a communication module of agent were developed which could transmit real time data quickly. The self-behavior and the self-adaptability were increased to the surroundings of the intelligent monitor system. At last, the technology obstacle of the monitor system running was stably solved.
