Abstract：In order to meet the requirement of the detecting node networking in distributed passive detection system，a communication system was designed. The system included the terminal which combines GPRS，CDMA and Ethernet functions in one set，microcontroller LPC2214 was used as the core of the terminal，other units like MC55，EM200 and W5100 were used as the communication module. In addition，the intermediate server was introduced to realize the transceiver communication among different terminals. The test results of the prototype show that the system works steadily and reliably，and is easy to use.
