Abstract:

A wireless environment monitoring system based on GPRS is designed for subway tunnels with special requirements for temperature,humidity and CO gas.The data collection terminal is used for getting environmental parameters.By using GPRS as the wireless transmission network,wireless data transmission between host computer and field computers are completed.The MCU of the data collection terminal is LPC2210.The system can meet different GPRS network access scenarios by software modification.The experiment results show that the system can meet the designed requirements.
