Abstract: In order to acquire the vehicle interior environment parameters more conveniently， an experimental system was designed for monitoring the vehicle environment with ZigBee wireless sensor networks. The system consists of the host computer software and multiple ZigBee devices including several wireless acquisition modules， routers and one coordinator. The coordinator collects the date of temperature， humidity， CO concentration and air pressure etc.， which are from the wireless acquisition modules distributed at different positions inside the interior space of vehicle， and it transfers these data to the vehicle management computer in real-time. The host computer program based on the LabVIEW platform can not only display the environmental parameters and corresponding network topology in real-time， but also provide a rich interactive user interface. The experimental results show that the system performed well， and achieved the expected design functionality requirements.
Key words: train vehicle； interior environment parameter； distributed real-time monitoring； ZigBee
