The invention relates to a wheel axle temperature and wind
pressure monitoring device based on
wireless ad hoc networks and a method for railway passenger cars or wagons, and aims to achieve that random networking can be realized, monitoring work is real-time and accurate, a low
power consumption working mode is realized, the operation is simple, the maintenance cost is low, and the maintenance is simple and convenient. The invention adopts the technical scheme that the wheel axle temperature and wind
pressure monitoring device based on the
wireless ad hoc networks for the railway passenger cars or wagons is characterized in that a locomotive unit and a group of
carriage root units are included, a network
system with a routing function is built between the locomotive unit and each
carriage root unit through a
wireless ad hoc network such as a Zigbee network, a
WiFi network or a
Bluetooth network, wherein, the locomotive unit comprises a coordinator module, a
GSM (
Global System for Mobile Communications) communication module, an industrial computer and a
card reader, and each
carriage root unit comprises a root unit module, a parameter collection sensor and a battery. The inventionis suitable for real-time monitoring of physical parameters such as wheel axle temperature, braking wind pressure and the like of a wagon group with a large quantity.
