For the vehicle’s ocassional appearance of abnormal situation during running, the hybrid real-time detection system with vibration acceleration of the vehicle body as the vehicle running condition signal is designed. This system, with real-time wireless monitoring network composed of sensor nodes in the car body and the virtual programming software LABVIEW, analyzes and displays the acquired signal in real time. In order to verify the detection network, a simulation experiment is done and the experimental results indicate that this real-time wireless monitoring network, with high test accuracy and stability, could effectively detect the running state of vehicle.
