Abstract

The invention provides a distributed eCall whole vehicle dynamic test wireless signal transmitting and monitoring system which comprises a vehicle movement runway and a vehicle collision or rollover rear area located on the vehicle movement runway. The system further comprises wireless signal transmitting subsystems, and the wireless signal transmitting subsystems are distributed on one side of a vehicle moving runway and in an area after vehicle collision or rollover. The system further comprises wireless signal monitoring subsystems, and the wireless signal monitoring subsystems are distributed on the other side, opposite to the wireless signal transmitting subsystem, of the vehicle moving runway and outside the area after vehicle collision or rollover. According to the distributed eCall vehicle dynamic test wireless signal transmitting and monitoring system provided by the invention, it is ensured that wireless analog signals transmitted by the base station simulator can completely, uniformly and stably cover an eCall vehicle dynamic test area in the whole test process.

Description

technical field [0001] The invention belongs to the field of eCall vehicle dynamic testing, in particular to a distributed eCall vehicle dynamic testing wireless signal transmission and monitoring system. Background technique [0002] As the safety guarantee of the vehicle, the vehicle-mounted eCall system can send the accident-related information, especially the vehicle location information, to the rescue platform immediately after the vehicle accident, thus greatly shortening the rescue time and reducing the casualty rate of the accident to a certain extent. It has gradually become an essential device for vehicles. Whether the vehicle-mounted eCall system can work normally when it is installed on a real vehicle needs to be verified through a functional test during the crash / overturn test. At present, the commonly used method is to use a simulated PSAP (Public Safety Answering Point) test platform to complete the vehicle dynamic test of the vehicle-mounted eCall system whi...
