Static wireless signal quality pre-alarm device, system and method

Abstract

The invention discloses a static wireless signal quality pre-warning device, system and method. The system comprises a train, an antenna connected with vehicle-mounted wireless equipment of the train, a wireless access point and the signal quality pre-warning device. The signal quality pre-warning device carries out wireless communication with the antenna of the vehicle-mounted wireless equipment through the wireless access point and has access to a signal quality pre-warning program. When the signal quality pre-warning device detects that the quality of a wireless signal from the vehicle-mounted wireless equipment of the train is normal, the signal quality pre-warning device is shut off, and relative equipment is needless to be detected and maintained. When the device detects that the quality of the signal from the vehicle-mounted wireless equipment of the train is abnormal, the signal quality pre-warning device is started, and relative equipment which is detected to be abnormal is detected and maintained. The static wireless signal quality pre-warning device, system and method solve the technical problems that in the prior art, detection and maintenance of a wireless transmission device of a vehicle are in a periodical maintenance and detection stage, state maintenance cannot be achieved, and particularly, quality of signals cannot be detected and maintained.

Description

technical field [0001] The invention relates to the field of rail traffic signals, in particular to a static wireless signal quality pre-alarm device, system and method for the wireless static data transmission process of a vehicle in a depot in the field of rail traffic. Background technique [0002] In the technical field of wireless static data transmission between trains and grounds in rail transit depots, it is usually required to download the large-capacity data on the vehicle to the ground server in the depot after the train stops at a certain track in the depot. At the same time, when wirelessly transmitting data in the train depot, its position is relatively fixed, and the data transmission task will start when it is parked at a certain position. In the field of rail transit, in the process of wireless static data transmission between trains and ground in the depot, the quality of the wireless signal is one of the important factors affecting the speed of data transm...
