Abstract
The present invention relates to a wireless data transmission system and a data transmission method, belonging to the technical field of railway signals. The existing data manual dumping method of a locomotive signal recorder has the disadvantages that the data of the locomotive signal recorder cannot be totally dumped in preparation of the locomotive or the damage rate of a locomotive signal mainboard is increased. The present invention aims to overcome the foregoing disadvantages. According to the system, a micro-controller collects data of the locomotive signal recorder in real time; a data memory stores the data; and when an antenna of a wireless module enters a wireless local area network that is built by a wireless accessory and covers a locomotive preparation bank region, the micro-controller sends the data stored in the data memory to the server by using the wireless module. The method comprises the steps of building the wireless local area network and setting the server. When a vehicle-mounted device accesses the wireless local area network, the micro-controller sends the data stored in the data memory to the server by using the wireless module, and the server stores the data and forwards the data to a designated terminal. The system and method are used for auto dumping of the data of the locomotive signal recorder.
