Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] The structure of a wireless gateway device for monitoring train health status information is as follows: figure 1 As shown, the structure and function of each module are as follows:

[0049] figure 2 The 4G module of the company uses the USR-WIFI232-D2 module, supports IPv4 and IPv6 protocols, and supports two main communication systems of LTE-FDD and LTE-TDD. The module is powered by the power module 3.3V voltage, and it is mainly divided into the following signal groups when connected to the system: USB signal, SIM Card signal, wake-up signal, power reset signal, power signal and ground signal. LINKA indicates the current connection status. UTXD1 and URXD1 are TTL level. These two pins are connected to the serial port of the main controller. UTXD1 is connected to UART2_RXD of the main controller, and URXD1 is connected to UART2_TXD of the main controller. ...

Abstract

The invention discloses a train health condition information monitoring wireless gateway device and a working method thereof. The device comprises a storage, a main controller and a vehicle-ground wireless transmission device, the storage is connected with a train information collection unit, the main controller is connected with the storage and the vehicle-ground wireless transmission device separately, and the wireless transmission device and a data monitoring terminal build communication; the vehicle-ground wireless transmission device comprises a 4G module, a WIFI module and a compass module. Accordingly, the gateway equipment applies the wireless communication technology to maintenance of a high-speed train, data interaction, protocol conversion and the like between the train and thedata monitoring terminal are completed, problems can be found in time, potential safety hazards of the train are eliminated, the information of the train-data monitoring terminal can utilize wirelesscommunication, and the safety of train operation is improved. The device has the advantages of being simple in device access, low in cost, convenient to install, low in maintenance cost and capable ofbeing widely applied to rapid rail traffic.

Description

technical field [0001] The invention relates to the monitoring of train health status information, in particular to a wireless gateway device for monitoring train health status information, which applies multiple wireless communication methods to wireless transmission of high-speed trains, and uses multi-mode communication seamless switching technology to monitor the health status of trains. The information is transmitted to the background data monitoring terminal without barriers. Background technique [0002] At present, China has entered the era of high-speed rail in an all-round way. The types of equipment for high-speed trains have increased accordingly, and the impact of key equipment on the health of high-speed trains has gradually increased. Once the failure of train equipment cannot be detected and resolved in time, it will seriously affect the health of the train. Safe to run. Today's high-speed trains still maintain a planned and periodic maintenance mechanism, w...
