Vehicle dmi design method for wireless shunting safety protection

Abstract

The invention relates to a vehicle-mounted DMI design method for wireless shunting safety protection, the method comprising: 1) the locomotive runs in the train mode in the section, and the DMI interface displays the speed curve at this time, and the station information reception is valid when entering the station ahead When it is within the radius, the station map will pop up automatically; 2) When the locomotive is approaching the station in front and is in the approaching section outside the incoming signal, the DMI interface will display the status of the incoming signal; 3) When the locomotive is outside the incoming signal, The STP on-board equipment judges the satellite positioning virtual transponder according to the latitude and longitude coordinates and then initiates an application for registration on the ground. If the registration is successful, the locomotive will automatically enter the shunting mode after entering the station. The station map interface displays the real-time location of the locomotive, and the main interface displays the current station name. , front signal status and distance, if the registration fails, the front signal status and distance will not be displayed. Compared with the prior art, the present invention has the advantages of making up for the deficiency that the current STP technology can only display the state of the front signal in the shunting mode.

Description

technical field [0001] The invention relates to a wireless shunting locomotive signal and monitoring system, in particular to a vehicle-mounted DMI design method for wireless shunting safety protection. Background technique [0002] At present, the wireless shunting locomotive signal and monitoring system (hereinafter referred to as the STP system) has been widely used in domestic railway bureaus and stations with frequent local railway shunting operations. As shunting safety protection equipment, the color screen display of the train operation monitoring and recording device (hereinafter referred to as LKJ) provides the driver with the human-computer interaction function of the STP system to assist the driver to drive safely. It works like figure 1 shown. [0003] In the above scheme, the STP vehicle terminal communicates with the ground equipment through the wireless communication module, and forwards the station information sent by the ground equipment to the LKJ. The ...

Problems solved by technology

[0005] 1) Under the train shunting mode, it can display the signal status ahead and the lane occupancy status, while in the train mode, LKJ needs ground track circuit to send the code position status information, otherwise the front signal will not be displayed, which is more suitable for the shunting machine with fixed work area Applicable, but for dispatchers whose work areas are not fixed and need to go back and forth between multiple stations, since they are in train mode during section operation, if there is no track circuit code sending support, the driver cannot pass the LKJ color screen or locomotive before the train enters the station The signal device obtains the signal status ahead and the lane occupancy status;

[0006] 2) The shunting operation plan can only be received when the locomotive is in the shunting monitoring state, and the operation plan can only be displayed on the LKJ color screen in the shunting mode. For most local railways, the shunting operation is flexible and diverse. When the locomotive is in the non-monitoring state, it cannot After receiving the operation plan, when the locomotive enters the station in train mode, the operation plan cannot be displayed, thus affecting the operation efficiency;

[0007] 3) The operating status of the STP vehicle-mounted host is judged only by the color of the indicator light. The method of troubleshooting is relatively simple, and it is difficult to accurately locate the cause of the problem when a problem occurs, which is not convenient for daily maintenance and troubleshooting of the equipment.
