Brief Introduction of DJB-Ⅴ Shunting Safety Control and Early Warning Device
The shunting safety control and early warning device uses RFID technology and adopts a ground shunting transponder method to integrate and process information related to shunting operations, which can effectively solve the occurrence of inertial accidents such as “rushing, squeezing, and falling off” during shunting operations.Realize the real-time control of the whole process of shunting weak links such as the main line, key signals, key turnouts, pull-out gears, single-machine trailers, dedicated line shunting, and shunting speed limits, and recorded related information, Analyze the unsafe behaviors of the flight attendants in the operation process through the shunting analysis software, and provide the basis for the safety management
Device composition:
The ground equipment is a passive intelligent transponder. The RFID tag is installed in the sleeper, and the control information is written according to the different safety control functions for storage, and the on-board equipment controls the locomotive according to its control information requirements.
The on-board equipment introduces a locomotive speed information collection system for a set of independent function control hosts. Provide man-machine dialogue interface, which can realize data exchange function. Built-in GPS receiver module, read time and coordinate data, used for time reference and key area as auxiliary positioning and auxiliary judgment of running direction. The double unlock function improves the mutual control ability of the two persons in the flight crew. Modular control design, the safety control type is divided into modular design, such as speed limit control module, access control 1 module, key point control module, dedicated line control module, front distance display module, etc., suitable for various shunting The nature and area of the job. Powerful recording function, for the locomotive through the transponder, the operation of the driver on the controller, and the controller output information to automatically form a shunting file.
Realize function:
1. The shunting operation cuts into the main line safety control;
2. Safety control of locomotives entering and exiting the stock road;
3. Safety control of pull-out line operation;
4. Safety control for multi-access operations;
5. Safety control of key signals;
6. Safety control of unguarded turnouts;
7. Safety control of unguarded crossings;
8. Safety control of dedicated line operation;
9. Security control of single machine entry and exit;
10. The safety control of the single-machine trailer entering the vehicle line operation;
11. Car service shunting promotes connection safety control.
Device characteristics: According to the nature of shunting operations and regional characteristics, the safety control method is modularized. The ground intelligent transponder is divided into point speed limit, linear speed limit, key signal, key switch, entry and exit road, and locomotive entry and exit. And other categories, suitable for any complex shunting operations.
GPS positioning is used for auxiliary positioning control and auxiliary direction discrimination in areas that are inconvenient for maintenance and safety-critical areas to ensure effective control under the condition of ground transponder failure.
The transponder is a passive design and does not require maintenance. It is designed to be used 100,000 times. The ground transponder writes the information of the front control point. Even if a transponder fails, it will not lose control at that point.
Single direction control. During shunting operations on the same line, because the safety critical control points are different between forward and reverse directions, the device realizes unidirectional control.
The speed mode and speed value in the distance ahead display real-time travel distance from the current locomotive point to the front control point and the speed limit value ahead, which is conducive to the control of the speed in foggy shunting operations.
According to the leveling signal control. The requirement of synchronization with the leveling signal is realized. Under the leveling start, advance, and roll-off signals, the early warning device automatically activates the safety control function when the flight attendant is responsible for the lookout in front of the locomotive.
Analysis of shunting documents
Record 1. Every time a locomotive passes an intelligent transponder, the DJB-Ⅴ shunting safety control early warning device automatically generates a record.
Record 2: DJB-Ⅴ shunting safety control early warning device automatically generates a record every time it outputs a piece of control information.
Record 3. A record is automatically generated when the flight attendant performs an operation on the human-machine friendly interface of the DJB-Ⅴ shunting safety control early warning device.
Record 4. The operating speed of the locomotive exceeds the speed limit of the DJB-Ⅴ shunting safety control early warning device to automatically generate a record.
Record 5. Each time the locomotive moves and stops, the DJB-Ⅴ shunting safety control and early warning device automatically generates a record;
Record 6. Each time the locomotive changes direction and runs, the DJB-Ⅴ shunting safety control and early warning device automatically generates a record.
The shunting controller will sort and store the record files of the shifts and output them through the USB interface.
Safe operation control such as pull-out line
1) The point-type speed limit method with different speed limit values is adopted at the position of the pull-out line near the earth stall to control the running speed of the locomotive pull-out line, and the locomotive will start an emergency stop when the point-type speed limit is exceeded.
2) Set a zero-kilometer speed limit method at the earth stop of the lead wire to prevent the locomotive from hitting the earth stop.
