Description

technical field [0001] The invention relates to the field of automatic control of high-speed EMUs and electric locomotives of electrified railways, in particular to a dual-machine hot-standby automatic phase separation device. Background technique [0002] High-speed and heavy-haul is the development direction of China's railways. With the increase of train speed and the continuous extension of electrified railway operation mileage, the requirements for the safety operation standards of rolling stock are getting higher and higher. Therefore, the safe, accurate and reliable passage of electric locomotives through the phase-separation interval has also attracted more and more attention. focus on. For this reason, starting from the construction of the six trunk line speed-raising safety demonstration lines, the Ministry of Railways has listed the electric locomotive on-board automatic phase separation system as the electric locomotive safety technical equipment. Its main func...

Problems solved by technology

[0003] The existing GFX series vehicle-mounted automatic phase separation system lacks the necessary redundancy and status monitoring. At the same time, due to the use of coil-type induction signal receivers, some serious defects have been exposed through the promotion and application in recent years:

[0004] 1. The GFX series automatic over-phase separation system adopts a stand-alone system with PLC as the core, and the reliability of operation cannot be guaranteed. After the interface circuit board or PLC fails, the automatic over-phase separation system will fail. At this time, the locomotive over-phase separation can only It completely relies on the manual operation of the crew. If the system fails during the locomotive operation, it is easy to cause the crew to operate too quickly and cause traffic accidents, which poses a great safety hazard.

For this reason, many locomotive depots use it as an auxiliary support equipment for over-phase separation, and still adopt the control mode of manual over-phase separation, and cannot completely rely on it to realize automatic over-phase control

[0005] 2. The GFX series automatic over-phase separation system uses a mechanical relay to control the output of the 110V locomotive control signal, and the output circuit design is unreasonable, resulting in a greatly reduced electrical life. The failure rate of the output contacts is high, which is easy to cause excessive The phase signal is still not turned off, causing the main circuit breaker of the EMU to fail to close, affecting driving and easily causing driving accidents

[0006] 3. The vehicle sensor of GFX series automatic over-phase separation system adopts coil induction type, which is more sensitive to interference sources such as rail backflow and alloy combined turnout residual magnetism, and has many misoperations

[0007] 4. Since the coil-type magnetic locator must rely on high-speed cutting of the magnetic field line of the ground sensor to generate induction signals, it cannot normally receive the signal of the ground sensor when the locomotive passes through the phase separation area at low speed, and cannot guarantee automatic overshooting when the train running speed is <10km / h phase, the system still needs to rely on the crew to manually over-phase at low speeds.

[0008] 5. There is no operation record, and the working conditions of the system cannot be accurately monitored and analyzed
