Description
Technical Field
The invention relates to the technical field of a parking device in a railway, in particular to a parking device control system and a parking device control method.
Background
There are many freight marshalling stations in rail transit for freight train disassembly and reassembly operations to put freight vehicles destined for the same destination in a train. The hump is an important component in a marshalling station and is important equipment for quickly disassembling and regrouping the freight train. The hump is a small hill built on the ground like a camel peak back, is designed into a proper slope according to the transportation requirement, and is paved with turnouts and rails. The regrouping of the freight train is that after the freight train is pushed to the hump top by the shunting machine, the hook lifting operators lift the hooks in turn according to the planned specified number of vehicles, so that different train sets automatically slide down the slope to different tracks in the shunting line of the hump yard by utilizing the potential energy generated by the gravity of the vehicles and the gradient of the hump. In order to ensure the requirements of safety and operation, a speed regulating device and a stopping device are required to be arranged at a certain place, the running speed of a vehicle group is regulated according to the requirement so as to meet the operation requirement, and finally the vehicle group is stopped in a shunting line track of a hump yard.
In order to enable the truck which slips off from the hump to stop on the track, the tail part of the track of the shunting line of the hump yard is provided with an anti-slip device which mainly comprises an iron shoe and a stopping device. The skate is a simple anti-slip device, and shoes are manually placed and removed mainly by manually observing the operation condition of the shunting locomotive; the stopper is a novel anti-sliding device, supports the brake rail by means of lateral supporting force of a spring of the stopper, clamps and stops a vehicle set wheel pair entering a station track between a rail and the brake rail, so that the vehicle set stops, and the vehicle set is prevented from sliding out of the station track to cause an accident. When a train composed of train sets needs to be pulled out from a station track, a control system of the parking device automatically collects relevant operation information of the head and the tail of the grouping field, the parking device corresponding to the station track is controlled to relieve by selecting a machine (namely, the spring in the parking device is compressed, and the lateral pressure is removed), and after the train is pulled out, the control system of the parking device automatically controls the parking device to brake.
The existing parking device control system comprises an upper layer machine and a lower layer machine, when one of the upper layer machine and the lower layer machine breaks down, the parking device control system cannot automatically control an outdoor parking device to relieve and brake, and can only be manually controlled by an emergency disk, so that great influence is caused to the drawing-in and drawing-out operation of a hump shunting track. In addition, once a single point of failure occurs in the existing parking device control system, field maintenance personnel must arrive at the field for maintenance or equipment replacement at the first time, so that a work area where a field operation point is located must be attended by people for 24 hours, and the parking device control system can be recovered to be normal in the shortest time after the single point of failure occurs, and the working pressure of the field maintenance personnel is high.

when the first upper layer machine, the second upper layer machine, the first lower layer machine and the second lower layer machine are all normal, the current output by the positive electrode of the power supply is closed and output through the upper nodes of AXGZJ1 and AGZJ1 or BGZJ1, and is closed and input to the negative electrode of the power supply through the upper nodes of AXGZJ1 and AGZJF1 or BGZJF1, and the parking device control system automatically controls normal work.
When the first upper machine fails and the second upper machine, the first lower machine and the second lower machine are normal, only AGZJ1, AGZJ2, AGZJF1 and AGZJF2 fall. The current output by the positive electrode of the power supply is closed and output through the upper nodes of AXGZJ1 and BGZJ1, and is closed and input to the negative electrode of the power supply through the upper nodes of AXGZJ2 and BGZJF1, and the parking controller control system automatically controls the parking controller to work normally.

When the first lower-level machine fails and the first upper-level machine, the second upper-level machine, and the second lower-level machine are normal, only AXGZJ1 and AXGZJ2 fall. The current output by the positive electrode of the power supply is output by closing the lower node of AXGZJ1, the upper node of BXGZJ1 and the upper node of AGZJ2 or BGZJ2, and is input to the negative electrode of the power supply by closing the lower node of AXGZJ2, closing the upper node of BXGZJ2 and closing the upper node of AGZJF2 or BGZJF2, so that the parking brake control system automatically controls the normal work.
When the second lower layer machine fails and the first upper layer machine, the second upper layer machine and the first lower layer machine are normal, only the BXGZJ1 and the BXGZJ2 fall. The current output by the positive electrode of the power supply is closed and output through the upper nodes of AXGZJ1 and AGZJ1 or BGZJ1, and is closed and input to the negative electrode of the power supply through the upper nodes of AXGZJ2 and AGZJF1 or BGZJF1, and the parking device control system automatically controls the parking device to work normally.

Specifically, when the first upper machine and the second upper machine simultaneously fail and/or the first lower machine and the second lower machine simultaneously fail, the automatic control function of the parking brake control system fails, and only by manual control, and during manual control, the positive power supply is closed and output by the lower nodes of AGZJF1 and BGZJF1, and is closed and input to the negative power supply by the lower nodes of AXGZJ2, AGZJF1, or BGZJF 1.
