Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and particularly to a method and device for generating real-time train commands of a wireless ECP system. Background Art

[0002] Currently, for the control mode of the braking command of the radio-controlled air (ECP) system in heavy-haul railways, a brake pipe pressure sensor is installed on the first vehicle of the train to collect the change of pressure. When the pressure drops beyond a certain set pressure value, the ECP system identifies that the locomotive starts braking and issues a whole-train synchronization command; when the pressure rises beyond a certain set pressure value, the ECP system identifies that the locomotive starts releasing and issues a whole-train release command.

[0003] Due to the long length and large volume of the train brake pipe, the drop and rise of the brake pipe pressure of the first vehicle are gradually transmitted backward. During the process, the brake pipe pressure of the first vehicle fluctuates and requires a stable time. When the ECP system collects the pressure through the pressure sensor to identify the command, to avoid misjudgment, it is necessary to wait for the pressure change to reach a certain amplitude, and the delay of command identification and generation exceeds 1 second, which cannot meet the high-precision synchronous braking and releasing control requirements of heavy-haul trains. Summary of the Invention

[0004] To solve the above problems, the present invention proposes a method and device for generating real-time train commands of a wireless ECP system. By timely obtaining the action signal to ensure timeliness, and then filtering out the fluctuation interference to obtain a reliable pressure value, it can ensure the timeliness of the response of the wireless ECP system to the driver's control.

[0014] Furthermore, the relief signal is collected through the locomotive relief signal line to form an action control instruction, and the pressure signal is obtained through the pressure transmitter of the equalizing air cylinder, including:

[0018] After each vehicle receives the relief action control signal sent by the on-board monitoring device, it starts the relief hold control, that is, cuts off the brake cylinder pressure relief exhaust channel; if a relief confirmation signal is received within the preset time, the relief hold will continue until the clock of each vehicle = the clock carried by the relief action control signal + the preset relief hold time, and then the brake cylinder pressure relief exhaust channel will be opened to achieve synchronous relief of the entire train; otherwise, the relief hold will be released and the brake cylinder pressure relief exhaust channel will be opened.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] In a train of a wireless ECP system, when the driver manipulates the control handle to brake or release the train, first, the handle is pushed to different positions to control the change of the pressure in the equalizing reservoir of the locomotive brake. Then, the change of the pressure in the equalizing reservoir controls the relay valve to charge or discharge the train pipe to follow the change of the pressure in the equalizing reservoir. To adjust and control the pressure change of a certain volume to the target value through charging and discharging, it always takes a certain time delay and there are process pressure fluctuations. The smaller the volume and the simpler the structure, the faster and more accurate it is to control its stability to the target pressure. The equalizing reservoir has a simple structure and a small volume, and when adjusting the pressure, it will stabilize to the target value faster than the brake pipe of the leading car. Moreover, when the driver manipulates the control handle to brake or release the train, there will immediately be a voltage change in the corresponding brake or release signal line of the locomotive brake. Collecting this change to identify the driver's manipulation action has basically no delay.

After receiving the brake action control signal, the communication unit synthesizes it into a brake action control signal with a clock and wirelessly sends it to the on-vehicle monitor, and then continues to send it down to each vehicle to start exhausting the brake pipe; after receiving the pressure signal of the equalizing reservoir after filtering out the fluctuation influence, the communication unit synthesizes it into a pressure signal of the equalizing reservoir with a clock and wirelessly sends it to the on-vehicle monitor, and then sends it down to each vehicle; each vehicle uses the pressure signal of the equalizing reservoir received at the latest time as the target value to perform closed-loop control of exhausting the brake pipe of the vehicle.

[0042] Preferably, when the driver manipulates the control handle to perform a release control on the train, the acquisition and processing unit identifies the voltage change of the locomotive release signal line and outputs a release action control signal to the communication unit; at the same time, the acquisition and processing unit continuously acquires the equalizing reservoir pressure signal, filters out the fluctuation influence, and then sends it to the communication unit. After receiving the release action control signal, the communication unit synthesizes it into a release action control signal with a clock and wirelessly sends it to the on-vehicle monitor, and then continues to send it to each vehicle; after receiving the equalizing reservoir pressure signal with the fluctuation influence filtered out, the communication unit sends the continuous pressure rise condition of the equalizing reservoir to the on-vehicle monitor to form a release confirmation signal; after each vehicle receives the release action control signal sent by the on-vehicle monitor, it starts the release hold control, that is, cuts off the release exhaust passage of the brake cylinder pressure; if it receives the release confirmation signal within the preset time (for example, 5 seconds), it continues the release hold until the clock of each vehicle = the clock carried by the release action control signal + the preset release hold duration, and then opens the release exhaust passage of the brake cylinder pressure to achieve synchronous release of the entire train; otherwise, the release hold is released and the release exhaust passage of the brake cylinder pressure is opened.
