Railway guardless crossing remote control system and method

Abstract

The invention discloses a railway guardless crossing remote control system and method. The remote control system comprises a crossing barrier machine, a crossing signal machine, an equipment control unit, a video monitoring unit and a remote operation unit; the equipment control unit is electrically connected with the crossing barrier machine and the crossing signal machine, is in network connection with a remote operation unit, and is used for controlling the working states of the crossing barrier machine and the signal machine according to a remote operation unit instruction; the video monitoring unit is electrically connected with the equipment control unit and / or is in network connection with the remote operation unit, is used for a video monitoring and storing crossing site, and transmits video to the remote operation unit; the operation operation unit is arranged in a far-end control chamber, is in network connection with the equipment control unit of at least two crossings and the video monitoring unit of at least two crossings, is used for a remote video monitoring crossing site, and remotely controls the working states of the crossing barrier machine and the crossing signal machine through the equipment control unit according to a dispatching command. The remote control method comprises the steps of crossing monitoring, remote control and crossing control.

Description

technical field [0001] The invention belongs to the technical field of railway signals, and in particular relates to a remote control system and a remote control method for unguarded railway crossings with simple structure, safety and reliability, high degree of automation and low labor cost. Background technique [0002] Railway level crossing is the level intersection of railway and highway, and is an important facility for railway safety operation. Crossing safety is not only related to the safety of railway traffic, but also the safety of road vehicles and pedestrians. Most large domestic enterprises in the fields of iron and steel, chemical industry, mines, and ports have railway transportation operations. In the enterprises, railway lines are integrated with highways, factory areas, workshops, and living areas, and various railway level crossings are formed along the railway lines. At present, considering the safety of locomotives, vehicles and passing pedestrians, cro...

Problems solved by technology

However, due to the fact that the speed of the trains passing through the crossing is different, and the distance between the sensors on both sides is constant, the crossing is often closed in advance or unblocked after pushing back, so that the closing time of the crossing is too long, resulting in low crossing efficiency; Or the time for alarming and / or closing the crossing is too short, and the safety hazard is prominent

In addition, due to the normal cooperation of multiple sensors and multiple controllers and actuators in the main control box to complete the scheduled alarm and / or closed crossing, the cost of the control system will be too high, the structure is complicated, and the complicated Monitoring and control will also lead to a reduction in the overall reliability. Although there are redundant technologies in the existing technology to improve reliability, it will cause a further increase in cost.

In addition, although the unattended railway crossing adopts the above-mentioned automatic alarm and / or closed crossing technology, if the obstacles in the railway boundary area such as illegal crossing cannot be effectively monitored, there will be great safety hazards
