Railway guardless crossing barrier machine remote control device and control method

Abstract

The invention discloses a railway guardless crossing barrier machine remote control device and a control method. The control device comprises a signal switching unit, an equipment control unit, a video monitoring unit and a remote operation unit; the signal switching unit which is in signal connection with the equipment control unit and the video monitoring unit and in network connection with theremote control unit is used for receiving a remote operation unit instruction, converting the instruction into a control signal to the equipment control unit and / or the video monitoring unit and making video monitoring unit video converted to be transmitted to the remote operation unit; the equipment control unit which is connected with a crossing barrier machine and a signal conversion unit is used for controlling the working state of the crossing barrier machine according to the remote operation unit instruction; the video monitoring unit which is in signal connection with the signal conversion unit is used for monitoring and storing monitoring video of a crossing and transmitting the video to the remote operation unit; the remote operation unit which is in network connection with the signal conversion unit is used for remotely monitoring the crossing and remotely controlling the working state of the crossing barrier machine according to a dispatching command. The 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 device and a control method for an unguarded railroad crossing fence machine 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 pedest...

AI Technical Summary

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 illegal crossing cannot be effectively monitored, once the railing machine is closed, it will be reopened artificially or damaged by a vehicle, and the road from the crossing will be broken. Obstacles in the railway boundary area, such as the immersion of the railway line on the side, will also have great safety hazards

In addition, since the whole process requires personnel participation, it not only increases the labor intensity and work pressure of the staff, but also affects the safety of railway operation.
