Multi-vehicle-type universal rail platform door safety positioning system and control method

Abstract

The invention discloses a multi-vehicle-type universal rail platform door safety positioning system and a control method.The multi-vehicle-type universal rail platform door safety positioning system comprises ground control equipment arranged on a station platform, a plurality of vehicle-mounted modules arranged on a train and used for receiving information of the ground control equipment and controlling operation of the train, and a plurality of vehicle-mounted modules arranged on the train and used for receiving information of the ground control equipment and controlling operation of the train; a barrier unit controlled by the ground control device; the control method specifically comprises the steps that a vehicle-mounted module of any train sends first information to ground control equipment based on a preset distance, and the ground control equipment detects the stop position of the train and sends a first signal to a barrier unit controller based on the received first information, so that the barrier unit is controlled to be shifted and coupled, and second information is sent to the vehicle-mounted module; and the train-mounted module controls the train to stop and the train door to open based on the received second information and the read third information. According to the invention, different types of trains can be universally operated in the same station, so that the trains are safer to operate, and abnormal conditions can be conveniently and timely handled.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a multi-vehicle universal rail platform door safety positioning system and a control method. Background technique [0002] In recent years, with the rapid development of the country's economic level, more and more cities have completed or started the construction or expansion of subways and high-speed rails, intercity trains, subway vehicles, trams, trolleys, monorail vehicles, light rail vehicles, wheels Type vehicles, water-propelled vehicles, diesel-powered vehicles and electric vehicles have become the first choice for passengers to travel, and the number of passengers traveling by public transport is increasing day by day. Following this, the following main problems arise. [0003] Question 1: The safety of passengers falling off the track [0004] The depth of the train track below the platform poses a serious safety risk as passengers wait on the platform for an app...

AI Technical Summary

Problems solved by technology

[0003] Question 1: The safety of passengers falling off the track

[0006] One existing approach is to provide a static wall assembly, however this static wall arrangement is insufficient for intercity diesel powered trains that stop at different or unpredictable locations within a station

In addition, the bottom of the train is above the platform, presenting an obvious safety risk that unsuspecting passengers, especially small children, could fall onto the train tracks through the opening between the bottom of the train and the platform

[0007] Problem 2: Matching of trains and platform doors

[0011] Platform door and train door systems configured in this way are more complex and therefore more expensive

Moreover, when unexpected situations occur, such as brake errors, track or train hardware abnormalities, passengers falling off the tracks, etc., which cause the train’s parking position to change, the train’s parking position on the track will shift forward and backward. The platform door is required to locate, open or close the position of the train, and it is difficult to realize such an operation in a station configured according to the traditional method

In addition, even if the parking position of the train has not changed, some emergencies may require restricting the entry and exit of specific cars, such as closing the door of a certain car or the platform door. The configuration according to the traditional method is not efficient and effective. do this reliably

[0012] Question 3: Support mixed running of trains of various specifications

However, during the construction and official operation of the project, this configuration method will limit the subsequent development of rail transit. For example, when the train in use is scrapped, if the current station status is to be maintained, a train of the same specification must be purchased again. And if you want to replace the train with new specifications, you must re-plan and adapt the current station.

The platform configured in the traditional way can only support the operation of trains of one specification, and does not support the mixed operation of trains of multiple specifications, resulting in reduced flexibility in the use process, which is not conducive to the subsequent planning and construction of smart cities
