Metro Screen Door Control Method

Abstract

The invention provides a subway shielding gate control method. The subway shielding gate control method is characterized by comprising the steps that running modes of a subway shielding gate control system are set into a normal running mode, an abnormal running mode and an emergency running mode, and when the control system is in the normal running mode, opening and closing of a subway shielding gate are controlled through an automatic system control mode; when the control system is in the abnormal running mode, opening and closing of the subway shielding gate are controlled through a platform level control mode; when the control system is in the emergency running mode, opening and closing of the subway shielding gate are controlled through a manual operation mode; under the situation that a control power source is powered off, normal gate opening and closing can be achieved; when the emergency situation happens and a safety loop cannot be transmitted to a signal system, only a manual bypass key switch on a PSC panel needs to be rotated, emergency braking of a train can be avoided, and therefore railway paralysis is avoided.

Description

technical field [0001] The invention relates to the traffic field, in particular to a method for controlling a subway screen door. Background technique [0002] With the rapid development of the subway and the advancement of information technology, the subway screen door PSC (platform screendoor central control panel) is used as a barrier for passengers to wait for the bus to protect the safety of every passenger. However, even if the screen door is installed, there may be Accidents happen, so it is very necessary to carry out the research on the safety-critical control technology of the screen door system. In 2002, Beijing Subway Company used screen door products and its safety monitoring system for the first time in China, but the relevant technologies at that time were all dependent on foreign countries. At present, the same type of foreign products only display the collected signals in time sequence, without real-time monitoring. processing to form a fault diagnosis exp...

[0002] With the rapid development of the subway and the advancement of information technology, the subway screen door PSC (platform screendoor central control panel) is used as a barrier for passengers to wait for the bus to protect the safety of every passenger. However, even if the screen door is installed, there may be Accidents occur, so it is necessary to carry out research on the safety-critical control technology of the screen door system

In 2002, Beijing Subway Company used screen door products and its safety monitoring system for the first time in China, but the related technologies at that time were all dependent on foreign countries. At present, the same type of foreign products only display the collected signals in sequence without processing to form a fault diagnosis expert system

However, existing products can only operate normally when the power supply is normal. In the case of CPS (control power supply) power failure, the door cannot be controlled to open and close; signal) to the signal system
