Subway shielded door monitoring devices
Technical Field
The utility model relates to a control field especially relates to a subway shielded door monitoring devices.
Background
The subway screen door is also called platform door or safety door, and is a totally-enclosed glass door installed at the edge of a platform to separate the platform from the track. After the subway train enters the station and stops stably, the shielding door can be automatically opened along with the subway train door, so that passengers can get on or off the station.

The action of the shield door is dually controlled by a plurality of devices on the station signal side and a plurality of devices on the electromechanical side. Therefore, the reliability of the operation thereof depends on whether or not the respective devices on the signal side and the electromechanical side can be reliably connected and reliably operated. The reliability of the two devices depends on the daily detection, maintenance and maintenance conditions of the two personnel on the respective devices. When a certain device breaks down, the shield door can not normally act, and faults of not opening the door, not closing the door, slow action, not arriving at the position and the like occur.
After the shielding door breaks down, whether a fault point can be found as soon as possible and repaired as soon as possible needs monitoring equipment with excellent performance. The existing monitoring device only carries out macroscopic monitoring, does not specifically control each relevant device of the shielding door, and does not give out which device fails to cause action failure of the shielding door when the shielding door cannot be normally opened and closed. So that the fault is difficult to be eliminated quickly and troubles are caused for safe driving in a right spot. Meanwhile, because the specific equipment with faults is not positioned, two workers on the signal side and the electromechanical side can tear skins of each other. The utility model discloses the subway shield door monitoring devices who develops can monitor all controlgear of subway shield door, when the shield door breaks down, can direct location to the equipment that breaks down in signal side still electromechanical side to can direct location to specifically that equipment has taken place the trouble. So that maintenance personnel can quickly repair or replace the faulty equipment and restore the normal use of the shielding door as soon as possible.
