Detailed Description
In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the present invention will be described in further detail with reference to the following embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1-2, the platform door and door clearance foreign matter detection system controlling means that this embodiment provided, including 1KVA isolation transformer, UPS, isolator group, power module, industrial computer display screen, reserve laser radar, end door display radar, laser radar main control system and laser scanning intelligent control unit, the external 380V three phase current of 1KVA isolation transformer, 1KVA isolation transformer output 220V power to UPS, UPS electric connection isolator group, isolator group electric connection power module and industrial computer display screen, power module electric connection reserve laser radar, end door display radar and laser radar main control system.
In this embodiment, as shown in fig. 1 and 2, an intermediate relay KM2 is added to the shield door PSC cabinet to provide a door locking contact for a laser system to perform scanning judgment, and the laser system should collect and display each state change of KM2 through an interface;
when the screening door lock signal takes place to flash, 400 ms's filtering time should be added to laser system, guarantees that door lock signal disconnection 400ms is in order, and laser system need not scan again and keep closed contact for the screening door system to guarantee KT 1's delay function.
The relay resistor PK is a foreign matter detection signal, and the switch contact is a normally open contact.
The relay resistor PK1 is always in a pull-in state before the train does not enter the station, so that the situation that the safety loop is disconnected due to the fault of the relay resistor PK and the train cannot enter the station is prevented; when a train enters a station, all the station doors are opened, and the PK1 contact springs open; when the train completely leaves the station, the contact of the resistor PK1 is closed.
The working principle of the safety loop is as follows:
when the train is not in the station and the platform door is opened, the laser foreign matter function is always detected but does not output a detection result. The relay resistor PK is in an electrified attraction state; when the platform door is opened, the coil of the relay resistor PK1 loses power, and the contact is flicked.
And detecting the locking signal of the platform door in real time.
If the foreign matter is not detected within the set range of the foreign matter detection system, the relay resistor PK coil is electrified, the contact is closed, the safety loop is conducted, and the train can normally leave the station. After the train completely leaves the station, the coil of the resistor PK1 is electrified, and the contact is closed.
If the foreign matter is detected within the set range of the foreign matter detection system, the relay resistor PK coil loses power, the contact pops open, the safety loop is disconnected, the train cannot leave the station, and the foreign matter is removed after manual confirmation in the station. When the foreign matter is removed and the system cannot detect the foreign matter, the relay resistor PK coil is electrified, the contact is closed, the safety loop is conducted, and the train can normally leave the station. After the train completely leaves the station, the coil of the resistor PK1 is electrified, and the contact is closed.
When the foreign matter detection system breaks down, the one-side main bypass switch on the end door display is switched through, the one side of the system is isolated, the safety loop is physically conducted, and the normal train entering and leaving are not affected.
A UPS-resistor PK relay is added, a normally closed contact is connected to a safety loop, when the foreign matter detection system works normally, a coil of the relay is electrified, the normally closed contact bounces open, and the connected safety loop is disconnected; when the external power supply of the foreign matter detection system is disconnected, the UPS starts to work, and meanwhile, the end door display and the display in the control cabinet prompt that the external power supply is abnormal, and a maintenance worker is required to check. Until the UPS battery is exhausted, the foreign matter inspection system is closed, the relay UPS-resistor PK coil loses power, the normally closed contact connected into the safety loop is closed, the safety loop is conducted, and the normal train entering and leaving are not influenced.
In this embodiment, reserve lidar, end door display radar and lidar control host computer electric connection laser scanning intelligent control unit.
