Background technology

The shield door platform controller that No. 5 lines of Beijing Metro use is formed control logic by single-chip microcomputer, relay, receive the open and close door order that logical number system sends, handle the back through control logic and exchange control voltage to shielding every machine controller DCU transmission, has electrical box intensity height, sheet material is thick and heavy, the characteristics that the box cover hold-down screw is many, but poor reliability, single-chip microcomputer often breaks down, the platform controller can't send to door machine controller DCU and exchange control voltage, causes the shield door of the whole side in station to open or close.

Summary of the invention

The utility model technical issues that need to address are, overcome disadvantages of background technology, provide a kind of simple and reasonable, own wt is lighter, use the safety relay and the time relay of general high-quality, high stability to be logic element, improve the reliability of shield door platform controller.

Concrete technical scheme of the present utility model is, open the door two point of contact of order of the logical number order safety relay J1 coil closing number system of opening the door, close the door two point of contact of order of the logical number order safety relay J2 coil closing number system of closing the door, safety relay J3 coil connects two point of contact of safety return circuit order; The AC50V and enable the AC50V order of opening the door that shield door platform controller sends to door machine controller DCU by safety relay J5 control, shield door platform controller is controlled by safety relay J4 to the AC50V order of closing the door that enables that door machine controller DCU sends; J1K1, The J5 coil is composed in series the circuit that opens the door;

J2K3 series connection back is in parallel with J4K1, with

J4 is composed in series the pass gate circuit;

J2K2 with J6 series connection, J6K1 with Parallel connection,

J2K2 connects with J3K2, J6K2, J7 coil, and J3K2, J6K2 series connection back is in parallel with J7K1; J4K1, J5K1 also connect the L1 end that exchanges the AC50V power supply, and J5K3 meets L1 and holds, and J4K2, J5K2 also connect the L2 end that exchanges the AC50V power supply, enable the AC50V order to the DCU transmission between J5K1, J5K2, send the AC50V order of opening the door to DCU between J5K2, J5K3.

The beneficial effects of the utility model are, the control logic of urban rail traffic platform shield door platform controller is made up of the safety relay and the time relay, receive the order of opening the door that logical number system sends, handle the back through logical block and send the AC50V order of opening the door to door machine DCU, enable the AC50V order, receive the order of closing the door that logical number system sends, handle the back through logical block and enable the AC50V order to door machine DCU transmission, use general high-quality, the safety relay of high stability, improved the reliability of logical block control function, control logic is simple in structure, the electrical equipment that uses is less, and weight is lighter, and is easy to maintenance.

Fig. 2 is urban rail traffic platform shield door platform controller switches door order reception, sending filter wiring diagram.

The specific embodiment

Open the door two point of contact of order of the logical number order safety relay J1 coil closing number system of opening the door lead to close the door two point of contact of order of the order J2 coil closing number system of number closing the door, and the J3 coil connects a two point of contact of machine safety return circuit order; The AC50V and enable the AC50V order of opening the door that shield door platform controller sends to door machine controller DCU by safety relay J5 control, shield door platform controller is controlled by safety relay J4 to the AC50V order of closing the door that enables that door machine controller DCU sends; When logical number system sends when opening the door order, safety relay J1 gets electric, the J1K1 closing of contact,

The closing of contact, safety relay J5 gets electric, constant open contact J5K1, the J5K2 of J5, J5K3 closure, shield door platform controller sends two-way AC50V order to DCU; When order was closed the door in logical number system's transmission, because this moment, safety return circuit was a low level, safety relay J7 was 0,

Closure,

Closure,

Closure, the J2K3 closure, J4 gets electric, the J4K1 closure, after all sliding doors are closed, the safety return circuit closure, J3 is 1, Disconnect, the J4 dead electricity, J4 is 1 o'clock, J4K1, the J4K2 closing of contact, the platform screen door controller sends to door body DCU and enables the AC50V order of closing the door, and when J3 gets when electric, enables AC50V and becomes AC0V; When sending for logical number when closing the door order, the safety return circuit state is for disconnecting, and J3 is 0,

Closure, J6 gets electric, the self-insurance of the J6K1 closing of contact, after the order of closing the door sent for 3.5 seconds, all sliding doors were closed and are locked, and safety return circuit is a path, and the J3 state is 1, the J3K2 closure, J7 gets electric, the closed self-insurance of J7K1;

Connect with J4, the order that prevents to close the door is sent, and after all sliding doors were closed and locked, safety return circuit is unexpected to be disconnected back shield door platform controller and send to DCU and enable the AC50V order of closing the door.The use of safety relay J7 can prevent that the mistake of enable command from sending.
