Abstract
The invention provides a high-security and maintainability control logic circuit for a shielded door, which is characterized by comprising an opening command relay module, a closing command relay module and a protection circuit, wherein a signal output/input terminal of the opening command relay module is correspondingly connected with a signal input/output terminal of the closing command relay module, a first signal output terminal of the protection circuit is connected with a signal input terminal of the opening command relay module, and a second signal output terminal of the protection circuit is connected with a signal input terminal of the closing command relay module. The high-security and maintainability control logic circuit has the advantages of reducing parts, avoiding excessive separating components, dispensing with manually installing a large quantity of relays parallel wiring, improving shock resistance, dust resistance, water resistance and other tightness of equipment, reducing fault points, adopting redundancy design in an internal circuit, not affecting normal operation of a system in case of single point failure, being capable of discovering and repairing the single point failure rapidly, and achieving convenient use, high security and high reliability.
Description
Technical field
What the present invention relates to is a kind of shield door control logic circuit of high security ease for maintenance, belongs to the track traffic technical field.
Background technology
The control of platform screen door is for the consideration of safety, require to adopt the hard wire logic mode to realize the control of switch door order, these control commands are key signals, when requiring design reliability and safety are placed above the other things, even when breaking down, can find rapidly and repair.
Existing platform screen door control logic circuit state of the art is: adopt the relay that separates to form, but be installed on the base of the wiring that is defined in metal guide rail the loaded down with trivial details fallibility of wiring; After service time was long, vibration and dust all easily caused fault; Be difficult to add holding circuit; And fault location and safeguard that required time is long; Switch gate control order realizes by single relay, by the coil or the contact of single relay, forms key control loop, and risk is concentrated relatively, and the action situation of relay do not have monitoring, even break down, can not in time alarm.
Summary of the invention
What the present invention proposed is a kind of shield door (rail traffic platform shield door) control logic circuit of high security ease for maintenance, and its purpose is intended to overcome the above-mentioned defective of existing in prior technology, and this control circuit has easy to use, and is safe and reliable.Adopt integrated design, the required relay assembly of rail traffic platform shield door switch gate control order is got up, be welded on a bar printing wiring board; All control command loops adopt redundant mode to design; All participate in the relay of control output one group contact are drawn, and use for outer monitoring; The contact of all relays and coil increase holding circuit, prevent overvoltage, and abnormal conditions such as overcurrent damage device.
Technical solution of the present invention: it is characterized in that comprising open the door order relay module, close the door order relay module, holding circuit; wherein open the door corresponding joining of signal I/O end of signal output/input with the order relay module of closing the door of order relay module; first signal output part of holding circuit joins with the signal input part of the order relay module that opens the door, and the secondary signal output of holding circuit joins with the signal input part of the order relay module of closing the door.
Advantage of the present invention: part reduces, and no too much separating component need not artificial install a large amount of relay and wiring, the shock resistance of equipment, and sealing performancies such as dustproof and waterproof are improved, and have reduced the trouble point, when breaking down, can change rapidly; Internal circuit adopts Redundancy Design, and Single Point of Faliure does not influence the normal operation of system; It is all monitored that each participates in controlling its action of relay of exporting, and can be used for the alarm indication that fault takes place, and is convenient to quick reparation, avoids the extension of fault effects, and this control circuit is easy to use, and is safe and reliable.
Description of drawings
Accompanying drawing 1 is the structural representation of shield door logic control circuit.
Accompanying drawing 2 is switch gate control order schematic diagrams, Fig. 2-the 1st wherein, order input circuit 1 schematic diagram that opens the door, Fig. 2-the 2nd, order input circuit 2 schematic diagrams that open the door, Fig. 2-the 3rd, switch door order output principle figure.
The specific embodiment
Contrast accompanying drawing 1; its structure be comprise the order relay module that opens the door, close the door order relay module, holding circuit; wherein open the door corresponding joining of signal I/O end of signal output/input with the order relay module of closing the door of order relay module; first signal output part of holding circuit joins with the signal input part of the order relay module that opens the door, and the secondary signal output of holding circuit joins with the signal input part of the order relay module of closing the door.
Adopt integrated design, the required relay assembly of shield door switch gate control order is got up, be welded on a bar printing wiring board; All control command loops adopt redundant mode to design; All participate in the relay of control output one group contact are drawn, and use for outer monitoring; The contact of all relays and coil increase holding circuit, prevent overvoltage, and abnormal conditions such as overcurrent damage device.
Open the door relay module and closed relay module is relatively independent, has only driving constant close contact separately to insert in the other side's the input circuit.Holding circuit is connected on the contact of relay or and receives on the coil.
Described order relay module or the order relay module that opens the door of opening the door is made up of 4 relays, the open the door relay of order of 2 receptions, and its coil is separate, but mode in parallel is adopted in the contact, 2 relays that send the order of opening the door, its coil is separate, and its contact is parallel with one another.
As Fig. 2-1 and Fig. 2-2, adopt two-way open the door command input circuit, redundancy backup each other; As Fig. 2-3, adopt two-way open the door order output circuit, redundancy backup each other; And the series connection order input contact of closing the door in the order input circuit that opens the door making open the door input and the input of closing the door form mutual exclusion, avoids occurring providing simultaneously the abnormality of the order and the order of closing the door of opening the door.Same for the circuit design principle of the order of closing the door with the upward-acting door command circuit.
The course of work: import the command signal of opening the door as the outside, then drive the two-way order input relay coil that opens the door respectively, its constant close contact is disconnected, the constant open contact closure, then two-way opens the door and drives the coil closure of relay, its constant close contact is disconnected, and the constant open contact closure is exported the order of effectively opening the door; As the outside input command signal of closing the door, then drive the two-way order input relay coil of closing the door respectively, its constant close contact is disconnected, the constant open contact closure, then two-way is closed the door and is driven the coil closure of relay, and its constant close contact is disconnected, the constant open contact closure is exported the order of effectively closing the door.
