For example: the A1 pin of the relay ADCL1 is connected to the +24V power supply, and the A2 pin is connected to the 0V power supply; a DCU24#, DCU23#, DCU2# and DCU1# are connected in series between the A1 pin and the power supply +24V in sequence; DCU24#, DCU23#, DCU2# and DCU1# are connected in series between A2 pin and power supply 0V in sequence. The coil of relay ADCL2 is connected in parallel with the coil of relay ADCL 1.

When the relay ADCL1 works, the normally closed contact in the relay ADCL1 is closed, the relay ADCL1 is communicated with the SIG signal processing system, and the SIG signal processing system receives signals, so that the user knows that a door is opened, and then acts. For example, when a train does not yet enter the station, the SIG signal processing system receives a signal to notify the train to stop entering the station by detecting that a door is opened. The connection mode of the relay ADCL1 can be that the 14 pin and the 8 pin of the relay ADCL1 are connected to the SIG signal processing system, the 13 pin of the relay ADCL1 is connected to the power supply 0V, and the 7 pin of the relay ADCL1 is connected to the power supply + 24V.

In the above-mentioned realization process, can monitor the full-open and the full-closed state of platform door through setting up the safety circuit to when the abnormality appears in the full-closed state, in time let SIG signal processing system receive the high level signal, thereby learn to appear unusually, and then in time make the action, avoid appearing dangerously, guaranteed driving safety.

The interlocking release switch is connected with the relay PIO in parallel, and the relay PIO is connected with the SIG signal processing system in parallel. The normally open contact of the relay PIO is connected in parallel with the SIG signal processing system, and the interlock release switch may be a key interlock release switch. When the interlocking contact key is pressed on the PSL-H operating platform, the wire coil of the relay PIO is electrified, the normally closed contact of the relay PIO is closed, and the SIG signal processing system receives a high-level signal, so that the interlocking contact is known. When the interlocking contact key on the PSL-H operating platform is invalid or under other conditions, the interlocking contact key can be released through the interlocking release switch, and after a circuit in the interlocking release switch is conducted, the SIG signal processing system receives a high-level signal, so that the interlocking contact can be known. For example, pin 8 and pin 10 of relay PIO are connected to the SIG signal processing system, pin 9 of relay PIO is connected to power supply 0V, and pin 7 of relay PIO is connected to power supply + 24V. Two ends of a first interlocking contact switch in the interlocking release switch are respectively connected with a pin No. 9 and a pin No. 10 of the relay PIO, and two ends of a second interlocking contact switch in the interlocking release switch are respectively connected with a pin No. 8 and a pin No. 7 of the relay PIO.

In the implementation process, the interlocking release circuit is arranged, so that when the interlocking contacts, the SIG signal processing system can timely learn and timely make action, and the driving safety is ensured. Meanwhile, the interlocking release switch is arranged, so that the interlocking unlocking operation can be carried out without a PSL-H operation table, the SIG signal processing system can know timely and act timely, and the driving safety is ensured.
