Principle of the present invention is: through logic relay action emulation to relay 64D semiautomatic loading mechanism, and the logical relation of 13 relays of simulation.And the micro controller system between two stations can be realized the information transmission of the process of handling directly through serial communication, has removed the link of opto-electronic conversion from, has reduced the trouble point.

When serial ports was idle between two stations, mutual sendaisle check code was according to the mode of operation of both sides' semiautomatic loading mechanism; Select different passage check codes, not only checked the state of passage, and through different check codes; Both sides can know the other side's mode of operation, are to kill two birds with one stone.

Check code is following coding:

1, the initial condition both sides are to sending out passage check code [initial check code 10000000]

2, after [request departure signal+→ 11000000] were sent and accomplished, tours start here was sent out [check code 10100000], connects the station and sends out [check code 10110000]

3, after [automated response piece signal-← 10111000] sent and accomplish, tours start here was sent out [check code 10110100], connects the station and sends out [check code 00100010]

4, after [signal of accepting a train+← 11110000] were sent and accomplished, tours start here was sent out [check code 10110110], connects the station and sends out [check code 00110000]

5, after [train departure's signal+→ 01010010] was sent and accomplished, tours start here was sent out [check code 00000000], connects the station and sends out [check code 00100110]

6, [arrive release signal-← 00101110] and send after the completion, both sides' equipment resets into initial condition, and the sending and receiving both sides are to sending out a passage check code [initial check code 10000000].

The present invention compared with prior art, its remarkable advantage is:

1) the present invention adopts digitizing technique, has simplified interior communication, has improved the reliability of interior communication;

2) the present invention adopts photoelectric isolation technology, when passage receives serious interference, can not exert an influence to circuit, guarantees can not produce harmful effect to the normal operation of existing station interlocking;

3) the present invention has reduced the opto-electronic conversion link, has reduced the trouble point;

4) this micro controller system 64D semiautomatic loading mechanism can be to transmission path between the station, and real-time oversight discovery access issues can in time be reported to the police, and reduces the generation of breakdown of equipment.

Below in conjunction with accompanying drawing the present invention is described in further detail.
