Detailed Description
The above objects, features and advantages of the present invention will be more clearly understood and the present invention will be explained in more detail with reference to the accompanying drawings 1 to 3 and the detailed description thereof.
The model of the single chip microcomputer adopted in the embodiment is MSP430, and the change-over switch 1, the in-place travel switch 2, the locking travel switch 3 and the motor 7 are respectively connected with the single chip microcomputer. One end of the pull rod 4 is connected with the change-over switch 1, the transmission mechanism 9 is connected with the chain 5, and the gear mechanism 8 is connected with the chain 5 through a shaft.
The three-station isolating switch closing button is connected with a pin 1 of the single chip microcomputer, the three-station isolating switch opening button is connected with a pin 2 of the single chip microcomputer, the three-station isolating switch grounding opening button is connected with a pin 3 of the single chip microcomputer, and the three-station isolating switch grounding closing button is connected with a pin 4 of the single chip microcomputer. The on-position contact of the change-over switch is connected with the No. 5 pin of the singlechip, the off-position contact of the change-over switch is connected with the No. 6 pin of the singlechip, and the ground potential contact of the change-over switch is connected with the No. 7 pin of the singlechip. The manual locking switch S1 is connected with the No. 8 pin of the single chip microcomputer, the in-place travel switch S2 is connected with the No. 9 pin of the single chip microcomputer, and the breaker auxiliary normally open contact DL is connected with the No. 10 pin of the single chip microcomputer. The coil of the relay K1 is connected with the alarm pin of the singlechip, the common point 16 of the normally open contact 15 of the relay K1 and the relay K1 is connected with the control center as the background, or the common point 16 of the normally closed contact 17 of the relay K1 and the relay K1 is connected with the control center as the background. The positive pole of motor M in this embodiment is connected with normally open contact 18 of relay K2, and the coil of relay K2 is connected with the power end of singlechip, and the negative pole of motor M is connected with normally open contact 19 of relay K3, and the coil of relay K3 is connected with another power end of singlechip.
