Abstract
The invention discloses a control method of an intelligent low-pressure drawer unit system. The control method is characterized in that a servo motor is controlled by an infrared manner to rotate clockwise and anticlockwise according to the single-chip microcomputer principle, so as to keep a drawer unit in the existing and exiting state, and the drawer running position is accurately positioned and monitored; in case of power failure or electrical accident, a backup power supply is put into use, a single-chip microcomputer controls the servo motor to rotate anticlockwise and a drawer is automatically ejected out to reach the original position, so as to realize full-automatic intelligent control; the drawer working information can also be fed back to a remote control terminal, thus the failure information can be timely found out, and the drawer can be controlled to exist and exit through a background remote terminal. With the adoption of the control method of the intelligent low-pressure drawer unit system, the drawer unit can freely exist and exit; the motor-based control mode is carried out, the motor lead-screw driving is selected as the main process, the linear motion is performed, thus the fit clearance is small, and little shaking is caused; the automatic driving avoids forced operation, and therefore, the service life of the drawer unit is also prolonged; the remote control function is realized through background remote terminal control software.

Embodiment
Referring to Fig. 2, a kind of intelligent type low-voltage drawer unit system control method, specifically comprises the following steps:
(1), first the drawer unit of making 5 is placed into home position, then send instruction to single-chip computer control system 2 by infrared remote controller 1, single-chip computer control system 2 sends forward instruction to servomotor 4, now servomotor 4 forwards, and drives drawer unit 5 enters in cabinet;
(2), drawer unit 5 enters after cabinet, in the time of 6 indicating correct of the experiment position of circuit breaker, servomotor 4 stops forward, and by after relay time delay 10S, servomotor 4 continues forward, and drives drawer unit 5 enters service position, and makes breaker closing arrive service position;
(3), drawer unit 5 arrives behind service position, in the time of 8 indicating correct of the service position of circuit breaker, drawer unit 5 enters normal operating conditions, now servomotor 4 stops, otherwise, when indicate when incorrect the experiment position 6 of circuit breaker or service position 8, send reversion by infrared remote controller 1 and exit maintenance instruction to single-chip computer control system 2, single-chip computer control system 2 sends reversion instruction to servomotor 4, now servomotor 4 reverses, drives drawer unit 5 exits cabinet, after servomotor 4 stops, carrying out fault eliminating;
(4), pending fault get rid of after, again send instruction to single-chip computer control system 2 by Infrared remote controller 1, repeat above-mentioned steps, until drawer unit 5 enters service position, servomotor 4 is out of service.
Drawer unit 5 is in normal course of operation, can directly send servomotor reversion instruction to single-chip computer control system 2 by infrared remote controller 1, servomotor 4 is reversed, and from isolated location 7, drawer unit 5 is exited, servomotor 4 stops, if drawer unit 5 exit in process meet with obstruction, clamping stagnation or other faults, can directly manually exit, and carry out fault eliminating.
The present invention can also replace infrared remote controller 1 by remote control terminal 3 and send instruction to single-chip computer control system 2, and carry out the rotating of self-inspection and control servomotor 4 by above-mentioned steps (1), (2), (3), (4), thereby drives drawer unit 5 enters and exits cabinet.
Said method can make drawer unit 5 freely enter and exit, and owing to adopting Electric Machine Control mode, selecting motor screw rod transmission is main procedure, the rectilinear motion adopting, fit clearance is little, and rocking property of transmission process is little, rough power operation, the useful life of having improved drawer unit 5 have been avoided in automation transmission; Remote terminal control software by backstage has been realized remote control function; If but break down in distribution scene or distribution system voltage instability, the in the situation that of dead electricity, circuit breaker automatic trip, but primary circuit is still in connected state, at this moment start stand-by power supply 9, stand-by power supply 9 provides power supply to single-chip computer control system 2 and servomotor 4, single-chip computer control system 2 sends reversion instruction to servomotor 4 simultaneously, servomotor 4 reverses, by drawer unit 5 automatic springs, effectively prevent after dead electricity the moment loss causing of sending a telegram here, effectively reduced the risk that second accident occurs.
Referring to Fig. 3, by Single Chip Microcomputer (SCM) system control electric chassis, drive drawer unit to do front and back rectilinear motion by arrow shown in Fig. 3 by the transmission of screw mandrel slide rail, operate steadily, without rocking, Electric Machine Control is flexible, each position is accurate, power-off is exited freely flexible, has reached object of the present invention.
By above-mentioned control method, solve in current drawer control procedure and run into by the clearance issues coordinating and cause rocking property of drawer unit large, quite the operation of power makes drawer unit damage and cannot normally work, the drawer unit breaking down cannot automatic spring, increase the problem of the risk of second accident, solved the problem that the use and maintenance of drawer unit all needs artificial scene to carry out simultaneously, can directly pass through Background control, realize Long-distance Control, reduce field management expense, the application of control method of the present invention can not only substitute drawer control unit in the market, more drive the once huge progress of power distribution cabinet industry.
