Description
Technical field
The utility model relates to a kind of controlling apparatus for lifts door, especially a kind of automatic floor-levelling control device of elevator.
Background technology
The elevator using in construction at present, adopts manually operated mode to realize lifting, by the lifting of special operating personal hand control elevator car mostly.When needs rise or decline, pin corresponding control button, when reaching a certain floor and need elevator car to stop, unclamp control button., owing to being manual operation, the flat bed of car is usually inaccurate, often needs repeatedly to press control button several times and just can make elevator car substantially be parked in level position.Operating personal is relatively wasted time and energy, and the effect of lift car leveling neither be fine.
Although some unit has also developed some automatic floor-levelling control device for elevators, such as utilizing the control system of gear pulse detection floor height, precision is not high enough, cannot meet in actual applications the requirement of elevator automatic leveling completely.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of automatic floor-levelling control device, the function that possesses study floor height, both can be so that cage operation be automatically parked in this floor after destination after having learnt, and had increased substantially the precision of flat bed.The technical solution adopted in the utility model is:
An automatic floor-levelling control device, comprises master control board, keyboard, is arranged on coder on the gear wheel shaft of elevator, is arranged on the read-out in elevator car; Described master control board connects described read-out, keyboard and coder; Described master control board is also connected with elevator electric controller by the output interface on master control board.
Further, described master control board comprises a pulse zero clearing interface, and this pulse zero clearing interface is connected with the travel switch that is arranged on elevator car bottom.
Further, the output interface of described master control board is built-in with output relay.
Further, described output relay comprises up control relay, the descending control relay that automatically stops of automatically stopping.
Further, described master control board also comprises a remote alarm interface.
Advantage of the present utility model: the utility model makes elevator possess automatic leveling function, and increased substantially the precision of flat bed.The utility model has also possessed zero clearing interface, can eliminate the accumulated error bringing on elevator car downstairs.

The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: a kind of automatic floor-levelling control device, comprises master control board 1, keyboard 2, is arranged on coder 3 on the gear wheel shaft of elevator, is arranged on the read-out 4 in elevator car; Described master control board 1 connects described read-out 4, keyboard 2 and coder 3; Described master control board 1 is also connected with elevator electric controller by the output interface on master control board 1.
Principle of work of the present utility model is as follows: improvements of the present utility model are that coder 3 increasing, coder 3 is arranged on the gear wheel shaft of elevator, rotation along with gear wheel shaft, the number of turns that coder 3 turns over according to gear wheel shaft and angle, output is risen or the corresponding number of pulses of falling head with elevator car.Such as being that 1024 pulses/while turning, if elevator car rises to the second layer from bottom, gear wheel shaft has turned over M circle when coder 3 resolution, the quantity of coder 3 output pulses is 1024*M.If elevator car rises to the 3rd layer from the second layer, gear wheel shaft has turned over N circle, and the quantity of coder 3 output pulses is 1024*N.Master control board 1 can be recorded the corresponding coder 3 output number of pulses of each floor height (being height between contiguous floors), the foundation of output and the corresponding control signal of floor height during as operation.
As shown in Figure 3, at this device, be installed in a new engineering, before putting into operation, need to first remove floor height record (record in the time of may having the record in other engineering in device or dispatch from the factory test), then carry out floor height study.When elevator car is parked in bottom, remove the operation of floor height record, detailed step is as shown in Figure 4.After completing illustrated steps, floor height record is eliminated.
The operation of floor height study as shown in Figure 5, specifically, M/C (can keypad 2 ↑ key), make elevator car from bottom toward rising, when being raised to the second layer, (passed through first floor height), press numerical key " 1 ", then press "enter" key", the corresponding coder 3 output number of pulses of first floor height are learned in master control board 1; Manual lifting again, every one deck all stops, and learns, until top layer can all be succeeded in school all floor heights.
After floor height study finishes, this device can drop into real-world operation.Master control board 1 can be according to the floor of current stop, and the destination that will arrive, calculate corresponding number of pulses, send the control signal corresponding with the number of pulses of calculating, this control signal passes to elevator electric controller, controls drive motor and drives elevator car to run to destination.As long as operator is by keyboard 2 input destinations number, master control board 1 will be according to elevator car current location with respect to the floor that will arrive, output corresponding control signal is to elevator electric controller, and then elevator car can automatically reach destination and stop under drive motor drives.
Sometimes because some reason (such as load-carrying in car is overweight), the corresponding control signal of number of pulses that send according to master control board 1 and that calculate, car may not can be just parked in destination, but than destination low several centimetres of zero points; While next moving across floor, if same reason also exists, the error of car and next destination will be accumulated on the basis of a upper error so.This can cause car always not concordant with destination, need on operation keyboard 2 ↑ key or ↓ key carries out the concordant operation of manual floor.For avoiding the continuous accumulation of car and floor error, on master control board 1, designed a pulse zero clearing interface, the travel switch 5 normally closed contact input reset signals of installing by elevator car bottom are to this pulse zero clearing interface.When elevator car drops to bottom, travel switch 5 normally closed contacts of elevator car bottom are opened, and reset signal just feeds back to master control board 1, to eliminate the accumulated error bringing on elevator car downstairs.Next the operation that master control board 1 starts a new round according to car in bottom position is controlled.
The output interface of master control board 1 is built-in with output relay, comprises up control relay, the descending control relay that automatically stops of automatically stopping.So no matter whether have frequency converter in elevator electric controller, this device can access use easily.
The coder 3 of the utility model configuration, what adopt is the difference teletransmission coder of industry spot application, resolution is 1024 pulses/turn, when coder 3 damages or when user need to alternate coding device according to the demand of oneself, if new coder and original encoding device resolution are inconsistent, need to carry out replacing flow process as shown in Figure 6.Encoder resolution need to be set in this layers control set, then re-start the operation of removing floor height record and floor height study.The operation of encoder resolution is set as shown in Figure 7.
Read-out 4 is arranged in elevator car, can adopt LED display.
