Technical field

The utility model relates to the used control setup of a kind of elevator, belongs to the elevator field.

Background technology

In the prior art, general elevator taken the back car just can be parked in the passenger that takes at last that layer down, make elevator all be in the bottom through regular meeting so perhaps all at high level.When all being in bottom, high-rise people wants to do elevator and gets off and just need wait for a long time, and takes elevator simultaneously and has arrived the bottom elevator and can be stopped at bottom again, and the next bit high level wants the passenger who gets off still need wait for for a long time; When equally all being parked in high level, the people of bottom wants to take elevator and upstairs also need wait for for a long time.When this situation usually occurred in working, people took elevator downstairs, and elevator is stopped at bottom for a long time; When coming off duty, people's elevator of all going home all is stopped at high level; Just opposite in the office space, take elevator with high-rise people for like this bottom and all in the regular hour section, brought inconvenience.

The utility model content

The purpose of the utility model is, band auto-reset function elevator control device is provided, and it can make elevator automatically reset to top layer and bottom, lets two elevators separately park, and reduces passenger's wait time, for people offer convenience.

The technical scheme of the utility model: a kind of band auto-reset function elevator control device; Comprise that button circuit, coder, Hall element, PLC Programmable Logic Controller, diode memory circuit, PWM control alignment circuit, car switch gate circuit and floor display circuit; Button circuit links to each other with coder and Hall element all is connected on the PLC Programmable Logic Controller; Also be connected with the diode memory circuit on the PLC Programmable Logic Controller, PWM controls alignment circuit, car switch gate circuit and floor display circuit; Be provided with 2～7 sensors in the car and be used to detect car current demand signal state, sensor links to each other with the PLC Programmable Logic Controller.Owing to be provided with sensor; Can and whether exist other instructions to feed back to control system with the present running condition of elevator; Sensor is constantly given the PLC Programmable Logic Controller with signal feedback; Continue to the lift car reset instruction, when not having other instruction to send, the transmission of sensor holding signal stops until the back instruction that resets.

In aforesaid a kind of band auto-reset function elevator control device, be provided with 4 sensors in the car.

In aforesaid a kind of band auto-reset function elevator control device, sensor is set to heat sensitive sensor.Owing to be provided with heat sensitive sensor, it can convert the body heat semaphore of doubly measuring into frequency signal or periodic signal transmission, and is more accurate, concrete, is not only the transmission of position signal.

In aforesaid a kind of band auto-reset function elevator control device, the PLC Programmable Logic Controller is provided with slug relay and plays the effect that signal lag sends.Because be provided with and seen slug relay, elevator resets in the time of can avoiding the passenger to return immediately.

After the out code of car switch gate circuit was sent, when nobody operated button circuit, the sensor in the car passed to the PLC Programmable Logic Controller with the current status information that nobody takes of elevator; The PLC Programmable Logic Controller passes to slug relay with signal, and the PLC Programmable Logic Controller makes slug relay switch on and begins to get into time-delay timing 1～5 minute, in the time-delay process; If nobody operates elevator; When the time-delay timing finishes, slug relay's action, the contacting signal passes to the PLC Programmable Logic Controller; The reset function that edits is accessed, send reset instruction.Owing to use slug relay, can prevent the action of elevator halted state immediate replacement.

Compared with prior art; The utility model is owing to be provided with sensor; Whether can and exist other instructions to feed back to control system with the present running condition of elevator, sensor, continue to the lift car reset instruction with signal feedback if constantly giving the PLC Programmable Logic Controller; When not having other instruction to send, the transmission of sensor holding signal stops until the back instruction that resets; Owing to be provided with heat sensitive sensor, it can convert the semaphore of doubly measuring into frequency signal or periodic signal transmission, and is more accurate, concrete, is not only the transmission of position signal; Because be provided with and seen slug relay, elevator resets in the time of can avoiding returning immediately.The elevator of this band auto-reset function and control method thereof can be when unmanned the use one reset in bottom, one resets in top layer, is that the floor two ends are taken elevator and can not waited for for a long time, time of having saved of going on a journey has brought convenience to people.
