Abstract
The invention provides a sundry elevator control system and belongs to the field of elevators. The invention provides a sundry elevator control system based on a PLC (Programmable Logic Controller). The sundry elevator control system mainly consists of an operation control board of each floor as well as a main PLC and a motor dragging system, wherein the operation control board of each floor consists of input signals of a call button, an emergency stop switch and the like of each floor, and output signals of elevator ascending and descending indication lamps, a nixie tube floor display, an emergency stop indication lamp, a door opening indication lamp, a floor call indication lamp and the like. The input signals and output signals of the operation control board are respectively connected with the input interface and output interface of the PLC, so as to form a control system. In order to ensure the safety of working personnel, an emergency stop button is designed, after an elevator arrives at a target floor, the emergency stop button is pressed down, other button-pressing operations are invalid, so that the working personnel can conveniently control the stop time of the elevator. The sundry elevator control system has the advantages of simple structure, low cost, stability, safety and reliability.
Description
Technical field
The present invention relates to elevator field, especially a kind of novel sundries elevator control system based on PLC.
Background technology
In building ground, tiered warehouse facility, it is many that each floor gap transports material goods etc., and it is relatively long to enter Cargo Lift handling time, and other floor staff carries out call operation, and elevator motion has certain potential safety hazard to the staff who is carrying.At present, sundries elevator control system is adopted in two ways substantially: the one, and microcomputer, as signaling control unit, completes collection, running state and the function setting of elevator signal, realizes the operation function of elevator.The 2nd, adopt Programmable Logic Controller (PLC) to realize signal control.The computer control device design cycle is long and manufacturing cost is high, is unfavorable for widespread use, and the advantage such as PLC reliability is high, and program design is convenient, flexible, and antijamming capability is strong, stable can directly be bought.So, to be badly in need of a kind of staff and when transporting goods, can to control safely and effectively elevator at the device of floor standing time, this apparatus structure is simple, cost is low, stability and safety is reliable, has become urgent problem.
Summary of the invention
According under above-mentioned background, the object of the present invention is to provide a kind of simple, safe and reliable, practical sundries elevator control system based on PLC.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the present invention has adopted following technical scheme:
A sundries elevator control system based on PLC, the main operation control panel by every floor and master controller PLC and motor driving system form.
Floor operation control panel is composed as follows by incoming signal and output display signal:
Incoming signal has: each floor call button, emergency stop switch etc.; Output signal has: elevator up-down indicator lamp, charactron floor show, anxious indicator lamp, the opening indicating lamp of stopping; The incoming signal of operation control panel is connected with output interface with the input interface of Programmable Logic Controller respectively with output signal, forms a control system.
Floor operation control panel is placed on by elevator doorway, and in elevator, without operation control panel, this invention system is that groceries are special-purpose, can not be manned.
Because goods is in handling process, elevator standing time is relatively long, and in staff's handling process, elevator is not movable, for guarantee staff safe design scram button, elevator arrives after object floor, press scram button, other push-botton operation is invalid, after portage completes, close floor door, recover scram button, other call button operation is just effective, is convenient to staff and controls elevator standing time.
Electric light in elevator connects the output interface of Programmable Logic Controller (PLC), by PLC setting program, presses scram button, and when goods elevator door is opened, the electric light in elevator is bright, and door is turned off the light and extinguished, power saving, easily and effectively.
Advantage of the present invention be simple in structure, cost is low, stability and safety is reliable.The present invention is for the needs of Cargo Lift safety control, adopts Programmable Logic Controller (PLC) to carry out master control, on the satisfied basis of function, also designs some additional functioies as controlled electric light in elevator etc.
Accompanying drawing explanation
Fig. 1 is four layers of sundries elevator control system block diagram based on PLC of the present invention.
Fig. 2 is floor operation control panel.
Fig. 3 is PLC constructional drawing.Input port and output port
Fig. 4 is elevator plan sketch.
The specific embodiment
Press the floor call button that will go on floor guidance panel, by positive and inverse rotation of relay controlled motor, make elevator up-down, corresponding elevator up-down indicator lamp is bright, arrives the floor that goes, must press scram button, suddenly stop display lamp bright, elevator door is opened and is followed opening indicating lamp bright, and in elevator, electric light is bright, staff can carry out portage, after completing, shut elevator door, reset scram button, just can carry out other floor call operation.Pressing scram button, before reset, other push-botton operation is invalid, operates that other is effective by knob after scram button resets, and has guaranteed that like this staff controls the time that elevator stops.
Fig. 4 is elevator plan sketch.1 is upper limit travel switch, and 2 is 4 layers of travel switch, and 3 is 3 layers of travel switch, and 4 is 2 layers of travel switch, and 5 is 1 layer of travel switch, and 6 is lower limit travel switch, and 7 is motor, and 8 is elevator.The input interface of the map interlinking 3PLC that travel switch is corresponding with limit switch difference.Elevator is under the motion of motor, and elevator, with after the contact of corresponding floor travel switch, is controlled motor by PLC and made motor stop motion, and elevator is parked in corresponding floor.
According to elevator input/output point, determining PLC model, is the concrete principle explanation of four layers of dumb waiter below.
1. entrance point estimation: every layer has a call button to amount to 4, every layer has an approach switch to amount to 4, respectively has up and down a limit switch to amount to 2, and 1 scram button, amounts to 11 entrance points.
2. output point estimation: the up-downgoing of elevator is by a direct motor drive, electrical motor is just transferring ascending for elevator to, be reversed to descending 2 output points altogether of elevator, upper and lower run indicator amounts to 2 output points, every layer has a ringing pilot lamp to amount to 4 output points, 1 urgency is stopped display lamp, and floor charactron shows needs 3 output points, amounts to 12 output points.
PLC of the present invention does not arrange special machine room, can under various industrial environments, directly carry out, and when practical, only field apparatus need be connected and can move with the corresponding I/O end of PLC.
Every equivalence that the essence of content has been done according to the present invention changes or revises, and all should be encompassed in protection scope of the present invention.
