Abstract

The utility model provides a mistaken stopping preventive system for an elevator. The mistaken stopping preventive system comprises the elevator (1). Two weighing sensors (2) are respectively arranged at the left edge and the right edge of the front of an elevator door. Signals of the weighing sensors are transmitted to a computer (3), whether people stand on the weighing sensors and wait for the elevator or not is identified by the computer, and identification signals are generated and are transmitted to a PLC (programmable logic controller) (4) of the elevator. The mistaken stopping preventive system has the advantages that whether people wait for the elevator or not can be judged under the condition that an elevator call button on a certain floor is pressed, so that effective states of call buttons can be controlled, the elevator can be prevented from being mistakenly stopped, the elevator utilization efficiency can be improved, and electric energy utilized by the elevator can be saved; the weighing sensors are properly positioned, accordingly, elevator utilization order can be standardized, good stance habit of people can be developed when people wait for the elevator, and risks due to the fact that children with weights below specified weights mistakenly utilize the elevator without being accompanied by guardians can be prevented.

Description

The anti-error stop system of a kind of elevator

Technical field:

The utility model relates to the anti-error stop system of a kind of elevator, and particularly one can anti-mistakenly stop, again can specification passenger erect-position, and the elevator device that can also avoid age small children by mistake to take advantage of.

Background technology:

General elevator device on present society, if passenger will be at the riding elevator of a certain floor, the button up or down that only need press elevator can be in the other arrival that wait elevator of elevator door.But when peak load conditions elevator waits for that number is more, when there is the passenger of more wait in especially multiple floors simultaneously, elevator speed can be very slow, and arriving floor required time far away may be longer, and elevator to arrive when floor far away elevator probably fully loaded.If waits for too long, the passenger who waits at floor far away may select to abandon riding elevator, cause the unmanned elevator of waiting for of this floor, and because elevator wait button has been pressed, elevator still can stop at this floor, reduce like this operating efficiency of elevator, wasted the time of elevator passenger, also wasted the electric energy that elevator consumes.

Summary of the invention:

The purpose of this utility model is exactly the problems referred to above that exist for the riding system of universal elevator, provides a kind of elevator anti-error stop system, reasonable in design, and operation is convenient.

Its technical scheme is: the PLC controller and the elevator button that comprise elevator, LOAD CELLS, computing machine, elevator; On limit, left and right, elevator door front, two LOAD CELLS are respectively set, LOAD CELLS is connected with computing machine by signal wire (SW), and computing machine connects PLC controller, and the instruction that PLC transmits according to computing machine is carried out anti-mistakenly stop control to elevator.

The beneficial effects of the utility model are: it is reasonable in design, simple in structure, are easy to install, easy to use, have avoided the mistakenly stop of elevator, thereby have improved the utilization ratio of elevator, save elevator electric energy used.By the setting of LOAD CELLS position, the riding order of all right specification elevator, allows people in the time waiting for elevator, form good erect-position custom in addition.Can also avoid children accompany the inferior elevator of using without guardian, prevent danger simultaneously.It is more and move slowly and install and use in building at peak load conditions that the utility model is particularly suitable for passenger flow volume.

Brief description of the drawings:

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is position views of LOAD CELLS;

In figure: the PLC controller 4 of elevator 1, LOAD CELLS 2, computing machine 3, elevator, elevator button 5, body of wall 6, elevator door housing 7.

Detailed description of the invention:

By reference to the accompanying drawings 1 and accompanying drawing 2, the utility model will be further described:

The utility model comprises PLC controller and the elevator button of elevator, LOAD CELLS, computing machine, elevator.The signal of LOAD CELLS is passed to computing machine, someone stands in and above LOAD CELLS, waits for elevator for computing machine identification, produce identification signal, identification signal sends the PLC controller of elevator to, and the instruction that PLC transmits according to computing machine is carried out anti-mistakenly stop control to elevator.The function that system realizes is: in the time having people to stand in to wait for elevator in LOAD CELLS, computing machine can be learnt the total weight that stands in people in LOAD CELLS, thereby has judged whether that people is waiting elevator.If someone stands in the first-class elevator of sensor, elevator calling button, in significant condition, is pressed call button and can be called elevator so; If nobody leaves and no longer waits for elevator after the people who waits elevator or the elevator such as all presses call button, PLC is placed in disarmed state by internal processes instruction by call button so, the state of button indicating lamp in not working, elevator will not accepted the calling of this floor, do not stop at this floor, in LOAD CELLS, press call button until there is people to stand in.So just realize the anti-mistakenly stop of elevator.

Accompanying drawing 2 is location view of LOAD CELLS, and an elevator is joined two LOAD CELLS, can arrange three LOAD CELLS if two elevators are close to, and the length of the LOAD CELLS in the middle of two elevators can be got two distances between elevator door housing.Sensor is concordant with ground, signal language " riding elevator please patiently be waited in this region " is posted in top, size sensor marks in the drawings, two sensors are concordant with the elevator door housing edge closing on separately respectively by medial side, and the distance between sensor is identical with the width at elevator door housing edge.Passenger must ensure to have at least a people to wait on LOAD CELLS in the time waiting for elevator, so that call button is in significant condition.People, in the time waiting for this elevator, can stand in LOAD CELLS unconsciously, and people have just formed good erect-position and are accustomed in the time waiting for elevator like this, spontaneously accomplish to get on, get off, and reach the object of the riding order of specification elevator.LOAD CELLS can arrange weight threshold in addition, and in the time weighing less than certain value (such as 30kg), no matter whether someone presses elevator calling button, button is all in disarmed state.So just avoid the children below predetermined weight accompany the inferior elevator of using without guardian, prevented danger.

Claims

1. the anti-error stop system of elevator, is characterized in that: the PLC controller and the elevator button that comprise elevator, LOAD CELLS, computing machine, elevator; On limit, left and right, elevator door front, two LOAD CELLS are respectively set, LOAD CELLS is connected with computing machine by signal wire (SW), and computing machine connects PLC controller, and the instruction that PLC transmits according to computing machine is carried out anti-mistakenly stop control to elevator.
