Abstract
The invention discloses a detecting device used for an elevator and belongs to the technical field of an elevator detecting device. The detecting device used for the elevator comprises a programmable logic controller, a pressure sensor and an alarm device. The detecting device used for the elevator further comprises an infrared sensor and a distance measuring sensor. The programmable logic controller is respectively electrically connected with the pressure sensor, the alarm device, the distance measuring sensor and the infrared sensor. The detecting device used for the elevator is simple in structure and convenient to use. Mistaken overloading reminds delivered by the nonuniformity caused by the fact a person stands are avoided.
Description
Technical field
The present invention relates to a kind of detecting device for elevator, belong to elevator detecting device technical field.
Background technology
The judgement of weighing of existing elevator inside all is equipped with pressure sensor basically below elevator, judge by pressure sensor whether it is overweight, if overweight, just sends voice reminder.But the long-term use due to elevator causes error in judgement, even when not reaching institute's standard volume in ladder, also can send overweight alarm.Find after deliberation, the people in ladder stands when inhomogeneous, also can send overweight alarm, although the elevator period of service has been grown, corresponding load-carrying meeting reduces, but because of the not even overweight warning that causes in station, cause elevator slowly not move, wasted undoubtedly everybody time, also caused the waste on the resource.
Summary of the invention
Problem for above-mentioned prior art exists the invention provides a kind of detecting device for elevator, can effectively address the above problem.
To achieve these goals, the technical solution used in the present invention is: a kind of detecting device for elevator, comprise Programmable Logic Controller, pressure inductor and annunciator, also comprise infrared inductor and distance measuring sensor, Programmable Logic Controller is electrically connected to pressure inductor, annunciator, distance measuring sensor and infrared inductor respectively.
Wherein, Programmable Logic Controller is micro controller system; Annunciator is phonetic alarm.
Principle of work: give in advance corresponding inductor default effective value in Programmable Logic Controller, when elevator stops, pressure inductor detects the weight of elevator at any time, and send institute's measured value to Programmable Logic Controller, distance measuring sensor and infrared inductor also survey at any time the people in ladder relative position and between distance, and will be worth and also give Programmable Logic Controller, only have when these three inductor institute measured values all reach preset value, the elevator lamp overload alarm just sends audio alert sound, the reminding user elevator overload; On the contrary, as long as when wherein any one value does not reach preset value, do not send chimes of doom, avoided the inhomogeneous overload prompting of sending mistake because of the people station.
The invention has the beneficial effects as follows: simple in structure, easy to use, avoided the inhomogeneous overload prompting of sending mistake because of the people station.
Description of drawings
Fig. 1 is electric functional block diagram of the present invention
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes Programmable Logic Controller, pressure inductor and annunciator, also comprise infrared inductor and distance measuring sensor, Programmable Logic Controller is electrically connected to pressure inductor, annunciator, distance measuring sensor and infrared inductor respectively.
Wherein, Programmable Logic Controller is micro controller system; Annunciator is phonetic alarm.
Working process: give in advance corresponding inductor default effective value in Programmable Logic Controller, when elevator stops, pressure inductor detects the weight of elevator at any time, and send institute's measured value to Programmable Logic Controller, distance measuring sensor and infrared inductor also survey at any time the people in ladder relative position and between distance, and will be worth and also give Programmable Logic Controller, only have when these three inductor institute measured values all reach preset value, the elevator lamp overload alarm just sends audio alert sound, the reminding user elevator overload; On the contrary, as long as when wherein any one value does not reach preset value, do not send chimes of doom, avoided the inhomogeneous overload prompting of sending mistake because of the people station.
