Abstract
The utility model discloses an elevator door interlock adhesion or artificial short circuit safety detection device which is characterized by comprising three signal detection devices (3) which are respectively connected with a hall door lock contactor (1), a car door lock contactor (2) and the two ends of a series circuit formed by the contactors, wherein the signal detection devices (3) are connected with an elevator door interlock detection plate (4). By collecting signals of the hall door lock contactor, the car door lock contactor and the series circuit formed by the contactors, and processing the signals by the elevator door interlock detection plate, the elevator door interlock adhesion or artificial short connection safety detection device can simultaneously monitor the switching on and off situation of an elevator hall door and a car door interlock contactor, and also can judge the artificial short circuit. Furthermore, the elevator door interlock adhesion or artificial short circuit safety detection device has simple structure and lower cost, does not need professional to debug software.
Description
Technical field
The utility model relates to a kind of elevator safety detecting device, particularly a kind of safety detection device at elevator door interlocking adhesion or artificial short circuit.
Background technology
At present the elevator that uses the is complete substantially automatic measuring ability after the gate interlock adhesion, and realize by software detection gate interlock on off mode substantially.But most of elevators can't be at doing real-time effective detection by artificial short circuit gate interlock loop.And elevator will realize that it will be very big detecting required cost in real time, and needing the professional to arrive field change software could realize.
The utility model content
The purpose of this utility model is, the safety detection device of a kind of elevator door interlocking adhesion or artificial short circuit is provided.It can monitor the break-make situation of hoistway door and car door interlock contactless switch simultaneously, and has increased the judgement to artificial short circuit, and simple in structure, cost is relatively low.
The technical solution of the utility model: the safety detection device of a kind of elevator door interlocking adhesion or artificial short circuit, it is characterized in that: comprise three signal supervisory instruments at the circuit series two ends that are connected to Room every latch contact, car door lock contactless switch and above-mentioned contactless switch composition, signal supervisory instrument links to each other with elevator door interlocking check-out console.
The above-mentioned elevator door interlocking adhesion or the safety detection device of artificial short circuit is characterized in that: described elevator door interlocking check-out console comprises A/D converter and the CPU that links to each other with A/D converter.
Compared with prior art, the utility model is by the signal on the circuit series of collecting Room every latch contact, car door lock contactless switch and above-mentioned contactless switch composition, handle via elevator door interlocking check-out console, can monitor the break-make situation of hoistway door and car door interlock contactless switch simultaneously, and increased judgement to artificial short circuit, and simple in structure, cost is relatively low, need not professional's debugging software.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-Room every latch contact, 2-car door lock contactless switch, 3-signal supervisory instrument, 4-elevator door interlocking check-out console.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.The safety detection device of a kind of elevator door interlocking adhesion or artificial short circuit, constitute as shown in Figure 1, three signal supervisory instruments 3 that comprise the circuit series two ends that are connected to Room every latch contact 1, car door lock contactless switch 2 and above-mentioned contactless switch composition, signal supervisory instrument 3 links to each other with elevator door interlocking check-out console 4.Elevator door interlocking check-out console 4 comprises A/D converter and the CPU that links to each other with A/D converter.
Principle of work of the present utility model: according to the structural principle of elevator door-motor drive configuration and door lock, the active door of gate for driving, Room door is a passive door, and the switch operation of Room door is to do the operation of switch door by the door lock ball that the door cutter that is installed on the gate drives on the door of the Room.After door machine driving gate is closed fully, the action of further closing the door along with the door machine, Room door must be in closing fully, this moment, landing interlock could normal engaged, the electric terminal of Room every latch contact 1 must with conducting, answer this in the process that door machine driving Room gate is closed, the electric terminal of gate is connected prior to Room door electric terminal all the time.This is that physical construction by elevator door-motor is determined.Then the door lock action is just in time opposite for the process of opening the door.When Room every latch contact 1 and car door lock contactless switch closure, can produce a positive rise signal, and can judge according to above-mentioned principle, two positive rise signals should be nonsynchronous, if signal supervisory instrument 3 detected signals are synchronous, can be judged as artificial short circuit.And when opening the door, the circuit series that Room every latch contact 1 and car door lock contactless switch 2 formed should be to open circuit, and therefore when signal supervisory instrument 3 detected these circuit are conducting state, can be judged as the elevator door adhesion of interlocking.When above-mentioned two judgements were normal circumstances, elevator door interlocking check-out console 4 can be exported the door lock normal output signal to apparatus for controlling elevator.
Claims (2)
1. the safety detection device of elevator door interlocking adhesion or artificial short circuit, it is characterized in that: comprise three signal supervisory instruments (3) at the circuit series two ends that are connected to Room every latch contact (1), car door lock contactless switch (2) and above-mentioned contactless switch composition, signal supervisory instrument (3) links to each other with elevator door interlocking check-out console (4).
2. the safety detection device of elevator door interlocking adhesion according to claim 1 or artificial short circuit is characterized in that: described elevator door interlocking check-out console (4) comprises A/D converter and the CPU that links to each other with A/D converter.
