Description
Technical field
The utility model relates to a kind of double loop door lock detecting device be applied in elevator controlling.
Background technology
Existing door lock of elevator detecting device only has a standard door lock measure loop usually, and each layer door lock of whole elevator is connected by one by one, is finally input to control desk or the frequency converter of apparatus for controlling elevator.This door lock detecting device safety is lower, and when certain layer of door lock et out of order, its cascaded structure cannot determine the particular location that fault occurs fast, for maintenance is made troubles.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly improves safety and the double loop door lock detecting device of easy access.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of double loop door lock detecting device, be connected with the control system of elevator, it comprises and the standard door lock measure loop established and communication door lock measure loop; Described standard door lock measure loop comprises door lock and the switching device of each layer elevator door be in series; Described communication door lock measure loop comprises the door lock state that detects each layer elevator door respectively and the detecting device connected with signal with the control system of elevator.
Described detecting device is connected with the control system of elevator by 232 or 485 communication devices.
Described detecting device is arranged on the calling plate of each layer of elevator.
Described standard door lock measure loop and communication door lock measure loop are connected with the master control board of apparatus for controlling elevator or frequency converter respectively.
Described switching device is contactless switch or relay.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model adopts two door lock measure loop, better ensure that the safety performance of door lock of elevator mechanism, and when door lock breaks down, the part that goes wrong can be determined rapidly, for maintenance provides a great convenience by communication door lock measure loop.
Accompanying drawing explanation
Accompanying drawing 1 is the principle schematic of double loop of the present utility model door lock detecting device.
Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment one: shown in accompanying drawing 1, a kind of double loop door lock detecting device, is connected with the master control board of the control system of elevator or frequency converter MCB/INV.This double loop door lock detecting device comprises and the standard door lock measure loop established and communication door lock measure loop.Standard door lock measure loop comprises door lock LD and the switching device KM of each layer elevator door be in series, and wherein switching device KM is contactless switch or relay.Communication door lock measure loop comprises the state of the door lock LD detecting each layer elevator door respectively and the detecting device connected with signal by 232 or 485 communication devices with master control board or the frequency converter MCB/INV of the control system of elevator, and detecting device is arranged on the calling plate HCB of each layer of elevator.
Above-mentioned double loop door lock detecting device better ensure that the safety performance of the whole door lock mechanism of elevator by 2 door lock measure loop.Can accurately be located in an elevator by the communication-type door lock measure loop of outer-office calling plate is which layer door lock goes wrong, and especially in the elevator of high-storey, can provide convenient greatly for orientation problem or maintenance.Article 2, the redundancy detection mode in loop adapts to various criterion all over the world, meets the different requirements detected for door lock.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
