Abstract
The utility model discloses an elevator shaft door lock signal processing device comprising door lock signal branch circuits of all floors which are connected parallelly, and a main control board which is used for receiving the output information of the door lock signal branch circuits of all the floors; the door lock signal branch circuit of each floor comprises a door lock switch, a voltage conversion card which is electrically connected with the door lock switch and an external call controller which is electrically connected with the voltage conversion card; and the external call controllers of all the floors are electrically connected onto the main control board according to a communication protocol. The door lock switches of all floors are respectively connected into the voltage conversion cards of the corresponding floors, the output of the voltage conversion cards is connected into the external call controllers of the corresponding floors, so that the door lock signals of all floors can be transmitted to the main control board through the external call controllers according to the communication protocol; and the main control board refers to the communication protocol and can obtain the status information of the shaft door locking switches on all floors by identifying the received floor numbers of signal data, so that repair and commissioning are facilitated, and safety hidden hazard is eliminated.
Description
Technical field
The utility model relates to elevator door door lock signal processing equipment.
Background technology
The layer door of elevator is the part that passenger or user at first touch when riding elevator, and its effect is the gangway of sealing the floor hoistway, and the assurance personnel do not contact avoid falling hoistway or shearing accident with parts in the hoistway on floor.The layer door of elevator is the multiple area of injury accident, so a layer safe operation to elevator plays a part very important.
Common layer every lock signal processing equipment, all be that the layer door switch 1 ' of each floor is connected in series, be connected to control housing by very long cable, be connected to some entrance points of master control board 3 ' again by an AC contactor 2 ' in the control housing, as shown in Figure 1, the drawback of existing layer every lock signal processing equipment maximum is exactly that can only to obtain a layer door lock from this door lock signal be normally or unusual information to mainboard, if but layer door lock is unusual, master control board 3 ' can not judge specifically be which floor the layer door lock unusual, bring very big inconvenience so just for on-the-spot maintenance and commissioning staff, greatly reduce the efficient of elevator maintenance and debugging; Also make apparatus for controlling elevator have certain potential safety hazard and technology leak all the time owing to can not in time correctly reflect the state of each layer every lock effectively.
Summary of the invention
The purpose of this utility model provides the signal processor unit that can obtain each floor layer door lock state information of elevator.
For achieving the above object, the technical solution adopted in the utility model is: elevator door door lock signal processing equipment, this processing equipment comprises each the floor door lock signal branch road that is provided with of being in parallel, be used to receive the master control board of the output information of described each floor door lock signal branch road, the voltage that described each floor door lock signal branch road includes door switch, be electrically connected with described door switch transforms card, transforms the outer controller of calling together that card is electrically connected with described voltage, and each floor described outer called controller together and all be electrically connected on the described master control board according to communications protocol.
Described voltage transitions card adopts and exchanges the transition card that 110V is converted to direct current 24V.
The described outer controller of calling together transmits information by the MODBUS communications protocol to described master control board.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the voltage that each floor door switch is inserted corresponding floor respectively transforms in the card, the output of voltage conversion card inserts the outer of corresponding floor and calls together in the controller, the door lock signal of each floor just can be transferred to master control board according to communications protocol by calling controller outward together like this, master control board contrast communications protocol, receive the floor number of signal data by identification, just can obtain the status information of the layer door switch of each floor, like this can convenient for maintaining and debugging, eliminated potential safety hazard.
Description of drawings
Accompanying drawing 1 is the circuit connection diagram of existing elevator door door lock signal processing equipment;
Accompanying drawing 2 is a circuit connection diagram of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
In Fig. 2, elevator door door lock signal processing equipment, each floor door lock signal branch road 1 that comprising is in parallel is provided with, be used to receive the master control board 2 of the output information of each floor door lock signal branch road 1, the voltage that each floor door lock signal branch road 1 includes door switch 3, be electrically connected with door switch 3 transforms card 4, transforms the card 4 outer controllers 5 of calling together that are electrically connected with voltage, and the outer controller 5 of calling together of each floor all is electrically connected on the master control board 2.Call controller 5 outward together and pass through the MODBUS communications protocol to master control board 2 transmission information.Voltage transitions card 4 adopts and exchanges the transition card that 110V is converted to direct current 24V.
The voltage that each floor door switch 3 is inserted corresponding floor respectively transforms in the card 4, voltage transforms card 4 and is used for the AC110V voltage of door lock signal is changed into DC24V voltage, the output of voltage conversion card 4 inserts the outer of corresponding floor and calls together in the controller 5, like this, the door lock signal of each floor just can be transferred to master control board 2 by the MODBUS communication of calling controller 5 outward together, master control board 2 contrast MODBUS communications protocol, receive the floor number of data by identification, just can obtain the status information of the layer door lock of each floor.This layer every lock signal processing equipment has changed the serial processing mode of existing elevator door door lock feedback signal, has adopted the outer concurrent processing mode of calling the MODBUS communication of controller 5 together of corresponding floor.
In this layer every lock signal processing equipment, by using the mode of parallel transmission, make the door lock signal of each floor independent mutually, make master control board 2 can clearly obtain the status information of the door switch of each floor, potential safety hazard has been eliminated in convenient for maintaining and debugging.
Claims (3)
