Description

Elevator car door landing door detection system

technical field

The utility model relates to the technical field of elevator detection, in particular to a system for detecting the working states of car doors and landing doors of elevators.

Background technique

In the past, the elevator car door and landing door are connected in series through the door lock electric switch, and the feedback signal of the door lock relay is used to judge the status of the car door and landing door. Since the car door and landing door are the moving parts of the elevator, during the use of the elevator, the door runs the most and has the greatest probability of failure. When the car door lock switch or floor door lock switch is abnormal, or when the door lock switch is short-circuited, pasted, or short-circuited, the elevator control system cannot effectively and quickly feedback which floor door or car door the fault point is on. , Troubleshooting takes a long time, if it cannot be maintained in time, there will be potential safety hazards.

Utility model content

The technical problem to be solved by the utility model is to provide a system that can quickly detect the working status of each car door and landing door of the elevator.

The technical solution adopted for solving the above-mentioned technical problems: a detection system of elevator car door landing door, including an induction device for detecting the opening and closing of car door and landing door and a processing control system for monitoring the operation of the elevator, characterized in that: ZigBee intelligent communication modules are respectively embedded on the induction device and the processing control system.

Preferably, the induction device is an electromagnetic induction device.

The beneficial effect brought by adopting the utility model: the utility model realizes the communication between the sensing device and the processing control system by installing a ZigBee intelligent communication module on the induction device of the car door and landing door and the processing control system of the elevator respectively. Wireless communication, point-to-point, one-to-one detection of each elevator car door and landing door, can effectively detect the status of the elevator car door and landing door, and process the control system to compare and analyze the data to judge the car door and landing door Whether there is an abnormality in the state, and it can be accurately analyzed which car door and floor state is abnormal. When the elevator is running or in the door area, when the car door and landing door are opened abnormally, the elevator processing control system receives the information sent by the induction device, and analyzes the abnormal situation through the comparison of the elevator door area information and the elevator operation information. The abnormal state information is stored, and a warning signal can be sent to the ZigBee communication module of the abnormal car door and landing door in time, and the ZigBee communication module of the car door and landing door will send out an audible and visual warning signal to prevent the occurrence of danger.

detailed description

As shown in Figure 1, a kind of elevator car door landing door detection system includes a sensing device 1 for detecting the opening and closing of the car door and landing door and a processing control system 2 for monitoring the operation of the elevator, the sensing device 1 and the processing control system 2 are respectively embedded with ZigBee intelligent communication modules 3 .

The induction device 1 is installed on the car door of the elevator and the doorframe corresponding position of each floor door, and is used for detecting the door opening state and the door closing state of the elevator car door floor door. The floor door ZigBee intelligent communication module 3 transmits the status of each floor door to the outside of the processing and control system 2 of the elevator, and also performs early warning processing. When the floor door sensing device 1 is disconnected, the ZigBee intelligent communication module 3 judges according to the received elevator floor, door area, and operation information. If the elevator car does not stop at the door area at this time, the door is opened. At the moment, the module immediately sends out sound and light danger warnings to prevent danger from happening. Through the self-learning of the elevator door machine, the normal opening and closing time of the elevator car floor door is obtained, and this time is used as the reference time for opening and closing the elevator car floor door. When the elevator is at the leveling position of the current floor, the car door and landing door are opened for loading and unloading passengers, until the elevator door is closed and running, the sensing device 1 on the car door and landing door will be the actual door opening of the elevator at the time interval between receiving these two signals. , Closing time. Compare it with the reference time of opening and closing the door. If it continuously deviates from the reference time, it will prompt the maintenance personnel to analyze the reason. If it is judged to be caused by a fault, it needs to be maintained in time; Humanized elevator peak hour service. The induction device 1 in this embodiment is an electromagnetic induction device.

The ZigBee intelligent communication module 3 is composed of a single-chip microcomputer processing module and a ZigBee communication module. The single-chip processing module is used to process the car door, landing door status signal, elevator floor signal, elevator leveling signal and elevator running signal, exchange information with the ZigBee communication module through serial communication, and control the ZigBee communication module to sleep, wake up, reset, and data Processing, and display communication running status information, fault status information, warning status information. The ZigBee intelligent communication module 3 of the car door and landing door transmits the door state signal to the ZigBee intelligent communication module 3 of the processing control system 2 after receiving the signal of the sensing device 1 . The ZigBee intelligent communication module 3 of the processing control system 2 detects and processes the status of the elevator car door and landing door in real time; if each door is abnormal, the module sends an audible and visual warning signal, and records and displays the abnormal content, Simultaneously transmit information such as elevator floor, door area, operation to car door and landing door ZigBee intelligent communication module 3 in real time.

The ZigBee communication module in this embodiment is completed by the ZigBee TZU06A1 wireless communication module based on the CC2530 chip, and the TZU06A1 module is a 2.4GHz wireless transceiver module conforming to the IEEE802.15.4 protocol and the ZigBee specification.
