Elevator monitoring apparatus employing ZigBee wireless network technique

Abstract

The invention relates to an elevator monitoring apparatus which employs the ZigBee wireless network technology, and comprises a computer of an elevator monitoring center, at least one elevator main controller, Zigbee interface modules of an elevator monitoring controller and Zigbee interface modules of the elevator monitoring center, wherein the number of the Zigbee interface modules of the elevator monitoring controller and the elevator monitoring center are same with that of the elevator main controller. The signal of the elevator main controller is transmitted to the Zigbee interface modules of the elevator controller, and the Zigbee interface modules of the elevator controller transmits the signal to the computer of the elevator monitoring center through the Zigbee interface modules of the elevator controller. The elevator monitoring apparatus has the advantages that the elevator monitoring apparatus can realize the elevator monitoring of the wireless network without monthly fee, thereby saving cost, facilitating installation, and reducing non-recurring costs.

Description

technical field [0001] The invention relates to an elevator monitoring system, in particular to an elevator community monitoring system. Background technique [0002] With the rapid development of my country's social economy, the real estate industry has shown a great development situation. As a means of transportation in buildings, elevators have been more widely used, and the installation volume of elevators has also increased significantly. Therefore, its safety and reliability have also become more and more important. More and more important, and the monitoring system of the elevator is an important means to ensure the safety and reliability of the elevator. [0003] The existing elevator monitoring systems are divided into the following types. One is the community monitoring system based on RS485 bus or CAN bus. A group of elevator controllers are connected to the computer in the monitoring center through communication cables. The advantage is that no additional expendit...

Problems solved by technology

[0003] The existing elevator monitoring systems are divided into the following types. One is the community monitoring system based on RS485 bus or CAN bus. A group of elevator controllers are connected to the computer in the monitoring center through communication cables. The advantage is that no additional expenditure is required. The disadvantage is The reason is that the wiring is inconvenient and the anti-interference is poor; one is network monitoring based on telephone lines or network cables. It can monitor the status of the elevator, the advantage is that the communication distance is not limited, the disadvantage is that it needs to be wired to the machine room, the wiring is inconvenient, and the telephone line or network cable needs a fixed monthly fee; there is also a wireless monitoring system based on GPRS / CDMA technology , through a GPRS / CDMA data acquisition node installed in the computer room, the elevator controller is connected to the network of the mobile operator, and then connected to the Internet through the network of the mobile operator. The advantage is that the installation and maintenance are convenient, and the disadvantage is that the equipment cost is high. Pay the monthly rent to the mobile operator every month
