Elevator floor data collecting device and elevator floor operation monitoring and controlling system and method

Abstract

The invention provides an elevator floor data collecting device. The device comprises a data processing module, an RFID read-write module, an air pressure sensor, and an RFID label; elevator floor information is stored in the RFID label, the air pressure sensor is used for sensing pressure of the current position of an elevator cage and producing a corresponding current pressure signal, the data processing module sends a read-write control signal to the RFID read-write module at regular time and receives the elevator floor information obtained from the RFID label by responding of the read-write control signal by the RFID read-write module, the data processing module is further used for collecting the current pressure signal produced by the air pressure sensor at regular time and producing a corresponding current pressure value according to the collected current pressure signal, and the data processing module is further used for calculating a current height value of a floor where the elevator cage locates according to the elevator floor information, the current pressure value, a pre-stored floor base pressure value and a pre-stored unit pressure height value. The invention further provides an elevator floor operation monitoring and controlling system and method.

Description

technical field [0001] The invention relates to the technical field of elevator safety monitoring, in particular to an elevator floor data acquisition device, an elevator floor operation monitoring system and a method. Background technique [0002] In order to protect the safety of the elevator operation, it is necessary to detect the car door and the hall doors of each landing. Only when the elevator car door and the hall doors of all landings are closed, the elevator can start running. Elevator safety regulations in various countries have There are strict regulations on this. With the continuous development of my country's market economy and the continuous expansion of city scale, there are more and more high-rise residential buildings, hotels, and office buildings, and the number of elevators installed is also increasing rapidly. These elevators bring convenience to people entering and leaving high-rise buildings. The level of potential safety hazards, and some even bring...

Problems solved by technology

[0006] The above-mentioned application number is 201110035275.5, and the Chinese invention patent application titled "Intelligent alarm system for abnormal opening of elevator hall door and its safety detection method" can be solved. However, the above-mentioned application number is 201110035275.5, and the Chinese invention patent application titled "Intelligent Alarm System for Abnormal Opening of Elevator Hall Door and Its Safety Detection Method" still has the following problems: If a large number of wireless transmitting devices such as WIFI base stations and 3G base stations are installed in the elevator shaft, the electromagnetic environment of the elevator shaft will become more and more complicated. The addition of the above-mentioned third-party acquisition sensors will be subject to electromagnetic interference, resulting in errors in the collected data and data errors. The post-acquisition alarm device will cause false alarms of elevator failures, which will affect the user experience; in addition, when the elevator fails and the car stays in the elevator shaft, the system can only provide the floor information of the car. However, the specific position of the car on the floor cannot be provided accurately, which makes it difficult to carry out the work of rescuing the trapped people.
