Position monitoring method and system

Abstract

The invention provides a position monitoring method and system. When an accident occurs, a movable device stops at a certain floor and controls a light emitter located on the bottom of the movable device to emit a visible light signal, and a single-photon detector located on the bottom of a preset rail of the movable device detects the visible light signal to obtain the current number of photons; due to the fact that the movable device stops at different heights, the single-photon detector obtains different numbers of photons, the current number of photons is converted into an electric signal with a corresponding amplitude value, the electrical signal is processed according to a preset rule, so that the current position information of the movable device is obtained and output to enable working staff to learn the current position of the movable device quickly and accurately, and then working efficiency is improved greatly; furthermore, information transmission is achieved by means of the visible light signal, power is supplied without traditional power lines, and the influence of accidents on the work of a traditional monitoring system is avoided.

Description

technical field [0001] The present invention mainly relates to the field of safety management, and more specifically relates to a position monitoring method and system. Background technique [0002] In practical applications, in order to ensure the safety of elevator operation in high-rise buildings, it is usually necessary to install a car terminal in the elevator car, collect the running data of the car through the car terminal in real time, and send it to the machine room terminal, so that the machine room terminal The status data and car running data are sent to the remote monitoring center, which analyzes the above data to obtain the running status data and maintenance data of the elevator, so as to realize the monitoring and daily maintenance of the elevator. [0003] However, the applicant found that, since the car terminal and the machine room terminal, as well as the machine room terminal and the remote monitoring center are connected through a communication network...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a method and system for position monitoring, which solves the problem that the existing elevator monitoring system cannot work normally in case of an emergency, thus causing the staff to be unable to know the specific position of the car, which is necessary for elevator maintenance work. causing a lot of inconvenience
