Fixed member counting system for to-be-detected area based on laser correlation detection technology

Abstract

The invention discloses a fixed member counting system for a to-be-detected area based on a laser correlation detection technology. The fixed member counting system comprises a first pair of laser correlation detectors, a second pair of laser correlation detectors, a third beam and a fourth beam, wherein the first beam and the second beam are parallel to each other; an address module, used for encoding the address of each light beam and sending the address code corresponding to the blocked light beam to the alarm host; and an alarm host, used for determining the sequence of the address codes of the blocked light beams according to the address codes corresponding to the blocked light beams so as to determine the personnel access information of the to-be-detected area. The problems that in the prior art, environment interference is likely to happen, shielding cannot be achieved, the counting precision is low, and the intelligent degree is low are solved.

Description

technical field [0001] The invention belongs to the technical field of safety production management, and in particular relates to an occupancy counting system of an area to be measured based on laser beam-to-beam detection technology. Background technique [0002] In order to reduce the safety risk of work in the hazardous area, the number of workers in the hazardous area must be limited. At present, most dangerous areas still use the method of manually turning over the counting boards for personnel counting. This way of counting people has the following problems: 1) Multi-channel openings cannot be taken into account, which may easily cause mistakes in counting people; 2) Alarm prompts for lack of personnel and excess; 3) Low level of automation, operators may turn over less, more, or mistakenly turn over the counting cards 4) The degree of intelligence is low, and the entrances and exits of most dangerous areas still have some characteristics of open scenes, for example, ...
