A method for counting people in a construction elevator

Abstract

The invention relates to a safety monitoring technology for a construction hoist, in particular to a method and a device for determining the passenger capacity of a construction hoist. The output end of a weight sensor is electrically connected with the input end of a signal conditioning module; the output ends of the signal conditioning module and an infrared pair pipe sensor are electrically connected with the input end of a microprocessor; a FLASH memory, a key input module, a sound alarm module and a control output module are respectively and electrically connected with the microprocessor; the microprocessor is further electrically connected with a touch liquid crystal display and a GPRS (general packet radio service) module. Prior to judgment on passenger overloading, the microprocessor acquires passenger in-out information through the weight sensor and the infrared pair pipe sensor, and then calculates the number of real-time passengers in a cage according to a passenger number change algorithm, so that the passenger capacity of the construction hoist can be safely monitored to effectively avoid the passenger overloading.

Description

technical field [0001] The invention relates to a technology for safety monitoring of construction elevators, in particular to a method for counting people of construction elevators. Background technique [0002] The existing safety monitoring of construction elevators can only realize the collection of load signals, and does not have the functions of monitoring and alarming occupants. Although there are methods for image number recognition on the market, due to the environment of the construction elevator cage, especially the light Influence, the correct rate of number identification has been very low, so it is impossible to realize the real and effective safety monitoring of the situation of construction elevators. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, provide a low-cost method for counting people in a construction elevator, realize safety monitoring of the people on the construction eleva...
