Elevator external calling display system

Abstract

The invention provides an elevator external calling display system. The elevator external calling display system comprises a processing unit; the processing unit is connected with a communication unit, a human body detection unit and a display unit, and the processing unit, the communication unit, the human body detection unit and the display unit are all collectively powered by a power supply module. According to the system, energy conservation and consumption reduction can be effectively achieved, energy consumption and component work when no one stays in an elevator waiting hall or enters the elevator waiting hall are avoided, and the service life of electronic components is effectively prolonged.

Description

technical field [0001] The invention relates to an elevator hall call display system. Background technique [0002] At present, the external display panel of each floor of the elevator includes a liquid crystal display window, a floor display, a running direction display, and an up and down call button. According to statistics, the average utilization rate of display panels outside the stations of elevators in my country is very low. Idle most of the time. Even when no one is in use, the liquid crystal display window, floor display, and running direction of the display panel outside the station of each floor of the elevator are always displayed. cause huge energy consumption. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an elevator hall call display system, which can effectively realize energy saving and consumption reduction, and avoid energy consumption and component work when there is no one in the ...
