Elevator call communication system

Abstract

The present invention relates to an elevator call communication system, comprising an elevator control device, a luminous body emitting visible light, a portable terminal with a visible light emitting and receiving module, a receiver for receiving visible light signals sent by the portable terminal, an elevator control device, and a luminous body 1. An optical communication controller electrically connected to the portable terminal and the receiver. The optical communication controller has an optical communication control circuit and a lighting circuit for controlling the operation of the luminous body. The luminous body and the receiver are both arranged in the elevator car. The optical communication controller of the present invention realizes receiving, identifying, separating and transmitting the information sent by the passenger's portable terminal through the luminous body and the receiver, so as to realize the delivery of elevator running instructions, personal identification of passengers, information interaction of the building information system and the Internet Connect, providing passengers with high-speed, energy-saving, environmentally friendly and convenient communications.

Description

technical field [0001] The invention relates to the technical field of elevator calling, in particular to an elevator calling communication system. Background technique [0002] Elevator, as a means of vertical transportation in a modern city, is a device that every modern person cannot leave every day. With the development of elevator technology, passengers can use mobile communication terminals to realize elevator calling. At present, in order to realize the interconnection between people's mobile communication terminals and elevators, radio frequency technology is generally used. The elevator car itself is a relatively airtight metal cage. According to the principle of Faraday cage, the car itself is a shield for radio frequency signals. Therefore, if you want to realize the radio frequency communication inside and outside the car, you must use strong enough communication power and It can only be realized by transmitting the base station at a short distance, but this wil...

Problems solved by technology

The elevator car itself is a relatively airtight metal cage. According to the principle of Faraday cage, the car itself is a shield for radio frequency signals. Therefore, if you want to realize the radio frequency communication inside and outside the car, you must use strong enough communication power and It can only be realized by transmitting the base station at a short distance, but this will lead to the expansion of radio frequency pollution in the living environment and the ineffective loss of power supply.
