Problems solved by technology

In order to achieve this purpose, the current elevator usually judges whether the car light is working normally by detecting the voltage of the car light; however, in actual situations, the voltage detection of the car light When the car light is damaged and opened, the car light still has voltage. Simply by detecting the car light voltage, it will obviously lead to misjudgment

Abstract

The invention discloses an intelligent lift lighting control and detection system comprising a power supply, a control device, a pyroelectric infrared sensor module, an embedded control module and a relay driving module. The embedded control module controls according to signals from the pyroelectric infrared sensor module and controls "on-duty" lamp sets by turns in a timing way. The relay driving module drives the relay of each set of lighting lamps to light up or light out the corresponding LED lighting lamp sets according to the control signals from a lighting control module. Acquisition and comparison of brightness in a compartment and compartment lamp current detection are performed through a light intensity sensor and a photographing unit. The intelligent lift lighting control and detection system can be used for supplementing a conventional compartment lamp voltage detection technology so that leak detection and false detection can be effectively prevented, and the working condition of the compartment lamps can be effectively monitored in real time.

Description

technical field [0001] The invention relates to the field of elevator intelligent control, in particular to an intelligent elevator lighting control and detection system. Background technique [0002] Elevators are tools commonly used in modern buildings. No matter whether there are passengers or not in existing elevators, the lights in the elevator car work always. This not only wastes energy, but also shortens the service life of the lighting lamp. [0003] The car is a space for carrying and transporting people and materials. Since it is closed during operation, it needs to provide appropriate lighting for the passengers. Therefore, it is necessary to install lighting fixtures in the car, and it is necessary to ensure that the lighting fixtures are in normal working condition. In order to achieve this purpose, the current elevator usually judges whether the car light is working normally by detecting the voltage of the car light; however, in actual situations, the voltag...
