Cabin bionic illumination control system and method in closed environment based on CAN communication

Abstract

The invention discloses a cabin bionic lighting control system and a cabin bionic lighting control method in a closed environment based on CAN communication. The system comprises an illumination control device and a plurality of bionic illumination lamps, wherein the bionic illumination lamps are respectively connected with the illumination control device. The method comprises the steps that a user sends an instruction to the main control board through the key board; the main control board processes the instructions and displays different interfaces for the user through the display screen according to different instructions; meanwhile, according to a user instruction, the ARM core board controls the bionic lighting lamp to adjust the brightness and the color temperature through the CAN module, the current working state of the bionic lighting lamp is inquired, and the bionic lighting lamp adopts an LED light source with cold and hot color temperatures. By the adoption of the method, remote intelligent control over the lamp is achieved through CAN communication; thus, it is ensured that a user can accurately and rapidly conduct dimming on the lamp through the cabin bionic lighting control system in a complex and changeable closed environment.

Description

technical field [0001] The invention belongs to the technical field of controllers, in particular to a cabin bionic lighting control system and method in a closed environment based on CAN communication. Background technique [0002] At present, research on bionic lighting mainly focuses on building types such as hospitals and classrooms. Although the bionic products can be controlled by smart phones, tablet computers, computers and other terminals, they are mostly controlled by WIFI, 4G, Zigbee and other communication methods. This communication method is mostly used in open indoors, and the signal strength The requirements are high, and the load capacity is low, the communication distance is short, and the stability is poor. It cannot be used in complex communication environments, and it cannot be used in closed environments with harsh communication environments such as cabins and basements. [0003] Lighting is also closely related to the rhythm and physiological health o...

AI Technical Summary

Problems solved by technology

Due to the unreasonable configuration of lamps in the closed environment, there are unreasonable distribution of brightness in the cabin and prominent glare, which causes the problem of decreased vision of personnel

Some environments have too high illumination at the same time, which is likely to cause waste of energy consumption and visual discomfort.

[0004] The current bionic lighting fixtures on the market do not have the function of intelligent dimming and color adjustment according to day and night changes, and the color temperature adjustment range is small, so they cannot simulate the color temperature and brightness changes of the sun from sunrise to sunset, and cannot be used in closed environments Improving the comfort of personnel to the light environment

Moreover, on the market, the dimming method of changing the output PWM duty cycle is often used to adjust the brightness and color temperature. This method is easy to be captured by the camera and affects daily work, and the PWM signal is a high-frequency signal, which is prone to electromagnetic interference.
