Problems solved by technology

Although it is possible to add conversion equipment and bus relays to solve the application of multiple communication nodes in long-distance tunnels, it will face a huge workload for on-site installation and commissioning, and it will also increase the engineering cost and the complexity of the control platform

Embodiment Construction

[0029] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in conjunction with the embodiments, and the content involved in the embodiments is not a limitation on the content of the present invention.

[0030] Such as figure 1 As shown, the tunnel light based on visible light communication technology and its communication control method of the present invention uses two different frequency modulated signals of visible light communication and infrared communication to form a closed loop communication loop, and the main controller uniformly manages the work of each node status.

[0031] The node includes: a slave controller and a lamp body; the lamp body only includes an ED light source module, a frame and a fixed bracket; the slave controller includes: an LED drive power supply, a processing unit, a visible light transmitting module, an LED lamp cup, and a visible light receiving module , Infrared transmitter tube, in...

Abstract

The invention discloses a tunnel lamp based on the visible light communication technology and a communication control method thereof, and relates to the field of LED lighting. A closed-loop communication circuit is formed through the two close-range high-speed wireless communication technologies of visible light communication and infrared communication. The problem that the number of nodes of an RS-485 bus in a tunnel lighting control mode is excessively small for the reasons of drive capability limitation, cable losses and the like can be solved, and the work of manually presetting address codes is further omitted. The communication control method is easy and convenient to operate and low in cost. Data can be uploaded to a remote management platform through a master controller, and the lighting effect can be adjusted automatically according to the brightness outside a tunnel.

Description

Technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to an LED tunnel lamp and its lighting communication control. Background technique [0002] With the wide application of LED tunnel lights, the demand for remote control and communication control is becoming more and more obvious. Tunnel lighting fixtures need to work for 24 hours in the tunnel. Because they are in a semi-enclosed outdoor space, the environment is harsh, and because they are far from the city, energy-saving control is more important. At present, GPRS can be used to solve the remote control problem, and the local automatic control mostly uses the RS-485 bus. However, due to the parallel connection method between the master controller and the slave controller on the RS-485 bus, the long-distance drive capacity is limited, cable loss and other reasons, resulting in not too many communication nodes, short communication distance, and some The length of the tu...
