Embodiment 1
[0027] This embodiment mainly introduces the basic composition of a self-powered tunnel lighting system.
[0028] Such as figure 1 Shown is a tunnel lighting control system based on self-powered carrier wireless dual-mode communication, including a lamp 1, a terminal controller 2, a centralized controller 3, a host computer 4, and a water flow pipe TEG module 5; among them, the lamp and the terminal There are multiple controllers, the lamps are connected to the terminal controller, the terminal controller is connected to the centralized controller, and the centralized controller is connected to the host computer; a terminal controller is installed on the lamp holder of each lighting lamp to be responsible for the switch control of the lamps , and feed back the operating parameters of the lamps to the centralized controller at the same time; the centralized controller collects real-time data of traffic flow and brightness values inside and outside the tunnel, and completes th...
Embodiment 2
[0030] This embodiment is carried out on the basis of the first embodiment above, and mainly introduces the schematic diagram of the side section of the tunnel where the water flow tube TEG module is embedded as a power supply system, and the principle and technical solution of the self-power supply of the water flow tube TEG module.
[0031] The embedding method of the water flow pipe TEG module inside the tunnel is as follows: figure 2 As shown, 11 represents a section of tunnel, the subgrade 13 is buried directly below the tunnel pavement 12, the heat collecting pipe 14 is buried under the subgrade 13, 15 is the underground water pipeline under the subgrade, and 5 is the water flow pipe TEG module embedded between the heat collecting pipe 14 and the groundwater Between pipes 15.
[0032] Such as image 3 Shown is the internal structure of the water flow tube TEG module 5, which is obtained by connecting many pairs of PN junctions 23 in series, and uses the Seebeck effect ...
Embodiment 3
[0038] This embodiment is carried out on the basis of the foregoing embodiment 1 or 2, and mainly introduces the structure of the lighting control system and their technical solutions.
[0039] Such as Figure 4 It is a schematic diagram of the structural connection of the lighting control system. The water flow pipe TEG module 5 provides the electric energy required by the entire system; the vehicle detector 37 and the light intensity detector 38 of the data acquisition module of the centralized controller send the collected data to the STM32 of the control module In the chip AT89C51 processor 34 of model, then information is transmitted in the upper computer 4 by carrier wireless transceiver circuit 32 and coupling circuit 31, in this process, use LME2981 chip 33 to realize dual-mode communication; Upper computer 4 can send to each relay The control circuit 36 sends instructions to control the switch of the lamp 1. The upper computer also transmits information through the ...
