[0003] 1. Many lamps and high installation space make it inconvenient to maintain;

[0004] 2. The traditional control mode is loop control, which cannot be changed in later period once the loop is determined; the opening / closing of lamps is controlled according to the loop, which cannot be adjusted scientifically; for example, no matter which track the train stops at, the light is opened / closed according to the loop, which causes a large amount of power waste;

[0005] 3. The traditional installation mode: LED lamps and LED driving modules are installed on the light tower / light bridge and the ceiling of station building, and the damage and replacement of any of LED lamps / LED driving devices need high-altitude operation, and the maintenance is difficult because the operation needs the "window time" designated by railway bureau;

[0006] 4. The sunrise / sunset time in different seasons, especially in winter and summer, is quite different in different regions of China, for example, in Chengdu region, the sunrise time is about AM 6:00 and the sunset time is about PM 8:00 from June to July; the sunrise time is about AM 6:22 min and the sunset time is about PM 7:58 min in August; the sunrise time is about AM 6:40 min and the sunset time is about PM 7:26 min in September; in Shenyang region, the sunrise time is about AM 4:15 min and the sunset time is about PM 7:15 min from June to July; the sunrise time is about AM 4:40 min and the sunset time is about PM 7:04 min in August; the sunrise time is about AM 5:12 min and the sunset time is about PM 6:20 min in September; the sunrise / sunset time in different seasons is quite different in different regions of China, and only manual operation or traditional timing control cannot control the lighting scientifically and accurately, which causes great waste of energy;

[0007] 5. The train schedule is often adjusted due to operation demand or other reasons, which causes the lighting to be unable to be adjusted according to the current demand, resulting in energy waste. INVENTION CONTENT

[0037] Embodiment one, in the embodiment, as shown in Figures 1 to 3 A novel lighting control device based on PLC broadband carrier, comprising a cabinet 1 arranged on the ground, the cabinet is used for controlling the lighting terminal of railway lamp bridge, lighthouse and station building;

[0038] The cabinet 1 is provided with a plurality of PLC drive modules 6, each of which is electrically connected with a corresponding railway lamp bridge, a lighthouse and a lighting terminal of a station building, so that individual control of the lighting terminal is realized; the cabinet 1 is also provided with a central controller 4 and a coupler 5, a plurality of the PLC drive modules 6 are electrically connected with the central controller 4, and the coupler 5 is electrically connected with the PLC drive modules 6 and the central controller 4; each of the PLC drive modules 6 has a unique IP address code, the central controller 4 sends a control instruction to the PLC drive module 6 with the corresponding IP address code, and the PLC drive module 6 controls the lighting terminal according to the instruction. By centrally installing the PLC drive modules in the cabinet, the system is pre-configured with peripheral equipment, and the incoming and outgoing lines of the power line are connected, so that the system can be used. The PLC drive modules do not need to be installed on the lamp bridge, the lighthouse and the ceiling of the station building, so that centralized and unified management is realized, and installation and maintenance are more convenient. The control instruction is a digital signal, the signal is transmitted on the power line through coupling, the PLC drive module 6 extracts the signal from the coupling coil in the PLC drive module 6, and controls the MOS tube through the PWM circuit, so as to control the size of the output current and achieve the required control purpose.

[0039] The central controller 4 has a conversion interface of PLC signal and TCP / IP, and can be operated on a computer, a tablet computer or a mobile phone. Through background software, any loop of the lamp can be combined, turned on / off, and controlled in terms of dimming and color temperature. Figure 8 As shown in the figure, the central controller is built-in with a conversion chip of PLC and TCP / IP communication signals, realizes mutual conversion of PLC communication signals and TCP / IP communication signals, and realizes data interaction of the central controller and control or monitoring software. The model of the central controller is PLH-DPE100.

[0040] In the embodiment, each PLC drive module is built-in with a time register, which records the use time of the module. The central controller 4 reads the use time of each power carrier module 6 and records it in the register of the central controller. These PLC drive modules can be flexibly networked without laying communication lines.
