[0030] Figure 2 This diagram shows the circuit schematic of a warning light system applicable to port defense systems according to this invention. The lower right dashed box contains the display control board, and the rightmost part is the display board. Figure 2 The diagram shows three exemplary display panels; the photovoltaic panel is a local independent unit; the remaining blocks contain the main control board and various sub-functional modules. Figure 2 As shown, the main control board 6 includes a microcontroller unit (MCU).

[0031] The first DC-DC module has its input terminal connected to a wired power supply cable and its output terminal connected to the first input terminal of the first selector switch. The photovoltaic panel 2 is connected to the second input terminal of the first selector switch. The output terminal of the first selector switch is connected to the switch array of the display control board 4. The first DC-DC module can be installed on the main control board to achieve long-distance DC power conversion, thereby meeting the main energy consumption power needs of the display panel. Therefore, wired power supply or photovoltaic power supply can be selected according to the power supply situation, making the power supply method more flexible.
[0032] Preferably, the junction box 3 is further provided with a lithium battery and the main control board 6 also includes a charging switch connected to the microcontroller unit MCU (i.e., Figure 2 s1), control switch (i.e. Figure 2 s2) and the second selection switch (i.e. Figure 2 (sw2 in the diagram).

The output terminal of the bypass is connected to the second input terminal of the second selection switch. The output terminal of the second selection switch is connected to the switch array of the display control board 4. Therefore, this utility model uses lithium battery energy storage to meet emergency power supply needs, improves power supply reliability, and can adapt to scenarios such as power system failure or power outage during maintenance.
[0033] More preferably, the main control board 6 further includes a second DC-DC module (i.e. Figure 2 (DC-DC2 in the diagram).

[0035] Preferably, the wired network adopts an industrial bus 485 protocol, and uses a daisy chain networking mode to improve the communication success rate.The wireless network adopts a high-speed serial port of LoRa spread spectrum communication, and uses a multi-channel, high-power antenna to transmit and high-sensitivity reception to ensure sufficient gain and good anti-interference performance at a distance of several kilometers.

[0038] The charging of the lithium battery can be realized by the following mode: detecting whether the output voltage of the lithium battery is insufficient, if it is insufficient, the lithium battery is charged. At the same time, in order to ensure the safety of charging and the service life of the lithium battery, a temperature sensor can be used to detect the temperature of the lithium battery during charging, and the change of charging current is detected. When the battery temperature or charging current rapidly rises and exceeds the safety value, the charging switch s1 is automatically disconnected, the abnormal processing program is entered, and the alarm or prompt information is generated.
[0039] The switching of the wired network and the wireless network can be realized by the following mode: first judging whether the power supply of the 485 interface is normal, and then judging whether the communication link and data are normal, which can shorten the emergency response adjustment time, if all are normal, the wired network mode is used to ensure the communication reliability; if any of the above steps is abnormal, the wireless network is switched to try communication, if there is a problem, the abnormal processing program is entered, including wireless communication adaptive adjustment, if it is still unsuccessful, the alarm is reported.
[0040] In the utility model, the main control board can be used to realize the function selection or switching of the power supply mode and the communication mode by the electronic switch elements.
