[0030] Unless otherwise defined, the technical or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which the utility model belongs. The words "first", "second" and similar words used in the patent application specification and claims of the utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "a" do not indicate a quantity limitation, but indicate the existence of at least one.

[0031] refer to Figures 1 to 3 The present embodiment provides a tunnel power outage warning sign, which is arranged outside the guardrail on the right side of the road away from the tunnel entrance. The distance between the tunnel power outage warning sign and the tunnel entrance is 100 meters to 200 meters, preferably 150 meters.

[0032] The tunnel power outage warning sign includes a control host, a lifting device 10 and a warning sign 20. The lifting device 10 is installed on the ground, and the warning sign 20 is installed on the top of the lifting device 10. The control host is connected to the lifting device 10 to control the warning sign to be in a standby state or a working state.

[0033] Among them, when the tunnel power outage warning sign is in standby mode, the height of the warning sign 20 is lower than the height of the guardrail, and the warning sign 20 is hidden outside the guardrail, which does not affect normal driving judgment. When the tunnel power outage warning sign is in working mode, the height of the warning sign 20 is higher than the height of the guardrail, which is convenient for drivers entering the tunnel to see.

[0034] The lifting device 10 includes a base 11, a fixing rod 12, a lifting rod 13, a motor and a mounting plate 14. Figure 4 As shown. The base 11 is installed on the ground, the fixed rod 12 is installed on the side of the base 11 away from the ground, the lifting rod 13 is sleeved on the end of the fixed rod 12 away from the base 11, a motor is installed on one end of the lifting rod 13, the output shaft of the motor is transmission-connected with the lifting rod 13, and the mounting plate 14 is installed on the end of the lifting rod 13 away from the fixed rod 12. Specifically, the base 11 and the mounting plate 14 are both rectangular fixed plate structures, a plurality of threaded holes are arranged on the fixed plate, and the base 11 is fixedly mounted on the ground by screws. Preferably, the lifting stroke of the lifting device 10 is 10 meters.

[0035] The warning sign 20 is fixed to the mounting plate 14 by screws. The warning sign 20 is a rectangular frame structure, including an upper frame and a lower frame arranged relatively, the upper frame is the side close to the ground, and the lower frame is the side away from the ground. Preferably, the height of the warning sign 20 is lower than the height of the guardrail, which means that the height of the lower frame of the warning sign 20 is lower than the height of the guardrail, and preferably the height of the lower frame of the warning sign 20 is 1 meter; the height of the warning sign 20 is higher than the height of the guardrail, which means that the height of the upper frame of the warning sign 20 is higher than the height of the guardrail. The prompt words on the surface of the warning sign 20 are set as needed.

[0036] The tunnel power outage warning sign also includes a control switch, and the control switch signal is connected to the control host. The tunnel power outage warning sign is powered by a 24V DC power supply, connected to the tunnel UPS uninterruptible power supply system, and only the lifting and lowering process of the lifting rod 13 consumes electricity.

[0037] The tunnel power outage warning sign also includes a flashing warning light 30, which is fixed to the mounting plate 14 by screws. When the tunnel power outage occurs, the flashing warning light 30 flashes to attract the driver's attention, and at the same time, a voice broadcast is performed to prompt the tunnel situation ahead. The voice broadcast decibel is less than or equal to 120 decibels, the decibel size is adjustable, and the voice broadcast content can be modified.

[0038] The tunnel power outage warning sign also includes a solar panel 40, which is fixed to the mounting plate 14 by screws, and the solar panel 40 is connected to the flashing warning light 30. The solar panel 40 can convert and store solar energy on sunny days into electrical energy, ensuring that the tunnel power outage warning sign can continue to work for more than 24 hours in the absence of light.

[0039] The main material of the tunnel power outage warning sign is aluminum plate, which is suitable for various adverse climates and adverse environments. In particular, the surface of the warning sign 20 is made of reflective material, which plays a strong warning role in night driving. It is made of acid and alkali resistant, corrosion resistant, and does not fade outdoors in wind and rain. The sound and light alarm device adopts IP65 protection grade design.

[0040] This embodiment also provides a tunnel power outage warning system including the above-mentioned tunnel power outage warning sign, and its circuit diagram is as follows Figure 5 shown.

[0041] The tunnel power outage warning system also includes a guide light group, which is set at the entrance section of the tunnel. When the tunnel power outage occurs, the guide light group flashes to guide the vehicle to travel, and prevents the vehicle from colliding with the road edge when the vehicle does not turn on the headlights. The guide light group is powered by a 24V DC power supply and connected to the tunnel UPS uninterruptible power supply system. The power of each lamp is only 0.08W, with low power consumption. With the synchronous flashing controller, a synchronous flashing prompt effect is achieved.

[0042] The tunnel power outage warning system also includes a communication module, and the communication module signal is connected to the control host. When the tunnel power outage occurs, an alarm message is actively sent to the maintenance personnel's mobile phone at the first time, so that the maintenance personnel can understand the on-site situation as quickly as possible; when the tunnel power supply is restored, the power supply restoration information is sent to the maintenance personnel's mobile phone. The communication module uses the Internet of Things technology to push monitoring information in real time and notify the maintenance personnel through multiple methods such as phone calls, text messages, and WeChat.

[0043] The tunnel power outage warning system also includes a power monitoring module, which is connected to the tunnel power system and the control host. The power monitoring module monitors the tunnel power system around the clock and transmits the monitoring data to the control host. The control host makes judgments based on the monitoring data and responds accordingly.

[0044] Specifically, the operation steps of the tunnel power outage warning system are as follows:

[0045] In the first step, the power monitoring module monitors the operation of the tunnel power system and transmits the monitoring data to the control host;

[0046] In the second step, the control host makes judgments based on the monitoring data and responds accordingly.

[0047] When it is determined that there is a power outage in the tunnel, the tunnel power outage warning sign switches from the standby state to the working state, and the warning sign 20 is raised to a height higher than the height of the guardrail; the flashing warning light 30 flashes to attract the driver's attention, and a voice broadcast is made to remind the driver of the tunnel situation ahead; the guide light group flashes; and the power outage alarm message is sent to the maintenance personnel's mobile phone.

[0048] When it is determined that the power supply to the tunnel is restored, the tunnel power outage warning sign switches from the working state to the standby state, the warning sign 20 descends to a height lower than the height of the guardrail; the flashing alarm light 30 turns off flashing and voice broadcasting; the guide light group turns off flashing; and the power restoration message is sent to the maintenance personnel's mobile phone.

[0049] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
