[0033] II level, medium risk: the risk level is conditionally acceptable, and the project needs to further implement prevention measures to improve safety. According to the actual situation of the project, certain measures are taken, such as strengthening the treatment of adverse geology, using good filling materials, improving the safety of the structure, and reducing the possibility of roadside risk occurrence.
[0034] III level, high risk: the risk level is conditionally acceptable, and it is necessary to implement response measures to reduce safety risks and prepare emergency plans. Measures must be taken, including strengthening the treatment of adverse geology, using good filling materials, improving the safety of the structure, and reducing the possibility of roadside risk occurrence.
[0035] IV level, extremely high risk: the risk level is unacceptable, and effective response measures must be taken to reduce the risk level to the level of III and below.
[0036] In some specific embodiments, based on the risk level of the identified potential road disaster risk zone, the preset risk level described in this application is set to Level III or above, and the road depression warning device of this application can be installed in the section with a risk level of Level III or above.
[0037] The following is in conjunction with the appendix to this instruction manual. Figures 1 to 2 The preferred embodiments of this disclosure will be further described in detail.
[0038] According to some embodiments, the first prompting device and the second prompting device have the same structure. The first prompting device includes a signal detection circuit, a driving circuit and a prompting circuit. The input terminal of the signal detection circuit is connected to the first terminal 101 and the second terminal 102 of the first detection line 1. The output terminal of the signal detection circuit is connected to the driving circuit. The output terminal of the driving circuit is connected to the prompting circuit.
[0039] When the signal detection circuit detects a road depression, the drive circuit activates the warning circuit, which in turn activates the load connected to the warning circuit to issue a warning about an abnormal road ahead.
[0040] According to some embodiments, such as Figure 2 As shown, the signal detection circuit includes a first transistor Q1, a first resistor R1, a second resistor R2, a third resistor R3, and a fourth resistor R4.

[0041] The working principle of the above embodiment is as follows: When the road is normal, the base of the first transistor Q1 receives a low-level signal through the second resistor R2 and the third resistor R3, the first transistor Q1 is cut off, and neither the driving circuit nor the prompting circuit works. When a road depression occurs, the first detection line 1 is disconnected, the second resistor R3 and the third resistor R3 are open-circuited, the base of the first transistor Q1 is pulled up by the first resistor R1, the first transistor Q1 conducts and outputs power, the driving circuit is powered on, and the prompting circuit works to issue a warning of road abnormality ahead.
[0042] In some embodiments, such as Figure 2 As shown, based on the above circuit, the signal detection circuit also includes a fifth resistor R5. One end of the fifth resistor R5 is connected to the base of the first transistor Q1, and the other end of the fifth resistor R5 is grounded.
[0043] According to some embodiments, such as Figure 2As shown, the drive circuit includes the second transistor Q2, the first relay K1, the sixth resistor R6 and the seventh resistor R7, the base of the second transistor Q2 is connected to the other end of the fourth resistor R4 and one end of the sixth resistor R6, the other end of the sixth resistor R6 is grounded, the collector of the second transistor Q2 is connected to one end of the coil of the first relay K1, the emitter of the second transistor Q2 is grounded, the other end of the coil of the first relay K1 is connected to the power supply through the seventh resistor R7, one end of the contactor of the first relay K1 is connected to the power supply, and the other end of the contactor of the first relay K1 is connected to the prompt circuit.
[0044] The working principle of the above embodiment is that when the first transistor Q1 is off, the base of the second transistor Q2 receives a low-level signal through the sixth resistor R6, the second transistor Q2 is off, the coil of the first relay K1 is not powered, the contactor of the first relay K1 is open, and neither the drive circuit nor the prompt circuit works. When the first transistor Q1 is turned on to output the power supply, the coil of the first relay K1 is powered, the contactor of the first relay K1 is attracted, the prompt circuit receives the power supply, and the prompt circuit works to issue a front road abnormality prompt.
[0045] According to some embodiments, as Figure 2 As shown, the prompt circuit includes the eighth resistor R8 and the flashing light D1, the positive electrode of the flashing light D1 is connected to the other end of the contactor of the first relay K1 through the eighth resistor R8, and the negative electrode of the flashing light D1 is grounded.
[0046] Further, as Figure 2 As shown, the prompt circuit further includes the ninth resistor R9 and the alarm bell LS1, the positive electrode of the alarm bell LS1 is connected to the other end of the contactor of the first relay K1 through the ninth resistor R9, and the negative electrode of the alarm bell LS1 is grounded.

[0048] The working principle of the above embodiment is that when the contactor of the first relay K1 is open, the flashing light D1, the alarm bell LS1 and the loudspeaker LS2 are not powered and do not work. When the contactor of the first relay K1 is attracted, the flashing light D1, the alarm bell LS1 and the loudspeaker LS2 are powered and work.
[0049] The flashing light D1 is used to issue a warning (light warning) to an oncoming vehicle in a burst flash mode when the detection line buried in the roadbed (or fixed to the bridge potential disaster risk area beam body) is broken in the event of a serious disaster.
[0050] The alarm bell LS1 is used to send an alarm (sound alarm) to the oncoming vehicle in the form of a warning when the detection line buried in the potential disaster risk area of the road (or fixed on the beam body of the potential disaster risk area of the bridge) is broken in the event of a serious disaster.
[0051] The loudspeaker LS2 is used to send an alarm (voice alarm) to the oncoming vehicle in the form of a voice shout or instruction when the detection line buried in the potential disaster risk area of the road (or fixed on the beam body of the potential disaster risk area of the bridge) is broken in the event of a serious disaster.
[0052] According to some embodiments, as shown in Figure 2 The second relay K2 is provided between the collector of the first triode Q1 and the power supply, the first contactor K21 of the second relay K2 is provided between the second resistor R2 and the first end 101 of the first detection line 1, the second contactor K22 of the second relay K2 is provided between the second end 102 of the first detection line 1 and the third resistor R3, and the first contactor K21 and the second contactor K22 of the second relay K2 are normally closed switches.
[0053] The contactors of the second relay K2 are in a normally closed state.
[0054] When the road is concave, the first detection line 1 is disconnected, the base of the first triode Q1 is pulled up by the first resistor R1, the first triode Q1 is turned on, the coil end of the second relay K2 is powered, and the contactors of the second relay K2 are disconnected.
[0055] Further, as shown in Figure 2 The third triode Q3 is used for resetting, the collector of the third triode Q3 is connected to the power supply, and the emitter of the third triode Q3 is connected to the collector of the first triode Q1 through the coil end of the second relay K2.
[0056] The working principle of the above embodiment is that the base of the third triode Q3 always inputs a high-level signal 200, so that the third triode Q3 is always in a conducting state, when the road is concave and the repair is completed, a low-level signal 200 is input to the base of the third triode Q3, the coil end of the second relay K2 loses power, and the contactors of the second relay K2 return to the normally closed state, completing the reset.
[0057] According to some embodiments, the prompt device further comprises a power indicator D2 and an eleventh resistor R11, the positive electrode of the power indicator D2 is connected to the power supply through the eleventh resistor R11, and the negative electrode of the power indicator D2 is grounded.
