Description

Technical Field

[0002] Debris flow is a common geological disaster in the mountainous areas of southwest China. It is characterized by sudden occurrence, short duration, fierce force and strong destructive power, often destroying residential areas and infrastructure located at the mouth of the debris flow. Moreover, after the debris flow breaks out, it may still break out again, thus affecting the emergency rescue work after the debris flow disaster.

[0003] In the relevant technology, there are many methods for warning of debris flow, such as manual monitoring, drone image monitoring and vibration signal monitoring. Emergency rescue is a time-sensitive and dangerous task. However, manual monitoring and warning of debris flow has the disadvantages of high risk, time-consuming and labor-intensive. The use of drone images to monitor and warn of debris flow is greatly affected by atmospheric visibility and drone endurance, and it is difficult to support long-term rescue under poor weather conditions. The vibration signal monitoring method has the advantage of high accuracy, but the post-processing and analysis time of the monitoring data is long, which is not conducive to the smooth implementation of emergency rescue work.

[0043] In the description of the present invention, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0044] According to a first aspect of the present invention, a real-time monitoring device 100 for post-debris flow disaster emergency rescue is disclosed. Figures 1 to 3 , including a piezoelectric ceramic layer 120, a monitoring module 110, an insulating layer 160 and an electrical connector 130, wherein the monitoring module 110 includes a signal transmitter 111, the signal transmitter 111 is arranged on the inner side of the piezoelectric ceramic layer 120, and the signal transmitter 111 is used to transmit a signal to an external alarm device 200, so that the alarm device 200 can remind emergency rescue personnel to avoid mudslides; the insulating layer 160 is arranged on the inner side of the piezoelectric ceramic layer 120 and wrapped on the outer side of the monitoring module 110; the electrical connector 130 is penetrated by the insulating layer 160 and is arranged between the piezoelectric ceramic layer 120 and the signal transmitter 111, wherein the piezoelectric ceramic layer 120 provides an electric charge to the signal transmitter 111 through the electrical connector 130 when being squeezed, so that the signal transmitter 111 can transmit a signal to the external alarm device 200.

[0045] Specifically, after the real-time monitoring device 100 is assembled, the drone 310 places the real-time monitoring device 100 in the debris flow. When the debris flow breaks out again, the piezoelectric ceramic layer 120 generates an electric charge under the impact of the debris flow, and the generated electric charge is transmitted to the signal transmitter 111 through the electrical connector 130, and the signal transmitter 111 transmits a signal to the outside. The external alarm device 200 receives the signal emitted by the signal transmitter 111, and reminds emergency rescue personnel to avoid the debris flow by lighting up a light or sounding an alarm. Compared with manual monitoring, drone 310 monitoring, and vibration signal monitoring, the present application scheme has the advantages of convenient monitoring, fast feedback speed, and strong adaptability to the environment, and ensures that emergency rescue personnel can evacuate the debris flow area in time when the debris flow breaks out again.

[0046] In addition, the piezoelectric ceramic layer 120 has an insulating layer 160 built therein, and the electrical connector 130 transmits the current generated by the piezoelectric ceramic layer 120 to the signal transmitter 111, which can effectively prevent the current generated by the piezoelectric ceramic layer 120 from being lost and ensure that the signal transmitter 111 transmits signals outward.

[0047] The electrical connector 130 is a conductive copper rod, which has good conductivity, high strength, and is not easily deformed. The insulating layer 160 can be made of engineering plastics, glass fiber, epoxy resin, etc. to realize the vibration monitor with different densities.

[0048] In some embodiments, the monitoring module 110 further includes a locator 112, which is arranged on the inner side of the piezoelectric ceramic layer 120, wherein the locator 112 may have its own battery, which may provide charge for the locator 112, or the piezoelectric ceramic layer 120 may provide charge for the locator 112 through the electrical connector 130 when it is squeezed. Through the setting of the locator 112, the external control system can obtain the movement speed of the real-time monitoring device 100 through the locator 112, and the risk level of the debris flow can be judged according to the change of the movement speed of the real-time monitoring device 100. The alarm device 200 is connected to the control system in communication, and the alarm device 200 sends an alarm to the emergency rescue personnel to avoid the debris flow according to the risk level, which may be an alarm sound or an alarm light. Specifically, when the movement speed of the real-time monitoring device 100 is between v1 and v2, the danger level of the debris flow is level one, which is a general risk at this time, and the alarm device 200 sends a level one danger signal to the emergency rescue personnel through an alarm light or a speaker. When the movement speed of the real-time monitoring device 100 is between v2 and v3, the danger level of the mudslide is level 2, which is a relatively high risk. The alarm device 200 sends a level 2 danger signal to the emergency rescue personnel through the alarm light or speaker. When the movement speed of the real-time monitoring device 100 is between v3 and v4, the danger level of the mudslide is level 3, which is a major risk. The alarm device 200 sends a level 3 danger signal to the emergency rescue personnel through the alarm light or speaker. When the movement speed of the real-time monitoring device 100 is between v4 and v5, the danger level of the mudslide is level 4, which is an extremely high risk. The alarm device 200 sends a level 4 danger signal to the emergency rescue personnel through the alarm light or speaker. <v2<v3<v4。

[0049] The alarm device 200 includes a first-level alarm light, a second-level alarm light, a third-level alarm light, and a fourth-level alarm light. The first-level signal light is a blue signal light, the second-level signal light is a yellow signal light, the third-level signal light is an orange signal light, and the fourth-level signal light is a red signal light. When the danger level of the debris flow is level one, the first-level alarm light emits a blue light to remind emergency rescue personnel that a debris flow with a general risk will occur again; when the danger level of the debris flow is level two, the second-level alarm light emits a yellow light to remind emergency rescue personnel that a debris flow with a greater risk will occur again; when the danger level of the debris flow is level three, the third-level alarm light emits an orange light to remind emergency rescue personnel that a debris flow with a major risk will occur again; when the danger level of the debris flow is level four, the fourth-level alarm light emits a red light to remind emergency rescue personnel that a debris flow with a particularly large risk will occur again.

[0050] In some embodiments, reference Figures 2 to 4The real-time monitoring device 100 also includes an elastic protective shell 140, which defines a protective cavity. The piezoelectric ceramic layer 120 is arranged in the protective cavity and is arranged in contact with the inner wall of the protective cavity; wherein the elastic protective shell 140 can be squeezed to act on the piezoelectric ceramic layer 120, so that the piezoelectric ceramic layer 120 can provide an electric charge to the signal transmitter 111 through the electrical connector 130, so that the signal transmitter 111 can send a signal to the alarm device indicating that a mudslide will occur again.

[0051] Specifically, when a debris flow breaks out, the debris flow acts on the surface of the elastic protective shell 140, and the elastic protective shell 140 acts on the surface of the piezoelectric ceramic layer 120 through elastic deformation. The piezoelectric ceramic layer 120 provides electric charge to the signal transmitter 111 through the electrical connector 130, and the alarm device 200 sends a signal to the emergency rescue personnel that the debris flow breaks out again. Among them, through the setting of the elastic protective shell 140, the elastic protective shell 140 can protect the piezoelectric ceramic layer 120, thereby ensuring the service life of the real-time monitoring device 100.

[0052] Most importantly, refer to Figures 2 to 7 , a real-time monitoring device with an elastic protective shell 140 is used, and the staff can prepare multiple real-time monitoring devices, and the elastic protective shell 140 of each real-time monitoring device has different impact resistance. For example, four real-time monitoring devices are used, namely the first monitoring device, the second monitoring device, the third monitoring device and the fourth monitoring device. The elastic protective shell 140 of the first monitoring device is the first protective shell 141, the elastic protective shell 140 of the second monitoring device is the second protective shell 142, the elastic protective shell 140 of the third monitoring device is the third protective shell 143, and the elastic protective shell 140 of the fourth monitoring device is the fourth protective shell 144. The impact resistance of the first protective shell 141 is less than the impact resistance of the second protective shell 142, the impact resistance of the second protective shell 142 is less than the impact resistance of the third protective shell 143, and the impact resistance of the third protective shell 143 is less than the impact resistance of the fourth protective shell 144.

[0053] When monitoring debris flow, the above four real-time monitoring devices are placed on the surface of the debris flow to be monitored. When a small-scale water flow breaks out in the channel, the second protective shell 142, the third protective shell 143 and the fourth protective shell 144 are not affected, and the first protective shell 141 is squeezed on the surface of the piezoelectric ceramic layer 120, and the signal transmitter 111 is powered on to transmit a signal to the alarm device 200 located in the rescue area, reminding emergency rescue personnel that there is a small-scale flood outbreak upstream, and the risk level of the retaining wall is a general risk, and emergency rescue personnel are requested to avoid it. When a rare debris flow with a small flow rate and a low flow rate breaks out in the channel, the third protective shell 143 and the fourth protective shell 144 are not affected, and the second protective shell 142 is squeezed on the surface of the piezoelectric ceramic layer 120, the signal transmitter 111 is powered on to transmit a signal to the alarm device 200 located in the rescue area, and the alarm device 200 reminds the emergency rescue personnel that the current risk level is a high risk, and asks the emergency rescue personnel and rescue equipment to quickly evacuate the scene, and issues a debris flow outbreak warning to the surrounding areas; when a rare debris flow with a large flow rate and a high flow rate breaks out in the channel, the fourth protective shell 144 is not affected, and the third protective shell 143 is squeezed on the surface of the piezoelectric ceramic layer 120, The signal transmitter 111 is powered on to transmit a signal to the alarm device 200 located in the rescue area. The alarm device 200 reminds emergency rescue personnel that the current risk level is a major risk, and asks emergency rescue personnel to evacuate quickly, notify nearby vehicles to avoid, and report to relevant departments; when a viscous mudslide with a large flow and a high flow rate breaks out in the channel, the fourth protective shell 144 is squeezed on the surface of the piezoelectric ceramic layer 120, and the signal transmitter 111 is powered on to transmit a signal to the alarm device 200 located in the rescue area. The alarm device 200 reminds emergency rescue personnel that the current risk level is an extremely large risk, and asks emergency rescue personnel to quickly evacuate the mudslide accumulation area, and implement traffic control to prohibit people and vehicles from approaching.

[0054] Furthermore, in order to achieve different impact resistance of each elastic protective shell 140, multiple methods can be used. For example, the materials of each elastic protective shell 140 are different, so that the impact resistance of the four elastic protective shells 140 is different. Or, the shapes of each elastic protective shell 140 are different, so that the impact resistance of the four elastic protective shells 140 is different. Figures 4 to 7In the present application, the first protective shell 141, the second protective shell 142, the third protective shell 143 and the fourth protective shell 144 adopt different shapes. The first protective shell 141 is a sphere, the second protective shell 142 is a cube, the third protective shell 143 is a cuboid, and the fourth protective shell 144 is a triangular pyramid. Specific analysis: The impact force F of the debris flow impact force on the real-time monitoring device 100 is positively correlated with the debris flow bulk density, flow velocity and force-bearing body shape coefficient. The force-bearing body shape coefficients of the cube, cuboid, triangular pyramid and sphere are 1.47, 1.33, 1.00, and 1.00, respectively. Under the impact of debris flow with the same bulk density and flow velocity, the impact forces received are from large to small in the following order: cube> cuboid> sphere= triangular pyramid. The starting method of the sphere is rolling, but the rolling friction is much smaller than the sliding friction, so the sphere is most likely to start. The starting method of the cube, triangular pyramid and rectangular parallelepiped is sliding. The greater the impact force, the easier it is to start (the greater the force, the weaker the impact resistance). Therefore, the cube is easier to start, the rectangular parallelepiped is more difficult to start, and the triangular pyramid is the most difficult to start.

[0055] In addition, the elastic protective shell 140 is in the shape of a cube, a cuboid, a sphere, or a triangular pyramid. The elastic protective shell 140 has a simple structure and a low manufacturing cost. The elastic protective shell 140 may also be in other shapes, such as a hexahedron.

[0056] In some embodiments, reference Figure 2 , Figures 3 to 7 The elastic protective shell 140 includes a first shell 145 and a second shell 146, the first shell 145 defines a first groove portion, the second shell 146 defines a second groove portion, and the first groove portion and the second groove portion form a protective cavity when the first shell 145 and the second shell 146 are assembled; wherein the first shell 145 and the second shell 146 are detachably connected so that the outside of the piezoelectric ceramic layer 120 can be assembled with a variety of elastic protective shells 140 with different impact resistance.

[0057] Furthermore, in order to achieve a detachable connection between the first shell 145 and the second shell 146, the first shell 145 and the second shell 146 can adopt a variety of connection methods, for example, the first shell 145 and the second shell 146 are threadedly connected, or the first shell 145 and the second shell 146 are connected by bolts, or the first shell 145 and the second shell 146 are snap-connected.

[0058] In some embodiments, reference Figure 2 The monitoring device also includes a shock absorbing layer 150, which is wrapped around the outer side of the monitoring module 110 and arranged on the inner side of the insulating layer 160. In this way, the shock absorbing layer 150 alleviates the impact on the signal transmitter 111. The shock absorbing layer 150 can be made of foam, and the shock absorbing layer 150 has good shock absorbing effect and low cost.

[0059] According to a second aspect of the present invention, a debris flow monitoring system is disclosed, referring to Figures 1 to 7 , including the above-mentioned real-time monitoring device 100, control system and alarm device 200, multiple real-time monitoring devices 100 are provided, and each real-time monitoring device 100 is used to monitor debris flows of different levels; the control system is communicated with each real-time monitoring device 100 and the signal transmitter 111; the alarm device, the control system controls the alarm device according to the information transmitted by the signal transmitter 111 to remind the rescue personnel to avoid the debris flow.

[0060] Specifically, when monitoring the debris flow to break out again, multiple real-time monitoring devices 100 with different impact resistance can be used. For example, the present application scheme adopts four real-time monitoring devices, namely the first monitoring device, the second monitoring device, the third monitoring device and the fourth monitoring device; wherein, when a small-scale water flow breaks out in the channel, the piezoelectric ceramic layer 120 of the first monitoring device is squeezed to energize the signal transmitter 111, the control system receives the signal transmitted by the signal transmitter 111, and controls the alarm device 200 located in the rescue area to send a signal to the emergency rescue personnel, reminding the emergency rescue personnel that there is a small-scale flood outbreak upstream, and the risk level of the retaining wall is a general risk, and the emergency rescue personnel are requested to avoid it; when a small-flow, low-velocity, dilute debris flow breaks out in the channel, the piezoelectric ceramic layer 120 of the second monitoring device is squeezed to energize the signal transmitter 111, the control system receives the signal of the signal transmitter 111, and controls the alarm device 200 located in the rescue area to send a signal to the emergency rescue personnel, and the alarm device 200 reminds the emergency rescue personnel that the current risk level is a large risk, Emergency rescue personnel and rescue equipment are requested to evacuate the scene quickly, and a debris flow outbreak warning is issued to the surrounding areas; when a rare debris flow with a large flow rate and a high flow rate breaks out in the channel, the piezoelectric ceramic layer 120 of the third monitoring device is squeezed to energize the signal transmitter 111, the control system receives the signal transmitted by the signal transmitter 111, and controls the alarm device 200 located in the rescue area to send a signal to the emergency rescue personnel, the alarm device 200 reminds the emergency rescue personnel that the current risk level is a major risk, and the emergency rescue personnel are requested to evacuate quickly, notify nearby vehicles to avoid, and report to the relevant departments; when a viscous debris flow with a large flow rate and a high flow rate breaks out in the channel, the piezoelectric ceramic layer 120 of the fourth monitoring device is squeezed to energize the signal transmitter 111, the control system receives the signal transmitted by the signal transmitter 111, and controls the alarm device 200 located in the rescue area to send a signal to the emergency rescue personnel, the alarm device 200 reminds the emergency rescue personnel that the current risk level is an extremely large risk, and the emergency rescue personnel are requested to evacuate the debris flow accumulation area quickly, and implement traffic control to prohibit people and vehicles from approaching.

[0061] Furthermore, an elastic protective shell 140 is provided on the outside of each of the real-time monitoring devices 100, and the impact resistance of each of the elastic protective shells 140 is different. For example, four real-time monitoring devices are used, namely the first monitoring device, the second monitoring device, the third monitoring device and the fourth monitoring device, the elastic protective shell 140 of the first monitoring device is the first protective shell 141, the elastic protective shell 140 of the second monitoring device is the second protective shell 142, the elastic protective shell 140 of the third monitoring device is the third protective shell 143, and the elastic protective shell 140 of the fourth monitoring device is the fourth protective shell 144. The impact resistance of the first protective shell 141 is less than the impact resistance of the second protective shell 142, the impact resistance of the second protective shell 142 is less than the impact resistance of the third protective shell 143, and the impact resistance of the third protective shell 143 is less than the impact resistance of the fourth protective shell 144.

[0062] When monitoring debris flow, the above four real-time monitoring devices are placed on the surface of the debris flow to be monitored. When a small-scale water flow breaks out in the channel, the second protective shell 142, the third protective shell 143 and the fourth protective shell 144 are not affected, and the first protective shell 141 is squeezed on the surface of the piezoelectric ceramic layer 120, and the signal transmitter 111 is powered on to transmit a signal to the alarm device 200 located in the rescue area, reminding emergency rescue personnel that there is a small-scale flood outbreak upstream, and the current risk level is general risk, please pay attention to avoid emergency rescue personnel. When a rare debris flow with a small flow rate and a low flow rate breaks out in the channel, the third protective shell 143 and the fourth protective shell 144 are not affected, and the second protective shell 142 is squeezed on the surface of the piezoelectric ceramic layer 120, the signal transmitter 111 is powered on to transmit a signal to the alarm device 200 located in the rescue area, and the alarm device 200 reminds the emergency rescue personnel that the current risk level is a high risk, and asks the emergency rescue personnel and rescue equipment to quickly evacuate the scene, and issues a debris flow outbreak warning to the surrounding areas; when a rare debris flow with a large flow rate and a high flow rate breaks out in the channel, the fourth protective shell 144 is not affected, and the third protective shell 143 is squeezed on the surface of the piezoelectric ceramic layer 120, The signal transmitter 111 is powered on to transmit a signal to the alarm device 200 located in the rescue area.
