[0027] In order to make the technical means, creative features, purposes and effects achieved by the application easy to understand, the high-temperature-resistant multi-sensor fusion device and system of the application are specifically described below in conjunction with the drawings.

[0028] The high-temperature resistant multi-sensor fusion device includes: a high-temperature resistant housing 10, a cylinder 20, and a detection system.

[0029] like Figure 1 As shown, the high-temperature resistant outer shell 10 includes: a high-temperature resistant outer jacket 11, a high-temperature resistant inner liner 12, and an insulation layer 13. The insulation layer 13 is sandwiched between the high-temperature resistant outer jacket 11 and the high-temperature resistant inner liner 12.

[0030] In this embodiment, the high-temperature resistant outer jacket 11 and the high-temperature resistant inner liner 12 are made of nano-ceramics, and the insulation interlayer 13 is made of rock wool.

[0031] A first steel frame 17 is provided between the high-temperature resistant outer jacket 11 and the insulation interlayer 13, and a second steel frame 18 is provided between the insulation interlayer 13 and the high-temperature resistant inner liner 12. A positioning member 15 is provided between the first steel frame 17 and the second steel frame 18 to determine the position between the first steel frame 17 and the second steel frame 18. The first steel frame 17 and the second steel frame 18 are used to support the insulation interlayer, making the structure of the high-temperature resistant outer shell 10 more stable. Specifically, the second steel frame 18 includes a second steel frame body and a cover, while the first steel frame 17 has no cover.

[0032] An adjustable mounting bracket 19 is provided on the outer surface of the high-temperature resistant jacket 11. The high-temperature resistant multi-sensor fusion device is fixed in the required installation position by the adjustable mounting bracket 19. During installation, a level is required for calibration.

[0033] The high-temperature resistant outer jacket 11, the high-temperature resistant inner liner 12, and the insulation layer 13 all include a main body and a cover. The high-temperature resistant outer shell also has a wiring hole 110, specifically, the wiring hole 110 is located on the cover. The wiring hole 110 can be an antenna wiring hole, a charging hole, or a solar charging port, mainly used to meet functional expansion needs.

[0034] The cylinder 20 has a hollow structure and penetrates the high-temperature resistant outer shell 11, the insulation layer 13, and the high-temperature resistant inner liner 12. The cylinder 20 is adjustablely mounted on the high-temperature resistant outer shell 11. Specifically, the cylinder 20 is threaded onto the high-temperature resistant outer shell 11, and rotating the cylinder 20 adjusts the depth to which it extends into the high-temperature resistant inner liner 12. Specifically, the cylinder 20 is mounted on the cover.

[0035] like Figure 3 As shown, the detection system includes: a temperature sensor 31, multiple tilt sensors 32, a vibration sensor 33, a GPS module 34, a communication module 35, a processor 36, a power supply 37, and a switch 38.

[0036] Temperature sensor 31 is used to measure temperature. Temperature sensor 31 is installed inside the hollow structure of cylinder 20, and is located at the end of cylinder 20 facing the outside of the high-temperature resistant housing 10.Figure 1 The temperature sensor 31 is installed at the upper end of the cylinder 20, and the head of the temperature sensor 31 is directed to the upper end of the cylinder 20. In the embodiment, the middle section of the wire connected with the temperature sensor 31 is spiral-shaped. Thus, when the temperature sensor 31 rotates with the cylinder 20, the other end of the wire connected with the temperature sensor 31 will not be pulled, thereby ensuring the service life.

[0037] The plurality of inclination sensors 32, the vibration sensor 33, the GPS module 34, the communication module 35, the processor 36, the power supply 37, and the switch 38 are installed in the high-temperature-resistant inner container 12.

[0038] The temperature sensor 31, the plurality of inclination sensors 32, the vibration sensor 33, the GPS module 34, the communication module 35, the processor 36, the power supply 37, and the switch 38 form a detection loop. The power supply 37 is connected with the processor 36, the processor 36 is connected with the plurality of inclination sensors 32, the temperature sensor 31, the vibration sensor 33, the GPS module 34, and the communication module 35, and the switch 38 is connected on the main loop of the detection system and is used to control whether the power supply 38 supplies power to the detection system. Specifically, the switch 38 is connected on the line connecting the power supply 37 and the processor 36. The switch 38 corresponds to the cylinder 20, and adjusting the distance of the cylinder 20 extending into the high-temperature-resistant outer shell 10 can trigger the switch 38 to close.

[0039] The inclination sensors 32 are used to measure inclination data, the vibration sensor 33 is used to measure the vibration of an object, and the GPS module is used to locate the position of the high-temperature-resistant multi-sensor fusion device. The processor 36 packages the temperature data, the inclination data, the vibration data, the GPS positioning data, and the time data at regular intervals and sends them to the cloud platform 200 through the communication module 35.

[0040] Specifically, the inclination sensor 32 is a high-temperature-resistant wireless inclination sensor. The power supply 37 is a rechargeable power supply.

[0041] In the embodiment, the high-temperature-resistant inner container 12 is provided with inclination sensor positioning columns 14 on the inner side, the positioning member 15 is a positioning hole, the positioning hole is provided with a positioning bolt 16, each inclination sensor 32 is installed on an inclination sensor positioning column 14, and the inclination sensor 32 is fixed by the positioning bolt 16 and the inclination sensor positioning column 14. Specifically, the two ends of the positioning hole are provided with bolts, and the positioning bolt 16 is installed at the end directed to the inside of the high-temperature-resistant inner container 12.

[0042] In the embodiment, the detection system further comprises a storage module 39 and an indicator light 310, both of which are connected with the processor 36. The storage module 39 is used to store the data collected by the temperature sensor 31, the plurality of inclination sensors 32 and the vibration sensor 33. The indicator light 310 displays the working state of the inclination sensor 32 through transformation modes such as constant light, flickering, color transformation, etc. Specifically, when the switch 38 is closed to electrify and initialize the inclination sensor 32, the indicator light 310 emits blue light. The indicator light 310 intermittently flashes blue light in the communication connection state. After the communication connection is normal, the indicator light 310 starts to work. When the indicator light 310 is in normal working state, it emits green light and intermittently flashes. A transparent column 111 is further arranged on one side of the high-temperature-resistant shell 10. The transparent column 111 penetrates through the high-temperature-resistant shell 11, the heat-insulating layer 13 and the high-temperature-resistant inner container 12. The state of the indicator light 310 can be displayed through the transparent column 111, so as to determine the working state of the inclination sensor 32.

[0043] As shown in Figure 4 The high-temperature-resistant multi-sensor monitoring system comprises a high-temperature-resistant multi-sensor fusion device, a cloud platform 200 and a terminal platform 300. The cloud platform 200 is in communication connection with the high-temperature-resistant multi-sensor fusion device. The cloud platform 200 receives the inclination data, vibration data, temperature data, GPS positioning data and time data sent by the high-temperature-resistant multi-sensor fusion device, and analyzes and processes these data. The terminal platform 300 is in communication connection with the cloud platform 200. The terminal platform 300 receives the data sent by the cloud platform 200, and analyzes the received data. Specifically, the terminal platform 300 sets a certain threshold value for the inclination data, vibration data and temperature data, and judges the warning level through the threshold value of each data. According to these data, the risk level of the measured structure is inferred through the structural change quantity value algorithm, so as to provide data support for early warning.

[0044] Under normal circumstances, the multi-sensor fusion device is in a dormant state, and low-frequency data acquisition and transmission (such as once every 5 minutes) are performed to ensure low power consumption. The high-temperature-resistant multi-sensor fusion device supports regulating and controlling the acquisition frequency, and supports automatic wake-up acquisition when the threshold value is exceeded. The processor 36 of the multi-sensor fusion device sets a certain threshold value for the values or frequencies of the inclination data, vibration data and temperature data. When the values or frequencies of any one of the inclination data, vibration data and temperature data received by the processor 36 exceed the set threshold value, automatic wake-up acquisition is realized. The high-temperature-resistant multi-sensor fusion device is converted to high-frequency data acquisition and transmission (such as 100 Hz). If the data is continuously changing after wake-up, it indicates that the measured structure in the environment has actually changed. According to the algorithm of the corresponding structural change, the risk level of the structure is inferred.

[0045] Specifically, the high-temperature-resistant multi-sensor fusion device further comprises an alarm module connected with the processor 36. When the terminal platform 300 judges that there is a risk, an alarm will be sent, and a signal will be sent to the high-temperature-resistant multi-sensor fusion device. The processor 36 controls the alarm module to alarm.

[0046] As shown in Figure 5 The following are the main reasons for the collapse of the building. 1. Different building material structures change under high temperature. Wooden structures will be carbonized, steel structures will be plastically deformed under high temperature for a period of time, and brick and concrete structures are prone to cracks and structural collapse. 2. Fire load, the total energy released by combustible materials in the building volume. 3. Explosion, the combination of combustible materials and oxidizing agents. 4. External force, the increase in the load of the building structure caused by water spraying during rescue, and the structural cracks and collapse caused by thermal expansion and contraction. 5. There are illegal buildings, overloading, and destruction of the main structure. Combining the above different main reasons, the relationship between the change of the corresponding material structure and the time-temperature after the fire of different materials is summarized, and the potential collapse risk is evaluated by algorithm; if the fire load is large, the relationship between time and temperature can be used to judge the damage of high temperature to the structure in a short time, and deformation and vibration data can be used as evidence, if there is an explosion, the GPS positioning data of the sensor can be used to determine whether the sensor has been displaced due to the explosion, to determine the range of the explosion, and to actively avoid the risk point. The above risk possibilities are used to establish a mathematical model to accurately analyze the ongoing risks, develop an alarm plan, and accumulate data for better precision rescue data support.

[0047] The above embodiments are preferred cases of the present application and do not limit the protection scope of the present application.
