Technical Field

[0001] This invention relates primarily to the field of vehicle technology, and more particularly to a temperature monitoring system and a temperature monitoring method. Background Technology

[0002] With the increasing number of new energy vehicles on the road, vehicle fires are occurring frequently. Currently, investigating the causes of vehicle fires presents many difficulties, often only determining whether the cause is external or internal to the vehicle itself. More detailed causes, such as the location of the ignition point and the direction of fire spread, are often difficult to determine with existing technology. This lack of clarity regarding the root cause of the fire hinders technological optimization and the prevention of future accidents. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a temperature monitoring system that allows relevant technical personnel to download data in the background for preliminary analysis before arriving at the accident site, providing valuable information for investigating the cause of a fire.

[0004] The present invention also proposes a temperature monitoring method, wherein the temperature monitoring method uses the above-mentioned temperature monitoring system.

[0006] According to an embodiment of the temperature monitoring system of the present invention, by connecting a central module to a temperature sensing component, when the temperature signal at at least one location detected by the temperature sensing component is abnormal, the central module triggers a data upload function to upload all temperature signals from the temperature sensing component to the background big data center. When a vehicle catches fire, the temperature signal at at least one location detected by the temperature sensing component rises abnormally. The temperature sensing component transmits all temperature signals to the central module, triggering the central module's data upload function. The central module can then upload all temperature signals from the temperature sensing component to the background big data center. This allows relevant technical personnel to download the data in advance for preliminary analysis before arriving at the accident scene, and to determine the location of the fire point based on subsequent data analysis, providing valuable information for investigating the cause of the fire. Furthermore, it avoids damage to the temperature signals of the temperature sensing component after a fire, increasing the reliability of data analysis.

[0007] In some embodiments of the present invention, the central module includes a housing, a storage chip, and a data upload module. The storage chip is located inside the housing and is used to store the temperature signal transmitted by the temperature sensing component. The data upload module is located inside the housing and is used to upload the temperature signal of the temperature sensing component to the background big data center. The storage chip is connected to the data upload module.

[0008] In some embodiments of the present invention, the central module further includes an independent power supply located inside the housing. The independent power supply is connected to both the storage chip and the data upload module and is used to supply power to the central module when at least one temperature signal transmitted by the temperature sensing component changes abnormally.

[0009] In some embodiments of the present invention, the central module is connected to the temperature sensing component via a wiring harness, and the housing has an opening through which the wiring harness passes.

[0010] In some embodiments of the present invention, the housing includes a first housing and a second housing, the first housing defining an installation space, the storage chip and the data upload module being disposed within the installation space; the second housing being fitted over the first housing.

[0011] In some embodiments of the present invention, the housing is a fire-resistant component.

[0012] In some embodiments of the present invention, the temperature sensing component includes a first temperature sensing component and a second temperature sensing component. The first temperature sensing component is connected to the central module and is disposed on the front side of the vehicle for detecting the real-time temperature at multiple locations on the front side of the vehicle. The second temperature sensing component is connected to the central module and is disposed on the rear side of the vehicle for detecting the real-time temperature at multiple locations on the rear side of the vehicle.

[0013] In some embodiments of the present invention, the first temperature sensing component includes an engine temperature sensing component, a motor temperature sensing component, an ambient temperature sensing component, a front air conditioning component, and a first battery temperature sensing component. The engine temperature sensing component is used to detect the temperature of the engine in real time; the motor temperature sensing component is used to detect the temperature of the motor in real time; the ambient temperature sensing component is used to detect the ambient temperature in real time; the front air conditioning temperature sensing component is used to detect the temperature at the front air conditioning vents in real time; and the first battery temperature sensing component is used to detect the temperature of the first battery in real time.

[0014] In some embodiments of the present invention, the second temperature sensing component includes a second battery temperature sensing component, a rear air conditioning temperature sensing component, a charging port temperature sensing component, a vehicle power supply temperature sensing component, and a power distribution box temperature sensing component.

[0015] According to an embodiment of the present invention, a temperature monitoring method using the above-described temperature detection system includes: acquiring the temperature signal of the temperature sensing component; confirming that the temperature signal at at least one location increases by S within a limited time t; and the central module triggering a data upload function to upload the temperature signal of the temperature sensing component to the background big data center.

[0016] According to the temperature monitoring method of this invention, by connecting a central module to a temperature sensing component, when the temperature signal at at least one location detected by the temperature sensing component is abnormal, the central module triggers a data upload function to upload all temperature signals from the temperature sensing component to the background big data center. When a vehicle catches fire, the temperature signal at at least one location detected by the temperature sensing component rises abnormally. The temperature sensing component transmits all temperature signals to the central module, triggering the central module's data upload function. The central module can then upload all temperature signals from the temperature sensing component to the background big data center. This allows relevant technical personnel to download the data in advance for preliminary analysis before arriving at the accident scene, and to determine the location of the fire based on subsequent data analysis, providing valuable information for investigating the cause of the fire. Furthermore, it avoids damage to the temperature signals of the temperature sensing component after a fire, increasing the reliability of data analysis.

[0037] Embodiments of the present invention are described in detail below.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The following is for reference. Figures 1-3A temperature monitoring system 100 according to an embodiment of the present invention is described.

[0041] like Figure 1 As shown, the temperature monitoring system 100 according to an embodiment of the present invention includes a temperature sensing component 1 and a central module 2.

[0042] Specifically, the temperature monitoring system 100 is used in vehicles. This system can monitor temperature changes inside the vehicle (such as the passenger compartment and engine compartment) in real time, ensuring that goods (such as food, medicine, and other temperature-controlled commodities) or vehicle components (such as the engine and tires) operate within a suitable temperature range. This helps to detect temperature anomalies promptly, preventing damage to goods or vehicle malfunctions caused by excessively high or low temperatures.

[0043] The temperature sensing component 1 is used to detect the real-time temperature at multiple locations on the vehicle. The temperature sensing component 1 can detect the temperature at multiple locations on the vehicle in real time. For example, the temperature sensing component 1 consists of multiple temperature sensors. These multiple temperature sensors can sense the temperature information at multiple locations on the vehicle being measured and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording and control.

[0044] like Figure 1 As shown, the central module 2 is connected to the temperature sensing component 1. The central module 2 is used to trigger the data upload function when the temperature signal detected by the temperature sensing component 1 at at least one location is abnormal, uploading all temperature signals from the temperature sensing component 1 to the backend big data center 2000. It can be understood that when a vehicle catches fire, the temperature signal detected by the temperature sensing component 1 at at least one location rises abnormally. The temperature sensing component 1 transmits all temperature signals to the central module 2, triggering the data upload function of the central module 2. The central module 2 can then upload all temperature signals from the temperature sensing component 1 to the backend big data center 2000. This allows relevant technical personnel to download the data in advance for preliminary analysis before arriving at the accident scene, and to determine the location of the fire based on subsequent data analysis, which is of reference value for investigating the cause of the fire. Furthermore, it can prevent damage to the temperature signal of the temperature sensing component 1 after a fire, increasing the reliability of data analysis.

[0045] According to an embodiment of the present invention, the temperature detection system connects the central module 2 to the temperature sensing component 1. When the temperature signal detected by the temperature sensing component 1 at at least one location is abnormal, the central module 2 triggers the data upload function to upload all temperature signals from the temperature sensing component 1 to the background big data center 2000. When a vehicle catches fire, the temperature signal detected by the temperature sensing component 1 at at least one location rises abnormally. The temperature sensing component 1 transmits all temperature signals to the central module 2, triggering the data upload function of the central module 2. The central module 2 can then upload all temperature signals from the temperature sensing component 1 to the background big data center 2000. This allows relevant technical personnel to download the data in advance for preliminary analysis before arriving at the accident scene, and to determine the location of the fire based on subsequent data analysis, providing valuable information for investigating the cause of the fire. Furthermore, it avoids damage to the temperature signals of the temperature sensing component 1 after a fire, increasing the reliability of data analysis.

[0046] In some embodiments of the present invention, such as Figure 1 As shown, the temperature sensing component 1 includes a first temperature sensing component 11 and a second temperature sensing component 12. The first temperature sensing component 11 is connected to the central module 2 and is located on the front side of the vehicle to detect the real-time temperature at multiple locations on the front side of the vehicle. The second temperature sensing component 12 is connected to the central module 2 and is located on the rear side of the vehicle to detect the real-time temperature at multiple locations on the rear side of the vehicle. It can be understood that the temperature sensing components 1 are relatively dispersed. The first temperature sensing component 11 and the second temperature sensing component 12 detect the real-time temperature at the front and rear sides of the vehicle respectively. Dividing the temperature sensing components 1 into two groups to detect the real-time temperature at multiple locations on the vehicle can prevent simultaneous failure of the temperature sensing components 1 and facilitate the layout and installation of the temperature sensing components 1.

[0047] Furthermore, such as Figure 1 As shown, the first temperature sensing component 11 includes an engine temperature sensing component 111, a motor temperature sensing component 112, an ambient temperature sensing component 113, a front air conditioning temperature sensing component 114, and a first battery temperature sensing component 115. The engine temperature sensing component 111 is used to detect the engine temperature in real time, the motor temperature sensing component 112 is used to detect the motor temperature in real time, the ambient temperature sensing component 113 is used to detect the ambient temperature in real time, the front air conditioning temperature sensing component 114 is used to detect the temperature at the front air conditioning vents in real time, and the first battery temperature sensing component 115 is used to detect the temperature of the first battery in real time.

[0048] In this embodiment, as Figure 1As shown, the engine temperature sensing component 111 includes an engine intake air temperature sensor 1111 and an engine coolant temperature sensor 1112, which can detect the engine intake air temperature and coolant temperature in real time, making it easier to observe the engine status and increase the reliability of the engine's working status; the motor temperature sensing component 112 includes a drive motor temperature sensor 1121 and a motor controller temperature sensor 1122, which can detect the real-time temperature of the drive motor and motor controller 5, making it easier to observe the motor status and increase the reliability of the motor's working status; the ambient temperature sensing component 113 includes a left ambient temperature sensor 1131 and a right ambient temperature sensor 1132, which can detect the ambient temperature on the left and right sides of the vehicle respectively, and can comprehensively judge the ambient temperature outside the vehicle, avoiding the influence of engine and other components on the judgment of ambient temperature; the front air conditioning temperature sensing component 114 includes a passenger-side air conditioning vent temperature sensor 1141, a central control air conditioning vent temperature sensor 1142, and a driver-side air conditioning vent temperature sensor 1143, which can detect the temperature of multiple air vents in the front of the vehicle, comprehensively judge the air conditioning effect of the front air conditioning, and facilitate the vehicle's air conditioning controller to adjust the temperature of the front air conditioning.

[0049] like Figure 1 As shown, the first battery temperature sensing component 115 includes a first battery temperature sensor 1151. The first battery is the vehicle's small battery. When the engine starts, the small battery supplies power to the starter motor, ignition system, and other major electrical devices to ensure smooth engine startup. When the engine is not running or running at low speed, the small battery supplies power to various electrical devices, such as the entertainment system, lighting system, doors, and windows, ensuring these devices function normally even when the engine is not running at full power. Furthermore, when there are too many electrical devices and the power consumption exceeds the generator's supply capacity, the small battery also assists the generator in supplying power to various electrical devices. In emergencies, when critical systems such as the braking system, airbag sensor, speed sensor, instrument panel, lighting system, and power steering require power, the small battery can provide necessary power support to ensure safe vehicle operation. In pure electric vehicles, the small battery also controls the switching of the power battery. Before the vehicle starts, the high-voltage power battery is off by default, requiring a small battery as a low-voltage power source to drive the relay, thereby opening the power battery switch. Once the switch is open, the high-voltage power battery charges the small battery. Small batteries also have the function of stabilizing voltage, which is equivalent to a large capacitor. They can absorb instantaneous overvoltage in the circuit and protect electrical equipment from damage caused by voltage fluctuations.

[0050] like Figure 1 As shown, the first battery temperature sensing component 115 can detect the temperature of the first battery in real time, making it easier to observe the status of the first battery and increasing the reliability of the working status of the first battery.

[0051] Furthermore, such as Figure 1As shown, the second temperature sensing component 12 includes a second battery temperature sensing component 121, a rear air conditioning temperature sensing component 122, a charging port temperature sensing component 123, a vehicle power supply temperature sensing component 124, and a power distribution box temperature sensing component 125. The second battery temperature sensing component 121 is used to detect the temperature of the second battery in real time, the rear air conditioning temperature sensing component 122 is used to detect the temperature at the rear air conditioning vent in real time, the charging port temperature sensing component 123 is used to detect the temperature at the charging port in real time, the vehicle power supply temperature sensing component 124 is used to detect the temperature at the vehicle power supply in real time, and the power distribution box temperature sensing component 125 is used to detect the temperature at the power distribution box in real time.

[0052] It is understood that the second battery temperature sensing component 121 includes a battery pack temperature sensor 1211. The second battery is a battery pack, which is a high-voltage device used in new energy vehicles to store electrical energy. It is typically composed of multiple lithium battery cells connected in series and parallel. These individual batteries work together to provide the power required by the vehicle, ensuring that the vehicle can operate normally. The second battery temperature sensing component 121 can detect the temperature of the second battery in real time, facilitating the observation of the second battery's status and increasing the reliability of the second battery's operation.

[0053] like Figure 1 As shown, the rear air conditioning temperature sensing component 122 includes a right rear foot vent temperature sensor 1221, a rear knee vent temperature sensor 1222, and a left rear foot vent temperature sensor 1223. It can detect the temperature of multiple vents in the rear of the vehicle, comprehensively assess the airflow effect of the rear air conditioning, and facilitate the vehicle's air conditioning controller in adjusting the rear air conditioning temperature. The charging port temperature sensing component 123 includes a charging port temperature sensor 1231, which can detect the charging port temperature in real time, facilitating observation of the charging port's status and increasing the reliability of the charging port's operation. The vehicle power supply temperature sensing component 124 includes a vehicle power supply temperature sensor... Sensor 1241, the vehicle power supply can convert the 12V DC power from the vehicle battery into a stable voltage and current, providing the necessary power to various electronic devices in the vehicle, ensuring the normal operation of the devices, and avoiding equipment damage or performance degradation caused by voltage fluctuations. The vehicle power supply temperature sensor 1241 can detect the temperature of the vehicle power supply in real time, making it easier to observe the status of the vehicle power supply and increasing the reliability of the charging port's working status; the power distribution box temperature sensing assembly 125 includes a power distribution box temperature sensor 1251, which can detect the temperature of the power distribution box, making it easier to observe the status of the power distribution box and increasing the reliability of the power distribution box's working status.

[0054] In some embodiments of the present invention, such as Figure 3As shown, the central module 2 includes a housing 21, a storage chip 22, and a data upload module 23. The storage chip 22 is located inside the housing 21 and is used to store the temperature signals transmitted by the temperature sensing component 1. It can record temperature data from multiple locations on the vehicle, facilitating the analysis of the vehicle's fire location and the direction of fire spread in the event of an accident. For example, the data collected by the temperature sensing component 1 is as follows:

[0055]

[0056]

[0057] Table 1 Temperature signals transmitted from the temperature sensing component to the memory chip

[0058] Among them, the following sensors are included: No. 1 Engine intake air temperature sensor 1111, No. 2 Engine coolant temperature sensor 1112, No. 3 Drive motor temperature sensor 1121, No. 4 Motor controller temperature sensor 1122, No. 5 Ambient temperature sensor, No. 6 Ambient temperature sensor, No. 7 Passenger side air conditioning vent temperature sensor 1141, No. 8 Central air conditioning vent temperature sensor 1142, No. 9 Driver's side air conditioning vent temperature sensor 1143, No. 10 Small battery temperature sensor, No. 11 Battery pack temperature sensor 1211, No. 12 Right rear footwell vent temperature sensor 1221, No. 13 Rear knee vent temperature sensor 1222, No. 14 Left rear footwell vent temperature sensor 1223, No. 15 Charging port temperature sensor 1231, No. 16 Vehicle power supply temperature sensor 1241, and No. 17 Distribution box temperature sensor 1251.

[0059] The following temperature change process can be analyzed:

[0060] At 0 seconds, all temperature sensors showed the same value of 20℃. At 20 seconds, the values ​​of temperature sensors 12, 13, and 14 first changed and increased, with temperature sensor 14 reaching a maximum value of 25℃. At 40 seconds, the temperatures of temperature sensors 12, 13, and 14 continued to rise, and the values ​​of temperature sensors 7, 8, and 9 also began to rise; the value of temperature sensor 14 reached a maximum of 40℃. At 60 seconds, the signal of temperature sensor 10 began to rise. At 80 seconds, the signals of temperature sensors 5 and 6 began to rise; the value of temperature sensor 14 reached a maximum of 200℃, which was its upper limit.

[0061] Temperature sensors 7, 8, 9, 10, 12, 13, and 14 are all located inside the passenger compartment 200, with temperature sensor 14 located at the rear air conditioning vent of the driver's seat.

[0062] The above temperature change process leads to the preliminary conclusion that the fire started in the rear seats of passenger compartment 200, near the driver's seat, and gradually spread to the front seats (driver and front passenger). Temperature sensor #14 is located at the rear air conditioning vent behind the driver's seat; there are no other electrical components in this location, making it highly unlikely that the fire was caused by any electrical components. Therefore, it is highly probable that the fire was caused by items left in the rear seats of passenger compartment 200, and the fire was ultimately caused by a vehicle malfunction.

[0063] In this embodiment, the storage module adopts a self-overwriting storage method with a storage period of 7 days. After 7 days, new data will automatically overwrite the old data, so that it always stores the temperature data of the most recent 7 days.

[0064] like Figure 3 As shown, the data upload module 23 is located inside the housing 21 and is used to upload the temperature signal of the temperature sensing component 1 to the background big data center 2000. The storage chip 22 is connected to the data upload module 23. When a fire occurs in the vehicle, the temperature signal in the storage chip 22 can be uploaded to the background big data processing center in a timely manner. This allows relevant technical personnel to download the data in advance for preliminary analysis before arriving at the accident scene. The data analysis can also help determine the location of the fire, which is of reference value for investigating the cause of the fire. Furthermore, it can prevent the temperature signal of the temperature sensing component 1 from being damaged after a fire, increasing the reliability of the data analysis.

[0065] In addition, the housing 21 can protect the storage chip 22 and the data upload module 23, preventing damage to the storage chip 22 and the data upload module 23.

[0066] Furthermore, such as Figure 3 As shown, the central module 2 also includes an independent power supply 24, which is located inside the housing 21. The independent power supply 24 is connected to both the storage chip 22 and the data upload module 23, and is used to supply power to the central module 2 when at least one temperature signal transmitted by the temperature sensing component 1 changes abnormally. In normal operating mode, the central module 2 is directly powered by an external power supply. In emergency situations, the independent battery is triggered. When a rapid increase in the temperature signal of the temperature sensing component 1 is detected, the independent battery is triggered to directly power the central module 2, preventing the central module 2 from stopping operation due to loss of power supply caused by damage to the external power supply.

[0067] In some embodiments of the present invention, such as Figure 3As shown, the central module 2 and the temperature sensing component 1 are connected by a wiring harness 3. An opening 213 is provided on the housing 21, and the wiring harness 3 passes through the opening 213. This allows the wiring harness 3 to pass through the housing 21 relatively smoothly, achieving the connection between the central module 2 and the temperature sensing component 1. In this embodiment, the opening 213 includes a first opening 2131 and a second opening 2132. The first temperature sensing component 11 passes through the first opening 2131, and the second temperature sensing component 12 passes through the second opening 2132. Both the first temperature sensing component 11 and the second temperature sensing component 12 can be reliably connected to the central module 2.

[0068] In addition, such as Figure 2 and Figure 3 As shown, the temperature monitoring system 100 also includes an engine controller 4, a motor controller 5, a vehicle control unit 6, an air conditioning control unit 7, a battery management control unit 8, and an on-board control unit 9. The central module 2 can be connected to the engine controller 4, motor controller 5, vehicle control unit 6, air conditioning control unit 7, battery management control unit 8, and on-board control unit 9 via wiring harnesses 3. The housing 21 is provided with a third port 2133. The wiring harnesses 3 connecting the central module 2 to the engine controller 4, motor controller 5, vehicle control unit 6, air conditioning control unit 7, battery management control unit 8, and on-board control unit 9 pass through the third port 2133, which can send the temperature signal transmitted by the temperature sensing component 1 to at least one of the engine controller 4, motor controller 5, vehicle control unit 6, air conditioning control unit 7, battery management control unit 8, and on-board control unit 9, so that the engine controller 4, motor controller 5, vehicle control unit 6, air conditioning control unit 7, battery management control unit 8, and on-board control unit 9 can perform adaptive operations based on the temperature signal.

[0069] In some embodiments of the present invention, such as Figure 3 As shown, the housing 21 includes a first housing 211 and a second housing 212. The first housing 211 defines an installation space, within which the storage chip 22 and the data upload module 23 are located. The second housing 212 is fitted over the first housing 211. The second housing 212 can effectively protect the first housing 211 and the storage chip 22 and data upload module 23 located within it. The first housing 211 and the second housing 212 can jointly protect the storage chip 22 and the data upload module 23, ensuring that the storage chip 22 of the central module 2 is preserved to the maximum extent after the vehicle catches fire, completely recording the changes of each temperature sensor throughout the entire fire process.

[0070] Furthermore, the housing 21 is a fire-resistant component. For example, both the first housing 211 and the second housing 212 are silicon dioxide components, which can minimize the risk of damage to the first housing 211 and the second housing 212 when the vehicle catches fire, and maximize the preservation of the storage chip 22 after the vehicle catches fire, so as to completely record the changes of each temperature sensor throughout the entire fire process.

[0071] The temperature monitoring method according to embodiments of the present invention, such as Figure 1 and Figure 4 As shown, using the aforementioned temperature monitoring system 100, the temperature monitoring method includes: acquiring the temperature signal of the temperature sensing component 1; confirming that the temperature signal at at least one location rises by S within a limited time t; and the central module 2 triggering the data upload function to upload the temperature signal of the temperature sensing component 1 to the background big data center 2000. That is, when the temperature signal abnormally rises within a short period, the central module 2 triggers the data upload function to upload the temperature signal of the temperature sensing component 1 to the background big data center 2000. This ensures that the central module 2 only uploads the temperature signal of the temperature sensing component 1 to the background big data center 2000 when there is a risk of a fire, avoiding frequent data uploads and preventing excessive pressure on the background big data center 2000.

[0072] According to the temperature monitoring method of this invention, by connecting the central module 2 to the temperature sensing component 1, when the temperature signal at at least one location detected by the temperature sensing component 1 is abnormal, the central module 2 triggers the data upload function to upload all temperature signals of the temperature sensing component 1 to the background big data center 2000. When a vehicle catches fire, the temperature signal at at least one location detected by the temperature sensing component 1 rises abnormally. The temperature sensing component 1 transmits all temperature signals to the central module 2, triggering the data upload function of the central module 2. The central module 2 can then upload all temperature signals of the temperature sensing component 1 to the background big data center 2000. This allows relevant technical personnel to download the data in advance for preliminary analysis before arriving at the accident scene, and to determine the location of the fire point based on subsequent data analysis, which is of reference value for investigating the cause of the fire. Furthermore, it avoids damage to the temperature signal of the temperature sensing component 1 after a fire, increasing the reliability of data analysis.

[0073] In some embodiments of the present invention, the time limit t satisfies: t≤3 seconds. It can be understood that the time limit is no greater than 3 seconds, meaning that when the temperature rises abnormally within 3 seconds, all temperature signals from the temperature sensing component 1 are uploaded to the background big data center 2000. This aligns with the temperature development trend during a vehicle fire. The temperature sensing component 1 transmits all temperature signals to the central module 2, triggering the data upload function of the central module 2. The central module 2 can then upload all temperature signals from the temperature sensing component 1 to the background big data center 2000. This allows relevant technical personnel to download the data in advance for preliminary analysis before arriving at the accident scene, and to determine the location of the ignition point based on subsequent data analysis, providing valuable information for investigating the cause of the fire.

[0074] In some embodiments of the present invention, it is confirmed that the temperature signal at at least one location rises by S within a limited time t, satisfying: S≥30℃. It is understood that when the temperature rises by at least 30℃ within 3 seconds, all temperature signals from the temperature sensing component 1 are uploaded to the background big data center 2000. This aligns with the temperature development trend during a vehicle fire. The temperature sensing component 1 transmits all temperature signals to the central module 2, triggering the data upload function of the central module 2. The central module 2 can then upload all temperature signals from the temperature sensing component 1 to the background big data center 2000. This allows relevant technical personnel to download data in advance for preliminary analysis before arriving at the accident scene, and to determine the location of the ignition point based on subsequent data analysis, providing valuable information for investigating the cause of the fire.

[0075] In some embodiments of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the temperature monitoring method also includes: confirming that the vehicle is powered on; and transmitting the temperature signal of the temperature sensing component 1 to the storage chip 22 of the central module 2. It can be understood that when the vehicle is in sleep mode, the temperature sensor uses the vehicle's constant power to detect the temperature in real time. When the vehicle is powered on, the temperature signal of the temperature sensing component 1 is transmitted to the storage chip 22 of the central module 2, thereby recording the temperature signal of the vehicle in sleep mode.

[0076] In some embodiments of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the temperature monitoring method also includes: confirming that the vehicle is not powered on; confirming that the temperature signal interval limit value T of the temperature sensing component 1 has not been uploaded to the central module 2; and transmitting the temperature signal of the temperature sensing component 1 to the storage chip 22 of the central module 2. That is, when the vehicle is not powered on for a long time, the temperature signal of the temperature sensing component 1 is automatically transmitted to the storage chip 22 of the central module 2, so as to avoid the temperature signal of the temperature sensing component 1 being stored at the temperature sensing component 1 for a long time and to avoid the loss of the temperature signal of the temperature sensing component 1.

[0077] In some embodiments of the present invention, the limiting value T satisfies: 24 hours ≤ T ≤ 48 hours. It is understood that the temperature signal interval limiting value T of the temperature sensing component 1 can be 24 hours, 25 hours, 26 hours, 27 hours, 28 hours, 29 hours, 30 hours, 31 hours, 32 hours, 33 hours, 34 hours, 35 hours, 36 hours, 37 hours, 38 hours, 39 hours, 40 hours, 41 hours, 42 hours, 43 hours, 44 hours, 45 hours, 46 hours, 47 hours, or 48 hours. This makes the limiting value more reasonable and avoids the loss of temperature signal from the temperature sensing component 1.
