If the acquired data is abnormal data, the data is determined to be invalid; if the acquired data is normal data, the data is determined to be valid.

[0034] In an exemplary embodiment, the collection unit of the embodiment of the present disclosure includes a sensor, which can adopt a flat design and be combined with product armor to resist vehicle crushing; the collection unit can be laid on the deck of a ship or in an area where a vehicle containing a vehicle power battery is placed, and can use networks including 5G to transmit the collected battery safety-related information to a vehicle supervision platform.

[0035] In an exemplary embodiment, the vehicle supervision platform of the embodiment of the present disclosure determines safety level information based on whether the determined temperature rise rate and battery safety-related information are within a preset safety level threshold, including:

[0036] When the acquired battery safety-related information is all within a preset safety range and the temperature rise rate is less than a preset first reference rate, determining that the vehicle power battery is in a safe state;

[0040] The first reference rate is lower than the second reference rate.

[0041] In the embodiment of the present disclosure, it is assumed that the collected temperature information, humidity information, and combustion release gas concentration information are T0, P0, and C0, respectively; the corresponding safety intervals are T1, P1, and C1; the corresponding overheating intervals are T2, P2, and C2; and the corresponding combustion intervals are T3, P3, and C3; the first reference rate is 1°C / s, and the second reference rate is 5°C / s. Determining the safety level information based on the battery safety related information may include:

[0042] When T0, P0 and C0 are all in the safe range T1, P1 and C1, and the temperature rise rate dT / dt is less than 1℃ / s, the vehicle power battery is judged to be in a safe state;

[0043] When T0, P0 and C0 are all in the safe range T1, P1 and C1 and the temperature rise rate dT / dt ≥ 1°C / s, the vehicle power battery is judged to be in an overheated state;

[0044] When any one of the parameters T0, P0 and C0 reaches the overheating range T2, P2 and C2 and none of the parameters reaches the combustion range T3, P3 and C3, and / or the temperature rise rate dT / dt ≥ 1°C / s, the vehicle power battery is judged to be in an overheating state;

[0045] When any one of the parameters T0, P0 and C0 reaches the combustion range T3, P3 and C3 and / or the temperature rise rate dT / dt ≥ 5°C / s, it is judged that the vehicle power battery is in a combustion state.

[0046] In an exemplary embodiment, the vehicle supervision platform of the embodiment of the present disclosure further includes an updating unit configured to:

[0047] According to the pre-set update cycle, the security level threshold is updated according to the environmental parameters within the update cycle.

[0048] In an exemplary embodiment, the safety level thresholds of the embodiment of the present disclosure include: the following safety intervals corresponding to the safety state: a safety temperature interval, a safety humidity interval, and a safety combustion release gas concentration interval; the following overheat intervals corresponding to the overheat state: an overheat temperature interval, an overheat humidity interval, and an overheat combustion release gas concentration interval; the following combustion intervals corresponding to the combustion state: a combustion temperature interval, a combustion humidity interval, and a combustion state combustion release gas concentration interval; the update unit is configured to, for each update cycle:

[0049] The safe temperature range is set from the lowest temperature in the current update cycle to the highest temperature that can be reached inside the cabin. The safe humidity range is set from the highest humidity in the cabin to the lowest humidity in the current update cycle. The safe combustion gas concentration range is set from zero to the highest value of the fluctuation in the concentration of combustion gas released by the cabin air.

[0050] The maximum temperature that can be reached inside the cabin during the current update cycle to the ignition temperature of the battery material is set as the overheat temperature range; the minimum humidity of the weather during the current preset cycle to the humidity corresponding to when the vehicle power battery begins to smolder or burn is set as the overheat humidity range; the maximum value of the fluctuation in the concentration of combustion released gas caused by the air inside the cabin during the current update cycle to the concentration of combustion released gas released when the vehicle power battery begins to smolder or burn is set as the overheat combustion released gas concentration range;

[0051] The range above the ignition point temperature of the battery material in the current update cycle is set as the combustion temperature range; the range below the humidity corresponding to when the vehicle power battery in the current update cycle begins to smolder or burn is set as the combustion humidity range; the range above the concentration of the combustion released gas released when the vehicle power battery begins to smolder or burn is set as the combustion state combustion released gas concentration range.

[0052] In the disclosed embodiment, during thermal runaway of the vehicle power battery, the temperature gradually rises, the humidity gradually decreases, and the concentration of the gases released by combustion gradually increases from zero. Therefore, when setting the safe temperature and humidity ranges, it is necessary to comprehensively consider the specific temperature and humidity of the shipping environment, the temperature and humidity inside the cabin, and the temperature and humidity of the vehicle battery itself to ensure the accuracy of the preset interval values. The concentration of gases released by combustion is easily affected by the environment. In the absence of any abnormalities, the safe combustion gas concentration range is set from zero to the highest value of the fluctuation in the concentration of gases released by combustion caused by the air inside the cabin.

[0053] As the vehicle's power battery thermal runaway progresses, it will enter and maintain an overheated state. At this point, the battery temperature will exceed the maximum achievable temperature inside the cabin, but will not yet reach the ignition point of the battery materials. The overheat temperature range is defined as the range from the maximum achievable temperature inside the cabin to the ignition point of the battery materials. The humidity will decrease as the overheating state persists. The overheat humidity range is defined as the range from the lowest humidity to the humidity corresponding to when the battery first begins to smolder / combust. The overheated combustion gas concentration range is defined as the range from the highest fluctuation in the concentration of combustion gases released by the cabin air to the concentration of combustion gases released when the battery first begins to smolder / combust. After smoldering / combusting, the battery enters a combustion state, where the battery temperature rises sharply and is accompanied by deflagration and explosion. The range above the ignition point of the battery materials is defined as the combustion temperature range, the range below the humidity corresponding to when the battery first begins to smolder / combust is defined as the combustion humidity range, and the range above the concentration of combustion gases released when the battery first begins to smolder / combust is defined as the combustion state combustion gas concentration range.

[0054] In an exemplary embodiment, the safety level threshold of the embodiment of the present disclosure can be determined experimentally using relevant technologies during the transportation process.

[0055] In an exemplary embodiment, the processing device in the embodiment of the present disclosure includes: a display module, an audible and visual alarm device, a fire-fighting facility, and a transport tool.

[0056] In an exemplary embodiment, the present disclosure:

[0057] The sound and light alarm device is located in the supervision center and / or the cabin and is configured to: execute the sound and light alarm according to the received processing instructions;

[0058] The fire-fighting facilities include one or more of fire-fighting sprinkler facilities, automatic fire extinguishers, and high-pressure water cannons, and are configured to: initiate corresponding fire-fighting processing tasks according to received processing instructions;

[0059] The transfer tool is configured to: determine whether to transfer the new energy vehicle including the vehicle power battery to a safe disposal area based on the received processing instruction;

[0060] The display module is configured to display a pre-stored cabin plan and determined safety level information.

[0061] In one exemplary embodiment, the vehicle supervision platform of the disclosed embodiment is further configured to send battery safety related information to the processing device;

[0062] The display module in the processing device is further configured to display battery safety related information.

[0063] In an exemplary embodiment, the display module of the embodiment of the present disclosure can also be configured to: display one or any combination of the following information: alarm information corresponding to the safety level, the loading rate of the cabin and historical data, wherein the historical data may include battery safety-related information and / or safety level information within a preset time period.

[0064] In one exemplary embodiment, when the temperature, humidity, and combustion gas concentration information of vehicle power batteries in a certain area are determined to be in an overheated state, the vehicle monitoring platform and the processing equipment simultaneously perform the following four processes:

[0065] 1) The vehicle supervision platform sends safety level information indicating an overheating state to a display module in the processing device. The display module adjusts the display color of the area where the new energy vehicle is located in the cabin plan view, based on the coordinate information of the area where the new energy vehicle is located in the cabin plane, to a predetermined color corresponding to the overheating state. For example, if the safety state is set to green and the overheating state is set to yellow, the area where the new energy vehicle is located in the overheating state will change from green to yellow. In an exemplary embodiment, the vehicle supervision platform of the embodiment of the present disclosure can send temperature information, humidity information, and combustion release gas concentration information to the display module, which will update and display the information. Different predetermined colors can be used for display according to different safety level information.

[0066] 2) The vehicle supervision platform sends a processing instruction corresponding to a preset overheating state to the sound and light alarm device, and executes the sound and light alarm according to the received processing instruction. For example, a yellow sound and light alarm is issued in the preset overheating state;

[0067] 3) The vehicle supervision platform sends a processing instruction corresponding to the overheating state to the fire-fighting equipment in the processing device, and the fire-fighting equipment activates the relevant working state according to the processing instruction. In the embodiment of the present disclosure, the processing instruction can be sent to the fire-fighting equipment through the cabin fire-fighting facility control center. At the same time, the embodiment of the present disclosure can refer to relevant technologies to determine the coordinate information of the new energy vehicle in the cabin plane that has overheated. Based on the coordinate information, the nearest fire-fighting facility is dispatched to the area to perform fire-fighting treatment, for example, by activating the fire sprinkler facilities to extinguish the fire and provide disaster relief, thereby preventing the disaster from escalating.

[0068] 4) The vehicle supervision platform sends a processing instruction corresponding to a preset overheating state to the transfer tool, which can be sent to the transfer tool through the transfer tool control center. The embodiment of the present disclosure refers to relevant technologies to determine the coordinate information of the new energy vehicle and the coordinate information of the safe disposal area, and can select a transfer tool (for example, a forklift) that can achieve the fastest transfer based on the coordinate information. After the transfer tool uses relevant technologies to calculate the fastest route for the new energy vehicle to the safe disposal area, it controls the transfer tool to transfer the new energy vehicle that has overheated in the area to the designated safe disposal area.

[0069] In one exemplary embodiment, when the temperature, humidity, and combustion gas concentration information of vehicle power batteries in a certain area are determined to be in an overheated state, the vehicle monitoring platform and the processing equipment simultaneously perform the following four processes:

[0070] 1) The vehicle supervision platform sends the safety level information as a combustion state to the display module in the processing equipment. The display module adjusts the display color of the area where the new energy vehicle is in the combustion state in the cabin plan view to a predetermined color corresponding to the combustion state based on the coordinate information of the area where the new energy vehicle is located on the cabin plane. For example, the safety state is set to green, the overheating state is set to yellow, and the combustion state is set to red. At this time, the area where the new energy vehicle is in the combustion state is displayed in red. In an exemplary embodiment, the vehicle supervision platform of the embodiment of the present disclosure can send temperature information, humidity information, and combustion release gas concentration information to the display module, and the display module updates the display. According to different safety level information, different preset colors can be used for display, for example, red.

[0071] 2) The vehicle supervision platform sends a processing instruction corresponding to a preset combustion state to the sound and light alarm device, and executes the sound and light alarm according to the received processing instruction, for example, a red sound and light alarm is emitted in the preset combustion state;

[0072] 3) The vehicle supervision platform sends a processing instruction corresponding to the burning state to the fire-fighting equipment in the processing equipment, and the fire-fighting equipment starts the relevant working state according to the processing instruction; the processing instruction of the embodiment of the present disclosure can be sent to the fire-fighting equipment through the cabin fire-fighting facility control center. While sending the processing instruction, the embodiment of the present disclosure can refer to relevant technologies to determine the coordinate information of the new energy vehicle in the overheating state on the cabin plane, and dispatch the nearest fire-fighting facility to the area according to the coordinate information to perform fire-fighting treatment; in an exemplary instance, the embodiment of the present disclosure can refer to relevant technologies to demarcate the area where the new energy vehicle in the burning state and the surrounding area as a nine-square grid area, pre-set the fire-fighting facility number in the nine-square grid area, and the fire-fighting facility number on the fastest route for transferring the new energy vehicle in the burning state to the designated safe disposal area. According to the preset fire-fighting and disaster relief logic, the fire-fighting sprinkler facilities, automatic fire extinguishers, and high-pressure water cannons should be activated to curb the spread of the fire.

[0073] 4) The vehicle supervision platform sends a processing instruction corresponding to a preset combustion state to the transfer tool, which can be sent to the transfer tool through the transfer tool control center. The coordinate information of the new energy vehicle and the coordinate information of the safe disposal area are determined by referring to relevant technologies. The transfer tool that can achieve the fastest transfer can be selected based on the coordinate information. After the transfer tool transfers the new energy vehicle to the safe disposal area through the fastest route calculated by relevant technologies, the transfer tool is controlled to transfer the new energy vehicle in the combustion state in the area to the designated safe disposal area.

[0074] In an exemplary embodiment, the acquisition unit of the embodiment of the present disclosure is further configured to: collect image information of the area where the new energy vehicle is parked, and send the collected image information to the vehicle supervision platform;

[0075] The vehicle supervision platform is also configured to: display received image information to determine the safety status of new energy vehicles;

[0076] In an exemplary embodiment, this embodiment can use a high-definition camera arranged in the parking area of ​​new energy vehicles. The high-definition camera can adjust the viewing angle 360 ​​degrees and collect image information through the high-definition camera; the actual situation on the scene of the area where the new energy vehicles are located is confirmed through the collected image information, and it is determined whether it is a false alarm. If it is a false alarm, the alarm information is eliminated in time. If it is a real alarm, the staff can take active disaster relief measures, such as organizing disaster relief forces to go to the scene to support disaster relief work, increase the intensity and scope of disaster relief of fire-fighting facilities, and manually drive transport tools to transport the affected vehicles to designated safe disposal areas.

[0077] The above-mentioned system of the embodiment of the present disclosure can be powered by solar energy and / or batteries. When powered by solar energy and batteries in dual lines, the system maintenance cycle can reach more than one year.

[0078] The vehicle supervision platform of the disclosed embodiment determines the safety level information of the vehicle's power battery, issues sound and light alarms corresponding to different safety level information, remotely activates fire-fighting facilities of different levels, issues processing instructions to control the automatic driving of the transfer vehicle, and transfers the new energy vehicle to a safe disposal area. Compared with manual disaster relief and manual transfer, it can quickly handle disasters without wasting resources. Compared with manual transfer, automatic driving transfer can reduce contact between personnel and burning vehicles and avoid casualties. Different safety handling decisions are made for vehicle power batteries based on safety level information, which can quickly and reasonably handle fires caused by thermal runaway of vehicle power batteries, thereby improving the safety of vehicle power battery sea transportation.
