[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] According to one aspect of an embodiment of the present application, a vehicle abnormality handling system is provided. Optionally, in this embodiment, the vehicle abnormality handling system can be applied to Figure 1 In the hardware environment composed of the new energy vehicle 102 and the server 104 shown in FIG. Figure 1 As shown, the server 104 is connected to the new energy vehicle 102 via a network, and can be used to provide services (such as application services, etc.) for the new energy vehicle 102 or the on-board terminal on the new energy vehicle 102. A database can be set on the server 104 or independently of the server 104 to provide data storage services for the server 104.

[0028] The above network may include but is not limited to at least one of the following: wired network, wireless network. The above wired network may include but is not limited to at least one of the following: wide area network, metropolitan area network, local area network, and the above wireless network may include but is not limited to at least one of the following: WIFI (Wireless Fidelity), Bluetooth.

[0029] The vehicle abnormality detection system of the embodiment of the present application can be applied to a new energy vehicle 102. Figure 2 is a schematic diagram of the structure of an optional vehicle abnormality handling system according to an embodiment of the present application, such as Figure 2 As shown, the above-mentioned vehicle abnormality handling system includes multiple sampling devices 201, a first transmission pipeline 202 and a designated processing unit 203, wherein each of the multiple sampling devices 201 is arranged at a sampling point among multiple sampling points inside the body of the new energy vehicle, and the first transmission pipeline 202 is used to connect the multiple sampling devices 201 and the designated processing unit 203.

[0030] The vehicle abnormality handling system in this embodiment can be applied to the field of intelligent driving, and can be used in the scenario of safety monitoring of new energy vehicles. Unlike traditional vehicles, new energy vehicles usually use high-energy-density battery packs as power sources. With the development of new energy vehicles, the battery life and energy density have increased year by year. As an important energy storage unit for new energy vehicles, battery packs or battery packs are generally composed of ternary lithium batteries, lithium iron phosphate batteries, etc. The above-mentioned battery packs or battery packs are generally distributed under the vehicle and arranged in a flat manner according to specific rules to form a larger battery pack. These batteries may cause thermal runaway and then explosion when overcharged, over-discharged, short-circuited or physically damaged. In addition, the electrical architecture of new energy vehicles is more complex, and the electrical system therein will generate high temperatures during operation, increasing the risk of explosion.

[0031] Although the current battery pack has battery management, it can monitor and protect the battery from overvoltage and overcurrent. However, the existing BMS (Battery Management System, or power management circuit) cannot prevent and avoid the risk of explosion caused by abnormal failure, impact, and high temperature of lithium batteries. In addition, the initial explosion of batteries is generally caused by local points, which will quickly spread in a short period of time, causing large-scale explosion and fire of battery packs, posing great risks to vehicles and personnel. In addition, in addition to battery packs, new energy vehicles may also have other flammable, explosive or high-risk components, such as components belonging to high-voltage electrical systems, on-board chargers and charging equipment, wiring harnesses and connectors, external flammable and explosive items, etc.

[0032] The explosion risk of the above-mentioned new energy vehicles needs to be monitored to ensure the safety of new energy vehicles. In related technologies, gas monitoring devices can be placed near components with explosion risks to monitor the combustible gases and particles generated in the early stages of the explosion of the components. For example, gas monitoring devices can be placed near battery packs to monitor the combustible gases and particles generated in the early stages of the battery explosion.

[0033] Although the above method can detect abnormal gases generated in the initial combustion of corresponding components to a certain extent, it is limited by the gas types that can be monitored by the gas monitoring device. The accuracy of vehicle abnormality monitoring and processing is poor, and the timeliness of abnormal processing is poor.

[0034] To this end, for each component, abnormal gas detection can be carried out by placing gas monitoring devices at multiple points. However, considering the limited space of new energy vehicles, it is difficult to deploy multiple points for some components, and the deployment of multiple gas monitoring devices will also take up more space, increasing the cost of monitoring.

[0035] For example, battery packs are usually laid flat on the bottom of the vehicle, and the space is very limited, making it difficult to place gas monitoring devices at multiple points; a single gas monitoring device can only perform local gas monitoring within a few centimeters to more than ten centimeters around the battery pack, and cannot cover the entire battery pack or other key points that need to be monitored. In addition, due to the limitations of the types of gas monitoring, the more types of monitoring, the more complex the sensors required, and the deployment of multiple gas monitoring devices will lead to a significant increase in costs.

[0036] In order to at least partially solve the above technical problems, a vehicle abnormality handling solution combining distributed initial monitoring with centralized monitoring and analysis is proposed in this embodiment. Sampling devices are arranged at multiple sampling points inside the body of a new energy vehicle. When the arranged sampling device detects that the corresponding sampling point has an abnormality, the point gas of the sampling point is transmitted to a specific processing unit via a transmission channel to analyze the point gas, and the corresponding processing operation is specified based on the analyzed gas type. Since gas collection, problem initial screening and centralized monitoring are separated, the problem is initially screened at the sampling point by the sampling device, which can reduce the amount of gas required to be processed by the central processing monitoring device (i.e., the designated processing unit). The point gas transmitted after the initial screening of problems at different sampling points is analyzed by the central processing monitoring device, thereby improving the accuracy of abnormal monitoring and the timeliness of abnormal handling. In addition, the complexity of each point detection facility can be effectively reduced, thereby reducing the deployment cost of distributed point monitoring (i.e., the above-mentioned sampling points and monitoring points), and improving the convenience of the abnormal gas monitoring deployment location.

[0037] For new energy vehicles, multiple sampling devices can be arranged at multiple sampling points (i.e., monitoring points) inside the vehicle body, each of the multiple sampling devices is arranged at one of the multiple sampling points inside the vehicle body of the new energy vehicle, and each sampling point can be arranged with one or more sampling devices, and the multiple sampling devices are connected to the designated processing unit through the first transmission pipeline, thereby forming a structure in which the designated processing unit connects multiple sampling points. The multiple sampling devices and the designated processing unit may belong to the explosion-proof monitoring system configured for the new energy vehicle.

[0038] Here, the multiple sampling points may include sampling points corresponding to the battery packs of new energy vehicles. In addition, they may also be set in other flammable and explosive or high-risk spaces and areas (for example, fuel systems, key component compartments, and key components may be motors) to enhance the convenience of abnormal gas monitoring deployment. The sampling device may be a device for initial screening of problems at the corresponding sampling points, and may include one or more sensors, such as smoke sensors, temperature sensors, etc., so as to detect in real time whether there is combustion smoke, particles, abnormal temperature, etc. at the corresponding sampling points. The first transmission pipeline may be a closed pipeline, and the closed channel may be a one-to-many structure. The pipeline opening of the first transmission pipeline may be controlled to open and close by an electromagnetic or mechanical switch.

[0039] For example, the explosion-proof monitoring system can be divided into two parts: central processing and distributed multi-point real-time data collection. Figure 3 As shown, the unit for performing central processing is a central data detection processing unit M (an example of the above-mentioned designated processing unit), and the unit for performing distributed multi-point data real-time collection is a plurality of sampling devices [A0...A n] (initial sampling device), corresponding to the pre-set distributed monitoring points inside the body of the new energy vehicle, where n is a positive integer greater than or equal to 2. The central processing and distributed multi-point data acquisition systems are connected through a closed pipe, the opening of the closed pipe is located at the location of the monitoring point, and can be opened and closed by an electromagnetic or mechanical switch.

[0040] Optionally, the designated processing unit can obtain the gas to be analyzed transmitted by the target sampling device among multiple sampling devices. Correspondingly, the designated processing unit may include a component that converts the gas transmitted by different sampling devices into corresponding gas characteristic data (which may be called a distributed point acquisition and calculation unit) and a component that performs data processing (which may be called a central centralized domain control unit, including a vehicle control execution unit). Here, the central centralized domain control serves as a centralized computing unit and computing power unit of the entire vehicle. In the above-mentioned explosion-proof monitoring system, it is mainly used to collect and process the status monitoring signals of abnormal gases, particles, etc. uploaded by each distributed point acquisition and calculation unit and preliminarily processed.

[0041] Combination Figure 4 The data communication between the central domain control unit and the distributed point acquisition and calculation unit can be carried out through the CAN (Controller Area Network) bus or ETH (Ethernet), that is, data reporting and data interaction are carried out through the CAN bus, or data interconnection and intercommunication are carried out through Ethernet T1 (Twisted Pair 1). The above-mentioned central domain control may include a central SoC (System on a Chip) integrating a CPU (Central Processing Unit), a GPU (Graphics Processing Unit) and an NPU (Neural Processing Unit or Neural Processing Engine). While providing corresponding computing power for processing the intelligent driving domain and the intelligent cockpit domain, the SoC utilizes the multi-core and multi-process processors therein to allocate a part of the computing power for processing the data acquisition signals reported by the distributed point acquisition and calculation units.

[0042] Optionally, the central domain control unit can integrate a multi-core MCU (Microcontroller Unit or Main Control Unit) with a high functional safety level to process the algorithm of the vehicle control domain, and transmit control signals including braking and steering through the CAN bus or Ethernet bus to IBC (Integrated Braking Control), EPS (Electronic Power Steering, i.e., intelligent steering) and other body ECUs (Electronic Control Unit) for actions such as vehicle deceleration, pulling over, and assisted door opening to assist the driver and passengers in escaping the vehicle when a suspected vehicle battery explosion is detected in the early stage.

[0043] For the target sampling device among the multiple sampling devices, it can monitor the corresponding target sampling point to determine whether there is an abnormality. The abnormality here can be an air abnormality such as smoke, or a temperature abnormality. When it is determined that the target sampling point has an abnormality, the gas to be analyzed collected from the target sampling point is transmitted to the designated processing unit via the first transmission pipeline, so that the designated processing unit can make a further judgment on whether the target sampling point has an abnormality. Here, the method of transmitting the gas to be analyzed collected from the target sampling point to the designated processing unit via the first transmission pipeline can be: open the switch (electromagnetic or mechanical switch) at the pipeline opening corresponding to the first transmission pipeline and the target collection point, thereby opening the transmission channel from the target collection point to the designated processing unit; the gas to be analyzed collected through the gas collection hole at the pipeline opening corresponding to the first transmission pipeline and the target collection point is transmitted to the designated processing unit via the transmission channel from the target collection point to the designated processing unit. For the designated processing unit, it can obtain the gas to be analyzed transmitted by the target sampling device.

[0044] Optionally, the vehicle abnormality handling system may further include: an air negative pressure device configured for each sampling point or for a designated processing unit, so that the sampled gas at each sampling point can be transmitted to the designated processing unit via the first transmission pipeline through the air negative pressure, thereby increasing the speed of sampled gas transmission and reducing losses and delays during the transmission process. Correspondingly, the designated processing unit can obtain the gas to be analyzed transmitted by the target sampling device through the first transmission pipeline through the air negative pressure.

[0045] For example, when the primary sampling device (eg, A0) collects unusual gases or temperatures, the sealed pipe is opened, and part of the sampled gas is transported to the central data detection and processing unit M through the sealed pipe under negative air pressure.

[0046] Furthermore, the designated processing unit may be used to obtain a gas analysis result obtained by analyzing the gas to be analyzed, wherein the gas analysis result is used to indicate a gas type of the gas to be analyzed.

[0047] For the gas to be analyzed, the designated processing unit can use gas analysis software or algorithm to analyze it and obtain gas analysis results. The gas analysis results are used to indicate the gas type of the gas to be analyzed. Here, the gas type of the gas to be analyzed belongs to a preset group of gas types. The gas types can be divided into multiple types, as long as it can distinguish whether the corresponding sampling point has a risk of explosion. For example, a group of gas types may include types that need to be processed and types that do not need to be processed. For another example, a group of gas types may include toxic gases, ordinary exhaust gases, combustion smoke particles and high-temperature gases. For another example, a group of gas types may include level 1 risk gases to level L risk gases, where L is a positive integer greater than or equal to 2. There is no limitation on the gas type in this embodiment.

[0048] Optionally, the designated processing unit may analyze the gas to be analyzed by parsing a set of gas parameters of the gas to be analyzed, and determining the gas type of the gas to be analyzed based on parameter information of a set of gas parameters. The set of gas parameters may include but is not limited to at least one of the following: gas concentration, gas concentration growth rate, gas temperature, gas temperature growth rate, coordinated speed of gas temperature and gas concentration, concentration of particulate matter generated in different time periods, etc., and may also include other gas parameters, which are not limited to this in the present embodiment.

[0049] It should be noted that, in addition to the designated processing unit, the above-mentioned vehicle abnormality handling system may also include other processing units for analyzing the gas to be analyzed. For the scheme executed by the designated processing unit, the gas analysis result is obtained by the designated processing unit analyzing the gas to be analyzed. For the scheme executed by other processing units, the gas analysis result can be obtained by other processing units analyzing the gas to be analyzed and transmitted to the designated processing unit.

[0050] Optionally, the designated processing unit may also be configured to execute a first processing operation corresponding to the gas type of the gas to be analyzed according to a preset corresponding relationship, wherein the preset corresponding relationship is a corresponding relationship between the gas type and the processing operation.

[0051] For different gas types, corresponding processing operations can be configured, and the correspondence between the gas type and the processing operation can be a preset correspondence, which can be pre-configured and stored in a designated processing unit or a designated storage component. According to the preset correspondence, the designated processing unit can determine the processing operation corresponding to the gas type of the gas to be analyzed, that is, the first processing operation, and execute the determined first processing operation.

[0052] Here, the preset correspondence can be saved in the form of a correspondence table. The processing operations corresponding to different gas types can be the same or different. The above processing operations may include but are not limited to at least one of the following: an alarm operation for an abnormality of the sampling point, a cooling operation performed on the sampling point (for example, shutting down the power supply, air isolation, and performing a fire extinguishing action).

[0053] The vehicle abnormality handling system provided by the present application includes: a plurality of sampling devices, a first transmission pipeline and a designated processing unit; wherein each of the plurality of sampling devices is arranged at a sampling point among a plurality of sampling points inside the body of the new energy vehicle, wherein the plurality of sampling points include sampling points corresponding to the battery pack of the new energy vehicle; the first transmission pipeline is used to connect the plurality of sampling devices and the designated processing unit; the designated processing unit is used to obtain the gas to be analyzed transmitted by the target sampling device among the plurality of sampling devices; obtain the gas analysis result obtained by analyzing the gas to be analyzed; and execute the gas to be analyzed according to the preset corresponding relationship. a first processing operation corresponding to the gas type; wherein the target sampling device corresponds to a target sampling point among a plurality of sampling points, and the gas to be analyzed is a gas transmitted to the designated processing unit via the first transmission pipeline by the target sampling device when it is determined that the target sampling point corresponding to the target sampling device is abnormal; the gas analysis result is used to indicate the gas type of the gas to be analyzed; the preset corresponding relationship is the corresponding relationship between the gas type and the processing operation, which can solve the problems of poor accuracy of abnormal monitoring and poor timeliness of abnormal processing in the vehicle abnormal processing scheme of the related art, improve the timeliness of abnormal processing and the timeliness of abnormal processing, and thus improve the safety of vehicle driving.

[0054] In an exemplary embodiment, in order to prevent combustion and explosion problems, the vehicle abnormality handling system may also include: multiple nitrogen release points, a nitrogen release device and a second transmission pipeline arranged inside the body of the new energy vehicle, each nitrogen release point corresponds to a sampling point, and the multiple nitrogen release points are connected to the nitrogen release device via the second transmission pipeline, so that the nitrogen released by the nitrogen release device can be transmitted to each nitrogen release point through the second transmission pipeline, wherein the nitrogen release point corresponding to the target sampling device among the multiple nitrogen release points is the target nitrogen release point.

[0055] The nitrogen released by the nitrogen release device may be high-pressure nitrogen. For example, high-pressure nitrogen release points may be arranged in the reverse direction along the above-mentioned distributed points and their closed pipelines. When smoke, high-temperature gas, or toxic gas is detected, high-pressure nitrogen may be released locally to isolate the suspected explosion point from air contact. Optionally, the high-pressure nitrogen may be low-temperature nitrogen, which can effectively reduce the temperature of the suspected explosion point while isolating the air, slowing down or even isolating the occurrence of further combustion and explosion problems.

[0056] For example, a distributed cryogenic nitrogen release structure can be Figure 5 As shown, the central nitrogen high-pressure pump N (an example of the above-mentioned nitrogen release device) can be connected to the distributed nitrogen release points [B0...Bn], and the distributed nitrogen release points correspond one-to-one to multiple sampling devices.

[0057] Optionally, the second transmission pipeline can be nested in the first transmission pipeline. Through the above design, on the one hand, the second transmission pipeline and the first transmission pipeline can share physical space, avoiding the occupation of limited space by additional pipeline layout, and reducing the complexity of transmission pipeline layout; on the other hand, the nitrogen release point can be closely matched with the gas sampling point, ensuring that nitrogen reaches the designated area accurately and quickly, avoiding the diffusion and dilution of nitrogen during the transmission process, and avoiding the impact of nitrogen on non-abnormal areas.

[0058] For example, the cryogenic nitrogen reverse transmission channel can be nested inside the gas collection channel. When the abnormal gas detection point is laid out, the cryogenic nitrogen reverse transmission pipeline can be laid out at the same time to improve the convenience of system layout.

[0059] Optionally, the above-mentioned designated processing unit can also be used to control the nitrogen release device to transmit nitrogen to the target nitrogen release point via the second transmission pipeline when the gas to be analyzed is a gas generated by combustion, so as to cover the spatial area where the target sampling point is located with the released nitrogen.

[0060] In this embodiment, when the gas to be analyzed is a gas generated by combustion, the designated processing unit can immediately control the nitrogen release device to transmit the nitrogen released by the nitrogen release device to the target nitrogen release point, and the nitrogen released by the nitrogen release device can be transmitted via the second transmission pipeline. Here, the release amount and pressure of nitrogen can be adjusted according to the on-site conditions and preset safety standards, so as to ensure that the nitrogen can quickly cover the spatial area where the target sampling point is located, forming an effective oxygen isolation and cooling layer, further inhibiting the combustion reaction, and reducing the risk of explosion.

[0061] For example, by utilizing distributed collection paths, through the deployment of centralized high-pressure and low-temperature nitrogen and reverse distributed nitrogen release points, a closed loop of intervention in suspected explosion points for abnormal monitoring can be achieved. Reverse intervention at the early stage of monitoring suspected explosion points can help control the explosion at the early stage of abnormality, reducing the risk of vehicle damage and personal injury: early intervention at the same time as early warning of suspected explosion points can reduce the risk of vehicle spontaneous combustion and explosion spread; and the nested deployment of reverse intervention transmission channels inside the gas collection channel can effectively improve the convenience of monitoring and reverse intervention system layout.

[0062] Through this embodiment, through the deployment of centralized warm nitrogen and reverse distributed nitrogen release points and the nested layout of nitrogen transmission pipelines and sampling gas transmission pipelines, it is helpful to control the explosion in the early stage of the abnormality and reduce the risk of vehicle spontaneous combustion and the spread of explosion. At the same time, it can also avoid the occupation of limited space by additional pipeline layout and reduce the complexity of transmission pipeline layout.

[0063] In an exemplary embodiment, in order to increase the spatial area covered by the nitrogen released by the nitrogen release device, thereby more effectively isolating the combustion medium and the air, the nitrogen release end of the second transmission pipeline corresponding to each sampling point is trumpet-shaped, and a conical guide structure is provided at the outlet.

[0064] Correspondingly, the designated processing unit is further used to implement the step of controlling the nitrogen release device to transmit nitrogen to the target nitrogen release point via the second transmission pipeline by performing the following operations:

[0065] The nitrogen release device is controlled to transmit nitrogen to the target nitrogen release point via the transmission channel between the nitrogen release device and the target nitrogen release point in the second transmission pipeline, wherein the transmitted nitrogen is output in a fan-shaped or cone-shaped manner when released at the target nitrogen release point.

[0066] The second transmission pipeline may include a transmission channel between the nitrogen release device and each nitrogen release point. Similar to the first transmission pipeline, the opening and closing of the transmission channel between the nitrogen release device and different nitrogen release points can be controlled by an electromagnetic or mechanical switch. For the target nitrogen release point, the designated processing unit can control the transmission channel between the nitrogen release device and the target nitrogen release point to transmit nitrogen to the target nitrogen release point. When the nitrogen released by the nitrogen release device is released at the target nitrogen release point, it can be output in a fan shape or a cone shape.

[0067] For example, the above-mentioned distributed point nitrogen release device is placed in the central area inside the above-mentioned temperature collection cavity, and the outside is released in a trumpet shape, and a conical guide structure is placed at the outlet. Through the above-mentioned structural combination, the low-temperature nitrogen can be output in a fan-shaped / conical covering along the surface of the component to be detected when released, increasing the covered component space area and forming a local combustion medium insulation layer.

[0068] Through this embodiment, by designing the nitrogen release end of the nitrogen transmission pipeline to be trumpet-shaped and providing a conical guide structure at the outlet, the spatial area covered by the nitrogen released by the nitrogen release device can be increased, thereby more effectively isolating the combustion medium and air.

[0069] In an exemplary embodiment, in order to facilitate the layout of the sampling devices and reduce the gas flow rate inside the cavity of the first transmission pipeline, the pipeline cavity connected to each sampling point of the first transmission pipeline may include a local cavity with an increased inner diameter. Among the multiple sampling devices, the sampling device corresponding to each sampling point is arranged in the local cavity with an increased inner diameter connecting the first transmission pipeline to each sampling point.

[0070] For example, the sampling device can be a distributed point gas monitoring device, and the distributed point structure combining temperature collection and nitrogen release can be as follows: Figure 6 As shown, at each distributed point there is a cavity with an increased inner diameter (increased local cavity space), and a sampling device is placed inside to perform primary gas analysis. Due to the increase in the inner diameter, the gas flow rate inside the cavity is effectively reduced, which helps to improve the detection accuracy of trace flammable and high-temperature gases; the distributed point nitrogen release device is arranged in the central area inside the above-mentioned temperature collection cavity, and the outside is trumpet-shaped, and a conical guide structure (i.e., a guide cone) is placed at the outlet. Through the above-mentioned structural combination, the low-temperature nitrogen can be output in a fan-shaped / conical covering manner along the surface of the component to be detected when released, thereby increasing the covered component space area and forming a local combustion medium insulation layer.

[0071] For a point to be monitored, the distributed point gas monitoring device can collect distributed gas through the gas collection hole, perform primary gas analysis, and send the collected gas to the central data detection and processing unit M for further analysis when abnormalities are detected at the point to be monitored. When it is necessary to release low-temperature and high-pressure nitrogen to the point to be monitored, the nitrogen from the central nitrogen high-pressure pump N can be released in a distributed manner through the guide cone.

[0072] Through this embodiment, the first transmission pipeline may include a local cavity with an increased inner diameter, and a built-in sampling device may perform primary monitoring and analysis of abnormalities at corresponding sampling points, thereby improving the accuracy of abnormality monitoring and further enhancing the safety of vehicle operation.

[0073] In an exemplary embodiment, each sampling device may include a smoke sensor and a temperature sensor. For scenes with other monitoring requirements, each sampling device may also include other sensors. For a target sampling device, it may include a target smoke sensor and a target temperature sensor.

[0074] The target sampling device can be used to perform at least one of the following: when the target smoke sensor detects the presence of abnormal gas at the target sampling point, the transmission channel from the target sampling point in the first transmission pipeline to the designated processing unit is opened, and the gas to be analyzed is transmitted to the designated processing unit through the opened transmission channel; when the target temperature sensor detects that the temperature of the target sampling point is greater than or equal to the first temperature threshold, the transmission channel from the target sampling point in the first transmission pipeline to the designated processing unit is opened, and the gas to be analyzed is transmitted to the designated processing unit through the opened transmission channel.

[0075] In this embodiment, when the target sampling device determines that there is an abnormality in the target sampling point, it can open the transmission channel from the target sampling point in the first transmission pipeline to the designated processing unit, and transmit the gas to be analyzed to the designated processing unit through the opened transmission channel. The way in which the target sampling device opens the transmission channel from the target sampling point in the first transmission pipeline to the designated processing unit and transmits the gas to be analyzed to the designated processing unit through the opened transmission channel is similar to that in the previous embodiment, and will not be repeated here.

[0076] There may be multiple schemes for the target sampling device to determine whether there is an abnormality at the target sampling point, which may include but are not limited to at least one of the following: determining whether there is an abnormality at the target sampling point based on the target smoke sensor detecting the gas at the target sampling point; determining whether there is an abnormality at the target sampling point based on the target temperature sensor detecting the temperature at the target sampling point. Correspondingly, if the target smoke sensor detects that there is abnormal gas at the target sampling point, or the target temperature sensor detects that the temperature of the target sampling point is greater than or equal to the first temperature threshold, it can be determined that there is an abnormality at the target sampling point, and the above-mentioned operation of transmitting the gas to be analyzed can be performed at this time.

[0077] For example, a multi-point gas and temperature monitoring and collection system can be prefabricated inside the vehicle body, and the sampling devices [A0...An] prefabricated at the sampling point position can be primary air quality and temperature sampling devices. When the primary sampling device (for example, A0) collects abnormal gas or temperature, the sealed pipe is opened, and part of the sampled gas is transported to the central data detection and processing unit M through the sealed pipe through the negative air pressure for further analysis.

[0078] Through the above-mentioned new energy vehicle explosion-proof monitoring and early intervention system, the coordination of distributed detection and centralized analysis can effectively detect abnormal gases and states inside the vehicle, which helps to detect local abnormal information in advance before the vehicle explodes and issue early warnings. In addition, the combination of distributed collection and central processing effectively reduces the complexity of detection facilities at each point and greatly reduces the cost of deploying the monitoring system.

[0079] Through this embodiment, based on setting different smoke sensors and temperature sensors to monitor abnormal gases and abnormal temperatures at corresponding sampling points, abnormal monitoring of monitoring points can be performed through a variety of different types of information, thereby improving the accuracy of abnormal monitoring and enhancing the safety of vehicle operation.

[0080] In an exemplary embodiment, when the temperature sensor detects that the temperature of the corresponding sampling point exceeds a certain temperature threshold, the temperature is abnormal, and there is a high probability that a combustion point has appeared near the sampling point. If the designated processing unit is waiting to perform the corresponding processing operation after receiving the sampled gas for analysis, considering that the transmission and analysis of the sampled gas takes a certain amount of time, the combustion point may spread during this time, causing other safety risks.

[0081] In this embodiment, if the temperature sensor monitors that the temperature of the corresponding sampling point exceeds a certain temperature threshold (i.e., the temperature exceeds the abnormality), the vehicle may be stopped or partially powered off. Correspondingly, for the target sampling point, the designated processing unit or target sampling device is also used to control the new energy vehicle to perform a second processing operation when the target temperature sensor detects that the temperature of the target sampling point is greater than or equal to the second temperature threshold, wherein the second processing operation includes at least one of the following: a parking operation, and a power-off operation performed on a local circuit corresponding to the target sampling device.

[0082] When the temperature of the target sampling point reaches or exceeds the second temperature threshold, the designated processing unit or other processing units of the new energy vehicle can quickly make a judgment and control the new energy vehicle to perform the second processing operation. The second processing operation can help reduce the risk of explosion at the target sampling point and can also help improve the safety of the people in the vehicle. Optionally, the second processing operation may include at least one of the following: a parking operation, which can immediately send an instruction to the vehicle control unit to force a safe parking operation. The new energy vehicle can choose the safest way to slow down and finally stop according to the current driving state and environment, including but not limited to using the emergency braking system, adjusting the energy recovery intensity, etc., to avoid vehicle loss of control or accidents caused by excessive temperature; a power-off operation performed on the local circuit corresponding to the target sampling device, which can send a power-off instruction to the local circuit (e.g., BMS) corresponding to the target sampling device through the CAN bus or Ethernet bus to cut off the power supply to the circuits and components that may cause the temperature to further increase, thereby reducing the risk of vehicle overheating and runaway.

[0083] Optionally, the target sampling device may directly control the new energy vehicle to perform the second processing operation when detecting that the temperature of the target sampling point is greater than or equal to the second temperature threshold.

[0084] Optionally, the above-mentioned parking operation and power-off operation can be performed simultaneously to further ensure safety. The second temperature threshold can be set by the manufacturer based on the thermal management standards of the battery pack and the vehicle's electronic equipment and a comprehensive consideration of other key vehicle components that may fail due to high temperature, and can also be adjusted according to the driver's needs. The second temperature threshold can also be obtained by fitting the temperature of the corresponding sampling position when a combustion and explosion accident occurs in a vehicle of the same model. For different sampling positions, the corresponding overheating temperature (i.e., the temperature threshold that triggers the execution of the second processing operation) can be the same or different.

[0085] For example, a designated processing unit or sampling device can monitor the temperature of a sampling point in real time. If the temperature of the sampling point is detected to be abnormal, that is, exceeds a set temperature threshold, it is determined to be abnormally high temperature, and the vehicle is stopped, a partial power outage, or the like is performed.

[0086] Through this embodiment, when the temperature of the sampling point is monitored to exceed the abnormal level, the abnormal processing delay caused by the transmission and analysis of the sampled gas can be reduced by executing processing such as parking and local power outage, thereby effectively preventing possible combustion and explosion accidents and improving the safety of occupants and vehicles.

[0087] In an exemplary embodiment, each sampling device may include multiple air inlets, and the multiple air inlets may be distributed in multiple positions of the corresponding sampling device so as to collect gas from different directions of the corresponding sampling points. Multiple air inlets can increase the gas flow rate, ensure that the gas used by the sampling device for primary screening or the point temperature monitored is consistent with the actual gas (e.g., gas concentration, particulate matter concentration, etc.) and temperature at the sampling point, as well as the efficiency of the primary screening, thereby improving the accuracy and timeliness of the sampling point monitoring. Correspondingly, for the target sampling point, each sampling device is also used to control the air volume flowing into the multiple air inlets of each sampling device, so as to deliver the gas in the spatial area where the sampling point corresponding to each sampling device is located into the pipe cavity connected to the first transmission pipe and the sampling point corresponding to each sampling device.

[0088] In this embodiment, each sampling device can be used to control the air volume flowing into multiple air inlets of the sampling device. For example, the above-mentioned vehicle abnormality handling system may include a set of intelligent air volume control systems. The air volume control system can automatically adjust the air volume flowing into multiple air inlets of the target sampling device according to environmental conditions and sampling requirements, thereby ensuring that the gas in the spatial area where the target sampling point is located can be delivered into the pipe cavity connecting the first transmission pipe and the target sampling point, thereby improving the accuracy and efficiency of gas collection.

[0089] Optionally, each air inlet of each sampling device may include an adjustable air volume valve, and the designated processing unit or other processing unit may control the adjustable air volume valve to automatically adjust the opening of the adjustable air volume valve, thereby adjusting the air volume entering the pipeline cavity. In order to monitor the amount of gas entering the pipeline cavity, a wind speed sensor may be installed near the air inlet or in the pipeline cavity to monitor the air volume in real time and feed it back to the designated processing unit or other processing unit, so that it can adjust the control strategy in time according to the actual monitored value of the air volume.

[0090] For example, a distributed point gas collection device may include multiple air inlets, and by controlling the air flow rate, it can effectively cover the local area space.

[0091] Through this embodiment, by providing a plurality of air inlets in each sampling device and controlling the air volume of the air inlets, the accuracy of gas collection can be improved, thereby improving the accuracy of abnormal gas detection.

[0092] In an exemplary embodiment, the designated processing unit is further configured to implement the step of performing a first processing operation corresponding to the gas type of the gas to be analyzed by the designated processing unit according to the preset corresponding relationship by performing the following operations:

[0093] In the case where the gas to be analyzed is a gas generated by combustion, a power-off operation is performed on a local circuit corresponding to the target sampling device by a designated processing unit;

[0094] In the case that the gas to be analyzed is not a gas generated by combustion, the designated processing unit performs an abnormality prompt operation to prompt that the new energy vehicle has an abnormality.

[0095] In this embodiment, a group of gas types may include gases generated by combustion and gases not generated by combustion, or a group of gas types may include gas types that can distinguish whether they are gases generated by combustion, such as the above-mentioned toxic gases, ordinary exhaust gas, combustion smoke particles, and high-temperature gases. Different processing operations may be used for gases generated by combustion and gases not generated by combustion.

[0096] Optionally, if the gas to be analyzed is a gas generated by combustion, the designated processing unit may perform a power-off operation on the local circuit corresponding to the target sampling device. In this case, the first processing operation includes a power-off operation performed on the local circuit. Here, the local circuit corresponding to each sampling device may be pre-configured, and the local circuits corresponding to different sampling devices may be at least partially different. The power-off operation instruction may be quickly transmitted to the vehicle's battery management system or other related circuit control units via a CAN bus or an Ethernet bus to ensure that the power supply is cut off in the shortest possible time.

[0097] For example, the central data detection processing unit M further analyzes the current gas state in detail, whether it is toxic gas, ordinary exhaust gas, or combustion smoke particles, etc. If it is analyzed to be gas produced by combustion, it is considered that there is combustion or other risk problems at the current sampling point location, and the power supply to the circuit in this area is cut off to cut off potential fire sources and prevent the spread of combustion. If conditions permit, cooling actions can also be performed (for example, turning off power supply, air isolation, or performing fire extinguishing actions, etc.).

[0098] Optionally, if the gas to be analyzed is not generated by combustion, the designated processing unit may perform an abnormality prompt operation to prompt that the new energy vehicle has an abnormality. In this case, the first processing operation includes an abnormality prompt operation. Here, the prompt performed by the abnormality prompt operation may be at least one of an abnormality prompt and a parking prompt for the driver and / or passenger of the new energy vehicle, or a return to factory inspection prompt for the driver of the new energy vehicle, or other prompts, which are not limited in this embodiment.

[0099] For example, if the analysis shows that the gas is ordinary pollutant, an alarm message will be reported to prompt the vehicle to stop, or an early warning will be issued in the background to prompt the driver to return to the factory for inspection.

[0100] Optionally, the first processing operation may also include other operations to reduce the health risks of occupants of the vehicle, increase the service life of the vehicle, etc. The other operations may include but are not limited to at least one of the following: starting the vehicle ventilation system, adjusting the vehicle operating mode, etc.

[0101] Through this embodiment, by performing different processing operations on the gas generated by combustion and the gas not generated by combustion, the potential safety hazard of new energy vehicles can be reduced and the safety of operation of new energy vehicles can be improved.

[0102] In an exemplary embodiment, the designated processing unit is further configured to implement the step of obtaining a gas analysis result obtained by analyzing the gas to be analyzed by performing the following operations:

[0103] Analyze the gas to be analyzed to obtain gas characteristics of the gas to be analyzed, wherein the gas characteristics include at least one of the following: the concentration increase rate of the gas to be analyzed, and the concentration of particulate matter contained in the gas to be analyzed in different time periods;

[0104] Analyze the gas type of the gas to be analyzed based on the characteristics of the gas to be analyzed to obtain a gas analysis result; or,

[0105] The characteristics of the gas to be analyzed are uploaded to the server, and the server receives the gas analysis results obtained by analyzing the gas type of the gas to be analyzed.

[0106] In this embodiment, in order to facilitate the identification of the gas type of the gas to be analyzed, the designated processing unit can be used to perform in-depth analysis on the gas to be analyzed and obtain the gas characteristics of the gas to be analyzed, that is, the gas characteristics to be analyzed, which may include but are not limited to at least one of the following: the concentration increase rate of the gas to be analyzed, the concentration of particulate matter contained in the gas to be analyzed in different time periods. In addition, in order to improve the accuracy of gas type determination, in addition to the above-mentioned gas characteristics, gaseous gas characteristics can also be obtained, such as the temperature increase rate of the gas, the coordinated rate of the temperature and concentration of the gas, etc.

[0107] Based on the characteristics of the gas to be analyzed, the designated processing unit can be used to analyze the gas type of the gas to be analyzed using a gas analysis algorithm to obtain a gas analysis result. The analysis of the gas type of the gas to be analyzed can be performed by the designated processing unit, and correspondingly, the designated processing unit can analyze the gas type of the gas to be analyzed based on the characteristics of the gas to be analyzed to obtain a gas analysis result. Optionally, in order to improve the accuracy of monitoring and reduce the probability of false alarms, the analysis of the gas type of the gas to be analyzed can also be performed by the cloud, and correspondingly, the designated processing unit uploads the characteristics of the gas to be analyzed to a server (for example, a cloud server), and the server analyzes the gas type of the gas to be analyzed based on the received characteristics of the gas to be analyzed, and sends the obtained gas analysis result to the designated processing unit. The designated processing unit can receive the above-mentioned gas analysis result sent by the server,

[0108] Optionally, the designated processing unit can also be used to first analyze the characteristics of the gas to be analyzed and determine the gas type of the gas to be analyzed. If the gas type of the gas to be analyzed is a designated gas type (for example, a gas type generated by combustion), the characteristics of the gas to be analyzed are uploaded to the server, and the server further refines the gas type of the gas to be analyzed, and then sends the gas analysis results to the designated processor to improve the accuracy of monitoring and reduce the probability of false alarms. Here, the server has stronger computing power and rich database resources, and can perform deeper analysis and processing of data.

[0109] For example, the central domain control can use its own computing power and algorithm fitting to infer whether it is currently in a combustion state or is only caused by abnormal gases in the external environment based on the gas characteristics of abnormal gases collected at each monitoring point, and make refined judgments and identification. In addition, the above calculation results (for example, the characteristic values ​​of the collected sample data) can be uploaded to the cloud server through the on-board communication unit, and refined analysis can be performed using background big data analysis and further algorithm fitting to improve the accuracy of monitoring and reduce the probability of false alarms. The on-board communication unit can be a built-in 5G (5th Generation, fifth-generation mobile communication technology) communication module. Here, the detailed analysis of the central processing monitoring device and the further calculation and processing of the sampled data by the cloud background server will help improve the accuracy of detection and reduce the occurrence of false alarms.

[0110] Through this embodiment, the sampled gas is analyzed to obtain data that can be processed by the computing unit (i.e., gas characteristic information), and the processing unit and / or cloud server on the new energy vehicle analyzes the gas characteristics to determine the gas type of the sampled gas. This can improve the flexibility and accuracy of gas type determination, thereby effectively preventing and controlling the occurrence of combustion and explosion accidents.

[0111] In an exemplary embodiment, the characteristics of the gas to be analyzed include a concentration increase rate of the gas to be analyzed and a concentration of particulate matter contained in the gas to be analyzed in different time periods.

[0112] Correspondingly, the designated processing unit is further used to implement the step of analyzing the gas type of the gas to be analyzed based on the characteristics of the gas to be analyzed by the designated processing unit to obtain the gas analysis result by performing the following operations:

[0113] The gas type of the gas to be analyzed is analyzed based on the concentration increase rate of the gas to be analyzed, the concentration of particulate matter contained in the gas to be analyzed in different time periods, the point temperature of the target sampling point and the temperature increase rate of the target sampling point to obtain the gas analysis result.

[0114] In this embodiment, in the case where the sampling device includes a temperature sensor, the gas characteristics used to analyze the gas type of the gas to be analyzed may include: the rate of increase in gas concentration, the concentration of particulate matter contained in the gas in different time periods, the point temperature, and the rate of increase in the point temperature. For the gas to be analyzed, the gas type of the gas to be analyzed can be analyzed based on the rate of increase in concentration of the gas to be analyzed, the concentration of particulate matter contained in the gas to be analyzed in different time periods, the point temperature of the target sampling point, and the rate of increase in temperature of the target sampling point to obtain a gas analysis result. The above operations can be performed by a designated processing unit or by a server.

[0115] For example, the central domain control can use its own computing power and algorithm fitting to infer whether it is currently in a combustion state or is only caused by abnormal gases in the external environment based on the concentration increase rate of abnormal gases collected at each monitoring point, the temperature coordination rate, the concentration of particulate matter generated in different time periods, etc., and make refined judgments and identification.

[0116] Through this embodiment, gas characteristic data and temperature data can be integrated to perform gas analysis, thereby improving the accuracy and reliability of abnormal gas analysis.

[0117] It should be noted that the above modules can be implemented by software or hardware. For the latter, it can be implemented in the following ways, but not limited to: the above modules are all located in the same processor; or the above modules are located in different processors in any combination.
