Technical Field
[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a disaster prevention control method, device and storage medium for new energy vehicles. Background Art
[0002] New energy heavy-duty trucks are different from fuel heavy-duty trucks. Customers need to start the engine when using the vehicle power interface, otherwise the vehicle battery will be depleted due to long-term use. New energy heavy-duty trucks are convenient to use. When the vehicle is not on high voltage, users can use the 24V power converted by the power battery to power external devices. Therefore, customers of new energy heavy-duty trucks will use electricity more frequently, but the increase in the frequency of power use will also bring certain power risks. New energy heavy-duty trucks are designed with a backup power interface in the cab. Users can purchase the corresponding equipment online to plug in and draw power. However, the quality of the power interfaces of electrical equipment on the market varies. When the interface of the electrical equipment is connected to the backup power supply of the vehicle to draw power, there is a risk of false connection. False connection will cause the contact position to heat up and then create the risk of fire. Failure to prevent it in time will cause greater safety risks and property losses.
[0003] Therefore, there is an urgent need for a new energy vehicle disaster prevention control method, device and storage medium to solve the above technical problems. Summary of the Invention
[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a disaster prevention control method, device and storage medium for new energy vehicles, which can solve the technical problem that the contact position is heated due to the loose connection between the interface of the electrical equipment and the backup power supply of the whole vehicle, thereby causing the risk of fire and the inability to prevent it in time, leading to the expansion of the danger.
[0005] To achieve the above object, the present invention is implemented by adopting the following technical solutions: In a first aspect, the present invention provides a new energy vehicle disaster prevention control method, comprising: Obtaining the positive electrode temperature of the thermocouple and the ambient temperature in the vehicle cab, and calculating the standby power supply temperature based on the positive electrode temperature of the thermocouple and the ambient temperature in the vehicle cab; When the temperature of the backup power supply reaches a preset safety temperature and the duration exceeds a preset safety working time, the control relay is disconnected; When the temperature of the backup power source reaches a preset safety temperature and the duration exceeds a preset alarm lead time, the surround view controller is controlled to identify a fire source in the cab. When the surround view controller identifies the fire source, the door and window motors are controlled to lower the doors and windows while the door lock motors are controlled to unlock the doors. The thermocouple is connected to the negative pole harness core wire of the backup power supply through a heat shrink tube.
[0006] Furthermore, calculating the standby power supply temperature according to the positive electrode temperature of the thermocouple and the ambient temperature in the vehicle cab includes: Backup power supply temperature = positive pole temperature of thermocouple * k - ambient temperature in vehicle cab, Wherein, k is the preset temperature proportional coefficient.
[0007] Furthermore, it also includes: a fuse connected in series with the relay, which is used to blow out the circuit when the current flowing through the fuse exceeds the rated value of the fuse and maintains the blowing time.
[0008] Furthermore, it also includes: When the temperature rise rate of the backup power supply in unit time is greater than n times the preset normal temperature rise rate, the control relay K1 is disconnected and the power supply of the backup power supply is cut off.
[0009] In a second aspect, the present invention provides a disaster prevention control device for a new energy vehicle, comprising: A temperature acquisition module is used to obtain the positive electrode temperature of the thermocouple and the ambient temperature in the vehicle cab, and calculate the standby power supply temperature based on the positive electrode temperature of the thermocouple and the ambient temperature in the vehicle cab; A main control module is used to control the relay to disconnect when the temperature of the backup power supply reaches a preset safety temperature and the duration exceeds a preset safety working time; The door control module is used to control the surround view controller to identify the fire source in the cab when the temperature of the backup power supply reaches a preset safety temperature and the duration exceeds the preset alarm lead time. When the surround view controller identifies the fire source, it controls the door and window motor to lower the door and window while controlling the door lock motor to open the door lock.
[0010] Furthermore, the main control module also includes: When the temperature rise rate of the backup power supply in unit time is greater than n times the preset normal temperature rise rate, the control relay K1 is disconnected and the power supply of the backup power supply is cut off.
[0011] In a third aspect, the present invention provides an electronic terminal comprising a processor and a memory connected to the processor, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the steps of any of the above methods are performed.
[0012] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, which implements the steps of any of the above methods when executed by a processor.
[0013] Compared with the prior art, the present invention has the following beneficial effects: The application first provides a new energy vehicle disaster prevention control method, which calculates the backup power supply temperature according to the collected positive electrode temperature of the thermocouple and the environmental temperature in the cab of the whole vehicle, and then judges whether to disconnect the relay, control the door and window motor and control the door lock motor according to the backup temperature, so as to realize the temperature monitoring of the contact position caused by the false connection of the interface of the electric equipment and the backup power supply of the whole vehicle, prevent the fire and prevent the further expansion of the fire danger. Since the direct installation of the temperature measuring element at the backup power supply will affect the subsequent installation of the whole vehicle, the thermocouple is connected to the negative pole wire harness core wire of the backup power supply through the heat shrink tube, and then the positive electrode temperature of the thermocouple and the environmental temperature in the cab of the whole vehicle are collected to calculate the backup power supply temperature, so that the backup power supply temperature can be measured without affecting the normal use of the new energy vehicle. The two cutting-off modes of continuous high temperature and too fast temperature rise speed improve the rapidity and comprehensiveness of identifying faults, and timely control of the vehicle window and the vehicle door provides convenience for the driver to escape.

In the case of no conflict, the technical features in the embodiments and the embodiments can be combined with each other.

The method of the present embodiment specifically includes the following steps: Step one: Figure 1 is a flowchart of the new energy vehicle disaster prevention control method in embodiment one of the present application. The flowchart only shows the logical order of the method described in the present embodiment, and under the premise of not conflicting with each other, the steps shown or described can be completed in an order different from that shown in other possible embodiments of the present application. Figure 1
[0019] The new energy vehicle disaster prevention control method provided in the present embodiment can be applied to a terminal and can be executed by a mechanical equipment fault identification device. The device can be realized by software and / or hardware, and the device can be integrated in the terminal, such as any smart phone, tablet computer or computer device with communication function. The method of the present embodiment specifically includes the following steps: Step one: obtaining the positive temperature of the thermocouple 9 and the environmental temperature in the cab of the whole vehicle, and calculating the temperature of the backup power supply 8 according to the positive temperature of the thermocouple 9 and the environmental temperature in the cab of the whole vehicle; The thermocouple 9 is connected to the negative wire harness core wire of the backup power supply 8 through the heat shrink tube 901. The installation position of the thermocouple 9 will be described here. Since the thermocouple 9 is directly installed on the backup power supply 8 to measure the temperature, it will affect the subsequent installation of the whole vehicle. Therefore, the thermocouple 9 of the present application is connected to the negative wire harness core wire of the backup power supply 8 through the heat shrink tube 901 to realize the temperature measurement of the backup power supply 8, as shown in Figure 3
[0020] Step 2: When the temperature of the backup power supply 8 reaches a preset safety temperature (in this embodiment, the safety temperature is 95 degrees) and the duration exceeds a preset safety working time (in this embodiment, the safety working time is 10 seconds), the control relay is disconnected; Specifically, according to the positive electrode temperature of the thermocouple 9 and the ambient temperature in the vehicle cab, calculating the temperature of the backup power supply 8 includes: The temperature of the backup power supply 8 = the positive pole temperature of the thermocouple 9 * k - the ambient temperature in the vehicle cab, Wherein, k is a preset temperature proportional coefficient. Different backup power supplies 8 and different thermocouples 9 may change the temperature proportional coefficient. Figure 5 As shown (the horizontal axis unit is time, the vertical axis unit is temperature), the proportional coefficient provided in this application is 2, which is used to compensate for the temperature of the backup power supply 8 measured at the thermocouple 9.
[0021] In addition, when the temperature rise rate of the backup power supply 8 per unit time is greater than n times the normal temperature rise rate of the preset value (i.e., the additional Figure 3 The temperature rise rate in the circuit is too fast), the control relay K1 is disconnected, and the power supply of the backup power supply 8 is cut off.
[0022] Step 3: When the temperature of the backup power supply 8 reaches a preset safety temperature and the duration exceeds the preset alarm lead time (60 seconds in this embodiment), the surround view controller 3 is controlled to identify the fire source in the cab. When the surround view controller 3 identifies the fire source, the door and window motor 7 is controlled to lower the door and window while controlling the door lock motor 6 to open the door lock.
[0023] In addition, it also includes: a fuse connected in series with the relay (i.e., attached Figure 2 FU1 in the figure) is used to disconnect the circuit when the current flowing through the fuse exceeds the rated value of the fuse and maintains the melting time (the melting time is related to the properties of the fuse itself. The fuse belongs to the existing technology and will not be described in detail here). Example 2:
[0024] The second embodiment of the present invention provides a new energy vehicle disaster prevention control device, such as Figure 2 Shown, including: The temperature acquisition module is used to obtain the positive electrode temperature of the thermocouple 9 and the ambient temperature in the vehicle cab, and calculate the temperature of the backup power supply 8 according to the positive electrode temperature of the thermocouple 9 and the ambient temperature in the vehicle cab; A main control module is used to control the relay to disconnect when the temperature of the backup power supply 8 reaches a preset safety temperature and the duration exceeds a preset safe working time; The door control module 2 is used to control the surround view controller 3 to identify the fire source in the cab when the temperature of the backup power supply 8 reaches a preset safety temperature and the duration exceeds the preset alarm lead time.

[0025] It also includes an output module for controlling the relay to disconnect when the main control module outputs a disconnect signal. The temperature acquisition module, the main control module and the output module together constitute the power controller 1.
[0026] Specifically, the main control module also includes: When the temperature rise rate of the backup power supply 8 per unit time is greater than n times the preset normal temperature rise rate, the control relay K1 is disconnected and the power supply of the backup power supply 8 is cut off.
