The automatic fire extinguishing method for automobiles according to claim 2, wherein after the step of judging whether there is an abnormal line on the target automobile according to the response information, the method further comprises: When judging that the abnormal line does not exist on the target vehicle, photographing the engine compartment to obtain the current image; Perform image recognition on the current image to obtain image features, and determine whether the image features match the flame features; When it is determined that the image characteristics match the flame characteristics, the heater in the gas generator is controlled to heat the inflating agent, so that the inflating agent is reacted with sodium nitride to generate nitrogen gas. 5. The automatic fire extinguishing method for automobiles as claimed in claim 2, wherein the method further comprises: When it is determined that the current temperature is less than or equal to the temperature threshold and the abnormal line exists on the target vehicle, a prompt alarm is issued for the abnormal line. 6 . The automatic fire extinguishing method for automobiles according to claim 1 , wherein after the step of controlling the fire extinguishing agent in the fire extinguishing agent storage chamber to diffuse to the engine compartment under the pressure of the nitrogen, the The method also includes: Real-time acquisition of temperature and state images of the engine compartment, fire extinguishing feedback information, and local pre-stored communication address; The fire extinguishing feedback information is sent to the communication address according to a preset time interval. 7. An automatic fire extinguishing system for automobiles, wherein the system comprises: an information acquisition module for acquiring the temperature information of the engine compartment in the target vehicle, and acquiring the line information of the target vehicle; A fire extinguishing judgment module, used to judge whether the temperature information and the line information both meet the fire extinguishing conditions; A heating control module, configured to control the heater in the gas generator in the engine compartment to heat the inflating agent when it is determined that the temperature information and the line information both meet the fire extinguishing conditions, so that the inflatable The sodium nitride reaction is carried out in the agent to generate nitrogen gas; A fire extinguishing channel control module for judging whether the current air pressure of the gas generator is greater than the air pressure threshold, and when judging that the current air pressure is greater than the air pressure threshold, open the channel between the gas generator and the fire extinguishing agent storage chamber , so that the nitrogen gas is charged into the fire extinguishing agent storage chamber; A fire-extinguishing execution module is used to control the fire-extinguishing agent in the fire-extinguishing agent storage chamber to diffuse into the engine compartment under the ramming of the nitrogen gas, so as to extinguish the fire-extinguishing of the engine compartment. 8. The automatic fire-extinguishing system for automobiles as claimed in claim 7, wherein the fire-extinguishing judgment module is also used for: Obtain the current temperature stored in the temperature information, and determine whether the current temperature is greater than a temperature threshold; When it is determined that the current temperature is greater than the temperature threshold, acquiring the response information stored in the line information, and determining whether there is an abnormal line on the target vehicle according to the response information; When it is determined that the abnormal line exists on the target vehicle, it is determined that both the temperature information and the line information satisfy the fire extinguishing condition. 9. A mobile terminal, characterized in that it comprises a storage device and a processor, wherein the storage device is used to store a computer program, and the processor runs the computer program to cause the mobile terminal to execute according to claims 1 to 6 Any one of the automatic fire extinguishing methods for automobiles. 10. A storage medium, characterized in that it stores a computer program used in the mobile terminal according to claim 9, and when the computer program is executed by a processor, realizes the automobile according to any one of claims 1 to 6 The steps of the automatic fire extinguishing method.
