Therefore, it is necessary to check the automobile at regular time to find out a problem in time. Or, the terminal is used for early warning the possible safety problems, so as to remind the user to check the automobile.

Aiming at the application scene, the embodiment of the application provides an application program of automobile safety pre-warning. Through the application program, the state of the automobile can be monitored in real time, and early warning is carried out when the automobile possibly has a safety problem. Through the application program, the service time of a plurality of devices of the automobile can be monitored, and early warning is carried out when the service time exceeds the upper limit of the service time. Through the application program, the user can actively check the state of the automobile, the use time of each device of the automobile and the like.

The embodiment of the application provides a method for early warning of automobile safety, which is used for early warning when an engine of an automobile has a problem. The process flow of the method can be as shown in fig. 4, and comprises the following processing steps:

401, the vehicle-mounted terminal acquires the air pressure parameter value of the air cylinder of the engine according to a preset period, and determines the working state of the air cylinder.

The working state is an air inlet state, an air outlet state or a stop state.

In practice, the engine is used as the main device for powering the car, and the safety problem is related to the safety of the car. Therefore, whether the automobile is in a safe state can be judged through the real-time working condition of the engine. The cylinder is an important part of the engine, and other parts of the engine are problematic and can affect the operation of the cylinder. Therefore, whether the engine is working normally or not can be judged through the real-time air pressure parameter value of the air cylinder.

The air pressure sensor of the automobile can transmit the detected air pressure parameter value of the air cylinder to the vehicle-mounted terminal according to a preset period. The vehicle-mounted terminal can acquire the working state of the air cylinder when receiving one air pressure parameter value. And determining whether the automobile is in a safe state or not by the vehicle-mounted terminal through the air pressure parameter value of the air cylinder and the working state of the air cylinder.

And 402, the vehicle-mounted terminal determines a plurality of air pressure ranges corresponding to the working state and determines the air pressure range to which the air pressure parameter value belongs. If the air pressure range determined by the in-vehicle terminal is the second range, step 403 is performed. If the air pressure range determined by the in-vehicle terminal is the third range, step 404 is performed.

The plurality of air pressure ranges comprise a first range, a second range and a third range, wherein the first range is used for indicating that the air cylinder is in a safe working state, the second range is used for indicating that the air cylinder is in a normal working state but needs maintenance, and the third range is used for indicating that the air cylinder is in a dangerous working state.

In practice, each operating state corresponds to three air pressure ranges, for example, table 1 shows the correspondence between operating states and air pressure ranges. After the working state of the air cylinder is determined by the vehicle-mounted terminal, a plurality of air pressure ranges corresponding to the working state of the air cylinder are determined based on the corresponding relation between the working state and the air pressure ranges. Further, an air pressure range to which the air pressure parameter value belongs is determined.

TABLE 1

Operating state	First range	Second range	Third range
				Intake state	10-20	5-9、21-25	<5、>25
State of air outlet	15-20	5-14、21-25	<5、>25
				Stop state	0-1	2-10	>10

If the air pressure range determined by the vehicle-mounted terminal is the first range, the air cylinder is in a safe working state, and safety early warning is not needed for the automobile. If the vehicle terminal determines that the air pressure range is the second range, it indicates that the cylinder needs maintenance, and step 403 may be performed. If the air pressure range determined by the vehicle-mounted terminal is the third range, it indicates that the air cylinder is in a dangerous working state, and the user needs to immediately stop driving the vehicle, so that step 404 may be performed.

Additionally, the barometric pressure parameter value may be marked based on the determined barometric pressure range. For example, if the determined barometric pressure range is the first range, the corresponding barometric pressure parameter value may be marked as safe. If the determined barometric pressure range is the second range, the corresponding barometric pressure parameter value may be marked as requiring maintenance. If the determined barometric pressure range is a third range, the corresponding barometric pressure parameter value may be marked as dangerous. Thus, when the user views the air pressure parameter value of the air cylinder, the vehicle-mounted terminal or the mobile terminal can display the air pressure parameter value as a corresponding color based on the mark of the air pressure parameter value. For example, if the flag of the air pressure parameter value is safe, the air pressure parameter value may be displayed as green, or an indicator lamp corresponding to the operation state of the air cylinder may be displayed as green. If the marking of the air pressure parameter value is that maintenance is required, the air pressure parameter value may be displayed in yellow, or an indicator lamp corresponding to the operating state of the cylinder may be displayed in yellow. If the marking of the air pressure parameter value is dangerous, the air pressure parameter value may be displayed in red, or an indicator lamp corresponding to the operating state of the air cylinder may be displayed in red.

The user may actively view the operating state of the cylinder of the target vehicle, the air pressure parameter value, etc., and the relevant display interface of the application program may be as shown in fig. 5. The display interface may display information about the engine of the target vehicle, such as the model number of the engine, the start-up time, the upper limit of the use period, and the like. The user can see the real-time air pressure parameter value of the air cylinder, the corresponding working state and the air pressure range in the interface. In addition, the user can click on the control of the equipment information interface to view the related information of each equipment of the automobile, and can click on the control of the personal interface to view the related information of the user and the target automobile, such as the automobile type, the frame number, the maintenance time and the like of the target automobile.

In implementation, when the target vehicle is in a starting state, safety early warning can be performed through the vehicle-mounted terminal, namely, the vehicle-mounted terminal displays first early warning prompt information to prompt a user to repair and maintain the engine. When the target vehicle is not in a starting state, safety early warning can be carried out through the mobile terminal, namely the mobile terminal displays first early warning prompt information to prompt a user to repair and maintain the engine. The display interface may be as shown in fig. 6.

The user can click the closing control in the related display interface, after detecting the operation of clicking the closing control by the user, the vehicle-mounted terminal or the mobile terminal closes the display of the first early warning prompt information, and after the preset time length, the first early warning prompt information is displayed again. The user can click a control for reminding in time in the related display interface, after detecting the operation of clicking the control by the user, the vehicle-mounted terminal or the mobile terminal closes the popup window display of the first early warning prompt information and jumps to the reminding time setting interface, and the user can set the reminds time of the first early warning prompt information in the interface.

404, when the target vehicle is in a starting state, the vehicle-mounted terminal displays the second early warning prompt information and carries out voice broadcasting on the second early warning prompt information, and when the target vehicle is not in the starting state, the vehicle-mounted terminal sends the second early warning prompt information to the mobile terminal so that the mobile terminal displays the second early warning prompt information.

The second early warning prompt information is used for prompting a user to stop driving the target vehicle.

In implementation, when the target vehicle is in a starting state, the safety early warning can be performed through the vehicle-mounted terminal, namely, the vehicle-mounted terminal displays second early warning prompt information and performs voice broadcasting to prompt the user to stop driving the target vehicle. When the target vehicle is not in a starting state, safety early warning can be carried out through the mobile terminal, namely the mobile terminal displays second early warning prompt information and carries out voice broadcasting, so that a user is prompted to stop driving the target vehicle. The display interface may be as shown in fig. 7. The air pressure parameter value of the air cylinder is in the third range, so that when the target vehicle is in a starting state, a closing control is not arranged in the display interface, and continuous safety early warning is carried out on a user. And stopping displaying the second early warning prompt information when the vehicle-mounted terminal detects that the target vehicle is in the driving stopping state. When the target vehicle is not in a starting state, a closing control and a timing reminding control can be set in the display interface.

The embodiment of the application provides a method for monitoring whether an engine is stolen or not in the process of overhauling the engine. The process flow of the method can be as shown in fig. 8, and comprises the following processing steps:

801, when detecting the clicking operation of the user on the overhaul control, the vehicle-mounted terminal or the mobile terminal sends an overhaul notification to the server.

The overhaul notification is used for prompting the server to monitor the position of the engine.

In implementation, when a user places a target vehicle in a vehicle repair factory to repair an engine, an associated application program of the vehicle-mounted terminal or the mobile terminal can be opened, and a repair control corresponding to the engine is clicked in an associated display interface (for example, fig. 5) of the application program. And after the vehicle-mounted terminal or the mobile terminal detects the clicking operation of the user on the overhaul control, sending an overhaul notification to the server. The overhaul notification can carry the position information of the automobile repair factory, the identification of the engine, the vehicle identification of the target vehicle, the user identification and the like.

The server acquires the position of the engine and the position of the target vehicle at a preset period and determines whether the distance between the position of the engine and the position of the target vehicle is within a specified range 802. And if the distance between the position of the engine and the position of the target vehicle is not in the specified range, sending third early warning prompt information to the mobile terminal.

The third early warning prompt information is used for prompting a user to determine whether the engine is stolen or not.

In practice, the engine may have a positioning chip mounted thereon. After receiving the overhaul notification, the server determines the position of the engine and the position of the target vehicle, calculates the distance between the two positions, and further determines whether the distance is within a specified range. If within the specified range, it is indicated that the engine is still on the target vehicle. If the engine is not in the specified range, the engine is possibly not on the target vehicle, namely the engine is possibly stolen, and at the moment, the server can send a third early warning prompt message to the mobile terminal to remind a user to determine whether the engine is stolen or not. In addition, the server may also determine a distance between the location of the engine and the location of the repair facility and determine whether the distance is within a specified range. If the engine is within the specified range, the engine is indicated as being in a repair shop. If the engine is not in the specified range, the engine is possibly not in the automobile repair factory, namely the engine is possibly stolen, and at the moment, the server can also send a third early warning prompt message to the mobile terminal.

803, the mobile terminal displays the third early warning prompt information and performs voice broadcasting.

The embodiment of the application provides a method for determining whether the engine model is correct or not after the engine is replaced. The process flow of the method can be as shown in fig. 9, and comprises the following processing steps:

The replacement notification may carry a target model of the engine, a vehicle identifier of the target vehicle, a user identifier, and the like.

In implementation, when the user needs to replace the engine of the target vehicle, an application program related to the vehicle-mounted terminal or the mobile terminal can be opened, and a corresponding replacement control of the engine is clicked in a related display interface (for example, fig. 8) of the application program. And after the vehicle-mounted terminal or the mobile terminal detects the clicking operation of the user on the overhaul control, sending a replacement notification to the server.

And 902, the mobile terminal acquires the model of the replaced engine through graphic code scanning and sends the model to a server.

In implementations, after replacing the engine, the user can click on the scan code control in the relevant page of the application. After detecting the clicking operation of the user, the mobile terminal scans the graphic code pasted on the engine. And acquiring related information of the replaced engine by scanning the graphic code, wherein the related information comprises the model number, the replacement date, the upper limit of the using time and the like of the engine. And the mobile terminal sends the acquired related information of the replaced engine to a server and displays the information.

903, the server determines whether the model of the replaced engine is the same as the target model, and if the model of the replaced engine is different from the target model, sends fourth early warning prompt information to the mobile terminal.

The fourth early warning prompt information is used for prompting that the engine model after the replacement is incorrect, and the user needs to confirm the engine model.

In an implementation, after receiving the changed model of the engine, the server compares the model with the target model. And if the model is the same as the target model, sending a notification that the model is matched correctly to the mobile terminal. If the model is different from the target model, a fourth early warning prompt message is sent to the mobile terminal to prompt the user that the replaced engine model is incorrect and needs to be replaced again.
