All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The storage of pollutant emission data is very important for current vehicles, especially heavy diesel vehicles, on which a memory card storing pollutant emission data is installed, so that whether the pollutant emission of the vehicle meets the national regulation requirements or not can be monitored by using the pollutant emission data later.
However, when the pollutant discharge data stored in the memory card is checked or exported, the memory card needs to be taken out from the storage device, and the pollutant discharge data can be checked or exported by using the reading device for reading the data in the memory card, which is very inconvenient for users or technicians, and cannot meet the requirement of the users or technicians on rapid processing of the pollutant discharge data stored in the memory card.
Based on this, an embodiment of the present application provides a pollutant discharge data processing method, which is applied to a terminal device, establishes a communication connection with a storage device storing pollutant discharge data, responds to a data service mode selected by a user on the terminal device, where the data service mode includes storage device data clearing, storage device storage capacity reading, or storage device data export, and processes the pollutant discharge data according to a corresponding data service mode. That is to say, this application embodiment can utilize terminal equipment to establish connection with storage device directly, through the data service mode that the user selected on terminal equipment, terminal equipment handles the pollutant emission data that storage device stored according to this data service mode, need not to take out the storage card in the storage device, utilizes extra reading device to handle pollutant emission data, can utilize terminal equipment directly to handle pollutant emission data in real time, can satisfy the quick processing demand of user to the pollutant emission data of storage.
For a better understanding of the technical solutions and effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the figure is a flowchart of a pollutant discharge data processing method according to an embodiment of the present application.
The pollutant emission data processing method provided by the embodiment of the application can be applied to terminal equipment, the terminal equipment is provided with a display screen, and a display interface of the display screen can display information selected by a user. The terminal device can be provided with a corresponding client so as to enable a user to directly obtain related content of pollutant emission data on a display interface of the client.
As an example, for a heavy-duty diesel vehicle, the terminal device may install a national phase six pollutant emission standard client, which is developed to implement the pollutant emission data processing method provided in the embodiment of the present application.
The pollutant discharge data processing method provided by the embodiment comprises the following steps:
and S101, establishing communication connection with a storage device for storing pollutant emission data.
In an embodiment of the present application, the terminal device establishes a communication connection with a storage device for storing pollutant emission data, and specifically, may be a communication connection between a client in the terminal device and the storage device for storing pollutant emission data. For example, the connection of the end devices and the storage devices may be implemented using a Universal Diagnostic Services (UDS) protocol.
And S102, responding to the data service mode selected by the user on the terminal equipment.
In the embodiment of the application, the terminal device may provide a service for processing pollutant emission data stored in the storage device in real time for a user, that is, the user may select a data service mode for processing the pollutant emission data on the terminal device. Wherein the data service mode comprises storage device data clearing, storage device storage capacity reading or storage device data exporting.
And the data clearing of the storage device means that the storage device is formatted and the data in the storage device is deleted. The storage device storage capacity reading is a determination of the storage capacity of the storage device, which may include the total storage capacity of the storage device and the stored storage capacity of the storage device. The data export of the storage device is to export pollutant emission data stored in the storage device and store the pollutant emission data in the terminal device or other devices, so that the pollutant emission data can be conveniently and directly read from the storage device in real time and can be conveniently and directly viewed in the terminal device.
As a possible implementation manner, a transmission packet of a data service mode may be defined by using the UDS protocol, so that after a user selects a corresponding data service mode, the terminal device performs corresponding packet transmission by using the transmission packet defined by the UDS protocol.
The UDS protocol defines a data service mode for emptying data of the storage device as 0x2E, the UDS protocol defines a data service mode for reading storage capacity of the storage device as 0x22, and the UDS protocol defines a data service mode for exporting data of the storage device as 0x 23.
In the embodiment of the present application, the UDS protocol may further define 0x27 as an authentication service, that is, an identity between the terminal device and the storage device is determined, and the pollutant emission data is processed after the identity is determined, so that security before the pollutant emission data is processed can be ensured. It is also possible to define its corresponding sub-function 0x19/0x1A for the authentication service 0x 27.
In the embodiment of the present application, the UDS protocol may further define 0x7E as a session mode, which can provide rights management and function isolation for data service mode in the terminal device.
And S103, processing the pollutant emission data according to the corresponding data service mode.
In the embodiment of the application, after the user selects the data service mode on the terminal device, the terminal device may process the pollutant discharge data according to the data service mode selected by the user.
As a possible implementation manner, if the data service mode selected by the user is the storage device data clearing, the terminal device may send a data clearing message to the storage device by using the communication connection, so as to clear the pollutant emission data stored in the storage device.
When the storage device stores pollutant emission data, the storage device can be divided into a plurality of storage areas, wherein the storage areas comprise a regulation real-time data storage area and a regulation blind area data storage area. The data may be stored in a format defined by a user during storage, for example, the storage format may adopt a format that occupies a small storage space, so as to store more data in the limited storage space of the storage device.
As an example, the pollutant discharge data may be stored using a format including a start storage identifier, a currently stored pollutant discharge data packet length, and a specific content of the currently stored pollutant discharge data, the pollutant discharge data being stored in units of 1 Kilobyte (KB), and if the pollutant discharge data is less than 1KB, the redundant data FF is filled until the data is 1 KB.
After storing pollutant emission data in a plurality of storage areas of the storage device, a data flush message can be sent to the storage device by using a data service mode 0x2E corresponding to the data flush of the storage device defined by the UDS protocol.
The Data clear message relates to a specific message as follows, including a Data Identifier (DID), Data (Data), a session mode, and a security access sub-function, where 03 in Data represents a regulation real-time Data storage area, and 02 represents a regulation blind area Data storage area.
When the storage device is actually formatted and pollutant emission data in the storage device is emptied, data can be erased in a way of writing an Identifier (ID), in the erasing process, if the data is not erased, a negative response 0x78 needs to be fed back, and a negative response is fed back every 5 seconds until a positive response is obtained, which represents that the data is erased.
As another possible implementation manner, if the data service mode selected by the user is storage capacity reading of the storage device, the terminal device may send a storage capacity reading message to the storage device by using the communication connection, so as to read the storage capacity of the storage device.
Specifically, the storage capacity read message may be sent to the storage device by using the storage capacity read corresponding to the data service mode 0x22 defined by the UDS protocol.
The storage device storage capacity comprises the total storage capacity and the stored storage capacity of the storage device, so that the user can respectively obtain the total storage capacity and the stored storage capacity of the storage device.
As an example, the terminal device sends a total storage capacity read message to the storage device using the communication connection in order to read the total storage capacity of the storage device.
As another example, the terminal device sends a stored capacity read message to the storage device using the communication connection in order to read the stored capacity of the storage device.
Since the storage apparatus includes a plurality of storage areas such as a law real-time data storage area and a law blind area data storage area, it is possible to distinguish with different DID for different storage areas.
When data storage is performed, redundant data FF is included in pollutant emission data, and only valid data except the redundant data in a plurality of storage areas can be read.
Reference is made to the following table:
as yet another possible implementation, if the data service mode selected by the user is storage device data export, the terminal device may send a data export message to the storage device using the communication connection in order to export pollutant emission data stored in the storage device.
Specifically, a data export message may be sent to the storage device by using the storage device data export corresponding data service mode 0x23 defined by the UDS protocol.
The specific messages involved in the data export message are shown below, including data service mode, session mode, secure access sub-function, address and length format, and supporting address fields.
It can be seen from the content included in the data export message that, when the data export of the storage device corresponding to 0x23 is implemented, the data export of the storage device is supported only after the security authentication is completed in the storage device data export session mode.
When the terminal device performs the 0x23 service, if the address and length format is other than 0x44, data export is not supported. And setting an integral multiple of 1KB for reading every time the terminal equipment conducts data derivation, namely reading according to the storage format of the pollutant emission data.
Specifically, the terminal device sends a data export message to the storage device by using the communication connection, reads pollutant emission data stored in the storage device, and converts the format of the pollutant emission data into a display format so as to export the pollutant emission data stored in the storage device. The display format may be in hexadecimal ASCII code format.
As an example, when reading the pollutant discharge data stored in the storage device, each line of data is 1KB, and then the read pollutant discharge data is exported in the format of hexadecimal ASCII code and stored in the txt file specified by the terminal device.
For example, if the pollutant emission data stored in the storage device is 232300080102030405060708 FF and the total length of the data is 1KB, the data is exported and stored into a line in the txt file, and the return line feed character is added at the end.
In the embodiment of the application, the pollutant discharge data comprises redundant data and effective data, and only the effective data can be read, so that the data reading efficiency is improved, the data volume of the data in the transmission process is reduced, and the data exporting efficiency is accelerated.
Specifically, the terminal device sends a data export message to the storage device by using the communication connection, reads pollutant emission data stored in the storage device, and deletes redundant data so as to export valid data, that is, when reading the pollutant emission data stored in the storage device, only the valid data is converted, and invalid data FF at the end of each pollutant emission data is removed.
When the derived data is stored, the format conversion can be carried out on the data acquisition time in the data storage process, a separator space is supplemented after the data acquisition time after the format conversion, then pollutant emission data corresponding to the data acquisition time is added to the separator space, and finally an enter line-changing character is supplemented.
For example, the data acquisition time is stored in a format of 210608164450, and converted to a display format of "2021-06-0816: 44: 50" at the time of data export.
In the embodiment of the present application, a terminal device may display an interface for processing pollutant discharge data, and referring to fig. 2, a schematic display interface of the terminal device provided in the embodiment of the present application is shown, and as can be seen from the diagram, the display interface includes regions corresponding to 3 data service modes, which are a storage device data clearing region 210, a storage device storage capacity reading region 220, or a storage device data exporting region 230, respectively. The storage device data clearing area 210 comprises an clearing regulation real-time data storage area 211 and a clearing regulation blind area data storage area 212, and the storage device storage capacity reading area 220 comprises a storage device total storage capacity reading area 221 and a storage device stored capacity reading area 222, that is, the storage device storage capacity can be displayed on the terminal device, and the condition that the storage device stores pollutant emission data can be visually shown to a user. The storage device data lead-out area 230 includes a lead-out total data area 231 and a lead-out valid data area 232.
The pollutant emission data processing method provided by the embodiment of the application is applied to terminal equipment, communication connection with storage equipment for storing pollutant emission data is established, a data service mode selected by a user on the terminal equipment is responded, the data service mode comprises storage equipment data emptying, storage equipment storage capacity reading or storage equipment data exporting, and the pollutant emission data is processed according to the corresponding data service mode.
