The calibration information generation method based on the oil quantity meter comprises the following steps:
and S101, acquiring the communication information of the instrument.
In this embodiment, the meter communication information is handshake decryption information sent by the fuel gauge through the reserved communication interface.

In this embodiment, the authorization request information is used to trigger the calibration information generation system to identify and verify the meter communication information.
In this embodiment, the handshake decryption authentication information includes encryption and decryption algorithm information used by the fuel gauge.
In this embodiment, the meter communication information may be acquired through the communication interface reserved for the fuel gauge, and may also be acquired through other communication methods. The other communication modes include various wireless communication modes and wired communication modes.
In this embodiment, after the fuel gauge sends the gauge communication information to the host computer (i.e., the gauge information generation system), the fuel gauge enters the calibration mode, and the calibration mode is used to determine whether to upload the fuel information and the gauge display information according to the success or failure of the handshake decryption process.
S102, judging whether the instrument communication information is matched with preset instrument correction information, if so, executing the steps S103-S104; if not, the flow is ended.
In this embodiment, the step may be understood as a handshake decryption step between the calibration information generation system and the fuel gauge; if the oil quantity is finished, the process of oil quantity adaptation calibration (namely the process from S103 to S104) is started.
In this embodiment, the preset instrument correction information includes an encryption/decryption algorithm that an upper computer (i.e., a calibration information generation system) has, and a specific encryption/decryption algorithm refers to a type of the encryption/decryption algorithm.
In this embodiment, the process of determining whether the meter communication information matches the preset meter calibration information may be understood as determining whether the same encryption/decryption algorithm or encryption/decryption algorithm type exists between the fuel quantity meter and the calibration information generation system, and if the same encryption/decryption algorithm or encryption/decryption algorithm type exists between the fuel quantity meter and the calibration information generation system, it indicates that the fuel quantity meter can interact with the calibration information generation system, and a symmetric key for information interaction between the fuel quantity meter and the calibration information generation system can be determined by using the same. And the above process is called a handshake decryption process.
In this embodiment, the purpose of the handshake decryption is to adjust the read-write control authority of one parameter in the fuel gauge. After the fuel gauge uploads the algorithm factor, the upper computer performs authorization calculation according to the algorithm factor and issues a calculation result to the fuel gauge so that the fuel gauge adjusts the read-write control authority of one parameter in the fuel gauge according to the calculation result.
In this embodiment, after the symmetric key is determined, the fuel gauge and the calibration information generating system may perform encryption interaction according to the symmetric key, where the data transmitted in the interaction process is encrypted data generated by encrypting the symmetric key, the private key of the fuel gauge, and the public key of the calibration information generating system.

In the present embodiment, the oil amount information can be simply understood as resistance value information representing the oil amount.
In this embodiment, the meter display information includes the grid number information displayed by the fuel gauge or the percentage information displayed by the fuel gauge, and the form of the meter display information is not limited in this embodiment.
In this embodiment, the meter display information and the oil amount information correspond to each other, that is, 50% of the meter display information corresponds to a resistance value of 50% of the oil amount.
And S104, generating calibration information according to the meter display information and the oil quantity information.
In the present embodiment, the calibration information is generated by extracting information of a fixed number of grids or a fixed percentage from the meter display information and the oil amount information.
For example, the calibration information is 10%, 20%, 30%, 40%, etc. meter display information and its corresponding oil amount information.

In this embodiment, the execution main body of the calibration information generation method based on the fuel gauge may be a windows application software running in a computer, and the software can be used to send an authorized decryption request (i.e., meter communication information) to the fuel gauge for processing, acquire fuel amount information (which may include a fuel sensor parameter value during a fuel tank fuel drain process) in real time, calibrate corresponding fuel amount information and meter display information, and calibrate the meters to be calibrated in batches using calibration information obtained by calibration.
In this embodiment, the method is a calibration information obtaining method supporting the oil adding and discharging operation processes of different types of oil tanks. The method can automatically acquire the fuel quantity information (the fuel quantity information comprises fuel quantity sensor parameters of a fuel tank) and the instrument display information (such as fuel quantity percentage or fuel quantity grid threshold), and can also determine the display mode of the instrument display information (namely the instrument display information can be displayed according to the fuel quantity percentage relationship and can also support the fuel quantity grid display). Meanwhile, the oil meter is a meter which can calibrate the calibration information according to the method scheme and can permanently record the calibration information (the calibration information can be stored after the power is cut off and cannot disappear after the power is cut off).
It can be seen that, by implementing the calibration information generation method based on the fuel gauge described in fig. 1, the gauge communication information sent by the fuel gauge can be preferentially obtained to confirm that the fuel gauge is requesting authorization from an upper computer (an execution main body in this embodiment), and the fuel gauge is triggered to enter a calibration state; the upper computer performs handshake decryption according to the received meter communication information, and judges whether the fuel gauge can interact with the upper computer, namely whether the upper computer gives interactive authorization to the fuel gauge; when the meter communication information is matched with the meter correction information, the upper computer starts to acquire meter display information and oil quantity information uploaded by the oil quantity meter in the correction state; and finally, the upper computer generates calibration information with a corresponding relation according to the instrument display information and the oil quantity information so that other instruments of the same type as the oil quantity instrument can be directly downloaded for use. Therefore, by implementing the implementation mode, the standardized generation process of the calibration information can be completed through four steps of authorization request, handshake decryption, data storage and data processing, so that the acquisition efficiency of the calibration information is further improved under the condition that the data is accurate, the efficiency can be improved for the correction process of other meters of the same type as the fuel gauge, and meanwhile, the generation of human errors can be avoided.
