s1, oil tank parameter configuration and updating are carried out through a parameter configuration module of the oil tank monitor, and the parameter configuration module of the oil tank monitor adopts dynamic password management when the parameters are configured or updated.
Before the oil tank monitor is used, relevant parameters of the oil tank need to be input according to the national tank capacity table standard, and the tank capacity table can be automatically generated or manually recorded according to the parameters of the oil tank. In order to avoid illegal tampering of the configured parameters of the tank monitor by personnel in the gas station, the tank monitor needs key management when configuring and updating the parameters, otherwise, the function of setting the tank parameters of the tank monitor cannot be started.

Assuming that the internal diameter of the oil tank is 150cm, the amount of oil changes to V = π × 150 for every 0.1cm change 2 ×0.1＝70686(cm 3 ) =7.01 (liter). Assuming that the parameters between the tank monitor and the data management platform have been configured, the tank monitor needs to configure these parameters of the tank so that when the tank monitor reads 0.6cm of data from the level gauge (which may be the difference between the two level gauge data), it knows that the tank outputs (or inputs) 0.6 × 7.01=4.26 liters of oil.
The liquid level meter can monitor the change of 0.1cm, so that the oil tank monitor can monitor the data change as long as the oil tank has the output oil quantity, and the change condition is uploaded to the data management platform. The data uploading strategy of the oil tank monitor can be set to be uploading at regular time, namely, uploading every fixed time (such as 1 minute); it is also possible to arrange for real-time uploading, i.e. uploading each time a change in the data is collected, but there is also a certain time interval between two data uploads, e.g. 1 second, since the tank monitor has a certain frequency of reading the data of the level gauge.
The oil tank monitor and the data processing platform share a secret key k2 and an encryption algorithm E; the specific steps of the data processing module for encrypting the oil quantity change data in the oil tank are as follows:
s21, encrypting oil volume change data x in the oil tank by the first data processing module to obtain y = E (k 2, x), and then sending an encrypted ciphertext y to a data management platform;
s22, the data management platform stores the relevant data of the ciphertext y into the database. And the related data of the ciphertext y is the ciphertext y or the data x obtained by decrypting the received ciphertext y by the data management platform.
And S3, a second data acquisition module of the oiling machine data acquisition unit acquires the oil filling amount of the oiling machine and sends the oil filling amount to a second data processing module, the second data processing module processes the received dynamic change data of the oil filling amount, calculates the data of the oil filling amount after the data change is stopped, encrypts the data of the oil filling amount, and sends the encrypted data to the data management platform through the second communication module.

The ciphertext cdata related data is the ciphertext cdata or data obtained by decrypting the received ciphertext cdata by the data management platform.
And S4, the data management platform compares the received related data of the ciphertext y of the first communication module with the related data of the fueling quantity ciphertext cdata of the second communication module, judges whether the two groups of data are matched, and if the two groups of data are not matched, the configuration parameters of the oil tank monitor are not accurate or the data of the oiling machine are not accurate. And if the difference rate of the two groups of data is basically kept fixed, the configuration parameters of the oil tank monitor are inaccurate, otherwise, the data of the oiling machine are judged to be inaccurate.
Therefore, the system and the method for monitoring the fuel quantity of the gas station can solve the problems that the data inconsistency between the recorded data and the actual fuel quantity of the conventional meter is difficult to find and the fuel dispenser is inaccurate.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the invention without departing from the spirit and scope of the invention.
