Specifically, the upper computer uses the current as a variable name of the hash table to obtain a storage address corresponding to the current, and marks the storage address as a second target address (the second target address is a storage address at which the current value is stored in the embedded storage device), and obtains a data length corresponding to the current, and marks the data length as a second target length (the second target length is a storage length at which the current value is stored in the embedded storage device).
Step S430: and the upper computer sends the third target address and the third target length to the embedded storage equipment.

step S510: the calculation module acquires the total amount of the third target data in a preset second time period in the past.
Specifically, the preset second time period is preferably 24 hours, that is, the total amount of the third target data, that is, the number of the third target data received by the upper computer in the last 24 hours is obtained by the calculation module, in this embodiment, the number of the third target data is 1440 since the third target data is sent every 1 second.
Step S520: the calculation module obtains an average value of the third target data in a second time period preset in the past.
Specifically, the calculation module obtains an average value of the values of the 1440 third target data in the last 24 hours.
Step S530: and the calculating module acquires the number of differences between the average value and each third target data in the past preset second time period, wherein the number of the differences is larger than a preset difference value, and the number of the differences is marked as a mutation number, wherein the preset difference value is a preset percentage of the average value.
Specifically, the preset percentage is preferably 20%, that is, the calculation module obtains the number of differences between the average value and each third target data in the last 24 hours, which is greater than the preset difference value, and marks the number as the number of sudden changes, where the number of sudden changes is the number of differences between the current value and the average value.
Step S540: the calculation module generates the first preset time period according to a ratio of the mutation number to the total number, wherein the first preset time period is smaller when the ratio is larger, and the first preset time period is larger when the ratio is smaller.
Specifically, the larger the ratio in this embodiment is, the larger the actual value change of the current value in the past 24 hours is, and the fluctuation is larger, so that the first preset time period needs to be reduced, that is, the number of the third target data acquired by the upper computer in the unit time is increased, so as to acquire more detailed and specific third target data, and thereby, the reason for the larger fluctuation is analyzed; on the contrary, the smaller the ratio is, the smaller the actual value change of the current value in the last 24 hours is, the smaller the fluctuation is, that is, the value of the third target data is relatively stable, so that the first preset time period can be increased, the number of the third target data acquired by the upper computer in unit time is reduced, the network communication burden is reduced, and the operating efficiency of the upper computer is improved.
In a sixth embodiment of the upper computer communication method applicable to the multi-model storage device, based on the first embodiment, the embedded storage device further includes a computing module; step S110, the method further includes the following steps:
step S610: and the embedded storage equipment stores the MAC address received for the first time and marks the MAC address as a safe address.
Specifically, each time the upper computer is in communication connection with the embedded storage device, the embedded storage device acquires the MAC address of the upper computer, and the embedded storage device stores the MAC address received for the first time and marks the MAC address as a secure address; namely, the upper computer which is in communication connection with the embedded storage device for the first time is a safe upper computer.

If not, go to step S660: and not allowing the upper computer to execute the step of acquiring the metadata description file in the embedded storage device in the step S110.
Specifically, if not, it is indicated that the current upper computer is not a secure upper computer, so that the current upper computer is not allowed to acquire the metadata description file of the embedded storage device, so as to improve data security.
In a seventh embodiment of the upper computer communication method applicable to the multi-model storage device, based on the third embodiment, the embedded storage device further includes a computing module; this embodiment further includes the following steps:
step S710: the calculation module obtains the total number of the parameter names in the metadata description file
。
Specifically, the calculation module obtains the total number of parameters stored in the embedded storage device, for example, 30 parameters.

。
Specifically, the total number of times of modifying the data in the embedded storage device, for example, 60 times, within the third preset time period (preferably 12 hours) obtained by the calculation module.
Step S730: the calculation module calculates a data risk coefficient D at the current moment:
wherein the content of the first and second substances,
in order to be said risk factor,
in order to modify the times that the interval time of the data in the embedded storage device is less than the preset time (preferably 5 seconds) within the third preset time period in the past, the value is greater than or equal to 0;
storing the modified data into the same second target address within the third preset time period in the past, wherein the value is greater than or equal to 0;
and taking the value of the second target address of which the modified data is stored in the third preset time period in the past to be greater than or equal to 0.
Specifically, the above formula is used for calculating a data risk coefficient in the embedded storage device, where the maximum value of the risk coefficient is 3, and the closer to 3, the more dangerous the data is; the specific analysis is as follows: due to the fact that
Is determined if
The larger the address at which the modified data occurs in the embedded memory device, the more abnormal the data modification, since it is usually necessary to modify several common parameters,
up to 30, i.e. 30 parameters have been modified, and, at this point,
taking 1; due to the fact that
Is determined if
The larger the data, the larger the number of data modifications occurring within the past 12 hours with an interval time of less than 5 seconds, the more abnormal such data modifications are, if any
The larger the number of modifications made to the same parameter, the more unusual,
the maximum may be 1.
