Step 4-2: deducing the weight of each hacking program intrusion prompting message according to the highest bit rate of data transmission and the average number of the bit rates of the data transmission of each controller I in a preset time length;

8. The substation room field inspection device of claim 6, wherein the derivation unit is further configured to derive a weight for each controller one via a weight derivation equation, the weight derivation equation being:
Figure 546592DEST_PATH_IMAGE004
；
in the equation, x is a positive integer, A x Is the weight of the xth controller one, B x1 Is the highest bit rate, B, of the xth controller-data transfer within a predetermined time period x2 Is the average of the bit rates of the data transfers of the xth controller in a preset time period,
Figure DEST_PATH_IMAGE005
is the sum of all controllers-the highest bit rate of data transfer in a predetermined time period added,
Figure 499898DEST_PATH_IMAGE006
the total amount is obtained by adding the bit rate average numbers of data transmission of all the controllers in a preset time length; if the number of the controllers corresponding to the hacker program intrusion prompting message is one, the weight quantity corresponding to the controller corresponding to the hacker program intrusion prompting message is used as the weight quantity of the hacker program intrusion prompting message, and if the number of the controllers corresponding to the hacker program intrusion prompting message is higher than two, the total sum of the weight quantities of all the controllers corresponding to the hacker program intrusion prompting message is used as the blackWeight of guest program intrusion alert message;
the utility unit is further used for deducing the utility amount of each hacking program intrusion prompting message through a utility amount derivation equation, wherein the utility amount derivation equation is as follows:
L Y =60÷{P-Q Y }；
in the equation, L Y Is the effective amount of the hacker program intrusion prompt message Y, P is the current time, Q Y Is the time of formation of the hacking program intrusion alert message Y.
