the controller compares the received identification of the sub-tool cabinets, the model information of the tools and the identification information according to the tool information in the memory so as to judge whether the tool taken out by the user has errors or not, and the method comprises the following steps:

firstly, the controller classifies the received type information of the tools, namely classifying the same type information of the tools into one type, and then counting the number one of the type information of each type of tool, so that the number one of the tools of each type in the sub-tool cabinet is obtained; the controller reads the model information of the nearest tool in the sub-tool cabinet corresponding to the identifier of the sub-tool cabinet in the tool information in the memory, which is the same as the received identifier of the sub-tool cabinet, and classifies the model information, namely, the model information of the nearest tool in the sub-tool cabinet in the tool information is classified into one class, and then the number two of the model information of each type of tool in the sub-tool cabinet in the tool information is counted, so that the number two of the tools of each type in the sub-tool cabinet in the tool information is obtained;

then, subtracting the first number of tools of the type in the tool division cabinet from the second number of tools of the type in the tool division cabinet in the tool information of the same type as the tools to be taken out to obtain the actual number of the tools to be taken out, if the actual number is different from the value of a counter corresponding to the tool division cabinet, indicating that the number of the tools to be taken out is incorrect, displaying the information that the taken out tools are wrong on a touch screen, filling a square frame corresponding to the tool division cabinet into red to indicate that the taken out tools are wrong, opening an intelligent electronic lock on a cabinet door of the tool division cabinet, starting an alarm to send a voice message to alarm that the tools of the tool division cabinet are taken out in a wrong way, and returning to SA-5 for execution; if the actual number is the same as the value of the counter corresponding to the sub-tool cabinet, it indicates that the number of the tools to be taken out is correct, then the number one of the tools of other types in the sub tool cabinet is respectively compared with the number two of the tools of the same type with the same size in the sub tool cabinet in the tool information one by one, if the numbers are the same, the tools of other types are not taken by mistake, at the moment, the square frame corresponding to the sub tool cabinet is filled to be green, thereby showing that the tools taken out from the sub-tool cabinet are correct, and the received model information and the identification information of the tools in the RFID labels of all the tools in the sub-tool cabinet replace the model information and the identification information of the nearest tool in the sub-tool cabinet in the memory respectively, respectively serving as the updated model information and the updated identification information of the tool in the latest sub-tool cabinet; if the tools are different, the fact that the tools of other models are mistakenly taken is indicated, the fact that the taken tools have the wrong information is displayed on the touch screen, the square frame corresponding to the sub-tool cabinet is filled with red, the fact that the taken tools have the errors is indicated, the intelligent electronic lock on the cabinet door of the sub-tool cabinet is opened, the alarm is started to send out a voice message alarm to prompt that the tools of the sub-tool cabinet are taken by the mistake, the operation is returned to SA-5, and therefore the users can perform the operation in the state that the users mistakenly take the tools in the tool cabinet, the red filling in the corresponding square frame on the state interface correspondingly is achieved, the voice message alarm is sent out to prompt for error correction, the use safety of the tools is improved, and the defect that the use safety of the tools is not enough due to the fact that the users mistakenly take the tools in the tool cabinet in the prior art and the corresponding RFID.

SA-8: after all the yellow boxes filled on the state interface displayed by the touch screen are changed into green boxes filled on the state interface, representing that the tool to be taken out is completely and correctly taken out, displaying a return button on the state interface, and returning to the SA-1 for execution by clicking the return button;

in addition, after the received model information and identification information of the tools in the RFID tags of all the tools in the sub-tool cabinet replace the model information and identification information of the tool in the latest sub-tool cabinet in the memory, respectively, the controller needs to transmit the tool information in the memory to the backup platform in the form of a message for backup; the controller transmits the tool information in the memory to the WIFI router in a message form, and the WIFI router receives the tool information and transfers the tool information to the backup platform; the WIFI router is in the WLAN.

The method for the controller to transmit the tool information in the memory to the backup platform in the form of messages is operated on the controller, and comprises the following processes:

the controller transmits an information packet of tool information to the backup platform, and transmits the bandwidth of the information packet by virtue of the change of the loss rate during the period.

SB-1: transmitting the information messages of the tool information of the designated number to a backup platform in the designated time interval by means of the bandwidth for transmitting the information messages;

SB-2: receiving the initial amount of the bandwidth and the loss rate which are responded by the backup platform and used for receiving the information message within the specified time interval; the initial quantity of the loss rate is 100% - (the number of the received information messages in the specified time interval size ÷ the specified number);

SB-3: deriving a bandwidth coefficient; the bandwidth coefficient is 100% - (the bandwidth for receiving the information message/the bandwidth for transferring the information message);

SB-4: obtaining a result of the loss rate by means of the initial amount of the loss rate and the bandwidth coefficient;

SB-5: and transmitting the bandwidth of the information message by means of the result change of the loss rate.

If the controller transmits a specified number of information packets of the tool information C1 to the backup platform in the specified time interval size P, the bandwidth for transmitting the information packets is K1, the number of information packets of the tool information actually received by the backup platform in the specified time interval size P is K2, the bandwidth for receiving the information packets is K3, the backup platform derives the initial amount of the loss rate, obtains the initial amount I1 of the loss rate as 100% - (K2 ÷ C1), then the backup platform transmits the initial amount I1 of the loss rate and the bandwidth K3 for receiving the information packets to the controller, the controller derives the bandwidth coefficient C2 by using the equation C2 ═ 100% - (K3 ÷ K1), then derives the result of the loss rate by using C2 and I1, and the result of the loss rate varies the bandwidth for transmitting the information packets; here, the bandwidth K1 for transmitting the information packet is equal to the byte amount/P of all information packets transmitted in the time interval size P, and the bandwidth K3 for receiving the information packet is equal to the byte amount/P of all information packets received in the time interval size P.

The current approach broadly employs I1 as the last evaluation number for loss rate and as a proof of change in bandwidth used to transfer the information message; the invention absorbs the bandwidth coefficient into the loss rate derivation mode, and the bandwidth coefficient is favorable for balancing the error of the current loss rate evaluation so as to improve the accuracy of the loss rate evaluation; the bandwidth for transmitting the information message and the bandwidth for receiving the information message have direct effects on the loss rate, and when the bandwidth for transmitting the information message is higher than the bandwidth for receiving the information message, the probability of losing the message is not small; when the bandwidth for transmitting the information message is not higher than the bandwidth for receiving the information message, the probability of losing the message is not high; therefore, the ratio of the bandwidth for transmitting the information message to the bandwidth for receiving the information message is used as a coefficient to perform loss rate evaluation, which is beneficial to correctly evaluating the loss rate, thereby reducing the adverse effect of bandwidth variation on the loss rate.

Within the present invention, the derived equation for I1 can also be: i1 is 100% - (K2 ÷ (H1-L1)), H1 is the sequence code of the longest information packet transmitted within a specified time interval size P, and L1 is the sequence code of the shortest information packet.

In the present invention, the method for obtaining the result of the dropout rate by using the starting amount of the dropout rate and the bandwidth factor comprises: the loss rate result Z1 is derived by using a coefficient statistical model through C2 and I1, and the detailed equation is:

z1 (Y1 × I1) + (Y2 × C2), where Y1 and Y2 are preset coefficients one and two, and Y1+ Y2 (100%) can make Y1 and Y2 both take on 50%. The first and second coefficients can also be preset by taking into account such factors as bandwidth.

The method for the controller to transmit the tool information in the memory to the backup platform in the form of messages is operated on the controller, and comprises the following processes:

SC-1: transmitting the information messages of the tool information of the designated number to a backup platform in the designated time interval size by means of the bandwidth for transmitting the information messages;

SC-2: receiving the initial amount of the bandwidth and the loss rate which are responded by the backup platform and used for receiving the information message within the specified time interval; the initial quantity of the loss rate is 100% - (the number of the received information messages in the specified time interval size ÷ the specified number);

SC-3: deriving a bandwidth coefficient; the bandwidth coefficient is 100% - (the bandwidth for receiving the information message/the bandwidth for transferring the information message);

SC-1-SC-3 are the same as SB-1-SB-3, respectively.

SC-4: deriving the average of S bandwidth coefficients and the average of S initial loss rates, wherein S is a natural number greater than one;

SC-5: respectively multiplying and adding the combination coefficients by the average number of the S bandwidth coefficients and the average number of the initial amount of the S loss rates to obtain a result of the loss rate;

in the invention, S bandwidth coefficients and the initial quantity of S loss rates are obtained by repeatedly executing SC-1-SC-3 for S times, and the average of the S bandwidth coefficients and the average of the initial quantity of the S loss rates are derived, so that the result of obtaining the loss rates is derived by the combination of the averages and the coefficients; for example, a total time period is 2500ms, each interval is 500ms, and information messages of a specified number of tool information are transmitted to the backup platform, and five operations are performed, so as to obtain the initial amount of five bandwidth coefficients and five loss rates.

The initial amount and bandwidth factor for the loss rate are still given by I1 and C2: by deriving by performing the multiplication and the addition of the combination coefficients respectively for the average of the S bandwidth coefficients and the average of the starting amount of the S loss rates, the result of obtaining the loss rate can be: obtaining S I1 and C2 through S runs and obtaining their average numbers I1Q and C2Q for I1 and C2, respectively, the result Z1 of the loss rate is obtained by the following equation:

z1 (Y1 × I1Q) + (Y2 × C2Q), where Y1+ Y2 are 100%, which allows both Y1 and Y2 to take on 50%.

SC-6: and transmitting the bandwidth of the information message by means of the result change of the loss rate.

As such, in a state where the bandwidth for receiving the information packet is not changed, the bandwidth for transmitting the information packet is made low, and the ratio of the bandwidth for receiving the information packet to the bandwidth for transmitting the information packet is made high, whereby the bandwidth factor is made low, and the result of the loss rate is made low. Changing the bandwidth for transmitting the information message according to the result of the loss rate further includes comparing the result of the loss rate with a preset critical number, and if the result of the loss rate is higher than the preset critical number, reducing the bandwidth for transmitting the information message according to the result of the loss rate for a long time.

Therefore, the result of the loss rate is obtained by the average of the bandwidth coefficients and the average of the initial amount of the loss rate, and the derivation is performed by the average, so that the error of the information collected at one time under the action of a random condition is prevented, and the accuracy of the loss rate evaluation can be improved.

The present invention has been described in an illustrative manner by the embodiments, and it should be understood by those skilled in the art that the present disclosure is not limited to the embodiments described above, but is capable of various changes, modifications and substitutions without departing from the scope of the present invention.
