Firstly, respectively setting different data acquisition modules on different power distribution equipment, wherein the data acquisition modules are responsible for collecting monitoring data of the power distribution equipment, the monitoring data refer to running data of the power distribution equipment, wherein the two different data acquisition modules can be mutually communicated, main characteristic values are also stored in the data acquisition modules, the first characteristic values are up to an N characteristic value, and the first characteristic values are up to an N characteristic value respectively corresponding to first password values, the main characteristic values are pre-generated, the first characteristic values are up to the N characteristic value, the first password value is up to the N characteristic value, a generation method of the first password value is introduced in the following, after a first time interval is passed, the data acquisition modules finish one-time updating of the first password value up to the N password value, namely the first password value stored by the data acquisition modules is not fixed and unchanged, but is dynamically updated, the safety of the first password value up to the N password value is enhanced, each data acquisition module respectively passes through a plurality of other data acquisition modules, the first password value is up to the N characteristic value, namely, a plurality of monitoring data acquisition modules are transmitted to the data acquisition modules A and B adjacent to the data acquisition modules, and a data acquisition module B can be used for transmitting the data acquisition path after the first data acquisition module and the monitoring module B, the data acquisition module is used for transmitting the data acquisition path to the data acquisition module, and the data acquisition module is provided with a plurality of the data acquisition monitoring module, and the data acquisition module is used for encrypting a data path after the data acquisition path is used, and finally, after receiving the monitoring data collected by different data acquisition modules from the first data acquisition module, the remote server module analyzes and processes the monitoring data by using a machine learning algorithm to obtain an analysis result, and under the condition that the analysis result is abnormal, for example, the analysis result shows that the probability of the power distribution equipment to fail can be ninety percent, and a reminding message is timely pushed to related contacts, so that the power distribution equipment is subjected to short maintenance in advance, or the power distribution equipment is directly and quickly replaced, thereby avoiding overlong power failure time caused by positioning the failed power distribution equipment in the future, and further improving the reliability of the power distribution network.
Further, among the different data acquisition modules, there are a first data acquisition module, and a second data acquisition module up to an nth data acquisition module, and the first data acquisition module, and the second data acquisition module up to the nth data acquisition module complete a change after each lapse of a preset first time interval.
Further, the first data acquisition module and the second data acquisition module complete a change after each preset first time interval until the nth data acquisition module, including the following steps:
Step 1, dividing the first time interval into N second time intervals, namely a second time interval 1 and a second time interval 2 until a second time interval N;
Step 2, each data acquisition module randomly generates notification messages before the second time interval 1 is finished, if the notification messages are generated, the notification messages are sent to each other data acquisition module, the intention of the data acquisition module sending the notification messages to become a target data acquisition module is represented, when the second time interval 1 is finished, the data acquisition module sending the notification messages is regarded as the target data acquisition module under the condition that the data acquisition module sending the notification messages does not receive the notification messages from the other data acquisition modules, otherwise, the data acquisition module with the highest priority in all the data acquisition modules sending the notification messages is regarded as the target data acquisition module, and the target data acquisition module is regarded as the first data acquisition module;
and 3, repeating the same method as the method for determining the first data acquisition module respectively before the second time interval 2 is over until the second time interval N is over, so as to determine the second data acquisition module respectively until the Nth data acquisition module.
Specifically, in step 1, the first time interval is divided into N second time intervals, namely, a second time interval 1, and a second time interval 2 until a second time interval N, in step 2, before the second time interval 1 ends, each data acquisition module randomly generates a notification message, that is, each data acquisition module may generate a notification message, or may not generate a notification message, if a notification message is generated, the notification message is sent to each other data acquisition module, meaning that the data acquisition module sending the notification message wants to become a target data acquisition module, and in the second time interval 1 ends, if the data acquisition module sending the notification message does not receive a notification message from another data acquisition module, indicating that no other data acquisition module wants to become a target data acquisition module, in step 2, the data acquisition module sending the notification message is regarded as a target data acquisition module, otherwise, the data acquisition module with the highest priority among all data acquisition modules sending the notification message may be regarded as a target data acquisition module, if the data acquisition module passes the data acquisition module and the first data acquisition module, and the second data acquisition module is repeatedly set to be the same as a target data acquisition module before the second time interval 3, and before the second time interval 1 ends, the data acquisition module is repeatedly invaded by the first time interval 3, and before the data acquisition module is repeatedly invaded by the second time interval is not at the first time interval 3, and before the data acquisition module is repeatedly subjected to the first time interval is completed, and the third data acquisition module is up to the Nth data acquisition module. It should be noted that, among the different data acquisition modules, the first data acquisition module is generated for the first time, and the second data acquisition module up to the nth data acquisition module may also use the methods from the 1 st step to the 3 rd step.
In addition, in the case that the total number of the data acquisition modules is changed, the first data acquisition module and the second data acquisition module complete a change through the method from the 1 st step to the 3 rd step, for example, a new data acquisition module is added or a failed data acquisition module is abandoned, and in the case that any one of the first data acquisition module, the second data acquisition module and the nth data acquisition module is invaded, the first data acquisition module and the second data acquisition module complete a change through the method from the 1 st step to the 3 rd step, and the change does not send a notification message through setting the invaded data acquisition module, so that the invaded data acquisition module is not used as a new first data acquisition module and the new second data acquisition module is not used as one of the new nth data acquisition module. By the method from the step 1 to the step 3, the data acquisition module generating the password value is not fixed and is dynamically changed, so that the reliability can be improved, and even if the data acquisition module generating the password value is invaded, the password value can be generated by other data acquisition modules.
Further, after each preset first time interval, one update of the first password value to the nth password value stored in the data acquisition module is completed, and the method comprises the following steps:
Step 1, each other data acquisition module sends a first characteristic value stored by the first data acquisition module to the first data acquisition module, the first data acquisition module respectively uses the main characteristic value stored by the first data acquisition module and the received first characteristic value to generate a first password value, and the first data acquisition module respectively transmits the generated first password value to each corresponding other data acquisition module for storage;
And 2, each other data acquisition module sends the self-stored K characteristic value to the K data acquisition module, the K data acquisition module respectively uses the self-stored main characteristic value and the received K characteristic value to generate a K password value, and the K data acquisition module respectively transmits the generated K password value to each corresponding other data acquisition module for storage, wherein K is any integer greater than or equal to two and less than or equal to N.
Specifically, according to the above, after each first time interval, the first data acquisition module and the second data acquisition module complete a change until the nth data acquisition module, and at the same time, the first password value stored in the data acquisition module can be updated once until the nth password value is updated, in step 1, each other data acquisition module sends the first characteristic value stored in itself to the first data acquisition module, the first data acquisition module generates the first password value by using the main characteristic value stored in itself and the received first characteristic value, the specific generation method may be encryption processing the main characteristic value stored in itself and the received first characteristic value, then the first data acquisition module transmits the generated first password value to each other data acquisition module corresponding to the first characteristic value transmitted to the first data acquisition module, in step 2, each other data acquisition module sends the K characteristic value stored in itself to the kth data acquisition module by repeating the method in step 1, so as to obtain the kth password value, where K refers to any data acquisition module which is equal to or greater than two integers and less than N and is the first data acquisition module which needs to acquire the first characteristic value and the first data acquisition module. By the method, the first password value and the N-th password value stored by the data acquisition module are dynamically changed, and when the password value is used for encrypted transmission of the monitoring data, the safety can be improved.
Further, in the different data acquisition modules, a first data acquisition module and a second data acquisition module are arranged until an nth data acquisition module, wherein the total number of secret levels corresponding to the monitoring data collected by the data acquisition modules is the same.
Specifically, N is the same as the total number of secret levels corresponding to the monitored data collected by the data collection module, and is also the same as the total number of password values stored by the data collection module, according to the above, the generation of the password values is related to the main feature values and the feature values, different password values are generated by different main feature values and feature values, the complexity of different password values is also different, when the data collection module performs encrypted transmission of the monitored data through the password values, different password values can be selected according to the secret levels corresponding to the monitored data, the higher the secret level is, the more complex the used password value is, for example, the higher the secret level corresponding to the monitored data is, the first password value is selected to be used because the complexity of the first password value in all the password values is the highest, in this way, for the monitored data with higher corresponding secret levels, the encrypted transmission is safer because the higher the complexity of the password values is, the higher the difficulty of being cracked is, for the monitored data with lower corresponding secret levels, the efficiency of encrypted transmission can be improved, the lower the complexity of the password values is, and the processing time is less spent.
Further, in the process that the data acquisition module passes through a plurality of other data acquisition modules and transmits the collected monitoring data to the first data acquisition module in an encrypted manner, the method comprises the following steps:
step 1, a first data acquisition module sets a marking value to be zero, and a marking value threshold value is preset;
Step 2, the first data acquisition module sends first request information to the data acquisition modules except the first data acquisition module, and after the first request information is received, the data acquisition module sends first reply information to the first data acquisition module, wherein the first reply information comprises the ID value of the data acquisition module and the ID values of other data acquisition modules adjacent to the data acquisition module;
Step 3, under the condition that the position of the first data acquisition module is not changed, ending all the steps, under the condition that the position of the first data acquisition module is changed, the first data acquisition module sends second request information to the adjacent data acquisition module, the adjacent data acquisition module sends second reply information to the first data acquisition module after receiving the second request information, the second reply information comprises the ID value of the adjacent data acquisition module, and the first data acquisition module determines the category to which the adjacent data acquisition module belongs according to the second reply information;
Step 4, regenerating a transmission path of the monitoring data to the first data acquisition module under the condition that the adjacent data acquisition modules belong to the class D, setting a marking value to be zero, and skipping the first data acquisition module to send first request information;
Step 5, judging whether the marking value is larger than a marking value threshold value under the condition that the adjacent data acquisition modules do not belong to the category D, and regenerating a transmission path of monitoring data to the first data acquisition module under the condition that the marking value is larger than the marking value threshold value, setting the marking value to be zero, and skipping the first data acquisition module to send first request information;
And step 6, under the condition that the marking value is smaller than or equal to the marking value threshold value, generating a new transmission path of the monitoring data to the first data acquisition module based on the transmission path of the monitoring data to the first data acquisition module before the position of the first data acquisition module is changed, accumulating the marking value, and skipping the first data acquisition module to send the first request information.
Specifically, in the process that the data acquisition module encrypts and transmits the collected monitoring data to the first data acquisition module through a plurality of other data acquisition modules, the position of the first data acquisition module may change due to the change of electricity load and the like, a new transmission path of the monitoring data to the first data acquisition module needs to be generated at this time, and the whole transmission path is generally regenerated, but in doing so, a lot of time is spent, the transmission of the monitoring data is delayed, and the reliability of the power distribution network is further affected, and in order to solve the problem, the step 1 to the step 6 are provided;
For easy understanding, the above description will be given first, referring to fig. 2, where the data acquisition module with the ID value of 56 belongs to the category a, the dashed frame represents the first data acquisition module before the position is changed, the solid frame represents the first data acquisition module after the position is changed, the first data acquisition module changes from the position of the dashed frame to the position of the solid frame, that is, to the vicinity of the data acquisition module with the ID value of 56, the data acquisition module with the ID value of 56 is separated from the dashed frame by two communication distances, and the new path length is reduced by one communication distance, so that, when the first data acquisition module changes to the vicinity of the data acquisition module originally separated from the data acquisition module by P communication distances, where P is greater than or equal to 2, the new path length is reduced by P-1 communication distance; referring to fig. 3, the data acquisition module with the ID value of 60 belongs to the class B, the dashed frame represents the first data acquisition module before the position is changed, the solid frame represents the first data acquisition module after the position is changed, the first data acquisition module is changed from the position of the dashed frame to the position of the solid frame, that is, to the vicinity of the data acquisition module with the ID value of 60, and the data acquisition module with the ID value of 60 is the adjacent data acquisition module originally separated from the dashed frame by two communication distances, at this time, the new path length is unchanged; referring to fig. 4, the data acquisition module with an ID value of 62 belongs to a class C, the dashed frame represents the first data acquisition module before the position is changed, the solid frame represents the first data acquisition module after the position is changed, the first data acquisition module is changed from the position of the dashed frame to the position of the solid frame, that is, to the vicinity of the data acquisition module with an ID value of 62, the data acquisition module with an ID value of 62 is an adjacent data acquisition module originally separated from the dashed frame by a communication distance, and the new path length is increased by a communication distance.
Then explaining the above step 1 to step 6, in step 1, because the transmission path before the position of the first data acquisition module is changed is repeatedly executed to generate a new transmission path, which may complicate the transmission path, so the first data acquisition module sets the flag value to zero and sets the flag value threshold in advance, in step 2, the first data acquisition module sends the first request information to the data acquisition modules other than itself, after receiving the first request information, the data acquisition module sends the first reply information to the first data acquisition module, the first reply information includes the ID value of the data acquisition module, and the ID value of the other data acquisition module adjacent to the data acquisition module, adjacent means that a communication distance is separated, through step 2, the first data acquisition module can grasp the positional relationship between all data acquisition modules, in step 3, if the position of the first data acquisition module does not change, end all steps, otherwise, the first data acquisition module sends the second request information to the adjacent data acquisition module, after receiving the first request information, the first reply information includes the ID value of the first data acquisition module, and when the first data acquisition module is in combination with the first reply information, the first reply information is higher than the second data acquisition module, the first data acquisition module can reply the first data acquisition module, the adjacent data acquisition module can grasp the positional relationship between all data acquisition modules, in a higher priority, if the first data acquisition module has a priority, and a priority is a priority, in step 4, if the adjacent data acquisition module belongs to the class D, the transmission path of the monitoring data to the first data acquisition module is regenerated, the flag value is set to zero, step 2 is skipped, in step 5, if the adjacent data acquisition module does not belong to the class D, it is judged whether the flag value is greater than the flag value threshold, if so, the transmission path of the monitoring data regenerated to the first data acquisition module is regenerated, the flag value is set to zero, step 2 is skipped, since the transmission path has become too complicated at this time, the transmission path should be regenerated, in step 6, if the flag value is less than or equal to the flag value threshold, the transmission path of the monitoring data to the first data acquisition module before the position of the first data acquisition module is changed, and the determined class of the adjacent data acquisition module, a new transmission path of the monitoring data to the first data acquisition module is generated using a corresponding method, the flag value is accumulated, step 2 is skipped, wherein the adjacent data acquisition module belongs to the class a and accumulates 0, the adjacent data acquisition module belongs to the class B and the adjacent data acquisition module belongs to the accumulated class C2.
