On the basis of the embodiment shown in fig. 1, the power monitoring terminal 1 in this embodiment is deployed in a plurality of power distribution cabinets in a power network, where the power distribution cabinets are final-stage devices of a power distribution system, and the power distribution cabinets are mainly used for distributing electric energy of a certain circuit of a previous-stage power distribution device to nearby loads. If the power distribution cabinet breaks down, the normal work of the nearby electric equipment can be influenced.
The management mode of the existing power distribution cabinet is that maintenance personnel regularly monitor and operate and maintain equipment, and when a fault hidden trouble is found, the power distribution cabinet is maintained. In this way, the frequency of monitoring the switch board by the maintenance personnel is not too high, usually once every few days or once every few weeks, due to the limited energy of the maintenance personnel. Therefore, the power distribution cabinet is easy to break down, the affected units or individuals send help seeking information, and after receiving related information, maintenance personnel can arrive at the site to repair the power distribution cabinet. In this way, the time from the occurrence of the fault to the repair of the fault is long, and the work and life of the distribution unit or the individual in the distribution cabinet during the period can be affected little (for example, the production line of the factory can not be started).
In this embodiment, the power monitoring terminal 1 communicates with the server 3 and the mobile phone 4 through the 5G communication module, the server 3 uses the cloud server instead, and each 5G communication module has a unique 5G terminal number.
Besides the voltage sensor serving as a voltage acquisition unit, the power monitoring terminal 1 is also provided with a plurality of other acquisition units for acquiring data of the power distribution cabinet, and the data acquired by the acquisition units comprises operation data, environmental data and positioning information. Besides the voltage sensor, the acquisition unit also comprises a temperature sensor, a humidity sensor, a smoke sensor and a current sensor, and the original data information of the sensors also adopts the same processing process as the original voltage data information.
The server is provided with a storage unit 31, a processing unit 32 and a statistical analysis unit 33. The storage unit 31 stores therein a plan library of maintenance plans. The storage unit 31 also stores address information of the power distribution cabinets corresponding to the power monitoring terminals 1. The processing unit 32 is configured to analyze the data acquired by the acquisition unit, generate an abnormal type when the analysis result is that there is an abnormality, match a corresponding maintenance scheme in the storage unit 31 according to the abnormal type and the abnormal data, and send a maintenance signal, where the maintenance signal includes the abnormal type and the maintenance scheme.
In this embodiment, each mobile phone of the maintenance personnel has a unique 5G terminal number, and the mobile phone 4 further includes an alarm unit 41 and a positioning unit 42. The alarm unit 41 is used for receiving maintenance signals; when receiving the maintenance signal, the alarm unit 41 sends out a prompt of voice and text. The positioning unit 42 is used for acquiring positioning information of the maintenance end.
When the processing unit 32 sends the maintenance signal, the signal is sent to the mobile phone of the maintainer nearest to the abnormal power distribution cabinet. The storage unit 31 is further configured to perform exception storage, and specifically, when the storage unit 31 stores an exception, the storage unit stores the exception according to the exception type, the detection time, the 5G terminal number of the 5G communication module corresponding to the power monitoring terminal, and the mobile phone 5G terminal number of the person performing maintenance. The statistical analysis unit is used for performing statistical analysis on the abnormity. When the statistic analysis unit carries out anomaly statistic analysis, recurrence rates of various anomaly types are generated, if the recurrence rate of a certain anomaly type is greater than X, a scheme updating signal is generated, and the scheme updating signal comprises the anomaly type and a corresponding recurrence rate; and if the abnormal recurrence rate of the power distribution cabinet maintained by a certain maintenance end is greater than Y, generating a personnel training signal, wherein the personnel training signal comprises the 5G terminal number of the mobile phone and the corresponding abnormal recurrence rate. The specific values of X and Y can be set by those skilled in the art according to the historical statistics of the abnormal recurrence rate.
For convenience of explanation, it is assumed in this embodiment that there are 200 power distribution cabinets, 200 power monitoring terminals, and 10 maintenance terminals in the system. The specific implementation process is as follows.
200 electric power monitor terminals 1 respectively with the switch board one-to-one carry out data acquisition, the data of gathering include the operational data and the environmental data of switch board to send the data of gathering for server 3. After the server 3 receives the data sent by each power monitoring terminal 1, the processing unit 32 analyzes the collected data of each power monitoring terminal. And when the analysis result shows that the abnormal condition (such as over-high temperature) exists, generating an abnormal type, and matching a corresponding maintenance scheme in the storage unit according to the abnormal type and the abnormal data.
The processing unit 32 matches address information of a corresponding power distribution cabinet in the storage unit 31 according to the 5G terminal number of the 5G communication module corresponding to the power monitoring terminal with abnormal data, calculates the distance between the mobile phone of each maintainer and the power distribution cabinet with abnormality according to the positioning information fed back by the mobile phone of each maintainer, and sends an overhaul signal to the mobile phone of the maintainer closest to the abnormal power distribution cabinet. After the maintenance signal is received by the alarm unit of the mobile phone of the maintenance personnel, a reminder is sent out in a mode of voice (for example, "please note, you receive a new task |) and characters. The power distribution cabinet is reminded of the maintainers that the power distribution cabinet is abnormal and needs to be overhauled and maintained, the maintainers can shorten the preparation time due to the fact that the overhauling signals comprise abnormal types and maintenance schemes, the preparation work can be more targeted, and the power distribution cabinet can be overhauled and maintained as soon as possible after the power distribution cabinet reaches the position.
When the storage unit 31 stores the abnormality, the abnormality is stored according to the abnormality type, the detection time, the 5G terminal number corresponding to the power monitoring terminal, and the mobile phone 5G terminal number of the maintenance person who performs maintenance. Then, the statistical analysis unit 33 is configured to perform statistical analysis on the anomaly to generate recurrence rates of different anomaly types, and if the recurrence rate of a certain anomaly type is greater than X, generate a scheme update signal, where the scheme update signal includes the anomaly type and a corresponding recurrence rate. The maintenance personnel use the maintenance scheme in the maintenance signal as a guide scheme to carry out maintenance. If the recurrence rate of a certain abnormal type is greater than X, the maintenance scheme of the abnormal type in the plan library needs to be optimized, so that a scheme updating signal is sent out to remind a manager of the server to optimize the maintenance scheme of the abnormal type in the plan library. And if the abnormal recurrence rate of the power distribution cabinet maintained by a certain maintainer is greater than Y, generating a staff training signal, wherein the staff training signal comprises the 5G terminal number of the mobile phone of the maintainer and the corresponding abnormal recurrence rate. Each maintenance person has its own handset. When the statistic analysis unit carries out anomaly statistic analysis, if the anomaly recurrence rate of the power distribution cabinet maintained by a certain maintainer is greater than Y, the maintenance capability of the maintainer needs to be improved, and therefore a personnel training signal is generated. The personnel training signal comprises a 5G terminal number of the mobile phone of the maintainer and the corresponding abnormal recurrence rate, so that the manager can know the specific situation in time. Compared with the prior art, by using the system, when the power distribution cabinet has fault hidden danger, maintenance personnel can timely know the condition and maintain the power distribution cabinet as soon as possible, and the condition of influence on the power distribution cabinet due to faults of the power distribution cabinet is reduced as much as possible.
Optionally, the mobile phone of the maintenance staff further includes a status unit, configured to mark a working status of the maintenance staff, where the working status includes task in progress and waiting in progress.
And when the processing unit sends the maintenance signal, the processing unit sends the maintenance signal to a mobile phone of a maintainer which is waiting and is closest to the abnormal power distribution cabinet in working state. When the maintenance signal is sent, the maintainer closest to the power distribution cabinet with the abnormality is possibly in a task state, and at this time, even if the maintenance signal is sent to the maintainer, the maintainer cannot go to the power distribution cabinet in the maintenance signal to maintain and repair the power distribution cabinet. And the mobile phone which is sent to the maintainer whose working state is waiting and is nearest to the abnormal power distribution cabinet avoids the situation, and the processing unit can find the maintainer which is nearest to the processing unit in the waiting state, so that the maintainer can timely arrive at the site to maintain and repair the power distribution cabinet.
