[0033] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments.

[0034] Platform embodiment:

[0035] As shown in Figure 1 , the GIS data analysis and hidden danger judgment platform of the present embodiment comprises a data acquisition module, a data processing module, a data transmission module and a data display module; the output end of the data acquisition module is connected with the input end of the data processing module, the output end of the data processing module is connected with the input end of the data transmission module, and the output end of the data transmission module is connected with the input end of the data display module.

[0036] As other embodiments, the data transmission module can also be omitted, and the output end of the data processing module is directly connected with the input end of the data display module.

[0037] As shown in Figure 2As shown, the data collection module in the embodiment includes four kinds of data collectors, namely, voltage collection sensor, current collection sensor, micro-weather collection sensor and temperature collection sensor. As other embodiments, the number and kind of data collectors included in the data collection module can be set according to actual needs, for example, only voltage collection sensor and current collection sensor can be included.

[0038] As shown, Figure 3 As shown, the data processing module includes data receiving module, data conversion module, data analysis module, data calculation module, hidden danger judgment module, data feedback module, emergency warning module, hidden danger processing module and power distribution network GIS database; the output end of the data receiving module is connected with the input end of the data conversion module, the output end of the data conversion module is connected with the input end of the data analysis module, the output end of the data analysis module is connected with the input end of the data calculation module, the output end of the data calculation module is connected with the input end of the hidden danger judgment module, the output end of the hidden danger judgment module is connected with the input end of the data feedback module, the output end of the data analysis module is also connected with the input end of the emergency warning module, the emergency warning module is bidirectionally connected with the hidden danger processing module, the output end of the hidden danger judgment module is also connected with the input end of the hidden danger processing module, and the output end of the power distribution network GIS database is connected with the input end of the data analysis module.

[0039] Among them, the data in the GIS database is the data collected by continuously testing the GIS equipment, which can prevent the abnormality in the GIS equipment circuit and simulate hidden dangers.

[0040] In the embodiment, the emergency warning module is bidirectionally connected with the hidden danger processing module, thereby indirectly realizing the connection between the input end of the emergency warning module and the output end of the hidden danger judgment module; as other embodiments, if the emergency warning module is not bidirectionally connected with the hidden danger processing module, the input end of the emergency warning module can also be directly connected with the output end of the hidden danger judgment module. It is easy to know that the input end of the data receiving module is the input end of the data processing module, and the output end of the data feedback module is the output end of the data processing module.

[0041] The working principle of the GIS data analysis and hidden danger judgment platform in the embodiment will be described in detail as follows:

[0042] In the working process of the GIS data analysis and hidden danger judgment platform, the sensors in the data acquisition module are used to collect data, the data receiving module in the data processing module receives the collected data, the data conversion module is used to convert the collected data into data recognizable by the data analysis module (for example, converting the electrical signal into a digital signal), and the converted collected data is analyzed, calculated and hidden danger judged by the data analysis module, the data calculation module and the hidden danger judgment module. Finally, the data feedback module is used to feed back the hidden danger judgment result to the data display module for display, and the possible hidden dangers are prewarned and emergently handled by the emergency warning module and the hidden danger handling module.

[0043] For example, if a line has problems such as line burning or poor contact, the data acquisition module can detect the change of data in time, the data processing module converts, analyzes, calculates, judges and feeds back the collected data, the problems judged are informed by the emergency warning module, and the hidden danger handling module is used for emergency handling, so as to form the early warning of hidden dangers and the timely remedy of problems, thereby facilitating the better and faster operation of the maintenance personnel.

[0044] The data processing module realizes the process of hidden danger judgment as follows:

[0045] The data receiving module receives the voltage and current data collected by the voltage collection sensor and the current collection sensor in the data collection module and transmits the voltage and current data to the data conversion module, the data conversion module converts the collected voltage and current data into corresponding digital signals, the data analysis module compares the converted digital signals with the digital signals corresponding to the voltage and current data under normal conditions stored previously, when the converted digital signals are greater than the digital signals corresponding to the voltage and current data under normal conditions stored previously, the voltage and current data at the obstacle position in the GIS device circuit are detected by using the half detection method (as other embodiments, the half detection method can be replaced by other existing voltage and current abnormality detection methods), the obstacle position is the position of voltage and current abnormality in the GIS device circuit detected by the data analysis module through the half detection method; then the voltage and current data at the detected obstacle position are calculated by using the data calculation module, the active calculation load, the reactive calculation load and the apparent calculation load of the line at the obstacle position are calculated, then the average load of the active calculation load, the reactive calculation load and the apparent calculation load is compared with the average maximum load (the average maximum load is the average load of the active calculation load, the reactive calculation load and the apparent calculation load corresponding to the line under normal conditions), when the difference between the average load and the average maximum load exceeds the set value, it is determined that there is a hidden danger in the line, so as to realize hidden danger judgment, and the possible hidden danger is fed back to the data display module for display through the data feedback module, and the emergency warning module and the hidden danger processing module are used for warning and emergency treatment.

[0046] The load calculation formula is:

[0047]

[0048] In the formula, P ca , Q ca and S ca are the active calculation load, the reactive calculation load and the apparent calculation load of the line at the obstacle position respectively, K si is the active load simultaneous coefficient, m is the total number of connected electric equipment groups of the line at the obstacle position, K di , ∑P Ni are the demand coefficient, the power factor angle tangent value and the total equipment capacity of a certain electric equipment group respectively, I ca is the calculation current of the line at the obstacle position, and U N is the rated voltage of the line at the obstacle position.

[0049] In some cases, the data analysis module can also directly determine whether there is a hidden danger in the line according to the collected data without going through the data calculation module for calculation. For example, when the data analysis module analyzes that the temperature collected by the temperature sensor is greater than the set temperature, it is directly determined that there is a hidden danger in the line. At this time, the data analysis module directly transmits the hidden danger information to the emergency warning module for warning. In the present embodiment, the hidden dangers that can be directly determined by the data analysis module are not fed back to the data display module for display. In actual application, if you want to display such hidden dangers, you only need to connect the output end of the emergency warning module to the input end of the data feedback module.

[0050] In summary, the GIS data analysis and hidden danger judgment platform of the present embodiment utilizes the data processing module to timely process the collected data, cooperates with the data receiving module, the data conversion module, the data analysis module, the data calculation module, the hidden danger judgment module, the data feedback module, the emergency warning module, the hidden danger processing module and the power distribution network GIS database, and can not only give early warning for the hidden dangers that may occur, but also make timely response to the hidden dangers that may occur, i.e. hidden danger emergency treatment, including regional power failure, so as to speed up the timely finding of the GIS equipment circuit problem and reduce the time and economic losses. In addition, the GIS data analysis and hidden danger judgment platform of the present embodiment can also display the hidden danger situation in real time through the data display module, which is more intuitive.

[0051] In summary, the GIS data analysis and hidden danger judgment platform of the present embodiment has the following advantages:

[0052] 1) It can predict the hidden dangers that may exist in the line in advance and give early warning.

[0053] 2) There are two treatment methods for the hidden dangers that may occur, including: (1) using the hidden danger processing module for hidden danger emergency treatment, such as regional power failure; (2) informing the staff on site for treatment through warning, which ensures the safety of the line.

[0054] Method embodiment:

[0056] (1) Collecting the voltage and current data of the GIS equipment circuit and converting the collected voltage and current data into corresponding digital signals;
