And according to the message data which is sent to the control end by the power station equipment and subjected to protocol conversion, the running state of the power station equipment and the message data display are correspondingly restored in the three-dimensional scene. When a worker clicks an image of a certain device in the three-dimensional scene, relevant information and monitoring data currently extracted from the message content after protocol conversion are displayed on a monitoring screen.

For example: when a worker clicks a camera in a three-dimensional scene, the picture in the current camera lens can be displayed, the error fields occur in the protocol conversion process, and the error information represented by the error information is positioned by judging which protocol fields in the electric power instrument are not successfully converted. And through operating the button outside the picture, can click this camera of various buttons remote control and shoot, make a video recording, analyze debug and confirm, and actions such as conversion angle.
And 104, fusing the video monitoring data with the instrument protocol conversion data to realize real-time management of positioning.
In order to quickly respond to various conditions of a power station, the working efficiency is improved, and the field management level of the power station needs to be improved; meanwhile, the capability of personnel safety and operation safety is ensured by improving the personnel real-time management and scheduling. Through the video monitoring fusion satellite positioning technology, the position distribution of the instrument of the power station can be accurately and rapidly mastered under the three-dimensional live-action. According to the analysis result of the analysis model on the power station message data, the conditions of various devices on the current site of the power station are mastered in real time, and basis is provided for work arrangement, work supervision and safety reminding of related staff.
And (3) high-precision positioning and controlling of the position of the instrument.

And combining the video monitoring images to display the accurate distribution of each instrument and the information of each instrument-associated instrument in real time in the three-dimensional live-action. The system calculates accident conditions and solutions according to the data extracted from the messages after protocol conversion and the analysis model, so that not only can the on-site meters be effectively managed, but also the error probability judgment can be carried out on the related possible meters. For example, when it is determined that an electric power meter associated with a high-voltage electric power meter is wrong in the protocol conversion process, it may be determined that other four meters associated with the electric power meter may have a risk of being wrong. One of the meters is a meter with high voltage, and the flow of the inspection meter can be planned, for example, the non-high voltage meter associated with the meter is tested first, and the inspection of the high voltage meter is not needed if the associated meter is wrong. The percent safety of workers is guaranteed. The high-voltage electrical meter is checked again when it is really necessary. And the operation route and process of the staff provide prompt functions such as safety prompt and dangerous operation warning, and the personal safety of the staff is ensured. For example: when the analysis model judges that a certain transformer is damaged according to a monitoring message of the transformer of a certain power station, a control end system changes an image of the transformer into a fault state in a three-dimensional real scene of the power station; the system prepares the working personnel in the latest idle state for processing according to personnel distribution and personnel working conditions; and according to the message information analysis, the accident cause of the transformer damage is obtained, and workers are automatically reminded of normal operation and careful electric shock during the process that the workers pass through the construction area and the workers are maintained.
And 105, intelligently allocating the inspection robot or staff to solve the problems according to the protocol message information.
The protocol conversion field carries error information and associated meter information. Such as the field data block length of meter a, the protocol conversion process is monitored for imperfections. It can be judged that two situations, namely the current conversion equipment has problems, and the current conversion equipment has problems, or the sent message has problems, so that the conversion of the defective protocol message can also cause problems, but the problem positioning is that the problem may exist in the process of transmitting the message content to the instrument B of the instrument A. From the content returned by the analysis system, the desired solution can be located. Remote operation is carried out respectively, and the intelligent dispatching inspection robot and staff solve the problem. According to the implementation flow of the solution of the analysis system, field operation is not needed, equipment overhaul and adjustment flow can be controlled remotely, a control end directly sends instructions, the instructions are converted into corresponding command messages according to the power specifications of various equipment, and the equipment receives the messages and then performs corresponding operation according to the content.
When the inspection robot in a waiting state with the nearest working intelligent allocation distance which needs to be operated on site is processed; the method can help analyze how many people need to be dispatched for maintenance according to the severity of message display. For example, when it is determined that there is a problem in the message of the meter B, and in fact, because the meter C also has a problem, prediction and early warning of related staff can be provided for a plurality of meter repairs, respectively. Notifying the staff of the relevant responsible area for processing. For example: according to the solution of the fault of the power station equipment in the thunderstorm days returned by the analysis system, a plurality of power meter protocol conversions all generate content errors, and the errors can be generated on which meter according to which fields the error fields of the protocol conversions belong to and on which meter the errors are generated, and the meter is related to the position where the meter is distributed; some simple instrument errors represent that the required operation can be finished by a patrol robot, such as closing or opening a certain electric switch for overhauling; the maintenance and replacement of the equipment such as the high-voltage circuit breaker with the fault represented by the field error is distributed to the responsible person closest to the area according to the position and the working state of the responsible area of the staff; in addition, the inspection frequency and the route location of the inspection robot are properly increased for the high-fault area of the instrument.
And 106, optimizing the power station according to the inspection and maintenance data.
After maintenance is finished, various electric equipment resends messages to the control end, the intelligent inspection robot and staff send inspection and maintenance data records to the control end, and after the electric messages are converted and extracted through protocols, the analysis system aggregates historical data and current message data, and various possible problems are analyzed and optimized.
