Normalize the description of defects and reduce misunderstandings at work. Timely upload data can reduce the time difference due to the traditional manual form, and improve productivity. It also provides an effective means to ensure the safe operation of the power grid, improve the level of power supply, power management automation and work efficiency, and improve the benefits and benefits.
The current status quo
How to effectively improve the quality of inspection work? How to effectively informatize inspection data? How to eliminate the safety hazards during the inspection work? These problems have plagued the inspection department for many years.
Current inspection work is facing problems
1The management of defect inspection has always been the difficulty of inspection department. The situation and defect statistics in place are the main problems in the management of defect inspection.
2The problemof inspection rate and inspection quality monitoring brought about by the development of the power grid and the increase of unattended substations are becoming more and more prominent.
3, substationregular inspection lack of focus, especially for critical line sections and substations vulnerable to damage
4The level of knowledge of the patrol personnel is uneven, in the field only by experience, there is no convenient standard can be referenced in the field。
5, patrol equipment wide-ranging large, patrol line personnel sense of responsibility has good and poor.“Are the line personnel in place? Is the defect grading accurate? How is the defect description quantified?”issues such as the inability to verify
6, the inspection report is varied, the description of the same defect is not uniform, so that the higher level of management can not judge the category of defects, more can not arrange to deal with
7The number of defect reports in the four-day inspection cycle is very large, accompanied by duplicate reporting defects, can not be classified by manpower, nor can it provide a scientific basis for eliminating defects
8, manual transcription of defect records makes the workload huge, the efficiency of defect inspection is reduced, and the defect report is not easy to keep
9, manual paper recording method, in the complicated data statistics, but also because of low efficiency, cumbersome is not conducive to the actual work
10, there are many categories of production management systems, but there is a lack of effective means to integrate all the data
Third, the characteristics of the system:
1, standardized inspection workflow and defect description of the integration of another inspection work more accurate and efficient;
2, the introduction of cloud computing, cloud storage technology, the establishment of inspection system cloud service platform.
3, the realization of group management, sub-level authority management scheme to achieve the unified management scheduling of the hierarchical department.
4, the use of GPS and information button to identify the double inspection mode, inspection area is not in the blind area, patrol mode flexibility is higher.
5, increase the equipment inspection project, submit equipment inspection parameters, real-time control of the operation of the equipment.
6, integrationGISGIS, the equipment resources of inspection into the system, the accurate management of equipment resources.
7, effectively ensure that inspectors inspection in place, improve the safety and reliability of equipment and lines, eliminate security risks;
8、The information management of line inspection is realized by using wireless network and mobile database technology. Reducing the overall work link, to avoid unnecessary errors, we according to the substation equipment inspection operation guidance, inspection procedures, combined with many years of mobile equipment program development experience, the inspection procedures and inspection work instructions integrated in the substation equipment
Inspection system, standardized the description of defect records, designed substation equipment inspection system in accordance with the inspection department's workflow at the same time, improve efficiency, strengthen the management of personnel in place, improve the entire inspection work of information, paperless.
Fourth, the working principle and function of the system
1How it works
Inspector will automatically receive the task and results of real-time reporting, inspection only need to carry the inspector according to the inspection plan, inspection time to reach the designated inspection point inspection can be. Use the inspector to distance the patrol point when you reach the inspection position3-6mmMake a read point(Read RF points or scan QR codes/Bar code), after reading, there will be Chinese voice broadcast the inspection point device name, and pop up the equipment needs to inspect the content (if the device exists the content of the inspection required), according to the operating instructions and requirements of the device in turn to check the device (e.g.1The main transformer needs to be checked:aSwitch body: check the split gate indicator indicates correct, the sound is normal;bProtection device: the protection device power supply is normal;cIsolation switch: good contact, observe the connector for heat;dCable out: cable connector contact is good, observe the cable connector for heat and discharge phenomenon, etc., and enter the actual operating status and parameters of the equipment, or select the appropriate classification (normal/Abnormal, good/fever), submit it. If the device exceeds the standard, the abnormal monitoring center will automatically trigger the fault alarm.
Discover the equipment hidden dangers, failures can be taken, video, text description, the creation of repair work orders and other ways to the site equipment abnormal situation of visual data collection and timely feedback to the monitoring command center. All inspection data will be passed throughGPRSOrWIFIAutomaticsent to the management platform system of the monitoring center. The visual inspection management system of the monitoring center will automatically process, analyze, statistics and make reports of inspection data, facilitate the rate of inspection personnel in place, view equipment operation and parameters, inspection task assessment, improve the efficiency of work, and provide managers and users with a scientific and accurate inspection information and query basis.
