System Overview:
Equipment inspections mainly rely on inspection personnel to conduct manual inspections on a regular basis. Due to the constraints of climatic conditions, environmental factors, personnel quality and sense of responsibility and other factors, the inspection quality and in-place rate cannot be guaranteed. At the same time, there is no timely feedback on the information reflecting the operating status and equipment defects, and the hidden dangers of the equipment cannot be discovered in time, which leads to equipment failures. In addition, it is difficult to effectively supervise inspectors using traditional inspection management methods, and equipment accidents caused by improper inspections are not uncommon. Therefore, in order to ensure the smooth progress of line and equipment inspections and reduce unnecessary economic losses, the call for reforming the traditional backward inspection methods is getting higher and higher. How to supervise the in-place situation and working status of the patrol inspection route and the standardized management of the patrol inspection work has become a common concern and urgent problem to be solved by power grid managers.
system structure
The system hardware architecture includes: fixed readers, antennas, RFID handheld devices, tags and servers;
Data exchange method: It can be implemented in two ways:
Online data exchange, real-time transmission of field data back to the background information system for processing and analysis through a fixed reader
Offline data exchange, after collecting the data in the field through the handheld device, import it to the back-end information system for processing and analysis
Warehouse Management-In and Out of Warehouse
A fixed reader is installed at the entrance of the warehouse, and the information will be read in real time when the carrier frequency card enters and exits the warehouse.
RFID tags are attached to fixed shelves and products in the warehouse.
Warehouse management-inventory and inventory
Find goods (pick up) enter the ID of the goods you want to find in advance, and then find the goods according to the system instructions.
Inventory pre-load the list of goods to be counted, and then perform the inventory operation according to the system instructions.
Computer room management
Anti-metal tag
This solution uses the most popular non-contact IC card, which is a chip card that can read and write information without physical contact. The instant energy required to read and write information is provided by the reader, and the sensing distance is 0~3M. Because the card has a multi-purpose function. Compared with traditional card technology, it has the following advantages:
Long service life and low maintenance cost;
Easy to use, long reading distance;
Safe and reliable;
One card for multiple purposes;
Enhance the image of the government and enterprises;
Better performance-price ratio;
System Features:
The system is composed of four parts: the master station system, PDA, CF RFID reader card and RFID electronic tags attached to the equipment. The system adopts advanced and mature computer technology, wireless communication and bar code recognition technology, combined with the standardized inspection of the substation, to minimize the problems of missed inspections and inadequate inspections.
The architecture of the mobile inspection system adopts advanced technology to realize supervision in place. Utilizing the most advanced identification technology-RFID radio frequency identification technology, it is convenient to read RFID electronic label information through a portable data collector (PDA + reader card), which perfectly solves the supervision in place.
1. The system supports inspection services for multiple sites. Support the inspection work of various forms of substations such as centralized control stations and individual stations to meet the inspection requirements of different situations.
2. Customizable and standardized inspection routes and inspection items can meet different types of inspection requirements.
3. The scientific and reasonable patrol inspection business library design and project supervision effectively improve the quality of patrol inspection work and ensure the standardization, standardization and informationization of patrol inspection content and results.
4. The standard defect library and process-based management ideas are convenient for inspectors to identify defects and further improve defect management.
Comprehensive use of a variety of technical means to make the mobile inspection system have strong vitality and application prospects, such as portable handheld terminals, wireless communications, etc.
