Overview of inspection management system
Based on years of application development experience, Fuen Electronics successfully developed an intelligent inspection system for power transmission and substation equipment based on Pocket PC and RFID technology through cooperation with experts with rich experience in power transmission and substation operation management.
The intelligent inspection system for power transmission and substation equipment is composed of line inspection terminal and post management system. The overall structure is as follows:
The inspection terminal is a Pocket PC running Microsoft Windows Mobile. The Pocket PC is equipped with an RFID scanning device for locating the device (patrol object) and is also used for in-place tracking. The background management system provides functions such as equipment ledger management, inspection management and defect management, and accepts inspection data from the inspection terminal.
Mobile inspection business process:
System functions:
The equipment inspection management system is mainly composed of electronic tags (Tag), handheld tag reading and writing equipment and management systems. Mainly have the following functions:
1. Handheld tag reading and writing equipment
There is a small mobile database in the handheld, including detailed information and operating procedures of the outdoor equipment in the substation;
Each time the code of the tag is read, the relevant information is found from the database, and the team members record according to the on-site situation;
With the function of patrol route prompt;
Automatic reset function of patrol route;
The handheld device can record the team’s patrol route, time and record result throughout the day;
Can store one week’s patrol data.
2. Inspection management system
Equipment attribute information database;
Check the record information database;
Data exchange function with handheld device;
Database information maintenance, editing and deletion;
Check the statistical analysis of recorded information;
Equipment defect statistics;
Evaluation of inspectors’ work;
Traceability of inspection responsibilities;
Data report function
System benefits
The design goal of the intelligent inspection system for power transmission and transformation equipment is to improve the level of equipment maintenance by ensuring the quality of the inspection work and improving the efficiency of the inspection work. Specifically, the intelligent inspection system for power transmission and transformation equipment mainly solves the following three important problems in the inspection work of power transmission and transformation equipment:
1. Inadequate inspections, missed inspections, or not on time;
2. Manually filling in the inspection results is inefficient, easy to miss items or make mistakes;
3. It is difficult for managers to understand the condition of equipment in a timely, accurate and comprehensive manner, and it is difficult to formulate the best maintenance and repair plan
Hardware Design of Inspection Management System
The hardware used in this system includes a card issuer, a handheld POS machine (handheld PDA+CF interface card reader); the non-contact IC card used is a 13.56M HZ 15693 metal tag. They provide the core technical guarantee for the function realization of this system.
1. 13.56 MHZ 15693 metal label
This solution uses the 15693 card among the most popular non-contact IC cards. It is a chip card that can read and write information without physical contact. The instantaneous energy required to read and write information is provided by the reader. The sensing distance is 3~5CM. 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
* Safe and reliable
* One card for multiple uses
* Enhance the image of the government and enterprises
* Better performance and price ratio

2. Handheld POS machine
This system uses the FN HFM0318 handheld POS machine produced by Fuen Company to collect data and update equipment information during equipment inspections.
This POS machine can read and write data on smart cards that comply with the ISO/IEC15693 standard and display prompt information. With anti-collision function. The POS machine has a built-in 16Mb FLASH memory, which can be operated online or offline to ensure that it can still work in the case of computer failures and network failures, while saving network resources. Compared with similar domestic products, this product has the characteristics of compact and fashionable, stable performance, convenient operation, and perfect secondary development tools. At the same time, an optional GPRS module is provided to prepare for occasional applications that require instant data transmission.

Product Description:
FN HFD1708 is a mini CF interface high-frequency RFID reader (RFID Reader), is a portable IC card reader with superior performance, suitable for ISO 14443A, ISO15693, Mifare 1 standard 13.56MHZ high-frequency electronic tags for data Read, write, encrypt and other operations. The Compact Flash communication interface can be used on laptops, PDAs, and smart phones with CF card interfaces, easily making it a portable reader with RFID reading and writing capabilities. The reader has good reading and writing performance, stable and reliable work, fast communication speed, and compact design. The maximum volume is 43*82.5*11MM. After inserting the reader into the CF slot, only 40MM is exposed. It can be widely used in warehouse management, personnel identification, ticket management, train ticket checking, power inspection, prison management, steel cylinder management, food counterfeiting, package tracking, product quality inspection, drug management, etc. .
