【System Overview】
As a bridge between the physical world and the existing IT system, RFID technology can effectively integrate the daily management activities of power assets with the power asset management system with the help of GPRS wireless remote transmission function, so as to achieve real-time synchronization of physical information and system information. . Therefore, it has become possible to establish a power asset management system based on RFID technology to realize automatic management.
This time, it is mainly a combined power asset management module, which collects power asset data in related power assets. By attaching electronic tags to devices such as power assets and equipment, data read and write information storage. The inspection is carried out by means of GPRS communication, and the data is transmitted, and the data interface program is directly developed and entered into the system.
【System composition】
(1) Handheld mobile reader:
Integrate RFID reading and writing module, gprs wireless communication module and reader power interface board to realize the real-time automatic collection and wireless transmission of remote data, and design the workflow in the handheld reader.
Used for power asset inventory, it can quickly read the electronic tag information on the device, and send the read tag information to the background server for processing through the built-in GPRS wireless communication module.
(2) Electronic label:
Power assets in the power industry have a wide variety of different specifications and most of them are metal surfaces. Metal interference has always been a difficulty in the application of RFID technology. In order to solve the problems of metal interference and easy attachment to power assets of various specifications, a special Attached labels and tag labels for different sizes and specifications of power assets, through the special design and packaging of the built-in antenna of the label, the label has good anti-metal interference performance.
(3) Card issuing software:
It is mainly used to write data into electronic labels, including device name, device model, device barcode, etc. After the data is written, the report can be automatically generated and imported into the system server.
(4) ERP power asset management auxiliary system and RFID intermediate development kit based on RFID technology.
[Introduction to the process]
Power asset management includes operations such as the addition, allocation, idleness, scrapping, maintenance, and inventory of power assets. It includes the entire process of equipment from leaving the factory, putting into use, and scrapping. When the equipment leaves the factory, an electronic tag is installed, and the information of the power asset is written in the tag. Every time the power asset management operation is performed, the reader will read the electronic tag on the power asset and send the information to the server for processing, thereby realizing power Asset tracking management.
(1) New operation of power assets: Fill in the relevant information (site name, power asset barcode, model, name) of the equipment to be managed in the card issuance program, and save the record in the database. Attach electronic tags with power asset information (or hang on power assets) as required.
(2) Power asset transfer operation: prepare the power asset to be transferred, open the door that controls the travel switch, and the reader is in the tag-reading state at this time. Take out the electrical assets with electronic tags, and confirm that the electronic tags on the equipment are read. The GPRS wireless transmission method is transmitted to the background database to complete the allocation of power assets.
(3) Power asset maintenance operation: prepare the equipment that has failed, and put the handheld reader in the state of reading tags. Take the faulty device out, and the faulty device will be transferred away from the base station. Bring the equipment to the warehouse maintenance area, confirm that the label information on all equipment is correctly read, and the GPRS wireless transmission method is transmitted to the background database. At this time, the equipment is in maintenance status.
(4) Operation of scrapping of power assets: prepare scrapped equipment, take the scrapped equipment out, and confirm that the label is read correctly. The wireless transmission mode of GPRS is transmitted to the background database to complete the equipment scrapping operation.
(5) Power asset inventory operation: press the “I/O” switch of the handheld to turn on, and click to connect to GPRS. Start the inventory process.
[System advantages]
(1) The whole system has the characteristics of high reliability, high confidentiality, easy operation and easy expansion. The power asset identification system can operate independently and does not depend on other systems.
(2) Establish safe and reliable registered power asset files, strengthen power asset supervision through high-tech, rationally allocate resources, reduce resource waste, and prevent the loss of power assets. It can effectively and accurately identify, collect, record, and track the data information of power assets (power assets equipped with electronic tags) entering and leaving the equipment to ensure the rational use of power assets.
