Preface
With the development of new technologies, especially the continuous advancement of RFID Internet of Things technology and GIS geographic information technology, new technical methods have been provided for asset and inventory management. According to GEA plate heat exchanger industry assets and inventory types, wide distribution, rapid inventory changes, complex inventory characteristics, this program uses the latest RFID Internet of Things technology and GIS geographic information technology to achieve effective management and control of assets and inventory. This solution can achieve transparency and consistency of assets, inventory and financial data, greatly simplifying a large number of data assets and data inventory processes.
Project Objectives The expected goals of this program are as follows:
Asset and inventory standardization
All assets and inventories are uniformly issued with electronic tags to record asset and inventory information and other key information. Asset and inventory management visualize all assets and inventory in the RFID tag and the back-end to write the address location to be stored, and the location enters the GIS system. All assets and inventory data can be viewed in real time in the GIS system. Assets and inventory inspections facilitate the use of RFID handsets to remotely inspect equipment in various warehouses, offices, and other locations, read asset data, and quickly check asset status and compare it with the GIS background.
Real-time monitoring of valuable assets and inventory
All key outlets are equipped with RFID readers, and real-time alarms will be issued when assets or inventory moved without authorization are moved. The overall plan This plan consists of an RFID tag system, a GIS asset and inventory management system, and a short message warning system. Among them, RFID tags are used for asset inventory tags to store inventory information. The GIS management system realizes the implementation management and display of assets and inventory.
1.1 Overall system process
1) Assets and inventory warehousing. When assets and inventory are warehousing, the asset management office (section) or warehouse management office enters asset information and asset use address information into the electronic label, and then pastes the electronic label to the asset in accordance with the specifications. In stock. At the same time, asset or inventory information will enter the background GIS system. The GIS system can display real-time asset and inventory information in various offices, departments, and warehouses.
2) Monitoring of valuable assets and inventory accessories. Common assets use UHF passive tags with a reading distance of 4-8 meters, and the price is lower. Use active electronic tags with a reading distance of 80-120 meters for valuable assets and inventory.
3) Asset and inventory inspection companies and warehouse managers are equipped with handheld inspection equipment, and they only need to walk around the office or warehouse to complete the inspection. At the same time, the handheld device can be connected to the GIS server through GPRS, and upload the identification data and the inventory data to the server to complete the inventory. At the same time, the GIS system generates a new location report and compares it with the original registration data to determine the inventory or asset transformation and generate the report.
1.2 System components
The system composition mainly includes the following parts: the reader realizes the real-time automatic collection of remote data, the recognition distance can reach 80-120 meters, and the main purpose is to identify inventory tags. Electronic tag UHF tag: The identification distance is 4-8 meters, and it is pasted on non-precious assets. According to different assets, different packaging modes can be provided, such as flexible tags, standard tags, anti-metal tags, etc. Active RFID tags: Recognizable distance of 80-120 meters, mainly to provide real-time inventory of warehouses. Different packaging modes can also be provided, such as flexible labels, standard labels, anti-metal labels, etc. Depending on the size of the label, the longest use time can reach 3-5 years, and it can be used repeatedly, which is environmentally friendly and also greatly saves the cost of buying labels. The card issuer writes data for the electronic tag, such as asset or inventory name, model, barcode number, etc., and can set a password, lock the data area, and prevent the data in the electronic tag from being rewritten. The handheld is used for 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. Card-issuing software is mainly used to write data into electronic labels, including device name, device model, device barcode, etc. After writing the data, it can automatically generate reports and import them into the GIS system server. GIS platform GIS asset management auxiliary system and RFID middleware platform based on RFID technology. The company map is vectorized according to the floor plan of the office or warehouse, and all the information of assets and inventory can be displayed on the map in real time.
2. Detailed design
2.1 Assets and inventory are newly added. Install a card issuer at the asset or warehouse management office.
When new assets or inventory arrive at the company, use the card issuing software to set the electronic label data. The data includes information such as nature, model, specification, and storage location. After completing the label information, attach the electronic label to the corresponding product. At the same time, the asset information (asset storage address such as the office on the 2nd floor or the fourth shelf of the warehouse 3, etc.) is submitted to the GIS database, and the GIS database displays the location on the map.
Assets and inventory allocation When assets are allocated, use the handheld to read the asset tag and change the address information in the tag. Confirm that the upper handheld computer uploads the modified data to the GIS server, and the GIS server can display the new location of the asset.
When assets and inventory are scrapped, when scrapping assets, use the handheld to mark the asset as scrapped. Or it can be scrapped automatically according to the preset useful life of the asset tag.
Asset repair For assets that require replacement parts, the parts and repair information of the tag can be pre-written in the asset tag.When repairs are needed, you can use the handheld to update the information of a certain part in the label
Assets and inventory check Assets and inventory check personnel hold handheld computers, start the inventory software, and patrol the offices and warehouses that need to be counted. After the patrol is completed, the asset inventory will be automatically completed.
Valuable assets and inventory monitoring Deploy active readers in key locations to monitor valuable assets and inventory in real time. When valuable assets or inventory accessories are illegally handled or moved, the reader transmits the data to the GIS system and SMS system. The GIS system can display the location of illegal transport in real time. The SMS system can alarm immediately.
