2. The system has the following business functions, including the storage, movement, outgoing, inventory, distribution, inventory, and anti-theft of anti-disaster and emergency materials. The goal of the system design is to realize the automation of various management processes and facilitate the management of statistics, inquiries and Grasp the real-time status and usage of disaster relief materials.


3. The system has various functions such as statistics, analysis, and data reporting;


4. The system has the authority for hierarchical management of disaster relief materials. Managers with different permissions can flexibly configure their management function modules.



Project difficulties


1. The project implementation environment is complex, RFID tags are easily interfered by various signals such as metals, and there are many products with metal materials such as hammers, lifeboats, motors and so on in disaster relief materials.


2. The sensitivity of the chip is one of the key elements for the smooth operation of the entire RFID process. If the sensitivity of the selected chip is not high, there will be missed readings when items are read in and out, resulting in inaccurate warehouse data. Check It's troublesome.


3. There are many types of items, and the ways of entering and exiting the warehouse cannot be unified, which will have a certain impact on the reading.


4. The RFID access door reader/writer manages the entry and exit of materials, which requires extremely high equipment work efficiency, which must be fast and accurate, and the accuracy rate must reach more than 99.99%.


5. The RFID handheld device locks the reading range when searching for items, which requires accurate and error-free reading. In addition, the equipment is required to be able to move flexibly in various regions to deploy and use inventory to find materials.


6. Data is connected to the cloud platform, and the system interacts with other systems of the cloud platform.



RFID solution introduction


The RFID-based disaster relief material management system is composed of RFID access control system, RFID fixed reader, RFID handset, RFID application server, RFID management host, etc. RFID fixed readers can realize remote automatic identification of in and out of the warehouse management, RFID handhelds can realize manual inventory, the system is used for warehouse materials in and out of the warehouse, early warning, handhelds are mainly used for warehouse material inventory, can also realize materials in storage , Inventory, outbound, and alarm status query.


The system establishes an electronic file for each of the hundreds of thousands of anti-disaster and rescue materials, and manages the entire life cycle of the materials, and each material is bound with an RFID electronic tag. The system adopts the CS architecture, through the client to coordinate the management of the materials of the various disaster relief material sub-sites under its jurisdiction, and the entry and exit of each material needs to be operated through the system to ensure that the accounts are consistent.


In daily material management work, managers can use mobile RFID handsets to perform various operations such as inventory, query, outbound, warehousing, transfer, data modification, and scrapping of materials through mobile RFID handsets. The data can be real-time and cloud database via WIFI, 4G Keep in sync; RFID access doors are installed at each site to prevent illegal movement of items by detecting the authorization status in the database. If the movement of materials is detected without authorization outside the plan, the system will give an alarm and move the video equipment in parallel. On-site inspection. Managers can monitor all operations in the system in real time through the mobile APP, and provide a basis for management decision-making through data statistics and analysis functions.


01. Warehousing process


After purchasing the anti-disaster and rescue materials, first enter the relevant data into the system, define the rfid tag information through the tag reader, bind the relevant material information content, and store it in the back-end database, and then the warehouse manager will paste the corresponding items on the corresponding items according to the actual situation. RFID tags: When entering the warehouse, the rfid reader/writer installed at the entrance of the warehouse reads the rfid tag information, and after verifying that the read cargo information is correct, it is transferred to the back-end management system database.


02. Outgoing process


The disaster relief and emergency command department submits material applications to the system, and warehouse managers in various places establish an outbound order in the system based on the material list of the required department, and the warehouse managers get the corresponding goods. When leaving the warehouse, the reader installed at the exit of the warehouse reads the RFID tag information, and after verifying that the read cargo information is correct, it is transferred to the back-end management system database. After verification by the material management personnel, the warehouse is verified and confirmed.


03, RFID handheld machine inventory and search


For some conventional material warehouses, we can take inventory through the handheld computer. First, place an inventory order through the system, for example, the computer host, select this order on the handheld APP, and then scan the corresponding item label in the warehouse. , The inventory results are compared with the data information, and the back-end database is verified to be correct, and the inventory information is updated. To find a specific item, we only need to enter the item number and scan it in the warehouse. When the item is near, the signal on the device will be enhanced, indicating that it is very close to the item.


04. Exception handling (alarm and scrap reminder)


When the warehouse does not carry out outbound and inbound operations, please click the Turn on equipment monitoring button to monitor the state, and the software must remain open. The abnormal records generated by the monitoring will be generated in the asset abnormal records (displayed in red). And there will be a voice prompt for the name of the abnormal asset. If you don't want to use voice prompts and need to handle exceptions, there will be no voice prompts after processing the abnormal data.



Project operation effect
