Four, equipment tool RFID system application description

This program describes the major links of equipment installation, electronic label issuance, daily management of equipment and tools, inventory of equipment and tools, and system integration.

1. Equipment installation

The specific process is as follows:

1. Set the equipment and tool placement area inside the factory, and each area proposes unique access requirements and names in the system;

2. Install an ISO18000-6C anti-metal electronic tag in a suitable position on the tool side of each equipment, write the equipment tool information and initial information such as the operating area into the electronic tag. At the same time, the electronic tag itself has a globally unique ID number ;

3. Incorporate into the company’s local area network through the wiring project, install readers and antennas in a single channel (one reader with two antennas) or one in and one out channel (one reader with four antennas) in the area Equipment to automatically collect information;

2. Label issuance production link

The specific process is as follows:

1. The card issuer and the system are integrated and connected normally;

2. New electronic label initialization information, such as designated equipment tool data information, attribution department, responsible person, equipment materials and other information;

3. The old electronic label rewrites or resets the information, and uses the card issuer to connect to the system for information change and maintenance;

4. The finished electronic label is fixed to the safe position of the equipment tool through the screw holes at both ends;

5. The equipment tool enters the designated position area, the system automatically recognizes it, and compares the consistency with the initialization information, otherwise it will give an alarm.

3. Daily management of equipment and tools

The application diagram is as follows:

The specific process is as follows:

1. Purchase or make new equipment tools, such as equipment tools 1-10 as shown above, issue the card to initialize the electronic label and install it in a suitable position of the equipment tool as a unique identification;

2. Equipment tool entry and exit system management, 1-10 equipment tools equipped with electronic tags enter and exit the area equipped with readers and antennas, automatically read the identity and location of the equipment tool, and list it in the system equipment tool entry and exit status table, system Automatically record the in and out time of each ID identity equipment tool;

3. Equipment tool status management, when equipment tools are installed and retrieved, they can be written in the requisition information and quantity through the PC terminal or mobile collection terminal, uploaded to the server system in real time, and the equipment tool operation and idle status can be inquired in real time through the equipment tool kanban dispatching system;

4. Equipment tool monitoring and scheduling management, any equipment tool in the background system defaults to work in the specified area, such as: equipment tools 1, 2, 3, 4, 5, 6 work in area A, equipment tools 7, 8 in B, 9.10 Work in area C, etc. If there are equipment tools entering and exiting the designated parking area through the channel, the system will read the electronic tags of the corresponding equipment tools and pass the relevant information to the system for comparison. The abnormal information of the equipment tool passing this section of road will be automatically sent to the leader of the department to which the equipment tool belongs. The equipment tool that is dispatched or taken must enter the area specified by the dispatcher within the specified time through the intersection specified by the dispatcher. Otherwise, the system will also email the abnormal situation to the relevant department leaders.

5. Equipment tool maintenance and scrap management. When equipment tools need to be repaired, the maintenance logo, maintenance person responsible, time and other information are written through the electronic label to facilitate the query and deployment management of the equipment tool status. When the equipment is scrapped, the scrap mark is written. Incorporate into equipment tool scheduling and use, electronic tags can be removed and erased information for reuse.

6. Daily information query and inventory management of equipment tools, through the handheld mobile collector for equipment tool information query and inventory operations, scan the equipment tool electronic tags, you can display the equipment tool file information and related data, through the collector system inventory function For inventory, you can quickly read equipment tool data, and immediately issue inventory reports.

4. System integration management

1. Collection terminal integration and interface: develop a terminal collection system through the system platform, following the international communication protocol;

2. Reader integration and interface: The air interface for interactive operation between tags and readers adopts a unified global standardization application ISO standard.

3. Information system scalability: The system will adopt modular and component-based design methods, and strive to achieve complete independence between various businesses. All businesses are built on core components, and the communication between modules uses interfaces . Fully consider the compatibility of the internal interface and external interface of the system to adapt to the access to the tooling management system and future changes in demand.

Six, RFID equipment selection

1. Card Issuer

The UHF desktop RFID reader is developed based on ThingMagic’s international award-winning RFID module—the cost-effective M5e-C. It has the advantages of small size, stable and reliable reading and writing tags, and strong anti-collision capabilities. It is especially suitable for card issuers and medium Applications requiring distance reading and writing.

2. Fixed reader

Reader series products include serial ports, USB, built-in antennas, external antennas, network RFID readers and other combination products for users to choose. Comply with ISO 18000-6C (EPC C1G2) standard, and its working frequency is 902～928MHz/920 ~925MHz, excellent reading and writing performance, using intensive reading mode, is a high-performance reader, especially suitable for large-scale batch networking applications, can be widely used in logistics tracking, asset management, supply chain management and other fields.

The network RFID reader/writer has an exquisite appearance and has 2 antenna ports. The number of connected antennas can be selected independently, and the antennas can be flexibly connected to form a scanning channel. The reader is optically isolated universal I/O interface, which can directly drive a variety of external devices to ensure that the signal that triggers the reading action is accurately received in an environment with greater interference. The network RFID reader has the expansion capability of multi-protocol support.

3. Fixed antenna

The fixed antenna is mainly used in the radio frequency identification system of 902～928MHz. The center frequency is 915MHz. It can be directly connected to the reader through a coaxial cable. It is small in size and easy to install. It can be well matched with the coaxial cable and has a good performance. Directionality. Circular polarization of the antenna Two spatially orthogonal linearly polarized waves with equal amplitude can be combined into a circularly polarized wave. The circularly polarized waves can be divided into left-handed and right-handed circularly polarized waves according to the direction of electric field rotation. The right-handed polarized wave is an electromagnetic wave that conforms to the right-hand rule, and the left-handed circularly polarized wave is an electromagnetic wave that conforms to the left-hand rule. The polarization of the fixed antenna is circular polarization, so within the reading range of the antenna, the tag can be read even if it rotates at will, but for most tags that work in polarization, the receiving circular polarization When wave time, the power that the tag can receive also loses half, so when the reader adopts a circularly polarized antenna, the reading distance is shorter than that of a general linearly polarized antenna.

Physical parameters:

4. Passive electronic tags

The chip storage space is 2048 Bits, 64 bits UID and 216 bytes of user-defined space.
