Cotton is an important economic crop in my country. Cotton farmers, cotton, processing, and transportation constitute a complete industrial logistics chain. Among them, the processing link is the most important, and it is responsible for items such as acquisition, quality judgment, processing, weighing, and packaging. Manual recording has been used in this link, which is inefficient and error-prone. Our company proposes an electronic label solution for this demand, which can solve the problem of identification and data collection in the product flow process. A system structure Option 1: (large warehouse)
Scenario 2 : Electronic scale Two electronic tags and reading equipment Electronic tags are the most advanced radio frequency induction technology (RFID). Since 1998, Texas Instruments (TI) and Philips of the Netherlands announced the development of a cheap non-contact sensor chip. By 2000, The International Organization for Standardization has written this non-contact sensor chip into the international standard ISO15693. Due to its unique characteristics and advantages, it is now widely used in various industries and fields. 1 Features of electronic tags: ●Passive long-distance reading and writing: up to 1.2 meters;
●Anti-collision technology: Compared with barcodes, it does not need to be aligned and scanned in a straight line, and the reading and writing speed is fast. It can recognize multiple targets and recognize in motion, and can recognize up to 50 at the same time per second. ●Internationally-used frequency: 13.56Mhz ±7KHz ●Flexible internal storage space: manufacturers can define the storage capacity of each model product and the number of bytes in each sector according to their own needs, and the read-write device can read the memory configuration information, which is convenient for operating different types in a comprehensive application. Label products. ●Internationally unified and non-repetitive 8-byte (64bit) unique identifier (UID), of which the first 1-48 bits total 6 bytes, which is the manufacturer’s product code, and the 49th-56th bit is 1 word The section is the manufacturer’s code (ISO/IEC7816-6/AM1), and the highest byte is fixed as “EO”. ●It can be read and written repeatedly and the sector can be locked once independently, and can lock important information according to user needs; existing products generally use 4-byte sectors, and the memory ranges from 512bit to 2048bit. ●Long service life (≥10 years or 100,000 times of reading and writing), no mechanical wear, no mechanical failure, and can be used in harsh environments. (Working temperature: -25 degrees ~ +70 degrees) ●Flexible packaging, diversified packaging: its ultra-thin and a variety of different sizes, so that it can be packaged in paper, plastic products (PVC, PET), can be used in different occasions, can also be laminated to make cards. Electronic tags are suitable for application in the current scientific inventory management system because of their anti-collision, arbitrarily packaging, long service life, and reusable characteristics. The current inventory management system usually uses barcode labels or manual inventory management receipt writing to support its own inventory management. However, barcodes are easy to copy, not stain-proof, and not moisture-proof, as well as the inevitable shortcomings of manual document writing and easy to cause human losses, which make the current domestic inventory management supply chain always have defects. With the application of electronic tags, the latest technology products, the above-mentioned problems can be fundamentally solved. 2 How to install the electronic label on the cotton bale Due to the small chip size and the flexible structure of the inductive antenna, the electronic tag is
Various methods can also be used for installation on the cash drawer. 1) Make a self-adhesive sticker and stick it on the designated position of the cotton bale.The advantage is cost
Low and easy to install. The disadvantage is that it is not easy to recycle and reuse, and it is easy to damage. 2) Encapsulated into an ABS nameplate and hung on the designated position of the bread.Easy to have many advantages 3 High-power tag reading and writing equipment (MC5000) The MC5000-ARM9 super intelligent information processing terminal is the most powerful industrial-grade data processing control terminal today. He integrates speed, design, communication, storage, wireless, and multimedia functions. It can realize wired and wireless remote data transmission, identity recognition, automatic tracking, industrial control, data processing and other functions at the same time. With the ARM9 super intelligent information processing terminal, it can solve the synchronization of physical logistics and information flow in logistics; solve unmanned power stations and telecommunication equipment rooms from time to time monitoring, anti-theft, and remote control; solve data collection of large-scale meters in power plants and water plants ; Solve the remote data collection and control of the oil field; solve the data collection and product tracking in the manufacturing process; solve the unified platform management of large-scale building network, security, monitoring, access control, etc. Host performance indicators:
