business background
Tires are one of the most important components of automobiles. Bus tires have different brands, large numbers, frequent circulation, high data update frequency, and heavy tasks for tire managers. At present, the Guangzhou FAW bus has a huge and complex bus tire management system when using, repairing, retreading and managing tires. In terms of tire management, Guangzhou FAW Bus is actively exploring information technology. The current method is to manually brand tires to identify them, and then use paper records to record tire usage.
Traditional way:
Manual branding and manual copying can easily lead to confusion of information, and the subjective arbitrariness is great. One tire corresponds to multiple identification numbers, or multiple tires correspond to one identification number, which makes it impossible to track and query tire information. Manual branding can also cause the shortcomings of damaging the tires, or make the staff unable to identify the doubts of the branding;
There are many processes and a wide range of tire circulation, which often causes the storage, distribution and information tracking of tires to be in an unmonitored state.
Smart way:
The use of smart chips effectively solves the shortcomings of traditional tire management such as the troublesome manual branding operation, the poor time efficiency of paper records, and the large workload of warehouse inventory.
Project Background
ZHIYUAN Electronics and Guangzhou FAW bus system integration partners jointly promote the intelligent tire management system. As a hardware equipment provider, ZHIYUAN Electronics launched HPC-6000UHF series handheld UHF equipment and fixed UHF products based on the R2000 solution, supplemented by an intelligent tire management system, and successfully installed car tires that can be read at a distance of more than 50CM Tire label.
Smart tire management system
Attached to the smart tire label, the smart tire management system plays a very important role. It will be connected with intelligent systems such as bus smart departure and speed limit monitoring, which greatly increases driving safety. For example, if the tire pressure is far lower or far higher than the normal value of the specified tire pressure during driving, the system will automatically pop up a warning message, and the staff can deal with it in a timely and accurate manner according to the reminder to avoid tire blowout accidents. The occurrence of, so that passengers can take the bus more at ease;
The management of tires is more intelligent, quantitative and qualitative:
A. Method of implanting tire rubber: mainly done by the tire manufacturer
The purpose is: to compare the mileage and degree of wear and tear of different brands on buses;
It functions as the tire’s “electronic ID card” and saves important data such as the production serial number, production date, identification code and other important data in the entire life cycle of the tire from the factory, maintenance, refurbishment, and scrapping in the chip.
B. Tire inner wall inlay method
The purpose is: to effectively solve the shortcomings of traditional tire management such as the troublesome manual branding operation, the poor time efficiency of paper records, and the large workload of warehouse inventory.
Tyre operation process
For every tire operation, such as quality inspection, road team distribution, inventory check, tire disassembly and assembly, etc., the manager only needs to scan the tire code with the handheld computer, and then upload the tire operation information to the network management terminal to form an electronic operation record . At the same time, tires and buses can be bound. Each bus has a car sticker with a chip on the lower right corner of the front windshield. For the first tire installation, you only need to scan the body chip and the tire chip with a handheld to realize the binding. Provide reliable data for tire maintenance and refurbishment.
Solve the problem
Solve the problem of tire label reading, requiring a reading distance of 30-50CM;
1. Recommended hardware: HPC-6000UHF with 8000mAh capacity and handle. The 8000mAh super-capacity battery fully guarantees the long battery life of the device, reduces on-site charging, and escorts customers’ high-efficiency work efficiency.
2. Stable reading distance of embedded tire tags;
First of all, the key point is to select a suitable label, which can remain undeformed in the high temperature and complex environment of the tire running process and cause degradation of read and write performance.
Secondly, ZHIYUAN Electronics HPC-6000UHF series products have conducted in-depth research and secondary development on the UHF antenna used, optimized the overall performance, and ensured the central frequency point, bandwidth, standing wave ratio and other parameters of the antenna. The one-to-one matching between the devices fully guarantees the ultra-stability of the device’s reading and writing effects and the consistency of the products.
Through actual testing and one-quarter verification, the stable reading distance of 30-50CM required by the user for the tire label is finally guaranteed, and the effect remains unchanged after one quarter.
Comparison of the advantages of smart labels with traditional barcodes
1. Non-contact data collection
RFID technology has greatly enhanced the manager’s ability to collect, exchange and track information on the collected objects. The user does not need to touch the trash can at close range, which reduces the worker’s inhalation of the aftertaste of the trash and improves the work efficiency, thereby helping the manager to implement dynamic management of the trash can.
2. High security
The data access of the label is protected by a password, the identification code is unique and cannot be forged, and the label indicates encryption technology. This high-security protection measure makes the data on the label not easy to be forged and tampered with.
3. Small size and diversified shapes
Since the RFID identification tag can be made into a sticker type, it is ultra-thin and small in size. Specialize in manufacturing smart labels that conform to the surface of trash cans;
4. Reusable
Nowadays, the barcode cannot be changed after it is printed, and the RFID tag can repeatedly add, modify, and delete the data stored in the RFID tag to facilitate the update of information.
5. Anti-conflict
Trash cans are usually stacked together while waiting for transportation. Different types of trash cans can’t be placed before and after; using Impinj’s R2000 and R500 solutions, it has multi-card collision recognition technology, which can identify more than 200 at the same time. You can also search for a specific label within a few meters of cards, and the convenience of inventory and search is outstanding.
6. Can be combined with barcode
The surface of the electronic label can be printed with patterns and barcodes, and can be used in combination with barcodes. HPC-6000UHF can be equipped with a two-dimensional barcode scanning engine, which is convenient for one machine for multiple purposes, checking information and reading barcodes on the job sheet.
