Factory control:
We assume in advance that the software system with the function of the management platform has been established. When the electronic scale leaves the factory, not only does it have a unique number on the nameplate, but the same unique code also exists in the self-contained repeatable read-write chip. Before leaving the factory, there will be In one step, all the production information of the scale is read into the software system, so that no scale has a unique record in the system. After the record is established from the source, it is easy to control its flow in the future.
Sales Process Control:
First, sellers at all levels must be authorized, so that the system will give each seller a unique code to trace the seller’s behavior.The scales enter the sales stage. Since they are mainly aimed at the bazaar, whether it is a lower-level wholesaler or a market, there may be many ways to purchase in bulk. When selling the batch of scales, the authorized seller will use the handheldRFIDThe reader reads and writes the data of each scale, and then transmits the data to the central database of the software system through the network, and then records the flow direction of the scale. Under the condition that sellers at all levels are required to do a good job in data collection, writing and recording, and supervise them, in the sales link, the circulation process and final flow of each scale are clearly recorded in the software management system for easy traceability.
Verification and Maintenance Controls:
This link is the most prone to problems, and is also the key to the entire anti-cheating system. The control core of this link lies in the use of the special hardware of the calibrator.
The main functions of the calibrator are:
One isInternet of Things(including the upgrade of the scale chip, the transmission of the identification code and the identification of the verification/maintenance personnel);
The second is to carry out weighing calibration symmetrically;
The third is to have the identification function, which can identify the verification/repair personnel, improper maintenance and counterfeit products according to the unique code provided.
The calibrator is only granted to metrology verification institutions and accredited measuring instrument repair institutions, which is an important part of realizing the legal management of measuring instruments. In the software management system, both verification institutions and maintenance institutions are given unique code identifications. Although both the verification agency and the repair agency are granted the hardware of the calibrator during use, their functions are different. As the management department, the calibration agency and the login account possessed by the verification agency have all the functions of the calibrator. Since the repair organization mainly maintains other programs and functions except for measurement adjustment, its calibrator is not granted the function of measurement calibration and adjustment on the hardware. It is the repair party and the electronic scale docking to perform authentication records and then start maintenance. If there is a program change device other than measurement and calibration, we will describe the work flow of both parties separately. The calibration agency will carry a calibrator when calibrating the electronic scale. After being identified, it will be calibrated. At the same time, the calibrator will record which account was used to calibrate the scale with what code and when. After the calibration and calibration are completed, the calibration agency will use the calibrator to transmit the stored information into the management system. After the system is installed, the system will record the verification status of the electronic scale, the calibration status of the table, the equipment and other information, and allow users and consumers to inquire through the software platform to understand the management status of the measuring instruments. When repairs are required for unacceptable faults, the authorized repair organization must first use the calibrator to connect with the scale to confirm the identity, and then re-set the program after conforming to the requirements, and then use the calibrator again to calibrate before use. The scale, an important link that can lead to cheating, is well controlled.
