The acceptance committee composed of 7 experts from the China Academy of Metrology, China Weighing Instrument Association, and China Test Technology Research Institute, etc., listened to the project work report and watched the live demonstration. After consultation and discussion, they agreed that the Jiangsu Provincial Institute of Metrology The submitted acceptance data is complete and the objectives of the project task book have been fulfilled, which meets the acceptance requirements for science and technology projects. The acceptance committee agreed to pass the acceptance and highly evaluate the two science and technology plan projects.
The â€œAutomatic Weigher Type Evaluation and Detection System Developmentâ€ project has for the first time proposed and adopted advanced technologies such as dynamic automatic quantitative control, belt running status parameter measurement and control, automatic measurement and control of experimental data, and remote transmission and monitoring of experimental conditions, and developed the most complete experimental bandwidth (400mmï½ž The continuous cumulative automatic weighing (belt scale) detection system with 2400mm), the highest accuracy level (0.2 class) and the largest experimental flow rate (7200t/h) fills the international gap and prompts OIML R50 "continuously accumulating automatic weighing instrument (belt scale) The highest level of accuracy in the international recommendations has been raised from 0.5 to 0.2. The research and development of the belt tension and horizontal force, belt slot angle, roller bounce and turbulence and other influencing factors of the measurement and control technology, to achieve the simulation of the belt weigher on-site conditions, established the only international continuous automatic weighing instrument (belt Scales) Perform a full-performance experimental system including durability testing, and the overall technical level leads the world.
The â€œHandheld Electronic Valuation Scale Anti-Cheat Supervision and Detection Systemâ€ project is based on Android software development technology. It embeds an independently developed program segment check code special algorithm function module in the main control unit of the electronic pricing scale and uses a 128-bit random password to encrypt and receive the electronic data. Valuation scale verification code, using data encryption, Bluetooth communication, Internet data exchange, server database management and other advanced technologies, effective monitoring of electronic pricing scale software, is a domestic initiative, the electronic balance of the use of trade settlement test set detection and The integration of supervision and management provides reliable technical support for the convenient detection of cheating software.

There are two types of Ordinary Pins
including the bare-string pin and plastic-wrapped pin. The bare-string pin is
made of high-quality and abrasion-resistant steel wire, suitable to apply in
the corrosive condition or sites with gravel materials. The plastic-wrapped pin
is wrapped with plastic outside the steel wire, which makes it smooth and
enhances the abrasion-resistance.
