1. Increase investment in science and technology and strengthen basic and applied research. New technologies are already widely adopted in the field of metrological weighing and control-such as mathematical modeling for control, systems theory, fuzzy logic, artificial intelligence, neural networks, digital filtering, vibration theory, damping technology, and self-diagnosis/adaptive technologies.
2. Develop proprietary weighing display controllers and pursue a strategy of combining internal development with external partnerships.
① Adopt a modular and intelligent approach to developing weighing display controllers, utilizing highly reliable PLCs and integrated chips (modules) for the hardware.
② Have equipment manufacturers define key control concepts, strategies, and technical standards (software), while collaborating with specialized weighing instrument manufacturers via OEM (integrated manufacturing) to achieve breakthroughs in production technology and manufacturing processes. Insights can be drawn from international peers; some companies do not manufacture the control instruments themselves but instead provide the solutions, design concepts, and software, outsourcing the actual hardware manufacturing to specialized producers to leverage the respective strengths of each party.
3. Standardize products. It is recommended to formulate national or industry standards for weighing display controllers based on the Chinese national standard GB7721-1995 and the internationally recognized OIML Recommendation R76. Compared to their international counterparts, domestic controllers suffer from limited functionality and a lack of bus communication capabilities. As DCS (Distributed Control Systems) become widespread in new cement plants, direct bus-based connectivity with DCS-enabling data and information exchange and simplifying system architecture-has become an inevitable trend. A new generation of international weighing displays already offers this functionality (supporting bus protocols and Ethernet), whereas such instruments are not yet available in China (where RS-232, RS-422, and RS-485 interfaces remain the norm). Addressing this gap is a key priority for future development.
