2026-08-27
The core difference between PLC controller sterilizer and MCU sterilizer lies in the system architecture and application scenarios. PLC is a complete control system for industrial site, which is suitable for large and complex equipment. Single-chip microcomputer is a microcomputer chip, which is suitable for small and simple equipment.
1. Comparison of core dimensions
1.1 Hardware and expansibility: PLC adopts modular design, with photoelectric isolation, strong anti-interference and easy expansion. Single-chip microcomputer is a bare chip, and its I/O driving ability is weak, so it needs to design its own peripheral circuit, and its expansibility is poor.
1.2 Programming and maintenance: PLC uses graphic languages such as ladder diagram, supports online program modification, and is easy to maintain. Single-chip microcomputer mostly uses C language or assembly, which requires a deep understanding of the underlying hardware, so it is difficult to upgrade and maintain the system.
1.3 Cost and applicable scenario: PLC is the first choice for mainstream large-scale sterilization equipment because of its high cost, but it can reduce the risk of downtime. Single chip microcomputer has low cost and is suitable for cost-sensitive small or household sterilizers.
2. Summarize in detail
2.1 PLC sterilizer: It has good stability and strong environmental adaptability, and is suitable for modern large-scale sterilization equipment with complex functions. It is the mainstream control scheme at home and abroad.
2.2 Single-chip sterilizer: small size, low power consumption, can complete basic control functions, but limited by resources, not suitable for complex tasks, mostly used in early or small equipment.

Lithotripsy is recognized as the "gold standard". Whether it is hard oxalate calcium stones, tough cystine stones, or oddly shaped antler-shaped stones, holmium laser can efficiently crush them; combined with the Moses pulse modulation technology, the displacement of stones is smaller and the efficiency is higher. It can even "use one light for multiple purposes" - during lithotripsy, it cuts open the inflammatory polyps surrounding the stones, treats ureteral stenosis, and solves multiple problems in one surgery.
