I. Inherent Defects of Traditional Measurement and Control Methods
1.Contact Pressure Gauges: Bulky in size, difficult to maintain, lacking in functionality, and extremely inconvenient for setting pressure process parameters in practical production.
2.PLCs with A/D Modules: High system hardware and retrofit costs, with non-intuitive configuration and modification of process parameters.
3.Analog Comparator Circuits: Simple circuit structure, lacking necessary intelligence and multi-stage control capabilities.
II. Reasons Prompting the Development of this Intelligent Microcontroller System
1.Harsh Operating Conditions and Strict Safety Requirements: Diamond synthesis takes place under extreme conditions of high temperature and high pressure ($2000^\circ\text{C}$ / $100\text{ MPa}$), running continuously year-round in an environment with severe industrial interference. System failure resulting in a false pressure-relief command can trigger an explosion, while overtravel protection failure can cause catastrophic equipment damage; hence, a highly reliable, anti-malfunction system is essential.
2.Advantages of Combined Software-Hardware Anti-Interference Design: Using a microcontroller as the core controller, the system combines hardware measures (photoelectric isolation, LC filtering, complex address decoding, watchdog) with software strategies (PLC-like intermittent scanning, digital filtering/smoothing, error-tolerant process parameter protection), thoroughly solving common issues like system crashes and poor noise immunity in traditional setups.
3.Cost-Effectiveness and Ease of Adoption: Compared with traditional solutions, this intelligent instrument is fully featured, easy to operate, low-cost, and well-suited to domestic industrial needs, effectively upgrading the informatization and intelligence level of synthetic diamond manufacturing equipment.
