Hardware measures:

The main modules adopt large-scale or ultra-large-scale integrated circuits. A large number of switch actions are completed by contactless electronic memory. The I/O system is designed with perfect channel protection and signal conditioning circuits.

① Shielding – The power transformer, CPU, programmer and other main components are shielded with materials with good conductivity and magnetism to prevent external interference.

② Filtering – adopt various forms of filtering for power supply system and input line, such as LC or π type filtering network, to eliminate or suppress high-frequency interference, and also weaken the mutual influence between various modules.

③ Power supply adjustment and protection – The+5V power supply required by the core component of the microprocessor is adjusted by multi-level filtering and integrated voltage regulator to adapt to the fluctuation of the AC power grid and the impact of overvoltage and undervoltage.

④ Isolation – between the microprocessor and the I/O circuit, photoelectric isolation measures are adopted to effectively isolate the electrical connection between the I/O interface and the CPU, and reduce faults and malfunctions; The I/O ports are also isolated from each other.

⑤ Adopt modular structure – this structure is conducive to short-term repair in case of failure. Once a module is found to be faulty, it can be replaced quickly to restore the system to normal operation; At the same time, it also helps to find the cause of the fault faster.
