Hardware measures:

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

① Shielding: the main components such as power transformer, CPU and programmer shall be shielded with materials with good conductivity and magnetic conductivity to prevent external interference.

② Filtering – various forms of filtering are used for the power supply system and input lines, such as LC or π type filtering network, to eliminate or suppress high-frequency interference and weaken the interaction between various modules.

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

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

⑤ Adopt modular structure – this structure is helpful for 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 is also helpful to quickly find the cause of the fault.
