How to ensure the safe operation of embedded control hardware and software for smart home appliances?
Recently, the HK32C030/C005/C105/C207/R78X series products of the Hang Shun chip have passed the IEC 60730 certification, providing a functional safety library that meets the Class B standard, reducing the time and cost of terminal product safety certification for smart home appliance manufacturers, helping to shorten product launch time, and improving product stability and security from the bottom layer.
IEC 60730 certification certificate
Security is the life of smart home appliances! International Electrotechnical Commission: IEC 60730 "Gold Standard"
The International Electrotechnical Commission has developed the IEC 60730 standard to define various safety testing and diagnostic methods that can detect system faults in a timely manner and eliminate the risk of harm. When this standard is applied to the design of white goods and other appliances, it can improve the safety of smart home appliances.
IEC 60730 divides the safety standards for microcontrollers based household appliances into three categories:
•Class A: Control functions unrelated to device safety
Application scenarios: temperature and humidity control, lighting control, etc
•Class B: Intended to prevent unsafe operation of controlled equipment
Application scenarios: washing machines, refrigerators, etc
•Class C: Intended to prevent special hazards, such as preventing equipment explosions
Application scenarios: automatic burners, gas dryers, etc
Typical household appliances, such as white batteries, need to comply with Class B protection, which includes monitoring or detecting key components such as CPU registers and program counters, interrupt processing and execution, system clock frequency, and memory detection. This can effectively prevent harm to household appliances caused by unsafe operations, such as the electric door lock of the washing machine and the motor thermal shutdown mechanism.
Hangshun HK32MCU provides a complete functional safety library to assist customers in achieving functional safety design
Home appliance manufacturers can embed the certified HK32MCU security program library into the entire system software to achieve self detection function, and then apply for IEC 60730 functional safety standard certification for the final product.
Under normal circumstances, the program will start with a reset and go through the green box to complete all functions, including the startup configuration of the application app, the execution of the Main function, and the execution judgment of multiple interrupts. In order to achieve the safety function of IEC 60730, we have added a blue section in the program, which includes module safety startup detection after reset and runtime cycle detection. At the same time, we have added a failure judgment interface, as shown in the overall flowchart of the functional safety software.
The startup detection includes:
CPU startup detection
Detection of watchdog startup
Flash startup detection
RAM startup detection
Clock start detection
Detect when control flow starts
The runtime cycle detection includes:
CPU runtime detection
Stack boundary runtime overflow detection
System clock runtime detection
Flash CRC runtime detection
Control flow runtime detection
Watchdog refresh during runtime
