Problems solved by technology

If it is used near the equipment with high electromagnetic interference in the power system, the internal timer of the MCU is easily damaged by interference, the software watchdog will fail, and the reliability will be reduced.
[0003] The reliability of the software watchdog is poor. For example, if the internal timer of the system fails, it cannot be detected.
Of course, there are also mutual monitoring through dual timers, which not only increases system overhead, but also cannot solve all problems, such as interrupting system failures that cause timer interrupts to fail

Abstract

The invention relates to the technical field of Internet of Things, in particular to a reliable universal chip integration application system for power Internet of Things. The system comprises a maincontrol module, a radio frequency circuit module and a system self-recovery anti-interference circuit, wherein the main control module is connected to the radio frequency module through a communication interface, and the main control module is connected to the system self-recovery anti-interference circuit. According to the system, the modularization of a power Internet of Things chip is realizedand an own Internet of Things communication protocol is brought, and meanwhile, an independent hardware watchdog circuit is adopted, a self-recovery function of a main control MCU is achieved when themain control MCU encounters an interference fault, the anti-interference capability is improved, and the operation reliability of an Internet of Things module is greatly improved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, and more specifically, to a reliable universal chip integrated application system for the Internet of Things. Background technique [0002] The current IoT module, in order to improve reliability, will adopt the internal software watchdog technical solution. The software watchdog uses a timer inside the MCU, and its timing output points to the reset terminal of the MCU. The program clears the timer within a certain time range (commonly known as "feeding the dog"), so when the program works normally, the timer always Can not overflow, it can not generate a reset signal. If the program breaks down and does not reset the watchdog within the timing period, the watchdog timer overflows to generate a reset signal and restarts the system. The software watchdog can simplify the hardware circuit design, but it is not as reliable as the hardware timer. If it is used near the equipment wit...
