Abstract
An embedded method for monitoring the state of a power supply blade in real time can process tasks with higher priority and more urgent tasks to realize real-time performance because freertos supports preemptive tasks. When the problems of abnormal work of the power supply module, reset requirements of external transmission and the like occur, the MCU takes corresponding actions in real time according to the sending signals, and the abnormal work of other blades of the whole case caused by the power supply problem of the power supply blade is avoided. Meanwhile, the voltage measured by the sensor I, the working temperature of the power supply module of the sensor II and the ambient temperature measured by the sensor III are sent to the MCU, and the MCU arranges the information and then transmits the information to the upper computer through a hardware I2C interface. Resource management and state monitoring are realized, and the layout space on the board can be effectively reduced.
