Embodiment Construction
[0037] Integrated microsystem usually has clock circuit part (including AD clock circuit, processor clock circuit), 3101 processor, status display (GPIO circuit) and communication circuit (UART chip), storage circuit (including SRAM chip, SDRAM chip, FLASH chip ); 3101 processor includes SRAM controller, SDRAM controller, FLASH controller, FLASH controller, AD acquisition circuit.
[0038] The present invention adds a voltage acquisition circuit part, a current acquisition part, and a real-time clock circuit on the basis of the existing framework of the integrated microsystem, and embeds a health processing submodule in the 3101 processor to process health state information. The voltage acquisition part collects the operating voltage state of the integrated system. The 3.3V and 1.8V voltages of the system are collected, and the corresponding output terminals are connected to the AD_IN_3 and AD_IN_4 terminals of the SPARC V8 processor; the current collection part collects the o...
