The single board monitoring management system comprises the programmable logic device, a power management module, a hardware system initialization module, a device state management module and an upper computer communication module. The power supply management module comprises an analog-to-digital converter module, a user Flash memory module and a power supply power-on enabling module; the hardware system initialization module comprises a low-speed interface module, a device reset control module and a watchdog module; the device state management module comprises a device error reporting and interruption detection module and a local register for storing a system state; the upper computer communication module comprises an SPI Slaver module, a UART Slaver module and a communication IO module between the system main controllers. Various tasks with high real-time requirements can be completed, various communication interfaces and functional modules are simulated according to specific system requirements, the CPU is assisted in completing various functions, the processing capacity of the CPU is released, and the universality and robustness of the system are enhanced.

Description

technical field [0001] The invention discloses a single-board monitoring and management system based on programmable logic devices, and relates to the technical field of electronic product system design. Background technique [0002] Industrial-grade systems have very high requirements for product stability, and require real-time monitoring and control of various product states, such as single-board power consumption, temperature, and chip operating status. Generally, the system will use a single-chip microcomputer or other similar simple CPU for monitoring, because the single-chip microcomputer design is not difficult, has comprehensive functions, and low cost, and is widely used. But for some tasks with very high real-time requirements, the single-chip microcomputer cannot meet the system requirements. [0003] For example, the system requires real-time monitoring of multiple power supplies, multiple temperature points, and multiple device states on a single board. The im...
