Problems solved by technology

When the power control processor crashes, the usual reset method will cause the main control processor to fail and be powered off, causing the main control processor to restart or shut down, and because the main control processor needs to load more tasks, the restart time is relatively long. If the power management controller is not reset, the function cannot be automatically restored after the processor crashes, which will affect the power on and off control function, and the user may be required to forcibly cut off the power by disconnecting the power supply or removing the battery. , which also affects the user experience

Abstract

The invention relates to relates to a power supply controller and a patient monitor thereof, and belongs to the technical field of electronic circuits. The power supply controller comprises a power supply and first and second power supply circuits connected with the power supply; an enablement control circuit transmits a level signal to the first power supply circuit; the first power supply circuit outputs a power supply signal to a power supply control processor; the first output end of the power supply control processor is connected with the second input end of the enablement control circuit, and the second output end of the power supply control processor is connected with the input end of the second power supply circuit; the power supply control processor is also connected with a watchdog circuit; the output end of the second power supply circuit is connected with the input end of a master control processor, the third input end of the enablement control circuit and the input end ofthe second power supply circuit; and a second resistor is connected in series between the output end and the input end of the second power supply circuit. Thus, the power supply control processor canbe reset during dead halt without influencing the power supply state of the master control processor, and user experience is optimized.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a power control device and a patient monitor thereof. Background technique [0002] With the development of science and technology, microprocessors such as Microcontroller Unit (MCU) and Digital Signal Processor (Digital Signal Processing, DSP) have also been widely used in electronic equipment in various fields; During the application process, it may crash due to internal program reasons or external electrical interference, which will affect the normal function of the system. In order to end the crash state in time and reduce possible losses as much as possible, a watchdog is usually configured for the microprocessor. [0003] However, in the existing electronic equipment, the micro-control unit is divided into two categories according to different functions, which include: the main control processor and the power control processor; wherein, the power control proces...
