Abstract
The utility model discloses equipment for achieving power supply management based on a singlechip. The equipment for achieving power supply management based on the singlechip comprises a main system and the singlechip, wherein the singlechip is provided with a voltage detection end, a system heartbeat detection end and a control signal output end; the voltage detection end and the system heartbeat detection end are connected to a power supplying detection node of the main system; the control signal output end is connected to a power supplying control node of the main system; the control signal output end performs power supply control and main system restart according to the power supplying voltage and the system heartbeat state which are detected by the voltage detection end and the system heartbeat detection end. According to the utility model, the simple, efficient and reliable power supply management can be realized.
Description
Technical field
The utility model relates to the vehicle power management equipment, particularly relates to a kind of equipment based on the chip microcontroller power management.
Background technology
For power supply management device; Because the diversity of load equipment; At present single power supply management device has been difficult to satisfy present demand, how through simply, scheme realizes high efficient and reliable and according to the power management that different loads is controlled, is the problem that faces cheaply always.
The utility model content
The fundamental purpose of the utility model is exactly the deficiency to prior art, and a kind of equipment based on the chip microcontroller power management is provided.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of equipment based on the chip microcontroller power management; It is characterized in that; Comprise main system and single-chip microcomputer; Said single-chip microcomputer has voltage detecting end, system heart-throb test side and control signal output ends; Said voltage detecting end and said system heart-throb test side are connected to the power supply detection node of said main system, and said control signal output ends connects the power supply Control Node of said main system, and said control signal output ends is according to said voltage detecting end and the detected supply voltage in said system heart-throb test side and the system heart-throb state carries out power supply control and main system is restarted.
Be provided with at least one line between said main system and the said single-chip microcomputer and be used for heartbeat detection.
Said equipment is mobile unit.
According to the utility model; The power switch of main system and reset function are controlled by the single-chip microcomputer of independent setting, and single-chip microcomputer is provided with low electro-detection end, system heart-throb test side and control signal output ends, and main system is hanged down electro-detection and system heart-throb detection; When system's supply voltage is crossed when low; Turn off system power supply, after main system does not have heartbeat, then restart system, realized simple, efficient, reliable power management thus.
Description of drawings
Fig. 1 is the structural representation according to an embodiment of the utility model.
Embodiment
Below combine accompanying drawing that the utility model is further specified through embodiment.
See also Fig. 1; In an embodiment; Equipment based on the chip microcontroller power management; Comprise main system and single-chip microcomputer, said single-chip microcomputer has voltage detecting end, system heart-throb test side and control signal output ends, and said voltage detecting end and said system heart-throb test side are connected to the power supply detection node of said main system; Said control signal output ends connects the power supply Control Node of said main system, and said control signal output ends is according to said voltage detecting end and the detected supply voltage in said system heart-throb test side and the system heart-throb state carries out power supply control and main system is restarted.Preferably, be provided with at least one line between said main system and the said single-chip microcomputer and be used for heartbeat detection.
In a certain embodiments, said equipment is mobile unit.
According to the utility model; Single-chip microcomputer by independent setting hangs down electro-detection and system heart-throb detection to main system; When system's supply voltage is crossed when low; Single-chip Controlling is turned off system power supply, and then system is not restarted in control after main system has heartbeat, has realized simple, efficient, reliable power management by this.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
