Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Specifically, referring to Fig. 1 to Fig. 2, following embodiments of the invention are opened in the original machinery of power control circuit of equipment
Close on the basis of K1 (power on/off key), increase a state operating key K2.When pressing, such as long-press state operating key K2 is (right
First mode is answered to operate) after, the sign of flag of the mode of shutdown is set to designated value such as 0 by microcontroller, and Flag value is deposited
The nonvolatile memory such as Flash (flash memory) for entering to be internal or external at the microcontroller performs power-off operation, equipment afterwards
System switches into off-mode, if now pressing mechanical switch K1 makes device powers down (OFF), then presses mechanical switch K1 and makes to set
Standby electric (ON), equipment can't carry out system reboot, only when pressing such as short-press state operating key K2 (correspondences second again
Pattern is operated), device systems, which can just restart, enters normal operating conditions.When equipment meets with exception in normal operation
After power-off, equipment enters off position, when external power source recovers, and power control circuit can meet with dash current and produce one
Pulse is as device systems starting-up signal, so hereafter equipment reboots into normal operating conditions.In addition, when device upgrade firmware
During program, after the completion of upgrading, device systems can also reboot into normal operating conditions automatically.
It is external or internal to preserve each category of normal operating in the nonvolatile memory (Fig. 2 is not drawn) of microcontroller
Will, and made a decision after device power.For example, the last shutdown that sign of flag is 0 expression equipment is because state operating key
K2 is long pressed, and sign of flag for the last shutdown of 1 expression equipment is shut down because meeting with abnormal power-down, and sign of flag is 2
Represent that equipment carries out firmware upgrade.As shown in figure 1, when to device power, the power supply control program in microcontroller is first
Into Boot areas (bootstrap area), the value of the sign of flag of last shutdown mode is read from nonvolatile memory, is sentenced
Disconnected Flag value.When Flag is 0, characterize last shutdown be because state operating key K2 is pressed (such as long-press), therefore
Boot areas wait state operating key K2 is pressed (such as short-press), when pressing (such as short-press) state operating key K2, power supply control
Processing procedure sequence jumps to APP areas (application area) execution, device systems is rebooted into normal operating conditions；When Flag is 1, table
It is that after re-powering, the power supply control program in microcontroller is redirected because equipment meets with abnormal power-down to levy last shutdown
Performed to APP areas, equipment is carried out system reboot, afterwards normal operation；When Flag is 2, characterizes device systems and consolidated
Part is during upgrading, after upgrading is completed, and the power supply control program in microcontroller jumps to the execution of APP areas, restarts equipment, afterwards
Normal operation.Herein what deserves to be explained is, the mechanical switch K1 of transformer input side is connected in power control circuit shown in Fig. 2
Can be ship type switch, the state operating key K2 for being connected to transformer outlet side can be button such as thin film switch, connection
Can be MCU (single-chip microcomputer) or programmable logic device in transformer outlet side and with the state operating key K2 microcontrollers electrically connected
Part such as FPGA.
Hold above-mentioned, the power control scheme of this implementation can also make device systems switchably in off-mode, sleep
Three kinds of working conditions such as state and normal operating conditions, as shown in figure 3, user can be in off-mode, sleep state and normal
Switching random back and forth between these three working conditions of working condition.When device systems are in normal operating conditions, Yong Huke
To be switched to off-mode and sleep state, such as long-press state operating key K2 enters off-mode, short-press state operating key K2
Into sleep state；When device systems are in off-mode, user can be switched to normal operating conditions, such as short-press state
Operating key K2 enters normal operating conditions；When equipment be in sleep state when, user can be switched to normal operating conditions (or
Holding state), such as short-press state operating key K2 enters normal operating conditions.No matter which kind of working condition device systems are in,
After device powers down upper electricity again, system can all enter normal operating conditions.
Furthermore, it is worth mentioning at this point that, when system is in sleep state, it is to turn off part power consuming device, to reach section
The effect of energy.In addition, toggle speed of the present embodiment from sleep state to normal operating conditions is fast, short-press state operating key is only needed
K2 is to switch to normal operating conditions.
Referring to Fig. 4, it is that the embodiment of the present invention is shown using the part-structure of the electronic equipment of power control circuit shown in Fig. 2
It is intended to.In Fig. 4, the housing of electronic equipment 40 includes front panel 41 and the backboard 43 relative with front panel 41, mechanical switch K1
It is mounted on backboard 43, state operating key K2 is mounted on front panel 41.Certainly, mechanical switch K1 it is also contemplated that
It is arranged on the side plate of the housing of electronic equipment 40 on even front panel 41, is only provided on backboard 43 more typical.This
Outside, it is to be understood that front panel 41 typically can also set display screen for example in addition to installation settings state operating key K2
The device needed for control panel such as liquid crystal display and knob (or button).As for the present embodiment electronic equipment 40 its can be various electricity
Sub- equipment is as display control apparatus such as display controller, sending card, video processors.
In summary, the embodiment of the present invention can reach following one or more beneficial effects：(a) state operating key is set up
Carry out power on operation and the working condition switching of control device, convenient operation reduces cost of hardware design；(b) micro-control in equipment
Power control scheme is configured with device processed, the reliability, the free degree and autgmentability of equipment is improved；(c) unit exception power-off is extensive
