Description
Technical Field
The present invention relates to the field of electronic product technologies, and in particular, to a standby system and a standby method capable of self-waking.
Background
In some special fields of industrial control and test measurement, extremely strict requirements are imposed on the power consumption of equipment. For example, some field instruments need to be placed in the field or buried underground for work, so that users cannot approach or even reach the field instruments, and use batteries for power supply, so that the volume of the field instruments is limited, and the field instruments can be continuously used for at least one year.
At present, the mainstream low-power standby solution is to make a microprocessor in a deep sleep state, generally, a low-power Real-Time Clock (RTC) circuit provided in a single chip microcomputer is used for timing during work, a corresponding function is completed by timing wake-up, and then the single chip microcomputer enters sleep work. However, in this way, although the microprocessor is already in the low power consumption standby mode, the power circuit of the system is still in the on state, the power chip itself has static power consumption during operation, and other peripheral components still inevitably generate current consumption, and therefore, the system cannot be applied to the above-mentioned situations with strict requirements on power consumption.
In the patent with application number 201310349034.7, a low-power consumption standby circuit and a control method for a single chip microcomputer are provided, which enable the power supply of the single chip microcomputer to be completely cut off when a system is in standby, thereby realizing low power consumption, and simultaneously, a corresponding trigger switch is designed, so that the single chip microcomputer can be easily switched to a normal working mode, the use is convenient, and the circuit does not need to be redesigned for the electric appliances which use the single chip microcomputer without the low-power consumption mode or similar functions, and the realization is easy. However, when the circuit is in a standby state, the circuit cannot be automatically awakened, and the system can be awakened only by manually pressing the standby key by the outside, which does not meet the requirements of the occasions.
In the' 201210214428.7 patent, before the system enters the standby state, the currently running system state information is saved in a suitable medium, and the index of the current system state information is saved in the RTC power domain while the system state information is saved; and when a standby command of the system is received, the system power supply is closed, and when the system is restarted, the system state information before standby is quickly found from the stored index information and is recovered.
