Embodiment
The present invention provides a kind of dormancy of electron key low-power consumption power supply plan and awakening method, the electron key are suitable for
Passive electronic lockset.
Passive electronic lockset realizes that the method for " passive " is installation in lock similar to the control panel of access control system, power supply
It is partially integrated in electron key, while electron key has been internally integrated the key that can open lockset.When electron key goes to open
During lockset, while electron key is powered to lockset, lockset communicates with key, and key is downloaded to lockset by electron key
Interior, lockset judges whether key is correct, and key can be recorded if correct, opens door lock.Therefore, electron key is being not in contact with
The resting state that it is low-power consumption during its power supply that lockset, which is,.When electron key touches lockset, for lockset power supply, communication when, it is necessary to
Wake up to normal operating conditions.Electron key and lockset sign off, after leaving lockset or time-out, reenter resting state.
Therefore, the dormancy of electron key is the starting that electron key communicates with lockset and end time-out with the trigger condition waken up.
The mode that communication between electron key and corresponding passive lockset uses is serial communication.So pass through detection
The serial ports of electron key i.e. can determine whether electron key contacts with passive lockset, if need to wake up, if complete unlock into
Enter resting state.
The communication protocol process of serial ports is that serial ports is logical one, i.e. high level in the idle condition not communicated.Work as production
During raw communication, a start bit signal is produced first.Start bit signal is the signal of a logical zero, i.e. low level, represents logical
Believe the beginning of transmission.After being transmitted across initial signal, the transmission of data is carried out according to the baud rate of agreement.After being transmitted, it is set to
High level, is idle condition.
According to above-mentioned serial communication protocol, after it is idle condition to detect serial ports, start timing, the time exceedes setting
Threshold value after, electron key is set to resting state.When detecting serial communication, electron key is waken up from resting state
To normal operating conditions, with lockset into row data communication.
When using serial ports wake-up mechanism, the serial ports of electron key is also required in running order, and the power consumption of serial ports
It is higher.So this battery saving mode is also not up to minimum power consumption.Therefore, in order to further reduce the power consumption of electron key,
Under sleep mode, the serial ports of electron key is also inserted into resting state.At this time, serial ports can no longer wake up electron key, electricity
Work is will be unable to after sub- key dormancy.
Electron key also supports external interrupt wakeup after dormancy.According to the communication protocol of serial ports, serial communication is in the free time
State is high level, and start bit is low level, and a trailing edge is generated on this process nature, meets external interrupt wakeup

Dormancy：Assuming that Current electronic key is in normal operating conditions.Electron key monitors serial communication.If current key
Communicating with lockset, then electron key continues current work, communicates with lockset, completes unlocking, information communication, duplicated record
Etc. function.When electron key communicates completion with lockset, or key is left lockset by user, monitors that serial ports is high level, electronics
After key communicates with lockset no data, start timing module inside electron key, will after timing module reaches the threshold value of setting
The serial port pin of key is configured to common I/O mouths, and the external interrupt function of configuring trailing edge by the I/O mouthfuls.At this time, electronics
Key completes this task, it is entered sleep mode.Under sleep mode, electron key closes all peripheral hardwares, low into power saving
Power consumption mode.Complete sleep procedure.
Wake up：Assuming that Current electronic key is in the sleep mode of low-power consumption power saving.When user uses electron key and lock
Tool is contacted by probe, and electron key is powered to lockset, and serial ports between the two is connected by probe.Lockset and electron key into
Row serial ports is shaken hands, and start bit is sent to electron key.The serial port pin of electron key is currently configured as I/O mouthfuls common, and possesses
The external interrupt function that trailing edge interrupts.Serial port pin is high level in the dormant state, and start bit is low level, that is, is generated
One trailing edge.At this time, electron key carries out electron key by external interrupt to wake up to normal mode of operation.After wake-up,
The serial port pin configuration of electron key is matched somebody with somebody from common I/O mouths and puts back into serial ports pattern.After the completion of configuration, electron key recovers string
Mouth function, continues serial communication with lockset.Complete wakeup process.
Although present disclosure is discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned
