The input of A power supply 16 is derived from DC filter unit 3, it is sent to Power Management Unit 15 through A power supply 16 conversion output, there is provided required DC supply for microprocessor unit 9, keyboard unit 6, display unit 7, switch element 8, remote switch 18 and WIFI module 10, b power supply 17 is lithium battery, in order to strengthen the instrumentality of power supply, the present invention is configured with a set of+5v stand-by power supply being made up of the two chargeable leopard cat ion batteries of section, and the charge and discharge process of this stand-by power supply is completely by this intelligent power complete independently.Its output of b power supply 17 is also directed to Power Management Unit 15；In alternating current power supply normal power supply, the voltage of A power supply 16 is preferentially sent to microprocessor unit 9, keyboard unit 6, display unit 7, switch element 8, remote switch 18 and WIFI module 10 by Power Management Unit 15；When alternating current power supply is not normal, b power supply 17 is sent to microprocessor unit 9, keyboard unit 6, display unit 7, switch element 8, remote switch 18 and WIFI module 10 it is ensured that ensureing the normal operation of this Intelligent switch power supply by Power Management Unit 15.
Alternating current power supply is not normal to be occurred in following state：
When the input of DC/DC unit or output are transfinited, when AC-input voltage transfinites, under above state, microprocessor unit 9 all can send action command and turn off exchange input channel, have no progeny when alternating current path closes, electromagnetic interface filter unit 1, rectification unit 2, DC filter unit 3, PFC correction unit 4, DC/DC unit 5 all cannot work, and now b power supply 17 passes through Power Management Unit 15 provides working power to microprocessor unit 9, keyboard unit 6, display unit 7, switch element 8, remote switch 18 and WIFI module 10.Due to DC/DC unit input voltage measurement sensor 11；DC/DC unit output voltage current detection sensor 12；AC-input voltage detection sensor 14 is all passive sensor, in this case, they still work, as long as microprocessor unit 9, keyboard unit 6, display unit 7, switch element 8, remote switch 18 and WIFI module 10 have working power, the data of collection still uploads to microprocessor unit 9, to collecting, DC/DC unit inputs or output is normally and when AC-input voltage is normal, microprocessor unit 9 can send action command to switch element 8 again and open exchange input channel so that this Intelligent switch power supply normally runs.
The function of can achieve remote opening by WIFI module 10 such as mobile phone is to ensure that using the Another reason of b power supply 17, is simultaneously provided with remote switch 18.In normal operation, remote switch 18 be constantly in normally closed（Turn off）State, when when remotely needing shutdown, as off signal is sent using mobile phone, by network and wireless router, communicated with microprocessor unit 9 by WIFI module 10 again, after microprocessor unit 9 process signal, send action command remote switch 18 is opened and be in opening, make that the exchange input channel of electromagnetic interface filter unit 1 disconnects and non-output signal is sent, cause rectification unit 2, DC filter unit 3, PFC correction unit 4, DC/DC unit 5 all to quit work.
Although now b power supply 17 passes through Power Management Unit 15 provides working power to microprocessor unit 9, keyboard unit 6, display unit 7, switch element 8 and WIFI module 10.Input voltage measurement sensor 11；DC/DC unit output voltage current detection sensor 12；AC-input voltage detection sensor 14 is all passive sensor, in this case, they still work, and microprocessor unit 9, keyboard unit 6, display unit 7, switch element 8 and WIFI module 10 have working power, the data of collection still uploads to microprocessor unit 9
But while remote switch 18 is in opening, the auxiliary contact of remote switch 18 will export a signal to microprocessor unit 9, running software program can be switched to telework state after receiving this signal by microprocessor unit 9, under this working condition, the I/O1-----I/O7 mouth of microprocessor unit 9 is by dormancy.
When when remotely needing start, as starting-up signal is sent using mobile phone, by network and wireless router, communicated with microprocessor unit 9 by WIFI module 10 again, after the I/O10 mouth of microprocessor unit 9 receives signal processing, send action command and remote switch 18 shutoff is in normally off, the auxiliary contact of remote switch 18 will export a signal to microprocessor unit 9, running software program can be switched to normal operating conditions after receiving this signal by microprocessor unit 9, under this working condition, breaking dormancy is recovered normal by the I/O1-----I/O7 mouth of microprocessor unit 9, its working condition flow process is as previously described.
