The operation principle of the refrigerator open energy-conservation reminding module：T from primary voltage is 22OV, secondary voltage is a 7V left sides Right power transformer.VD selects 1A/50V rectifying full bridge, it is also possible to which whole commutation diode forms bridge rectifier generation With.NE555 time-base integrated circuits can be selected in IC1.IC2 selects HFC5203 type speech synthesis ics, one " quick closing valve of internal memory Door " language, its tone are relevant with outward element R6, C4 numerical value.When C4 selects 360PF, it is female voice " fast to close the door " language, increases When big C4 is 560PF, just it is changed into male voice " fast to close the door " language, continues to increase C4 capacity, may occur in which old male voice " fast to close the door " Language.IC3 is from TWH68 types boosting power amplifier solid-state circuit.YWH15 is high loudness piezoelectric ceramics alarming horn.During switch time delay Between setting, can suitably adjust adjustable resistance RP acquisition.RP resistance is 58K Ω.Just it is delayed 30 seconds, ICI pin 3 is just by original The low level come is changed into high level, and loudspeaker send the language of " fast to close the door ", and adjustment comes to an end.

Once refrigerator doors are opened, magnetic switch S closures, bulb H is with regard to bright, and the full primary coil of power transformer is powered, warp 7V alternating voltages are exported from secondary coil after decompression, this voltage filters through full-bridge VD rectifications, C1 again, is changed into 6V or so direct current Supply circuit is pressed to use.When switching on power, just there is electric current to be charged through RP to C2, the pin 2 and the current potential of pin 6 for causing IC1 gradually reduce, After 1.1Rp*C2 is delayed, IC1 pin 3 is changed into high level from original low level, the energization work of language IC 2, The speech signal of " fast to close the door " is exported by 0/P ends.Due to the sound very little directly exported by IC2 0/P ends, therefore employ boosting Power amplifier solid-state circuit TWH68 and high sound alarm loudspeaker YWH15.Meanwhile detect pin 3 with the main control module that IC1 pin 3 are connected Wireless transport module transmission information to mobile terminal, mobile terminal communication is controlled to be connected to remote control terminal after level change, Finally, monitoring personnel can learn the warning message that refrigerator doors are not closed.If refrigerator doors are closed, the level of pin 3 changes, and controls terminal Receive all clear information.

The operation principle of the outage condition detection alarm module：The input of optical coupling isolator is connected directly between refrigerator Power supply branch circuit is for example power supply voltage stabilizing chip in refrigerator warning system in power-supply circuit or power circuit branch Place branch road, when not having a power failure, optical coupling isolator is worked, and the voltage on resistance R2 is cut close to FET Vdd, FET Only, warning device buzzer does not work.Electric capacity is used for the voltage for stablizing fet gate, prevents alternating voltage zero-crossing from making grid Voltage change is too big and produces malfunction.When power circuit or power branch power off, optical coupling isolator does not work, FET Conducting, buzzer are started working.When power circuit or power supply branch circuit power off, it starts to alarm, and is easy to personnel to find disconnected Electric branch simultaneously repairs to deenergizing circuit.And circuit structure is simple, cost is cheap, it is easy to accomplish.The resistance R3 and drain electrode Connected one end is also connected with main control module；The low and high level whether FET turns on the tie point changes therewith, master control mould The I/O mouths of block are by detecting whether the level i.e. can be known powers off.To be known in the art, the outage detection alerts mould The power supply for the chip needs that block, door energy-saving reminding module, main control module and overtemperature detection module are related to is after ensuring power-off Normal work, provided by battery.This part is this area routine techniques, does not add to repeat herein.Moreover, this outage detection module Also can be multiple according to needing to install, one is respectively set in the multiple branch roads for needing to detect, so, can when there is open circuit conditions generation Advantageously and intuitively investigate which partial power branch road there is a problem.

It is understood that above with respect to specific descriptions of the present utility model, it is merely to illustrate the utility model and is not The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with The utility model is modified or equivalent substitution, to reach identical technique effect；As long as satisfaction uses needs, all in this reality Within new protection domain.
