Specific embodiment

The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.

Fig. 1 is the connection diagram of egg steamer.The Live line Zero line of egg steamer all in a plug wire, by the live wire in plug wire It is therefrom separated, prompt instrument of the present utility model is arranged on the junction of plug wire on egg steamer.

Fig. 3 is structured flowchart of the present utility model.A kind of egg steamer working condition prompt instrument, it is characterised in that including inserting Head, rectifying and voltage-stabilizing module, signal acquisition module, MCU module, prompting module, AD conversion module, power module, the plug One end electrically connects with the socket electrical connection being engaged, the other end of the plug with the input of the rectifying and voltage-stabilizing module, institute State the output end of rectifying and voltage-stabilizing module, the output end of the signal acquisition module to be electrically connected with the AD conversion module respectively, institute State AD conversion module to be electrically connected with the MCU module, the MCU module is electric with the power module, the prompting module respectively Connection.

The AD conversion module uses ambipolar AD7656 chips, and by voltage, this analog quantity is converted to digital quantity, gives MCU module.

The MCU module uses single-chip microcomputer.According to fixed operating process, the signal for the treatment of AD7656 chip outputs will Work order is sent to prompting module.The model STC89C52 single-chip microcomputers of the single-chip microcomputer.

The prompting module uses buzzer, receives single-chip microcomputer and sends instruction, and buzzer sends sound and is used as alarm.It is described The model HYE1206-05 of buzzer.

The signal acquisition module uses current transformer.Primary side high current is converted into secondary low current, is conveniently carried out Whether there is electric current in measurement plug wire.The model DHC01AD1 of the current transformer.

Fig. 4 is the circuit connection diagram of rectifying and voltage-stabilizing module of the present utility model.The rectifying and voltage-stabilizing module include transformer, Electrochemical capacitor, voltage stabilizing chip LM7912CT, voltage stabilizing chip LM7812CT, rectifier bridge, the transformer and the two of the rectifier bridge Individual bridge wall is in series, the another two bridge wall of the rectifier bridge respectively with electrochemical capacitor, voltage stabilizing chip LM7912CT and voltage stabilizing chip LM7812CT is in parallel.By the alternating current of 220V it is scaled after, then be rectified into direct current, be then AD7656 cores after voltage stabilizing Piece is powered.

The voltage of the power module is 5V, for being powered to single-chip microcomputer.

Fig. 2 is scheme of installation of the present utility model.By in the plug insertion socket of prompt instrument of the present utility model, 220V Voltage is AD7656 chip power supplies by rectifying and voltage-stabilizing module, and the plug of egg steamer is inserted into socket, presses prompt instrument and steaming The switch of egg device, prompt instrument and egg steamer are started working.After incubator tray heating reaches spring temperature, egg steamer is switched off, this When prompt instrument start to detect whether have electric current in plug wire, live wire passes through current transformer DHC01AD1, by by the plug wire of primary side Electric current is converted to the low current of outflow secondary, in current transformer DHC01AD1 output ends resistance R in parallel, an output termination Ground（Such as Fig. 5）Current mode analog quantity is converted to voltage-type analog quantity, voltage analog is converted to by number by AD7656 chips Word amount, and give STC89C52 single-chip microcomputers.If there is electric current to flow through in plug wire, now STC89C52 single-chip microcomputers send instruction, honeybee Ring device HYE1206-05 starts alarm, reminds people to pull out power supply in time, prevents incubator tray from secondary dry combustion method occur.If do not had in plug wire There is electric current to flow through, then buzzer HYE1206-05 does not send sound.

The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model know-why is not departed from, some improvement and deformation can also be made, these change Enter and deform also to should be regarded as protection domain of the present utility model.
