Advantage of the present utility model: the electrical energy metering tank with anti-stealing electricity function described in the utility model improves on the basis of existing equipment, simple and reliable for structure, can report to the police once there is unpacking action, and remote reporting supvr, electricity filching behavior is eliminated in bud.
Accompanying drawing explanation
Fig. 1 is the structural representation with the electrical energy metering tank of anti-stealing electricity function described in the utility model.
Embodiment
Embodiment one: present embodiment is described below in conjunction with Fig. 1, has the electrical energy metering tank of anti-stealing electricity function described in present embodiment, it comprises microprocessor 1, SMS module 2 and unpacking detecting unit 3; The unpacking signal output part of detecting unit 3 of unpacking is connected with the unpacking signal input part of microprocessor 1, the instruction output end of microprocessor 1 is connected with the command input of SMS module 2, and unpacking information is sent to designated mobile phone terminal with note form by antenna by SMS module 2; + 6V direct supply is powered for microprocessor 1 and unpacking detecting unit 3 simultaneously;
Detecting unit 3 of unpacking comprises NE555 time-base integrated circuit, miniature elastic button SN, resistance R1, resistance R2, slide rheostat Rp1, electrochemical capacitor C1, electric capacity C2, diode D1, NPN triode VT1, auxiliary reclay KA and loudspeaker BL; Miniature elastic button SN is arranged on the chamber door of batch meter, and when chamber door closes, miniature elastic button SN is off state; When chamber door is opened, miniature elastic button SN is closure state;
+ 6V direct supply connects the positive pole power supply terminal of the stiff end of slide rheostat Rp1 and movable end thereof, one end of resistance R1, one end of resistance R2,4 pin of NE555 time-base integrated circuit, 8 pin and loudspeaker BL simultaneously;
Another stiff end of slide rheostat Rp1 connects one end of miniature elastic button SN and the base stage of NPN triode VT1 simultaneously; The collector other end of contact resistance R1 and 2 pin of NE555 time-base integrated circuit simultaneously of NPN triode VT1; 7 pin of NE555 time-base integrated circuit connect self 6 pin, the other end of resistance R2 and the positive pole of electrochemical capacitor C1 simultaneously; 5 pin of NE555 time-base integrated circuit connect one end of electric capacity C2; 3 pin of NE555 time-base integrated circuit connect the negative pole of diode D1, one end of auxiliary reclay KA coil and the unpacking signal input part of microprocessor 1 simultaneously; One end of auxiliary reclay KA normally opened contact connects the negative pole power supply terminal of loudspeaker BL;
The power supply ground end of microprocessor 1 connects the other end of the other end of auxiliary reclay KA normally opened contact, the other end of auxiliary reclay KA coil, the positive pole of diode D1,1 pin of NE555 time-base integrated circuit, the other end of electric capacity C2, the negative pole of electrochemical capacitor C1, the emitter of NPN triode VT1 and miniature elastic button SN simultaneously, and ground connection.
