Automatically copy and accept the detector of dwelling house energy consumption

The utility model relates to a kind of device of copying and accepting power consumption, water consumption, air consumption on residential customer ammeter, water meter, the gas meter automatically that is installed in.

Along with the improvement of people's living conditions, a large amount of construction of high-rise, centralized residential building, in the past power consumption, water consumption, air consumption with manual metering record residential customer are far from suitable, and manual metering intensity is big, and speed is slow, inconvenient energy management division management.

In view of this, the purpose of this utility model provides a kind of detector of copying and accepting the dwelling house energy consumption automatically, and it can constantly provide energy consumption information, is automatic data logging by the variable manual metering of this detector, to reduce labor intensity, improves work efficiency.

Technical solution of the present utility model is: the ingredient that is installed in the detector on user's energy-consuming meter comprises probe, binary counter, binary coding circuit, on-off circuit and signal sampling circuit, wherein probe is to be made of the magnet of device on the energy-consuming meter rotary part and the rest switch that is fixed near rotary part, rest switch can be used mechanical switch, as tongue tube, also can use electronic switch, as Hall, when magnet forwards near rest switch to rotary part, switch is subjected to magneticaction just closed, by binary counter the pulse signal of input is counted, its output terminal links to each other with binary coding circuit, this binary coding circuit is to be formed by resistance and diode combinations, when the pulse binary counting of counter is consistent with the binary coding of coding circuit, be connected to the on-off circuit conducting of binary coding circuit output terminal, this moment, the output signal of coding circuit was synthetic with the sampled signal from probe through on-off circuit entering signal sample circuit, output then, when the probe switch closure the time, synthesized output signal is a low level, when the probe switch opens the time, synthesized output signal is a high level.During work, detector is constantly accepted pulse signal, according to the switch closure of probe or the sample states of opening, constantly output changes high by low again, the level signal of changeing low by height changes, accumulate this level signal and change the quantity that just can know actual energy consumption, this shows that detector of the present utility model can be used for copying and accepting automatically the dwelling house energy consumption.Usually, can adopt 8098 single card microcomputers to send pulse and finish the accumulation that high and low level output signal is changed and realize copying and accepting automatically energy consumption to detector.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the theory diagram of the utility model detector;

Fig. 2 is a kind of instantiation of the utility model detector;

Fig. 3 is the magnet installation site synoptic diagram of probe;

Fig. 4 is a holding circuit.

With reference to Fig. 1, detector is formed part and is comprised probe 5, binary counter 1, binary coding circuit 2, on-off circuit 3 and signal sampling circuit 4, pulse signal by 1 pair of input of binary counter is counted, its output terminal links to each other with binary coding circuit 2, when the pulse binary counting of counter is consistent with the binary coding of coding circuit, be connected to on-off circuit 3 conductings of coding circuit output terminal, the output signal of coding circuit is through on-off circuit entering signal sample circuit 4, and is synthetic with the sampled signal from probe 5, output then.

Fig. 2 is mounted in a kind of physical circuit example of the detector on user's energy-consuming meter.Here, binary counter 1 adopts integrated package MC14040, its 10 pin is a counting end, and 11 pin are reset terminal, and 16 pin are power input, Q1～Q12 is an output terminal, be used for counter reset by resistance R 3, diode D2, the reset circuit that capacitor C 2 constitutes, its R3, D2, C2 contact altogether link to each other R3 with 11 pin, connecting resistance R4 between another contact of D2 and 10 pin, pulse signal source links to each other with detector A point, and in illustrated example, counter uses eight output terminals of Q1～Q8, binary coding circuit 2 is to be formed by corresponding resistance and the diode combinations that is connected to eight output terminals of counter one by one, and its resistance and diode number sum equal 8.According to user's needs, by adopting different resistance, the tie point of diode number and transformation resistance and diode and counter, can make detector have different binary codings, eight of counter output terminals in this example, have the permanent connecting resistance R1 of an output terminal except that appointing, all the other 7 output terminals are connecting resistance RX or diode DX arbitrarily, but the number of RX and DX number sum are constant to be 7, like this according to resistance R X, diode DX number and RX, DX, the conversion that R1 is connected Q1～Q8 end points can obtain 255 binary codings, promptly the detector of 255 different codings is installed on respectively on 255 subscriber's meters.As RX representative " 0 ", DX, R1 represent " 1 ", and then the RX that provides by legend, DX, R1 arrange: RX, DX, RX, DX, R1, RX, RX, RX, its binary coding is 01011000B, promptly represents 88, represents detector No. 88.The on-off circuit 3 that links to each other with coding circuit is made of triode T1, T2 and resistance R 2, the end of the RX of coding circuit, DX, R1 is connected on respectively on counter output Q1～Q8, the other end splice grafting of RX is in the base stage of on-off circuit T1, and the anode of DX is connected with R1 on the line that base stage at the collector of T1 and T2 links to each other all the time.The emitter of T2 is connected on by diode D1 through resistance R 2, on the D1 anode of the signal sampling circuit 4 that light emitting diode L1 constitutes and the connecting line of L1 anode.In this example, probe 5 is made up of magnet NS and tongue tube K, magnet is installed on the rotary part of energy-consuming meter, with the ammeter is example (referring to Fig. 3), can be installed in major diameter transmits on gear 9 or the counter wheel 10 or the turbine disk 11, tongue tube is fixed near the rotary part place, make the contact in it be subjected to magnetic force adhesive or separation, a slice in the tongue tube contact links to each other with the light emitting diode L1 negative terminal of signal sampling circuit, another sheet ground connection, the negative terminal of the diode D1 of signal sampling circuit (E point) output is the detector output terminal.During work, when the binary coding of the binary counting of counter paired pulses and coding circuit is inconsistent, this moment, the base stage of T1 was a high level, current collection is low level very, T2 ends, the output of on-off circuit no signal, when the counting of counter was consistent with the coding of coding circuit, then the base stage of T1 was a low level, current collection is high level very, T1 ends, and the T2 conducting, the output signal of coding circuit is through on-off circuit entering signal sample circuit, be in attracting state as the tongue tube contact of popping one's head in this moment, signal sampling circuit output low level signal then, so at a time when the tongue tube contact be in released state, signal sampling circuit output high level signal then.
