Abstract
The utility model discloses a manual wiring device used for meter reading. The manual wiring device used for the meter reading includes a power socket D and an over-current over-voltage protection circuit. An input terminal of the power socket D is used for connecting with a communication adapter in a socket manner. An output terminal of the power socket D is connected with an input terminal of the over-current over-voltage protection circuit. An output terminal of the over-current over-voltage protection circuit is used for connecting with M-BUS water meters. The manual wiring device used for the meter reading can realize the centralized installation and meter reading of the M-BUS water meters through changing the communication adapter connected with the power socket D in the socket manner and adjusting a value of an over-current element in the over-current over-voltage protection circuit.
Description
Technical field
The utility model relates to a kind of termination, especially relates to a kind of termination of checking meter to the M-BUS water meter.
Background technology
The installation of existing M-BUS water meter is to install concentratedly, concentrates automatic data logging through the mode of directly receiving collector or concentrator.The defective that this mode of connection exists is: general M-BUS collector load capacity is more weak; Load capacity has only 4; It is then inapplicable to check meter for installing concentratedly of more M-BUS water meter; And along with the universalness of high building, the situation about installing concentratedly of a large amount of M-BUS water meters is more and more, and checking meter of how realizing therefore that more M-BUS water meter installs concentratedly is present problem demanding prompt solution.
The utility model content
The purpose of the utility model is to provide a kind of electric wire connecting junction of manually checking meter, to solve the problem of checking meter that a fairly large number of M-BUS water meter is installed concentratedly.
This electric wire connecting junction of manually checking meter that the utility model provides; Comprise a supply socket D, an overcurrent-overvoltage protecting circuit; Supply socket D input is used to the communications adapter of pegging graft; Supply socket D output is connected with the overcurrent-overvoltage protecting circuit input, and the overcurrent-overvoltage protecting circuit output is used for being connected with the M-BUS water meter.
Said overcurrent-overvoltage protecting circuit comprises TVS pipe A and protective tube B, this TVS pipe A and protective tube B series connection.
Said overcurrent-overvoltage protecting circuit comprises TVS pipe A and thermistor, and this TVS pipe A connects with thermistor.
When using, the utility model, is inserted in communications adapter in the supply socket the external M-BUS water meter of overcurrent-overvoltage protecting circuit output.During work: manually meter-copy device sends meter reading instruction; Meter reading instruction is transferred to the M-BUS water meter through communications adapter and overcurrent-overvoltage protecting circuit; The response of M-BUS water meter; Response signal is transferred to manual meter-copy device through overcurrent-overvoltage protecting circuit and communications adapter again, reads response signal by manual meter-copy device, and artificial then derived data is handled.
The beneficial effect of the utility model:
1,, can realize centralized automatic meter-reading through the transposing communications adapter because communications adapter is to be plugged in the supply socket.And be connected the quantity of M-BUS water meter on the electric wire connecting junction of manually checking meter, and be to decide by the overcurrent element in the overcurrent-overvoltage protecting circuit, therefore can realize installing concentratedly on a large scale of M-BUS water meter through the value of regulating overcurrent element;
2, can protect the M-BUS water meter of overcurrent-overvoltage protecting circuit output when supply socket misconnection 220VAC not to be damaged.When said overcurrent-overvoltage protecting circuit during, over-current over-voltage protection element responds wherein, and overflow protecting element moment is broken off, therefore guaranteed that the M-BUS water meter that is connected on the overcurrent-overvoltage protecting circuit output can not be damaged at supply socket D misconnection 220VAC;
3, only need the electric wire connecting junction of manually checking meter, just can connect many M-BUS water meters, therefore reduced cost.

Fig. 2 is the structure chart of a kind of execution mode of the utility model.
Fig. 3 is the vertical view of Fig. 2.
Embodiment
As can be seen from Figure 1 the utility model mainly is made up of overcurrent-overvoltage protecting circuit and supply socket D.Overcurrent-overvoltage protecting circuit comprises TVS pipe A and protective tube B, this TVS pipe A and protective tube B series connection.The overcurrent-overvoltage protecting circuit input is connected with supply socket D output through connecting lead C, and supply socket D input grafting communications adapter, overcurrent-overvoltage protecting circuit output are the two ends of TVS pipe A, and promptly two core terminals E are connected with the M-BUS water meter.When normally checking meter: meter reading instruction is transferred to the M-BUS water meter through communications adapter and overcurrent-overvoltage protecting circuit, the response of M-BUS water meter, and response signal is transferred to communications adapter through overcurrent-overvoltage protecting circuit again.Protective tube B in the said overcurrent-overvoltage protecting circuit can replace with thermistor.
The utility model can purchase 86 common boxes and one two core supply socket when making on market, overcurrent-overvoltage protecting circuit is made printed board, and then installation, and installation diagram is seen Fig. 2 and Fig. 3, at first with box 6 at the bottom of 86 boxes as base; Two core supply sockets 1 are installed on 86 box panels 8; Overcurrent-overvoltage circuit printing plate 4 is installed in the back side of 86 box panels 8, and printed board 4 and 86 box panels 8 are fixed through screw 2 and nut 3; Manually check meter and post the MAC Address label 7 that is associated in files on each of customers on the electric wire connecting junction; Box is fixed through screw 5 at the bottom of 86 box panels and 86 boxes.
