Abstract

The utility model proposes a kind of plastic optical fiber M Bus bus conversion devices, including：One housing, it is the cuboid with an opening；One dismountable door cover plate, is engaged with the housing, and for closing the opening, it has at least optical-fibre communications inlet and outlet and M Bus buses inlet and outlet；And a PCBA, for realizing the conversion between plastic optical fiber signal and M bus bus signals.The instrument of M Bus EBIs can be accessed by plastic fiber communication system with very convenient be reliably achieved.

Description

A kind of plastic optical fiber M-Bus bus conversion devices

Technical field

It the utility model is related to meter reading field, more particularly to a kind of plastic optical fiber Mbus bus conversion devices.

Background technology

In order to establish conservation-minded society, national correlation department is widelyd popularize four tables (water, electricity and gas heat) set and copied and accepted.Four During table collection is copied, the remote copying system of ammeter data is the most universal and extensive, in the remote copying system of ammeter, plastic optical fiber For this Novel environment-friendlymaterial material because environment electromagnetics compatibility is good, real-time communication is reliable and stable, and installation safeguards that debugging is easy, in meter reading Field shows the trend caught up from behind.M-Bus is a kind of data that information is transmitted exclusively for consumption measuring instrument and counter The of bus design has many applications in building and the collection of industrial energy consumption data, is that the two of 2 lines of European standard are total Line.

At present on the market by the conversion of M-Bus buses and other communication medias mainly in power carrier communication, copper communication （RS232 cables, can buses, 485 twisted-pair feeders etc.）, between wireless telecommunications etc., yet there are no and lead to M-Bus buses in plastic optical fiber Conversion between news.

It is more to have social value and realistic meaning in fact, Mbus bus communications are combined with plastic fiber communication.

Utility model content

How that M-Bus bus communications and plastic fiber communication is whole key technical problem to be solved in the utility model is End organically combines, and so as to propose a kind of plastic optical fiber M-Bus bus conversion devices, can be reliably achieved with very convenient by M- The instrument access plastic fiber communication system of Bus EBIs.

The utility model proposes a kind of plastic optical fiber M-Bus bus conversion devices for above-mentioned technical problem, including：One shell Body, it is the cuboid with an opening；One dismountable door cover plate, is engaged with the housing, and for closing the opening, it has There are at least optical-fibre communications inlet and outlet and M-Bus buses inlet and outlet；And a PCBA, for realizing plastic optical fiber signal and M- Conversion between bus bus signals.

Wherein, together with the housing is installed with the door cover plate by the way of fastening.

Wherein, the door cover plate also has supply main inlet and outlet.

Wherein, the PCBA has CPU processing functions circuit, optical fiber receiver-transmitter module and M-Bus functional modules.

Wherein, the PCBA also has communication indicator function circuit.

Compared with prior art, plastic optical fiber M-Bus bus conversion devices of the present utility model, by dexterously shell Body, door cover plate and PCBA are grouped together, and the instrument of M-Bus EBIs can be accessed into modeling with very convenient be reliably achieved Expect Fiber Optical Communication System.

Brief description of the drawings

Fig. 1 is body diagram of the present utility model.

Fig. 2 is door cover plate schematic diagram of the present utility model.

Fig. 3 is PCBA schematic diagrames of the present utility model.

Wherein, description of reference numerals is as follows:It is total that 22 Mbus are imported and exported in opening 2 door cover plate 21 optical-fibre communications of 1 housing 11 Line imports and exports the Mbus functional modules of 3 PCBA, 31 32 optical fiber receiver-transmitter modules of CPU processing functions circuit 33.

Embodiment

Below in conjunction with accompanying drawing, specific implementation of the present utility model is given illustrating more in detail.

Referring to Fig. 1 to Fig. 3, Fig. 1 is body diagram of the present utility model.Fig. 2 is door cover plate signal of the present utility model Figure.Fig. 3 is PCBA schematic diagrames of the present utility model.The utility model proposes a kind of plastic optical fiber M-Bus bus conversion devices, its Including：One housing 1, it is the cuboid with an opening 11；One dismountable door cover plate 2, is engaged with the housing 1, is used for The opening 11 is closed, it has at least optical-fibre communications inlet and outlet 21 and M-Bus buses inlet and outlet 22；And a PCBA 3, For realizing the conversion between plastic optical fiber signal and M-bus bus signals.

In the present embodiment, together with the housing 1 is installed with the door cover plate 2 by the way of fastening.The door cover plate 1 also has There are supply main inlet and outlet.The PCBA 3 has CPU processing functions circuit 31, optical fiber receiver-transmitter module 32, M-Bus functional modules 33 and communication indicator function circuit（It is not shown）.

Compared with prior art, plastic optical fiber M-Bus bus conversion devices of the present utility model, by dexterously housing 1st, door cover plate 2 and PCBA 3 are grouped together, and can be reliably achieved with very convenient by the instrument access of M-Bus EBIs Plastic fiber communication system.
