Abstract
A novel M-Bus bus intelligent telemetering water meter, comprise modified M-Bus from dynamo-electric road, modified base table, waterproof Bussing connector sum counter.Modified base table is that dry type magnetic passes structure, for M-bus operation carrier is provided, counter adopts photoelectric code disk direct reading structure, the total new connector of waterproof is connected with from dynamo-electric road, fixed by screw clip with modified base table, the total new head link actuator of waterproof adopts dock screw threads for fastening and silicone rubber seal coil structures.The utility model by table end from the improvement on dynamo-electric road, the upgrading of bus connection wire, the multiplication strains of base table, the shortcoming such as overcome water meter terminal circuit fault that such water meter existing occurs in actual application, communication speed is low, communication apparatus capacity is little.
Description
Technical field
The utility model relates to a kind of intelligent telemetering water meter, is specifically related to a kind of novel M-Bus bus intelligent telemetering water meter.
Background technology
Civil remote water meter wired at present mainly contains RS485 bus and M-Bus bus type two kinds.Wherein RS485 bus remote transmitting water meter use amount slowly reduces, and can not meet the needs of Large Copacity centralized automatic meter-reading network, there is following problem in application process:
1. the communication apparatus capacity of RS485 is few, allows at most that access amount is no more than 128 equipment in theory, and this is not obviously be multi-user's capacity requirement of node in order to building;
2.the communication speed of RS485 is low, and its speed and communication distance have direct relation, when reaching the above communication distance of hundreds of rice, and its reliable communicating speed <1200bps, this makes the speed of checking meter of great deal of nodes very low;
3. RS485 mode powers to down the equipment of connecing, and equipment needs to solve powerup issue separately;
4. the network formed with RS485 can only with tandem routing, any branches such as star can not be formed, and tandem routing causes great difficulty for the practical wiring design and construction of community, do not follow tandem routing rule and will greatly reduce the stability of communication again, and the electrical property due to RS485 self determines its less stable in practical engineering application, and the debugging of multinode, long distance needs to carry out the debugging efforts such as impedance matching to circuit, during a large amount of installation, debugging efforts is complicated.
Use M-bus bus remote transmitting water meter, it has easy-to-connect, long transmission distance, and load capacity is comparatively strong, saves the advantage of manpower, material input.But due to the improper use of M-bus water meter in concrete application process, cause M-bus water meter terminal circuit fault, the table of whole bus cannot be copied and accepted.
Utility model content
For the problems referred to above, the utility model provides a kind of novel M-Bus bus intelligent telemetering water meter, its object is to: the communication shortcoming overcoming RS485, guarantee the communication speed that high speed is stable, extremely low quiescent dissipation, reduce the failure rate of M-bus water meter terminal circuit, and other water meters of affecting on whole communication bus after breaking down, can not be caused.
Technical solution of the present utility model:
A novel M-Bus bus intelligent telemetering water meter, is characterized in that: comprise modified M-Bus from dynamo-electric road, modified base table, waterproof Bussing connector sum counter.Described modified base table is that dry type magnetic passes structure, for described M-bus provides operation carrier, described counter adopts photoelectric code disk direct reading structure, the total new connector of described waterproof is connected with from dynamo-electric road, fixed by screw clip with described modified base table, the total new head link actuator of described waterproof adopts dock screw threads for fastening and silicone rubber seal coil structures.
Described M-Bus forms from dynamo-electric routing current dynamic compensation protection module, instantaneous pressure protection module, anti-internal current recoil module, photoelectricity correlation code-disc and single-chip microcomputer.
Described waterproof Bussing connector adopts the rapid abutting joint head of integrated injection molding, is furnished with rubber seal.
Described counter adopts rubber ring and threaded sealing structure.
The beneficial effects of the utility model:
The utility model by table end from the improvement on dynamo-electric road, the upgrading of bus connection wire, the multiplication strains of base table, the shortcoming such as overcome water meter terminal circuit fault that such water meter existing occurs in actual application, communication speed is low, communication apparatus capacity is little.
Accompanying drawing explanation
Fig. 1: the utility model water meter is from machine circuitry figure.
Fig. 2: the utility model water meter is from dynamo-electric flowable state compensating circuit module and anti-internal current recoil module.
Fig. 3: the utility model water meter circuit instantaneous pressure protection module.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
A kind of novel M-Bus bus intelligent telemetering water meter as shown in Figure 1 to Figure 3, comprise modified M-Bus from dynamo-electric road, modified base table, waterproof Bussing connector sum counter, described waterproof Bussing connector adopts the rapid abutting joint head of integrated injection molding, is furnished with rubber seal, described modified M-Bus comprises electric current dynamic compensation protection module from dynamo-electric road, instantaneous pressure protection module, anti-internal current recoil module, photoelectricity correlation code-disc and single-chip microcomputer, described modified base table adopts dry type magnetic to pass structure, described character wheel of counter has notch, described counter adopts rubber ring and threaded sealing structure.
The utility model can overcome the communication shortcoming of RS485, guarantee the communication speed that high speed is stable, extremely low quiescent dissipation, simultaneously modified M-Bus can reduce the failure rate of M-bus water meter terminal circuit from dynamo-electric road and modified base table, and can not cause other water meters of affecting on whole communication bus after breaking down.
To sum up, the utility model accomplishes the end in view.
