Technical field
The utility model relates to a kind of electric energy metering device, relates to a kind of Network Bridge Electric Energy Meter specifically.
Background technology
Used electric energy meter is independently of one another between each communication port though major part has two or more communication interfaces at present, can not realize interconnecting.Because the unified electric energy meter communication protocol of using of present homemade ammeter, only defined the standard of infrared and RS485 communication interface and do not defined the communication interface standard of power line carrier.The carrier power meter (electric energy meter with electric line carrier communication function) that each producer's design is produced is because each producer adopts different technical methods to realize electric line carrier communication, also do not form unified standard at present, there is not current standard in the world yet, so can not intercommunication between the carrier power meter of different manufacturers and the kilowatt meter reading-out system, thereby making the user be difficult in an area uses simultaneously from the carrier power meter of different manufacturers and forms kilowatt meter reading-out system, this can not satisfy user's the demand and the trend of power system development.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of Network Bridge Electric Energy Meter is provided, and each communication port both can work alone, and also can transmit mutually, realizes interconnecting.Can be linked into the electric line carrier communication channel from the ammeter communication interface (channel) of standard.
The technical solution of the utility model is: a kind of Network Bridge Electric Energy Meter, constitute by ammeter collecting part and dedicated processes module, it is characterized in that having simultaneously power line carrier, RS485 and infrared three communication interfaces, and electric line carrier communication and RS485 communication, infrared communication be bridge joint mutually, forms bridge.
Above-mentioned Network Bridge Electric Energy Meter, it is further characterized in that described dedicated processes module is integrated with clock, AD converter, wave filter, non-volatile data memory, communication network bridge-set, and that described communication network bridge-set can be supported is infrared, the access of any communication modes among RS485 and the PLC (power line carrier).
Above-mentioned Network Bridge Electric Energy Meter, be characterised in that further described dedicated processes module also is integrated with two asynchronous serial communication interfaces (UART) and relaying communication device, described asynchronous serial communication interface can be used for infrared, RS485 communication, and described relaying communication device can be used as the RS485 of other table or the relaying of PLC communication.
Network Bridge Electric Energy Meter beneficial effect of the present utility model is that electric energy meter has the special carrier communication module, and electric line carrier communication and RS485 communication, infrared communication be bridge joint mutually, forms bridge.Integrated clock, AD converter, non-volatile data memory in the module can satisfy common list/three-phase table, the many rate scales of list/three-phase of most of areas band communication functions, the requirement of list/three-phase carrier wave meter.By bridge and power line communication function, can compatible easily various automatic meter reading systems.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail as follows:
A kind of Network Bridge Electric Energy Meter, as shown in Figure 1, 2, the dedicated processes module is made up of special chip and peripheral interface device, and wherein 2 UART (asynchronous communication mouth) can be respectively applied for RS485 communication and infrared communication interface.Electric line carrier communication interface and RS485 communication interface, the mutual bridge joint of infrared communication interface are formed bridge.Integrated clock, ADC, nonvolatile memory in the dedicated processes module can satisfy common list/three-phase table, the many rate scales of list/three-phase of most of areas band communication functions, the requirement of list/three-phase carrier wave meter.By bridge and power line communication function, can compatible easily various automatic meter reading systems.
The characteristics of electric line carrier communication:
Inner integrated power line carrier communication modulation module cooperates a spot of peripheral circuit, can form PLC (power line carrier) telecommunication circuit.The modulation module adopts FSK natural code modulation system, frequency 200kHz.Solidify carrier-current relaying functional software module in the dedicated processes module, can be arranged to the two-stage relaying at most.By the forwarding of relaying, the ability of the carrier communication that doubled.And on each dedicated processes module, realize owing to relay function, can select routed path very flexibly when system checks meter, improved the ability of kilowatt meter reading-out system to greatest extent.
The bridging communication function
Solidify bridging communication functional software module in the dedicated processes module, promptly can three kinds of communication networks (infrared, RS485, interconnected between PLC).Meter reading data can carry out bridge joint by any Network Bridge Electric Energy Meter between 3 kinds of communication interfaces, promptly the function of relaying is expanded to 3 passages from single passage, and select bridge path as required.
The one-level bridge, be that kilowatt meter recorder passes through infrared or RS485, utilize the technology of other Network Bridge Electric Energy Meter data of electric line carrier communication copy reading of any Network Bridge Electric Energy Meter, because its bridge path is unidirectional, the passage conversion has only been carried out once, therefore is called the one-level bridge; Bridge plays the Network Bridge Electric Energy Meter of bridge joint effect in communication, when checking meter, can select any Network Bridge Electric Energy Meter as bridge, and read the data of other Network Bridge Electric Energy Meter by this bridge;
The secondary bridge, promptly on one-level bridge basis, realized changing to RS485 from the PLC interface, infrared or the RS485 interface of kilowatt meter recorder is bridged to electric line carrier communication by one-level bridge bridge, be bridged to the RS485 interface of other ammeter again from the electric line carrier communication of secondary bridge bridge, realize the secondary conversion of passage.
Fig. 3 is the practical application circuit diagram of the utility model Network Bridge Electric Energy Meter.
Most preferred embodiment of the present utility model is illustrated, and the various variations or the remodeling of being made by those of ordinary skills all belong to protection domain of the present utility model.
