Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, the present invention, for the Electric Power Data Collector of Automatic meter reading system, comprising: central processing unit, wireless meter-reading module, power carrier module, RS485 interface, and memory.Wherein,
Central processing unit, its respectively with wireless meter-reading module, power carrier module, RS485 interface, and memory connects, for carrying out the mutual conversion of power carrier agreement and wireless protocols and the management of electric energy meter data (storing memory into by electric energy meter data), central processing unit adopts high-performance processor STM32F103ZGT6.
Wireless meter-reading module, for realizing radio meter register agreement, access radio meter register network, realizes the communication of central processing unit and radio meter register concentrator, and this example adopts the WIA wireless meter-reading module of Shenyang Inst of Automation, Chinese Academy of Sciences's development;
Power carrier module, for realizing power carrier agreement, is connected with central processing unit by serial ports, and for the communication of central processing unit and power carrier concentrator, this example adopts the single-phase carrier communication module PLCS1641 of Qingdao Neusoft;
RS485 interface, for the exchanges data of central processing unit and external equipment;
Memory, for storage program and data, program storage uses the dataflash of 8M, and data storage uses 64M SDRAM, can insert in addition SD card.
The operation principle of collector and workflow:
The function that this collector is realized power carrier electric energy meter access WIA radio meter register network, realizes power carrier electric energy meter and passes mutually to the data of WIA radio meter register concentrator.Power carrier module is used the single-phase carrier communication module PLCS1641 of Qingdao Neusoft, moves the autonomous protocol stack of power carrier above it, can communicate by letter with power carrier electric energy meter.What WIA wireless meter-reading module adopted is the WIA radio meter register agreement of Shenyang Inst of Automation, Chinese Academy of Sciences's exploitation, for accessing WIA radio meter register network, realizes the radio communication of this collector to WIA radio meter register concentrator.
