Description of drawings
Fig. 1 is the enforcement illustration of the utility model hardware configuration.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, the utility model is used 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 storer.Wherein,
Central processing unit, its respectively with wireless meter-reading module, power carrier module, RS485 interface, and storer connects, be used for carrying out the mutual conversion of power carrier agreement and wireless protocols and the management of electric energy meter data (be about to the electric energy meter data and store storer into), central processing unit adopts high-performance processor STM32F103ZGT6.
Wireless meter-reading module is used for realizing the radio meter register agreement, and access radio meter register network is realized 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;
The power carrier module is used for realizing the power carrier agreement, is connected with central processing unit by serial ports, is used for the communication of central processing unit and power carrier concentrator, and this example adopts the single-phase carrier communication module PLCS1641 of Qingdao Neusoft;
The RS485 interface is for the exchanges data of central processing unit and external unit;
Storer is used for storage program and data, and program storage uses the dataflash of 8M, and data-carrier store uses 64M SDRAM, can insert the SD card in addition.
The principle of work of collector and workflow:
The function that this collector is realized power carrier electric energy meter access WIA radio meter register network realizes that the power carrier electric energy meter passes mutually to the data of WIA radio meter register concentrator.The power carrier module is used the single-phase carrier communication module PLCS1641 of Qingdao Neusoft, and the autonomous protocol stack of operation power carrier can be communicated by letter with the power carrier electric energy meter above it.What the WIA wireless meter-reading module adopted is the WIA radio meter register agreement of Shenyang Inst of Automation, Chinese Academy of Sciences's exploitation, is used for access WIA radio meter register network, realizes that this collector is to the radio communication of WIA radio meter register concentrator.
