Abstract
The utility model provides a data transmission module for a power collector. The data transmission module comprises a GPRS (General Packet Radio Service) module connected with a plurality of electricity meters through RS485 interfaces, and the GPRS module integrates the DL/T645-1997 and DL-T645-2007 meter reading protocol in national power industry and the Q/GDW_376.1-2009 'the communication protocol of electricity utilization information acquisition system for power consumers: the communication protocol of the master station and the acquisition terminal', has the meter reading and data uploading functions, and is also connected with an LED indicator light, a keystroke and an infrared port. The data transmission module for the power collector has the advantages that a data concentrator is omitted, unreliability of power line transmission is avoided, and a power data acquisition module, a power data storage module and a power data transmission module are integrated, so that the power acquisition system has a simpler structure and is more reliable in data transmission.
Description
Technical field
The utility model relates to the combination of a kind of Electric Power Data Collector and electric power data transmission unit, belongs to wireless communication field.
Background technology
The power information of existing Utilities Electric Co. system acquisition power consumer is the power information of gathering electronic electricity meter by data acquisition unit, be wirelessly transmitted to data concentrator by power line or micropower, data concentrator is transferred to the management server of power marketing system again by public phone network, as shown in Figure 1.Because present technology limits, the power line transmission data exist anti-interference poor, and decay is serious, and channel parameter changes the fast transmission quality that causes data that waits and can not get guaranteeing.
As shown in Figure 2, the available data collector all adopts the mode of " high-performance MCU Main Processor Unit (data acquisition and storage)+communication module ".Because communication module separates with the Main Processor Unit formula, institute in this way cost than higher.And master controller (MCU) and memory are also arranged in the communication module, so on resource repetition.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of electric power acquisition device data transmission module is provided, main control module as acquisition terminal, it is integrated electric power acquisition agreement and electric power data host-host protocol on the GSM/GPRS module basis, cooperation just can directly be copied and accepted the data of ammeter by the serial ports of module with the interface circuit of necessity, and can be with the electricity consumption transfer of data to the main website of Utilities Electric Co. by the GPRS channel.
The technical scheme that provides according to the utility model, described electric power acquisition device data transmission module comprises the GPRS module, described GPRS module connects a plurality of ammeters by the RS485 interface, the GPRS module is integrated DL/T 645-1997 and the DL-T 645-2007 State Grid industry agreement of checking meter, and Q/GDW_376.1-2009 " power consumer power information acquisition system communication protocol: main website and acquisition terminal communication protocol ", described GPRS module possesses simultaneously checks meter and the data upload function, also is connected with LED light, button and infrared port.
Described GPRS module adopts Shanghai Simcom SIM300W P1604B03SIM300W128 module.
The utility model has the advantages that: compare the conventional powerline transmission means, data concentrator has been saved in the appearance of this module, avoided the unreliability of power line transmission, realized collection, storage, transmission module-integrated of electric power data, make that the formation of electric power acquisition system is simpler, transfer of data is more reliable.ICP/IP protocol is adopted in the GPRS transmission, and data transmission credibility greatly improves, and system constitutes cost and greatly reduces.
