Abstract
A double-channel collector conforming to the DLT 698 standard comprises an MCU module, a power carrier module and an RS 845 channel meter reading module, wherein the power carrier module and the RS 845 channel meter reading module are connected with the MCU module. The double-channel collector has the improvement that the collector also comprises a wireless module with wireless information transmitting and receiving functions, wherein the wireless module is connected with the MCU module. The utility model is both a collector used for collecting the data of a descending 485 energy meter, and a repeater capable of relaying data from other equipment. The double-channel collector transmits data in a power carrier manner and a wireless manner, integrates the advantages of the two manners and avoids the respective disadvantages thereof; and two channels back up each other and are of seamless transition, thereby achieving the goal that the successful meter reading rate during the period of one hour is larger than 99.9 percent.
Description
Technical field
The utility model relates to a kind of up-to-date DL/T 698 consensus standards that meet, the acquiring electric energy information concentrator that can use binary channels (power carrier passage and radio channel) to carry out data aggregation.
Background technology
According to " State Grid Corporation of China's Eleventh Five-Year Plan power marketing development plan " overall goal, marketing modernization and measurement standard its construction level have obtained quick raising, for promoting the rapid level of market response, improve the quality of customer service, implement the requirement of " lean management ", progressively set up adaptation to market variations, reflect and the marketing mechanism of customer demand must realize the real-time collection and the monitoring of power consumer power information fast, serve marketing management and every business demand conscientiously.The power information acquisition system, realize the real-time collection of important informations such as measuring apparatus on-line monitoring and customer charge, electric weight, voltage, in time, complete, provide basic data for " SG186 " infosystem exactly, thereby, promote enterprise intensification, lean and standardized management level for the analysis of each link of enterprise operation and management, decision-making provide support.
Have various power information acquisition terminals to be used to gather the data of 485 electric energy meters in the market, and arrive concentrator by certain channel transfer, general transmission channel commonly used has the narrowband carrier type, the bandwidth carrier type, radio-type.But each all has the shortcoming of oneself: the decay of narrowband carrier type is little, long transmission distance, but speed is low, is difficult to realize dynamic routing, therefore also can't realize the above-mentioned success ratio requirement of checking meter; Bandwidth carrier speed height can be realized dynamic routing, automatic relay, but transmission attenuation is fast, and distance is near, and because load is crossed conference and caused island effect, therefore also can't realize above-mentioned success ratio requirement; It is affected by environment big that the zonule is wireless, and therefore the transmission range that block, weather conditions all can influence equipment can't realize above-mentioned success ratio requirement.
Power line carrier, PLC and the radio communication of using is subjected to the influence of field condition in actual field at present.Power carrier mainly is subjected to the influence of time, because the uncertainty of load, the interference that electrical network is subjected in the section in different is different, and therefore in different, the power line carrier, PLC effect is different, and is sometimes logical, sometimes obstructed; Wireless data transmission mainly is subjected to the influence of geographical environment, the effect that block, shielding can have a strong impact on data communication, and site operation is difficulty very.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiency of existing power information acquisition terminal, and a kind of binary channels collector of the DLT of meeting 698 standards is provided, and it is to assist to carry out the transmission of power information based on power carrier passage, radio channel.
The technical scheme that its technical matters that solves the utility model adopts is as follows: the binary channels collector that meets DLT 698 standards, its composition comprises MCU module, power carrier module, RS845 passage meter-reading module, described power carrier module, RS845 passage meter-reading module are connected with the MCU module, it is characterized in that also including and possess the wireless module that wireless messages emission and wireless messages are accepted function, this wireless module is connected with the MCU module.
The beneficial effects of the utility model are as follows: the utility model is a collector, is used to gather the data of 485 descending electric energy meters; Be again a repeater, can relaying from the data of other equipment.Its first-selected electrification carrier wave communicates, when power carrier can't success communication, by near the miscellaneous equipment wireless the searching, carry out data transmission automatically by radio channel, when power-line carrier channel recovered, automatic switchover telegram in reply line of force carrier channel communicated.This binary channels collector transmits data by electrification carrier wave and wireless dual mode, combines both advantages, has avoided both shortcomings separately; Two passages backup each other, and bumpless transfer has realized the check meter target of success ratio＞99.9% of 1 hours period.
Description of drawings
Fig. 1 meets the binary channels collector structured flowchart of DLT 698 standards for the utility model.
Embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.
As shown in Figure 1, the utility model meets the binary channels collector of DLT 698 standards, its composition comprises MCU module, power carrier module, RS845 passage meter-reading module, power carrier module, RS845 passage meter-reading module are connected with the MCU module, its improvements are also to include possesses the wireless module that wireless messages emission and wireless messages are accepted function, and this wireless module is connected with the MCU module.
This binary channels concentrator is the combined type invention, the MCU module that it relates to, power carrier module, RS845 passage meter-reading module, wireless module all are existing matured product or element, and the circuit connecting relation is mutually also grasped by those skilled in the art, so the application is not described in detail the circuit structure and the concrete connected mode thereof of each ingredient.
In this binary channels concentrator, the MCU module adopts the STM32F103RB of ST company, and the power carrier module adopts the PLT050 of POEM company, isolates the MAX183 chip of 485 employing MAXIM-IC, and wireless module adopts the MC13202 chip of FREESCALE company.
