Description
Technical field
The utility model belongs to the power industry automation control area, is specifically related to a kind of radio ammeter data acquisition unit that traditional ammeter is simply transformed.
Background technology
Flourish along with Chinese government utility, common people have higher requirement to living environment and quality thereof, so intelligent residence equipment arises at the historic moment.As the necessaries in the intelligent residence, intelligent meter data recording system has obtained flourish.Time-consuming, the effort of traditional manual meter reading method, accuracy and promptness can not get guarantee, and the person of checking meter and some offending difficult situations of user can occur, cause the user not report, lie about, and then make the statistics of data to carry out.
Along with carrying out of China's industrial system continuous development of the reform and electric network reconstruction engineering comprehensively, traditional manual meter reading method can not adapt to power department modernization and informationalized requirement.For satisfying the needs of electric network reconstruction, the wireless automatic meter recording system that cost is low, efficient is high, real-time becomes the first-selection of power department.At present, the intelligent construction of the electrical network of country is to replace traditional ammeter with the intelligent integral ammeter to cooperate wireless module to carry out automatic data logging, but make the electric network reconstruction cost very high to whole replacement of traditional ammeter, the electric network reconstruction construction difficulty of serious waste of resources, particularly vast rural area is big especially.Therefore need a kind ofly can simply transform the intelligent electric meter that just can realize that ammeter data is gathered at traditional ammeter.
Summary of the invention
At the cost height that exists in the prior art, the big problem of transformation difficulty, the utility model provides a kind of cost low, radio ammeter data acquisition unit simple in structure.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of radio ammeter data acquisition unit, comprise display module, photographing module, single-chip microcomputer, radio-frequency (RF) receiving and transmission module and power module, described power module is respectively to single-chip microcomputer and radio-frequency (RF) receiving and transmission module power supply, described photographing module is taken pictures to display module, the photographing module output terminal connects the single-chip microcomputer input end, the single-chip microcomputer output terminal connects the radio-frequency (RF) receiving and transmission module input end, and radio-frequency (RF) receiving and transmission module sends to data concentrator with data with wireless mode.
Adopt the utility model of technique scheme, by at traditional ammeter picture pick-up device being installed, electric weight demonstration numeral is taken pictures, the picture that obtains is handled by single-chip microcomputer, data after by radio-frequency (RF) receiving and transmission module single-chip microcomputer being handled then send to data concentrator, thereby realize the automatic collection of ammeter data.
Further, in order further to reduce cost and to improve system response time, described photographing module adopts the imageing sensor based on CMOS, and this type of sensor is low in energy consumption, and its resolution can satisfy the basic demand of various image recognition algorithms.
The utility model carries out image recognition acquisition ammeter counting by the picture that camera obtains the ammeter counting is installed thereby this picture uploads to data concentrator after treatment.This system equipment not only overcomes the problem of traditional write by hand ammeter difficulty, and has avoided transforming or replacing traditional ammeter is complicated, is specially adapted to the electric network reconstruction of vast rural area.
Description of drawings
Fig. 1 is the utility model radio ammeter data acquisition unit structural representation.
Embodiment
In order to make those skilled in the art understand the utility model better, below in conjunction with drawings and Examples technical solutions of the utility model are further specified.
As shown in Figure 1, a kind of radio ammeter data acquisition unit comprises display module, is used for showing ammeter electric weight counting; Photographing module is taken pictures to the electric weight counting of display module; Single-chip microcomputer is handled the picture of photographing module output; Radio-frequency (RF) receiving and transmission module sends to data concentrator with the image data after handling with wireless mode; Power module is used for to photographing module, single-chip microcomputer and radio-frequency (RF) receiving and transmission module power supply, and described photographing module adopts the imageing sensor based on CMOS.
Concrete workflow is as follows: receive when collector to enter duty after the data acquisition of concentrator is instructed, this moment, photographing module was taken pictures to the electric weight counting of display module, the image data that obtains carries out respective handling by single-chip microcomputer, image data after the processing sends to data concentrator by radio-frequency (RF) receiving and transmission module with the form of wireless signal, realizes the automatic collection of ammeter data.
Photographing module adopts the OV7620 imageing sensor, and this sensor bulk is little, and response speed is fast, and is low in energy consumption, low price, and 664 * 492 resolution can satisfy the requirement of image recognition fully.Radio-frequency (RF) receiving and transmission module sends and embeds user profile and encrypted authentication information in the data, and user profile can be corresponding one by one with the collector numbering, makes the transmission of data more safely with stable by CRC check.The little process chip of C8051F41x that single-chip microcomputer adopts SiliconLab company to release, this chip encapsulation is little, performance is high, low in energy consumption, can further reduce the loss of power of collector, the serviceable life of improving system.
The utility model carries out image recognition acquisition user electric weight by the picture that camera obtains the traditional ammeter amount of powering on counting is installed thereby send to data concentrator after treatment.This system equipment not only overcomes the problem of traditional write by hand ammeter difficulty, and has avoided complexity transformation or replacement to traditional ammeter, is specially adapted to the electric network reconstruction of vast rural area.
More than radio ammeter data acquisition unit that the utility model is provided be described in detail.The explanation of specific embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
