Description
Technical field
This patent relates to a kind of direct-reading gauge outfit that adopts camera, belongs to the survey control technology field.
Background technology
Adopt stem-winder at the most of regional civil gas managements of China at present, the gas company person of checking meter was checked meter in every month from house to house to the doorstep, and the user is according to gas consumption is paid.In whole flow process, some drawback is arranged:
1, checks meter.Increasing cell management is strengthened, and customer requirements improves, and registering one's residence checks meter produces contradictory phenomena linearly increases.Do not disturb residents in order to check meter to the doorstep, in recent years, many residential quarters have moved on to ammeter, tap water meter in the corridor in the room.But gas meter, flow meter can't solve because of safety problem, still need the person of checking meter entering check meter.For reducing " disturbing residents " number of times, meet phenomenon less than the people to the doorstep, gas company reality row checks meter every other month, estimate system such as copy, and the result is quite a few because of estimating the service dispute of copying initiation.In addition, the social idler case of pretending to be gas meter reading person to swindle to the doorstep also happens occasionally.
2, charge.Gas company is sold gas after purchasing gas earlier, and the financial pressure that causes is very big, if adopt IC-card prepaid equipment, the transmission ﹠ distribution that then can't calculate every month are poor, does not have a lot of expenses to be difficult to receive not come up simultaneously.Propose a kind of prepaid wireless remote opertaing device in this, can accomplish prepaid, can avoid again checking meter to the doorstep, the operating position in user this month is grasped in real time, be convenient to the management of gas company by radio meter register.
3, management.The level of informatization is too low, and management team is huge, does not pay dues for a long time or shows for some and go bad incalculable table, and gas company can't be controlled unique user.
Since in August, 2009, Premier Wen Jiabao proposed " perception China ", Internet of Things was formally classified as one of country's five big emerging strategic industries, writes " government work report ".The remote fuel gas meter reading system that adopts advanced technology of Internet of things to make up meets the emerging strategic industry requirement that country greatly develops.This system is made up of home intelligent wireless data sending gas meter, flow meter, wireless data sending handheld reading meter device, wireless data sending concentrator, wireless data sending repeater, wireless data sending acquisition module, multi-functional hand-held data capture management device, relevant data terminal, GPRS digital transmission module, background data center etc.
1, solves the problem of checking meter.
Home intelligent wireless data sending gas meter, flow meter in this system, can the accurate recording user use the gas situation, the data that relevant devices such as wireless data sending handheld reading meter device, wireless data sending concentrator, wireless data sending repeater, wireless data sending acquisition module, multi-functional hand-held data capture management device send in system when receiving control command, and this operation need not the meter reading personnel and registers one's residence, and avoids the contradiction of registering one's residence and producing.
2, solve financial pressure, accomplish to charge in advance, do not influence the accounting of transmission ﹠ distribution difference simultaneously again.
3, can carry out the setting of checking meter, closing valve and parameter to the user separately.
But what the mechanical reading of gas meter, flow meter was converted into the most employings of electron number is that step-by-step counting, photo-electronic directly reading or picture add wired or wireless transmission.
First kind of step-by-step counting mode is very high to the quality requirements of the size of magnet steel, installation site, tongue tube, and can not accomplish that the electron number and the machinery that obtain count up to entirely consequently, always have a difference (truth of a matter).
Second kind of photo-electronic directly reading mode.Employing at present all is light emitting diode and the combination of light receiver pope, it is bigger that this mode is influenced by light pollution, daylight disturbs, phase mutual interference during read data causes error code easily, so the photo-electronic directly reading counter appeared on the market existing several years, but because accuracy is low, poor reliability does not obtain promoting, the direct-reading gauge outfit of the employing camera mode that my company develops can effectively address the above problem, and improves reliability of products always.
Summary of the invention
The purpose of this utility model is exactly at the problem that presses for solution in the prior art, a kind of direct-reading gauge outfit is proposed, by this gauge outfit, play not relying on old stored counts mode and the directly effect of reading number, effectively eliminate the counting error of old system.
A kind of direct-reading gauge outfit comprises gauge outfit, camera, single-chip microcomputer, image processing module, display module and memory module; The lens location of described camera is corresponding with described gauge outfit; The video output terminals of camera connects the input end of image processing module; The output terminal of image processing module connects the input end of single-chip microcomputer; The output terminal of single-chip microcomputer connects the input end of display module; Single-chip microcomputer is connected with memory module.
Also comprise data transmission module, data transmission module and single-chip microcomputer carry out data communication.This data transmission module can be wire transmission module or wireless transport module.
Also comprise clock module, single-chip microcomputer output time data are given clock module.
Also comprise key-press module, the output terminal of key-press module connects the input end of single-chip microcomputer.
Described image processing module is to be the circuit of core with the OV7670 chip.
This gauge outfit employing camera mode is taken pictures to counter character wheel number and is discerned, and the result is transferred to single-chip microcomputer with data mode.
This direct-reading gauge outfit directly realizes the function that the numerical value of figure that camera is obtained extracts.No matter no matter no matter the color of gauge outfit character is the color on the border around colour or black and white, the character is no matter pattern around colour or black and white, the character is bar code or specific coding mode, can directly carry out numerical value and extract.
By single-chip microcomputer and image processing module obtaining image information is decoded, realize that decoded result is consistent with character wheel numerical value.
The realization of the technical program is:
