Abstract
Provided is a character wheel-type direct-reading gauge outfit. For the photoelectric direct-reading gauge outfit, at the light pulse emitting terminal, coded light pulses are transmitted in optical fibers. The coded light pulses are radiated onto a character wheel at specific positions, which are provided with reflective or light-permeable regions corresponding to characters on the character wheel. At the light pulse receiving terminal, coded light pulses from the reflective or light-permeable regions are received by optical fibers, and then are decoded by a decoding module, so that the corresponding characters of the character wheel are finally obtained. The optical fibers of the light pulse emitting terminal and the optical fibers of the light pulse receiving terminal are arranged in pair, and are located at corresponding positions. Corresponding to the ary of the character wheel, corresponding pairs of optical fibers of the light pulse emitting/receiving terminal are arranged, so that in each pair of optical fibers, emitted coded light pulses and received coded light pulses are consistent.

Description
Technical field
The utility model relates to a kind of character wheel formula meter sense method and character wheel formula direct-reading gauge outfit that adopts fiber optic conduction, 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, G PRS 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, and daylight disturbs, and the 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 always because accuracy is low, poor reliability does not obtain promoting.
