The setting position of wherein said photo-electric conversion element A5 and photo-electric conversion element B8 centered by water meter runner 7, in asymmetric setting.Described photo-electric conversion element A5 and photo-electric conversion element B8 is bonded on the glass of mechanical water meter 1.The viewing window of described mechanical water meter 1 is provided with housing 6, and the bottom land of described housing 6 is provided with pcb board erection column.
The present invention is when real work, when needing the accumulated water volume data of collection machinery water meter 1, the data that camera shooting water meter lettered dial 2 in shooting direct-reading recognition unit 3 shows, data are stored in the single-chip microcomputer in shooting direct-reading recognition unit 3 with the form of picture, then the picture of single-chip microcomputer to shooting in shooting direct-reading recognition unit 3 does binaryzation, denoising, identify, finally obtain the accumulated water volume data of water meter lettered dial 2, data send out by the communication chip in shooting direct-reading recognition unit 3, power supply chip in shooting direct-reading recognition unit 3 is responsible for the operating voltage of external Power convert needed for imaging identification cell operation.In the present invention, square wave counting unit comprises photo-electric conversion element A5 and photo-electric conversion element B8, photo-electric conversion element A5 and photo-electric conversion element B8 glue are fixed on water gage glass, near the place of water meter runner 7, the position that photo-electric conversion element A5 and photo-electric conversion element B8 arranges is centered by water meter runner 7, in mal-distribution, photo-electric conversion element A5 is connected with shooting direct-reading recognition unit 3 by electric wire with photo-electric conversion element B8, when water meter runner 7 rotates, photo-electric conversion element A5 and photo-electric conversion element B8 exports with the square-wave signal of two row some cycles.
When real work, when needs collection machinery water meter 1 instantaneous delivery, the input of one in photo-electric conversion element A5 and photo-electric conversion element B8 turned off by single-chip microcomputer, only gather the output signal of a photo-electric conversion element, obtain the square-wave signal that row are period profile, single-chip microcomputer process obtains the cycle of square-wave signal, namely may correspond to the instantaneous delivery obtaining mechanical water meter 1.Such as, when the instantaneous delivery in water pipe is 0.01 cube of meter per second, suppose that the corresponding rotating speed of water meter runner is 50 revolutions per seconds, the output signal of corresponding photo-electric conversion element to be the cycle the be row square-wave signal of 0.02 second, single-chip microcomputer collects the output signal of photo-electric conversion element, the cycle obtaining output waveform is after treatment 0.02 second, can determine that the instantaneous delivery in water pipe is 0.01 cube of meter per second.
When real work, when whether there is refluence in needs detection water pipe, single-chip microcomputer gathers the output signal of light photo-electric conversion element A5 and photo-electric conversion element B8 simultaneously, obtains two row square-wave signals, single-chip microcomputer judges the sequencing of two row square-wave signals, can judge whether there is refluence in water pipe.
When real work, when needs do leak water detdction, first a time cycle is set, if single-chip microcomputer does not detect the square-wave signal that photo-electric conversion element A5 and photo-electric conversion element B8 exports within the time cycle of setting, then be judged to not leak, if the square-wave output signal of photo-electric conversion element detected within the time cycle of setting, be then judged to be that existence is leaked.
To make a video recording in the present invention the identification of direct-reading recognition unit 3 for the water meter registration of water meter lettered dial 2 on mechanical water meter 1, square wave counting unit is used for instantaneous delivery, the realization of the flow backwards functions such as detection, leak water detdction, wherein photo-electric conversion element A5 and photo-electric conversion element B8 is optoelectronic multiplex switch, the present invention realizes refluence measuring ability, and the position of two photo-electric conversion elements must be arranged with asymmetric manner.
The present invention is when real work, when communication chip receives flow data collector instruction, after single-chip microcomputer process, pass through photo-electric conversion element, the runner of water meter is converted to the square-wave signal with some cycles, send single-chip microcomputer process to, then obtain data on flows, then through communication chip, data are sent.Optoelectronic multiplex switch timing detects the sense of rotation of water meter runner, utilize the photo-electric conversion element of two asymmetric arrangement, the runner of water meter is converted to two row square-wave signals, send single-chip microcomputer process to, judge that the sequencing of two row square waves can obtain water meter runner rotating information, if there is reversion, then judge to occur flowing backwards in pipeline, then through communication chip, refluence information is initiatively sent.
During leak water detdction, first a time cycle is set, if when within the time cycle set, photo-electric conversion element detects the rotation of water meter runner, the output level of photo-electric conversion element changes, when microprocessor detect changes to the output level of photo-electric conversion element, can determine that pipeline exists to leak, then initiatively send through communication chip information of leaking.
Not electricity consumption when intelligent telemetering water meter of the present invention has standby at ordinary times, the water meter truth of a matter need not be set, overcome the shortcoming that shooting direct-reading water meter can not read instantaneous delivery data, also overcome square wave water meter need arrange the water meter truth of a matter, fail to record the inaccurate problem of the water consumption metering that causes because of square wave, achieve the multiple functions such as accumulated water volume, instantaneous delivery, refluence detection, leak water detdction simultaneously.
Part not in the detailed description of the invention is prior art.
