Description
[technical field]
The utility model relates to and a kind ofly reads the device of counter values by optical mode, is mainly used in flowmeter (water meter, ammeter, gas meter etc.) is carried out remote reading.
[background technology]
Existing flowmeter remote reader system generally relies on the method for long-range pulse output to carry out the collection and the measurement of data, promptly impulse sender is set at the flowmeter place, when meter readings changed, impulse sender sent pulse signal to statistical unit and realizes data acquisition.But said system is former thereby bursts of error occurs, lose pulse or multipulse phenomenon because of the interference of surrounding enviroment signal, power fail or official website backflow etc. easily, causes the original reading of long-range data that obtain and flowmeter to have deviation, and it is unreliable to work.
And the impulse sender end must install battery, and battery is limited serviceable life, and the replacing of battery is cumbersome, uses inconvenience.
In order to address the above problem, the device of remote collection flow meter data has also appearred coming with the optics metering system, promptly the both sides of each counting scale of flowmeter be provided with respectively with wiring board on the light conveyer that links to each other with receiving tube of luminotron, and offer some resistance light sections and logical light section in axle center, counting scale upper edge, during measurement, give the energising of luminotron and receiving tube, make the light conveyer of a side send some Shu Guang, and the light conveyer that a few bundles of these some Shu Guangzhong can't arrive opposite side owing to be subjected to hindering stopping of light section, just can judge which light according to the signal that receiving tube obtains then has been subjected to stopping, which light has then passed through logical light section, thereby obtain the state of counting scale by the position of resistance light section and logical light section, just realized remote reading.
