Description

A kind of comparison expression direct-reading gauge table
Technical field
The present invention relates to the sensors of gauge table.
Background technique
There are following scarce limits, mainly light for a kind of non-contact direct reading type gauging table (number of patent application 2005200547306) For electric device with using the time long, parameter change causes reading to malfunction.Occurs meter reading error after many half a year.Direct-reading intelligence The gauge tables such as ammeter, intellectual water meter and intelligent gasometer determine pointer or the character wheel turned position of gauge table with electronic component.Such as 0 to 90 numbers on character wheel are indicated with ten different gray scales.It is most black to indicate 9, most white expression 0.When 9 are transitioned into 0, photosensitive tube Incude most black and most white average value, it is possible to the influence value as 5 occur.The intellectual water meter now used, needle pivot and water Rachis is connected with magnet.There is a plastic plate among two axis, by electronic section and water segregation.The circle number for be easy to causeing waterleaf to rotate Greater than needle pivot, cause intellectual water meter metering inaccurate.The pointer or word of pulse intelligent ammeter, intellectual water meter and intelligent gasometer One circle of wheel rotation, add up a pulse.Pointer or the character wheel turned position for only judge lowest order (such as an a position), do not judge ten, Hundred, the high-order pointer or character wheel turned position such as kilobit.Ten, hundred, the data of kilobit lean on the pulse data of a position cumulative. Such as without electricity, cumulative pulse data can be lost.It to be powered for a long time, the pointer of (a position) or character wheel turnning circle be not when out of power It can be cumulative.The umber of pulse of loss out of power cannot be restored after powered up.
Summary of the invention
The purpose of the present invention is provide a kind of comparison expression direct-reading gauge table.
The technical solution adopted by the present invention 1 be include a luminous tube and multiple photosensitive tubes, the number of photosensitive tube is equal to number Digital number on letter stencil, photosensitive tube are uniformly distributed centered on axis along surrounding.Technical solution 2 be a photosensitive tube with it is multiple The number of luminous tube, luminous tube is equal to number digital on digiboard, and luminous tube is uniformly distributed centered on axis along surrounding.
Further, the technical solution 1 or technical solution 2 are photosensitive tube opposites equipped with luminous tube, and digiboard is fixed Motionless, pointer one end connecting shaft, pointer rotates on digiboard using axis as the center of circle.
Further, the technical solution is pointer equipped with luminous tube or photosensitive tube.
Further, the technical solution is pointer in the centre of photosensitive tube and luminous tube.
Further, the technical solution 1 or technical solution 2 are photosensitive tube and luminous tube towards pointer, and digiboard is solid Fixed motionless, pointer one end connecting shaft, pointer rotates on digiboard using axis as the center of circle.
Further, the technical solution 1 or technical solution 2 are to be photosensitive tube opposite equipped with luminous tube, digiboard On axis, digiboard is rotated by the center of circle of axis.
Further, the technical solution is digiboard equipped with luminous tube or photosensitive tube.
Further, the technical solution is digiboard in the centre of luminous tube and photosensitive tube, and digiboard has hole.
Further, the technical solution 1 or technical solution 2 are photosensitive tube and luminous tube towards digiboard, digiboard Color lump is connected, digiboard is rotated by the center of circle of axis.
The beneficial effects of the invention are as follows the comparisons of ten parameters of the parameter or a photosensitive tube that pass through ten photosensitive tubes, really Determine pointer or character wheel turned position.The present invention can eliminate character wheel or pointer and be transitioned into 0 error 9.The present invention can be used for Wet-type meter, all electronic components are not soaked, can increase the life in application of electronic component.The rotation axis of water meter is directly connected to waterleaf Axis, be not in waterleaf rotation circle number be greater than needle pivot, improve the accuracy of intellectual water meter.The present invention can be used in intelligent coal Gas meter, electronic section are separated with coal gas, be can avoid electronic component electric discharge and are caused fire.The present invention can be used in intelligent electric meter, intelligence It can the gauge tables such as water meter and intelligent gasometer.It is just powered when reading the data of gauge table, energy consumption is small.Existing pulse intelligent electricity Table, intellectual water meter and intelligent gasometer will be electrified for a long time, and energy consumption is high.Power consumption of the invention be less than 100 milliwatts, the time 0.5 second.Often It is powered when moon meter reading primary, 5 amp-hour batteries can be used 15 years.Year is used more than intelligent electric meter, intellectual water meter and intelligent gasometer Limit.
