Description
Affiliated technical field
The utility model relates to a kind of angle detection device, especially a kind of high-resolution angular position detection device that can be applicable to meter kilsyth basalt index dials such as metering gas, liquid, electricity, pressure, temperature.
Background technology
Be generally used for measuring the meter kilsyth basalt of gas, liquid, electricity, pressure, humiture etc., its principle of work is to drive gearing by media such as gas, liquid, electricity by the pick-up unit in the instrument, driving the read text scale dish by gearing again rotates, when on the read text scale dish character code being set, the amount of spin of index dial is reflected by the character code that is arranged on the circumference, by the gearing certain gear ratio, by character code reflection give vent to anger, liquid, electricity, pressure, humiture equiscalar.At present, read the general method that manually directly reads that adopts of this character code.
Summary of the invention
In order to solve centralized management to meter kilsyth basalts such as water meter, gas meter, flow meter, ammeter, mechanical compression table, Hygrothermographs, the utility model provides a kind of high-resolution angular position detection device, can realize the remote monitoring to water meter, gas meter, flow meter, ammeter, tensimeter, Hygrothermograph etc.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of high-resolution angular position detection device, has the read text scale dish, every interval 36 degree are provided with 0～90 read text scale on the read text scale dish, and the read text scale dish links to each other with pick-up unit by gearing.Simultaneously also be provided with concentric detection dish corresponding to the read text scale dish, the read text scale dish is provided with marker, the detection dish is provided with the point detection signal of the unlike signal sign combination that is used to detect on the read text scale dish, externally is provided with the control assembly of the angular turn position signalling of received signal check point feedback read text scale dish.
On 180 ° of circumference of detection dish, be evenly distributed with 5 point detection signals, 36 ° of adjacent spaces, correspondence can adopt following eight kinds of method signalization signs on the disc of read text scale dish:
Method one: having central angle at the read text scale dish is 84 °, 12 °, 84 °, 84 °, 12 °, 84 ° six sector regions, regional signalization sign in every interval on sector region.See Fig. 2.
Method two: having central angle at the read text scale dish is 120 °, 12 °, 48 °, 120 °, 12 °, 48 ° six sector regions, regional signalization sign in every interval on sector region.See Fig. 3.
Method three: having central angle at the read text scale dish is 96 °, 60 °, 24 °, 96 °, 60 °, 24 ° six sector regions, regional signalization sign in every interval on sector region.See Fig. 4.
Method four: having central angle at the read text scale dish is 180 °, 84 °, 12 °, 84 ° four sector regions, regional signalization sign in every interval on sector region.See Fig. 5.
Method five: having central angle at the read text scale dish is 180 °, 48 °, 12 °, 120 ° four sector regions, regional signalization sign in every interval on sector region.See Fig. 6.
Method six: having central angle at the read text scale dish is 132 °, 48 °, 48 °, 132 ° four sector regions, regional signalization sign in every interval on sector region.See Fig. 7.
Method seven: having central angle at the read text scale dish is 120 °, 60 °, 60 °, 120 ° four sector regions, regional signalization sign in every interval on sector region.See Fig. 8.
Method eight: having central angle at the read text scale dish is 180 °, 60 °, 24 °, 96 ° four sector regions, regional signalization sign in every interval on sector region.See Fig. 9.
When these eight kinds of methods can guarantee that 0～90 read text scale revolution is crossed a scale, have only a signal to change in 5 check points, all the other are constant, can not occur intermediateness (two and plural variation) like this and can't discern.In addition, the part method can really reach revolution and cross 12 ° promptly during 1/3rd scale, has only a signal to change in 5 check points, and angular detection resolution improves 3 times, brings up to 12 ° by 36 °.Simultaneously, the part method has also well solved the resolution problem of angle non-uniform change.
It is great different that the utility model and all in the past similar technology have, and from the theory and practice aspect obvious difference arranged all:
First: point detection signal and marker be distributed with obvious difference.In the past be 5 point detection signals that on 360 ° circumference, evenly distribute, be separated by 72 °, and marker is to be that 36 ° sector region is that unit distributes according to different rules with central angle.So its every deflection just can change for 36 °, its angular detection resolution is up to 36 °.And the point detection signal in the utility model is to be evenly distributed on 180 ° the circumference, and marker is to be that 12 ° sector region is that unit distributes according to different rules with central angle, so its every deflection will change for 12 °, its angular detection resolution is 12 °, improves 3 times than in the past method angular resolution.Effect is obvious in actual applications for this, and is more with practical value.
Second: the utility model has solved " blind area " problem in the practical application effectively under the prerequisite of optimized Algorithm.In encryption algorithm in the past, have only two kinds of algorithms can solve " blind area " problem, a kind of is that half has marker on 360 ° the circumference, and half does not have, point detection signal can be uniform on the circumference of 360 ° or 180 °, but its angular detection resolution has only 36 °; Another kind is to be 54 °, 54 °, 126 °, 126 ° four sector regions with central angle, non-conterminous therein two sector regions are provided with marker, two sector region no signal signs in addition, point detection signal are evenly distributed on 360 ° the circumference, and its angular detection resolution is 18 °.In addition algorithm all can not solve " blind area " problem, and promptly between two scales, error code can appear in detection signal, causes actual scale position probing mistake maybe can't detect.All methods in of the present utility model all can solve " blind area " problem, and its angular detection resolution reaches 12 ° (methods three) simultaneously.
The 3rd: the utility model has solved " carry " problem in the practical application effectively.In encryption algorithm in the past, because its angular detection resolution is low, can't solve the synchronous carry problem of low level index dial and high-order index dial in the practical application, when this transient state, the physical location of high-order index dial and low level index dial can be not consistent, causes the input mistake.And angular detection resolution of the present utility model reaches 12 ° of i.e. 1/3rd scales, can determine the relative position of high-order index dial and low level index dial like this when carry, promptly can accurately judge its actual scale, mistake can not occur.
The 4th: the utility model can solve the detection problem of angle non-uniform change.Algorithm in the past all can not solve.Because the angular detection resolution of algorithms more of the present utility model is uneven distributions, can solve its angular detection problem at index dials non-homogeneous, non-360-degree such as some practical applications such as mechanical compression table, mechanical type Hygrothermographs like this.This is very valuable in actual applications.
More than 4 pointed out novelty of the present utility model and creativeness clearly, and different with similar technology in the past, and overcome drawback and defective in the similar in the past technology effectively have real practical application and promotional value.
The utility model goes for meter kilsyth basalts such as water meter, gas meter, flow meter, ammeter, dial type and pointer mechanical pressure gauge table, thermohygrometer, can realize the centralized management of the remote meter reading of such meter kilsyth basalt has been improved meter reading efficiency.
