Description
Technical Field
The invention belongs to the technical field of metering equipment, and particularly relates to an angle position coding structure of a metering instrument, a data acquisition device, the metering instrument and a method.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
In the process of data acquisition of metering instruments such as water meters, data are read by adopting a mode of coding a digital zone. In the prior art, a reflective meter provided by the patent document with publication number CN106679699a and a photoelectric direct-reading combined character wheel and a coding structure on the character wheel provided by the patent document with publication number CN113124942a are both coding modes of combining a blank area and a shadow area, but the modes may influence the accuracy of data acquisition due to shadows generated by stains on an instrument panel. In addition, although dirt can be prevented from entering the surface of the water meter glass and the contact part of the sensor through a sealing ring and the like so as not to block light transmission, most of the other surfaces of the water meter glass cannot be shielded so as not to influence meter calibration and manual reading, thus, ambient light can irradiate a reflecting disc through the glass, reflected signals can be collected, the intensity of the reflected signals can even exceed the influence of a luminous tube, and sensing errors can be caused.
The current metering instrument data acquisition device can be independent of a base meter and is detachable, and has the advantages of convenience in maintenance and the like. However, the current detachable data acquisition device mainly adopts a Hall or magnetic resistance as a sensor, and a magnetic induction structure of a magnet is arranged on a rotary pointer of the water meter, but the device is easily interfered by an external magnet and gradually replaced by a structure without a magnetic sensor. The structure without magnetic sensor is a structure with inductance coil as sensor and semi-circular stainless steel metal disc installed on the pointer of water meter for metal detection. But the technology is still based on the electromagnetic induction principle and is interfered by external dynamic electromagnetic fields. Particularly, in the application of the novel Internet of things water meter which uses wireless transmission technologies such as NB-IOT and the like as transmission modes, the data transmission is easy to cause the loss of pulses or the counting of a plurality of pulses.
In summary, the following problems still exist in the data acquisition field of the current metering device:
(1) Most of the existing coding modes adopt a coding mode of combining a blank area and a shadow area, but the mode can influence the accuracy of data acquisition due to shadow generated by stains on an instrument panel and even reflection of ambient light.
(2) The current metering instrument data acquisition device is easy to be interfered by external dynamic electromagnetic fields based on an electromagnetic induction principle, so that the wireless data transmission is easy to cause the loss of pulses or multiple meters, and the accuracy of the metering instrument data acquisition is affected.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the present invention. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.
Example 1
The embodiment provides a data acquisition device of metering device, it includes:
the metering device comprises a metering device angular position coding structure, a color sensing element 4 and a signal processing module;
wherein the metering instrument angular position coding structure comprises a coding region; the coding region comprises ten digital coding regions; each digital coding region is composed of three sub coding regions, and each sub coding region is any one of a red region, a green region and a blue region; the color combinations in the digital coding region are in one-to-one correspondence with dial numbers 0-9 of the metering instrument;
the color sensing element 4 is used for collecting color combination signals corresponding to the current indication number of the metering instrument and transmitting the color combination signals to the signal processing module;
the signal processing module is used for decoding the current indication according to a one-to-one corresponding coding relation between the predetermined color combination signal and the digital codes.
The reason why the digital coding region in this embodiment uses three colors of red, green and blue for coding is: the red, green and blue are three primary colors, and the three primary colors of red, green and blue are mutually independent, and other colors can be mixed by the three primary colors of red, green and blue according to different proportions. Therefore, on the premise of the minimum primary colors, the measurement error can be reduced, and the measurement accuracy can be improved.
As a preferable scheme, only one color of two adjacent digital coding regions in the digital coding regions corresponding to the numbers 0-9 is changed, and the colors of the other two sub coding regions are unchanged. Therefore, signal errors caused by color jump can be avoided, and the accuracy of data acquisition of the metering instrument is improved.
Taking the disc type instrument panel of fig. 1 as an example, coding from outside to inside of the disc;
the code of the number 0 is GRB;
the code of the number 1 is GRR;
the code of the number 2 is GBR;
the code of the number 3 is BBR;
the code of the number 4 is BBG;
the code of the number 5 is BRG;
the code of number 6 is RRG;
the code of the number 7 is RBG;
the number 8 is encoded as RBB;
the code of number 9 is GBB.
In fig. 1, G represents green, R represents red, and B represents blue.
It will be appreciated that in other embodiments, the numbers 0-9 may be any one, two or three of red, green and blue regions, so as to form a three-character code, which will not be described in detail herein.
In one or more embodiments, to reduce the effect of color differences of different colors on decoding, each digitally encoded region is the same size.
The three sub-coding regions of each digital coding region are a first sub-coding region, a second sub-coding region and a third sub-coding region respectively;
all the first sub-coding regions have the same size;
all second sub-coding regions are the same size;
all third subcode regions are the same size.
In one or more embodiments, the coding region bisects the dial of the meter.
For example, in fig. 1, when the digital dial of the metering device is a disc, the coding regions are in the shape of discs, and the ten digital coding regions equally divide the discs.
In fig. 2, when the digital dial of the metering device is an integer digital wheel, the coding regions are in a circular ring shape, and the ten digital coding regions equally divide the circular rings.
According to the embodiment, different codes can be identified according to the relative intensity relation between red, green and blue receiving signals by reflecting light rays with different colors by the red, green and blue reflecting coding surfaces, and the problem of signal acquisition errors caused by the interference of ambient light of single-color photoelectric sampling is solved by three-color photoelectric.
In one or more embodiments, the color sensing element may be implemented using three single color receiving tubes or one tri-color receiving tube.
Specifically, the color sensing element detects the color by comparing the object color with the reference color that has been previously taught, and outputs the detection result when the two colors agree within a certain error range. The color sensing element can be implemented by adopting the existing structure, and a person skilled in the art can specifically select a specific model of the color sensing element according to the actual precision requirement.
It should be noted that the signal processing module may be implemented by a signal processor, and the specific model thereof may be specifically selected by those skilled in the art according to practical situations.
In some other alternative embodiments, a one-to-one coding relation table of the color combination signals and the digital codes is pre-stored in the signal processing module, and when the color combination signals corresponding to the current readings are obtained, the current readings of the metering instrument can be obtained according to the query coding relation table.
Taking fig. 3 as an example, the metering device comprises a disc type digital dial 2 and an integer digital dial 1. Wherein, for the integer digital wheel digital dial, the cambered surface emission application layout structure shown in fig. 4 can be adopted.
In one or more embodiments, the data acquisition device further comprises a light supplementing element 3, the light supplementing element 3 is arranged on the metering instrument panel, and the light supplementing element 3 is used for emitting white light to serve as a light supplementing light source.
Here, the light supplementing element 3 may be implemented by using full-color LEDs.
When external environment light exists, the light supplementing element 3 can not emit light, and the red, green and blue reflection coding surfaces also reflect light rays with different colors and do not influence the relative intensity relation of the received red, green and blue signals.
In some embodiments, when the metering device includes a pointer, the pointer is provided with a reflective element, and the color sensing element is used for collecting reflected light of the reflective element and transmitting the reflected light to the signal processing module, and the signal processing module detects rotation of the pointer.
It should be noted that the light reflecting element may be a light reflecting disc or other light reflecting object.
The structure of the optical disc is an existing structure, and a person skilled in the art can specifically select a model according to actual situations, which will not be described here.
In other embodiments, when the metering device includes a pointer, the pointer may also be coated with a reflective material, and the color sensing element is configured to collect reflected light of the reflective material and transmit the collected reflected light to the signal processing module, where the signal processing module detects rotation of the pointer.
In actual production, the reading mode of the data acquisition device of the metering instrument can adopt the following modes:
mode one: read-only integer digits;
mode two: read-only decimal places;
mode three: all bits are read.
In the reading mode of mode one, the meter angular position coding structure described in the above embodiment one may be provided only in the position area of the whole digits of the dial plate of the meter.
