Description

Meter with direct reading function

The new model relates to a meter, especially a meter with a direct reading function.

Water, electricity, and natural gas are mainly connected to users' homes by pipes, and water meters, electricity meters, gas meters, etc. are installed to measure the use of electricity, water, and gas; and water, electricity, and gas At a fixed time, the company will send a specialist to the user's home to visually copy the usage of water, electricity or gas, and then issue a bill to charge the user.

However, manual meter reading operations often cause transcription errors due to human negligence, and for remote areas, it is time-consuming, labor-intensive and labor-intensive to go to the meter reading; in addition, although there are currently electronic meter parts, electronic There are many sensors and electronic components inside the meter. In addition to changing the design of the original meter, the inside of the meter is more complicated, which increases the cost of the meter. At the same time, the difficulty of maintenance is also increased, and the counting process is increased. In order to make the meter run smoothly, it must also keep the power on, and it also needs to consume additional power, which needs to be improved.

Therefore, the purpose of the new model is to provide a meter with a direct reading function, which directly reads the value of the display wheel of the meter, and can achieve the effects of simplified structure and energy saving.

Therefore, the new meter with direct reading function includes a body, a plurality of display wheels provided on the body and capable of displaying the measured flow value, and a display wheel provided on the body and capable of reading the display wheels A reader; wherein each digital area of the display word wheel is provided with a color layer having a different color from another digital area; further, the reader has a body disposed on the body and projecting light onto the A projection lamp on the digital area, a chromaticity sensor arranged opposite to the digital area and receiving reflected light, and a processor connected to the chromaticity sensor and judging the value of the displayed word wheel based on the chromaticity; When reading the value on the meter, the projection lamp is used to illuminate the digital area to generate a reflected light. After the reflected light is received by the photometric sensor, the processor will determine the meter based on the color of the reflected light. The value can be read stably and reliably, eliminating the problem of reading errors of the electronic counter, and simplifying the structure. It only needs to start the reader when it wants to read. It does not need to be powered on for a long time to count. It also saves energy. Effect.

The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiments with reference to the drawings.

Referring to FIG. 1 and FIG. 2, in the first preferred embodiment of the present invention, the meter 3 with direct reading function includes a body 31, a display wheel 32 provided on the body 31 and capable of displaying the measured flow value, and A reader 33 provided on the main body 31 and capable of reading the value of the display character wheel 32; wherein each display character wheel 32 has a plurality of number areas 321, and each number area 321 is provided on the surface There is a color layer 322 with a different color from the other digital area 321, that is, in this embodiment, the digital area 321 of each display word wheel 32 is a number 0-9, and each of the digital areas 321 is painted with The different color layers 322, at the same time, in order to improve the accuracy of the reading value, it can make the projection lamp 331 emit light sources with different chromaticities, and the chromaticity can be compared with each other to improve the accuracy of discrimination.

Still referring to FIG. 2 and FIG. 3, the reader 33 includes a projection lamp 331 provided on the main body 31 and capable of projecting the light onto the digital area 321, and a projection light 331 disposed opposite to the digital area 321 and A chromaticity sensor 332 for receiving reflected light, and a processor 333 connected to the chromaticity sensor 332 and determining the flow value according to chromaticity. In this embodiment, the processor 333 has a comparison unit 3331, And a storage unit 3332 storing values corresponding to the respective chromaticities. When the comparison unit 3331 receives the chromaticity sensor 332, the received chromaticity is compared with the chromaticity in the storage unit 3331 to determine the meter. Flow value of 3.

Referring to Figures 2, 3, and 4, in use, when the meter 3 performs flow detection, the display wheel 32 will rotate as the flow passes, and when it is desired to read the meter 3, it is activated by After the reader 33, the projection lamp 331 generates a projection light and projects it to the display character wheel 32, and after the projection light is irradiated to the digital area 321, it is irradiated to the color layer 322 and reflected out of the band There is reflected light of the color of the color layer 322. After receiving the reflected light, the chromaticity sensor 332 will identify the chromaticity of the reflected light and transmit it to the processor 333, and the processor 333 will After the chromaticity of the reflected light is compared, the received chromaticity of the reflected light is compared with the chromaticity stored in the storage unit 3332 through the comparison unit 3331, and it is determined which of the storage unit 3332 the chromaticity of the reflected light matches. After the chromaticity stored therein, the value of the chromaticity of the reflected light is compared, so that the value of the display word wheel 32 can be read out; therefore, relative to the reader 33 and the display word wheel 32 The digital layer 321 is provided with the color layer 322, and there is no need to provide a complicated layer inside the meter 3. The sub-components and counting structure do not need to be counted by electricity, which can effectively reduce the complexity and energy consumption of the meter 3 maintenance, and eliminate the problem of reading errors of the electronic counter. When you want to read, When the reader 33 is activated, it is not necessary to be powered on for a long time, and the effect of power saving can be achieved.

To sum up, the new meter with direct reading function has a color layer with different colors on the surface of the digital area of the word wheel of the meter, and the number is illuminated by the projection lamp of the reader. Area, a reflected light is generated, and after the reflected light is received by the chroma sensor of the reader, the processor of the reader judges the value of the display wheel according to the chromaticity of the reflected light, which will be stable The value can be reliably judged, eliminating the problem of reading errors of the electronic counter and achieving the effect of simplifying the structure. At the same time, the reader is started when the value is read. It does not need to be powered on for a long time, and it can achieve the effect of power saving.

However, the above is only to explain the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited by this, that is, the simple equivalent changes and modifications made according to the scope of the patent application of the new model and the content of the new specification, All should still fall within the scope of this new patent.
