Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a water meter character wheel device for direct camera reading. Background Art

[0002] The camera-based direct-reading water meter is a water meter that has a camera component installed above it. The code characters on the water meter wheel are read by camera, and the images captured by the camera are then transmitted to the processor and cloud platform to enable manual remote meter reading.

[0003] Water meters are generally installed in relatively dim places. Installing a camera assembly above the water meter makes it even darker. At the same time, the surface of the character wheel is relatively smooth, which makes it easy to reflect light. This reduces the clarity and color contrast of the code words on the picture obtained by the camera assembly, increases the complexity of parsing the water meter code word picture, and even causes picture parsing errors, affecting the accuracy of remote meter reading data. Utility Model Content

[0004] The utility model aims to provide a water meter character wheel device for direct camera reading, so as to solve the technical problem proposed in the above background technology that in a dim environment, when the camera assembly reads the code characters on the water meter character wheel by camera, the surface of the character wheel is relatively smooth and thus easy to reflect light, resulting in reduced clarity and color contrast of the acquired image, making it difficult to analyze the image or even erroneous to analyze the image, thereby affecting the accuracy of remote meter reading data.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a preferred solution, the inner walls on both sides of the character wheel box are provided with the slide grooves, the slide rails are provided in the slide grooves, the slide rails are slidably connected with slide blocks, and the slide blocks are provided with drive motors.

[0009] As a preferred solution, both ends of the mounting rod are respectively mounted on the sliding block.

[0010] As a preferred solution, a rotating shaft is provided at the center of the character wheel, and the character wheel is rotatably connected to the mounting rod via the rotating shaft.

[0011] As a preferred solution, a plurality of transmission teeth are provided on both sides of the character wheel, and the plurality of transmission teeth are distributed on both sides of the character wheel in a circular array.

[0012] It can be seen from the technical solution provided by the utility model that the utility model provides a water meter character wheel device for direct camera reading, which has the following beneficial effects:

[0013] 1. When camera reading is required, the character wheel moves up along the slide groove along with the mounting rod, and the upper part of the character wheel can move out of the character wheel box as the character wheel moves up, so that the distance between the code words on the character wheel and the camera assembly becomes closer, and the character wheel protrudes out of the character wheel box, and the code words are convex in the code word groove, which is conducive to the camera assembly focusing on the code words on the character wheel, and improves the clarity and contrast of the code words on the character wheel in the picture;

[0027] See also Figures 1 to 6 The embodiment of the present application provides a water meter character wheel device for direct camera reading, comprising a character wheel box 1, a mounting rod 2, a slide groove 3, a character wheel 4, a code word groove 41 and a code word 42. The character wheel box 1 is provided with a mounting rod 2, a slide groove 3 is provided on the side wall of the character wheel box 1, the mounting rod 2 is slidably connected to the slide groove 3, a limit block 33 is provided on the upper end of the slide groove 3, the mounting rod 2 is rotatably connected to the character wheel 4, the wheel rim of the character wheel 4 is provided with a code word groove 41, and ten code words 42 are sequentially provided in the code word groove 41, and the ten code words 42 are convex.

[0028] Furthermore, four character wheels 4 are provided, and ten code words 42 are provided on each of the four character wheels 4, and the numbers of the ten code words 42 are 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 in sequence.

[0029] Furthermore, in order to make the image read by the camera clearer and avoid reflection caused by the background being too white, the codeword groove 41 is set to black and the codeword 42 is set to be white and raised.

[0030] Working principle and effect: the mounting rod 2 can move up and down along the slide groove 3, and the character wheel 4 is mounted on the mounting rod 2, so that the character wheel 4 can move up and down in the character wheel box 1. Under normal use, the mounting rod 2 is located at the bottom of the slide groove 3, and the character wheel 4 is located in the character wheel box 1; when camera reading is required, the character wheel 4 moves up along the slide groove 3 along with the mounting rod 2, and the limit block 33 limits the upward movement of the mounting rod 2 to prevent the mounting rod 2 from slipping out of the slide groove 3 upward, and the character wheel 4 moves up so that the upper part of the character wheel 4 can move to the outside of the character wheel box 1, so that the distance between the code word 42 on the character wheel 4 and the camera assembly becomes closer, and the character wheel 4 protrudes outside the character wheel box 1, and the code word 42 is convex in the code word groove 41, which is conducive to the camera assembly focusing on the code word 42 on the character wheel 4, and improves the clarity and contrast of the code word 42 on the character wheel 4 in the picture.

[0031] In one embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the inner walls on both sides of the character wheel box 1 are provided with a slide groove 3, a slide rail 31 is provided in the slide groove 3, a sliding block 32 is slidably connected in the slide rail 31, and a driving motor is provided on the sliding block 32. The slide groove 3 is provided on the inner walls on both sides of the character wheel box 1, and the slide rail 31 is provided in the slide groove 3. The sliding block 32 is installed in the slide rail 31, which effectively prevents the sliding block 32 from falling off the slide rail 31 during the sliding process, and the sliding block 32 is driven by the driving motor to move up and down along the slide rail 31.

[0032] In one embodiment, Figures 2 to 3 As shown, the two ends of the mounting rod 2 are respectively mounted on the sliding blocks 32. The sliding blocks 32 slide up and down to drive the mounting rod 2 to move up and down, thereby driving the character wheel 4 to move up and down.

[0033] In one embodiment, Figure 6 As shown, a rotating shaft 43 is provided at the center of the character wheel 4, and the character wheel 4 is rotatably connected to the mounting rod 2 via the rotating shaft 43. The character wheel 4 is rotated on the mounting rod 2 via the rotating shaft 43, so that the mounting rod 2 only needs to provide support for the character wheel 4 and can drive the character wheel 4 to move up and down, avoiding the need for the mounting rod 2 to drive the character wheel 4 to rotate and move up and down at the same time, which affects the stability of the mounting rod 2.

[0034] In one embodiment, Figure 6As shown, a plurality of transmission teeth 44 are provided on both sides of the character wheel 4, and the plurality of transmission teeth 44 are distributed in a circumferential array on both sides of the character wheel 4. A plurality of transmission teeth 44 are respectively provided on both sides of each character wheel 4, which are distributed in a circumferential array around the center of the circle.
