The automatic remote water meter reading device can be directly installed on the old mechanical water meter 10 without any modification to the old mechanical water meter 10 .

The two semi-circular snap rings 1 are symmetrically arranged and encircled to form a ring, which is clamped on the dial of the old mechanical water meter 10 , and two ends of the two semi-circular snap rings 1 can be detachably connected by bolts. There are a plurality of mounting holes for connecting the pillars 2 around the semicircular open ring 1. The lower ends of the pillars 2 are inserted into the mounting holes, connected by connecting parts such as nuts, and the upper ends are connected to the PCB boards (Printed c i rcu i t boards, printed). circuit board) 3, it can also be fixed by nut connection. The PCB board 3 is used to carry various components and provide circuit connections.

The camera 4, the lighting lamp 5, the microcontroller 6, the network sending unit 7 and the power supply 8 are respectively arranged on the PCB board 3, and the camera 4 and the lighting lamp 5 are arranged towards the dial of the old mechanical water meter 10, and the length of the control pillar 2 is equal to the focal length of the camera 4. , so that the camera 4 focuses on the dial of the old mechanical water meter 10. The lighting lamp 5 functions as a flash, and supplements the illumination when the camera 4 is shooting. The single chip 6 is respectively connected to the camera 4, the lighting lamp 5 and the network sending unit 7, and controls their work. The MCU 6 is installed with relevant software to control the camera 4 to take pictures. When the camera 4 takes pictures, the lighting lamp 5 is used as a flash for supplementary light, and then the numbers on the pictures are recognized and sent to the data center of the water supply unit through the network sending unit 7. The above structures and control methods are all existing technologies, and are widely used in smart phones (smart phones have matured to use cameras, flashes and network transmission units for many years, and it is also a mature technology to recognize characters and numbers in photos), so related Those skilled in the art are fully aware of this, and will not be repeated here.
