Traditional water meter

The calculation of the cost of traditional water meters requires a large amount of manpower for monthly meter reading. Especially in remote areas, maintenance is not easy, and hydraulic companies need to invest significant personnel costs. With the rise of IoT technology, the cost information of water meters is transmitted through the wireless network to reduce the cost of labor costs and become a new manifestation. However, the comprehensive replacement of the water meter takes time and costs, not to mention the cost, so alternative solutions are born.

Wireless camera module plus image recognition technology

The existing traditional water meter is equipped with a CMOS camera ( with a wireless transmission module ), and the cost of the water meter is photographed regularly. After the number is recognized by the image recognition technology, the wireless module is used to transmit the information.

NuMicro M480 Development Platform

Nuvoton Technology provides the NuMicro M480 series development platform based on Cortex-M4 core, which uses GPIO to emulate CMOS interface to receive images ( image resolution 320 x 240 ), and quickly complete image recognition operation through core speed up to 192 MHz and DSP hardware accelerator. The numbers are transmitted using wireless transparent transmission modules ( such as Wifi, 2G / 4G, NB-IoT and other wireless transmission protocols ).
