The block diagram shows a unidirectional AMIGO board. This board is differentiated from the development board by being designed to be closer to the product. The main components include a main MCU with an RTOS and a metering chip responsible for power metering. The main MCU area contains CAN, RS-485, Wi-SUN communication modules, KCMVP security chip, EEPROM, and connections to the LCD.
The metering chip part is responsible for processing the power measurement data input from the CT through analog front-end logic and passing it to the main MCU. With this configuration, the board provides the product with a harmonious function and form, and realizes efficient data processing and communication in various areas.

The internal system block diagram of a smart gas meter consists of the following main components. The main MCU, which is the main axis, coordinates the various functions and drives data processing and communication. Precise gas metering is achieved through the gas metering module, while the communication module utilizes wireless technology to transmit usage data. To ensure user data security, the security module plays an important role. Power management and backup batteries support continuous operation, while displays and UI help provide convenient information to users. Including modules for data storage and time management, and sensors and detectors, smart gas meters play a key role in energy management through efficient and accurate data collection.
Multi-Jet Water meter.jpg)
The internal system block diagram of a multi-jet water meter has the following main organization. The main MCU drives the data processing, communication, and metering tasks, while the multi-jet metering module is responsible for accurate water flow metering. The data communication module transmits water usage and meter status data externally. Power management and backup batteries ensure continuous operation of the meter, while the display and UI visually communicate information to the user. Finally, the flow detection sensor performs accurate water flow detection. Together, these elements enable the multi-jet water meter to collect accurate data, provide valuable information, and efficiently manage water usage.
