Things Component Architecture
Processor: all peripheral devices are to be connected to the IO processor, data acquisition, issued instructions, data transmission and other functions controlled by the processor.
Memory: microcontroller as the core of the terminal device, the memory is not necessary, because the microcontroller itself comprises a set of operator, RAM, ROM's. Required in the case of ROM can not meet the stored external memory, the need to run linux terminal memory is required, the type of memory has a NAND Flash, NOR Flash, EEPROM, SD card, TF card, the specific needs determined by the projects.
Sensor: converting external information into the computer signal converter.
Actuator: a control circuit, a mechanical device, such as relays, motors. Computer to control a real object by controlling the actuator.
Multimedia: In addition to numbers, sounds, pictures, videos, these information collection required to support multimedia devices, such as sound cards, camera.
Communications chips: Things to upload data, receive data needs to communicate with the background.
OS: Low power consumption of the terminal device, the unique things traditional pc network communication can not satisfy the needs of a particular development.
Human-computer interaction: screen display, keyboard input, voice input, touch screen.
Network Infrastructure: dispersing device things, the complexity of the application scenario requires a variety of network types, need to support many different applications things device from power, delay, bandwidth, network capacity, coverage and stability Scenes.
WiFi, wired network: coverage rate is fast, but not wide. Mobile network: Coverage has been raised but in the ground, can not cover remote. ZigBee, Bluetooth mesh, networking: communication distance and power consumption is not optimal. Lora, NB-IoT low-power low power consumption to meet a wide area network, the communication distance is long, but the communication rate is low, can not meet the large data transfers.
