About the selection of industrial control gateway IOT serial port to WiFi module and serial port to network port module

        With the development of Internet of things , The original physical layer of direct communication between the two machines through hardware to the data link layer of communication through hardware address and LAN has been far from meeting the needs of modern people's life and all walks of life production . Gradually combine high performance , High quality network layer and application layer . Realize intelligent terminal data collection , The data transfer , Data upload and wireless Internet ,WiFi Remote control and other functions . In the Internet of things market , From cost , Power waste , In terms of volume , Wireless Internet of things WiFi Module transmission is still through serial port WiFi Module based .

      A serial port WiFi Module is based on UART Interface embedded module , It conforms to WiFi Wireless network standards , Embedded in IEEE802.11 Protocol stack and TCP/IP Protocol stack , It can realize user serial port or TTL Conversion of level data to wireless network . Serial port type WiFi The working mode of the module is transmission type and command type .

      Now Xiaobian wants to talk about Multi thread and multi process routing serial port WiFi modular . With the real-time monitoring of field data , Remote control , Data upload , video transmission , The demand for audio transmission increases . Routing serial port WiFi Modules are gradually applied to all walks of life . The core CPU belt Linux System , It can process multiple threads and complex instructions at the same time ,. There are multiple serial UART Interface , When transmitting instructions, multiple instructions are issued at the same time , And respond quickly and deal with .

      With core CPU with Linux Routing serial port of system multithreaded processor WiFi modular RMS7688A modular Is compatible 802.11b/g/n Wireless AP Solution , Integrate 802.11n MAC/BB/PA/LAN, The bandwidth is relatively large , Can operate complex instructions at the same time .
