WI-FI-based universal multi-protocol digital instrument internet-of-things module

Abstract

The invention relates to a WI-FI-based universal multi-protocol digital instrument internet-of-things module, which is designed from three aspects of WI-FI communication module hardware, an internet-of-things software protocol and an internet-of-things API function library, and provides a universal internet-of-things solution which is simple to transplant and adapt to different types of digital instruments and has powerful internet-of-things functions. The WI-FI communication module hardware adopts a wide voltage range serial interface design, and different Internet of Things transmission requirements are met by means of the high-speed transmission performance of WI-FI; the Internet-of-Things software protocol adopts a private instrument interaction protocol to interact with a digital instrument, adopts a private Internet-of-Things interaction protocol, an MODBUS-TCP protocol and a command transparent transmission protocol to interact with network equipment, and supports powerful Internet-of-Things functions such as instrument data timing forwarding/real-time high-speed forwarding, instrument working parameter debugging, MODBUS communication, instrument private command debugging and instrument firmware upgrading; the Internet-of-Things API function library provides highly packaged Internet-of-Things data variables and API functions compatible with different processor working modes through an IoT.lib file and an IoT.h file, and is used for simple and flexible adaptation of digital instrument Internet-of-Things functions; and therefore, a flexible and powerful Internet-of-Things function and a simple adaptation scheme are provided for different types of digital instruments.

Description

technical field [0001] The present invention relates to the Internet of Things technology of instruments and meters, especially a general-purpose IoT module based on WI-FI communication suitable for digital instruments to join the Internet, and supports the private Internet of Things interaction protocol and the standard MODBUS-TCP protocol at the same time. The development of the IoT function of the digital instrument provides a simple IoT API function library to realize the on-site communication or remote interaction between the digital instrument and other devices in the network through WI-FI, so as to provide communication, debugging, maintenance, cloud services, etc. for the digital instrument Powerful IoT functions. Background technique [0002] With the development of Internet of Things technology, there are more and more demands for combining network technology and instrument technology to realize the function of instrument IoT. There are usually two ways to realize...
