A universal multi-protocol digital instrument IoT module based on wi-fi

Abstract

The present invention is a general-purpose multi-protocol digital instrument IOT module based on WI‑FI, which is designed from three aspects: WI‑FI communication module hardware, IOT software protocol and IOT API function library, and provides different types of digital instruments. A general-purpose IoT solution with simple porting and adaptation of instruments and powerful IoT functions. The hardware of the WI‑FI communication module adopts a wide voltage range serial interface design, with the help of WI‑FI’s high-speed transmission performance to meet different IoT transmission requirements; the IoT software protocol uses a private instrument interaction protocol to interact with digital instruments, and uses a private IoT interaction protocol, MODBUS-TCP protocol and command transparent transmission protocol to interact with network devices, support instrument data timing forwarding / real-time high-speed forwarding, instrument working parameter debugging, MODBUS communication, instrument private command debugging, instrument firmware upgrade and other powerful IoT functions; The IoT API function library provides highly encapsulated IoT data variables and API functions that are compatible with different processor working modes through the IoT. Different types of digital instruments provide flexible and powerful IoT functions and simple adaptation solutions.

Description

technical field [0001] The invention relates to the Internet of Things technology of instruments and meters, in particular to a general-purpose Internet of Things module based on WI-FI communication suitable for digital meters 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 digital instruments provides a simple IOT API function library to realize on-site communication or remote interaction between digital instruments and other devices in the network through WI-FI, thereby providing communication, debugging, maintenance, and cloud services for digital instruments. Powerful IoT functions. Background technique [0002] With the development of IoT technology, there are more and more demands to combine network technology with instrument technology to realize the IoT function of instrument. There are usually two ways to realize the IoT function of t...
