Master-slave wireless transmission module used for air electric gauges

Abstract

The invention relates to a master-slave wireless transmission module used for air electric gauges. The master-slave wireless transmission module is characterized by comprising a master module connected with an upper computer and slave modules installed on the air electric gauges, and the multiple slave modules are wirelessly connected with the master module. Each slave module comprises an AD conversion chip, a slave module single chip microcomputer, a slave module wireless transmission chip and a slave module antenna, wherein the output end of the AD conversion chip is connected with the input end of the slave module single chip microcomputer, the slave module single chip microcomputer is connected with the slave module wireless transmission chip, and the slave module wireless transmission chip is connected with the slave module antenna. The master module comprises a USB to serial port chip, a master module wireless transmission chip, a master module single chip microcomputer and a master module antenna, wherein the master module antenna is connected with the master module wireless transmission chip, a master module wireless sensing chip is connected with the master module single chip microcomputer, and the master module single chip microcomputer is connected with the USB to serial port chip. The requirement for wireless data transmission between multiple air electric digital gauges and the upper computer is met.

Description

technical field [0001] The invention relates to a master-slave wireless transmission module for a gas electricity meter, especially a wireless transmission module for uploading measurement data of a gas electricity meter to a host computer, which belongs to wireless transmission and IoT perception technology field. Background technique [0002] With the rapid development of modern industrial automation technology, the demand for wireless data communication is becoming more and more intense. For industrial sites, wireless transmission needs to have high reliability and real-time performance. Smart factories put forward real-time and intelligent requirements for production management. After the original gas-electric digital display measuring instrument detects the size of the workpiece, it transmits the measured data to the host computer through the communication serial port with a wired connection. . When multiple gas-electric digital display meters work at the same time, w...

AI Technical Summary

Problems solved by technology

When multiple gas-electric digital display meters work at the same time, wiring between each measuring instrument and the host computer is required, and the wiring cost is very high, and there are high requirements for time, installation and commissioning costs , so the wired method of measurement and quality inspection is becoming more and more difficult to meet the needs of the growing smart factory Internet of Things

However, the existing wireless modules such as ZigBee and WiFi have some problems in the direct application of quality inspection in the production line.
