AUTOMATED ENVIRONMENTAL MONITORING DATA COLLECTION, RECORDING, AND TRANSMISSION EQUIPMENT

Abstract

The invention relates to an automatic environmental monitoring data acquisition, recording, and transmission device, comprising a central controller with a 32-bit microcontroller, a sensor communication unit, a data processing unit, a local storage unit, a communication unit, a Web interface, and control outputs. The sensor communication unit receives data from various sensors via current signals from 4 mA to 20 mA, voltage signals, digital inputs, pulse inputs, and Modbus protocol. The controller processes the data, determines the state of the measuring device, assigns a timestamp, and stores the data on a memory card. According to a set cycle, the data is packaged into a file and transmitted to the server via a 4G / GSM and / or Ethernet network. The device checks the server's response and automatically retransmits unconfirmed data. When valid measurement data exceeds a predetermined threshold, the device issues a command to activate the sampling mechanism and stores the corresponding event information. The solution helps maintain the continuity, accessibility, and reliability of environmental monitoring data.
