Instrument remote wireless measuring and controlling management system

Abstract

The invention relates to a wireless remote measurement, control and management system for instruments and meters, which consists of the instruments and meters, an analog-to-digital conversion module, an RJ45 Ethernet network interface module, wireless bridges, a host computer and a computer display screen member, wherein the instruments and meters are converted into digital signals through the 'analog-to-digital conversion module' and connected to a wireless bridge 1 by a network line through the RJ45 Ethernet network interface module; and the wireless bridge 1 is connected to a wireless bridge 2 through wireless bridging, connected to the host computer through a network line and connected with a computer display screen. In outdoors, the wireless remote measurement, control and management system is supplied with power by a solar battery array, a storage battery and a DC-DC converter, and can also be supplied with power by 220V alternating current; a computer terminal is provided with system software; test values of the instruments to be measured can be displayed on a computer and recorded into a database of the host computer; and when the test values read in real time reach alarm values set for the instruments, the computer terminal can give out alarm signals, remind operators on duty to handle the problem in time, and prevent the accident from being enlarged.

Description

technical field [0001] The invention relates to the recording, storage, alarm and network transmission of instrument test data, in particular to a remote wireless measurement control management system for instruments and meters. Background technique [0002] The testing of various instruments and meters is carried out by the instruments and meters on-site at the target object to be tested, and the test data is displayed on the instrument. For some relatively high-end instruments, at the test site, the instrument communicates with the computer through a serial (RS232 / RS485) interface. Connect, analyze the measured data through the computer to judge whether the current situation of the measured object is normal, and save the measured data in the computer at the same time, so as to compare the data before and after, and ensure the safe and normal operation of the measured object. [0003] Some instruments need to measure and record the measured data on a regular basis or even e...

AI Technical Summary

Problems solved by technology

[0003] Some instruments need to measure and record the measured data on a regular basis or even every day, and some instruments are operated outdoors. In this way, the instruments and computers must be installed and disassembled every time the measurement is performed. The workload is heavy and the work efficiency is not high. , and the instrument and computer are often disassembled and moved, which is easy to cause damage
