Distributed data acquisition node

1.Distributed data acquisition node product introduction

Distributed data acquisition node is a modular distributed data acquisition system that can automatically collect data and can be installed in a wireless distributed manner.Distributed data acquisition node is a collection system that integrates multi-parameter acquisition and multi-function wireless transmission.It can realize multiple interface protocol conversion and automatically perform wireless data transmission management.

It solves the problems of traditional methods relying on module integration, low reliability of hardware wiring, and high maintenance costs.It has the advantages of automatic data acquisition, wireless distributed installation, easy maintenance, and high reliability.

Widely used for monitoring and safety and stability analysis of dams, bridges, subways, transportation municipal projects and high slopes.

2.Distributed data acquisition node application scenarios

Bridges, slopes, tail storage mines, water conservancy

3.Distributed data acquisition node product features

1.Quick installation: Supports four types of installation methods: magnetic suction, clamp, ear hanging/bolt, and flexible cable ties, which are fast and convenient, and are suitable for most installation scenarios; supports local and platform configurations, and are quickly put into use

2.High flexibility: Supports arbitrary configuration of vibrating string or RS485 signal sensing equipment in up to 8 channels, supports the independent operation of internal photovoltaic systems, or work in coordination with external photovoltaic (normal-electric) systems

3.High reliability: Adopt fully isolated RS485 communication interface, sensor interface surge protection, power supply anti-reverse connection/overcurrent/overvoltage relief, improving interface reliability and safety

4.Strong scalability: Based on the modular platform design, the measurement of various physical quantities such as voltage, current, and bridges can be widely compatible with various equipment;

It also supports OTA remote firmware upgrade function to realize customized algorithm upgrade
