Distributed data acquisition node

1.Distributed data acquisition node product introduction

Distributed data acquisition node is a multi-communication interface, multi-function wireless data acquisition system, wireless distributed installation, easy maintenance.Distributed data acquisition node is an acquisition system that integrates multi-parameter acquisition and multi-functional wireless transmission. It can realize multiple interface protocol conversion and automatically manage wireless data transmission.

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

It is widely used in monitoring and safety and stability analysis of dams, bridges, subways, transportation municipal engineering and high slope projects.

2. Distributed data acquisition node application scenarios

Bridges, slopes, tailings ponds, water conservancy

3. Distributed data acquisition node product features

1. Quick installation: supports four types of installation methods: magnetic suction, clamp, ear/bolt, and flexible cable tie. It is quick and convenient and suitable for most installation scenarios; supports local and platform configuration and can be put into use quickly

2. High flexibility: supports up to 8 channels to arbitrarily configure vibrating string or RS485 signal sensing devices, supports the internal photovoltaic system to work independently, or work in conjunction with the external photovoltaic (normal power) system

3. High reliability: fully isolated RS485 communication interface, sensor interface surge protection, power supply reverse connection protection/overcurrent protection/overvoltage protection, improve interface reliability and safety

4. Strong scalability: Based on modular platform design, by replacing the measurement module, it can realize the measurement of various physical quantity signals such as voltage, current, bridge, etc., and can be widely compatible with various types of equipment;

At the same time, it supports OTA remote firmware upgrade function to realize customized algorithm upgrade

5. Product privacy protection and permission management: Device permission management can be performed for special product applications to protect the rights and interests of product owners
