Distributed data acquisition node

1. Distributed data acquisition node product introduction

Distributed data acquisition node is a multifunctional wireless data acquisition system, which can be used for engineering monitoring and security and stability analysis.Distributed data acquisition node is an acquisition system that integrates multi-parameter acquisition and multi-function wireless transmission.It can realize multiple interface protocol conversions and automatically manage wireless data transmission.

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 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 and municipal engineering projects, and high slopes.

2.Distributed data acquisition node application scenarios

Bridges, slopes, tailing mines, water conservancy

3.Distributed data acquisition node product features

1.Quick installation: supports four installation methods: magnetic suction, clamps, hanging ears/bolts, and flexible cable ties, which is fast 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 of arbitrarily configured vibrating wire or RS485 signal sensing equipment, supports internal photovoltaic systems to work independently, or works in conjunction with external photovoltaic (normal power) systems

3.High reliability: adopts fully isolated RS485 communication interface, sensor interface surge protection, power supply anti-reverse connection/over-current/over-voltage protection, improving interface reliability and safety

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

It also supports OTA remote firmware upgrade function to achieve customized algorithm upgrades.

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