DQA-IOT NB-IOT/LoRa Wireless Current Acquisition Terminal

 

1 Product Overview

 

DAQ-LP-CT01 wireless current acquisition sensor terminal is equipped with low power consumption and high sensitivity of the open type transformer, through the principle of electromagnetic induction, the primary side of the large current into the secondary side of the small current, and then used for current monitoring, can be very sensitive to detect the size of the line current, and at the same time to the designated platform server wireless reporting data.

The terminal adopts NB-IOT/LoRa communication mode to overcome the wireless communication block caused by the special environment of the site, greatly simplifying the site deployment time and reducing the construction cost. Device working states include hibernation, collection and storage, and activation and reporting. This terminal is equipped with a wide range of open and close transformers, wide range of current measurement, high-quality magnetic core materials, open and close structure, easy to install, for AC motors, lighting equipment, air compressors, heating ventilation and air conditioning devices, building self-control system, industrial urban network, rural power grid transformation projects and other scenes of current monitoring and collection.

4 Micropower operating mode

The wireless current acquisition terminal achieves the effect of power saving through intermittent work, the device is in standby state most of the time, and only a small part of the circuit continues to work to maintain the state of micro power consumption. This part of the circuit will ensure the correct operation of the system time and the correct record of the next activation time.

Daily power consumption calculation of the device: Daily working states are divided into: standby state and working state (wake up data collection and upload data through GPRS/NB-IOT), corresponding to different state power consumption data.

5 Product core advantage

Ø Built-in battery, no wiring required.

Ø Simple installation, fast deployment, help the Internet of things project quickly landing.

Ø Support any private Internet of Things cloud platform and configuration software, and provide data protocol docking.
