Wireless Level Monitoring

System Requirements Analysis
Monitor water level and temperature data in open-pit mines. Issue a warning when the water level is about to exceed the river's warning line. Simultaneously, report data exceeding normal values to the relevant department's monitoring center, monitor water quality, protect the river's water environment, and provide data for the supervision of illegal discharge and leakage.

Application Challenges:
1. Difficulty in power supply and signal transmission;
2. High equipment maintenance costs.

Solution Advantages:
1. Provide low-power products with battery and solar power solutions;
2. Integrated structure, strong anti-interference ability, stable and durable;
3. Provide a remote wireless IoT solution.

I. On-site Requirements

1. Measurement Object
Firefighting water pool water level monitoring.
2. Network Environment
There is a wireless network signal on-site, and the Mobile phone can make calls normally.
3. Data Transmission
Measured values need to be sent to the big data platform regularly, and users can monitor them in real-time via their Mobile phones, once a minute or once every 10 minutes (this value can be set by the user).
4. Equipment Protection
Most installation points are in humid indoor environments; the equipment needs to be damp-proof, waterproof, and dustproof.
5. Equipment Power Supply
Wired power supply prefers DC24V (consistent with fire-fighting equipment); wireless transmission prefers battery power:
6. Equipment Installation
Installation points can be centralized or dispersed. For centralized installation locations, shared information transmission devices should be considered.
7. Alarm Function
The remote monitoring terminal needs to display fault information in time, and the water level monitoring equipment needs to have overload protection.
System Composition
Composed of network transmission layer and system application layer. The remote monitoring system for the fire water system mainly consists of the front-end sensing layer
Mainly includes:
System software: Dongfang Wanhe sensor big data platform Fire remote monitoring platform (B/S).
Communication platform: GPRS network/full network access/NB-IOT network.
Acquisition and transmission equipment: WH311 intelligent wireless liquid level transmitter.
