On Power Supply

On Networking

1. No signal coverage: Data transmission relies on operators’ cellular networks, which are limited by base station deployment. Communication quality and reliability cannot be guaranteed in remote rural and wild areas—precisely the key areas for reservoir informatization. A highly reliable, large-capacity and high-bandwidth private network is therefore a necessity.
2. Insufficient capacity: Real-time monitoring of rivers and reservoirs requires large-capacity IP HD video transmission. Restricted by frequency resources and base station capacity, 4G/5G networks cannot support concurrent transmission of multiple video streams in a single area, and a genuine broadband IP private network system is a must.
3. Exorbitant costs: Smart Water Conservancy systems generate massive data traffic, especially HD video surveillance—one single 1080P HD camera consumes 1,000–2,000 GB of data monthly. Adopting 4G/5G would result in prohibitive ongoing traffic fees, making 24/7 continuous operation unfeasible and rendering the system a mere formality.
4. Poor security: Networking via 4G/5G public networks is underpinned by the open Internet, exposing servers and databases to cyberattacks, system sabotage and data theft by hackers. If this method must be used, Guoxin Longxin’s Virtual Private Network (VPN) solution is strongly recommended to maximize system security and availability. For details on the 4G/5G VPN solution for government and enterprise clients, refer to the document 5G Virtual Private Network Solves Networking Challenges for Government and Enterprise Clients.

Taking the construction of a smart system for a certain reservoir as an example, the design concept of the solution is as follows:

IP cameras, water quantity and level sensors, etc., can be deployed at the front-end monitoring points of the reservoir for real-time collection of images and operational data. The information from these front-end points is then transmitted back to the command center via a wireless IP network, enabling 24/7 uninterrupted monitoring and scientific management of information points and key locations around the reservoir.

A dedicated iMAX high-bandwidth wireless network system is adopted to interconnect the networks of all access points (e.g., pumping stations, rainfall stations, hydrological stations, sluice gates, etc.) within the reservoir monitoring area. Through this network, collected data (such as rainfall, wind speed, water flow, velocity, water quality, etc.) and high-definition IP video surveillance information are transmitted collectively to the command center. Meanwhile, various control commands can be sent to on-site instruments and equipment in real time, achieving remote intelligent control of sluice gates and pumping stations. This not only improves the efficiency of daily reservoir management, but also plays a crucial role in water volume regulation for flood prevention and control.

If Guoxin Longxin’s iMAX 5G system—a dedicated outdoor ultra-long-distance communication solution—is adopted for networking, a small-to-medium reservoir typically only needs 1 to 2 base stations (BS) built at commanding heights in the area to achieve full wireless coverage for circumferential monitoring. As long as high-bandwidth wireless CPEs are installed at the scattered monitoring points around the reservoir, convergence of images and data, as well as transmission of control signals, can be realized, forming a genuine “multi-network convergence” system.

Typical application topology diagram for reservoir/dam monitoring is shown below:

Comprehensive monitoring along river courses differs from that of reservoirs, yet they share common features, mainly reflected in network architecture. Due to the narrow linear distribution of information points along river courses, the network mainly adopts a two-tier wireless networking structure (i.e., backbone wireless network plus access wireless network), or a “multi-hop chain + hot standby redundancy” networking architecture. All other aspects are similar to the comprehensive monitoring of reservoirs.

The typical application topology diagram for river course monitoring is shown below:

Many monitoring points in reservoir areas operate in harsh, unattended environments, and only the iMAX transmission system with high reliability, ultra-long transmission distance and non-line-of-sight wireless capability can meet such operational requirements. Designed to build wireless cities and enable ultra-long-distance outdoor network interconnection, all series of iMAX wireless communication devices deliver extended transmission ranges. Among them, the iMAX-6000 series serves as the communication backbone network, and the iMAX-8000H/S series as the access network.

★ Transmission Distance: Under line-of-sight conditions, even the compact iMAX 5G dedicated communication system with integrated antennas can easily achieve 10-kilometer radius coverage in point-to-multipoint mode; in point-to-point mode, the maximum transmission distance exceeds 100 kilometers.

★ Transmission Bandwidth: The iMAX-8000H is a 600 Mbps point-to-multipoint communication system, the iMAX-8000S is a 100 Mbps point-to-multipoint communication system, and the iMAX-6000 is a point-to-point wireless backbone network communication system with bandwidth options of 150/300/600 Mbps.

The seamless integration of iMAX wireless metropolitan area network technology and iPower lithium new energy technology is truly a golden combination for deploying IT information points in outdoor environments.
