Founded in 2002, Augur Intelligence Technology (Guangzhou) Co., Ltd is an information technology enterprise that provides solutions covering smart water, smart municipal services, and smart urban planning. Its business covers planning and design, consulting, hardware and software production, customized development and integration, and smart city infrastructure maintenance. The company is headquartered in Guangzhou, China, and has sales and research branches in Beijing, Shanghai, Hefei, Changchun, Nanchang, Nanning, Jingzhou, and the South Asia Pacific.
In recent years, great progress has been made in urban drainage. However, traditional smart drainage that uses the GPRS technology for monitoring and management is faced with the following challenges:
- Poor data transmission security
- Limited network coverage
- Difficult maintenance in remote areas
- Shutdown of traditional networks
Why HUAWEI CLOUD IoT
The NB-IoT Smart Drainage solution can resolve common issues faced by traditional smart drainage and the drainage industry.
- An ideal choice to solve common problems in the drainage industry: The NB-IoT Smart Drainage solution monitors equipment status in real time, enabling maintenance personnel to make better decisions and reducing their workload.
- Enhanced data transmission security: The NB-IoT Smart Drainage solution adopts two-way authentication for data transmission, along with strict encryption and dedicated frequency bands for air interfaces. In addition, the IoT gateway serves as a local policy execution device. Underlying networks, such as the cellular network, ensure secure data exchange between domains and provide anti-intrusion protection.
- Expanded network coverage: Compared with LTE networks, the NB-IoT network increases coverage by a hundredfold, covering water facilities in remote areas, factories, underground garages, and manhole covers.
- Easier maintenance: NB-IoT focuses on applications with a small data volume and low rate. Therefore, NB-IoT devices consume little power and their batteries can last as long as several years, making them ideal choices for drainage sensors and monitoring devices which are deployed on high mountains or in the wilderness.
Huawei's advantages lie in ICT technologies. It can build a data center at record pace, which plays a significant role in smart city applications. According to Chen Shunqing, General Manager of Augur, the IoT solutions Augur developed before were distributed in different cities, and now the information they have collected needs to be shared between the cities. Drainage, for example, is a complex systematic project that involves pipe and network construction as well as rain and flood modeling. This requires a large amount of data, and Huawei's information platform is ideally placed to provide support.
Augur and Huawei jointly launched the Smart Rain and Flood Management solution, which provides water workers with digital management tools featuring intelligent management and efficient operations. Developed based on IoT technologies, these tools enable disaster prediction, emergency response, and post-incident optimization, and facilitate innovations in smart rain and flood management through real-time rain and flood monitoring, waterlogging prediction and pre-warning, fully-converged incident command, along with post-incident analysis and evaluation.
- Disaster prediction: If a natural disaster could be predicted just one minute earlier, considerable loss of life and property damage could be avoided. Therefore, it is vital to stay well prepared for waterlogging incidents that may occur, which requires the collection and analysis of a large amount of data. Augur Intelligence deploys a number of intelligent sensors and devices, such as water level gauges, flow gauges, water quality monitoring and water pumping station monitoring devices, which are connected to the Huawei OceanConnect IoT platform. Timely data backhaul through NB-IoT and eLTE-IoT networks with low power consumption helps build a real-time monitoring database at a low cost.
- Emergency response: If emergency strategies can be executed immediately to schedule disaster relief resources after a waterlogging incident occurs, losses can be reduced to a large extent. This requires accurate, dynamic analysis of massive volumes of data and efficient coordination of various resources. Augur's geographic information platform effectively processes geographic and space-related data, precisely manages a large quantity of personnel and equipment, and supports cross-layer and cross-system applications. Huawei's hyper-converged infrastructure (HCI) transfers the capabilities of Augur's geographic information platform to relevant departments, enabling simultaneous pre-warning, intelligent analysis, timely on-site video acquisition, video conferencing for planning, and scheduling of emergency teams. In this way, information is fully shared and resources are centrally scheduled, providing important technical support for an efficient emergency response and planning for Augur's rain and flood management.
- Post-incident optimization: The physical environment information, disaster evolution models, and solution implementation effects accumulated through waterlogging incidents are valuable resources for updating the water resource industry's big data database and emergency plans. Urban rain and flood data are calculated using Augur's professional waterpower model for post-incident status evaluation and re-analysis, providing accurate guidance for subsequent emergency plan optimization and sponge city planning and construction.
In addition, a map with clear topology and accurate drainage facility locations will be generated and enable refined management, dynamic updating, real-time monitoring, and intelligent management and control of drainage facilities in the city. Water flows can be queried, traced, and analyzed in a visualized manner, which provides effective support for emergencies such as sewage overflow, rainstorms, and waterlogging, and facilitates decision-making in sponge city planning and design, drainage facility reconstruction, and emergency scheduling.
- Economic benefits
After this solution is implemented, emergency personnel can be optimally scheduled. This would save a city of 10 million people as much as 2000 person-days of labor each year. Improvements in infrastructure planning can help cities avoid repeated construction, saving over US$700,000 in costs. In addition, the use of NB-IoT devices reduces overall maintenance frequency by 30% and saves up to 35% in maintenance costs.
- Social benefits
1. Scientific management
Through industry innovation, refined and smart drainage operations and management are available to monitor drainage facilities in real time, strengthening scheduling and emergency handling capabilities, enabling secure drainage, and improving O&M efficiency and service quality. The government can focus on designing and developing urban drainage facilities in a data-based manner to ensure all-round and sustainable waterlogging prevention and pollution control.
2. Stronger protection
Systematic construction reduces the number of waterlogging areas and the risk of waterlogging to safeguard property in those areas. In addition, sources of urban water pollution are eliminated to protect the health of the local population.
3. Better environment
The smart drainage system facilitates scientific water treatment to improve the urban environment and resolve various social issues caused by pollution.
4. Improved livelihood services
The smart drainage system prevents urban waterlogging and water pollution and creates a harmonious, beautiful, clean, and safe city for urban residents.
5. Accelerated economic and social development
The smart drainage solution accelerates intelligent urban development, eliminates waterlogging and pollution, improves livelihood and production, stimulates tourism and consumption, and contributes to economic and social development.
With the various cloud services and comprehensive platforms provided by HUAWEI CLOUD, Augur is able to focus on the service application and perception layers without the burden of maintaining its own computing and storage, as the company expands into smart city solutions. The Smart Rain and Flood Management solution enables fast project construction and reduces annual costs by 60%, compared with traditional self-built resources. In addition, comprehensive product lines and services provide support for future upgrades, allowing Augur to focus on its core business and better serve its customers.
