As China's urbanization accelerates and environmental protection becomes increasingly crucial, water management departments have heavier and wider responsibilities. This in turn has gradually increased the difficulty of water management, operations, and maintenance. The water utility industry will inevitably require constructing an automation and information system, mainly to cover the tasks of municipal water diversion, primary water supply, secondary water supply, urban drainage, sewage treatment, and water resource recycling. HollySys's self-developed products — such as the HiaSCADA integrated supervision and control system (ISCS), LK/LE-series small, medium and large PLCs, and Human Machine Interface — offer a complete set of water solutions from the bottom layer of operations (instrumentation, inverters, pumping station control systems, water treatment control systems) to the upper layer of operation and maintenance information management.
The reform of the natural gas system has gradually turned natural gas into one of China's main energy sources. Gas is widely used in chemical production, power generation, residential utilities, commercial gas supply, urban heating, and automotive fuel. Relying on the HiaSCADA integrated monitoring software, HollySys LK/LE -series small, medium and large PLCs and LKS safety control systems offer integrated solutions for long-distance oil and gas transmission and city gas supply. This includes the monitoring center HiaSCADA integrated supervision and control system (ISCS), SCS field station control system, tank farm monitoring system, ESD emergency stop system, and so on. These work together to achieve monitoring, scheduling, safety protection, and operations and maintenance management for the entire process of oil and gas pipeline, transmission, and distribution. HollySys solutions ensure economical, safe, and efficient oil and gas production and operations. They also enable greater independent control over core control systems in oil and gas transmission.
The urban construction of integrated underground pipe galleries allows for the orderly entry of important urban pipelines, including for water supply, drainage, gas, heat, electricity, communications, radio and television, and industry. It resolves issues of chaotic management between multiple government departments, jurisdictions and consumer units, while contributing positively to flood mitigation, "road zipper" projects (frequent and repeated constructions), and the reduction of underground space resources. The urban pipe gallery integrated supervision and control system (ISCS) follows a "comprehensive integration" construction concept. It is a centralized display, monitoring and management platform for comprehensive pipe gallery information. It integrates security video monitoring, intrusion protection, environment and equipment monitoring, fire warning, fire protection, ventilation, and other systems. It can monitor and manage all manner of facilities within the integrated pipe gallery, such as fire protection, power supply, lighting, ventilation, water supply and drainage, video, identification, security and alarms. The urban pipe gallery ISCS realizes system data sharing and data display and linkage control. It is a core system for dispatching, remote monitoring, operations and maintenance employing a unified data format; it is also a server system and user interface based on cloud computing and mobile devices.
The monitoring system of the urban centralized heat supply network plays a very important role in ensuring the supply of high-quality heat with safe operations, economical energy utilization and conservation, and environmental protection. The system constructs a big data platform of heat supply networks to realize automatic and intelligent data-based management and control while deeply integrating with businesses such as safety assurance, operations and maintenance, emergency command and more, thereby providing auxiliary support for a safe heating supply and operational decisions. HollySys takes the lead in proposing a philosophy of integrated digital heat network control platform for urban heat supply networks. It relies on its own large-scale distributed HiaSCADA integrated monitoring software and PLC control systems to provide an integrated solution for the construction of centralized urban heat supply management and automatic heat exchange station control systems.
