The accelerating process of urbanization has further expanded the coverage of urban water supply. The original smart water supply system of some water companies is far from meeting the actual demand for water, especially under the current rapid development of Internet of Things technology, smart water supply. The trend of intelligent and automated development of the system has become increasingly apparent. From an overall perspective, the operation of the smart water supply system also tends to shift to the automatic control mode. The automatic control system makes the system operation more stable and reliable. This article takes the water supply system of a county-level water supply company as the analysis object, and expounds the construction route and technical methods of urban smart water supply system.
I. Analysis of the overall structure of urban smart water supply system
The urban smart water supply system is formed by the integration of different levels and subsystems of different service targets. The overall structure has certain complexity and comprehensiveness. Its composition mainly includes: water pipeline monitoring points, central dispatch management network, high level reservoirs Pressure pump station management. The management team mainly uses Ethernet for information exchange, and the management layer and the monitoring layer complete the interaction between the information through the client/server HMI configuration monitoring software. The data information collection is based on the MDLC affected by the transmission distance. Master-slave communication protocol.
Second, urban smart water supply construction path and technology
Due to the limitation of water supply scale, urban smart water supplies are mostly in a hierarchical structure and are based on service-oriented architecture (SOA).
1 software and hardware foundation
The hardware and software basic layer mainly includes various hardware and software equipment needed to build a smart water supply, such as operating systems, database management systems, GIS platforms, water supply information monitoring equipment, servers, and information and communication networks, etc., which are the basis for achieving smart water supply.
2. Smart Water Supply Data Center
The Smart Water Supply Data Center provides solutions for distributed management and functional integration of GIS data and water supply pipe network thematic data and business data. The smart water supply data center includes a data warehouse, a functional warehouse, and a construction platform.
Heterogeneous heterogeneous databases created by smart water systems can organize data formats into a unified data format without changing the original data foundation. Heterogeneous heterogeneous databases in smart water systems integrate various data organically through logic operations. This is very different from the traditional physical integration of data only. Therefore, the smart water supply system can effectively share the data in it, so that the data mining work can be further carried out.
The function warehouse provides multiple water supply business application system integration and function reuse methods, and realizes warehouse-style management of basic water supply functions and special business functions, and is used to directly support the rapid setup and configuration of the system. The functional warehouse can be more easily integrated with the original system, and provide more interfaces for the expansion of the entire system, and do its best to avoid the waste of resources and funds.
Build a platform to provide advanced build, configuration, and plug-in secondary development techniques, and strive to build from all aspects of interface performance to data management. The construction platform mainly supports the establishment of water supply business processes and the construction of water supply business functions, and promotes the application of production-oriented application systems like building blocks; it advocates radically reducing the difficulty of software development by changing development methods; promoting zero coding or a small amount of coding speed Build a water supply business application system, and the business process can be flexibly customized and adjusted flexibly.
3. Smart water service platform
The smart water supply service platform will use the integration of MIS, OA, and GIS, that is, OA is integrated into GIS and MIS, and ultimately constitutes a complete water service platform. The platform can provide data services, location services and management services for town water supply.
Sewing thread silicone oil:
blended with high weight molecular polyorganosiloxane and liquid paraffin. Therefore, the sewing thread will be lubricity, antistatic, wear resistance and smoothness after processed by this thread lubrication.
Sewing thread silicone wax:
After applying this product to the sewing thread, the sewing thread is excellent in antistatic, smooth, high temperature resistance. Compared with the dimethyl oil, the sewing thread using silicone wax is harder to break and have better performance in high speed (7000needles/min)sewing process .
spin oil for Polyester staple fiber: Process chemical for Manufacture PET RE-HCS polyester staple fiber.
Silicone softener for Polyester staple fiber:
it can make the polyester fiber excellent fluffy, rebound resilience, smooth, soft, good handling feeling and high anti-static characteristics, the hollow fiber will be more white and bright after using the finishing agent.
anti-static agent for Polyester staple fiber: Applied to polyester, nylon, polyester and other synthetic fiber for antistatic.
Antistatic agent SN can be used alone, can also be associated with other containing
anionic surfactant, oil, emulsifier prepared into water solution, so that the fiber tow can be eliminate static through emulsion, dosage is generally of fiber weight 0.2~0.5%.
Defoamer for PET sheet cleaning:
sewing thread silicone oil, silicone sewing thread lubricant, silicone wax lubricant, spin oil, Silicone softener, anti-static agent, silicone wax emulsion
