New Smart IC Card Water Supply Controller

technical field

The utility model relates to the technical field of devices with prepaid basic fees, in particular to a novel intelligent IC card water supply controller.

Background technique

Water is the source of life, the key to production, and the foundation of ecology. It is imminent to fully implement the Chinese government's opinions on implementing the strictest water resources management system, promote the construction of the strictest water resources management system and improve the river basin water resources management system. In January 2012, the Chinese government issued the Opinions on Implementing the Strictest Water Resources Management System, making systematic arrangements for the implementation of the strictest water resources management system, and clarified the control of water resource development and utilization, water use efficiency control, and water function zone restrictions on pollution. "Three Red Lines" control indicators: By 2020, the total amount of water used in the country will be controlled within 670 billion cubic meters, the water consumption per 10,000 yuan of industrial added value will be reduced to less than 65 cubic meters, and the effective utilization coefficient of farmland irrigation water will be raised to above 0.55. The water quality compliance rate of the lake water function zone shall be increased to more than 80%; by 2030, the total water consumption of the country shall be controlled within 700 billion cubic meters, the water consumption of 10,000 yuan of industrial added value shall be reduced to less than 40 cubic meters, and the effective utilization coefficient of farmland irrigation water shall be increased If it reaches 0.6 or above, the rate of water quality compliance in water function zones will increase to over 95%.

In 2011, the No. 1 Central Document proposed that “the most stringent water resource management system should be implemented. It is required to establish a total water consumption control system, establish a water use efficiency control system, and improve the information level of water resource regulation, water conservancy management and project operation. Water conservancy information Modernization drives the modernization of water conservancy".

Implementing the most stringent water resources management system is an extremely complex systematic project, a revolutionary change to the traditional growth mode, and requires the joint efforts of the whole society. First, we must firmly establish the concept of people-oriented and harmony between people and water, accelerate the transformation from water supply management to water demand management, from development and utilization to development and protection, from extensive and inefficient use to economical and efficient use, and from administrative management to comprehensive Management transformation to promote the coordination of economic and social development with water resources and water environment carrying capacity. Second, we must promptly implement the control indicators of the "three red lines" of water resource development and utilization control, water use efficiency control, and water functional area restrictions on pollution. The third is to speed up the construction of water resources allocation and the connection project of rivers, lakes and reservoirs, and gradually build a macro-allocation pattern of water resources with "four horizontals and three verticals, north-south allocation, and east-west mutual aid", as well as smooth diversion and drainage, proper storage and discharge, and adjustment of abundance and dryness. A water network system of rivers, lakes and reservoirs that complement each other and can be adjusted freely strengthens the unified and scientific regulation of water resources. Fourth, we must comprehensively promote the construction of a water-saving society, focus on water conservation and pollution prevention in the fields of industry, agriculture, and urban life, and do a good job in waste water treatment and reuse, rainwater collection and storage, and seawater direct utilization and desalination utilization. Fifth, we must establish and improve the planning system for the rational allocation, efficient use, and effective protection of water resources, improve relevant supporting laws, systems, and standards, refine various policy measures, and vigorously promote the legalization of water resources management. Sixth, we must strengthen water resource monitoring capabilities and scientific and technological support, and gradually establish central, river basin, and local water resource monitoring and management platforms and information management systems to comprehensively improve monitoring, early warning, and management capabilities. Seventh, we must deepen the reform of key areas and key links such as the water resource management system, water affairs management system, and water price formation mechanism, actively explore the establishment of water rights and water market systems, and strive to break the institutional and institutional obstacles to water resource management. Eighth, we must implement the main body responsible for water resources management of local governments, strengthen assessment and supervision, increase publicity on national conditions and water conditions, strengthen coordination and cooperation between departments, river basins, and localities, and form a joint force for water resources management.

In terms of groundwater resources management, IC card management has been adopted in recent years, and the management method of "paying the fee first, then taking water, swiping the card to take water, and taking the card to stop the water" has achieved the purpose of economic regulation of water resources and total control. A wide variety of IC card water supply controllers.

Various data, such as water level, pressure, switch status, etc.; and in terms of applicability, only specific product application occasions are considered, ignoring the general requirements of the product, there have been IC card water supply controllers for electromechanical wells, pipeline IC card water supply controllers, Channel IC card water supply controllers and other products with various names have poor versatility. Even in the field of electromechanical wells, there are products of different sizes because of the different power of the water pumps.
