At present, most cities in China are in a serious water shortage. Even in southern cities, there are water shortages or seasonal water shortages. How to irrigate urban landscape plants on the basis of water conservation and build a beautiful new city has become a new topic.
There are many kinds of plants in urban landscapes. Many plants are extremely sensitive to water. Improper water supply and plant growth cannot achieve the desired effect. In case of drought or high temperature, plants will quickly wither and even die. However, the current artificial irrigation methods are backward in technology, and the effective use of water resources is inefficient. The development and implementation of plant maintenance irrigation systems relies almost entirely on the experience of system administrators. Even projects with water-saving irrigation facilities are generally misused, irrigation systems are limited to control, and the system has no monitoring feedback.
Jinglan Yunzhi Internet of Things Technology Co., Ltd. (hereinafter referred to as “Jinglan Yunzhiâ€), as a wholly-owned subsidiary of Jinglan Technology (000711), is committed to becoming China's leading provider of green smart solutions and operational services in the field of ecological cloud. Business. Jinglan Yunzhi has launched a series of solutions using the Internet of Things technology in the field of garden irrigation. The program pays attention to water saving while also timely and precise irrigation, especially the urban intensive irrigation water management. Recently, Jinglan Yunzhi and Jinglan North Garden (Tianjin) Co., Ltd., a subsidiary of Jinglan Technology, jointly implemented two garden irrigation and conservation projects using modern Internet of Things technology in Tianjin.
Project 1: The demonstration project of intelligent water-saving irrigation for garden maintenance in the Airport Economic Zone is located in the green belt of Huanhe East Road and Gangcheng Avenue in Tianjin Airport Economic Zone. It is the two main roads of the Airport Economic Zone. The green area is more than 70,000 square meters.
Before the increase of water-saving irrigation facilities, the project site adopts the traditional artificially managed irrigation method, which has many drawbacks: low irrigation efficiency, waste of water source, affecting the beauty of the city, and high labor costs. This brings a lot of inconvenience to the whole garden maintenance work. The most intuitive economic performance is that the artificial irrigation cost (water fee + labor required for irrigation) accounts for more than half of the entire maintenance cost. Increasing the garden maintenance irrigation system driven by the Internet of Things technology will inject new vitality into the garden conservation work and significantly reduce manual input and other fixed inputs.
The proportion of expenses in traditional garden maintenance
Project 2: “Landing Construction Land Afforestation Project of Binhai New Areaâ€, also known as “Ming Forest†project of container seedling nursery, can be understood as “big bonsai†in a popular way. Plant roots are not directly planted into the soil, but trees are planted in large scale. In the container, the environment can be improved, and the whole container can be moved at any time without damaging the root system, and even as a nursery, and the benefits can be obtained at the right time. Guided by new technologies, the project uses intelligent control of drip irrigation, drone plant protection and other new technologies to save energy and reduce post-conservation costs. The project consists of the second package of the Beijing Blue Garden Awarded Project. The green area of ​​the project is about 400,000 square meters and consists of 7 plots.
The above two projects all adopt Jingya Yunzhi's garden Internet of Things central control system. The system implements real-time control and monitoring functions, supports simultaneous use by multiple users, and supports computer and mobile phone operations. Connect external sensors and equipment, the system has its own pipeline damage and water leakage alarm function, which can realize water volume and water pressure monitoring, and can set irrigation program through water volume.
Through the use of Internet of Things technology, Jinglan Yunzhi Garden IoT Central Control System truly connects data acquisition, equipment management, control execution, monitoring feedback and other equipment to achieve interconnection and interoperability. The garden Internet of Things central control system software is a three-tier structure:
(1) Data layer
The data layer mainly completes the collection and storage of various types of data, such as soil moisture data, meteorological data, plant growth data, and permeability.
(2) Application layer
The main job of this layer is to develop and implement a rotation plan. According to the empirical data of irrigation, as well as the collected meteorological, soil moisture, ET values ​​and other relevant data, a scientific and rational irrigation plan can be formulated.
After the irrigation plan is designed, the control commands are automatically sent to the field unit, and then the pump or valve is turned on or off directly by the field unit or via the RTU. In the process of irrigation, the system adjusts and optimizes the irrigation plan according to the changes in the collected meteorological and soil moisture parameters, such as rainfall stagnation, flooding over-limit irrigation, wind-stopping sprinkler irrigation, etc., and reminds the back-office management whether Implement the irrigation plan in accordance with the new optimization plan.
(3) Interface layer
The user can customize the interface, the interface is graphical, friendly and easy to operate. The customized operation interface is tailored to the needs of the user. The entire interface layer is scientific, beautiful, easy to use and easy to maintain. This layer can provide rich data analysis, display the meteorological parameters of the irrigation area in the irrigation area and the network topology of the entire irrigation area. It can be combined with tools such as GIS to locate the graphical interface of the irrigation system. , can customize the generation of various types of data icons and reports.
The garden IoT central control system is highly innovative, with excellent performance and reliability. It is widely recognized by users. The system perfectly solves the problem of scattered project land. The cloud platform can centrally manage the garden irrigation and water control system of the whole city.
The irrigation system should be specially designed to combine with the management mode. The main function of the system is to manage each sub-device in the irrigation system, monitor the data of each sensor in the system, perform data analysis, and customize the plan report. According to the collected data, a reasonable irrigation plan is established to detect system operation and alarms.
Using IoT technology to irrigate gardens can save 30% of water, while reducing maintenance costs and rational irrigation.
Jinglan Yunzhi Internet of Things Technology Co., Ltd. provides comprehensive technical support (design, supply, integration, support, service and training) for urban irrigation; it can help users to develop irrigation systems based on vegetation planting, according to the plant species itself. The need and meteorological conditions as well as precise irrigation of hydrological data. The system's wireless control, powerful monitoring mode and multi-user management functions can help users to do almost all aspects of management, operation and maintenance, and even directly operate and maintain the system to achieve scientific irrigation in the true sense.
