Program Background
The flood control project is a major livelihood project and a major ecological project. Based on the background of frequent floods in our country, small reservoirs are important infrastructure for flood control and flood control. It is very necessary for rainwater forecasting and dam safety monitoring, which can not only provide a large amount of reliable data and information for flood prevention and flood control decision-making , and can play an important role in flood control and disaster relief and protection of people's lives and property. Therefore, based on the principles of overall coordination, practicality and effectiveness, information sharing, and adapting measures to reservoir conditions, Jixunwulian makes full use of the new generation of information technology and independently develops an integrated solution for small reservoir rainwater forecasting and dam safety monitoring to realize small reservoirs. Digital, networked and intelligent management ensures the safe operation of the reservoir and benefits the people.
02Needs
Analysis
1. Manual observation is used for water and rain forecasting of small reservoirs, and the level of information management is low, which cannot guarantee the safety of surveyors; 2. The
forecasting data is inaccurate, the rate of false positives is high, and the timeliness is not strong, so it is impossible to grasp the rainwater situation information data of small reservoirs in real time ; 3. The conversion rate of achievements is low, and it is impossible to realize the integrated monitoring of the "four forecasts" of forecasting, early warning, rehearsal and pre-plan.
3. The conversion rate of results is low, and it is impossible to realize the integrated monitoring of the "four forecasts" of forecasting, early warning, rehearsal, and preplan.

Solution
Jixun IoT's integrated solution for small reservoir rainwater forecasting and dam safety monitoring consists of a perception layer, a transmission layer, and a platform layer.
Picture
1
The sensing layer
connects the Jixun IOT water conservancy telemetry terminal with cameras, rain gauges, ultrasonic liquid level gauges, piezometers and other equipment to monitor and collect information such as water level, rainfall, flow, pressure and other information of small reservoirs in real time. Dam seepage pressure, displacement, surface deformation and other data.
2
Transmission layer
Through the communication function of the Jixun IoT water conservancy telemetry terminal, the data related to the rainwater condition of the small reservoir and the dam safety information are transmitted to the Jixun IoT monitoring platform.
3.
The platform layer
can display the water level, flow rate, flow velocity, water quality, gate opening degree, moisture content and other data of small reservoirs in real time in the platform system, and comprehensively display them in the form of charts. At the same time, it can perform calculation analysis and forecast forecasting to provide flood control and disaster relief. Scientific basis and effective information sharing to ensure the safety of people's lives and property.

products
Jixun IOT water conservancy telemetry terminal plays a particularly important role in the integrated solution of small reservoir rainwater forecasting and dam safety monitoring. Real-time collection, reporting and processing of water level, precipitation, flow, flow velocity, Water quality, gate opening degree, moisture content, etc., as well as dam seepage pressure, displacement and other data. This series of products are compatible with industrial protocols such as Modbus tcp/rtu, profibus-dp, profinet, opc, ua, etc., and realize the interconnection and intercommunication of many devices efficiently.
In addition, Jixun IoT water conservancy telemetry terminal also adopts GNSS technology, with a plane accuracy of ±(2.5+ 1×10-6×D) mm and an elevation accuracy of ±(5+1×10-6×D) mm.
This series of products has a variety of models, including water conservancy telemetry terminal TY511, miniature telemetry terminal TY501, gateway type water conservancy telemetry terminal TY910, etc.
05Product
function
1. Jixun IOT Water Conservancy Telemetry Terminals all adopt industrial-grade components and have EMC three-level protection. In the environment of small reservoirs, they can effectively prevent moisture, lightning, and electromagnetic interference, and the moisture resistance can reach 0%-95. % No condensation; at the same time, it uses metal as the machine shell, with IP30 protection level, suitable for various environments with harsh conditions.
2. The water conservancy telemetry terminal provides connection services for different manufacturers and different types of equipment, and supports monitoring of dam displacement, seepage pressure, etc., as well as water and rain data such as water level, flow, and flow velocity of small reservoirs. It is simple to deploy and control, plug and play, and can be Effectively save manpower and material resources; In terms of communication, this series of products also supports network switching such as WAN, LAN, ADSL, GPRS, WIFI, 5G, etc. If the device fails or has an abnormality, it can automatically restart the device and realize the permanent online of the device 7 24 365 hours .
3. The location of small reservoirs is generally remote and the environment is harsh. The Jixun IoT water conservancy telemetry terminal supports multiple heartbeat detection mechanisms such as TCP, DCUDP, and DCTCP. It can quickly and automatically reconnect when the device is powered off or disconnected, which can meet the needs Human-on-duty environmental requirements; in addition, in the state of insufficient power, this product can also use solar energy to power the device.
4. It has the integrated monitoring functions of forecast, early warning, rehearsal and pre-plan "four pre-plans", which can send out alarm signals in time when an emergency occurs, which helps relevant responsible persons to take timely measures and command and dispatch emergency plans, so as to ensure small reservoirs The lives and properties of residents in the surrounding environment are safe, and at the same time, labor costs and economic costs can be greatly reduced.
