SMART PIPE NETWORK MANAGEMENT FLOW METER SUITABLE FOR ESTABLISHING A RESPONSE SYSTEM FOR URBAN FLOODING AND SENSING ENVIRONMENTAL INFORMATION

摘要

Regardless of the case of full or obese pipes, the flow rate and water level can be accurately sensed and the flow rate can be measured from this, and while minimizing the number of sensors, it enables precise flow measurement, and at the same time, sensing not only the flow rate but also the harmful substances in the manhole. It provides a technology that enables integrated management of piping by allowing it to be performed together. To this end, the smart pipe network management flow meter suitable for establishing a system for responding to urban inundation according to an embodiment of the present invention and capable of sensing environmental information is a radar-type first flow rate sensor that measures the flow rate in a non-contact method with the fluid at the top of the fluid. And, a first flow rate measurement unit for measuring the flow rate of the pipe based on the measured flow rate and water level, including a first water level sensor for measuring the water level by the ultrasonic method; A second flow sensor of ultrasonic cross-collation method that is deposited in the fluid and measures the flow rate of the fluid, and a second level sensor and a second level sensor that calculates and measures the level of the fluid according to the pressure value of the pressure sensor that senses the pressure from the fluid. The flow rate of the pipe is measured based on the flow rate and water level measured from the flow rate sensor and the second water level sensor, and the water level value measured from the second level sensor is divided into a preset number of fluid sections, and the second of the divided fluid sections. A second flow rate measurement unit including a flow rate calculator configured to measure the flow rate of the entire fluid using the flow rate of the section to which one fluid section belongs, measured by the flow rate sensor, and the water level and pressure of each fluid section; And when the pipe is obese, the flow measured by the first flow rate measurement unit is determined as the final flow rate, and when the pipe is full, the flow rate measured by the second flow rate measurement unit is determined as the final flow rate. 2 It characterized in that it comprises a; a control unit for determining whether the obesity pipe and the full pipe according to the water level value of the pipe measured by the water level sensor.
