Contactless water velocity measuring sensor, automation device, and urban water network intelligent monitoring system

Abstract

A contactless water velocity measuring sensor is characterized by comprising a laser, two light sensors, a reflector and a transparent pipeline. The reflector is capable of reflecting more than 80% of the light. The laser and the reflector (S5) are arranged on both sides of the transparent pipeline respectively. The contactless water velocity measuring sensor is used for measuring the flow velocity of a transparent fluid (S3) flowing through the transparent pipeline. The laser emitted by the laser first passes through the transparent fluid in the transparent pipeline, is then reflected by the reflector to pass through the transparent fluid again and then to irradiate the light sensors. The same spot of the laser emitted by the laser irradiates the two light sensors at the same time. The laser, the two light sensors, and the transparent pipeline (S2) are relatively fixed. The contactless water velocity measuring sensor, an automation device having the sensor and an urban water network intelligent monitoring system having the sensor are used for monitoring vibration. The contactless water velocity measuring sensor is simple in structure, low in cost and easy to machine, and provides a new sensor design idea.

Description

technical field [0001] It involves the field of sensors, specifically non-contact water speed measurement sensors, automation equipment, and an intelligent monitoring system for urban water networks. [0002] technical background [0003] Existing sensors are expensive, require high machining accuracy, high cost, and complex structures. Sensors are important components for robots to ingest environmental information. If the sensor is expensive, it will be the threshold for the popularization of robot technology and hinder the intelligent era. The development of the development of the great rejuvenation of the Chinese nation is hindered, and the development of various low-cost sensors is very necessary for the development of robotics and smart cities. [0004] The more sensitive the sensor is, the more accurate it is, and the easier it is to sense small environmental changes. The more sensitive the sensor, the better the high-speed response of the device. The existing high-sens...
