Anti-freeze rain gauge based on infrared distance measurement and control method

Abstract

The invention discloses an anti-freeze rain gauge based on infrared distance measurement and a control method. A shell is internally provided with a water container and a measuring cylinder. An intakepipe leading to the measuring cylinder is arranged at the bottom of the water container, and the intake pipe is equipped with a first solenoid valve. A drainage pipe is arranged at the bottom of themeasuring cylinder, and the drainage pipe is equipped with a second solenoid valve. Heating devices are arranged at the bottoms of the water container and the measuring cylinder and on the water intake pipe and the drainage pipe respectively. Temperature sensors are arranged at the water container and at the measuring cylinder respectively. A foam floating plate is arranged in the measuring cylinder, and an infrared distance sensor is arranged on the top. The rain gauge further includes a control unit. The temperature sensors and the infrared distance sensor transmit the collected data to thecontrol unit. The control unit controls the on-off of the heating devices and the two solenoid valves, and obtains rainfall information according to the data collected by the infrared distance sensorand sends the rainfall information to a monitoring center. The problem of rain gauge failure caused by rainwater freezing at temperature below 0 DEG C is solved. Remote monitoring of rainfall is realized. Data support is provided for geological disaster preventing or warning.

Description

technical field [0001] The invention relates to the technical field of rainfall monitoring, in particular to an antifreeze rain gauge based on infrared ranging and a control method. Background technique [0002] Rainfall measurement is for liquid or solid melted water falling from the sky to the ground. my country belongs to the East Asian monsoon region in the regional climate pattern, and heavy rains are very frequent in mountainous areas. Geological disasters caused by heavy rains not only cause devastating blows to infrastructure, but also to people. People's life safety poses a great threat. Therefore, it is particularly important to accurately measure rainfall and transmit it to the monitoring center in real time. The rain gauge is an instrument used for meteorological monitoring and hydrological monitoring to measure rainfall. There are four types of heavy rain gauge, tipping bucket rain gauge and ultrasonic rain gauge. [0003] The siphon rain gauge is mainly compos...
