Embodiment Construction

[0012] The present invention is an automatic rainfall station, which is an instrument used to collect ground rainfall information. Mainly used in meteorology, hydrology, agriculture, environmental protection and other fields. The system is powered by a 12V solar system. It can be used as an automatic rainfall recording instrument, or it can be connected to a computer to analyze data at any time to form a telemetry automatic rainfall station. The methods are as follows: connect directly with the PC through the cable through the RS232 interface 10; connect with the PC through the telephone line socket 11 through the city telephone system; or connect with the PC through the GSM handwriting communication system; or connect with the UHF / VHF radio. The tipping bucket rain gauge is used as the rainfall collection sensor, and the rainfall data collected by the sensor is converted into a pulse signal by the reed switch counter, which is transmitted by the signal cable 12 to the low-power d...

Abstract

The station comprises the rainfall sensor, the intelligent rainfall recorder and power supply. The counter under the rainfall skip bucket makes real time counting and transferring the counting pulse signal to the intelligent rainfall recorder. The recorder comprises data processor with micro power consumption, the LCD display, non-volatile data storage, the phone modem, RS 232 interface etc, and the DC power source supplied by the accumulator charged from the solar battery supports the system. The counting accuracy reaches 0.1mm. The data acquisition memory system in low-power dissipation and large capacity is supported by lithium battery. The recorded data can be saved for more than ten years without losing any data under complete electroless condition. The device can be connected to PC for data analysis constituting the remote type automatic rainfall station suitable to be installed in field for networked observing, recording saving and querying.

Description

Technical field [0001] The invention belongs to the scope of automatic measurement technology, and particularly relates to an automatic rainfall station for collecting ground rainfall information for meteorological detection. Background technique [0002] The traditional rainfall measurement is to place a scaled container in the open air. After a rain, manually observe how much rainwater is collected in the container to determine the rainfall. However, the volume of the container often changes due to the deposition of wind and sand, and the measurement error is very large, and the rainfall can not be reported in real time. Summary of the invention [0003] The purpose of the present invention is to provide an automatic rain gauge, including a rain sensor, an intelligent rain recorder and a power supply, characterized in that: the rain collected by the tipping bucket rain gauge 4 of the rain sensor is counted in real time by a counter 5 connected to it. , Transmit its count pulse...
