Embodiment Construction

[0010] The invention is an automatic rain gauge station, comprising a rain sensor, an intelligent rain recorder and a power supply. The rainfall collected by the tipping bucket rain gauge 4 of its rain sensor is counted in real time by the counter 5 connected to it, and its counting pulse signal is passed to the micro-power consumption data processor 7 of the intelligent rain gauge; Power consumption data processor 7, LCD display 6, non-volatile data memory 8, telephone modem 9, RS232 interface 10; exist figure 1 In the block diagram of the principle structure of the automatic rain gauge station shown, the rain sensor is formed by placing the counter 5 under the rain dump 16 of the tipping bucket rain gauge 4 . The cylinder body 17 of the tipping bucket rain gauge 4 is supported on the cement base 14 by the support frame 22, and the sensor socket 13 is fixed at the bottom of the cylinder body 17, and the signal cable 12 passes through the threading hole 21 on the support fram...

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 technical scope of automatic measurement, in particular to an automatic rainfall station for collecting ground rainfall information for meteorological detection. Background technique [0002] The traditional way of measuring rainfall is to place a container with a scale in the open air. After a rain, the amount of rainwater collected in the container is manually observed to determine the amount of rainfall. However, the volume of the container often changes due to wind and sand deposition, and the measurement error is very large, and the amount of rainfall cannot be reported in real time. Contents of the invention [0003] The purpose of the present invention is to provide a kind of automatic rain gauge station, comprise the rain sensor that is connected by tipping bucket rain gauge 4 and counter 5, comprise micropower consumption data processor 7, LCD display 6, nonvolatile data memory 8, telephone modem 9 and RS232 int...
