Embodiment 1

[0060] This embodiment provides a device for automatically measuring precipitation, such as figure 1 As shown, it includes a rain opening 1 with a spout 6 and a precipitation measuring cup 2 arranged below the spout 6 , and also includes a precipitation judging module 3 . According to the standard for measuring precipitation, the diameter of the precipitation measuring cup 2 is 4cm, and the diameter of the rain holding port 1 is 20cm.

[0061] like figure 2 As shown, the precipitation judging module 3 includes an L-shaped precipitation judging sensor 31 and a monitoring unit 32; the L-shaped precipitation judging sensor 31 is placed in the precipitation measuring cup 2, includes an L-shaped insulating plate and is arranged on the Describe some judging contacts A on the L-shaped insulation board i , each of the judgment contacts A i The resistance value of ≈0, and 0≤i≤n, n is a natural number, here, each of the judgment contacts A i Select a conductor with good electrical ...

Embodiment 2

[0085] This embodiment makes the following improvements on the basis of Embodiment 1:

[0086] The terminal controller also includes a wireless communication interface 324 and a data output unit 325;

[0087] The wireless communication interface 324 sends the line information, precipitation information or precipitation data of the breakpoint to the upper computer of the relevant management department;

[0088] Further, the data output unit 325 outputs line information where the breakpoint is located, precipitation information or precipitation data.

[0089] Correspondingly, as an improvement, a measurement method using the above-mentioned device for automatically measuring precipitation provided by this embodiment further includes the following steps:

[0090] S8: Use the wireless communication interface 324 to receive the signal output by the judgment analysis processing unit 323, and then send the line information, precipitation information or precipitation data at the brea...

Embodiment 3

[0095] The judgment contact A 0 with the judgment contact A 1The distance between is preferably 1.5cm, because the diameter of standard precipitation measuring cup 2 is 4cm, judging contact A 0 with the judgment contact A 1 The distance between them is 1.5cm, which is convenient to put the L-shaped precipitation judging sensor 31 into the precipitation measuring cup 2, and the judging contact A 0 with the judgment contact A 1 It is also easy to realize precipitation conduction between them; the judgment contacts A arranged at equal intervals along the direction away from the bottom of the precipitation measuring cup 2 2 to the judgment contact A n The equidistant distance between the judging contacts between is preferably 1mm, although the interval between each judging contacts can be selected according to the requirement of judging accuracy, in theory, the smaller the interval, the higher the accuracy, but the engineering quantity of wiring is also The larger, so in orde...

Abstract

The invention relates to an automatic precipitation measurement device and a measurement method. The automatic precipitation measurement device comprises an L-shaped precipitation determination sensor formed by an L-shaped insulation board and a plurality of determination contacts Ai arranged on the L-shaped insulation board and a monitoring unit, wherein one ends of the determination contacts Ai are communicated with a power source anode V+ through resistors R, the other ends of the determination contacts Ai are connected with nodes Ji to be determined on the monitoring unit, the monitoring unit is connected with a power source cathode or a determination end point C through controlling the nodes Ji to be determined, whether equipment is at fault is determined according to voltage magnitude of the determination end point C, whether rainfall occurs is detected, and precipitation data is detected. According to the automatic precipitation measurement device and the measurement method, whether the rainfall occurs can be detected timely, a precipitation detection mode is simple, once the equipment is at fault, alarm information can be emitted instantly, so problems that whether the rainfall occurs can not be detected and the precipitation detection mode is complex existing in the prior art are effectively settled.

Description

technical field [0001] The invention relates to a device for measuring precipitation, in particular to a device capable of automatically measuring precipitation, which belongs to the field of meteorological observation. Background technique [0002] The impact of weather conditions on traffic cannot be ignored. Precipitation and snowfall will cause slippery road surfaces and cause traffic accidents, especially heavy rainfall and heavy snowfall, which will have a great impact on people's travel and even cause serious consequences. Therefore Timely determination of whether there is precipitation and precipitation data and timely release of early warning information will guide the public to arrange travel plans and avoid unnecessary congestion and damage. [0003] At present, the method commonly used by meteorological departments to measure precipitation is to use a special precipitation measuring cup. Specifically, a 20cm-diameter rain opening is used to receive rainwater, an...
