Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 , figure 2 Shown, laser raindrop spectrometer heating control method of the present invention comprises the following steps:

[0016] 1) Obtain the output voltage value U(t) directly from the receiver at each sampling time t of the laser raindrop spectrometer.

[0017] 2) According to the U(t) value obtained at time t and the preset threshold value U min , U max Row comparison; where the threshold U min =U 0 +ΔU max , U 0 is the minimum measurable voltage of the receiver, ΔU max is the voltage value corresponding to the maximum raindrop extinction; threshold U max is the maximum output voltage value of the receiver.

[0018] 3) When U(t)≤U min , start the laser raindrop spectrometer transmitting and receiving end heating device, and return to 1); when U(t)>U min , go to the next step 4).

[0019] 4) Determine wheth...

Abstract

The invention discloses a heating control method of a laser raindrop spectrograph. A nontraditional method is used to control heating of the emission and reception ends of the laser raindrop spectrograph via a temperature sensor, and further to eliminate coagulum or attachment, influence of factors including air humidity and atmospheric composition on heating control is overcome, electric energy needed by heating is saved, and the measuring capability and precision of the laser raindrop spectrograph can be improved substantially.

Description

technical field [0001] The invention belongs to the field of atmospheric science and automatic control, and in particular relates to the heating control of a laser raindrop spectrometer used for measuring precipitation. Background technique [0002] The laser raindrop spectrometer can measure falling rain, hail, snow and other precipitation, can calculate the rain intensity, rainfall and atmospheric visibility of various rainfall types, and can also correct weather radar data. In recent years, with the introduction of laser raindrop spectrometers in Germany, the United States and other countries, and the emergence of domestic laser raindrop spectrometers, various laser raindrop spectrometers have been widely used in my country's traffic control, meteorological monitoring and services, scientific research, airport observation , highway meteorological monitoring, hydrogeography, weather radar data correction and other application fields. [0003] The laser raindrop spectromete...
