Micro-power-consumption tipping bucket type rainfall pulse signal collecting device and method

Abstract

The invention relates to a micro-power-consumption tipping bucket type rainfall pulse signal collecting device and method. The device comprises a first attendant circuit, a second attendant circuit, a working circuit, an attendant power source and a working power source. The first attendant circuit and the second attendant circuit are CMOS logic circuits of the micro-power-consumption design, the working current of each attendant circuit is in microampere level, and the working power source has the switch-on state and the switch-off state, and is in the switch-off state when it does not rain. The first attendant circuit locks and stores a pulse signal of a dipping bucket type rainfall sensor when it rains and generates an awakening signal. The second attendant circuit receives the awakening signal and controls the working power source to be switched on so as to supply power to the working circuit. The working circuit reads the pulse signal locked and stored by the first attendant circuit and controls the second attendant circuit to switch off the working power source after data processing is carried out on the pulse signal. The micro-power-consumption tipping bucket type rainfall pulse signal collecting device has the advantages of working in the microampere power consumption state when it does not rain, being capable of saving energy, and prolonging the service life of a one-shot battery.

Description

technical field [0001] The present invention relates to the technical field of data acquisition, in particular to a device and method for acquiring pulse signals of tilting bucket rainfall sensors with low power consumption, which are used for collecting pulse signals of tilting bucket rainfall sensors in automatic monitoring fields such as water conservancy, hydrology, urban and rural flood control, and geological disasters. The power consumption of the pulse signal data acquisition device is comprehensively reduced, and at the same time, the loss of the rainfall pulse signal is avoided.
