Telemetering terminal for preventing missing report of rainfall

Abstract

The invention provides a telemetering terminal for preventing missing report of rainfall, which comprises a first detection branch, a second detection branch, a first tipping bucket, a connecting plate, a second tipping bucket, an installation bracket, an acquisition signal output module and a main control module. According to the telemetering terminal for preventing missing report of rainfall, the first tipping bucket and the second tipping bucket are linked through a seesaw structure, and when the first or second tipping bucket gets stuck in the process of dumping rainwater at the lowest point of the trajectory, the first or second tipping bucket at the lowest point of the trajectory can be moved by prying through the second tipping bucket at the highest point of the trajectory or through the weight increase of the second tipping bucket, so as to ensure the smoothness of movement of the first and second tipping buckets. Therefore, the automatic adjustment ability of the first and second tipping buckets for abnormities can be improved, the risk that a single tipping bucket cannot be overturned in time due to the blockage of foreign bodies is avoided, and the accuracy of rainfall measurement by the first and second tipping buckets through back-and-forth turning in the process of rainfall statistics can be improved.

Description

technical field [0001] The invention relates to the technical field of rainfall monitoring, in particular to a remote measurement terminal for preventing missing rainfall reports. Background technique [0002] At present, the rainfall telemetry terminal in our country is implemented through a dry contact output by the rain sensor, which is connected to the rainfall collection interface of the terminal as a trigger signal. The telemetry terminal converts the dry contact into an active contact through internal circuit conversion. When the tipping bucket of the rain sensor turns over once, the dry contact will be turned on once, and then the internal circuit of the terminal will experience a low-level 0 process. Judging how many times the low-level 0 occurs, it can be considered that several 0.5mm of rain has fallen. [0003] Because the rain telemetry terminal is installed in the wild, the environment is relatively harsh, and the moving parts of the tipping bucket are easily e...

AI Technical Summary

Problems solved by technology

[0003] Because the rain telemetry terminal is installed in the wild, the environment is relatively harsh, and the moving parts of the tipping bucket are easily entangled and stuck by foreign objects such as soil, leaves, etc., and the tipping bucket does not have troubleshooting capabilities, which affects the accuracy of rainfall monitoring.
