The present invention relates to an automatic inspection conduction-type weight-based precipitation gauge and a method for automatically inspecting a precipitation gauge and, more specifically, to an automatic inspection conduction-type weight-based precipitation gauge and a method for automatically inspecting a precipitation gauge, the precipitation gauge storing inspection details in a zero-adjustment state and removing an automatic inspection weight from a current value during an automatic inspection period, so as to compare the current value with a prestored value of the automatic inspection weight, thereby generating a normal operation signal when the compared values are the same and generating an inspection demand signal when the compared values are different. In the automatic inspection conduction-type weight-based precipitation gauge, of the present invention, comprising: a water collection container for collecting precipitation; a flow velocity mitigating hole provided on the lower part of the water collection container so as to mitigate the flow velocity of falling water; a conduction cup inclined toward one side around a rotary axis by the weight of water falling from the flow velocity mitigating hole; a drain for draining stagnant water in the conduction cup; a control unit for receiving a precipitation supply control signal from the outside so as to output a solenoid valve driving signal; a solenoid valve provided on a drain pipe for supplying precipitation so as to temporarily supply precipitation test water by means of the control of the control unit; a data logger for receiving a measured rainfall value from the control unit, and transmitting the precipitation supply control signal to the control unit; and a precipitation measurement management server connected to the data logger so as to confirm a rainfall value received from the data logger, generating a precipitation supply inspection command for periodically inspecting a precipitation gauge so as to transmit the precipitation supply inspection command to the data logger, and receiving a response signal for inspecting the precipitation gauge, received from the data logger, so as to process and display whether there is a malfunction of the precipitation gauge, the automatic inspection conduction-type weight-based precipitation gauge comprises: a load cell in which a lower frame having the conduction cup provided therein is fixedly provided on an upper part thereof; a fixing bracket fixed to one side on which the load cell is provided in a base; a shaft rod coupled to the upper side of the fixing bracket by a hinge pin; an automatic inspection weight provided on one side of the shaft rod so as to be positioned on the upper part of the load cell by being connected by a thread; and a solenoid in which the other side of the shaft rod and the upper side of an operation rod are connected, wherein the solenoid is fixed to the base and is connected to the control unit. |
