Abstract
A calibration system is configured to detect a capacity difference of a tipping bucket rain gauge and determine an operational condition of the tipping bucket rain gauge. The calibration system includes a field calibration device, a detection communication box, and an application. The application is executed by an electronic device, which, upon receiving metering information and environmental information transmitted by the detection communication box, can calculate the capacity difference of the tipping bucket rain gauge. The calibration system allows an operator to directly perform testing of the capacity difference and the operational condition of the tipping bucket rain gauge, so as to provide users with follow-up measures or suggestions.
Claims6
A calibration system, comprising:
- a field calibration device including:
- a water bottle configured to contain water necessary for simulating rainfall;
- a constant head adaptor installed at an open end of the water bottle, wherein a needle that is replaceable is disposed at an outlet end of the constant head adaptor;
- and
- a placement frame, wherein the placement frame is configured to allow the water bottle that is installed with the constant head adaptor to be invertedly disposed inside a collection funnel of a tipping bucket rain gauge to be tested;
- wherein, when the water bottle is filled with the water, and the water bottle and the constant head adaptor are invertedly disposed inside the collection funnel via the placement frame, the water contained in the water bottle is configured to flow out of the needle through the constant head adaptor at a predetermined flow rate and enter the collection funnel of the tipping bucket rain gauge, so as to simulate a condition where the tipping bucket rain gauge is exposed to the rainfall with a predetermined intensity;
- an application configured to be executed by an electronic device;
- and
- a detection communication box including:
- a measurement sensor module, wherein, when the measurement sensor module detects an automatic tipping action of a plurality of buckets of the tipping bucket rain gauge that are filled with the water up to a nominal volume, the measurement sensor module is configured to correspondingly generate metering information;
- an environmental condition sensor, wherein the environmental condition sensor is configured to sense at least one environmental parameter of a temperature, a humidity, and an atmospheric pressure of an environment where the detection communication box is located, and to correspondingly generate environmental information;
- a message transmission module configured to transmit the metering information and the environmental information to the electronic device that executes the application;
- and
- a power supply module electrically connected to the measurement sensor module, the environmental condition sensor, and the message information transmission module;
- wherein, after the electronic device that executes the application receives the metering information and the environmental information, the application is configured to calculate a capacity difference of the tipping bucket rain gauge according to the metering information, the environmental information, the predetermined flow rate, and the nominal volume of each of the buckets of the tipping bucket rain gauge;
- wherein the application is configured to determine whether or not the capacity difference exceeds an acceptance standard, so as to correspondingly generate a suggestion message.
