Abstract

The invention discloses a water sensor verification platform and method, and the method comprises the steps: setting an installation plate which can hold various types of water sensors at the same time in a water tank, automatically supplying water to a preset early-warning water level through a water supply and drainage system, enabling a timing module to start timing after receiving a signal indicating that water reaches a preset warning level; after the response signals are received, timing is stopped, so that the response time of the multiple to-be-detected water sensors is obtained, the response time is compared with the preset standard response time, the response time and the sensitivity can be verified, meanwhile, the sensor signal values of the to-be-tested water sensors are compared with the standard sensor signal values, so that the error value of the sensor signal values can be obtained, the sensor signal value can be verified, the purpose of verifying the water sensors to be tested in batches at the same time is achieved, the labor intensity of workers is reduced, and the verification error is reduced.

Description

technical field [0001] The present application relates to the technical field of instrument calibration, in particular to a water immersion sensor calibration platform and a calibration method using the platform. Background technique [0002] The water immersion sensor is one of the important industrial equipment currently used in the field of intelligence. It is widely used in data centers, communication rooms, substations, warehouses, archives and other places that require waterproofing. Once water leakage occurs, the sensor can immediately send out an alarm signal, and take effective measures in time to avoid heavy losses and hazards. Therefore, the calibration of water immersion sensors is particularly important, and it is imperative to build a calibration platform for water immersion sensors. [0003] There are various forms of water immersion sensors on the market, and their structures are also different, such as electrode type water immersion sensors, photoelectric w...
