Abstract

The invention discloses a test method for a ship's liquid level sensor based on Labview, which includes building a test system, system initialization, setting test items and sensor information to be tested, testing and data processing. The invention has the advantages of automatic testing process, the shortest test time for a single item, greatly improving production efficiency to meet the requirements of mass production; it can adapt to different types of sensors and reduce repeated development work; the test has high precision and good repeatability. Minimize the influence of human factors; use a database to record test data and increase product traceability.

Description

technical field [0001] The invention relates to a testing method, in particular to a testing method for a liquid level sensor. Background technique [0002] Liquid level sensor is an important part of the transportation monitoring system, and its product quality is very important. The rapid development of the shipbuilding industry has put forward higher requirements for the testing of liquid level sensors. Classification societies require that liquid level sensors must pass performance tests before leaving the factory. In the original liquid level sensor test, manual measurement, manual calibration, and manual recording are usually used for operation. Not only is the test efficiency low and error-prone, but also the communication with the liquid level sensor cannot be realized, which is not conducive to product traceability. manage. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to prov...
