Automatic ship cabin capacity calibrating device and method based on cloud service platform

Abstract

The invention discloses an automatic ship cabin capacity calibrating device and method based on a cloud service platform. The device comprises a site calibration device, a controller, a mobile terminal, the cloud service platform and a remote terminal, wherein the site calibration device comprises a pipeline connecting terminal, a manual adjusting valve, a filter, a standard metal tank, a temperature transmitter, a magnetostrictive liquid level meter, a putting-into type liquid level meter, an electromagnetic valve and an electric ball valve. The automatic reading of signals of liquid volume values, temperatures, liquid levels and the like of the standard metal tank, the automatic processing of data and the automatic control over the electromagnetic valve and the electric ball valve are achieved. The verification result can be sent to the cloud service platform and can also be read through an electronic tag of an instrument. The whole verification process can be automatically completed, errors of manual verification are greatly reduced, and the verification efficiency and accuracy are improved.

Description

technical field [0001] The invention belongs to the field of automatic detection technology and wireless communication, and relates to a capacity automatic calibration device and method based on a cloud service platform. Background technique [0002] my country's capacity measurement benchmark was approved and promulgated by the National Bureau of Metrology in 1986. Correspondingly, a verification system is established so that the value of the capacity unit reproduced by the national standard of capacity can be passed to the next level of measurement standard through verification, and then passed to the working measuring instruments step by step to ensure that the tested measuring instrument The values ​​are exactly the same. At present, volumetric working measuring instruments are widely used in trade settlement and liquid storage. The accuracy of capacity measurement directly affects the profit and loss in trade and the quality of products, so it is of great significance...

AI Technical Summary

Problems solved by technology

[0005] 1. When a single metal gauge is calibrated, the water intake and calibration process of the metal gauge cannot be carried out at the same time, and the water intake time of the metal gauge is longer, which makes the calibration efficiency lower;

[0006] 2. The water inlet and outlet of standard metal gauges need to be manually operated, which is labor-intensive. At the same time, the liquid level, temperature and other values ​​of metal gauges need to be read manually, which is easy to introduce human measurement errors;

[0007] 3. When calibrating the inspected cabin, because the volume of the inspected object is different, the calibration device needs to be changed accordingly, and the operation is cumbersome;

[0008] 4. The existing capacity calibration device can only be operated on site, and the data recording is done manually, which is prone to errors and omissions, and the equipment often cannot be remotely calibrated
