Problems solved by technology

At present, when major shipyards test and submit a large number of various temperature, pressure, and liquid level sensors on board, they use the equipment itself to calibrate one by one on board. Not only is the working environment for workers poor, but also the data measured by the sensors It is also manually recorded and calculated one by one, which has low efficiency and long cycle, which seriously affects the shipbuilding cycle and is not conducive to the development of modern shipbuilding technology for final assembly

Abstract

A comprehensive test-bed comprises a computer which is connected with a pressure check meter and a temperature checking groove through the serial / parallel port of a multi-serial card and connected with a PLC controller through a data line. The PLC controller comprises a digital quantity input module, a current analog input module, a thermo-electric couple input module, a thermal resistor input module and a controller, checks a pressure transmitter, a level transducer, a thermo-electric couple sensor, a thermal resistor sensor, an switching value pressure sensor and an switching value temperature sensor and checks out the plural sensors in batch with high checking efficiency and good operation environment.

Description

Technical field: [0001] The invention relates to a test bench capable of calibrating various sensors used on ships. Background technique: [0002] There are a large number of temperature, pressure and liquid level sensors on the ship. These sensors control or monitor the ship's equipment. They are extremely critical to ensure the normal operation of each device on the ship, and the accuracy requirements are strict. To ensure its accuracy, each sensor needs to be calibrated before installation. At present, when major shipyards test and submit a large number of various temperature, pressure, and liquid level sensors on board, they use the equipment itself to calibrate one by one on board. Not only is the working environment for workers poor, but also the data measured by the sensors It is also manually recorded and calculated one by one, which has low efficiency and long cycle, which seriously affects the shipbuilding cycle and is not conducive to the development of modern sh...
