Automatic detection equipment for fuel oil measurement system

Abstract

The invention provides automatic detection equipment of a fuel oil measuring system. The automatic oil charging and draining detection equipment is accurate and reliable in measuring and outputting signals, simple and convenient to operate, high in universality, wide in test environment adaptability, and capable of automatically adjusting the oil level to ascend and descend and the speed. According to the technical scheme, a measuring console is electrically connected with a measured signal device circuit through a comprehensive control processing system and is electrically connected with a measured signal device through the measured signal device circuit, an oil level measuring unit is connected with a standard liquid level measuring instrument through a communication module to measure the height of the liquid level in a simulation oil tank, test data are fed back to the comprehensive control processing system in real time, immediate test data are compared with a preset oil level height value, an oil level control unit is used for controlling a relay driver module to drive an oil charging electromagnetic valve and an oil releasing electromagnetic valve to automatically adjust the oil levels to ascend and descend and the speeds in the corresponding simulation oil tanks, and test results after error detection are displayed on a control display table screen.

Description

technical field [0001] The invention relates to an automatic detection device for verifying whether the data collection, processing and measurement accuracy of an aviation fuel measuring system meet the technical index requirements of the aircraft system, and simulating the actual use of the aviation fuel measuring system for comprehensive supporting tests. Background technique [0002] At present, the fuel filling and discharging system testing equipment for the verification test of the aircraft fuel measurement system adopts the test method of manually adding and discharging fuel to the capacitive fuel quantity sensor or fuel level signal, and visually observing the scale to determine the oil level. The disadvantage of this method is that human factors have a great influence, which affects the test accuracy of the fuel oil measurement and control system, and the test efficiency is low. In particular, it simulates the high and low temperature environment filling and drainin...

Problems solved by technology

The disadvantage of this method is that human factors have a great influence, which affects the test accuracy of the fuel oil measurement control system, and the test efficiency is low

In particular, it simulates the high and low temperature environment filling and draining test, and requires the low temperature environment temperature to be -55°C, the high temperature environment temperature to be 70°C, and the fuel flash point to be 38°C. In high temperature environments, manual operation has always had great potential safety hazards.
