Example Embodiment

[0013] The invention will be further described below with reference to the drawings and embodiments, but the invention is not limited to the scope of the embodiments.

[0014] Refer to figure 1 . In the embodiments described below, the automatic refueling and draining detection electrical detection device mainly includes a refueling and draining stand and a measurement console, and the measurement console is connected to a corresponding cable socket on the refueling and draining stand through a dedicated test cable. The measurement console includes an oil level measurement unit, an oil level control unit, a fault self-diagnosis system, and a power control unit which are respectively cross-linked to the integrated control processing system (mainly refers to the industrial control computer). The refueling and discharging stand contains a refueling solenoid valve 6 and a fuel discharging solenoid valve 10 that control the fuel flow to close the fuel flow, a standard liquid level mea...

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...
