Problems solved by technology
However, in all methods, there is a real problem. When the locomotive is in various working conditions, both the pressure and the liquid level will change instantaneously with the working conditions of the locomotive, so there are peaks in the acquired sampling signal waveform, and there is no rules to follow

Embodiment 1
[0040] The present invention will be described in detail below in conjunction with the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0041] First, take points at two symmetrical positions A and A' of the locomotive oil tank about the geometric center of the locomotive oil tank, as shown in Figure 8 and Figure 9, and then measure the oil pressure data at points A and A' through two sets of oil measuring devices , the method used is: lead the oil out from A and A' respectively, and then pass through the shunt pipe to buffer a part of the impact energy of the fuel, and then enter the sampling oil column through the small hole oil pipe, and finally measure the pressure at the bottom of the sampling oil column through the pressure sensor data, and then convert the pressure data into oil volume data.
[0042] The specific structure of each group of oil measuring devices is as follows:
[0043]The oil inside the locomotive oil tank enter...

The invention discloses a method for measuring oil in a locomotive oil tank and a device thereof. The method comprises the following steps: measuring the oil mass data of any two points which are close to a boundary point in the locomotive oil tank and symmetrical with the geometrical central of the locomotive oil tank as the symmetrical center, and averaging the two oil mass data to obtain a current oil mass result of the locomotive oil tank. Fuel oil extracted from each boundary point is shunted by a shunt pipe and then buffered by a pore oil pipe to enter a sampling oil column; and the bottom of the sampling oil column is provided with a pressure sensor to measure the oil mass data at the boundary point. The invention can effectively buffer fluctuation due to oil fluid level and pressure of the locomotive oil tank under different working conditions, so as to obtain accurate oil mass measuring results.
Description
technical field [0001] The invention belongs to the field of mechanical and electronic engineering, and relates to a method and a device for measuring oil in a fuel tank of a locomotive by using a ruler. Background technique [0002] In the existing technology, the methods for obtaining the remaining fuel volume of the locomotive fuel tank include (1) estimating the remaining fuel volume by obtaining the pressure signal at the bottom of the fuel tank; (2) estimating the remaining fuel volume by obtaining the fuel tank liquid level signal by using a buoy. However, in all methods, there is a real problem. When the locomotive is in various working conditions, both the pressure and the liquid level will change instantaneously with the working conditions of the locomotive, so there are peaks in the acquired sampling signal waveform, and there is no There are rules to follow. Therefore, in terms of technical realization, we need to consider a mechanical structure that can buffer ...
