Mining dump truck oil level measurement device and measurement method

Abstract

The invention discloses a mining dump truck oil level measurement device and a measurement method. The mining dump truck oil level measurement device comprises an inclination angle sensor, a speed sensor, a liquid level sensor, a controller, a liquid crystal display and an engine ECU. Compared with a traditional oil level measurement mode, the angle of the road surface which a dump truck is attached to is measured through the inclination angle sensor, and the oil levels of the dump truck on inclined and ramp road surfaces can be accurately measured. After an engine of the dump truck is started, the speed of the dump truck is judged, the fuel consumption of the dump truck is calculated through the instant fuel consumption of the engine, the fuel oil level of the dump truck in the movement process is obtained by subtracting the fuel consumption of the engine from oil level data measured when the dump truck is static, the influences caused by pitching to the oil level when the dump truck is driven are eliminated, and the fuel oil level is accurately and stably displayed. The oil level measurement precision, especially the oil level measurement precision in the movement process, of the dump truck is improved without increasing cost, and practicability is high.

Description

technical field [0001] The invention relates to a measuring device and a calculation method, in particular to a fuel level measuring device and a measuring method of a mining dump truck, and belongs to the technical field of engineering machinery. technical background [0002] Mining dump trucks are widely used in open-pit mines, large-scale infrastructure construction and other working conditions. Its working terrain is complex, the weather conditions are harsh, continuous work is required, and the fuel consumption is relatively large. If the liquid level measurement error is large, it will appear that the fuel tank will be refueled when there is too much fuel left or when the fuel is exhausted, which will affect the work of the dump truck. Therefore, it is particularly important to accurately measure the liquid level of the dump truck fuel tank. General liquid level measurement methods include: float method, float Hall element sensor, optical fiber sensing technology, ult...

Problems solved by technology

Its working terrain is complex, the weather conditions are harsh, continuous work is required, and the fuel consumption is relatively large. If the liquid level measurement error is large, it will appear that the fuel tank will be refueled when there is too much fuel left or when the fuel is exhausted, which will affect the work of the dump truck. Efficiency, so it is particularly important for accurate measurement of dump truck fuel tank liquid level

General liquid level measurement methods include: float method, float Hall element sensor, optical fiber sensing technology, ultrasonic method, guided wave radar level gauge, differential pressure method, piezoresistive pressure sensor, capacitive pressure sensor, currently domestic liquid There are also many bit measurement technologies and products. These measurement methods have their own advantages and disadvantages, either the measurement accuracy is not high, or the price is relatively expensive.

The disadvantage of the above measurement method is that the premise of accurate measurement is that the liquid level is a plane. Due to the influence of the operating environment of the dump truck, the vibration and swing of the fuel tank are relatively large. The liquid level of the fuel tank is not a stable plane, and the liquid level is affected by the movement of the dump truck. Fluctuates up and down, only when the dump truck is stationary or the operating environment is very stable can a stable liquid level be obtained
