Problems solved by technology
[0004] At present, in the control of hydraulic oil pollution in the hydraulic system, the hydraulic system is mostly equipped with a filter to control the solid particle pollution of the hydraulic oil. Although this method can filter the hydraulic oil to a certain extent and reduce the pollution of the hydraulic oil, there is a problem. The biggest flaw is that there is no specific basis for when the filter needs to be replaced, and there is no predictive analysis of the hydraulic oil pollution situation

Embodiment 1
[0018] Embodiment one: see Figures 1 to 3 As shown, a hydraulic oil pollution degree detection method, when the hydraulic system returns oil, the pressure sensor detects the pressure in the hydraulic pipeline at the front end of the oil filter, and transmits the signal to the central processing unit through the signal amplification module and the A / D conversion module, The light beam emitted by the light-emitting element is incident on the photoelectric sensor through the hydraulic oil. The photoelectric sensor receives the light beam and transmits the signal to the central processing unit through the signal amplification module and the A / D conversion module. The central processing unit receives the signal and processes it to obtain the pollution degree of the hydraulic oil. Through The CAN communication module transmits the pollution degree of the hydraulic oil to the vehicle CAN communication system and displays it on the display device.

The invention discloses a hydraulic oil pollution degree detection method and a hydraulic oil pollution degree detection device. The method is characterized in that: when oil returns to a hydraulic system, a pressure sensor detects the pressure in a hydraulic pipeline at the front end of an oil filter, and transmits signals to a central processing unit (CPU) through a signal amplification module and an analog / digital (A / D) conversion module; a light emitting element emits beams to a photoelectric sensor through hydraulic oil; the photoelectric sensor receives the beams and transmits the signals to the CPU through the signal amplification module and the A / D conversion module; the CPU receives the signals and processes the signals to obtain hydraulic oil pollution degree; and the hydraulic oil pollution degree is transmitted to a whole CAN communication system through a CAN communication module and displayed in a display device. The device can accurately detect the hydraulic oil pollution degree, is convenient to maintain, and reduces the fault caused by the pollution of the hydraulic oil.
Description
technical field [0001] The invention relates to a hydraulic oil detection system, and specifically designs a hydraulic oil pollution degree detection method and device for mining dump trucks. Background technique [0002] With the continuous advancement of science and technology, all kinds of heavy-duty transportation tools have been widely used, such as trucks, dump trucks, etc., among which mining dump trucks are the most widely used. Mining dump truck refers to a non-highway heavy-duty dump truck used in open-pit mines to complete the tasks of rock and earth stripping and ore transportation. It is suitable for various mines and water conservancy projects. Due to the large geometric size and other characteristics, with the development of more and more large-scale open-pit mining areas and the construction of large-scale projects, mining dump trucks have been more used and developed. [0003] Due to the harsh working environment of mining dump trucks, the safety and stabil...
