EXAMPLE III
Fig. 4 is a flowchart of an underwater hydraulic oil control method according to a third embodiment of the present invention, and referring to fig. 4, the method is executed by an underwater hydraulic oil control device according to any one of the embodiments, and specifically includes the following steps:
step 110, the particle detection module detects particles in the hydraulic oil flowing through the hydraulic oil input pipeline and generates a particle detection signal.
Specifically, the particle detection module can irradiate the hydraulic oil in the hydraulic oil input pipeline through the laser light source of the particle detection module, and project the hydraulic oil to the photoelectric conversion unit of the particle detection module to generate a particle detection signal. The particle detection signal can be a voltage signal, for example, pure hydraulic oil enables the particle detection module to generate a flat and straight voltage signal, if the hydraulic oil contains particle pollutants, the projection of the hydraulic oil on the photoelectric conversion unit reduces the light energy, the voltage signal generated by the particle detection module fluctuates, the frequency of the wave reflects the number of particles, and the amplitude of the wave reflects the equivalent diameter of the particles.
Step 120, the monitoring control module adjusts the output selection control signal according to the received particle detection signal.
For example, if the particle detection signal received by the monitoring control module is a flat voltage signal, which indicates that the hydraulic oil flowing through the hydraulic oil input pipeline is pure hydraulic oil, i.e., no particles are in the hydraulic oil, the output selection control signal is adjusted to be a high level, and if the particle detection signal received by the monitoring control module is a fluctuating voltage signal, which indicates that particles are in the hydraulic oil flowing through the hydraulic oil input pipeline, the output selection control signal is adjusted to be a low level, so that the purpose of adjusting the output selection control signal is achieved by adjusting the level.
And step 130, selecting a hydraulic oil transmission pipeline communicated between the hydraulic oil input pipeline and the hydraulic oil output pipeline by the selection control module according to the received selection control signal, so that the hydraulic oil input pipeline is directly communicated with the hydraulic oil output pipeline or the hydraulic oil input pipeline is communicated with the hydraulic oil output pipeline through a filter pipeline.
Specifically, if the selection control signal received by the selection control module is a high level signal, the hydraulic oil flowing through the hydraulic oil input pipeline is pure hydraulic oil, a hydraulic oil transmission pipeline directly communicated between the hydraulic oil input pipeline and the hydraulic oil output pipeline is selected, if the selection control signal received by the selection control module is a low level signal, particles exist in the hydraulic oil flowing through the hydraulic oil input pipeline at the moment, the hydraulic oil input pipeline is selected to be communicated with the hydraulic oil output pipeline through a filtering pipeline, so that the hydraulic oil is filtered through the filtering pipeline, and therefore the pure hydraulic oil is obtained.
For example, the selection control module may control the first electronic control valve to open and the second electronic control valve to close when determining that the setting parameter of the particles in the hydraulic oil flowing through the hydraulic oil input pipeline is less than or equal to the threshold setting parameter according to the received selection control signal. If the selection control module determines that the setting parameter of the particles in the hydraulic oil flowing through the hydraulic oil input pipeline is smaller than or equal to the threshold setting parameter, the particles in the hydraulic oil are few, the purity of the hydraulic oil is qualified, and the hydraulic oil does not need to be filtered, at the moment, the selection control module can control the first electric control valve to be opened and control the second electric control valve to be closed, so that the hydraulic oil is directly transmitted to the hydraulic oil output pipeline through the first hydraulic oil transmission pipeline provided with the first electric control valve. And when the selection control module judges that the setting parameter of the particles in the hydraulic oil flowing through the hydraulic oil input pipeline is greater than the threshold setting parameter according to the received selection control signal, the first electric control valve is controlled to be closed, and the second electric control valve is controlled to be opened. If the selection control module judges that the set parameter of the particles in the hydraulic oil flowing through the hydraulic oil input pipeline is larger than the threshold set parameter, the particles in the hydraulic oil are more, the purity of the hydraulic oil is unqualified, and the hydraulic oil needs to be filtered, at the moment, the selection control module can control the first electric control valve to be closed and control the second electric control valve to be opened, so that the hydraulic oil passes through a second hydraulic oil transmission pipeline provided with the second electric control valve and a filter and is transmitted to a hydraulic oil output pipeline after being filtered by the filter, and the hydraulic oil output pipeline outputs the purer hydraulic oil.
The underwater hydraulic oil control method provided by the embodiment has the corresponding beneficial effects of the underwater hydraulic oil control device.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
