Drawings
FIG. 1 is a flow chart of one embodiment of a method for monitoring oil leakage of a gasoline station engine provided by the present invention;
fig. 2 is a flowchart of another embodiment of the method for monitoring oil leakage of the oil filling station provided by the invention.
Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1, when the fuel dispenser is in an idle state for a long time, the leakage detection function is started regularly. During the starting of the leak detection, the gun cannot be lifted to be oiled, otherwise, the leak detection function is directly closed and timing is recorded again. During the period of starting the leak detection function, sending an oiling start command (A1) to the tax control, and regularly recording the output pulse number of the encoder, if the output pulse of the encoder is in an effective range within fixed time and no pulse is generated in extra time, considering that the pressure of the empty oil pipe is not enough for a long time, and pressing the oil pipe; if the output pulse of the encoder exceeds the effective range within a fixed time, or the pulse is generated and the continuous stable flow rate (greater than a certain set flow rate value) exists within an extra time, the oil pipe is considered to have internal leakage, and the early warning prompts maintenance after the leakage detection is finished or when the gun is formally lifted to be oiled. And after the leakage is detected, sending the end of refueling to the tax control (A2), recording the data of successful leakage detection, and closing the leakage detection function.
As shown in fig. 2, the leak detection function is manually activated via the keyboard when the fuel dispenser is in an idle state. And during the starting of the leak detection, the gun cannot be lifted to be oiled, otherwise, the leak detection function is directly closed and leak detection failure data is recorded. During the period of starting the leak detection function, sending an oiling start command (A1) to the tax control, and regularly recording the output pulse number of the encoder, if the output pulse of the encoder is in an effective range within fixed time and no pulse is generated in extra time, considering that the pressure of the empty oil pipe is not enough for a long time, and pressing the oil pipe; if the output pulse of the encoder exceeds the effective range within a fixed time, or the pulse is generated and the continuous stable flow rate (greater than a certain set flow rate value) exists within an extra time, the oil pipe is considered to have internal leakage, and the early warning prompts maintenance after the leakage detection is finished or when the gun is formally lifted to be oiled.
