The object of the present invention is to provide a kind of oil leak monitoring method for gas station's oil machine, realize that oil machine automaticly inspects leakage
Oil and manual inspection oil leak, to prevent petrol station from occurring having good luck not fuel-displaced phenomenon, solve to occur having good luck due to petrol station it is not fuel-displaced and
Oiling client is caused to occur serious discontented.
The present invention provides a kind of oil leak monitoring method for gas station's oil machine comprising：
Predetermined refueling time, predetermined pulse number and flow threshold in predetermined refueling time are previously stored in control system
Value, and when gas station's oil machine is in idle condition to oil machine transmission start refuel order, start simultaneously at statistics refueling time and
First umber of pulse of the encoder output in oil machine is set；
When refueling time reaches predetermined refueling time, control system is to oil machine transmission stopping oiling order and pre- second
The flow value that the second umber of pulse of interior statistical coding device output of fixing time is sent with the flowmeter being arranged in oil machine；
When second umber of pulse is not 0 or first umber of pulse is greater than predetermined pulse number, and work as the flow
Value is judged as oil leak when exceeding flow threshold.
Preferably, in the oil leak monitoring method for gas station's oil machine, when control system interval regulation monitors
Between section carry out oil leak monitoring.
Preferably, in the oil leak monitoring method for gas station's oil machine, lift is detected in oil leak monitoring process
Rifle restarts when acting.
Preferably, in the oil leak monitoring method for gas station's oil machine, when second umber of pulse be 0 or
When first umber of pulse is less than predetermined pulse number, control system sends the order of pressurization to the oil machine.
Preferably, in the oil leak monitoring method for gas station's oil machine, whether control system also detects oil machine
It is in idle condition.
Preferably, in the oil leak monitoring method for gas station's oil machine, control system is also received and is manually sent
The order for opening oil leak monitoring, and detect whether oil machine is in idle condition.
Preferably, in the oil leak monitoring method for gas station's oil machine, control system terminates in oil leak monitoring
When store first umber of pulse, second umber of pulse, the flow value and determine result.
The present invention provides a kind of oil leak monitoring method for gas station's oil machine comprising：It is stored in advance in control system
There are predetermined refueling time, predetermined pulse number and flow threshold in predetermined refueling time, and is in idle shape in gas station's oil machine
Start order of refueling to oil machine transmission when state, starts simultaneously at the of statistics refueling time and the encoder output that is arranged in oil machine
One umber of pulse；When refueling time reaches predetermined refueling time, control system is to oil machine transmission stopping oiling order and pre- second
The flow value that the second umber of pulse of interior statistical coding device output of fixing time is sent with the flowmeter being arranged in oil machine；When described
Two umber of pulses be not 0 or first umber of pulse be greater than predetermined pulse number when, and when the flow value exceed flow threshold when
It is judged as oil leak.The present invention realize oil machine automaticly inspect oil leak and manual inspection oil leak, with prevent petrol station occur having good luck it is not fuel-displaced
The phenomenon that, it solves to occur having good luck due to petrol station not fuel-displaced and oiling client is caused to occur seriously being discontented with.
Further advantage, target and feature of the invention will be partially reflected by the following instructions, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
Detailed description of the invention
Fig. 1 is the flow chart provided by the present invention for one embodiment of the oil leak monitoring method of gas station's oil machine；
Fig. 2 is the flow chart provided by the present invention for another embodiment of the oil leak monitoring method of gas station's oil machine.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or combinations thereof.
As shown in Figure 1, start by set date leaks hunting function when fuel charger is in idle condition for a long time.During starting is leaked hunting,
It is unable to blunderbuss oiling, otherwise directly closes to leak hunting and function and clock again.During function is leaked hunting in starting, sends and refuel to tax control
Initiation command (A1), and time recording encoder output umber of pulse, if in the output pulse of set time inner encoder in effective model
In enclosing, there is no pulse generation in extra time, then it is assumed that be that vacant tubing pressure is inadequate for a long time, suppress for oil pipe；If solid
It is more than effective range that inner encoder of fixing time, which exports pulse, or there are also pulse generations and lasting more stable stream in extra time
Speed (greater than the flow speed value of some setting), then it is assumed that there is interior leakage to generate in oil pipe, after leaking hunting or when formal blunderbuss is refueled,
Early warning maintenance.After leaking hunting then, sending to refuel to tax control terminates (A2), records the successful data that leaks hunting, and close and leak hunting
Function.
As shown in Fig. 2, when fuel charger is in idle condition, it is artificial that function of leaking hunting is started by keyboard.Starting is leaked hunting the phase
Between, it is unable to blunderbuss oiling, is otherwise directly closed and is leaked hunting function and record miss data of leaking hunting.During function is leaked hunting in starting, to
Tax control sends oiling initiation command (A1), and time recording encoder output umber of pulse, if exporting in set time inner encoder
Pulse does not have pulse generation in effective range, in extra time, then it is assumed that is that vacant tubing pressure is inadequate for a long time, is oil pipe
It suppresses；If being more than effective range in the output pulse of set time inner encoder, or generates and continue there are also pulse in extra time
More stable flow velocity (greater than the flow speed value of some setting), then it is assumed that have interior leakage generation in oil pipe, after leaking hunting or just
When formula blunderbuss is refueled, early warning maintenance.After leaking hunting then, sending to refuel to tax control terminates (A2), and record, which leaks hunting, successfully to be counted
According to exiting closing by keyboard and leak hunting function.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and legend shown and described herein.
