After a user sends an instruction for opening the valve to the electronic equipment, the electronic equipment acquires a first pressure value of the pipeline at the moment, judges whether the first pressure value is larger than a first pressure threshold value, if so, acquires a first valve opening corresponding to the first pressure threshold value, controls the valve to be changed from closed to open, and controls the opening of the valve to gradually increase to the first valve opening. If the first pressure value is smaller than or equal to the first pressure threshold value, the electronic equipment judges whether the first pressure value is smaller than the second pressure threshold value or not; if the first pressure value is less than the second pressure threshold, the electronics control the opening of the valve and the opening increases to a maximum, i.e. the valve is fully open, and then gradually decreases to a specified opening.
Specifically, when the first pressure value is greater than the first pressure threshold value, the pressure in the pipeline is high at the moment, so that the use requirement of the gas consumption equipment is met, the valve is gradually opened, and the pressure in the pipeline and the opening of the valve are preset and correspond to each other. The specified opening degree is the same as the case where the control valve is reduced to the specified opening degree because of the opening degree size set in advance.
As an optional implementation manner of the embodiment of the application, after the valve is opened, the method further comprises the steps of obtaining a current pressure value of the pipeline and judging whether the pipeline belongs to a concentrated consumption period or not based on the current pressure value; if the time belongs to the concentrated consumption period, acquiring the current time, and judging whether the time belongs to the concentrated consumption period or not based on the current time; if the concentrated consumption period exists, acquiring a second valve opening corresponding to the current pressure value, and controlling the opening of the valve to be increased to the second valve opening; if the period does not belong to the concentrated consumption period, the valve does not act.
After the valve is opened, the current pressure value of the pipeline is obtained, whether the pipeline is in a concentrated consumption period is judged based on the current pressure value, the concentrated consumption period is the condition that a plurality of or all gas consumption devices work, the pressure in the pipeline can be reduced rapidly, if the pipeline belongs to the concentrated consumption period, the current time is obtained, whether the pipeline is in the concentrated consumption period is judged based on the current time, namely, whether the current time is the time for simultaneously working a plurality of gas consumption devices is judged, if the pipeline is in the concentrated consumption period, the second valve opening corresponding to the current pressure value is obtained, and the opening of the valve is controlled by the electronic device to be increased to the second valve opening. If the current time does not belong to the concentrated consumption period, the valve does not act.
And at the moment, the electronic equipment can control the related alarm device to alarm, so that a prompting effect is achieved, and at the moment, the pressure abnormality occurs.
Specifically, judging whether the pipeline pressure belongs to the concentrated consumption period includes: acquiring a historical pressure value; calculating a pressure difference value between the current pressure value and the historical pressure value; if the pressure difference is greater than the third pressure threshold, the pipeline pressure belongs to the concentrated consumption period; the historical pressure value is a pipeline pressure value before the preset time of the current pressure value.
How to judge whether the pipeline pressure belongs to the concentrated consumption period, firstly acquiring a historical pressure value, wherein the historical pressure value is the pressure value in the pipeline when the pipeline is in the concentrated consumption period before the historical pressure value, calculating the pressure difference value between the current pressure value and the historical pressure value, and judging that the pipeline pressure at the moment belongs to the concentrated consumption period if the pressure difference value is larger than a third pressure threshold value, namely the condition that the current pressure value suddenly drops relative to the historical pressure value. Wherein the preset time can be set manually.
As an optional implementation manner of the embodiment of the present application, before the opening degree of the control valve is increased to the second valve opening degree, the method further includes: acquiring gas usage data of a gas consuming apparatus; acquiring a corresponding pressure change value based on the gas usage data; comparing the pressure change value with the pressure difference value; if the pressure change value is smaller than the pressure difference value and the first difference value between the pressure difference value and the pressure change value is larger than the fourth pressure threshold value, the control valve is closed, and an alarm signal is sent to the upper computer to prompt a user.
Before the opening of the electronic equipment control valve is increased to the second valve opening, the electronic equipment acquires gas use data of the gas consumption equipment, acquires corresponding pressure change values based on the gas use data, compares the pressure change values with the pressure difference values, judges whether a first difference value of the pressure difference values and the pressure change values is larger than a fourth pressure threshold value or not if the pressure change values are smaller than the pressure difference values, and controls the valve to be closed and sends an alarm signal to an upper position to prompt a user if the first difference value is larger than the fourth pressure threshold value, namely judges that leakage occurs at the moment. Since the pressure change in the pipeline caused by the gas consumption equipment is smaller than the suddenly-reduced pressure value in the pipeline at the moment, namely the gas reduction amount in the pipeline is larger than the consumption amount of the gas consumption equipment at the moment, the pipeline can be judged to leak at the moment.
As an optional implementation manner of the embodiment of the present application, obtaining a second valve opening corresponding to the current pressure value, and controlling the opening of the valve to increase to the second valve opening, further includes: correcting the second valve opening based on the preset opening to obtain a third valve opening; updating the second valve opening to a third valve opening; the third valve opening is greater than the second valve opening.
When the opening of the control valve is increased to the second valve opening, the second valve opening is corrected based on the preset opening, after correction, the second valve opening is the third valve opening, and the third valve opening is larger than the second valve opening, namely, the opening of the control valve is required to be increased by the preset opening after the control valve reaches the second valve opening, and the corrected value larger than the second valve opening is assigned to the second valve opening. Because the gas storage tank is judged to be in the concentrated consumption period at this time, the output quantity of the gas in the gas storage tank is increased again, and further the gas use requirement is better met.
As an alternative implementation of the embodiment of the present application, after the opening degree of the control valve is increased to the second valve opening degree, the method further includes: acquiring the residual quantity of the gas in the gas storage tank; judging the times that the residual quantity of the gas can meet the concentrated consumption period; if the gas remaining amount satisfies the times less than twice, an alarm signal is sent to the upper computer to prompt the user that the gas remaining amount is low.
After the opening of the control valve is increased to the second valve opening, the electronic equipment acquires the gas consumption corresponding to the concentrated consumption period, and simultaneously acquires the gas residual quantity of the gas storage tank, and judges the number of times that the gas residual quantity can meet the concentrated consumption period, namely, calculates the gas residual quantity to be several times of the gas consumption quantity in the gas consumption period. If the gas residual quantity can meet the requirement for at least two times, the electronic equipment does not act, and if the gas residual quantity can meet the requirement for less than two times, the electronic equipment sends an alarm signal to the upper computer, so that a user is prompted that the gas residual quantity is low, and the gas storage tank needs to be supplemented with gas.
As an alternative implementation of the embodiment of the present application, after the valve is opened, the method further includes: acquiring a second pressure value in the air storage tank; judging whether the second pressure value is smaller than the lower limit value; if yes, the vaporization furnace is controlled to work, and meanwhile, the booster pump is started.
After the valve is opened, the electronic equipment acquires a second pressure value in the air storage tank, judges whether the second pressure value is smaller than a lower limit value, and if the second pressure value is smaller than the lower limit value, the electronic equipment controls the gasification furnace to work, and meanwhile, the electronic equipment controls the booster pump to work. The pressure in the air storage tank is low at the moment, and the situation that the liquid gas vaporization process is not smooth possibly exists, so that the vaporization path is controlled to work at the moment, the vaporization process is accelerated, and the booster pump is utilized to increase the pressure, so that better air supply is ensured.
