Abstract
A valve control apparatus including: an operating time measurement unit that measures an operating time of a valve based on an operation pressure of the valve and whether the valve is open or closed; and a command control unit that receives an opening command directed to the valve and transmitted from a control apparatus, and transmits the opening command to the valve in a delayed manner based on the operating time and a predetermined reference time.
Claims10
A valve control apparatus comprising:
- an operating time measurement unit configured to:
- receive from a pressure sensor an operation pressure being applied to a valve and receive from an opening and closing sensor a detection of whether the valve is open or closed, and
- measure an operating time of the valve, as a measured operating time that is based on a combination of the operation pressure of the valve and the detection of whether the valve is open or closed;
- a delay time determination unit configured to determine a delay time, based on a combination of the measured operating time and a predetermined reference time;
- and
- a command control unit configured to receive an opening command that is directed to an opening/closing operation of the valve and is transmitted from a control apparatus, and, in response, to transmit the opening command to the valve at a transmit time that is delayed, by the delay time, from a time at which the command control unit receives the opening command,
- wherein the predetermined reference time is a stored value of a reference amount of time that extends between an application of pressure to the valve and a corresponding opening operation of the valve.

A valve control method comprising:
- an operating time measurement step, including:
- receiving from a pressure sensor a measured operation pressure applied to a valve,
- receiving from an opening and closing sensor a detection of whether the valve is open or closed, and
- measuring an operating time of the valve, as a measured operating time, based on the measured operation pressure applied to the valve and the detection of whether the valve is open or closed;
- a step of determining a delay time, based on a combination of the measured operating time and a predetermined reference time;
- and
- an opening command control step of receiving, from a control apparatus, an opening command that is directed to an opening/closing operation of the valve and, in response, transmitting the opening command to the valve in a delayed manner based on the operating time and a predetermined reference time,
- wherein the predetermined reference time is a stored value of a reference amount of time that extends between an application of pressure to the valve and a corresponding opening operation of the valve.
5 more elements
A valve control program for causing a computer to execute:
- an operating time measurement command to:
- receive from a pressure sensor an operation pressure applied to a valve and receive from an opening and closing sensor a detection of whether the valve is open or closed, and
- measure an operating time of the valve, as a measured operating time, wherein the measured operating time is based on a combination of the operation pressure of the valve and the detection of whether the valve is open or closed;
- a delay time determination command to determine a delay time based on a combination of the measured operating time and a predetermined reference time;
- and
- an opening control command to receive, from a control apparatus, an opening command that is directed to an opening/closing operation of the valve and, in response, to transmit the opening command to the valve at a transmit time that is delayed, by the delay time, from a time at which the command control unit receives the opening command,
- wherein the predetermined reference time is a stored value of a reference amount of time that extends between an application of pressure to the valve and a corresponding opening operation of the valve.
4 more elements
A valve control system, comprising:
- a valve;
- a control apparatus that is configured to transmit an opening command that is directed to an opening/closing operation of the valve;
- a valve control apparatus that is configured to adjust, as an operating time, time from a predetermined time point at which operation pressure changes to a predetermined time point at which operation corresponding to the change is detected, the operation pressure being applied to the valve, wherein
- the valve includes:
- an operation pressure sensor that is configured to measure the operation pressure applied to the valve and output, in response, a measured operation pressure applied to the valve;
- and
- an opening and closing sensor that is configured to detect at least whether the valve is open or closed and output, in response, a detection of whether the valve is open or closed, and
- the valve control apparatus includes:
- an operating time measurement unit that is configured to:
- receive from the pressure sensor the measured operation pressure applied to the valve, and
- measure the operating time, as a measured operating time, based on the measured operation pressure applied to the valve and the detection of whether the valve is open or closed;
- a delay time determination unit that is configured to determine a delay time based on a combination of the measured operating time and a predetermined reference time, wherein the predetermined reference time is a stored value of a reference amount of time that extends between an application of pressure to the valve and a corresponding opening operation of the valve;
- and
- a command control unit that is configured to receive, from the control apparatus, the opening command that is directed to the opening/closing operation of the valve and, in response, to transmit the opening command to the valve at a transmit time that is in a delayed, by the delay time, from a time at which the command control unit received the opening command.
