Controlling heating and communication in a pipeline system
A method for controlling a pipeline system is provided. The method includes powering on an electrical heating source for heating the pipeline system. The method further includes powering off the electrical heating source, powering at least a sensor along the pipeline system for measuring a physical property, and communicating the measured data to a remote communication destination.
1. A method for controlling a pipeline system comprising a pipeline portion, an electrical heating source distributed along the pipeline portion, and at least one sensor on the pipeline portion for measuring a physical property along the pipeline portion, the sensor comprising a communication device for communicating the measured data to a remote communication destination, the method comprising:
a first act of powering on the electrical heating source for heating the pipeline portion; and
a second act of switching off the electrical heating source, powering on the sensor for measuring a physical property, and communicating the measured data to the communication destination.
2. The method of claim 1 , wherein one of the first act or the second act is executed immediately after the other of the first act or the second act.
3. The method of claim 2 , wherein the electrical heating source and the sensor are periodically powered on, each time period including powering on one of the electrical heating source or the sensor immediately followed by powering on of the other the electrical heating source or the sensor.
4. The method of claim 3 , wherein duration of second act is less than 2% shorter than duration of the first act.
5. The method of claim 2 , wherein the first act and the second act are periodically executed, each time period including an execution of one of the first act or the second act immediately followed by an execution of the other of the first act or the second act.
6. The method of claim 5 , wherein duration of second act is less than 2% shorter than duration of the first act.
7. The method of claim 1 , wherein duration of second act is less than 2% shorter than duration of the first act.
8. The method of claim 1 , wherein duration of second act is less than 1% shorter than duration of the first act.
9. A control system associated to a pipeline system comprising a pipeline portion, an electrical heating source distributed along the pipeline portion, and at least one sensor on the pipeline portion for measuring a physical property along the pipeline portion, the sensor comprising a communication device for communicating the measured data to a remote communication destination, the control system configured to:
power on the electrical heating source for heating the pipeline portion; and
switch off the electrical heating source, power on the sensor for measuring a physical property, and communicate the measured data to the communication destination.
10. The control system of claim 9 , wherein the electrical heating source or the sensor is powered on immediately after the other of the electrical heating source or the sensor is powered on.
