Abstract
A test point monitor is disclosed which includes, a processor, a cellular modem interfaced to the processor, and at least one analog sensor interfaced to the processor. The monitor is configured with a wake-up cycle, and further configured to periodically measure a voltage during the wake-up cycle utilizing the sensor, and further configured to transmit the measured voltage over a cellular control channel utilizing the modem.
Claims35
A test point monitor configured to monitor operation of corrosion mitigation devices, said monitor comprising:
- a processor;
- a cellular modem interfaced to said processor;
- and
- at least one analog sensor interfaced to said processor, said monitor configured with a wake-up cycle, said monitor configured to periodically measure a voltage utilizing said sensor during the wake up cycle, said monitor further configured to transmit the measured voltage over a cellular control channel utilizing said modem.
A method for measuring voltage potential at underground pipeline test points using a test point monitor, the monitor including at least one analog sensor electrically connected across a pipeline test point and a reference point, said method comprising:
- instructing the monitor to measure at least one voltage potential;
- measuring the voltage potentials;
- and
- providing the voltage potential measurements to an external system.
A test point monitor configured for the measurement of voltages present at a test point of an underground pipeline, said monitor comprising:
- a processor;
- a real-time clock interfaced to said processor;
- a cellular modem interfaced to said processor;
- and
- at least one analog sensor interfaced to said processor, said sensor electrically connected across the test point and a reference point, said processor configured to initiate the voltage measurements upon receipt of a command.
