GPS Modem RF Transmitter Disable for Perforation Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for disabling RF signal transmissions from GPS modems in proximity to down-hole perforation operations either completely shut down the modem, preventing the collection of operational parameters or do not ensure safety by allowing premature detonation of perforation devices due to accidental RF interference.
Innovation Solution
An apparatus and method that allows for the manual disabling of RF signal transmissions from GPS modems, enabling them to resume transmission after a safe distance is traveled away from perforation operations, while continuing to collect and store operational parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the GPS modem is completely shut down to prevent RF signal transmissions, then safety is improved by preventing premature detonation of perforation devices, but the ability to monitor and collect operational parameters is lost
Solution Approach 1:
The patent divides the GPS modem into two independent functional segments: the RF transmitter and the data collection/monitoring system. By selectively disabling only the RF transmitter through a control signal while keeping the data collection functionality operational, the system prevents harmful RF emissions that could trigger perforation devices while maintaining the ability to monitor and record vehicle operational parameters such as location, speed, and operational status.
2Loss of information
If the GPS modem continues to transmit RF signals to maintain monitoring capability, then operational parameter collection is maintained, but the risk of premature detonation of perforation devices increases
Solution Approach 1:
The patent extracts and isolates the RF transmitter function from the rest of the GPS modem system. By applying an external control signal that specifically targets and disables the RF transmitter component, the system removes the harmful RF emission capability while preserving the core data collection and monitoring functions. This extraction allows the modem to operate in a safe mode where only non-RF functions are active in proximity to perforation operations.
3Reliability
If a manual shutdown function is implemented to disable RF transmissions, then safety is improved, but the total shutdown of the modem prevents continued monitoring of vehicle parameters
Solution Approach 1:
The patent implements a dynamic control mechanism that allows the GPS modem to transition between different operational states based on external control signals. The system can dynamically switch between full operation mode (both RF transmission and data collection active), safe mode (only data collection active with RF disabled), and shutdown mode (all functions inactive). This dynamic capability enables flexible operation where the modem adapts its functionality based on proximity to hazardous operations while maintaining monitoring capabilities throughout.

AI summary
An apparatus and method is provided for disabling radio frequency signal transmissions from a wireless communications network modem when in proximity to sites where explosive devices are being detonated. The apparatus includes an input switch to signal a command to the modem to disable the transmitter portion of the modem or to tune the transmitter to a null gateway on the wireless communications network. By disabling transmissions from the modem, accidental detonation of explosive devices is prevented. When the modem is moved a safe distance away from the explosive devices, the transmitter is re-enabled automatically.
