Abstract
A cable leakage detection system to be placed in a moving vehicle for monitoring signal leakages in a cable television plant whereby an RF detection meter is combined with a global positioning system and a computer control unit to measure radio frequency signal strength, while maintaining the corrected distance between the vehicle and the source of the leak, determine longitude and latitude of the measured signal strength, and store the signal strength, longitude and latitude in data files.
Claims22
A cable leakage monitoring system comprising:
- means for determining the geographic location of said monitoring system;
- means for measuring the signal strength of radio frequency signals;
- means, electrically connected to said determining means and said measuring means, for reading said geographic location from said determining means, and said signal strength from said measuring means, and storing said read geographic location and said strength in a data file;
- and
- a keypad electrically connected to said reading and storing means for sending information to said reading and storing means, wherein said information comprises the distance between said measuring means and a source of said radio frequency signals.
The cable leakage monitoring system located within a moving vehicle for logging geographic location and radio frequency signal strength into a data file comprising:
- a geographic location system for determining the geographic location of said monitoring system;
- a radio frequency detection system for measuring the signal strength of said radio frequency signals;
- a control unit, electrically connected to said geographic location system and to said radio frequency detection system, for reading geographic location information from said location system and signal strength information from said radio frequency detection system, and storing said read information in a data file;
- and
- a keypad, electrically connected to said control unit, for sending information to said control unit, wherein said information that is sent to said control unit comprises the distance between said radio frequency detection system and a source of said radio frequency signals.
The cable leakage monitoring system to be placed in a moving vehicle for reading geographic location information and radio frequency signals strength information, and storing said read information into a delimited text file, the system comprising:
- a global positioning system for determining the longitude and latitude of said monitoring system;
- a radio frequency detection system for measuring the signal strength of said radio frequency signals;
- a control unit, electrically connected to said global positioning system and to said radio frequence detection meter, for reading said longitude and latitude from said global positioning system, and reading said measured signal strength from said radio detection meter, and storing said read information into said text file;
- and
- a keypad, electrically connected to said control unit, for sending information to said control unit, wherein said information that is sent to said control unit comprises:
- flag information for logging broken cables or damaged pedestals, said flag information being stored with said read information in said text file;
- program pause and restart commands for pausing and restarting said reading and said storing of information;
- and
- a program end command for stopping the reading and storing of said information.
The cable leakage monitoring system to be placed in a moving vehicle for reading longitude, latitude and radio frequency signal strength information, and storing said read information into delimited text files for import into a digital mapping system, the system comprising:
- a global positioning system for determining the longitude and latitude of said monitoring system;
- a radio frequency detection system for measuring the signal strength of said radio frequency signals;
- a control unit, electrically connected to said global positioning system and to said radio frequence detection meter, for reading said longitude and latitude from said global positioning system, and reading said measured signal strength from said radio detection meter, and storing said read information into said text file;
- and
- a keypad, electrically connected to said control unit, for transmitting information to said control unit and displaying information received from said control unit, wherein said transmitted information comprises the distance between said radio frequency detection meter and a source of said radio frequency signals and flag information for logging broken cables or damaged pedestals, said flag information being stored with said read information in said text files.
