Abstract
A system where a sensor is placed in proximity to the nozzle of a hose to monitor pressure or other quantity. The system includes a communication link between the sensor and a remote station. Normally this is a radio link. Pressure values can be transmitted to a receiver and optional processor located near a pump. An operator can then adjust the pump to produce the desired pressure at the nozzle. Optionally, the processor can directly control the pump through a closed-loop feedback system. The communications link can use frequency or space diversity to combat fading. Radio diversity can be accomplished through the use of two or more channels. Any type of sensor can be mounted at the nozzle location.
Claims21
A system for remotely monitoring the pressure at a hose nozzle comprising:
- a pump providing liquid pressure to a nozzle;
- a pressure sensor in proximity to said nozzle monitoring pressure at said nozzle;
- a transmitter coupled to said pressure sensor transmitting messages pertaining to said pressure;
- a receiver receiving said messages from said transmitter and reporting said pressure.
A method of maintaining correct pressure at the nozzle end of a hose comprising the steps of:
- providing a pressure sensor in proximity to said nozzle;
- providing a means for communication from said nozzle to a remote location;
- transmitting current pressure values over said means of communication to said remote location;
- using said pressure values at said remote location to maintain a correct pressure at said nozzle.
A fire hose water pressure monitoring system for monitoring and controlling water pressure at a fire hose nozzle comprising, in combination:
- a pressure sensor for measuring said water pressure, said pressure sensor located near said nozzle;
- a radio transmitter coupled to said pressure sensor for transmitting a signal representative of a pressure value to a remote location;
- at least one radio receiver remote from said nozzle for receiving a transmission from said radio transmitter, said receiver receiving said signal representative of said pressure value;
- a processor in electrical communication with said receiver, said processor presenting said pressure value so that pressure can be controlled.
The system of 17 wherein said processor controls said pressure in a closed loop configuration.
