Abstract

A method and system for transmitting signals to control a utility service from a drive-by or walk-by control unit includes an electronically controlled shut-off valve in a supply line for the utility service. The shut-off valve has a solenoid that communicates electronically with a meter transceiver used by a metering device. A transmitter is included in the walk-by or drive-by control unit and sends a signal to the wireless transceiver to operate the solenoid to close the valve or to open the valve. After this action occurs, the meter transceiver will send an acknowledge signal to the control unit to confirm that the shut-off valve has been opened or closed.

Claims

1. A system for mobile wireless shut-off of a utility service, the system comprising:

a valve for connection in a supply line supplying the utility service, the valve being connected in advance of a utility metering device;

the valve including an electrically operable actuator for opening and closing the valve in response to electrical signals; and

a transceiver electrically communicating with the electrically operable actuator to open or close the valve in response to receiving wireless control signals from a mobile radio signaling unit.

2. The system as recited in claim 1, wherein the transceiver also receives command signals and transmits electrical metering signals from the utility metering device.

3. The system as recited in claim 2, wherein the valve, the transceiver and the utility metering device are located in a subsurface pit enclosure.

4. The system of claim 2, wherein the utility is water.

5. The system of claim 1, wherein the mobile radio signaling unit is carried by a vehicle or is a carried by a person covering a route for meter data collection.

6. The system of claim 1, wherein the transceiver is part of an assembly that includes a processor, and wherein the processor senses a on or off condition of the valve and transmits an acknowledge signal to the mobile radio signaling unit in response to the opening or closing of the valve.

7. The system as recited in claim 1, wherein the transceiver further comprises:

a CPU operating according a stored control program; and

a radio frequency modulation and demodulation section for transmitting and receiving radio frequency signals and for communicating data and control signals with the CPU.

8. The system as recited in claim 1, wherein the transceiver operates in a frequency range between 902 Mhz and 928 Mhz.

9. The system as recited in claim 1, wherein the transceiver operates through transmission of frequency hopping spread spectrum signals.

10. A method of controlling an on or off condition of a utility service, the method comprising:

using a shut-off valve in a supply line supplying the utility service, the valve being connected in advance of a utility metering device;

providing the valve with an electrically operable actuator for opening and closing the shut-off valve in response to electrical signals;

using a meter transceiver to communicate electronically with the electrically operable actuator to open or close the shut-off valve in response to receiving wireless control signals; and

the meter transceiver receiving wireless control signals from a transceiver in a mobile radio signaling unit, and being responsive to such control signals, to send signals to the electrically operable actuator to open or close the shut-off valve.

11. The method of claim 10, wherein the meter transceiver receives command signals and transmits electrical metering signals from the utility metering device.

12. The method as recited in claim 11, wherein the valve, the transceiver and the utility metering device are located in a subsurface pit enclosure.

13. The method of claim 12, wherein the utility is water.

14. The method of claim 10, wherein the mobile radio signaling unit is carried by a vehicle or is a carried by a person covering a route for meter data collection.

15. The method of claim 10, further comprising transmitting an acknowledge signal to the mobile radio signaling unit in response to the opening or closing of the shut-off valve to confirm an open or closed condition of the shut-off valve.

16. The method as recited in claim 10, wherein the meter transceiver operates in a frequency range between 902 Mhz and 928 Mhz.

17. The method as recited in claim 10, wherein the meter transceiver operates through transmission of frequency hopping spread spectrum signals.
