Abstract

An equipment controller includes an actuator control module configured for connection to an actuator that provides operational control of a piece of monitored equipment; a sensing module configured to monitor a state of a parameter of the monitored equipment; an optional local control interface for the actuator control module and the sensing module; and a secondary power system to provide operational power for the actuator control modules, the sensing modules and the control interface when primary power to the equipment controller is not available. Where desired, a communications interface to permit communications with a remote operations center may be included. Some or all of the modules may be contained in water tight housings, permitting operation of the equipment controller even when fully submerged in water.

Claims

1. An equipment controller, comprising:

one or more actuator control modules, each configured for connection to an actuator which provides operational control of a respective piece of monitored equipment;

one or more sensing modules, each configured to monitor a state of a parameter associated with each piece of monitored equipment;

a control interface communicatively coupled and configured to permit local operator control of the actuator control modules and the sensing modules; and

a secondary power system configured to provide operational power for the actuator control modules, the sensing modules and the control interface when primary power to the equipment controller is not available, and which includes a load test system for determining whether the secondary power system is capable of operating under operational load conditions.

2. The equipment controller of claim 1, wherein the secondary power system comprises a battery and includes a charging system configured to maintains a sufficient charge in the battery to permit the battery to provide operational power for the actuator control modules, the sensing modules and the control interface when primary power to the equipment controller is not available.

3. The equipment controller of claim 1, wherein the actuator control modules and sensor modules are contained in a first housing separate from a second housing in which the control interface is contained.

4. The equipment controller of claim 3, wherein the first and second housings are water tight housings.

5. The equipment controller of claim 3, wherein at least portions of the secondary power system are contained in a third housing separate from the first and second housings.

6. The equipment controller of claim 5, wherein the first, second and third housings are water tight housings.

7. The equipment controller of claim 3, wherein the first and second housings are adapted for installation in or on one or more of:

underground vaults, ground level cabinets, or overhead utility poles.

8. The equipment controller of claim 1, further comprising a communications interface adapted for communications with an operations center remote from the equipment controller.

9. The equipment controller of claim 8, wherein the communications interface is adapted for wireless communications with the operations center.

10. The equipment controller of claim 8, wherein the communications interface includes a network interface adapted for use with fiber optic networks.

11. The equipment controller of claim 8, wherein the communications interface includes a network interface adapted for use with a cellular communications network.

12. The equipment controller of claim 8, wherein the communications interface includes a network interface adapted for use with a computer network.

13. The equipment controller of claim 8, wherein the communications interface is communicatively coupled to an antenna configured for installation at grade-level.

14. The equipment controller of claim 1, wherein the control interface is configured as a handheld unit adapted for use outside of a vault in which a housing that includes one or more of the actuator control modules and/or one or more of the sensing modules is located.

15. The equipment controller of claim 1, wherein the control interface is configured to indicate status of the monitored equipment parameters and control of the actuators.

16. An equipment controller, comprising:

one or more actuator control modules, each configured for connection to an actuator which provides operational control of a respective piece of monitored equipment;

one or more sensing modules, each configured to monitor a state of a parameter associated with each piece of monitored equipment;

a communications interface adapted for exchanging information regarding the monitored equipment and commands for the actuator control modules with an operations center remote from the equipment controller; and

a secondary power system configured to provide operational power for the actuator control modules, the sensing modules and the communications interface when primary power to the equipment controller is not available, and which includes a load test system for determining whether the secondary power system is capable of operating under operational load conditions.
