Abstract

An apparatus includes a plurality of power distribution control output channels operatively coupled to at least one power source, and comprising an access control input from an access control device, and a control output for a controlled device. A controller receives an access control input signal for each power distribution control output channel and provides a control signal to each power distribution control output channel such that each power distribution control output channel provides a control output signal according to requirements of a corresponding controlled device. The controller can individually isolate one or more power distribution control output channels from the at least one power source such that the control output signal is removed from the corresponding controlled device, while any other power distribution control output channels coupled to the same power source continues to operate without interruption.

Claims

1. An apparatus comprising:

a first processor operatively coupled to a first set of interface ports comprising DC voltage input ports and current input ports, the first processor operative to convert DC voltage and current analog data to DC voltage and current digital data;

a second processor operatively coupled to the first processor, to a second set of interface ports, and to at least one network interface port, the second processor operative to;

obtain digital data via the second set of interface ports and obtain DC voltage and current digital data from the first processor;

obtain device operating parameters and alert condition notifications related to device faults or potential device failure for a plurality of digital and analog devices, from the digital data and the DC voltage and current digital data;

obtain updates to operating parameters from a remote device over the at least one network interface port;

provide updates to device operating parameters over the second set of interface ports; and

a power supply board comprising;

an AC-to-DC power supply and a battery charger operatively coupled to the power supply; and

a third processor, operatively coupled to the battery charger and to the second processor via one of the second interface ports, the third processor operative to;

obtain battery charger programming commands from the second processor, and update battery charger data in response to the programming commands;

monitor the power supply and the battery charger for fault conditions;

switch a power bus to battery power in response to a power supply fault condition or loss of AC power;

send control commands to local fault reporting devices in response to detection of a fault condition; and

enable the second processor access to fault report data corresponding to the fault condition.

2. The apparatus of claim 1, comprising:

an SNMP (Simple Network Management Protocol) agent, executable by the second processor, operative to write and email a report conforming to a plurality of configurable report settings in response to occurrence of a device alert condition.

3. The apparatus of claim 1, comprising:

a web server, executable by the second processor, operative to provide a user interface accessible by a remote device via the network interface port connected to the Internet, such that the remote device can receive data from, and provide programming outputs for, connected devices operatively coupled to the second processor via the second interface ports.

4. The apparatus of claim 1, wherein the second processor is further operative to:

detect and identify each device operatively coupled via the first set of interface ports and the second set of interface ports;

determine an alert condition for each device; and

write and email an individual report for each device in response to occurrence of a corresponding determined device alert condition for a corresponding device.

5. A distribution monitor and control (DMC) board, operative to receive DC power inputs from each of a plurality of power supply boards, the DMC board comprising:

a plurality of DC power buses, each DC power bus corresponding to a power supply board DC power input;

a set of power distribution channels, each power distribution channel operatively coupled to one of the DC power buses, and comprising a control input terminal and an output device having a control output terminal, the output device operative to provide a control output signal at the control output terminal to control a plurality of external device types; and

a controller, operatively coupled to each power distribution channel, the controller operative to;

receive a control input signal received at the control input terminal for a corresponding power distribution channel, with each control input signal being a control input signal selected from a group consisting of;

a normally closed contact input, a normally open contact input, an open collector input, and a direct voltage input;

control the corresponding output device of the corresponding power distribution channel to provide the control output signal at the control output terminal in response to the control input signal; and

isolate each power distribution channel individually by controlling the corresponding output device to remove the control output signal.

6. The DMC board of claim 5, where the plurality of power supply boards each comprises:

an AC-to-DC power supply;

a battery charger operatively coupled to the power supply; and

a processor operatively coupled to the battery charger.
