Electronic security system
View Patent ↗An electronic security system. The system includes a plurality of electronic security devices. Each of these devices includes an input/output module that receives and decodes electronic signals and governs the functionality of the electronic security device. The system also includes a power supply module. The power supply module sends electrical power and modulated commands to the plurality of electronic security devices over power lines.
1. An electronic security system comprising:
a power line having exactly two wires;
a power supply electrically connected to the power line and including a power supply module,
the power supply module configured to receive electrical power, to selectively receive operational instructions, to modulate the electrical power with the operational instructions, and to supply the modulated electrical power through the power line;
a plurality of electronic security devices electrically connected to the power line, and configured to be powered with the modulated electrical power from the power line,
each including an input/output module configured to receive the modulated electrical power, to decode the modulated electrical power to retrieve the operational instructions, to program the electronic security device based on the retrieved operational instructions, and to operate the electrical security device with the modulate electrical power and the programmed operational instructions;
wherein the power supply module also includes a multiple power supply module interface configured to couple the power supply module to and to transmit programming signals to another power supply module of another electronic security system via a line.
2. The system of claim 1 , further comprising a programming tool connectable to and disconnectable from the power supply module to communicate information from the programming tool to the power supply module.
3. The system of claim 2 , wherein the programming tool is a hand-held device.
4. The system of claim 2 , wherein the communicated information comprises at least one of a program and a command.
5. The system of claim 2 , wherein the programming tool further comprises an access screen configured to access and control the electronic security devices.
6. The system of claim 1 , further comprising a programming tool connectable to and disconnectable from the power lines to communicate information from the programming tool to the power supply module.
7. The system of claim 6 , wherein the programming tool is a hand-held device.
8. The system of claim 6 , wherein the communicated information comprises at least one of a program and a command.
9. The system of claim 6 , wherein the programming tool further comprises an access screen configured to access and control the electronic security devices.
10. The system of claim 1 , wherein the power supply includes a communication port allowing the power supply to be connected to an external peripheral device.
11. The system of claim 10 , wherein the external peripheral device includes one of a computer, a printer, and a monitor.
12. The system of claim 1 , further comprising a programming tool configured to communicate with the power supply module wirelessly.
13. A method of establishing an electronic security system comprising the steps of:
receiving the electrical power at a power supply;
modulating the electrical power with a plurality of operational instructions at a first power supply module of the power supply;
supplying the modulated electrical power from the power supply through a two-wire bus to first and second input/output modules connected to the two-wire bus, the first and second input/output modules associated with first and second electronic security devices, respectively;
retrieving the operational instructions from the modulated electrical power at the respective first and second input/output modules;
operating the respective first and second electronic security devices with the electrical power from the power supply module and based on the retrieved operational instructions;
connecting and communicating bi-directionally between a multiple power supply module interface of the first power supply module and a second power supply module of a second electronic security system; and
mapping at least a portion of the operational instructions to a third electronic security device of the second electronic security system via the multiple power supply module interface.
14. The method of claim 13 , further comprising uploading the operational instructions onto the power supply module from an electrically and mechanically connected computer at the bus.
15. The method of claim 14 , wherein the computer is a hand-held computer.
16. The method of claim 15 , wherein the hand-held computer comprises one of a personal digital assistant, a palm-top computer, and a pocket personal computer (“PC”).
17. The method of claim 14 , wherein uploading the operational instructions onto the power supply module (“PSM”) comprises wirelessly communicating the operational instructions to the PSM.
18. The method of claim 13 , further comprising controlling at least one of the first and the second security devices with a programming tool.
19. The system of claim 1 , wherein each electronic security device includes a sensor, a horn, a shear lock, a magnetic lock, an electric strike, an actuator, a button, a motion sensor, a door positioning switch, an electric lock, an exit device, a desk console, a monitor strike, a magnetic switch, a key switches, a keypad, or a card reader.
20. The method of claim 13 , further comprising programming the respective first and second electronic security devices based on the retrieved operational instructions.
