Abstract
The circuit monitoring device is disclosed. The device is for monitoring circuit resistance. At configurable thresholds digital flags are triggered, the device can be used as a Security/Building management system. The device uses open technology is fully scaleable and allows programmable logic controllers to be used as security management systems. Using a soft logic option a PC could take the place of the PLC.
Claims20
A device for monitoring the status of a circuit based on a measurable parameter of the circuit, the device comprising:
- measurement means to measure the parameter of the circuit;
- comparison means to compare the measured parameter to at least one threshold value and to assign a status based on a result of the comparison;
- transmission means to communicate the status over a network and to limit all communications over the network to only the status;
- and
- output means to present an indication of the assigned status.
An apparatus for monitoring a circuit comprising:
- a circuit monitor to measure a parameter of the circuit;
- a processor to convert the measured parameter to a status signal;
- a transmitter to transmit the status signal over a network, said transmitter limiting the transmission to only the status signal;
- and
- a display to receive the status signal and to present an indication of a status of the circuit based on the received status signal.
An apparatus for monitoring a circuit comprising:
- a circuit monitor to measure a parameter of the circuit;
- a processor to convert the measured parameter to a status signal;
- a transmitter to transmit the status signal over a network, said transmitter limiting a status transmission to only the status signal by transmitting only those few bits necessary to describe the status signal;
- and
- a display to receive the status signal and to present an indication of a status of the circuit based on the received status signal.
An apparatus for monitoring a circuit comprising:
- a circuit monitor to measure a parameter of the circuit;
- a processor to convert the measured parameter to a status signal;
- a transmitter to transmit the status signal over a network, said transmitter limiting a status transmission to only the status signal by transmitting only five bits from the circuit monitor;
- and
- a display to receive the status signal and to present an indication of a status of the circuit based on the received status signal.
An apparatus for monitoring a circuit and for coupling to a central system comprising:
- a module to measure a parameter of the circuit, to compare the measured parameter to a plurality of threshold values and to assign a status to the circuit based on the comparison;
- a communications module to communicate a signal indicative of the assigned status to the central system via a network, said communications module limiting all communications with the central system to only the signal indicative of the assigned status;
- and
- a display to present an indication of a status of the circuit based on the signal indicative of the assigned status.
An apparatus for monitoring a circuit and for coupling to a central system comprising:
- a circuit module to determine a status of the circuit;
- a network communications module coupled to the circuit module to communicate a signal indicative of the assigned status to the central system via a network, said network communications module limiting all communications with the central system to only the signal indicative of the assigned status;
- and
- a display to present an indication of a status of the circuit based on the signal indicative of the assigned status.
A method for monitoring a circuit comprising:
- measuring a parameter of the circuit;
- converting the measured parameter to a status signal;
- transmitting the status signal via a network;
- limiting all communications over the network to only the status signal;
- and
- presenting an indication of a status of the circuit based on the received status signal.
A method for monitoring a circuit comprising:
- measuring a parameter of the circuit;
- converting the measured parameter to a status signal;
- transmitting the status signal via a network;
- limiting all status communications over the network to only the status signal;
- and
- presenting an indication of a status of the circuit based on the received status signal, wherein said transmitting the status signal includes transmitting via a wireless link.
