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.
Claims39
A circuit monitoring device, comprising:
- one or more processors, each having a memory and an input electrically coupled to a circuit which is configured to receive a measured electrical parameter of the circuit, and modules comprising software to configure the one or more processors, the modules including:
- a comparison module configured to compare a digital value, which corresponds to a magnitude of the measured electrical parameter, to a plurality of threshold values stored in the memory, wherein the plurality of threshold values define a respective plurality of ranges of digital values, each range corresponding to one of a plurality of conditions of the circuit including a normal condition and at least one alarm condition, and
- assign a status based on the digital value being within a particular range defined by one or more of the plurality of threshold values,
- a communication module configured to generate a status signal including at least the assigned status;
- and
- a transmitter configured to transmit the status signal to a centralized system over a network for output, by the centralized system, of the status.
3 more elements
A security management system, comprising:
- at least one circuit monitoring device, each circuit monitoring device comprising:
- one or more processors,
- a memory,
- an input electrically coupled to a circuit, and
- a transmitter configured to transmit a status signal over a network;
- wherein at least one of the one or more processors is configured to operate upon a measured electrical parameter of the circuit electrically coupled to the input via software included in modules, including:
- a comparison module configured to
- compare a digital value, which corresponds to the measured electrical parameter, to a plurality of threshold values stored in the memory, wherein the plurality of threshold values define a respective plurality of ranges of digital values, each range corresponding to one of a plurality of conditions of the circuit including a normal condition and at least one alarm condition, and
- assign a status based on the digital value being within a particular range defined by one or more of the plurality of threshold values, and
- a communication module configured to generate the status signal including at least the assigned status;
- and
- a centralized monitoring system communicatively coupled to the at least one circuit monitoring device, the centralized monitoring system having one or more processors configured via software included in modules, including,
- a central communication module, configured to receive the status signal including the assigned status from the at least one circuit monitoring device over the network, and
- a monitoring module configured to output the assigned status on a display.
11 more elements
A method for monitoring a circuit using a circuit monitoring device, comprising:
- receiving, using one or more processors configured by software within one or more modules, a parameter of a circuit;
- comparing, using the one or more configured processors, a digital value, which corresponds to a magnitude of the parameter of the circuit, to a plurality of threshold values wherein the plurality of threshold values define a respective plurality of ranges of digital values, each range corresponding to one of a plurality of conditions of the circuit including a normal condition and at least one alarm condition;
- assigning, using the one or more configured processors, a status according to the digital value being within a particular range defined by one or more of the plurality of threshold values;
- and
- transmitting, using a transmitter, the status to a central monitoring system.
