System and method of monitoring an electronic discharge device in an air purfication system
View Patent ↗A method and system of remotely monitoring an operational status of electronic discharge devices in an air purification system senses emitted radiation at a location proximate the air purification system, alone or in combination with a determination of an amount of time remaining in an operational lifetime of the electronic discharge device, or an amount of power delivered to at least one of the electronic discharge devices. A determination of the operational status of at least one of the electronic discharge devices is made based on at least emitted radiation, and the status information is transmitted to a remote monitoring unit that receives the status information and displays an indicator of operational status. In one embodiment, the operational status of a UV-C germicidal lamp may be monitored using optically sensitive devices located within a purification system.
1. A method of remotely monitoring an operational status of a plurality of electronic discharge devices in an air purification system, comprising:
sensing an operational characteristic of said plurality of electronic discharge devices;
determining an operational status of said plurality of electronic discharge devices based on the operational characteristic sensed; and
indicating the operational status of said plurality of electronic discharge devices based on said determining,
wherein said plurality of electronic discharge devices comprises a first group of electronic discharge devices and a second group of electronic discharge devices and said operational characteristic is a difference between one or more electrical properties of said first group of electronic discharge devices and said second group of electronic discharge devices;
wherein said operational characteristic is a difference in the relative current of said first and second groups of electronic discharge devices;
wherein determining an operational status of said plurality of electronic discharge devices comprises determining whether said difference in the relative current of said first and second groups of electronic discharge devices exceeds a predetermined threshold; and
wherein said predetermined threshold of current differential between the first and second groups of electrical discharge devices is between 5% and 10%.
2. The method of claim 1 , wherein indicating the operational status of said plurality of electronic discharge devices comprises illuminating or extinguishing an indicator light.
3. The method of claim 1 , wherein indicating the operational status of said plurality of electronic discharge devices comprises transmitting a status signal indicating the operational status of said plurality of electronic discharge devices to a location remote from said plurality of electronic discharge devices.
4. The method of claim 1 , wherein at least one of said plurality of electronic discharge devices includes an ultra-violet (UV) lamp configured to emit germicidal radiation.
5. The method of claim 1 , further comprising:
detecting whether one or more of said plurality of electronic discharge devices is receiving electrical power.
6. The method of claim 5 , wherein said determining an operational status of said plurality of electronic discharge devices is based on the operational characteristic sensed and said power detecting.
7. A device for remotely monitoring an operational status of a plurality of electronic discharge devices in an air purification system, comprising:
means for sensing an operational characteristic of said plurality of electronic discharge devices;
means for determining an operational status of said plurality of electronic discharge devices based on the operational characteristic sensed; and
means for indicating the operational status of said plurality of electronic discharge devices based on said determining,
wherein said plurality of electronic discharge devices comprises a first group of electronic discharge devices and a second group of electronic discharge devices and said operational characteristic is a difference between one or more electrical properties of said first group of electronic discharge devices and said second group of electronic discharge devices;
wherein said operational characteristic is a difference in the relative current of said first and second groups of electronic discharge devices;
wherein said determining means is configured to determine an operational status of said plurality of electronic discharge devices by determining whether said difference in the relative current of said first and second groups of electronic discharge devices exceeds a predetermined threshold;
wherein said predetermined threshold of current differential between the first and second groups of electrical discharge devices is between 5% and 10%.
8. The device of claim 7 , wherein said means for sensing include one or more current sensing loops.
