Monitoring module for hot water heater diagnostic device
View Patent ↗A monitoring module for connection to a diagnostic device having two or more light emitting sources for indicating operating fault conditions of an apparatus. The monitoring module feeds information signals to a communication link for reception at a remote location. The monitoring module is secured over a series of light emitting diodes of the diagnostic device and reproduces these for local access. The series of LED's indicate fault conditions of the apparatus which in this embodiment is a hot water heater. Accordingly, the operation of the hot water heater at its fault status can be monitored from a remote location and on site.
1. A monitoring module for permanent connection to a diagnostic device having a display panel provided with two or more light emitting sources for indicating operating fault conditions of a water heater, said monitoring module feeding information signals through a communication link for reception at a remote location, said monitoring module comprising a housing permanently secured to said diagnostic device, said housing being provided with a housing section configured to extend over said display panel to conceal said two or more light emitting sources of said diagnostic device, said monitoring module having two or more visible light emitting sources corresponding to said two or more light emitting sources of said diagnostic device concealed by said housing section of said monitoring module to replicate locally on said housing the condition of said two or more light emitting sources of said diagnostic device for local display on said housing of the state of said concealed two or more light emitting sources of said diagnostic device, an isolated light conducting solid medium disposed at a detecting end adjacent respective ones of said two or more light emitting sources of said diagnostic device, said isolated light conducting solid medium having an opposed end terminating at an outer surface of said monitoring module and constituting said two or more light emitting sources of said monitoring module, and optical detectors in said monitoring module for detecting the condition of said two or more light emitting sources of said light conducting solid medium and providing said information signals fed to said remote location through said communication link.
2. The monitoring module as claimed in claim 1 wherein there are a plurality of said light emitting sources and visible corresponding light emitting sources, and wherein one or a combination of said concealed light emitting sources when lit provides an indication of a specific diagnostic condition of said apparatus.
3. The monitoring module as claimed in claim 2 wherein said light emitting sources of said diagnostic device are light emitting diodes.
4. The monitoring module as claimed in claim 1 wherein one of said two or more concealed light emitting sources concealed by said housing section, when lit, indicates that the diagnostic device is functional, the others of said concealed light emitting sources indicating fault conditions.
5. The monitoring module as claimed in claim 1 wherein said isolated light conducting mediums are constituted by fibre optics bundles isolated from one another.
6. The monitoring module as claimed in claim 1 wherein said isolated light conducting mediums are constituted by light transmitting glass rods.
7. The monitoring module as claimed in claim 1 wherein there is further provided a micro-controller circuit in said monitoring module, said micro-controller circuit having a processor for processing status and alarm signals, and a transmitter for transmitting said status and alarm signals to a remote location.
8. The monitoring module as claimed in claim 1 wherein said means to secure said monitoring module to said diagnostic device is one of a clamp, screws or adhesive.
9. The monitoring module as claimed in claim 7 wherein there is further provided a sensor switch associated with said monitoring module and micro-controller to generate an alarm condition if said monitoring module is incorrectly secured or removed from said diagnostic device, and an audible alarm associated with said monitoring module.
