Room decontamination system, method and controller

Abstract

A room decontamination systems, controllers and methods for decontaminating a room. The room decontamination system may be a UV room decontamination system that uses UV radiation to perform a decontamination operation in the room. A controller may determine whether safe conditions for decontamination exist and initiate a decontamination operation on the basis of whether they exist. Determination of safe conditions for decontamination may be based on light actuation detection and/or sensor data, which may include presence detector data and door sensor data. Determination of safe conditions for decontamination may include a determination of whether sensors are functioning properly. The controller may also determine whether decontamination operations are required on the basis of the historical condition data, for example on the basis of whether the room has been occupied since the last decontamination operation.

         42 . A room UV decontamination system comprising:
 a. a door sensor configured for installing in relation to a door and detecting the status of the door to generate an output indicative of the status of the door;   b. UV decontamination hardware for applying a decontamination operation to a room, the decontamination operation including irradiating the room with UV radiation;   c. a controller in communication with the door sensor and the UV decontamination hardware, the controller being configured for performing a determination that safe conditions exist for the decontamination operation and initiating the decontamination operation at least in part on the basis of the determination of safe conditions;   d. wherein the controller comprises a logging system configured for generating decontamination operation data representative of decontamination operations initiated by the controller and for populating a historical decontamination operations log with the decontamination operation data;   e. a memory device for storing the historical decontamination operations log; and   f. a data interface for transmitting at least a portion of the decontamination operation log to a remote device.   
     
     
         43 . The room UV decontamination system of  claim 42 , further comprising:
 a presence detector for detecting the presence of a body in proximity to the door and generating an output indicative of a detected presence, wherein the determination of safe conditions comprises a confirmation that the presence detector is functioning properly.   
     
     
         44 . The room UV decontamination system of  claim 42 , wherein the historical decontamination data comprises a list of past decontamination operations that were completed. 
     
     
         45 . The room UV decontamination system of  claim 42 , wherein the historical decontamination operations log is a report indicative of whether the room meets a hygienic standard. 
     
     
         46 . The room UV decontamination system of  claim 45 , wherein the controller is configured to generate an alert in response to a determination that the room does not meet the hygienic standard. 
     
     
         47 . The room UV decontamination system of  claim 42 , wherein the data interface is a wireless data interface.
