Room decontamination system, method and controller

A room UV decontamination system comprising:

• condition sensing hardware for detecting a room condition used in determining whether safe conditions for decontamination exist in a room, the condition sensing hardware being configured for generating sensor data indicative of the room condition in the room;
• UV decontamination hardware suitable for applying a decontamination operation to a room, the decontamination operation including irradiating the room with UV radiation;
• and
• a controller in communication with the condition sensing hardware for receiving the sensor data, the controller being configured for performing a determination that safe conditions exist for the decontamination operation based on the sensor data and initiating the decontamination operation at least in part based on the determination that safe conditions exist for the decontamination operation, wherein the controller is configured for determining, based on the sensor data, whether a decontamination operation is required, and wherein the controller is configured for determining whether a decontamination operation is required based on historical sensor data.

A method for decontaminating a room comprising:

• a receiving output from condition sensing hardware, the condition sensing hardware comprising at least a door sensor and a presence detector, the output comprising at least door sensor output and presence detector output;
• performing a confirmation based on the output from the condition sensing hardware that the presence detector is functioning properly;
• determining, based on the output from the condition sensing hardware, and based on the confirmation that the presence detector is functioning properly, that safe conditions for decontamination exist in the room;
• and
• at least in part in response to the determination that safe conditions for decontamination exist in the room, initiating a decontamination operation,
• wherein performing a confirmation that the presence detector is functioning properly comprises:
• determining based on the door sensor output an actual opening of the door,
• determining based on the presence detector output whether the actual opening of the door coincides with a detected presence, and
• confirming based on that a detected presence coincides with the actual opening of the door, that the presence detector is functioning properly.
