CLOSE PROXIMITY RFID TAG AND MONITORING SYSTEM

摘要

A system for monitoring hand washing compliance that includes a plurality of sensors installed in a space to detect the presence of or proximity of personnel to key areas; and a controller operatively coupled to the sensors, the controller being programmed to analyze sensor inputs to determine if personnel are washing their hands in a manner compliant with a set of requirements, and a networked data storage and reporting system operatively coupled to the controller and configured to provide reports of hand washing compliance. The sensors are installed on a ceiling over the space and an LED light illuminates a hand washing area for an interval of time that begins in response to detection by one of the plurality of sensors that a user is in proximity to the sink and ends when hand washing compliance is complete.

1. A system for monitoring hand washing at a hand washing station having a sink and a soap dispenser, comprising:
an interrogator located in a ceiling in proximity to the hand washing station and configured to transmit interrogation signals and to receive responsive backscattered signals and to transmit data signals to the processor and the memory; a first sensor located in the ceiling above the soap dispenser and structured to detect the presence of the user's hands in close proximity to the soap dispenser; a second sensor located in the ceiling above the sink and structured to detect the presence of the user's hands in close proximity to or in the basin of the sink; an LED light located on the ceiling above the sink and structured to visibly illuminate the sink for an interval of time in response to detection of the user by the second sensor; an RFID tag configured to be worn on or in close proximity to a user's body, the tag including:
a radio frequency circuit configured to receive and modulate an interrogation signal for backscatter transmission; andan antenna configured to resonate in response to the interrogation signal when in close proximity to the human body; and a computer processor coupled to the interrogator and configured to receive the data signals from the interrogator to determine a presence of the user and to process the same and generate reports pertaining to use of the hand washing station by users, the computer processor further coupled to the LED light and configured to control the interval of time the LED light illuminates the sink.
