Abstract
An exit obstruction warning device monitoring an exit door and broadcasting an alert regarding an obstruction blocking the exit door is provided. The exit obstruction warning device includes a sensor, a processing module, and an output module. The sensor monitors the exit door for the obstruction. The output module broadcasts an alarm notification in response to the obstruction. The processing module receives a signal from the sensor that describes the obstruction blocking the exit door. The processing module processes the signal and operates the output module based on the signal.
Claims17
An exit obstruction warning device comprising:
- a sensor, wherein the sensor is configured to monitor an exit door for an obstruction;
- an output module, wherein the output module is configured to broadcast an alarm notification;
- a processing module coupled to the sensor and the output module, wherein the processing module is configured to:
- receive a first signal from the sensor;
- analyze the first signal;
- detect the obstruction blocking the exit door from an analysis of the first signal;
- identify a personnel at a location proximate to the output module from the first signal;
- instruct the output module to broadcast the alarm notification;
- receive a second signal from the sensor;
- analyze the second signal;
- detect a removal of the obstruction blocking the exit door from an analysis of the second signal;
- and
- instruct the output module to terminate a broadcast of the alarm notification in response to receiving the second signal.
An exit obstruction warning system comprising:
- a sensor comprising a camera component and an ultrasound emitter and detector, wherein the sensor is configured to monitor an exit door;
- an output module, wherein the output module is configured to broadcast an alarm notification;
- a processing module coupled to the sensor and the output module, wherein the processing module is configured to:
- receive a signal from the sensor;
- analyze the signal;
- identify an obstruction blocking the exit door from the analyzed signal;
- instruct the output module to broadcast the alarm notification during an initial time period;
- detect a failure to receive a new signal from the sensor during the initial time period, wherein the new signal is expected to describe a removal of the obstruction blocking the exit door;
- and
- instruct the output module to continue to broadcast the alarm notification.
A method of providing an exit obstruction warning system, the method comprising:
- receiving at least one signal from a sensor with an ultrasound emitter and detector, wherein the at least one signal describes detected reflections of ultrasound waves reflected from an obstruction blocking an exit door;
- processing the at least one signal,
- wherein the processing of the at least one signal includes:
- analyzing a first signal;
- detecting the obstruction blocking the exit door based on an analysis of the first signal;
- identifying a personnel at a location proximate to the output module from the first signal;
- instructing the output module to broadcast an alarm notification based on the analysis of the first signal;
- receiving a second signal from the sensor;
- analyzing the second signal;
- detecting a removal of the obstruction blocking the exit door based on an analysis of the second signal;
- and
- instruct the output module to terminate a broadcast of the alarm notification in response to the analysis of the second signal;
- and
- wherein the alarm notification includes one or more of an audible alarm notification and a visual alarm.
