Patent Application
20050275549
The present invention relates generally to detection of emergency situations, such as, a fire, and more particularly to a method and system that provides network support for the detection and location of people trapped, for example, in a smoke filled area, such as, a stairwell in a building, during a fire.
Fire alarm systems in large buildings normally comprise a plurality of sensors, such as heat sensors or smoke detectors, which are located at predetermined positions throughout the building. These sensors are connected to a central control panel, which typically is located in a control room or security office. Conventional control or mimic panels may include a LED display comprising a series of LEDs corresponding to respective sensors. When a particular sensor is activated, for example by detecting heat or smoke in its vicinity, its corresponding LED on the control panel lights up or flashes to signal that its associated sensor is in an alarm condition.
Environmental alarm systems such as fire, smoke, and passive infrared systems, for example, generally have a central controller connected to multiple sensing stations placed in strategic remote locations. In some passive systems the control panel simply gives an indication that something is wrong. In other addressable systems more specific information can be obtained by periodically polling the remote sensors.
Environmental sensors such as fire, smoke, and infrared detectors usually produce analog voltage or current output signals. The amount or density of detected smoke, the temperature sensed by a heat sensor, or sensor performance degradation can be conveyed by variations in the voltage or current of the output signal. When a system is addressable, the address of each sensor is a coded analog signal. This allows a message from a sensor to include information about a monitored environmental condition along with the location of a source of smoke, an unauthorized entry into a space, or other detected alarm-producing conditions, for example. The identification signal is usually a pattern of current pulses compliant with a protocol established by the design of the alarm system.
Unfortunately, these known systems are not capable of providing information to rescue personnel of the location and condition of people that may be trapped in a burning building, for example. Many times people are trapped in locked smoke filled stairwells during a fire, despite the presence of firefighters in the vicinity. It is well known that people have lost their lives because it was not possible to quickly find them during the fire. Thus there is a need to identify these types of emergence situations in real time and to accurately pinpoint the location of trapped individuals.
The invention in one implementation encompasses an apparatus. The apparatus may be for the detection and location of people trapped in emergency situations. One embodiment of the apparatus may have: at least one detector having a predetermined location, the at least one detector structured to detect a respective predetermined event; a video camera operatively connected to the at least one detector; and a wireless communication device operatively connected to the at least one detector and to the video camera; wherein, upon detection of the predetermined event the detector activates the video camera and the wireless communication device to thereby transmit at least the occurrence of the predetermined event and video from the video camera.
The invention in another implementation encompasses a system. One embodiment of the system may have: at least one apparatus having a unique apparatus identifier, the apparatus having at least one detector having a predetermined location, the at least one detector structured to detect a respective predetermined event, having a streaming video camera operatively connected to the at least one detector, and having a wireless communication device operatively connected to the at least one detector and to the streaming video camera; and a monitoring center wirelessly connected to the wireless communication device. Upon detection of the predetermined event, the detector activates the streaming video camera and the wireless communication device to thereby transmit at least the apparatus identifier, the occurrence of the predetermined event and streaming video from the streaming video camera to the monitoring center.
Another implementation of the present invention encompasses a method that may have the steps of: detecting, via at least one detector having a predetermined location, a respective predetermined event; taking, upon occurrence of the predetermined event, streaming video, via a streaming video camera, of a surveillance area of the streaming video camera; placing, upon occurrence of the predetermined event, a cellular call to an emergency number at a monitoring center; sending to the monitoring center at least the predetermined location of the detector, the streaming video, and data indicative of a detection of the predetermined event; wherein, upon detection of the predetermined event, the detector activates the streaming video camera and the wireless communication device to thereby transmit at least the apparatus identifier, the occurrence of the predetermined event and streaming video from the streaming video camera to the monitoring center.
Features of exemplary implementations of the invention will become apparent from the description, the claims, and the accompanying drawings in which:
The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate an embodiment of the present invention and are not intended to limit the scope of the invention.
Embodiments of the present apparatus and method may provide for the detection and location of people trapped in emergency situations. Other emergency situations, as well as non-emergency situations, may be addressed by embodiments of the present apparatus and method.
One embodiment of the present apparatus, system and method provides an apparatus that combines a smoke detector and a streaming video camera with a preprogrammed mobile phone, such as a cell phone, to report the detection of smoke, for example, coupled with a live video feed of the affected area. The streaming video may or may not include audio. The detection of smoke triggers the device to connect to an emergency monitoring center and begin providing a live streaming video feed, allowing emergency personnel who arrive on the scene to accurately locate and assist people trapped, for example, in the building.
Streaming video is a sequence of “moving images” that are sent in compressed form over a network and displayed by the viewer as they arrive. Streaming media is streaming video with sound. With streaming video or streaming media, a user does not have to wait to download a large file before seeing the video or hearing the sound. Instead, the media is sent in a continuous stream and is played as it arrives. The user needs a player, which is a special program that uncompresses and sends video data to the display and audio data to speakers.
The detection and video apparatus may use an appropriate wireless data transmission method, such as IEEE 802.11, CDMA 3G-1X Data, CDMA 3G-EVDO, etc. to transmit, for example, the smoke detection event, and the streaming video. A GPS location device coupled with the apparatus may also be incorporated to provide accurate location information. Optionally, if the device is stationary/fixed, the location of the device or a device identifier may be configured within the device. If a device identifier is utilized, the emergency center may map the device identifier to the location of the device.
GPS stands for Global Positioning System. GPS was developed to allow the military to accurately determine their precise location anywhere in the world. GPS uses a collection of 24 satellites positioned in orbit to allow GPS equipment to automatically have its position triangulated to determine its location.
Although the present system and method may be used with any type of network (wired and wireless, for example), a subscriber may typically be a mobile subscriber who uses a mobile terminal (also referred to as mobile phone, a cell phone, mobile handset, or car phone).
