Definitions

  • the present invention relates to a digital situation indicator, especially a personal monitoring and alarm system as defined in the preamble of claim 1.
  • firefighters When entering a burning building, firefighters wear breathing apparatus consisting of an air tank, regulator, facemask and pressure gage. Typically, firefighters work in dense smoke, where the visibility may be only a few inches.
  • Firefighters carry a personal alert safety system (PASS) device, which activates an audible alarm, if they stop moving.
  • the PASS device has a "Pre-Alert" stage, which allows the firefighter a pre-specified number of seconds to move or to shake the PASS device, before the alarm is activated.
  • PASS personal alert safety system
  • firefighters need to know certain information about their constantly changing situation in order to safely and efficiently perform their work.
  • the firefighter also needs to know the ambient temperature, its time-dependent effect on his or her cumulative heat stress level, and whether flashover conditions are impending. Before opening a door inside a burning building, the firefighter needs to know whether there is a raging fire on the other side. During so-called "mop-up" operations after the fire has been extinguished, firefighters typically have to use axes to inspect inside walls, to ensure that no hidden fires exist.
  • DE-A-19822142 discloses a system for supervising user, such as a fireman, who carries respiratory equipment.
  • the respiratory equipment carrier wears a mobile part which is connected to compressed air breather to assess and transfer data via a wireless connection to a remote base station, or a central station.
  • the mobile part is connected by a cord to earphones or a loudspeaker at the helmet of the respiratory equipment carrier such that the mobile device is able to give an audible spoken notification on the remaining air pressure, or an audible spoken alarm.
  • WO-A-93/03465 discloses a display located on the computer/sensor unit which is attached to firefighter's air cylinder hose.
  • US-A-5886822 discloses that head mounted image displays may be used in helmets, goggles and eyeglasses.
  • a helmet-mounted display system such as those used by military jet fighter pilots, which projects data onto the visor of the helmel, would offer firefighters a possible solution.
  • the cost of a single helmet could absorb an annual budget. The cost to equip all firefighters worldwide would be staggering.
  • the incident commander is in charge of all firefighters at the scene of the fire. Each firefighter gives the IC a personal accountability tag (PAT) upon arrival at the scene.
  • PAT personal accountability tag
  • the IC keeps track of the firefighters by the use of a unit identification pad (UIP) and a large marker board.
  • UIP unit identification pad
  • the drawback is that once the firefighters are inside the fire, the IC has no method of knowing how much air each firefighter has left, what temperature the firefighters are operating in, what is their heal stress level or PASS device status.
  • Firefighters, welders and warfighters are just examples for possible users of digital situation indicator of the invention. This kind of indicators can be utilised in many fields where personal monitoring and alarming are essential.
  • Information systems for example for divers, are known in the art. These systems include sensor modules, different kinds of display modules and also modules to send and receive data between the said modules. This kind of systems have been shown for instance in US patent specifications 5503145 , 5301668 and 5617848 .
  • a primary object of the present invention is to provide a digital situation indicator, especially a personal monitoring and alarm system that will overcome the shortcomings of the prior art devices.
  • Another object of the invention is to provide a new digital situation indicator.
  • the situation indicator SI of the invention offers a digital heads-up display HUD solution with a multitude of new features.
  • the SI offers a truly digital, very easily legible HUD, at a cost no more expensive than the existing technology.
  • the SI system has three separate units:
  • the sensor module may contain a pressure sensor, ambient temperature sensor, infrared (IR) temperature sensor, an "SOS” Button and an integrated PASS device.
  • a microprocessor anelyses the sensor data and computes air time remaining in minutes, heal stress level, and impending flashover danger.
  • the sensor module transmits sensor and computed data to both the HUD and the ICM.
  • the communication between the parts is wireless such as radio frequency (RF) communication.
  • RF radio frequency
  • the sensor module may also contain a amperage sensor.
  • the sensor module transmits sensor and computed data to the HUD using wireless communication, such as RF communication.
  • the heads-up display incorporates a miniature, transflective LCD display unit with electro-luminescent panel backlighting, and optical enhancement means consisting of an achromatic doublet lens, optimized to correct for on-axis spherical and chromatic aberrations.
  • the optics is designed for extra long eye relief, and the HUD is positioned in the accommodatemask so that it does not restrict the firefighter's forward field of view.
  • the firefighter before opening a door inside a burning building, the firefighter can point the IR sensor with a laser beam at the door, press the IR sensor button and read the temperature of the door on the HUD. During "mop-up" operations after the fire has been extinguished, the firefighter can scan the walls with the IR sensor to ensure that no hidden fires exist.
  • the incident commander module consists of a self contained, portable, one-piece computer module, with backlit LCD display, louch screen or flex-membrane keypad, and RF transceiver.
  • the ICM receives data transmissions from the sensor module.
  • the ICM can also transmit text messages to the firefighler. Once the firefighter is inside the fire, the ICM tracks each firefighter's situation, including elapsed time in the fire, air pressure, air time remaining in minutes, ambient temperature in the fire, heat stress level and PASS device status.
  • the sensor module SM in accordance with one embodiment of the invention, as shown in Fig 1 , has the following parts and features:
  • the operation of the flashover warning software is described in the flow chart of the Fig. 15 .
  • the rate of increase of ambient temperature is compared to the pre-specified alarm limit. If the rate of increase of ambient temperature is lower than the limit, the program returns to the beginning. If the rele of increase of ambient temperature is higher than the pre-specified alarm limit, a flashover warning is displayed in the HUD. A flashover warning is also transmitted to tha incident commander module;
  • the operation of the motion sensor program is described in the flow chart of the Fig. 17a and 17b , First the pre-specified alarm limits and the motion sensor are read and the real time clock is started. Then the motion is stored in to the memory as a function of time. If the motion slops, time period of zero motion is calculated.
  • program If the time period of zero motion is shorter than the pre-specified limit, program returns to the beginning. Otherwise a countdown timer and a vibrator alarm are activated. Simultaneously zero motion warning and countdown timer data is displayed in the HUD. A zero motion warning is also transmitted to the incident commander module.
  • the motion sensor is read again. If motion is detected, the countdown timer is reset and a all clear messaga is transmitted to the incident commander module, and the program returns to the beginning. Otherwise the countdown timer is checked, and if there is still time left, motion sensor is read again. If countdown timer has reached zero, an audible alarm is activated and an alarm message is trensmitted to the incident commander module.
  • the sensor module SM is attached to the pressure gage hose 15 of the air tank 2 as shown in Fig. 4 .
  • the sensor module SM has a connector 16 to the pressure hose 15, a housing 17 for the electronic circuitry (shown in Fig. 1 ) of the sensor module SM , RF antenna 18, IR-sensor and ambient temperature sensor in their housing 19, a waterproof switch 10 for IR-sensor 9 ( Fig. 1 ), a laser 11 and SOS-button 20.
  • the heads-up display HUD is an optielectric, night-readable display which is mounted in a facemask F of the firefighter, as shown in Fig, 8 and Fig. 9 .
  • the heads-up display module HUD as shown in Fig. 4 , has the following parts and features:
  • the incident commander module ICM of one embodiment of the present invention provides the incident commander, who is commanding the operation, with real-time sensors data on all firefighters in the interior of the building or equivalent.
  • the incident commander module ICM as shown in Fig. 5 and Fig. 14 has the following parts and features:
