Definitions

  • the invention relates to a safety device with at least one in a room to be monitored arranged gas sensor, which occurs when Fuel gas in the room preventing the supply of Fuel gas and power supply for one too supplying complex, whereby the Gas sensor operation in the event of a power failure by one electric battery is maintained.
  • Such a safety device is through the DE-A1-32 08 553 known.
  • the one described there Gas safety device is a cable from the gas sensor led to the gas main tap, which is a servomotor is associated with the occurrence of fuel gas in the room to be monitored by an electrical Battery via a gas sensor contact and the cable is supplied with electricity and the gas main tap closes; at the same time the main power line disabled. That way prevents the complex to be supplied, for example a house, continue with fuel gas and Power is supplied, causing an explosion is prevented.
  • DE-U1-89 13 816 an intrinsically safe gas detector for residential buildings known, in which gas detection sensors are located in a room are in the escaping gas probably accumulates first.
  • the Gas detection sensors are intrinsically safe, while a more comprehensive share of the supply Device part of the gas detector is not intrinsically safe is executed and located in a room other than the gas sensors is located. In the event of a power failure of the public network is taken over by a battery Continued operation of the gas detector.
  • DE-A1-38 03 892 Gas warning system known in which a number of Pressure sensors, each the gas pressure, the Temperature and the amount of from a gas bottle Measure the emitted fuel gas to a central module are connected, depending on Faults in the measured values sound an alarm or visually there and which prevents the Gas delivery of the gas bottles causes.
  • gas sensors The formation of gas sensors is general known, such as the essay "Sensor Technology” by Gerhard Wiegleb, published in Franzis electronics book, 1986, chapter 5, p.93-111, can be seen.
  • the gas sensors described there can include hydrocarbons, Determine carbon monoxide or oxygen.
  • the sensors of the known safety devices speak only on hydrocarbon gases, namely Natural gas, methane or propane.
  • a portable gas analyzer is known from US 4,485,666 known to take a gas sample through a Carbon monoxide sensor cell, one Oxygen sensor cell and a methane ⁇ sensor pumps and continuously all critical Indicates gas concentrations. Nevertheless, there are neither in this gas analyzer Motion detector attached, is still Preventing the supply of the fuel gas and the Power supply in a room to be monitored intended.
  • the object of the invention is a Safety device of the type mentioned at the beginning create their function at the measurement location of the gas sensor is expanded. It should also be possible to deliberate manipulation at the location of the gas sensor, for example, clogging the air supply opening of the gas sensor housing.
  • the safety device is very sensitive to dangerous Air compositions.
  • a further embodiment of the invention is thereby characterized in that the transmission of the signals from the sensors to the the suppression of the supply of the fuel gas and the Means effecting power supply wirelessly, preferably by radio. This allows the Safety device with minimal effort, without Masonry work for laying cables, be installed.
  • the safety device according to Fig. 1 (detector system) consists of three of each other entirely independent sensors 10. Each of these three sensors only responds to a gas.
  • the first sensor 10/1 responds to oxygen. The measured value drops slightly below the normal value found in the air is present (20.9%), the alarm is triggered.
  • the second sensor 10/2 reacts to natural gas / propane gas. At a total concentration higher than 0.5 or 1%, the alarm is triggered.
  • the third Sensor 10/3 reacts to carbon monoxide. exceeds the CO value becomes the concentration of 100 ppm Alarm triggered.
  • the one described above Detector system includes sensors that according to the current state of the art are already known.
  • the three sensors in one Detector system are housed. Is through one of the three sensors triggered an alarm Interruption of the power network or main switch 12 and the gas supply in line 14 through a Solenoid valve 16, for the entire building.
  • the Transmission of the signal from the sensor to the main switch 12 and / or the solenoid valve 16 can be by cable or wireless, e.g. by radio. Especially It is advantageous to transmit the control signals by radio to send, creating an additional and elaborate Cable laying is no longer required.
  • the Interruption of the mains voltage causes the closing of the solenoid valve so that the entire gas supply is interrupted.
  • Carbon monoxide is produced in every combustion process. If such a situation occurs, an alarm is raised triggered and the electricity and gas supply interrupted, long before a dangerous one Concentration of carbon monoxide can arise.
  • the oxygen sensor has the task of electricity and Shut off gas if a fire or if someone broke the entire facility specifically want to shut down (suicide).
  • the sensor measures one lower oxygen content, causing alarm triggered and the electricity and gas supply interrupted become.
  • This sensor only reacts to methane / propane. If so for some reason unburned gas in the Space flows, e.g. Leak in a pipe or open Gas tap, so an alarm is triggered and the whole Electricity and gas supply is interrupted. This is possible because in this case the solenoid valve is not more directly connected to the electrical current but to the detector battery.
  • the Solenoid valve is also used in the event of a power failure (220 V) due to a defect in the power supply from the im Detector built-in battery (18) in the open Condition kept.
  • the detectors control it Solenoid valve, whereby the gas supply is interrupted becomes.
  • the detectors can also be used optical and acoustic signal systems his. The two different information (optical and / or acoustic) are by the electrical current of the system described maintained. A more detailed description of the individual detectors are unnecessary since here advantageously known and proven detectors can be used.
  • Detectors that are sensitive to other information, e.g. Explosion, react, install.
  • sensors result from the fact that the three gases are typical of such situations, an explosive (deadly) mixture form that explodes on inflammation and rapid and can cause acute poisoning.
  • the device can be used in industrial applications currently known and common production techniques for sensors as well as for electro valves be equipped.
  • the system also prevents fires in front.
  • Devices with the proposed system can with a large number of detectors be equipped, one for each room in the Hazardous area connected to the main detector be the only one the different Controls with all its functions. It is a subsidiary application because their realization use one in the field of Electrical engineering technology already known presupposes.
  • the housing of the devices in which the Sensors and other devices housed are well known, and their shape does not affect the principle of application.
  • the outer casing can be made of metal or plastic exist and the shape of a three-dimensional Have parallelepipedon, with one suitable recess for the passage of said volatile elements and with a special Arrangement of the sensors inside the housing. It It is also possible to use the system in different ways Apartments of a building with a single To accommodate power source (battery or the like) that are not of normal Power supply is dependent.
  • FIG. 5 shows an arrangement of sensors in one Housing 20 shown in the form of a cubic Parallelepipedons is formed, but also in shape a hemisphere can be formed and with a central opening 21 is provided.
  • sensors motion detectors
  • 10/1 ', 10/2', 10/2 ", 10/3 ' These sensors are in the Middle of the housing 20 suspended so that the through the opening 21 entering the housing 20 Indoor air reaches them immediately. A deliberate, malicious clogging of the opening 21 is detected by sensor 10/1.
