Abstract
A safety system for a gas-operated apparatus for generating energy, in particular in a vehicle, includes at least one sensor for measuring the gas concentration. The sensor is preferably disposed in the passenger compartment of the vehicle. In the event of a dangerously high gas concentration, a fan and/or power window control is triggered via a control unit in such a way that the fastest possible air exchange in the passenger compartment of the vehicle results.
Claims13
A safety system for a gas-operated apparatus for generating energy, in which the apparatus, optionally along with a gas supply, is disposed in the vicinity of an occupied space but spatially separated from it, the safety system comprising
- at least one gas-sensitive sensor (6) in the occupied space;
- a control unit (7), which evaluates the output signal of the sensor (6);
- and
- means for reducing the gas concentration in the occupied space;
- the control unit (7), being operable to reduce the gas concentration in the occupied space as a function of the gas concentration ascertained by the sensor (6), wherein the gas-operated apparatus for generating energy is disposed in a vehicle (1);
- and wherein the occupied space is the passenger compartment of a vehicle, further comprising power control means (8) responsive to the control unit (7) operable to interrupt the power supply to the vehicle (1) as a function of the potential danger based on the gas concentration ascertained by the sensors (2, 6).
A safety system for a gas-operated apparatus for generating energy, in which the apparatus, optionally along with a gas supply, is disposed in the vicinity of an occupied space but spatially separated from it, the safety system comprising
- at least one gas-sensitive sensor (6) in the occupied space;
- a control unit (7), which evaluates the output signal of the sensor (6);
- and
- means for reducing the gas concentration in the occupied space;
- the control unit (7), being operable to reduce the gas concentration in the occupied space as a function of the gas concentration ascertained by the sensor (6), wherein the gas-operated apparatus for generating energy is disposed in a vehicle (1), and wherein the occupied space is the passenger compartment of a vehicle (1), further comprising a second sensor (2), which is disposed outside the passenger compartment of the vehicle (1), wherein, when a harmful concentration of hydrogen gas is measured in the engine compartment of the vehicle (1) by the sensor (2), the control unit (7) triggers at least the fresh-air valve (3) in such a way that it is in the closed position.
A safety system for a gas-operated apparatus for generating energy, in which the apparatus, optionally along with a gas supply, is disposed in the vicinity of an occupied space but spatially separated from it, the safety system comprising
- at least one gas-sensitive sensor (6) in the occupied space;
- a control unit (7), which evaluates the output signal of the sensor (6);
- and
- means for reducing the gas concentration in the occupied space
- the control unit (7) being operable to reduce the gas concentration in the occupied space as a function of the gas concentration ascertained by the sensor (6), wherein the gas-operated apparatus for generating energy is disposed in a vehicle (1);
- and wherein the occupied space is the passenger compartment of a vehicle (1), and wherein a safety valve disposed in the region of the roof of the vehicle (1) can be opened by the control unit (7) to reduce the gas concentration in the occupied space as a function of the gas concentration ascertained by the sensor (6).
