Abstract
A method and apparatus for controlling a valve during the detection of a hazard event. A hazard event is defined as an event that may endanger the health or safety of people or the environment from contamination of hazardous material carried by a vehicle. The hazard event may be detected from a condition of the vehicle, an input received from a vehicle operator, or a message received from a remote location. After detecting a hazard event, a valve located on the vehicle is controlled to prevent contamination from the hazardous material being transported.
Claims14
A method for controlling a valve located on a vehicle, comprising:
- detecting a hazard event;
- transmitting a status message indicative of the hazard event to a remote location;
- receiving a second message in response to the status message, the second message comprising instructions for controlling the valve;
- and
- controlling operation of the valve upon detection of the hazard event.
Apparatus for controlling a valve located on a vehicle, comprising:
- means for detecting a hazard event;
- means for operating the valve;
- a transceiver being operable to transmit a status message to a remote location upon detecting the hazard event, the transceiver being further operable to receive a second message sent in response to said status message, the second message comprising instructions for controlling the valve;
- and
- means for controlling the operating means in response to the hazard event.
Apparatus for controlling a valve located on a vehicle, comprising:
- a transducer for detecting a parameter onboard the vehicle:
- a solenoid for controlling operation of the valve;
- a processor for determining a hazard event from the detected parameter;
- a transmitter for transmitting a status message, indicative of a hazard event, to a remote location;
- said processor being operable to receive a second message, including instructions for controlling the valve, in response to the status message, and sending a signal to the solenoid to control operation of the valve.
