Abstract
A charge station is provided for filling a gas cylinder with gas. The charge station includes a gas output port configured to be fluidly connected to a supply of gas. The gas output port is configured to be fluidly connected to the gas cylinder for filling the gas cylinder with gas from the supply of gas. The charge station also includes a control system operatively connected to the gas output such that the control system is configured to control filling of the gas cylinder, and a radio frequency identification (RFID) reader operatively connected to the control system, the RFD reader configured to read data from an RFID tag on the gas cylinder.
Claims7
A method for filling a gas cylinder for a self-contained breathing apparatus (SCBA) with gas using a charge station, said method comprising:
- reading data from a radio frequency identification (RFID) tag on a gas cylinder said data including at least one of a hydrostatic test date of the gas cylinder, an end of life date of the gas cylinder and an operating pressure of the gas cylinder;
- and
- filling the gas cylinder with gas based on data that consists of data read from the RFID tag on the gas cylinder and from data stored in a processor of the charge station, said method further comprising using the data read from the RFID tag to determine if at least one condition of the end of life date of the gas cylinder has expired, the hydrostatic test date of the gas cylinder has expired and the operating pressure of the gas cylinder is not equal to the fill pressure setting of the charge station, and if at least one of said conditions is met, displaying a warning and/or preventing the gas cylinder being filled.
