Gas cylinder monitor and control system

摘要

A system for monitoring and controlling distributed functions within a building, such as the pressure and temperature of gases stored within cylinders. A plurality of modules are located at strategic points within the building for performing specific allocated functions in relation to monitoring and controlling the status of the gas cylinders. A first type of module detects dangerous conditions within the gas cylinders and generates and displays alarm signals in response thereto. A second type of module displays the alarm signals at a location remote from the gas cylinders and transmits command signals for remote shut off of a predetermined one or more of the gas cylinders. A central module interconnects each of the first and second modules and controls signal transmission therebetween. A communication module is connected to the central module for transmitting alarm signals to an operator remote from the system in order that the operator may become apprised of the status of the gas cylinders and take any necessary action.
