Abstract

A chemical monitor interface is generally comprised of three identical ciit boards each linked together through fiber optics. One of the circuit boards is electrically connected to a Chemical Agent Monitor (CAM), an off-the-shelf product, while another circuit board relays control information to the first connected to the CAM. A third circuit board relays only visual status to an observer by using a plasma display, while the first two boards can also control the CAM as well as display status. The interface allows the CAM to run without human intervention, thus allowing the U.S. Naval Fleet, and other U.S. military field units, to meet a need for remotely detecting life-threatening chemical attacks without harm to personnel. The chemical detector is able to purge itself of chemical agents and is immune to shock, vibration and radiations such as EMI.

Claims

1. A chemical agent monitor control interface system comprising:

a chemical agent monitor;

means for inputting serial data from said chemical agent monitor;

means for outputting electrical control signals to said chemical agent monitor;

means for fiber optically linking control and status signals within the system;

a purge valve connected to said chemical agent monitor for purging said chemical agent monitor whereby said monitor can be purged remotely by manual or automatic control;

means for processing to provide programmed control of said chemical agent monitor and said purge valve; and

means for outputting display data from said means for processing whereby operators can discern the system status and any chemical hazard detected by said chemical agent monitor.

2. A system according to claim 1 further defined by an audio alarm whereby an alarm sounds when a chemical hazard is detected by the system.

3. A system according to claim 1 further defined by switching means for selecting between local and remote control of the chemical agent monitor.

4. A system according to claim 1 constructed with integrated circuits.

5. A control interface system for a chemical agent monitor and advisory system comprising:

means for inputting serial data from a chemical agent monitor;

means for processing the data received from said means for inputting;

means for outputting human-readable display data from said means for processing;

means for displaying continuous chemical and system status received from said means for processing at a plurality of locations in human readable form;

means for sounding an audible alarm when the data inputted from said means for inputting indicates a chemical agent is present;

a purge value activated by means for processing whereby the chemical agent monitor inputting to said means for inputting can be remotely purged, manually or automatically, through software; and

means for manual control whereby the chemical agent monitor can be operated manually from a remote site.
