SECTION 4. PRINCIPLES OF OPERATION

4.1Overall Description

The PLCHMR is a product that consists of hardware and software to provide health monitoring and remote reporting services. PLCHMR is integrated into the StrobeGuard® System. The PLCHMR uses a single board computer; manufactured by a respected industrial supplier of single board computers (SBC). The SBC provides sufficient processor bandwidth and memory support the intended health monitoring and reporting tasks. The SBC has an industry standard PC/104 bus to provide a common interface bus for a variety of off-the-shelf daughter boards. Industry standard daughter boards have been selected to provide the required input/output interfaces consistent with the demand of customer provided monitoring systems. In addition the SBC provides a 10/100 Ethernet interface and an RS-485 serial port interface. The PLCHMR will use its RS-485 serial network connection to receive and process health status data from the SGC-60. The RS-485 serial network bus will be referred to as the StrobeGuard Control and Status Network (SCSN). SCSN will be used to send commands and collect status data from each SGF-60 Flash Head connected to the RS- 485 network. The PLCHMR is collocated within the SGC-60 Master Controller enclosure.

The PLCHMR reports each flash heads’ health status via discrete outputs. Each flash heads’ discretely reported status data will be a Flash/Fail report. PLCHMR System uses a uniquely configured relay output daughter board. This daughter board drives logic inputs provide by the customer at the remote facility. The relay output daughter board will provides 8 Form C relays to report the system’s status. Screw terminals on the relay output board will enable setting the relay’s output voltage. The normally closed relay contact will be used to report the fail condition.

The PLCHMR provides an interactive character based menu -oriented Maintenance Mode Service (MMS). The MMS is accessed via the SBC’s Serial RS232 interface. The MMS is an interactive character-oriented communications session. A PC based client terminal service initiates a MMS session by logging onto the system as the “maint” user. The MMS validates the “maint” user via a password; it proceeds to establish a session with the client terminal service by initially presenting the Maintenance Mode menu.

4.1.1.1Power Supply

The PLCHMR receive 16VDC power from the Master Controllers TB8 terminal connector. The 16VDC power is fed to a single output DC/DC Converter which produces 5VDC for the SBC.

4.1.1.2Communications

The PLCHMR monitors commands from the Master Controller and Flash Head status reports via the RS485 serial link.
