Temperature monitoring system is designed to
collect the temperature data from eight different
equipments positioned at different sites and send
it to a single redundant host system consisting of
main and standby systems, thereby providing an
interface between external devices.
 Can be used in an area where wide variety of
equipments have to be connected to a single
monitoring unit.

 It has a host-end redundancy technique for doubling
the equipments from 8 ports to 16 ports.
Host system
 This consists of mainly 2 systems, the main system
and the stand by system.
 This is the interface unit, called the Temperature
Monitoring System, in short TMS unit. It receives the
temperature information available in various formats
and protocols periodically, from different systems
(temperature channels) like Rugged VME chassis,
Rugged Flat-Panel Monitor and Routers.Equipments
are observed here.
 The equipments are the different type of systems

ARCHITECTURE :
Working Principle
Equipments whose temperature is to be monitored are
connected to the TMS unit.
Equipment is linked to the TMS unit at DUART’s
section. DUART
section consists of 4 DUART’s, as each DUART can
handle two equipments thus giving provision to connect
8 equipments.
The heart of the TMSC board is the microcontroller
89C52, as it plays the vital role of controlling all the
operations inside the board.
The data collected at the DUART’s may be of different
formats, which is converted by the microcontroller into a
particular format understood
Level converters are used to convert the standard RS-232
port levels of the serial ports to TTL. An EPROM and two
RAM’s are interfaced external to the microcontroller for
future use when expansion is required,
The XTAL1 and XTAL2 are used to generate clock pulses by
which all internal operations are synchronized .The crystal
frequency used here is 11.0592MHZ for micro controller and
3.6864MHz for DUART
TMS indicator glows in red/blue/yellow indicating the internal operation of the TMS unit as indicated below
1.Glows in red color while collecting temperature data from equipment.
2.Glows in green color while sending the temperature information to the host.
3.Glows in yellow color while doing internal operations.
 Full-featured source code editor,
 Device database for configuring the development tool
setting,
 Project manager for creating and maintaining your
projects,
 Integrated make facility for assembling, compiling, and
linking your embedded applications,
 Dialogs for all development tool settings,
 True integrated source-level Debugger with high-speed
CPU and peripheral simulator,
 Advanced GDI interface for software debugging in the
target hardware and for connection to monitor-51.
 Call ‘Initializing’ function.
 Repeat the following steps continuously for ever.
 Check for system receive flag.
 If it is true, call system response function.
 If command is ready go for ‘Restart’ function.
 Read ‘Router’ function.
 Call ‘System’ function
 Future Scope
 The future upgrade is to tie this system into the
master fiber-optic wide area network when the
network goes into service and to provide a link to the
Programmable Master Supervisory Control (PMSC)
system when delivered. Measurements can be made
remotely up to several kilometers via FO cable.
 The PC monitor will be able to preserve the received
immediate message. Then, it extracts and analyzes
the historical data to provide a scientific basis for
control strategy.
