Σύνοψη

The Project involves the design, construction and testing of a Data Acquisition System to be used for troubleshooting of circuit transient or 'through' faults and Sequence of Events Conditioning.
Objectives and Requirements:
1. To monitor analogue DC signals 0-20mA, 0-1 V, 0-l0V, 0-l00mV and logic signals of 0/24V DC.
2. To be fast enough to help trace the failing signal before the rest of the signals fail as a consequence i.e. high discrimination time.
3. To provide a computer interface to an IBM compatible PC which through a suitable software will be able to store input data for analysis.
4. To be able to monitor 8 measuring channels.
5. To avoid interference with the circuit under examination.
6. To develop a software program in C language for storing the input values.
7. To develop software for presenting the stored data through a Spreadsheet.
A major objective of the design and construction of this Data Acquisition System is that it may be used as a Sequence of Events Conditioning System. That is a system which will accept data from various signals from a device or equipment so that if one part of the device fails to work then through an analysis of these data anyone can detect at which part of the device the failure or malfunction took place.
Obviously in the case where the fault remains permanent, identification of the cause can easily and much more economically be achieved by simple troubleshooting procedures. However in the case where the fault is transient or happens momentarily, normal troubleshooting procedures will prove inadequate to trace the fault, as this will have already cleared itself.
The objective of this PC based Data Acquisition System is that it can be used to locate faults in devices where the malfunction occurs momentarily and then disappears having most probably caused a problem to the system it was connected to.
