Real Time Datalogging with Java

hi guys,

we are currently developing a monitoring system for a motorcycle dynamometer. the dynamometer was a conversion from an engine to chassis. some of the parts particularly the analog sensors, we just retained from the system; the torque sensors and the rpm meter were all made up from dials.

the dilemma here is that we need to convert the analog sensors into digital ones, (i'm thinking of using tranducers..) moreover the system should log the torque and speed respectively. for this we had the ff concept:

[2sensors;for torque & speed]-->[amps]-->[2 adc]-->[mux2x1]-->[8051 or PIC?]-->[to RS232]

basically it a datalogger concept or an ADC

Q:
1. is it possible to log data on a PC using the our concept above?
2. is it possible for real time datalogging?
3. can we use Java Software as a datalogging sw? can it read rs232?
4. pls. give us more detailed schematic of a datalogger or any links/documents


thanks a lot in advance..

Hi Chichard

Answer :

1) Yes ,but you have to save the data on the 8051 board first using a Dataflash memory of Flash card memory and then download it to PC

2)Yes the 8051 can do realtime data logging, you can use the F type {8051Fxxx}
from siliconlab for fast data logging

3)Yes , you can use JAVA as your interface software who run on PC computer

4)search w*w.google.com for datalogger + schematic and you find a lot .
