Hope all of this makes sense...
I record torque applied to bolts as part of an evaluation process of new materials. I have a rotary encoder, it pulses at 100ppr. My torque wrench gearing means 1 turn of the wrench = 1400 pulses. For each pulse from the encoder, I record a torque value derived from a 4-20mA transmitter measuring hydraulic pressure. The torque readings are saved to a csv file. There may be as many as 15,000 readings in the csv, and multiple (>300) csv files to replay. From this data plus time, I can derive torque/turn and RPM data, no problem.
I want to do some training with other operators, so can anyone recommend a system to read in my csv (SD Card) and replay it into the data acquisition system?
The electronics interface side (transmitter and pulse counter) is almost there, AD5667 DAC plus some circuitry to give 4-20mA plus an SSR to give the pulses.
Replay of the csv data is the stumbling block for me with so many options i.e. raspberry pi, beaglebone etc. The simplest option seems to be the arduino platform however it does not seem to provide sufficient memory to read the csv into an array.
So basically replaying acquired data back into the DAQ system for training/simulation purposes.
Any thoughts would be appreciated.
