Hi
This past while ive been working on a PCB with an atmel microcontroller for controlling a motor and heater for an application.
I am now at a stage where i wish to monitor the process while it is running and produce a data logging facility.
Ive considered using an SD card with some type of driver on the board that will store the events as the happen on the application, this may well be the best option.
Last night i was thinking about the possibility of using DSP as the interface between the application and the data logger.
My idea is that each application in the system will produce its own unique frequency when operating. Im considering producing a device that sits on/in the application and looks for these frequencies, when one occurs the times are logged in a dedicated chip. This means that the data logger will be seperate and retro fittable (if thats a word) to any of the applications.
The main frequencies to look for are as follows:
small motor
small heater
opening and closing of magnetic switch
buzzer
Ive done some dsp stuff with Matlab in uni but now need to apply that to a real time application.
Does anyone have any experience in this type of application?, what would i use to monitor the frequencies of the application (ive heard of an accelerometer i think for condition monitoring).
Any help appreciated
