Description
Modify an existing circuit design and electronic code to be more robust.

DC supply of 24vdc +/- 50v Powering a PIC chip that has a square wave signal input 0-125hz from an open collector hall effect transistor that has 5-24vdc 12vdc nom input from the circuit board.

When the frequency reaches 17hz for 4 seconds turn on a relay and led and wait 1 hour then turn the relay off. If 17hz is reached for 4 seconds again reset timer. Rough source code attached.

A current circuit design will be attached as well. Items to be added to the design will be
1. Some lighting protection
2. Reverse polarity protection
3. Different Voltage regulator setup to facilitate operation of the circuit below 50vdc
4. Current limit of 3a to the relay controlled dc output.

Product will include a cad drawn schematic, new parts list, and new source code. If I am missing anything important please pm me.





Additional information: Submitted on 12/18/2008 at 21:49 EST

The dc supply voltage is 24vdc nominal and never more than 50vdc.


Additional information: Submitted on 12/18/2008 at 22:02 EST

Attached are the component descriptions for the circuit diagram.

I would like to Build this device. The device robustness will improve (> 200% estimate) because of following improvements. It will have a schmitt trigger added between the Hall Effect Anemometer (0-125 Hz) and PIC16F684. Also the PIC16F684 software will be written to include interrupts for the counter of 17 Hz such that if the input frequency is above that it will not waste timeout period of four seconds. Another improve will be to have a 10 Millisecond timer to sample the incoming frequency. The PIC16F684 clock will be set to run at 8 MHz to improve system response. Once 17 CPS has been sampled for four seconds the power relay will be energized and the PIC16F684 will power down for 1 hour to conserve power. Upon 1 hour timeout the PIC16F684 will wake up and repeat the 17 Hz sampling in 4 second period window. A 5 VDC (78L05) regulator will be changed to accommodate lower input power of 40 VDC. A reverse polarity device will be added to protect against hooking up incoming power in reverse manner. A lighting surge device will be placed between incoming unregulated power and the output of the 5 VDC regulator. This should add about 15 Kv ESD protection. Delivery of CAD drawn schematic(s), Bill of material(s) of parts from major manufactures (DIGI KEY, JAMCO electronics and others) and all source code will be provided 21 days upon bid award. Payment of 50% + getacoder fee (approx $100) upon bid award shall be due. Remaining payment due when device is received by Project Creator RabidRhino. Thank you, CPU8052
