My DB-Con Poster

Figure 33: DB-Con Poster

This is my last post present the poster that I'm going to present for my fyp demo (24/04/2012) ^_^ Thank you...

Results

1) Activate the system

Figure 25: Prototype System

Figure 26: LCD display upon activating the system

Figure 27: LCD display upon GSM Modem is ready to operate

Figure 25-27 shows the system prototype and LCD display when the system is activated and ready to operate. The prototype is activated when the 9Vdc power is applied to the control board and 6Vdc power is applied to the GSM Modem.

2) 1st RCCB Trip

Figure 28: LCD display upon Earth Fault occur

Figure 29: SMS receive upon the trip condition

Figure 28 and 29 shows the LCD display when an earth fault has occurred and trip the 1st RCCB. The system sends a SMS to the user to report the tripping and reply command to switch on the Backup RCCB.

3) Backup RCCB Triggered

Figure 30: User SMS Reply Command

Figure 31: LCD display upon switching on the Backup RCCB

Figure 32: SMS receive upon the Backup RCCB successfully energize

Figure 30-32 shows the SMS reply from the user to switching on the Backup RCCB. When the Backup RCCB successfully triggered, LCD will display “B.RCCB TRIGGERED” while at the same time GSM Modem will sends SMS to the user to inform the status of Backup RCCB.

In the above figure, it shown the wiring design for DB-Con distribution board.

Control Board Circuit

Overall from the previous posts, they together create a complete control circuit to monitor the 1st RCCB situation and turn on the Backup RCCB when the 1st RCCB trip.

ICSP: In-Circuit Serial Programming

In-System Programming (ISP) is a technique where a programmable device is programmed after the device is placed in a circuit board. In-Circuit Serial Programming (ICSP) is an enhanced ISP technique. ICSP (In-Circuit Serial Programming) mode is special programming protocols that allow read and write to PIC Microcontroller and is the most direct method used to program the device. The ICSP capability is microchip’s proprietary process for microcontroller programming in the target application. The ICSP interface uses two pins as its core. The programming data pin (PGD) functions as both an input and an output, allowing programming data to be read in and device information to be read out on command. The programming clock pin (PGC) clocks in data and controls the overall process.

Serial programming allows customers to manufacture boards with unprogrammed devices and then to program the digital signal controller just before shipping the product. Serial programming also allows the most recent firmware or a custom firmware to be programmed.

Figure 19: ICSP Connector

PGD - Data: usual port and connection RB7

PGC - Clock: usual port and connection RB6

RESET: for the reset input

These are the signals that do the work. Data (PGD) and clock (PGC) transmit data to the pic micro. First data is sent either high or low voltage (0/1). After a suitable time the clock is strobe low to high - rising edge clocking the data into the microcontroller. PGD is also the line driven by the pic micro during verify i.e. it is bi-directional.
