- Continue progress report with do research on methodology parts.
Objective
- To description on the opproach meterials and produce used identification on the limitations range of validity and assumptions employed.
Content
- This section contains an overall description of the research approach meterials and procedures.
- The diagram in figure above shows the process overall system that is capable of the Intelligent Fire Fighting System.
- The controller unit is based on micro controller. It controls all the blocks. The unit has a thermocouples to sense the different temperatures, which are fixed in circular path at equal 45 degree, in up and down positions.
- The thermocouple sensors are connected to signal conditioning unit. The sensor produces
low voltage signals (in terms of few milli-volts), which cannot be measured by ADC. Therefore
the weak signals are amplified to 0-5v level by signal conditioner unit. Maybe I'm using ‘K’ type
thermocouple, which has low non-linearity error.
- The output of the signal conditioner is fed to the analog to digital converter (ADC). The ADC has capable of measuring 8 channels and the resolution of 8 bits. The 8 channels are
used to measure the room temperature at different points. One 5-digit seven-segment display
is used to indicate channel No. & temperature.
- A stepper motors drives the robotic arm. One stepper motor is used to rotate the water gun in circular motion and the next one is for to move vertically.
