Figure 5.4-1: Diagram illustrating the flow chart control box unit.
For the control box unit there will only be input coming from the hand held unit
which is the calculated BAC value. There will be a module that will be able to test
and see if this is a valid value for the car to be able to start. This module will be
named ingite_d. This module will be able to debug all the data that has been
received and able to determine the state of the control box unit. The calculated
BAC value determines the state of the control box unit. Given that, it is very
important to make sure that the validation is not failing. With the ignite_d module,
it will be able to check the information that has been received from the hand held
unit. Furthermore, since the control box unit has access the vehicles relay, it will
be highly important to check and see that the bus line is active when it is
supposed to be. The module that will be used for this is called sysStat_d. This
module will be able to get information on the system and to check and see if the
lines that are connected to the MSP430 are active or deactivated. Just as
mentioned before it crucial to detect any defects in the system. If there is no way
to detect procedure, the system will fail at any type of interference.
5.5 System Test Procedure
It is imaginable that all testing equipment has the sole purpose of outputting a
correct and accurate result for whatever it desires to sample. Our product is no
difference. It is same in a way so imperative that professionally, it is the key to
get governmental approval or not. It is so crucial that accuracy will be the sole
reason for the customers to want to purchase the product and ultimately decide
