Q.5 An embedded system for a packaging plant in an industry has to be designed which is controlled by a centralized embedded system (the centralized system need not be designed). The industrial complex is automated in a distributed manner due to the large number of products. The requirements of the packaging plant system are listed below: - The packaging plant is situated in a remote area of the industrial complex - The central embedded system and the packaging plant embedded system communicate only via wireless means. - The bandwidth of the wireless channel is 2 kbps. - Maintenance of optimum temperature inside the packaging plant should be the crux of design. - The temperature monitoring requires use of five (5) different temperature sensors placed at different locations in the packaging room. - The temperature sensors give an analog output ranging from 0V to 4.5V depending upon the temperature in the room. - At each corner of the packaging room four large fans are provided to control the temperature. The speed of the fan is dependent upon the room temperature. When the temperature increases the speed of the fan increases accordingly and viceversa. The frequency of the input waveform to the driving circuitry of motor should 5KHz with 85% duty cycle. - The temperature in the room should be sampled every 10 second and sent to the central system after calculating its average. - The average temperature should also be displayed on a two digit seven segment LED inside the room. - Only the centralized embedded system decides the type of package and the time of packaging a particular product. - When a product changes, the centralized system transmits the product type to the packaging plant. 5.1. List the various units of 9S12C32 that will be used for controlling the packaging plant. 5.2. Give the complete block diagram showing all the internal modules that you are 5.3. 5.4. State the purpose and justify the choice of various units you have selected.
