Electronic Product Code Reader (EPR The following description is about an Electronic Product Code Reader (EPR) which is used for reading the passive RFID tags and show the Electronic Product Code (EPC) values. You are required to analyse and design the requirements of the EPR (Figure 1) given below according to the 8051 microcontroller specifications. The MC needs to show the EPC value on an LCD display. A keypad can be used to start/stop the system and other operation where necessary. There should be a mechanism to detect the vehicle before it enters to readable area and automatically activate the tag reading process. State all other a f any) when ansvw Q1] (i) For the proposed mechanism, identify suitable ensors and actuators to detect a vehicle prior to arriving at readable area. RFID Antenna Passive RFID Tag RFID Module (RM) (ii) Draw a diagram to show, how to detect the arrival of a vehicle at the readable rea LCD 8051 (MC) Keypad (ili) List four (4) features required in a microcontroller for this application and provide proper justification for each. [Q2] (i) Draw the extemal view of the system, ie A diagram that shows the inputs/sensors and the outputs/actuators of the system. (ii) Draw a diagram and show how to interface RM with MC. Clearly show all the Figure 1: Typical view of EPR signals. iil Identify the sub units/sub modules of the system and draw the interconnected Figure 1 shows the major components of the EPR The EPR consists of a RFID module (RM) which is connected to the RFID antenna, a LCD, a Keypad and 8051 microcontroller (MC). The RM consists of Start of Reading signal (SOR), End of Reading (EOR) signal, and DATA buffer (char (24)). The MC needs to send low to high pulse to the SOR in order to activate reading the RFID tag of a vehicle. Once the SOR signal has been sent, The MC needs to wait until the EOR signal becomes available to read the tag data (EPC). The EOR signal will change high to low after the RM reads the RFID tag of the vehicle and ready to send the tag data (EPC). After the EOR signal becomes available, the MC can read the RFID tag data from the DATA buffer of the RM via serial communication A pasive RFID tag includes EPC memory banks, which holds te char (24) EPC code (Ex. 3575BCD15BC614E000000001). block diagram of the system using the central controller and other required interfacing devices. Q3] Draw a schematic diagram of the system. Clearly show each electronic components/module. Use any suitable software tools to create a schematic diagram. [Q4] Draw flowchart(s) to represent the algorithm of the EPR operation. Clearly show the port mapping of the 8051 microcontrollers.
