Huaxia College of Wuhan University of Technology course Course title Cheng set up meter Microcomputer interface technology and Application order Professional class number, name, performance guidance, teacher Specific date Course design task book Design topic: traffic lights real-time control system design and design purposes: 1., consolidate and deepen the knowledge learned in the classroom; 2. design methods of learning and mastering the hardware and software of computer control system and the ability to access and use information; 3. in the TDN integrated development environment to achieve the design and production of traffic lights in the real-time control system, the integrated use of 8259, 8253, 8255 chip, can understand and master the use of the principle and method of programming 8255A control. Design tasks: within the specified time to complete the following tasks) 1. draw the hardware principle diagram (interface chip and peripheral part, traffic lights and intersection relationship) and the connection map; 2. traffic lights control mode is the four intersection traffic turns (no intersection traffic control mode (step) see table B);; the intersection traffic to allow traffic by allowing yellow light flashing 5 seconds; 3. with a 2 bit 7 LED digital tube display the countdown time of traffic intersection. *4. each intersection is allowed to open within the time, if there is an abnormal event (using the switch analog interrupt signal generation), then all the lights blink for 10 seconds, returned to its place to continue. Time arrangement: June 21st June 22nd ~ June 24th June 25th layout problem, determine the hardware design task, to find relevant information, function analysis, draw up the experimental circuit, programming, debugging and running system; defense design report.
