| Abstract: | According to the requirements of the crossroads traffic lights control, the PLC design is used to achieve the sequential control of the normal transportation, through the sensor to complete the intelligent distinction and processing of the abnormal traffic conditions. In the design of the system, one method of intelligent control is used which combines the Programmable Logical Controller and the Sensor, uses the shaft-type sensor to gather vehicles pulse and the high speed counter of the PLC to count the nu... |
