The purpose of this project is to build a model of railway automatic control with barricade PLBs controller. Get the efficiency of that set. Project guideline to the performance.And the LDR for detecting objects beside the tracks before the intersection of the street with a ตามที่กำหนด tracks and railway barrier control box installed in the drawer. When the model trains arrive sensor will send signals to theIn order to motor rotation beam guard rail down and lifting beam barrier. When passing through the sensor. This system can build up can work in the introduction. System key, created a system with cheap. The device can find out the domestic buyerThe efficiency model of railway project barriers automatic control with micro controller P in = P out results ten times more of the sensor has 100%.
