A method for detecting whether a point rail is attached to a stock rail is disclosed. The method is performed by using a first pressure sensor and a second pressure sensor. Each of the first pressure sensor and the second pressure sensor is configured to detect whether the point rail is attached to the corresponding one of the pair of stock rails, convert a pressure signal between the point rail and the stock rails into a voltage signal, and transmit the voltage signal to a signal processor. The signal processor is configured to process and transmit the processed voltage signal to a monitoring center having a host computer. The host computer is configured to control an operation of a switch in response to the detected pressure value collected by the first pressure sensor and the second pressure sensor by using a PID control algorithm.
