Railway switch closing force detection method and system

The invention discloses a railway switch closing force detection method and system. The method comprises the following steps: acquiring an acting force between locking iron and a locking frame by virtue of a closing force sensor, forming a charge signal, and transmitting the charge signal to a circuit conversion module; controlling the circuit conversion module to convert the charge signal into anelectrical signal and transmit the electrical signal to a transmission unit; controlling the transmission unit to transmit one or multiple electrical signals to a control unit; and converting the electrical signal(s) into a closing force curve by the control unit. The system comprises the closing force sensor, the circuit conversion module, the transmission unit and the control unit. The method and system which are disclosed by the invention directly reflect closing forces between a switch rail and a stock rail and between a point rail and a wing rail, the system is easy to mount and adapts to an outdoor switch envir
