The invention discloses a monitoring system for railway track bolt looseness. The monitoring system comprises a laser emission module, a track fiber, a cutting device, a laser receive module and a processing circuit module. The processing circuit module comprises an electromagnetic relay, an alarm circuit module and a control circuit module used for controlling a railway track system. The cutting device is used for cutting off the fiber when a bolt loosens. When the railway track bolt loosens, the cutting device cuts off the fiber, the laser receive module can not receive a light signal, so an alarm is given; meanwhile, a railway track relay circuit is cut off. The invention further discloses a monitoring method for railway track bolt looseness. According to the monitoring system and the monitoring method for railway track bolt looseness, the looseness condition of the railway track bolt is systematically monitored in real time; in addition, the design process and the manufacturing process are simple, the price is low and large-scale manufacturing and application are facilitated.
