The invention provides a rail breakage monitoring method and a rail breakage monitoring device. A first ultrasonic sensor and a second ultrasonic sensor are arranged at two ends of a to-be-monitored rail section in advance and used for monitoring ultrasonic signals in a rail respectively. The method includes: acquiring a first ultrasonic signal monitored by the first ultrasonic sensor and a second ultrasonic signal monitored by the second ultrasonic sensor; judging whether the first ultrasonic signal or the second ultrasonic signal meets preset conditions or not; if at least one of the first ultrasonic signal or the second ultrasonic signal meets the preset conditions, determining that a rail breakage event occurs in the rail section. The fact that at least one of the first ultrasonic signal or the second ultrasonic signal meets the preset conditions is determined through monitoring, and the rail breakage event of the rail section is determined. The rail breakage monitoring method is simple in implementation, low in cost and low in power consumption.
Description
technical field [0001] The present application relates to the technical fields of aerospace detection and railway safety, in particular to a method and device for monitoring track fractures based on acoustic detection. Background technique [0002] With the development of the modern economy, the dependence on railway transportation is getting higher and higher, and the country's investment in railway transportation has also continued to increase. The construction of the railway network has achieved leapfrog development, and at the same time, the requirements for the speed of train operation have also gradually increased. . In recent years, my country's railways have undergone six large-scale speed increases, and the speed-up lines have reached 16,500 kilometers. While the speed of trains continues to increase, the number of trains is also gradually increasing. my country's railway traffic is still dominated by passengers and freight on the same line, and the train density r...
