Collector 211 can collect the detection data of detecting element 10 to wire rope 30, and when wire rope 30 appeared damaging or cracked the condition, collector 211 sent the signal for alarm 212, and alarm 212 will report to the police.

Further, a thermostatic dehumidifier 214 can be further arranged in the data acquisition conversion workstation to protect the detection unit 10 and the collector 211, so that the problems that the detection unit 10 and the collector 211 are invalid or the accuracy is reduced due to overhigh temperature or humidity are avoided.

It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
