[0019] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] See also Figure 1The crack monitor in the embodiment of the utility model includes a crack meter 100 and a self-test motor 200, the crack meter 100 is movably connected to a wire rope 110, the self-test motor 200 is rotatably connected to an output shaft 210, one end of the wire rope 110 facing away from the crack meter 100 is connected to the output shaft 210, a rope groove is provided on the side wall of the output shaft 210, one end of the wire rope 110 facing away from the crack meter 100 is connected to the rope groove, the rope groove is adapted to the wire rope 110, the stroke of the wire rope 110 driven by the output shaft 210 is 15mm to 25mm, the self-test motor 200 and the crack meter 100 are both connected to a controller 300, a self-test unit is arranged in the controller 300, a first serial port is arranged on the controller 300, the first serial port is used to output serial port instructions, a second serial port is arranged on the self-test motor 200, the second serial port is used to receive serial port instructions, and a serial port line is connected between the first serial port and the second serial port. Preferably, the steel wire rope 110 can be drawn out and retracted from the crack meter 100. When the self-checking motor is started, the self-checking unit is used to compare the reading of the crack meter 100 with the stroke length of the output shaft 210 pulling the steel wire rope 110 to see if they are consistent. When the crack monitor is working normally, the self-checking motor 200 is not started. At this time, the monitoring value of the crack meter 100 is the actual pulling value of the steel wire rope 110. When it is necessary to start the self-checking function, a self-checking instruction is sent to the self-checking motor 200 through the controller 300, the first serial port and the second serial port, and the self-checking motor 200 starts to operate. The output shaft 210 starts to rotate. Since the end of the wire rope 110 facing away from the crack meter 100 is fixedly connected to the output shaft 210, the length of the path through which the output shaft 210 rotates is the stroke of pulling the wire rope 110. Specifically, the fixed stroke length for each self-test is 20 mm. The output shaft 210 rotates 20 mm in the forward direction, that is, the wire rope 110 is pulled out 20 mm, and the output shaft 210 rotates 20 mm in the reverse direction, that is, the wire rope 110 retracts 20 mm. It can be understood that the artificial tensioning test is simulated to perform a functional test on the crack meter 100, and the self-test result can be transmitted to the controller 300.

[0024] The crack meter 100, the self-test motor 200 and the controller 300 are all connected to a power supply module 400, in which a photovoltaic power generation component is arranged. It can be understood that the photovoltaic power generation component is beneficial to maintaining the long-term operation of the equipment and is easier to maintain.

[0025] The controller 300 is connected to the wireless transmission module 500, and a 4G radio frequency unit is arranged in the wireless transmission module 500. The wireless transmission module 500 is connected to the server 600 through the 4G radio frequency unit. It can be understood that the self-test results and the readings of the crack meter 100 when it is working normally can be uploaded to the remote server through the wireless transmission module 500, which is convenient for the staff to read and manage through the remote platform, and can realize remote judgment of whether the crack meter 100 fails, and can realize regular and manual equipment self-test, which greatly reduces the safety hazards caused by untimely monitoring of geological disasters or monitoring failures. The use of the self-test motor 200 is low in cost and convenient for maintenance, saving a lot of labor.
