Embodiment

[0043] Based on the embodiment 1, in actual application, when the intelligent human power brake fastener is used, the intelligent human power brake fastener needs to be taken out of the cabinet. When the fastener is taken out of the cabinet, the identity tag is swiped in the card swiping area. The identity tag records the corresponding worker information. The card reading module 10 transmits the worker information to the MCU 25. The MCU 25 transmits the information to the upper computer 7 through the wireless communication module 9.

[0045] During the work, the tension force is periodically detected whether it is too low or too high. The state information is transmitted to the upper computer 7 through the wireless communication module 9.

[0046] The acceleration detection submodule 18 constantly detects the acceleration offset. When the fastener body is not removed and the train departs, the movement of the train causes the fastener to move and generates acceleration. The acceleration sensor transmits the data to the MCU25. The MCU25 calculates the train displacement. If the displacement exceeds the threshold, the alarm information is transmitted to the host computer 7 through the wireless communication module 9. The host computer 7 promptly stops the train from departing.

[0047] The MCU25 constantly monitors the battery level in the power module 12. When the battery level is too low, the MCU25 transmits the data to the host computer 7 via the wireless communication module 9. The host computer 7 then prompts the worker to replace the fastener body and charge it.

[0048] When an accident occurs or the worker does not follow standard operating procedures, the voice module 16 will activate and issue a voice alarm to indicate that the fastener body is in an abnormal state.

[0049] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Therefore, all equivalent changes or modifications made in accordance with the structure, features and principles of the present utility model patent should be included within the scope of the present utility model patent application.
