Embodiment Construction

[0028] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0029] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "u...

Abstract

The invention discloses a train bearing fault detection and warning system, characterized by comprising a first train bearing fault detection device, a second train bearing fault detection device, a first wireless geomagnetic sensor, and a second wireless geomagnetic sensor. When passing of a train is detected by the wireless geomagnetic sensors, information of the incoming train is transmitted tothe train bearing fault detection devices installed on two sides of a rail; the train bearing fault detection devices are activated in operating state, microphones on the train bearing fault detection devices receive sound produced by train bearings, the sound is analyzed, laser sensors on the train bearing fault detection devices count wheel pairs, and when damage of bearings on one pair of wheels on the train is detected, damage information is transmitted to a dispatching center through GSM (global system for mobile communications); better detection effect is provided, and manual detectioncan be replaced effectively.

Description

technical field [0001] The invention relates to automatic detection and wireless communication equipment, in particular to a train bearing fault detection and alarm system. Background technique [0002] The train is the vehicle with the largest transport volume on land, which effectively drives the economic development of the country and the region. However, due to the long-term heavy load of the train bearing, it is easy to have surface peeling, fatigue, cracks and other failures, which seriously affects the safety of the train. . [0003] Fault diagnosis at the present stage mainly relies on manual inspection, shaft temperature alarm and other methods for detection, that is, workers rely on experience to judge faults. This method has a high misjudgment rate and cannot perform accurate detection. The shaft temperature alarm is to judge the temperature of the bearing and realize online detection. This method is simple and practical, and has a good discrimination effect fo...
