Problems solved by technology

The sensor is connected to the steel wheel and other joints, and it is bound to follow the wheel and receive relatively frequent and irregular vibrations. If the process is not handled properly, the sensor is easy to fall off or be damaged due to vibration
In addition, psychologically, users are not willing to add additional equipment, which will bring additional costs

Embodiment Construction

[0023] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0024] The purpose of the present invention is to realize the judgment of the forward and backward movement of the locomotive without changing the wheels of the locomotive or the surrounding parts. On the basis of the positioning hardware equipment of the locomotive dispatching system, an electronic compass is added, and the combination of GNSS technology and electronic compass technology is used to achieve the purpose of judging the forward and backward of the locomotive. Since the electronic compass is added to the GNSS positioning equipment of the original dispatching system, the structure of the locomotive will not be changed. Compared with the past, it is more convenient and practical. One device that meets the user's requirements can realize the needs of multiple functions without adding external sensors.

Abstract

The invention discloses a locomotive running direction judging method and a device thereof. The method comprises the following steps: S1, judging whether a compass is corrected or not, executing S2 if so, and correcting the compass and executing the S2 if not; S2, acquiring the included angle delta between a locomotive head and the compass; S3, acquiring the course angle beta of the locomotive head and the deflection angle alpha of the compass; and S4, judging the value of |alpha - beta| is equal to |180 DEG - delta| or not, judging that the locomotive head goes backward if so, and ending the flow if not. The judgment of advancing or backing of the locomotive is realized without changing the wheels or circumferential parts of the locomotive. The electronic compass is arranged on the basis of a locomotive scheduling system positioning hardware device, and a GNSS technology is combined with an electronic compass technology to realize the judgment of the advancing or backing of the locomotive.

Description

technical field [0001] The invention relates to a method and a device for judging the running direction of a locomotive. Background technique [0002] Now in the field of construction machinery, projects are getting bigger and bigger, and human management alone is becoming more and more laborious. Most of the large-scale construction machinery projects have been managed by the automation platform, so as to improve the efficiency of project management. In construction machinery project management, it involves positioning and tracking management of construction locomotives to achieve optimal task allocation and scheduling. In the locomotive tracking process, judging the forward and backward of the locomotive is one of the tasks. In the previous schemes, the recognition of the forward and backward of the locomotive was achieved by judging the steering of the wheels. This method uses an additional sensor device (grating sensor, Hall sensor, etc.) on the wheel or its power con...
