Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0023] In order to solve the above technical problems, the present invention proposes a power control system for a logging device. In order to overcome the power shortage caused by the limited space of a single traction device, the power control system of the present invention includes at least two traction devices, such as figure 1 As shown, the power control system includes a control device 2 and at least two traction devices 1 . Wherein, the at...
