Problems solved by technology

Because the umbilical cable that is too short cannot achieve the purpose of placing the wading robot to the predetermined depth, and the umbilical cable that is too long not only increases the self-weight of the wading robot and consumes too much power of the wading robot, but also may cause damage to the umbilical cord. The entanglement of cables and underwater obstacles brings danger to the navigation of wading robots

Embodiment 1

[0044] like figure 1 and figure 2As shown, the embodiment of the present invention proposes a cable control system for a wading robot, which is used to control the retraction / release of the cable, including a drive control part and an execution part electrically connected, and the drive control part It includes a controller 5 and a driver 3 that are electrically connected. In this system, the base station of the wading robot floats on the water surface or is installed on the ground, and the wading robot and the base station are connected by cables, and at least the motor 4, the roller 21 and the angle sensor 7 in the execution part are installed on the on the base station.

[0045] The controller 5 is electrically connected to the depth measuring device on the wading robot, and the depth measuring device sends the underwater depth value of the wading robot to the controller 5 . The controller 5 first sets the depth value as the length of the cable that should be released a...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that in this embodiment, the controller 5 calculates the target value of the motor rotation angle according to the length value preset by the user. The preset length value is fixedly set in the controller 5 by the user before the wading robot is launched into the water, so as to realize the automatic retracting / releasing operation of the cable when the wading robot is sailing at a fixed depth.

Embodiment 3

[0056] The difference between this embodiment and the above embodiments is that in this embodiment, the controller 5 calculates the target value of the motor rotation angle according to the length value input by the user. In this embodiment, the length value is input by the user's control terminal, and the control terminal includes but is not limited to a control terminal with an input device wired to the controller, or a wireless input terminal / terminal that communicates wirelessly with the controller. Tablet PC / smart phone / remote controller (at this time, a wireless communication module is arranged in the controller, and the communication with the wireless input terminal and other devices is realized through the wireless communication module).

Abstract

The invention discloses a cable control system and a cable control method of a wading robot. The cable control system comprises a driving control part and an execution part which are electrically connected. The driving control part comprises a controller. The controller is electrically connected with a depth measuring device on the wading robot. The execution part comprises a motor, a roller driven by the motor to wind / unwind a cable and a feedback device used for feeding back length information of the cable actually wound / unwound by the roller. The controller controls winding and unwinding operation of the cable according to received depth information transmitted by a depth measurement device and the length information, fed back by the feedback device, of the cable which is actually woundand unwound. The control system can conduct accurate cable winding and unwinding control according to the depth of the wading robot, so that the cable length is effectively utilized to the maximum extent, the situation that the wading robot drags an overlong umbilical cable during movement is avoided, and the wading robot operates more efficiently.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a cable control system and a cable control method of a wading robot. Background technique [0002] The wading robot applies artificial intelligence, detection and identification information fusion, intelligent control, system integration and other technologies to the same underwater carrier, and completes geological and topographical tasks without manual control or manual semi-automatic control. probing. Since underwater electromagnetic signals attenuate relatively quickly, wireless signals cannot be transmitted underwater, so the current wading robot system will be equipped with a base station for wired connection with the wading robot. Therefore, when the wading robot moves or performs operations underwater, it will drag the umbilical cable connected to the base station. [0003] In order to improve the maneuverability of the wading robot and reduce the useless load o...
