Embedded type system-based control device for horizontal directional drill

Abstract

The invention relates to an embedded type system-based control device for a horizontal directional drill, which comprises an orientating instrument, an embedded type system and a programmable logic controller, wherein the orientating instrument is used for obtaining current drill bit position information and feeding back the drill bit position information to the embedded type system; the embedded type system is used for automatically planning the operation track of the horizontal directional drill, correcting the deviation of the operation track according to the drill bit position information fed back by the orientating instrument, transmitting a control instruction to the programmable logic controller, receiving a data packet of working condition information of the programmable logic controller and displaying the working condition information to operation personnel; and the programmable logic controller is communicated with the embedded type system through a CAN (controller area network) bus and is used for driving the horizontal directional drill to operate and monitoring the working condition information of each part of the horizontal directional drill. With the adoption of the control device, the automatic track planning and deviation correction of the horizontal directional drill are realized, the operation mode of the horizontal directional drill is simplified, and the working efficiency and the quality are improved.

Description

technical field [0001] The invention relates to a control system mechanism of a horizontal directional drill, belonging to the technical field of control of the horizontal directional drill. Background technique [0002] Horizontal directional drilling is a kind of engineering machinery used to lay various underground facilities, such as pipelines and cables, without excavating the ground surface. This construction method not only saves costs but also reduces environmental damage. The development of domestic infrastructure has promoted the application of horizontal directional drilling, and at the same time put forward higher requirements for its automatic operation level. At present, the operation of horizontal directional drilling is mostly done manually, and the operator needs to complete the construction process according to his own technical level and experience, which is labor-intensive and low in efficiency. Therefore, it is an urgent problem to be solved to improve ...

AI Technical Summary

Problems solved by technology

Although the above scheme can achieve real-time positioning and deviation correction adjustment in the horizontal directional drilling process to a certain extent, the closed-loop monitoring system based on the industrial computer software platform not only has high cost, but also has difficulty in reliability under harsh working conditions. Guarantee; on the other hand, the steering instrument used on many horizontal directional drilling itself is a closed system, and it is not feasible to directly connect its sensor output to the analog input module on the PLC, even if the two can be connected , it is not the best solution for the PLC to collect data from the guide device and then communicate to the industrial computer through RS232
