Abstract

Abstract

To address the issues of low integration, lengthy on-site commissioning cycles, and inefficient fault localization in conventional electric control systems for coal mine drilling rigs, a digital direct-drive electro-hydraulic control system for coal mine drilling rigs is designed. A distributed architecture is adopted, and a dual-channel isolated CAN bus communication network is constructed. Data service and edge computing modules, multi-source heterogeneous data acquisition boards, and digital valve-based drive circuits are developed. A dedicated communication protocol is established, along with algorithms for bus online monitoring, sensor fault diagnosis, and variable-triggered control command transmission. Remote networking and IAP remote upgrade technologies are integrated to enable remote system commissioning and maintenance. The system is applied to various types of mine drilling rigs. Compared with traditional electro-hydraulic control systems, the average commissioning cycle is shortened by approximately 50%, the fault identification rate for conventional electric control systems under non-power-short-circuit conditions reaches 100%, and after-sales service frequency is reduced by about 50%. This study effectively enhances the digitalization level and system maintainability of electrically controlled drilling rigs, offering a feasible solution for the digital upgrade of mining drilling rigs.
