Design of The Coal Seam Water Infusion Multi-level Embedded Protection System Based on Watchdog

摘要

In view of the existing automatic control system for coal seam water infusion can not work in some conditions of the mining area because of its limited anti-interference ability,in this paper we design a computer protection system composed of multi-level watchdogs. The system provides a four-tier protection measure,escalating the level of protection according to the severity of failures,when the control system hardware and software failures occur,different watchdogs start different protection measures to make the system return to normal. This design has been proved to be effective in a number of water infusion system transformations in practice.
