Optimal reform of safety circuit and upper computer in auxiliary shaft hoisting system

  • In view of shortages in hardware and software of safety circuit and upper computer of coal mine auxiliary shaft hoisting system, optimal reform was applied to the system. Experiment method of over wind was improved, signal of brake system emergency stop was introduced to the safety circuit, and state signals of each node of the safety circuit were introduced into RSView32 human machine interface, so as to display state of the safety circuit in real time. According to requirement of site maintenance, function of reset display and alarm signal of big stroke deviation were added to the upper computer. The actual application shows that the optimal reform can locate fault node rapidly and realize inter-checking between the hardware and software.
