Method for troubleshooting communication fault between superordinate computer and subordinate computer for pumped storage power station online monitoring system
By detecting the lower-level machine's numerical display, network connectivity, and signal reception status, the communication faults between the upper and lower-level machines in the pumped storage power station's online monitoring system were investigated layer by layer. This solved the problem of low accuracy in communication faults after long-term operation, and enabled efficient and accurate fault location and handling.

Abstract
The present application relates to a method for troubleshooting a communication fault between a superordinate computer and a subordinate computer for a pumped storage power station online monitoring system. The method comprises: when there is a communication fault between a superordinate computer and a subordinate computer, detecting whether numerical value display of the subordinate computer is normal or not: when the numerical value display of the subordinate computer is normal, detecting network connectivity between the superordinate computer and the subordinate computer; when the network connectivity is normal, detecting network configuration conditions of the superordinate computer and the subordinate computer, the network configuration conditions comprising setting conditions of gateways and subnet masks of the superordinate computer and the subordinate computer; when the network configuration conditions are normal, simulating the function of the superordinate computer by means of a test device, and detecting a signal receiving state between the test device and the subordinate computer, the test device being connected to a photoelectric switch of the superordinate computer or the subordinate computer; and on the basis of the signal receiving state, determining a fault troubleshooting result of a pumped storage power station online monitoring system. By using the method, the accuracy of communication fault troubleshooting can be improved.
