摘要
The subject of the invention is a method and a device for monitoring digital signals generated in electric power meters working in substation automation control systems, which meters are a source of a digital signal containing current and voltage values measured in primary circuits. The invention is characterised in that in a communications port (10) sampled digital signals sent by at least one electric power meter are received in the form of network packages which are then transmitted to a network package analysis module (101) and farther via a signal decoder module (103) to a visualisation table register module (104). In a signal analysis module (106) a signal visualisation retention mark is calculated on the basis of data from the visualisation table register module (104) and a retention criterion which is supplied from a control module (107), and the statistics of the signal of electric power meters is calculated. The data from the visualisation table register module (104), the signal analysis module (106) and the control module (107) are transmitted to a display control module (105) wherein the content of a display (9) is automatically formed in real time.
