Method for collection, selection and conversion of measurement data enabling diagnosis of electricity devices, especially in industrial plants and a concentrator for applying this method

摘要

A method for collection, selection and conversion of measurement data enabling diagnosis of electricity devices, especially in industrial plants, comprising transmission of measurement results from various meters, cooperating with different receiving devices of electricity, to corresponding inputs of a concentrator, pre-processing the results and converting collected data to one standard, and sending the data to a database using conventional transmission standards, which is characterized in that in the first cycle, comprising setting of an operating parameter range, the concentrator identifies a normal operating state of the respective devices included in the energy network, and next writes into a memory the obtained information about this operating state, while in the next cycle the concentrator compares this obtained information with parameters of the current operating state of the device and sends an alarm signal to an output of the concentrator only when it detects deviations of operating parameters in relation to the range of parameters set in the first cycle, thereby reducing the load of a transmission medium. The present invention also relates to a concentrator for collection, selection and conversion of measurement data enabling diagnosis of electricity devices, especially in industrial plants, comprising a processor, an input module, a filter and an output buffer, which is characterized in that it further comprises a device state identification module (4) adapted for identifying an operating state of receiving devices included in the energy network and writing into its memory obtained information about this operating state.
