UNIVERSAL DEVICE FOR RECOGNIZING PARAMETERS OF PASSIVE AND ACTIVE RADIO-ELECTRONIC ELEMENTS AND AUTOMATIC LOCOMOTIVE CONTINUOUS CODED (ALCS) SIGNALS

Abstract

The development of measuring instruments capable of performing multiple functions, handling various tasks simultaneously, and testing elements, devices, and their faulty modules helps reduce valuable repair time, ensures continuity during restrictions, improves energy efficiency in operation, speeds up decision-making, provides readily calculated results, and offers other useful features. The distinguishing characteristic of such devices compared to others is their reprogrammable nature, which allows them to be adapted and enhanced for specific applications and industries. Such universal instruments are widely used in specialized fields of technology. Therefore, this article focuses on the modernization of transistor testers through both software and schematic approaches. The proposed device enables the measurement of the values and pin configurations of active and passive components, measurement of DC voltages, detection of frequencies of simple and pulse-width modulated signals, and transmission of pulse signals. Additionally, it allows for contactless detection of ALS (Automatic Locomotive Signaling) coded signals on railway automatic block sections, thereby determining the operational status of those sections.
