Computerized System for Remote Level Control with Discrete Self-Testing

This article describes the functional structure, human-machine interface as well as software and hardware means of a computerized system for remote control of liquid level with discrete self-testing implementation. The system has a hierarchical structure in which information processing is decentralized, and software and hardware components are removed from each other. The proposed by authors method of self-testing of hydrostatic sensor correctness, that generally increases system reliability, is considered in detail. Resulted system is then tested on computer simulation and experimental setup.
