DEVICE FOR CONTROLLING MOTOR DRIVES OF CONTACT NETWORK DISCONNECTORS Russian patent published in 2006 - IPC G08C19/28 

FIELD: engineering of information-controlling complexes for automated systems for controlling electrified portions of railroads.

SUBSTANCE: control commands are represented in form of coordinates - positional (distributive) codes of number of control subjects group, numbers of control subjects in group and type of control command "enable" or "disable". Blocks for signaling and controlling device are realized so, that state of each motor drive is shown by correlating bi-pulse code - pair of signals "10" for enabled and "01" for disabled state of motor drive. Simultaneously with encoding of state of motor drive, diagnostics of serviceability of equipment and communication chains of device with territorially distributed motor drives is performed, as a result of which correlation bi-pulse code is transformed to conditionally correlative code. Conditionally correlative bi-pulse code contains, except the two mentioned above, two additional code combinations - "11" for fixing lock between common buses "enable" and "disable" for all motors, or individual buses of different motor drives, and "00" - for fixing tears of diagnosed chains of communication between motor drive and device.

EFFECT: improved trustworthiness, expanded informational and functional capabilities of device.
