Title: Transmission reception right allocation system in polling access transmission system
Inventor: KIMURA ETSUHIRO
IPC: H04L12/40
Filed: 1992-12-25
Abstract: PURPOSE:To dynamically allocate a transmission reception right preferentially to a terminal controller necessitating data transmission. CONSTITUTION:When a central equipment and plural terminal controllers are connected in multi-point system with a transmission line and data are sent in time division multiplex system with polling access system, a terminal controller distribution means 14 divides the plural terminal controllers into an allocated terminal controller group and a non-allocated terminal controller group and issues a transmission request cyclicly to only the allocated terminal controller group to allocate a transmission reception right and monitors the transmission state during transmission period with the allocated terminal controller group and discriminates urgency of data transmission based on the result of transmission state monitor after the end of transmission and replaces an allocated terminal equipment having no urgency with one of the non-allocated terminal controller group sequentially. Thus, the reduction in a substantial data transmission speed is avoided without decreasing the transmission reception right allocation number.

A first sawtooth wave signal VS1 generated from the detection signal of the virtual neutral point and voltages Va1 and Va2 are input to a second comparing portion 19, and two kinds of signals are output. Also a terminal voltage V and a terminal voltage W are handled as same as the above and, in consequence, output timing pulses from the second comparing portion 19, a fourth comparing portion 25 and a sixth comparing portion 31 are input to a combining portion 32, and the combining portion 32 outputs by each timing pulse the ignition timing pulses required for obtaining the position detection signal of a rotor.
