Electrolysis cell multiplex bus communications control system

摘要

PURPOSE: To control a bus transmission and reception by a cell unit fairly and without delay in a cell multiple bus communication control system. ;CONSTITUTION: Each LIF(Line interface circuit) 100 multiplexes a cell transmission right request from a self line to a line 202 by a preliminarily fixed timing from a number of cell request part 40 to a central processing part 200 and outputs the request The central processing part 200 receiving this cell transmission right request arbitrates a transmission permission from the number of cell and a priority in a number of cell request detection part 50 and the transmission permission is multiplexed from a permission data transmission part 60 to a line 201 and transmits the permission. When each LIF 100 detects the transmission permission to self circuit in a permission/timing detection part 30, it performs a transmission instruction to a bus 101 of the cell for a cell transmission part 20.;COPYRIGHT: (C)1993,JPO&Japio
