Abstract

The invention discloses a multi-access interconnection device based on the standard RS-232 interface and the control method thereof. The multi-access interconnection device comprises an RS-232 sending/receiving bus and a bus driver as well as a bus connector used to be connected with computer controlled equipment and instrument equipment; the computer controlled equipment and the instrument equipment are connected with the RS-232 sending/receiving bus through the bus connector. The control method is that: a control instruction is sent to the RS-232 sending/receiving bus through the computer controlled equipment in a mode of sending a broadcast message, and the related instrument equipment automatically receives the control instruction, executes a task related to the control instrument, and then returns the execution result to the computer controlled equipment. The invention solves the problem that various different kinds of instrument equipment products of different manufacturers adopt the connection of the standard RS-232 interface with the computers to meet the requirements of modern automatic surveillance/monitoring stations being more and more huge and complicated.
