Abstract

The invention discloses a control system for a subway safety door, comprising: a master monitor system, a central control panel interface unit, an input service unit, a control center server and a plurality of door unit controllers, wherein the master monitor system is connected with the central control panel interface unit through a PROFIBUS bus; the master monitor system is connected with the input service unit and the control center server through a MODIBUS bus; the input service unit is connected with the central control panel interface unit through the PROFIBUS bus; the central control panel interface unit is connected with the plurality of door unit controllers through the PROFIBUS bus; and when the master monitor system have faults and cannot work normally, the input service unit is communicated with the control center server through the MODIBUS bus, so as to transmit state information of the safety door to the control center server. The system provided by the invention can improve the safety of the subway.

Description

technical field [0001] The invention relates to a subway safety door system, more specifically, to a subway safety door control system. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of a network of a subway safety door control system in the prior art. In the subway safety door system, it is generally connected with the MMS (Master Monitor System) through the PROFIBUS bus for communication, and then through the MODIBUS The bus transfers information to an Operation Coordination Center (OCC, Operation Cooperation Center), where the OCC may also be called a control center server. [0003] PROFIBUS is an international, open fieldbus standard that does not depend on equipment manufacturers. PROFIBUS transmission speed can be selected within the range of 9.6kbaud ~ 12Mbaud and when the bus system starts, all devices connected to the bus should be set to the same speed. Widely applicable to manufacturing automation. Process industry automatio...
