Embodiment 1

[0037] The underground station control system adopts this control system and adopts a hierarchical distributed structure. The equipment mainly includes the programmable logic control modules installed in the control cabinets at both ends of the station A and B, and the control cabinets installed in the environmental control electric control room. The photoelectric converters and network converters in the cabinet and the remote communication sub-stations installed on different equipment floors of the station. The programmable controller adopts redundant S7-400H series products, and a set of redundant CPU 414-4H communication controllers are installed in the environmental control electric control rooms at both ends of the station. The remote communication substation adopts ET200M, the remote station is installed in the module box, and the module box is installed in different equipment layers of the station, and connected to the redundant controller through redundant PROFIBUS dual...

Abstract

The invention discloses a control system. The control system compiles corresponding subroutine modules according to the control characteristics of each device, and then calls the corresponding subroutines according to the control requirements of the KEMCS control system, so as to control each device, and then assists to meet The auxiliary program blocks compiled according to the requirements of redundant settings can achieve perfect control. The control system is mainly composed of PLC communication protocol software, HMI monitoring software, HMI monitoring configuration software, network communication software, simulation test software, and database storage designed into modules. The software is composed of intermediary software bus connection through the CORBA public object request agent architecture and follows the TCP / IP protocol to realize communication, so that module failures are separated; the invention controls the environmental control of rail transit stations and intervals and the safety of other electromechanical equipment , Efficient and coordinated operation, to ensure a good and comfortable environment in subway stations and intervals.

Description

technical field [0001] The invention relates to a control system, which is applied to industries such as rail transit, iron and steel, chemical industry, electric power, environmental protection, water treatment, metallurgy, and coal. Background technique [0002] The environment and equipment monitoring major (BAS major for short) in rail transit engineering is a very important part. It is a layer between the terminal equipment layer and the ISCS station control layer. It is responsible for the collection of the entire BAS professional equipment data, Command issuing and forwarding work. [0003] The BAS major needs to establish a redundant communication interface to connect with the integrated monitoring system. The main tasks are: to collect equipment information in stations and tunnels and upload them to stations or control center (OCC) workstations, and to execute action commands issued by station workstations or OCC workstations Or instruction sequence, to realize the...
