Method for realizing automatic adjustment of BAS professional equipment of integrated monitoring system

Abstract

The invention discloses a method for realizing the automatic adjustment of the BAS professional equipment of the integrated monitoring system, and the automatic monitoring and control of the BAS professional equipment is realized by the integrated monitoring system, and the PLC of the traditional BAS system only plays the role of uploading the collected information and directly controlling the adjustment. The LUA script is used to realize the automatic control operation of the enthalpy value, and of the fan frequency conversion speed adjustment; the enthalpy value calculation and the operationalgorithm library of the frequency conversion speed are provided in the form of C++ dynamic library, and is called with the LUA script in the form of C function; The configuration definition tool ofthe comprehensive monitoring system has to be used to define the input parameters and LUA scripts of different automatic adjustment calculations; then, the operation cycle control with the backgroundbeing integrately monitored for an automatic control service is designed for the delivery of the adjustment control commands after the calculation is implemented.

Description

technical field [0001] The invention relates to the field of rail transit comprehensive monitoring systems and is applied to the control of BAS systems. Background technique [0002] In recent years, the subway integrated monitoring system (hereinafter referred to as ISCS) has developed rapidly. The integrated monitoring system deeply integrates PSCADA, BAS and other subsystems, and interconnects with other professional subsystems to realize information sharing and professional integration. Monitor each subsystem on the platform. [0003] In order to ensure a suitable temperature, humidity and ventilation environment for the subway station hall and platform floor, at present, the adjustment and control of the electromechanical equipment related to wind and hydropower in the subway station is mainly realized by the BAS system. The traditional BAS system relies on PLC for manual control of wind and water motors and electrical equipment, as well as schedule control, automatic ...

AI Technical Summary

Problems solved by technology

[0004] PLC has the fast sequential control capability of scanning according to time slices, so this monitoring method is more suitable for small-lag and small-inertia systems that require fast response, such as the control of assembly lines and boilers, while subway stations are large-lag and large-inertia systems. The subway station has a large space, the system is not airtight, and there are many links with the outside world, such as trains entering and exiting the station, people flow, vents, entrances and exits, etc. (information comes from signal, fare collection and other systems, which cannot be obtained by PLC), human body's environmental indicators (temperature , humidity, oxygen content, etc.) are not sensitive to other factors, so it is not suitable to use PLC to realize the automatic adjustment control of subway stations
