A software protection method for intelligent ied control switchgear

Abstract

The invention discloses a software protection method for an intelligent IED control switch cabinet. The intelligent IED control switch cabinet comprises an MCU, a human-machine interface, a control execution unit, a display unit, a communication unit and a switching circuit which are integrated on a shell of the same device, wherein an acquisition unit is connected to the MCU through the switching circuit capable of converting an acquisition signal to be recognized by the MCU; the MCU is also respectively electrically connected to the human-machine interface and the communication unit; and the human-machine interface is respectively electrically connected to the control execution unit and the display unit. The method has a prefect comprehensive protection function, meets operation requirements of different projects, integrates switch cabinet state on-line monitoring, control, protection and communication and avoids the problems of repeated signal acquisition, complicated wiring and the like.

Description

technical field [0001] The invention relates to an intelligent electronic device (IED), in particular to a software protection method for an intelligent IED to control a switch cabinet. Background technique [0002] The instrument room of the existing switchgear generally has integrated protection device + digital display instrument + intelligent control device + wireless temperature measurement device + temperature and humidity controller + three-phase live display + electric chassis vehicle control module + electric floor knife control module, the above equipment Independent and large in number, the results are: 1. The instrument room of the switchgear is large, making it impossible to miniaturize the switchgear; 2. There are many secondary cables, the wiring workload is large, and there are many fault points; 3. The hardware configuration is repeated, Each device needs to be equipped with a power module, communication module, CPU, housing, and display screen, resulting in...

The instrument room of the switchgear is large, making it impossible to miniaturize the switchgear; 2. There are many secondary cables, the wiring workload is large, and there are many fault points; 3. The hardware configuration is repeated, Each device needs to be equipped with a power module, communication module, CPU, housing, and display screen, resulting in waste of hardware costs; 4. Repeated collection and processing of signals, switching signals, and remote measurement lights; 5. Diversified communication interfaces, communication between manufacturers The protocol is not fully compatible; 6. The interoperability of equipment is poor, and the operation methods and interfaces of equipment from different manufacturers are inconsistent, which brings inconvenience to on-site maintenance
