The environment monitoring system realizes the following 8 main functions: remotely turning on or off the running state of the air conditioner, switching the working modes (automatic, refrigeration, heating, dehumidification and air supply) of the air conditioner and adjusting the temperature; secondly, remotely starting or stopping the fan and repairing the hang tag; remotely starting or stopping the dehumidifier and the maintenance listing; fourthly, remotely starting or stopping the water pump and maintaining the hanging plate; monitoring threshold value alarms such as temperature, humidity, wind speed, rainfall, water level and the like, and remotely configuring threshold values and alarm mode settings; automatically controlling the start and stop of an air conditioner and a fan, adjusting the operation mode and the like according to the out-of-limit alarm threshold value of indoor temperature and humidity; seventhly, the water pump is automatically controlled to start according to the water level alarm of the water collecting well, and the alarm is automatically stopped after being recovered; and automatically controlling the heater to start and stop according to the out-of-limit temperature and humidity alarm threshold value in the terminal box.

table 1 main input and output information list of auxiliary control subsystem of transformer substation
Fire-fighting information system, safety protection operation monitoring system, environment monitoring system and SF6And the monitoring system, the lighting control system, the online monitoring system and other different subsystems divide the service attributes into areas.
Information interaction objects and data attributes in each subsystem are divided into two main categories: the method comprises the steps of subsystem internal communication and subsystem inter-subsystem communication, different types of interaction information are respectively labeled and divided according to the labels, non-public data are only interacted in respective virtual subnets, and public data are interacted in a main network.
For example, the fire alarm information system receives information of the fire alarm controller, the information comprises information of the fire alarm controller, the controller indicates a fire position, the information of the fire position is related to a plurality of detection elements in the alarm area, each detection element is provided with a preset code corresponding to the detected area, therefore, the code attribute of the detection element output to the fire alarm information system by the fire alarm controller is Integer (Integer) data, and the alarm state attribute of the detection element is Boolean (Boolean) data. The fire-fighting information system starts the automatic fire-fighting equipment and the fire-fighting linkage control equipment through the automatic fire-fighting control device according to the received alarm information, and the fire-fighting control information comprises codes (integer data) corresponding to the fire-fighting linkage control equipment and the opening and closing states (Boolean data) of the equipment. The data interaction of the fire alarm controller and the fire protection information system is only in the fire protection information system, and other subsystems are not involved, so that the input and output data only need to be in the slice area, and are marked as a 'fire protection information system'.
In another example, the SF of the circuit breaker is monitored in the online monitoring system of the transformer substation6Gas pressure density, gas micro-water content, partial discharge, breaker spring pressure, mechanical properties, etc., wherein the breaker SF6Gas pressure density, gas micro water content is SF6Part of the content monitored by the monitoring system, i.e. the on-line monitoring system and the SF6The monitoring system receives the same kind of output information of such devices. The substation online monitoring system is a monitoring system, and therefore only receives information, and does not output information. SF6The monitoring system is a monitoring and control system, and needs to realize the functions of acousto-optic alarm on the start-stop site and start-stop of the exhaust fan, so that the information is received and output.
SF6The monitoring system comprises gas temperature, pressure, density and micro water content, the above state attributes are floating point (Float) data, and the on-line monitoring system and SF6Monitoring systems the data that both systems need to receive is identified as "public information". For SF6The monitoring system outputs acousto-optic alarm of start-stop site and control information (Boolean data) of start-stop exhaust fan, only uses in the system, and is marked as' SF6A monitoring system ".
According to the requirement of service expansion, if a new system is accessed, the configuration can be carried out according to the method, so that the safety of each subsystem is ensured, and the data sharing among different systems can be considered.
And secondly, dividing the comprehensive monitoring system network of the transformer substation auxiliary system into a plurality of virtual subsystem networks according to the divided service areas, wherein each service area corresponds to one virtual subsystem network.
Furthermore, a network slicing technology is adopted to divide the comprehensive monitoring system network of the transformer substation auxiliary system into a plurality of virtual subsystem networks. Network slicing is to organize a plurality of virtual networks according to service characteristics by reconstructing topology resources, such as links, nodes, ports and internal resources.
The network slice is a networking mode according to service requirements, a plurality of virtual end-to-end networks are separated from a unified network, and each network slice is logically isolated from an access network bearing network to a core network so as to adapt to various service requirements.
The reconstruction adopts an SDN (Software Defined Network) architecture. When the bottom layer physical network resource is in failure or the network link load is overlarge, the virtual link mapped to the network physical route is mapped again.
The virtual network reconstruction comprises 3 steps: selecting a virtual link needing to be migrated on a physical link; selecting a virtual link needing to be migrated in the target physical link; and thirdly, selecting adjacent links, migrating the virtual link to be migrated to the target physical link, and reallocating network resources.
And (4) performing logic slicing in a physical network of the transformer substation based on the areas divided by the subsystems in the step one, dividing the areas into a plurality of virtual subnets, wherein the broadcast messages of the subnets can only be broadcast in the subnet and cannot be transmitted to other subnets. The devices in the virtual sub-networks can directly communicate with each other, and the communication between the devices in different sub-networks needs to be forwarded through the route, so that all data are not transmitted through route broadcasting like the prior art.
Furthermore, each virtual subsystem network realizes logic isolation on a forwarding level, a control level and a management level, and meets the requirements of various types of service services.
The control layer is the layer where various communication protocols work, and by controlling and managing the operation of various network protocols, the switch and the router can sense the equipment, the link and the operating protocol of the whole network and adjust in time when the network changes.
The forwarding layer is the sending of service messages, and the data layer sends data according to the address information of the control layer, depending on the analysis, forwarding and the like of the messages by the network equipment.
The management layer is used for monitoring the operation condition of the system so as to ensure the safe and stable operation of the system, and can timely isolate faults when unit faults occur so as to ensure the normal operation of other parts in the system.
Furthermore, data communication of different virtual subsystem networks are isolated from each other, services on each virtual subsystem network are isolated from each other, and data communication and services of other virtual subsystem networks cannot be influenced when one virtual subsystem network fails.
The network logic isolation isolates the communication of different networks by virtual logic equipment and non-physical equipment, and adopts mechanisms such as a security protocol, access control, identity authentication, encryption signature and the like to control access, thereby ensuring the safe interaction and sharing of data information and realizing the isolation and data exchange in the internal network.
The network logic isolation method is characterized in that a virtual subsystem network interacts with interfaces with the same virtual Label in a network broadcast domain, the Label is identified to forward a message to a designated port, all ports on one switch are in the same broadcast domain, the switch can reserve a predefined port in each broadcast domain in a virtual Label mode, and an isolation network of a plurality of subsystems is established through Multi-Protocol Label Switching (MPLS).
Furthermore, each virtual subsystem network can share service information to upper layer services, and the difference between slices and physics is shielded.
The upper-layer service means that the monitoring host of the station end of the auxiliary equipment acquires physical area data of the transformer substation, such as security protection, power environment, light air-conditioning control and the likeAnd information such as online monitoring data and the like is acquired through the fire-fighting information transmission control unit, and data processing and analysis are completed. The system is deployed on an auxiliary equipment station side monitoring host of a transformer substation, and shows fire protection, safety precaution, environment monitoring and SF of the transformer substation in a client side mode6Monitoring, lighting control, transformer substation on-line monitoring and the like, and comprehensive monitoring of auxiliary equipment of the transformer substation is realized.
The communication protocol between the virtual subsystem network and the upper-layer service adopts a DL/T860 transformer substation communication network and system, and the universal standard in the field of power system automation.
The SDN architecture is adopted, the difference of bottom layer physical forwarding equipment in each subsystem is shielded through an interface of network management equipment, the virtualization of resources is realized, and an upper layer service application interface is connected with a transformer substation auxiliary system to comprehensively monitor system services, perform network configuration and call network resources as required. And calling the network capability of the SDN opened to the outside by utilizing the SDN northbound interface. When a service networking requirement occurs, the corresponding network can be configured in a centralized manner on the management platform and is automatically issued to the network equipment of the subsystem by the SDN in a unified manner.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
