(63) after the completion of whole tasks, dedicated mobile phone application APP is pushed from the personnel that assign a task of trend control centre to be made Industry completes result.
In practical application, refering to Figure 1, which show overall system architectures of the invention.Of the invention The polynary delivery system of relay protection O&M information is made of the substation and main website two parts of dispatching terminal for being deployed in transformer substation end. Substation is responsible for the real-time acquisition of relay protection device information and is above sent, main website is responsible to analyze each substation data received, Processing and polynary publication.
Meanwhile it realizing method of the invention specific step is as follows:
1, great Qu (the safe area II) data acquisition and procession is produced
(1) data acquire: the substation by being located at the safe area II of transformer substation end is responsible for being communicated with relay protection device, complete Relay protection device is total according to acquisition in pairs.Substation acquisition data are divided into bursty data and calling two class of data.Bursty data Class data are informed in the main abnormality alarming including relay protection device, trip operation and displacement, and calling data mainly include relay Protect the data such as operating parameter, pressing plate state, sampled value and the recorded wave file of equipment;
(2) sub- main website data interaction: main station side be located at the safe area II protection and recording on-line analysis server be responsible for The substation of transformer substation end is communicated, on the one hand receive substation it is automatic on the bursty data that send, on the other hand also support to pass through master Stand end work station transmitting order to lower levels mode on duty actively from substation obtain specified data;
(3) main website Data Analysis Services: main website is filtered and intellectual analysis processing, most end form the Various types of data received At the four class results such as abnormal unit exception, secondary circuit, scene maloperation, electric network fault can be characterized, pushed away for subsequent post Inquiry is sent and browses to lay the foundation.
2, the safe area II (production great Qu) arrives the area III (office administration area) data one-way synchronization
It is most important to produce great Qu safety, strictly to forbid nonproductive area user to access production great Qu, in production great Qu Increase one-way isolation equipment with office administration section, i.e. data only allow unidirectionally to issue from the safe area II to the safe area III, no Allow any inverted access.The data of one-way synchronization cover each class model of system, figure, real time information and analysis and processing result Etc. total evidence.When system ensures that the safe any data in the area II change or increase, all it will change or increase information and compile Code, character stream information is decoded, then after the safe area III receives by real-time synchronization to the safe area III in a manner of character stream It is saved in the area III database again.
3, office administration area (the safe area III) WEB is issued
Office administration area belongs to work of electric power system Intranet, does not support access internet.For the convenience of the user in individual office The details of relay protection device O&M information can be quickly understood on computer, this system deploys Intranet in the safe area III WEB server, and WEB service end is disposed on the server, all working, administrative staff are according to respective permission, post, directly By the browser of personal work computer can look-up system information, more original must arriving specify work station on duty to consult letter Breath mode substantially increases convenience.
The content of WEB publication includes that the whole network operation summarizes, monitoring in real time, unit exception early warning, electric network fault, analyzes statistics Several major class such as report, O&M job management.
4, the safe area III (office administration area) arrives mobile access-in management area data encryption synchronization
To will be seen that system information whenever and wherever possible convenient for operation maintenance personnel, it is necessary to which Intranet information is published to outer net.This is System adds the dedicated two generations information network isolating device of an electric power in the safe area III and mobile access-in management section, and realizing will Outer net publisher server of the area the III intranet data storehouse virtual map to mobile access-in management area.
In security strategy, it is contemplated that Information Security and confidentiality, the data information being mapped in external network server pass through Following processing:
(1) map information supports customization.Usually mapping crucial analysis result data and O&M job information, as equipment is different Often, live maloperation and electric network fault summary etc..
(2) analysis result data in all external network servers is pushed to the mobile terminal of related personnel through wechat, short message Afterwards, it is automatically deleted from external network server after 24 hours.
5, mobile access-in management area and the security protection of internet access area
The outer net publisher server in mobile access-in management area accesses Internet public network, outer net publisher server through firewall In two levels of application software and hardware, access personnel white list is set, access is forbidden for user without permission.
6, internet information is issued
(1) mobile terminal wechat, the push of short message postization
It is at the first time that failure is general by systematic difference software when grid collapses or field device occur abnormal It includes, abnormal results are pushed to the mobile phone terminal of skilled addressee in a manner of wechat or short message (configurable).Information push is supported It is customized by personnel specialty post, irrelevant personnel not pushes.Postization customization requires as shown in Figure 2;
When there is new O&M job task in control centre, it can directly pass through O&M job task list single under system, O&M Personnel can receive at the first time new task job ticket sending out notice, i.e., convenient and efficient, while also achieve paperless office.
(2) public network WEB is issued
After each professional receives sending out notice, public network WEB can be logged in by accessing any computer security of internet System consults associated detailed information.The information content includes: the unit exception occurred in 24 hours, circuit exception, scene accidentally behaviour Make result and electric network fault report information, operation of power networks summary, statistical forms, dispatching down distributing live O&M job ticket And device history O&M record etc..
(3) mobile terminal APP is accessed
