Description

Background
The ubiquitous power internet of things is an intelligent service system which fully applies modern information technologies such as mobile interconnection, artificial intelligence and the like and advanced communication technologies around each link of a power system, realizes the mutual object interconnection and man-machine interaction of each link of the power system, and has the characteristics of comprehensive state sensing, efficient information processing and convenient and flexible application. The application of the power industry to the Internet of things mainly lies in the fields of new energy power generation monitoring and prediction, intelligent electric meter measurement, micro-grid system monitoring and the like. Meanwhile, the technology of the internet of things provides technical support for improving the efficiency and the power supply reliability of a power grid, and the RFID technology, various sensors, positioning technology, image acquisition technology and the like enable services such as warehouse management, transformer substation monitoring, emergency repair positioning and scheduling, routing inspection positioning, fault identification and the like to be flexibly, efficiently and reliably intelligently applied.
The current power system is limited to the collection of a small amount of data and lacks data analysis and processing capacity. The power supply service guarantee system and the power supply service guarantee method are usually managed through a plurality of sets of power supply service platforms, and required data needs to be manually inquired by various different systems according to requirements. Data among all sets of systems are not shared, so unified management and control cannot be realized, and the updating and upgrading difficulty of the systems is high. Due to the lack of information such as equipment parameters fed back in real time, a high-efficiency communication mode and data analysis and processing capabilities, faults are difficult to find in real time, the finding is slow, and the response time of power supply services such as emergency repair is long. The root cause of the problem that multiple sets of power systems cannot be shared is that different power systems use different communication protocols for data transmission, or that the protocols used by devices in the power systems are different. For example, the system a uses LORAWAN protocol to transmit data, the system B uses NB-IoT protocol to transmit data, and the system C uses self-developed protocol to transmit data, and the A, B, C three systems cannot integrate data due to different communication protocols.

However, many power devices having data transmission with external devices also adopt different system customization specifications according to different manufacturers, and data cannot be directly transmitted and received by using a uniform interface.
The embodiment provides a transformer substation intelligent support platform system based on the ubiquitous internet of things, the main part of the transformer substation intelligent support platform system is a cloud server, the cloud server is connected with an external power system and receives and stores data information, and meanwhile, the cloud server sends an instruction to the power system to control the power system. The external power system includes device or system software having a data transmission function used in the power system.
Then, the whole cloud server is provided with a back-end data interface, and the input data adopting the special protocol is converted into the general protocol for storage through a back-end protocol conversion module group for converting the special protocol arranged on the back-end data interface.
The back end data interface comprises a general protocol interface and a special protocol interface, and the back end protocol conversion module is linked with the special protocol interface. The cloud server is also provided with a front-end data interface and a front-end display port, the cloud server shares data with an external system through the front-end data interface and displays an interface to terminal equipment through the front-end display port; the interface is a Web UI, and the Web UI calls data stored in the cloud server through a front-end data interface.
The platform provided in the embodiment adopts a uniform interface to collect data aiming at different communication protocols, so that a system architecture with multiple protocol conversion modules is developed based on the ubiquitous internet of things concept, and the platform not only can receive and store data transmitted by different subsystems, platforms and equipment, but also can uniformly display collected real-time data through a front-end display interface. And the client can send a request to the platform through the front-end display interface and send an instruction to the linked external power system, the linked platform or the linked power equipment through the platform for control.
Because the platform does not change the internal data interaction mode of the existing subsystem or power equipment, the platform plays a role in data link aggregation. For each linked external subsystem and power device, a separate data interface for data transceiving is originally provided, or a common TCP/IP protocol or an http protocol is adopted, and the transmission mode also includes multiple modes, such as a common internet of things NB-IoT mode, a bluetooth mode, and the like, but any transmission mode and data communication protocol has a data transceiving function, and can be linked through an established network system for data transmission.
In order to deal with multiple protocol types adopted by different systems, in this embodiment, a backend protocol conversion module group is arranged to convert a special protocol, and the backend protocol conversion module is a combination of multiple protocol converters, and data transmitted into the platform can be converted into a general protocol for multiple different protocols in an extensible protocol conversion group manner, and is stored by the cloud server to update the data.
Compared with the existing electric power information platform, downlink equipment or systems mostly need to be updated, a unified data communication mode is adopted so as to facilitate timely uploading of information data, the system is compatible with subsystems and equipment with multiple communication protocols, the running state and detection data of electric power equipment in a certain area can be summarized, the electric power equipment can be displayed at terminal equipment in real time, and meanwhile, data sharing can be carried out on other systems through independent data interfaces.
And a rule chain for judging the incoming data and configuring is also arranged in the cloud server, and the rule chain judges the protocol type of the incoming data and then transfers the data to a corresponding back-end data interface to enter the cloud server.
The essence of the rule chain is that various firewall rules of a specific data packet are sequentially put into the corresponding chain according to the sequence. Incoming telemetry or attributes may be data validated and modified prior to being saved to a database, and the telemetry or attributes may be copied from the device to the associated asset so that the telemetry may be aggregated. For example, data in multiple devices may be aggregated into related assets. Because the back-end data interface comprises a general protocol interface and a special protocol interface, the rule chain can judge the communication protocol adopted by the incoming data and then link the corresponding address for processing.
The back end protocol conversion module comprises an uplink protocol conversion group and a downlink protocol conversion group; the uplink protocol conversion group comprises a plurality of uplink protocol converters, and the corresponding uplink protocol converters are called to analyze after the rule chain judges the special protocol type adopted by the data transmitted from the external power system.
The downlink protocol conversion group also comprises a plurality of downlink protocol converters, and the data transmitted by the cloud server is converted into the protocol type corresponding to the corresponding external power system through the corresponding protocol converter and is transmitted.
An extensible protocol converter is provided in the system, so that data of different protocol power systems can be shared. The protocol converter is divided into an uplink protocol converter and a downlink protocol converter, and data are firstly transmitted into the uplink protocol converter along with a rule chain by calling an HTTP or MQTT interface used for data access by the system. The main function of the up-converter is to parse the payload of incoming data and convert it to the format used by the system.
For example, a system has incoming 2-ary data, the first 8 bytes of which represent temperature, and the data is converted to a format that TB can use by writing code in the upstream protocol converter using javascript. Similar to a method for writing data capable of being converted in real time, different protocol converters can be added according to different protocols, and the protocol of the incoming data is judged in a rule chain, so that the data can automatically select different uplink protocol converters. So that power systems or devices using different protocols can be integrated into the system. The data downlink is similar to the above steps, and the data is converted by the downlink protocol converter, and then is transmitted after being converted into the data format of the opposite system. The addition, deletion, modification and check of the protocol converter do not need to restart the system and carry out real-time processing.
The communication protocol corresponding to the universal protocol interface in this embodiment includes HTTP, CoAP, and MQTT.
The three protocols are common internet of things application layer protocols and can also comprise XMPP and SoAP. The MQTT protocol has the advantages of supporting all platforms and having a wider application range. However, since many devices in the internet of things are resource-limited at present, only a small amount of memory space and limited computing power are available, and the conventional HTTP protocol is too bulky and unsuitable for application in the internet of things. Therefore, the CoAP is a communication protocol based on REST architecture, the transport layer is UDP, and the network layer is 6LowPAN (low power consumption wireless local area network oriented IPv 6).
MQTT is a many-to-many protocol in which multiple clients pass messages through a central broker, decoupling producers and consumers by having the clients publish messages, broker for message routing and replication.
The external power system includes a plurality of power system platforms and a plurality of power devices with data interfaces for data communication. The front-end data interface includes a REST API and a Websocket API.
The platform system is connected with an artificial intelligence platform for data analysis, and the artificial intelligence platform is in data transmission with the cloud server through a front-end data interface.
And the back-end protocol conversion module is configured through the Web UI.
The front end of the system is displayed externally through a Web UI, the terminal equipment is linked to a front end display port of the cloud server, the interface of the Web UI is displayed on display equipment on the terminal, meanwhile, the Web UI can call data of all power systems and power equipment stored in the cloud server, such as power cabinet attributes, power tool attributes, staff attributes, workflow data and various sensor attributes, on the terminal equipment, partitioning is carried out on the Web UI interface according to the contents or partitioning is carried out according to areas, so that a user can know the operating states of the power systems and the power equipment managed by the system more visually, and meanwhile, real-time monitoring and analysis are carried out on the data through an artificial intelligent platform.
The artificial intelligence platform can monitor the power equipment connected with the whole system through a preset program, and once part of state parameters in the uploaded data exceed a threshold value, real-time alarming can be carried out. The alarm modes are various, the alarm information can be directly sent to the terminal equipment through the artificial intelligence platform, the instruction is sent to the cloud server at the same time, the Web UI is warned at the same time through the cloud server, and the instruction can be directly sent to the corresponding power equipment or power system with abnormal data to act.
The artificial intelligence platform can also prejudge the running state of the whole system, a single subsystem or the power equipment according to the data stored in the cloud server, train a plurality of models by utilizing a deep learning algorithm, train different types of systems or equipment, and finally analyze the failure risk rate according to the data change trend within a certain time.
The data collected on the whole platform not only include text data, but also uploaded streaming media files (audio, image and video), such as video monitoring data of some monitoring cameras, a user can directly click a corresponding camera link on the interface of the Web UI, then the Web UI can play the real-time picture of the camera, and the user can also call the video files stored in a certain time to play.
For example, in a management system of an electric power worker, identity information corresponding to the worker is stored, the worker information bar corresponding to the area is selected, then the relevant worker can be found correspondingly, a photo of the worker is called out on a display of the terminal device, the identity information is attached, even the working duration of each day, if the worker has a work log uploaded to the system, the worker can also directly view the work log through the system (when a user uses a Web UI to link a cloud server, login operation can be performed, and the Web UI can open management authority of a corresponding level according to the authority of the login worker).
The whole platform in this embodiment is a platform layer in the whole ubiquitous power internet of things system, that is, a data stream in the sensing layer is received through the network layer, and after the data stream is collected uniformly, the data stream is linked with the display interface of the application layer, so that unified information management and feedback are performed.
At the level of an application layer, a user can access cloud server data through a mobile phone APP/WeChat public number and a web end through a WEI UI, check the real-time state of the power equipment, and check corresponding data according to different permissions of a login person. The general application layer is divided into an internal part and an external part, the internal account number can not only check real-time data, but also can send instructions through the platform to conduct regulation and control, namely, the cloud server can send RPC instructions to the equipment, and the purpose of remotely controlling the equipment is achieved.
The front end can share data with other systems through the REST API and the Websocket API, and therefore the expansion capability of the system and the data sharing capability are improved. And the rear end can judge conventional protocols (HTTP, COAP and MQTT) or special self-built protocols through a rule chain and then convert the protocols by adopting a corresponding protocol converter, so that the method is suitable for various power systems. The rule chain may perform data validation and modification of incoming telemetry or attributes before saving to the database; while the telemetry or attributes are copied from the device to the associated asset so that the telemetry may be aggregated. For example, data in multiple devices may be aggregated into related assets. The rule chain can also trigger operations based on device lifecycle events, e.g., create alerts if the device is in an online/offline state.
Because various JS components are added in advance in the system, after data is added into the system, the added components can be directly clicked on the Web UI page, and the system can be simply configured. Recoding is avoided, and the required visualization components can be dynamically expanded as required. And moreover, an online component writing function is provided, and components can be added and modified online. Due to the implementation of the function, the display of the data only needs to be configured as required, and repeated JS codes do not need to be rewritten.
In the perception layer, some power devices can transmit data in a near field communication mode, for example, a sound vibration monitoring system of a main device such as a transformer, a reactor and a GIS, and other extended sensors or controllers are connected into a platform through a bluetooth gateway and an LORA gateway. Aiming at newly developed sensors and controllers, a unified communication protocol is formulated according to the unified Internet of things access specification preferentially
The system is also provided with the self-owned MQTT gateway, thereby providing the functions of configuring and controlling the equipment which starts the MQTT protocol, registering the electric equipment to the system in batches, and configuring and controlling the electric equipment connected through the gateway in batches.
The present invention is not limited to the above-described alternative embodiments, and various other forms of products can be obtained by anyone in light of the present invention. The above detailed description should not be taken as limiting the scope of the invention, which is defined in the claims, and which the description is intended to be interpreted accordingly.
