Similarly, the phrase "if it is determined" or "if a [ described condition or event ] is detected" may be interpreted contextually to mean "upon determining" or "in response to determining" or "upon detecting [ described condition or event ]" or "in response to detecting [ described condition or event ]".
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
As shown in fig. 1, which is a schematic view of an implementation flow of a data acquisition method provided in an embodiment of the present invention, the method may include:
step S10: raw data is collected.
The acquisition part consists of an adapter and a collector. Wherein the adapter collects raw data in the SCADA system through web services (web services, which are network-based, distributed modular components that perform specific tasks, adhering to specific technical specifications) using C # (a programming language).
The SCADA System (Data Acquisition And monitoring Control System) is a computer-based DCS (Distributed Control System) And an electric power automatic monitoring System; the method has wide application field, and can be applied to a plurality of fields such as data acquisition and monitoring control, process control and the like in the fields of electric power, metallurgy, petroleum, chemical industry, gas, railways and the like.
In the power system, the SCADA system is most widely applied, and the technical development is the most mature. The remote monitoring system is important in a telemechanical system, can monitor and control on-site operating equipment to realize various functions such as data acquisition, equipment control, measurement, parameter adjustment, various signal alarms and the like, namely a known 'four remote' function RTU (remote terminal unit) and an FTU (feeder terminal unit) are important components of the remote monitoring system.
And after the adapter collects the SCADA original data, transmitting the original data to the collector. The collector is a data collection tool with practical significance, and works such as local data checking of clients and local data importing are achieved.
Step S20: and processing the original data through a data bus to obtain standard data.
The data bus is used for the normalized exchange of data with each component. The data bus (english RabbitMQ) is the message middleware that supports persistent message queues. The upper level business logic is applied to the upper and lower level business logic, the upper level business logic is equivalent to the producer issuing the message, and the lower level business logic is equivalent to the consumer receiving the message and consuming the message.
The conversion into standard data is helpful to eliminate the influence caused by different format standards among different components, thereby enabling the whole system to be more uniform.
Step S30: and uploading the standard data to a cloud access layer by using the data bus.
The cloud access layer (i.e., MQTT gateway), MQTT (Message queue telemetry transport Protocol), is a lightweight Protocol based on publish/subscribe (publish/subscribe) mode, and is constructed on TCP/IP (english name Transmission control Protocol/Internet Protocol, Transmission control Protocol/Internet Protocol) Protocol. As an instant messaging protocol with low cost and low bandwidth occupation, the method has wide application in the aspects of Internet of things, small-sized equipment, mobile application and the like.
MQTT is a client-server based message publish/subscribe transport protocol. The MQTT protocol is lightweight, simple, open, and easy to implement, which makes it very versatile. In many cases, including in restricted environments, such as: machine to machine (M2M) communication and internet of things (IoT). It has found widespread use in communication sensors via satellite links, occasionally dial-up medical devices, smart homes, and some miniaturized devices.
In this embodiment, the data standard is uploaded through the data bus, and MQTT is adopted, which is the encrypted MQTT.
As shown in fig. 2, an embodiment of the present invention provides a data acquisition method, where step S10 includes:
step S11: the raw data is adapted.
In step S11, the raw data of the SCADA is arranged in a designated target device to generate a final downloadable file. This step is accomplished by the above described adapter, which serves the main purpose of: 1. and packaging the interface. 2. A real-time data query interface. 3. And subscribing and pushing real-time digital quantity. 4. A historical data query interface. 5. And an alarm data query interface.
Step S12: and acquiring the adapted original data to the data bus.
The adapter transmits data to the collector through HTTP. The raw data is transmitted to the data bus through the AMQP by the collector. The collector is used as follows; 1. real-time analog quantity is collected according to frequency. 2. And receiving real-time digital quantity change data. 3. Every hour period, full digital data (historian) is collected. 4. The breakpoint data is automatically complemented (historian). 5. Manual recruitment data collection (historian). 6. And (5) acquiring alarm data.
The HTTP is a simple request-response Protocol, and it usually runs on top of TCP (Transmission Control Protocol). It specifies what messages the client may send to the server and what responses to get.
The AMQP (Advanced Message Queuing Protocol) is an application layer standard Advanced Message Queuing Protocol that provides a unified Message service, is an open standard of the application layer Protocol, and is designed for a Message-oriented middleware. The client and the message middleware based on the protocol can transfer messages and are not limited by conditions of different products, different development languages and the like of the client/middleware.
As shown in fig. 3, it is the embodiment of the present invention that provides a data acquisition method, wherein step S20 includes:
step S21: and transmitting the original data to a converter through the data bus so that the converter converts the original data to obtain the standard data.
Wherein a converter refers to a device that converts one signal into another signal. The signal is in the form or carrier of the information present. In automated instrumentation and control systems, it is common to convert one signal into another compared to a standard or reference quantity in order to couple the two types of instruments, and therefore the converter is often an intermediate link between the two instruments (or devices).
Step S22: and transmitting the standard data obtained by the converter back to the data bus.
The function of the step is to convert the standard data required by the original data and to transmit the standard data back to the data bus. So that the data bus transmits the standard data to other module devices.
As shown in fig. 4, it is the embodiment of the present invention that provides a data acquisition method, wherein step S30 includes:
step S31: and transmitting the standard data to a repeater which is linked with the cloud access layer through the data bus.
The repeater bridges two module devices and performs data transmission on the standard data from the data bus to the cloud access layer.
Step S32: and transmitting the standard data to the cloud access layer through the repeater.
And when the standard data reaches the cloud access layer, the data acquisition work of the cloud is completed.
As shown in fig. 5, an embodiment of the present invention provides a data acquisition method, further including:
step S40: and when a corresponding transmission instruction is received, transmitting the standard data of the cloud access layer to a receiver according to the transmission instruction.
When the client network is interrupted, an instruction is given, as shown in step S40. And transmitting the standard data to the receiver through a cloud access layer.
Step S50: transmitting, by the receiver, the standard data to the data bus.
After the standard data reaches the data bus through the receiver, the standard data is transmitted to a required device module according to requirements.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
