The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 1, fig. 1 is a 61850 standard-based data conversion method provided by an embodiment of the present invention, and is applied to a substation gateway, where the substation gateway is communicatively connected to a collection device and a server platform, respectively, and the method includes, but is not limited to, step S110, step S120, and step S130.
Step S110, acquiring initial data uploaded by an acquisition device;
step S120, acquiring a mapping relation of a data set forwarding information model corresponding to the acquisition device from a preset configuration file;
and S130, generating target logic node data according to the mapping relation of the data set forwarding information model and the initial data, and sending the target logic node data to the server platform, wherein the target logic node data meet the 61850 standard.
It should be noted that the 61850 standard described in this embodiment is an IEC61850 standard, and is not described in detail later.
It should be noted that the substation gateway in this embodiment may be a programmable substation gateway capable of supporting the 61850 standard, and of course, any number of ports may be provided to connect different acquisition devices. It can be understood that when the substation gateway is connected to a plurality of acquisition devices, the generation of target logical node data may be performed on the data reported by each acquisition device one by one, or the target logical node data may be uniformly executed after all the data are acquired, which is determined specifically according to the type of the acquisition device, and is not limited herein.
It can be understood that the acquisition device can be a parameter acquisition device of common power equipment, and also can be an environmental sensor arranged in a transformer substation or a machine room, such as a temperature and humidity sensor, and the specific type of the acquisition device is selected according to actual requirements, and acquired data can be transmitted to a transformer substation gateway through a wireless network or serial port communication.
It should be noted that the initial data uploaded by the acquisition device may be data generated according to a private protocol thereof, and only the target logical node data conforming to the 61850 standard may be generated by combining the mapping relationship of the data set forwarding information model. It can be understood that the target logical node data are unified into the data meeting the 61850 standard, the process of analyzing the received data by the server platform can be omitted, and the target logical node data are strictly packaged according to the 61850 standard, so that the target logical node data can be directly used for various rear-end platforms of the server platform, and the efficiency of data acquisition is improved.
It can be understood that the configuration file may be configured in the substation gateway in a local configuration manner, or may be configured in a remote issuing manner, and a specific generation manner may be selected according to actual requirements. It can be understood that the configuration file may include operation parameters of the substation gateway, and may also include a mapping relationship between various proprietary protocols and a data set forwarding information model of the 61850 standard, so that by adding a mapping relationship between the data set forwarding information model in the configuration file, it is possible to implement that all the substation gateways support the newly added proprietary protocol, thereby effectively simplifying the configuration of the substation gateway, and enabling the substation gateway to be plug-and-play.
It can be understood that the mapping relationship of the data set forwarding information model may include an expression manner of each parameter in different protocols, for example, the mapping relationship may be implemented in an xml comparison table, or may also be implemented in a functional mapping relationship, so that the parameter in the initial data may be converted into target logical node data conforming to the 61850 standard, and the specific conversion method is not limited in this embodiment.
In addition, referring to fig. 2, in an embodiment, the step S120 in the embodiment shown in fig. 1 further includes, but is not limited to, the following steps:
step S210, acquiring equipment information of the acquisition device from the initial data;
step S220, determining the mapping relation of the data set forwarding information model according to the equipment information, wherein the mapping relation of the data set forwarding information model is the mapping relation of data of a private protocol corresponding to the equipment information and data of the 61850 standard.
It should be noted that the device information may be information characterizing the type of the acquisition apparatus device, such as a specific model, or an adopted proprietary protocol, and may be used to determine a mapping relationship of a specific data set forwarding information model.
It is understood that the proprietary protocol may be any data protocol used by the acquisition device, and it is sufficient to determine that the initial data sent by the acquisition device is generated according to a certain protocol.
It should be noted that, in order to improve the application range of the substation gateway, before use, after determining the private protocol of the acquisition device, the mapping relationship between the private protocol and the 61850 standard may be determined in advance, and the configuration of the substation gateway is completed in advance in a configuration file manner, so that the substation gateway can automatically convert the initial data of the private protocol into the target logical node data of the 61850 standard.
In addition, referring to fig. 3, in an embodiment, the step S130 in the embodiment shown in fig. 1 further includes, but is not limited to, the following steps:
step S310, determining a data standard of the target logic node data according to the 61850 standard;
and S320, acquiring corresponding target logical node data which accords with the 61850 standard from the initial data according to the mapping relation of the data set forwarding information model.
It should be noted that, because the 61850 standard has strict data type requirements, when generating target logical node data, it is necessary to ensure that the generated parameters meet the requirements of the 61850 standard, and based on this, the mapping relationship of the data set forwarding information model may include the parameter type of each data standard in the private protocol corresponding to the collection device, thereby implementing the mapping of data.
It can be understood that after the acquisition parameters are obtained, data summarization can be performed according to a format conforming to the 61850 standard, so as to ensure that the target logical node data can conform to the 61850 standard.
In addition, referring to fig. 4, in an embodiment, the step S320 in the embodiment shown in fig. 3 further includes, but is not limited to, the following steps:
step S410, when it is determined that the initial data at least comprises the acquisition parameters corresponding to the parameter types of the target logic node data, the target logic node data is obtained from the initial data according to the mapping relation of the data set forwarding information model.
It should be noted that, because the data acquired by the acquisition device in different periods may be different, after the initial data is acquired, it may be determined whether the parameter types in the initial data conform to all the parameter types specified in the 61850 standard, and if so, the target logical node data may be generated according to the initial data; otherwise, if the parameter type in the initial data is less than the parameter type specified by the 61850 standard, the generated target logical node data may lack parameters, so that the target logical node data does not conform to the 61850 standard, resulting in failure in reporting the server platform. It is understood that for initial data whose parameter type does not satisfy the parameter type specified by the 61850 standard, a discarding operation may be performed to reduce the amount of storage of the data.
In addition, referring to fig. 5, in an embodiment, before performing step S210 in the embodiment shown in fig. 2, the following steps are further included, but not limited to:
step S510, when the configuration file does not include the mapping relationship of the data set forwarding information model corresponding to the device information, generating error reporting information and sending the error reporting information to the server platform.
It can be understood that when the configuration file does not include the mapping relationship of the corresponding data set forwarding information model, the substation gateway needs to be reconfigured, and therefore, a manager can be prompted to update the configuration file by generating error reporting information.
It should be noted that step S510 may be performed once each time the initial data is acquired, so as to ensure the reliability of data conversion, and certainly, since the private protocol of the acquisition device does not change frequently, the detection may also be performed when the initial data is acquired for the first time. It can be understood that, in the case that the configuration file is detected to lack the mapping relationship of the data set forwarding information model, the detection may be performed in a loop until the mapping relationship position of the corresponding data set forwarding information model is detected.
It can be understood that, since the substation gateway can upgrade the configuration file in the using process, and the private protocol of the acquisition device can also be upgraded, it can be determined whether the configuration file is modified after the initial data is acquired each time, and if the configuration file is modified, the mapping relation of the latest data set forwarding information model can be acquired for subsequent operations.
In addition, in an embodiment, the device information includes at least one of:
an IP address;
the device model;
the serial number of the interface connected with the substation gateway.
It can be understood that, because the collection device does not change frequently after being installed, and each change needs to be updated at the configuration end, the IP address of the collection device is knowable to the substation gateway, that is, the substation gateway can determine a specific corresponding collection device through the IP address, and based on this, specific device information can be determined through the IP address, so as to determine the mapping relationship of the corresponding data set forwarding information model. Similarly, the initial data may carry data representing the device model, and the mapping relationship of the corresponding data set forwarding information model may be determined by using the uniqueness of the device model. Similarly, for facilities such as a substation, interfaces of a substation gateway are generally strictly regulated, and therefore, a specific corresponding acquisition device can be determined through the serial number of the substation gateway interface, so that the mapping relation of the data set forwarding information model is quickly matched.
In addition, referring to fig. 6, in an embodiment, the step S130 in the embodiment shown in fig. 1 further includes, but is not limited to, the following steps:
step S610, acquiring a fault threshold corresponding to target logic node data;
step S620, when the target logical node data is greater than the failure threshold, determining that the target logical node data is failure data, and sending the determined failure data to the server platform.
It should be noted that the fault threshold may be pre-configured in the substation gateway, or may be adjusted in real time according to the feedback of the server platform, and may be determined according to actual requirements. It can be understood that the collected target logic node data may include a plurality of data types, such as common power parameters, environmental temperature and humidity parameters, and a corresponding fault threshold may be set for each type of target logic node data according to actual requirements, so as to ensure that an abnormal condition of the parameters can be quickly discovered.
It should be noted that when the target logical node data is determined to be the failure data, the target logical node data may be added with a corresponding tag and kept reporting, so that the server platform can determine that the data is the failure data.
In addition, referring to fig. 7, in an embodiment, the step S110 in the embodiment shown in fig. 1 further includes, but is not limited to, the following steps:
step S710, determining a sampling period, and acquiring initial data uploaded by the acquisition device according to the sampling period.
It should be noted that, for the acquisition device, various parameters acquired by the acquisition device are real-time data, and therefore, a certain sampling period, for example, a certain time period, can be set in the configuration file, and after the time period is reached, the substation gateway acquires data of the current acquisition device as initial data, generates corresponding target logical node data, and reports the data. Of course, the initial data acquisition can be realized through a polling mode, and a specific mode can be selected according to actual requirements.
In addition, referring to fig. 8, an embodiment of the present invention further provides a substation gateway, where the substation gateway 800 includes: a storage module 810, a processing module 820, and a computer program stored on the storage module 810 and executable on the processing module 820.
The processing module 820 and the storage module 810 may be connected by a bus or other means.
The non-transitory software programs and instructions required to implement the 61850 standard based data conversion method of the above embodiment are stored in the storage module 810, and when executed by the processing module 820, the 61850 standard based data conversion method applied to the substation gateway 800 in the above embodiment is executed, for example, the method steps S110 to S130 in fig. 1, S210 to S220 in fig. 2, S310 to S320 in fig. 3, S410 in fig. 4, S510 in fig. 5, S610 to S620 in fig. 6, and S710 in fig. 7 described above are executed.
