It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises an element.
The following describes in detail the technical solution proposed in the embodiments of the present application through the accompanying drawings.
The embodiment of the application also provides a protocol conversion method for the power communication protocol, as shown in fig. 1, and the method mainly comprises the following steps:
step 110, creating an execution process based on the TCP protocol and the 104 communication protocol to receive the connection request uploaded by the device.
It should be noted that the TCP protocol is a connection-oriented, reliable, byte stream based transport layer communication protocol, defined by IETF RFC 793. The 104 communication specification is about the IEC104 specification. The execution process is used for calling a preset function to analyze the 104 protocol message which is uploaded by the equipment subsequently. Wherein the creation process may be implemented by existing techniques and methods, which are not overly limited by this application.
Note that, both of the protocol conversions performed in the present application are: and uploading 104 the equipment of the protocol message and issuing the preset Internet of things platform of the MQTT protocol message. The preset internet of things platform further comprises an MQTT client, wherein the MQTT client is a device for receiving preset internet of things platform data and issuing instructions (the expression form is an MQTT protocol message) to the preset internet of things platform by subscribing to the Topic of the preset internet of things platform. Before receiving a connection request uploaded by a device based on the TCP protocol, the server can also implement the start of 104 communication protocols through the MQTT client, modify or configure 104 communication protocols in the server configuration file, implement devices controlling access, number of devices, etc.,
specifically: the server acquires connection parameters corresponding to the 104 communication protocol in the server configuration file through a preset configuration file read-write interface; wherein, the connection parameters at least comprise: device port number, device connection rate, maximum number of connected devices of the system; based on the starting instruction uploaded by the MQTT client, a preset starting button of the 104 communication protocol on the dashboard interface is triggered, and the starting of the 104 communication protocol is completed.

It should be noted that, in order to facilitate the effective function call of the execution process and avoid the blocking of the execution process, the created execution process may include an execution operation process and a monitoring process; specifically, the executing operation process is used for monitoring the occurrence event so as to call the preset function corresponding to the occurrence event. When the executing operation process calls the preset function to report errors, the restarting executing operation process of the monitoring process is triggered. The preset function is any function capable of analyzing 104 protocol messages.
Step 130, extracting device data corresponding to the device based on the device address in the analysis data and a preset device data table; and converting the analysis data and the equipment data into key value pair data in a Json format, and uploading the key value pair data to a preset Internet of things platform.
It should be noted that, the preset device data table is used for interpreting the 104 protocol packet, and indicates that the system should collect the data name from the device data collected from the parsed data, for example: device address, device name, device english name, device information description, device type, and zone ID. The generating or updating process of the preset device data table may specifically be: acquiring a collected data name corresponding to a preset device data table through a preset web front-end page, and adding or updating the collected data name to the preset device data table; storing a preset device data table into a built-in database.
The key value data is forwarded to a preset internet of things platform, which can be specifically: acquiring a Topic preset by equipment on a preset internet of things platform; the key value data generated by the device is forwarded to Topic.
Based on this step, those skilled in the art will understand that the parsed Json format data is easier to understand and the data structure is clearer than the original 104 specification message. Meanwhile, the Json data is plain text, the structure is simple, the reading speed is high, and the computer system can be more convenient to further extract, store and the like. By combining the characteristics of the equipment, the information of the power equipment can be monitored more rapidly and flexibly through the computer system, and the automation level of the power distribution system is improved.
In addition, the MQTT client corresponding to the Internet of things platform can obtain key value pair data of the device through subscribing to Topic.
And 140, when receiving the MQTT protocol message issued by the preset Internet of things platform, converting the MQTT protocol message into binary data based on the preset 104 protocol specification, and issuing the binary data to equipment corresponding to the MQTT protocol message.
It should be noted that, the receiving of the MQTT protocol message issued by the preset internet of things platform may specifically be: the MQTT client subscribes to the Topic of the preset Internet of things platform, the preset Internet of things platform receives a device control instruction (the expression form of which is an MQTT protocol message) sent to the Topic by the MQTT client, then the MQTT protocol message is issued to the server through the preset Internet of things platform, and the server completes the receiving of the MQTT protocol message.
In addition, the embodiment of the application provides a protocol conversion system for a power communication protocol. As shown in fig. 2, the system provided in the embodiment of the present application mainly includes:
a creating module 210, configured to create an execution process based on the TCP protocol and the 104 communication protocol, and receive a connection request uploaded by the device;

the issuing module 240 is configured to, when receiving an MQTT protocol message issued by the preset internet of things platform 300, issue the binary data to a device corresponding to the MQTT protocol message based on binary data specified by the preset 104 protocol to convert the MQTT protocol message.
In addition, the embodiment of the application further provides a protocol conversion device for the power communication protocol, as shown in fig. 3, on which executable instructions are stored, and when the executable instructions are executed, the protocol conversion method for the power communication protocol is implemented. Specifically, the server side sends an execution instruction to the memory through the bus, and when the memory receives the execution instruction, an execution signal is sent to the processor through the bus to activate the processor.
The processor is used for receiving the connection request uploaded by the equipment based on the TCP protocol and the 104 communication protocol, and creating an execution process; when a 104 protocol message uploaded by equipment is received, calling a preset function through an execution process to obtain analysis data corresponding to the 104 protocol message; extracting equipment data corresponding to the equipment based on the equipment address in the analysis data and a preset equipment data table; converting the analysis data and the equipment data into key value pair data in a Json format, and uploading the key value pair data to a preset Internet of things platform; when an MQTT protocol message issued by a preset Internet of things platform is received, the MQTT protocol message is converted into binary data based on the preset 104 protocol, and the binary data is issued to equipment corresponding to the MQTT protocol message.
