Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail and completely with reference to the following embodiments and accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a data transmission method, where the method includes:
and step 14, transmitting the uploading data to the EMQ server so that the cloud end subscribes to the uploading data in the EMQ server.
In the above embodiment, the notification instruction transmitted by the cloud is subscribed to an EMQ server (Erlang/Enterprise/Elastic MQTT Broker, an open-source internet of things MQTT message server developed based on an Erlang/OTP platform), then the authentication information of the notification instruction is determined, whether the authentication information meets the preset condition is determined, if the authentication information meets the preset condition, the upload data is determined according to the notification instruction, the upload data is transmitted to the EMQ server, and the cloud acquires the acquisition data of the edge end by subscribing the upload data in the EMQ server. The technical scheme that this embodiment provided transmits the data of high in the clouds and edge through the EMQ server to avoid directly uploading the edge data to the high in the clouds, even when the data bulk is great, the condition of data blocking can not appear yet, and make the high in the clouds and the edge all can carry out the chosing of content through the subscription mode of EMQ server, and then improve data transmission efficiency.
It should be noted that the EMQ server has both the notification instruction transmitted by the cloud and the upload data of the edge, the edge can subscribe the notification instruction in the EMQ server, select the notification instruction executable by the edge to execute, the cloud subscribes the upload data in the EMQ server, selects the data that the cloud is interested in, and pulls the selected data to the cloud.
In an embodiment, if the authentication information meets a preset condition, a notification confirmation receipt is transmitted to the EMQ server, so that the EMQ server transmits the notification confirmation receipt to the cloud through a proxy server. In the above embodiment, the notification instruction transmitted by the cloud is executed by the edge end through the authentication information, so as to increase the security of data transmission, where the preset condition may be that the authentication information exists, and therefore, when the authentication information exists in the notification instruction, that is, the authentication information meets the preset condition, the notification instruction needs to be executed to determine to upload data. Certainly, the preset condition may also be some predetermined information with identification, and the security index of the authentication information is increased, if the authentication information carries a specific character string, the authentication information only carries the specific character string in the notification instruction and meets the preset condition. If the authentication information does not meet the preset condition, the content of the notification instruction is not executed, and at this time, the edge terminal can re-subscribe the notification instruction to the EMQ server to perform subsequent operations according to the new notification instruction. Due to the existence of the EMQ server, the data transmission between the cloud end and the edge end is not synchronous any more, namely the data transmission between the cloud end and the edge end is asynchronous, so that the cloud end and the edge end are required to timely feed back information in order to enable the cloud end and the edge end to mutually know the data transmission process. The method comprises the steps that a notification instruction is subscribed at an edge terminal, and after the notification instruction meets a preset condition, the edge terminal transmits a notification confirmation receipt to an EMQ server through an MQTT (Message queue Telemetry Transport) protocol, the notification confirmation receipt can enable a cloud terminal to know that the edge terminal receives the notification instruction, when the EMQ server transmits the notification confirmation receipt to the cloud terminal, the notification confirmation receipt is transmitted to a proxy server through the MQTT protocol, and then the proxy server transmits the notification confirmation receipt to the cloud terminal through an HTTP protocol. The proxy server refers to a server for data interaction with the EMQ server.
In an embodiment of the present invention, when the upload data is transmitted to the EMQ server, an HTTP Protocol (Hypertext Transfer Protocol) is used to upload the data, after the EMQ server obtains the upload data, the upload data is transmitted to the proxy server, and the proxy server transmits the upload data to the database, so as to ensure that the upload data in the EMQ server can be timely stored in the database, thereby ensuring the integrity and timeliness of the data in the database.
In a possible application scenario, the edge is an equipment end in the energy system, and energy data transmission is performed to the cloud end through the EMQ server, so that a large amount of energy data can be transmitted to the cloud end through the EMQ server under the condition that data blockage is not caused. Different notification instructions correspond to different contents, for example, when a certain notification instruction is executed, the uploaded data is the energy data acquired in the last month, and when another notification instruction is executed, the uploaded data is the energy data acquired in the last week. Of course, the uploaded data may be determined as the fault data within a preset time period (within one month) by the notification instruction, so that the corresponding data is the fault database when the fault data is transmitted to the database through the EMQ server and the proxy server.
As shown in fig. 2, in an embodiment of the present invention, the method further includes:
and step 16, transmitting the data uploading state to the EMQ server, so that the EMQ server transmits the data uploading state to the cloud end through a proxy server.
In the above embodiment, the edge needs to determine a data upload state, where the data upload state includes a data upload success and a data upload failure, and after determining the data upload state, the edge transmits the data upload state to the EMQ server, so that the EMQ server transmits the data upload state to the cloud via the proxy server, and after receiving the data upload state, the cloud determines that the data upload of the edge is successful or failed, so that the cloud knows the data upload condition of the edge in time. And when the cloud determines that the edge data is successfully uploaded according to the data uploading state, the cloud subscribes the uploaded data to the EMQ server. In one possible case, after receiving the data uploading state, the cloud determines the receipt information again according to the data uploading state, and transmits the receipt information to the edge end through the EMQ server, so that the edge end can master the progress of the cloud.
As shown in fig. 3, in an embodiment of the present invention, the method further includes:
In the above embodiment, if there is a configuration change at the edge, the cloud needs to know the configuration change at the edge in time, so that when there is a configuration change at the edge, the configuration change state is determined, where the configuration change state includes a success or failure of the configuration change, the edge transmits the configuration change state to the EMQ server through an MQTT protocol, the EMQ server transmits the configuration change state to the proxy server through the MQTT protocol, and the proxy server transmits the configuration change state to the cloud through an HTTP protocol, so that the cloud knows the configuration change condition at the edge. In one possible implementation, the edge may perform configuration changes based on notification instructions transmitted from the cloud subscribed to by the EMQ server.
Based on the same inventive concept as the above method, as shown in fig. 4, an embodiment of the present invention provides a data transmission apparatus, including:
the instruction acquisition module 41 is configured to subscribe a notification instruction transmitted by the cloud to the EMQ server;
an information determining module 42, configured to determine authentication information of the notification instruction;
