Detailed Description

The following detailed description will be provided with reference to the accompanying drawings and embodiments, so that how to apply the technical means to solve the technical problems and achieve the corresponding technical effects can be fully understood and implemented. The embodiments and various features in the embodiments of the present application can be combined with each other on the premise of no conflict, and the formed technical solutions are all within the protection scope of the present application.

Example one

Fig. 1 is a flowchart of a data backup method provided in an embodiment of the present application, and as shown in fig. 1, the method of the present embodiment includes:

and S110, under the condition that the network abnormality is detected, storing data which is sent by the connected equipment and is not synchronized to the target server.

In some cases, under a normal network condition, before adding a device, it is necessary to determine whether there is locally unsynchronized data that has not been sent to the target server due to a network outage, and when there is unsynchronized data, it is necessary to send the unsynchronized data to the target server first, and delete the unsynchronized data after the synchronization is successful.

Optionally, when adding the device, first add basic information (including asset information, manufacturer information, usage units, production lines, posts, etc.) of the device, and then add connection configuration and debugging information (including connection mode, resolution protocol, etc.) of the device.

Optionally, after the device is added, the device needs to be debugged according to the connection configuration and the debugging information corresponding to the device. For example, the corresponding resolution protocol of the device is selected to start debugging the device, to check whether the data of the device can be normally received, and/or to check whether the device can normally receive and execute the instructions sent by other systems. If the resolution protocol has problems, the debugging process is abnormal, and at the moment, the equipment needs to be debugged again until the debugging is successful. The user can be reminded when an abnormality occurs in the debugging process, and the user can select to replace the analysis protocol to continue debugging or stop debugging.

Optionally, after the device is successfully debugged, the step of adding the device may be further performed.

In some embodiments, further comprising:

Optionally, when a server is added, basic information (including a system name, an IP, a port number, an account number, and a password) of the server needs to be set.

Optionally, when an instruction to add a server is detected, other systems, message middleware, etc. may also be added.

For example, the message middleware may be a RabbitMQ (as will be understood by those skilled in the art, a RabbitMQ is an open source message agent software that implements an advanced message queuing protocol, also referred to as message-oriented middleware); other systems may include a first system and a second system, for example, the first system may include a detection system that may receive detection data for the device; the second system may include a Glink device management system, and the connected devices may communicate with each other through RabbitMQ, for example, sending a firmware update instruction to the connected devices in the form of a RabbitMQ message to enable the corresponding devices to perform a firmware update operation, and also sending other instructions to be able to update related information of the devices managed by the Glink device management system.

It should be noted that basic information of the server must be set first, and then the connected device can communicate with the server according to a certain rule (for example, send data to be synchronized to the server).

In some embodiments, the data sent by the connected device is parsed via a preset parsing protocol before being synchronized to a target server or stored.

Optionally, the preset parsing protocol may be a mainstream parsing protocol, or may be a user-defined parsing protocol, and only the relevant basic information and the parsing protocol need to be simply configured when the device is connected.

Optionally, before the storing the data that is sent by the connected device and is not synchronized to the target server under the condition that the network anomaly is detected, the method further includes:

under the condition that the network is normal, analyzing data sent by connected equipment to obtain analyzed data;

and storing the analysis data into a preset data table of a local database, and simultaneously sending the analysis data to a server.

In some cases, the time when the connected device sends data may be saved in a preset time data table of the local database at the same time as the parsing data is saved in a preset data table of the local database. When synchronizing data to the server, the time data stored in the preset time data table of the local database and the analysis data stored in the preset data table of the local database may be transmitted to the server together.

Optionally, the preset data table may be a data backup table in the local database, and may be specifically set according to the actual requirement of the user.

Optionally, after the storing the analysis data in a preset data table and sending the analysis data to a server, the method further includes:

and clearing the preset data table.

Optionally, under a normal network condition, the data sent by the connected device is firstly analyzed to obtain analyzed data (data that is not sent to the target server), the analyzed data is stored in a preset data table in the local database, then the time for the connected device to send the unsynchronized data is also stored in the preset data table in the local database, finally the analyzed data is synchronized to the server, and the data stored in the preset data table in the local database is deleted after the synchronization is successful.

Optionally, the data may be processed when the data sent by another system is received, if the data needs to be communicated with a connected device, the device to be communicated may be found according to the corresponding rule, and the instruction may be forwarded to the device, and if the instruction fails to be sent, the error type may be identified and a warning message may be sent to the user; after receiving data sent by connected equipment, analyzing the data to obtain analyzed data, storing the analyzed data into a local database, and then sending the analyzed data to a server according to a certain rule.

It should be noted that, when there are multiple connected devices, the data that needs to be backed up by each device may be stored in the same table in the local database, or may be separately stored in a table corresponding to each device, and the data may be specifically set according to actual requirements.

Optionally, a heartbeat detection mechanism (regularly sending a request) is used to determine whether the network is abnormal, for example, the request is abnormal or the data reception is abnormal, and the client is considered to be disconnected.

It should be noted that, the connected device and the server can communicate through the message middleware RabbitMQ, which ensures that data arriving at the RabbitMQ cannot be lost even if the network is disconnected.

In some cases, the server and the user terminal can be connected with the user terminal, the server and the user terminal can publish and subscribe RabbitMQ messages, the client needs to perform corresponding verification when receiving the messages, and the messages are processed after the verification is passed, so that the security of the data of the Internet of things is enhanced. Subscribers who subscribe to a certain type of message receive the corresponding message and then do corresponding actions according to the message content.

Optionally, after synchronizing the data sent by the connected device to the server, the data stored locally in the preset data table of the database needs to be cleared.

For example, if there are devices accessing through the lan, when a network disconnection occurs, it will be prompted to "how is the lan disconnected, there are 2 devices (device 1, device 2) connected through the lan and whether to modify the access mode? If no, the user knows that the two devices are not the devices in use and does not need to modify the connection mode; if the equipment is selected to be debugged, the equipment needs to be correspondingly modified, a modification button is clicked to an equipment entry page of 103, corresponding equipment is found according to equipment information, connection is carried out through wires such as a serial port, then equipment connection mode information is modified on the page, and the equipment is debugged continuously 104.

It should be noted that the method disclosed in this embodiment may be applied to a server, an industrial PC (Personal computer), a device, and the like in a manufacturing enterprise to implement mutual communication, and on the premise of ensuring data integrity, an industrial manufacturing internet of things is implemented, and the connection mode of the device may include wired access (for example, a USB interface, a serial port, an ethernet interface, and the like) and wireless access (for example, bluetooth, NFC, and the like), and supports multiple access modes when connecting the device, and meanwhile, facilitates quick switching of the connection mode when the network is disconnected.

And S120, sending the data which is not synchronized to the target server under the condition that the network is detected to be recovered to be normal.

Optionally, when it is detected that the network is recovered to normal, the data in the preset data table of the local database is sent to the target server (for example, the corresponding unsynchronized data is pushed to a delay queue of the server), so that a situation that data being propagated in the network is lost due to network outage is avoided, and the integrity of the data is ensured.

It should be noted that, in order to further improve the efficiency of data synchronization, in some cases, the step of frequently executing "determining whether there is unsynchronized data in the preset data table of the local database" may be instantiated as a tool class, the result of "determining whether there is unsynchronized data" is used as a value in the tool class, only the cache value needs to be updated each time the unsynchronized data is added and emptied, and database query is not needed when determining whether there is unsynchronized data locally, which improves the efficiency.

Meanwhile, to facilitate understanding of the technical solution of the present application, reference may also be made to fig. 2, and fig. 2 is a schematic flow chart of data backup provided in the embodiment of the present application.

Compared with the traditional intelligent internet of things gateway, the data backup method provided by the embodiment only needs to simply configure the corresponding equipment or server, stores the data collected by the equipment blocked due to the network interruption after the network interruption condition is identified, and automatically continues to transmit the blocked data when the network restoration condition is identified. Specifically, the method comprises the following steps: under the condition that the network abnormality is detected, data which are sent by connected equipment and are not synchronized to a target server are stored; and under the condition that the network is detected to be recovered to normal, sending the data which is not synchronized to the target server. According to the technical scheme, system LAN abnormity can be automatically identified, early warning can be carried out on equipment with network faults to a user, and the integrity of data collected by the equipment is guaranteed to the maximum extent.
