Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
In order to solve the problems of data loss caused by terminal equipment offline, gateway equipment offline and gateway equipment crash, the application aims to solve the problem of data loss caused by various abnormal scenes in the background of short-time data storage of a data terminal, temporary data storage of a data gateway and permanent data storage of a server by an automatic supplementary transmission method and a manual supplementary transmission method so as to improve the high availability and the data integrity of a platform.
Specifically, referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart of an embodiment of a data transmission method provided in the present application, and fig. 2 is a schematic flowchart of an automatic supplementary transmission of the data transmission method provided in the present application. The data transmission method is applied to a data transmission system, the data transmission system comprises terminal equipment, a data gateway and a server, the data gateway is in communication connection with the terminal equipment and the server respectively, and the data gateway can transmit data uploaded by the terminal equipment to the server for storage. In the data transmission system of the embodiment of the application, the terminal device can store the short-time data, the data gateway can store the temporary data, and the server can store the permanent data.
As shown in fig. 1, the data transmission method according to the embodiment of the present application may specifically include the following steps:
step S11: and the server receives the data uploaded by the data gateway and records the first time when the data are successfully uploaded.
In the embodiment of the application, the terminal device continuously uploads the data to the data gateway, and the data gateway uploads the data to the server. When the server successfully receives the data uploaded by the data gateway, the server records the first time when the data gateway successfully uploads the data.
It should be noted that, in the data transmission system according to the embodiment of the present application, a plurality of data gateways and a plurality of terminal devices may be included; the communication connection relationship between the terminal device and the data gateway may be one-to-one or many-to-one, which is not limited herein.
For the same data gateway, the server may record a plurality of first times of the data gateway, or may record only the latest first time of the data gateway, that is, when the latest first time is recorded, the previous first time is covered, so as to continuously update the latest time of successfully uploading data of the data gateway.
Step S12: and the server detects whether the data gateway is in a normal working state, and if not, sets the latest first time as first retransmission time.
In the embodiment of the application, in the data transmission process, the server detects whether the data gateway is in a normal working state or not through a keep-alive message technology, namely whether data can be normally transmitted or not. Specifically, heartbeat detection can be established between the server and the data gateway, the server continuously sends heartbeat information to the data gateway, and when response information returned by the data gateway based on the heartbeat information is not acquired within a preset time, the server side can determine that the data gateway is not in a normal working state, and an offline condition or a breakdown condition and the like may occur.
When the server detects that the data gateway is in a normal working state, the server can continuously receive data from the data gateway; when the server detects that the data gateway is not in a normal working state, the server acquires the latest first time recorded by the data gateway and sets the latest first time as the first retransmission time of the data gateway.
Step S13: after the first retransmission time is set, the server continues to detect whether the data gateway is in a normal working state, and if so, the time for switching the data gateway to the normal working state is set as second retransmission time.
In the embodiment of the application, after the data gateway is determined to be switched from the normal working state to the abnormal working state and the first retransmission time is set, the server continues to detect whether the data gateway is offline and then is on-line again by using the keep-alive message, that is, the data gateway is switched from the abnormal working state to the normal working state. When the server detects that the data gateway is on-line again, and the server of the data gateway is confirmed to be restarted successfully through the registration information of the data gateway, the server can continue to perform data transmission, the time for switching the data gateway to the normal working state is set as the second retransmission time of the data gateway, and the step S14 can be entered.
Step S14: and the server sends a retransmission instruction to the terminal equipment and/or the data gateway based on the first retransmission time and the second retransmission time.
In the embodiment of the application, the server generates the retransmission instruction based on the first retransmission time and the second retransmission time. Specifically, the retransmission instruction specifies a time period during which the data gateway cannot upload data to the server due to an abnormal condition, and the time period is determined by the first retransmission time and the second retransmission time recorded by the server. The terminal device and/or the data gateway can upload the data again from the respective local database according to the time period specified by the retransmission instruction.
In the embodiment of the application, the data which needs to be uploaded again by the data gateway or the terminal device is specified by the first retransmission time and the second retransmission time recorded by the server, so that the efficiency of uploading the data can be effectively improved, and the transmission of repeated data is reduced on the premise of ensuring the integrity of the data.
Step S15: and the terminal equipment and/or the data gateway uploads the data based on the retransmission instruction.
In the embodiment of the present application, as shown in fig. 2, there are two ways of data retransmission, one is to directly retransmit data by a data gateway, and the other is to retransmit data to the data gateway by a terminal device, so that the data gateway retransmits the data.
Firstly, a method for directly retransmitting data by a data gateway is introduced:
the data gateway can also detect whether the data link between the data gateway and the server is abnormal through the protection message, and when the data link is abnormal, the data gateway can temporarily store data uploaded by the terminal equipment to a local database, so that the function of storing temporary data by the data gateway is realized.
Based on the function that the data gateway can store temporary data, the server sends a retransmission instruction to the data gateway, and the data gateway performs the task of data retransmission.
Specifically, the data gateway detects whether the relevant data is stored in the local database based on the time period specified by the retransmission instruction. If the data specified by the retransmission instruction is stored in the local database, the data gateway uploads the data specified by the retransmission instruction to the server again; if the data specified by the retransmission instruction is not stored in the local database, the data gateway may issue the retransmission instruction to the terminal device, and the terminal device retransmits the data specified by the retransmission instruction.
Further, if a part of data specified by the retransmission instruction is stored in the local database of the data gateway, the data gateway may directly upload the part of data to the server again, generate a new retransmission instruction based on the remaining data specified by the retransmission instruction, and upload, by the terminal device, the part of data not stored in the local database of the data gateway according to the new retransmission instruction. In addition, if the local database of the data gateway stores part of the data specified by the retransmission instruction, the data gateway may also directly issue the retransmission instruction to the terminal device, and the terminal device retransmits all the data specified by the retransmission instruction.
Next, the manner in which the terminal device retransmits data to the data gateway and then the data gateway retransmits the data is described:
the server directly issues the retransmission instruction to the terminal equipment, or issues the retransmission instruction to the data gateway, and the retransmission instruction is forwarded to the terminal equipment by the data gateway. And after receiving the retransmission instruction, the terminal equipment searches the data specified by the retransmission instruction in the local database and uploads the data to the server again through the data gateway.
In the embodiment of the application, a server receives data uploaded by a data gateway and records first time when the data is successfully uploaded; the server detects whether the data gateway is in a normal working state, and if not, the latest first time is set as first retransmission time; the server continuously detects whether the data gateway is in a normal working state, if so, the time for switching the data gateway to the normal working state is set as second retransmission time; the server sends a retransmission instruction to the terminal equipment and/or the data gateway based on the first retransmission time and the second retransmission time; and the terminal equipment and/or the data gateway uploads data based on the retransmission instruction. The data transmission method can provide a feasible data retransmission mode aiming at various abnormal conditions in data transmission, and improves the completeness of data output and the high availability of service.
Referring to fig. 3 and fig. 4, fig. 3 is a schematic flowchart of another embodiment of the data transmission method provided by the present application, and fig. 4 is a schematic flowchart of a manual supplementary transmission of the data transmission method provided by the present application.
As shown in fig. 4, the difference between the automatic retransmission function and the manual retransmission function of the data transmission method provided in the embodiment of the present application mainly lies in: in the automatic transmission supplementing function, when the data gateway uploads again and the service is restarted successfully, the server automatically generates and issues a retransmission instruction; in the manual retransmission function, the user can manually trigger the retransmission instruction according to the will of the user, and the time period specified by the retransmission instruction can also be freely configured according to the will of the user. Please refer to the specific steps of the data transmission method shown in fig. 3:
step S21: and the server responds to the configuration instruction of the user and generates a retransmission instruction according to the configuration time in the configuration instruction.
In the embodiment of the application, a user can select a terminal device and/or a data gateway for re-uploading data and a retransmission time period in a server configuration page, trigger a data retransmission function, and generate a retransmission instruction according to a configuration result of the user.
Specifically, the time period specified by the retransmission instruction can be freely configured by the user, and in order to improve the efficiency of retransmission, the data retransmission time period can also be determined by referring to the time configured by the user and the retransmission time recorded by the server. For example, the server records three points in time, including: configuration time of a user, first retransmission time and second retransmission time. In a case that the three time points do not coincide with each other, at least six time periods may be generated, and for this, in order to ensure integrity of the data, the server may adopt a time period with the longest time among the at least six time periods as a data retransmission time period.
In other embodiments, other time periods of the at least six time periods may also be adopted, which is not described herein again.
Step S22: and the terminal equipment and/or the data gateway specified by the configuration instruction uploads data based on the retransmission instruction.
In the embodiment of the application, the terminal device and/or the data gateway specified by the user in the server configuration page re-uploads the data corresponding to the time period based on the data retransmission time period specified by the retransmission instruction.
Because the configuration of the transmission mode of manual supplementary transmission is flexible, the server can also perform deduplication processing on retransmitted data, thereby ensuring complete and efficient data storage. Therefore, please continue to refer to the following steps:
step S23: and the server acquires retransmission data uploaded by the terminal equipment and/or the data gateway based on the retransmission instruction.
Step S24: and the server checks the retransmitted data and the received data for duplication and deletes the data which is duplicated with the received data in the retransmitted data.
In the embodiment of the present application, the data duplication checking manner may be a comparison of the data itself, or a comparison of timestamps corresponding to the data. In this regard, the embodiment of the present application does not limit the manner of data duplicate checking.
Step S25: and the server stores the deleted retransmission data to a local database of the server.
In the embodiment of the application, the data transmission system combines the storage characteristics of the terminal device and the data gateway, and provides two methods of automatic supplementary transmission and manual supplementary transmission to solve various abnormal conditions in data transmission, so that the behavior of discarding data under the traditional conditions such as network abnormality, software failure, server power failure, server downtime and the like is changed, and the completeness of data and the high availability of service are improved.
