Detailed Description

The technical solution of the present application will be specifically described below by way of examples with reference to the accompanying drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

It should be noted that: in the present examples, "first", "second", etc. are used for distinguishing similar objects and are not necessarily used for describing a particular order or sequence. The technical means described in the embodiments of the present application may be arbitrarily combined without conflict.

In a public security system, for security and confidentiality, the public security system is usually physically separated from a video network system, but various monitoring devices (such as cameras and capturing machines) are all deployed in the video network, the public security system needs to use data shot by the monitoring devices to operate various services and technical and tactics, in order to obtain the shot data, the public security network usually ferries the data from the video network to the public security network through a network gate, and in order to achieve security, the public security network is generally only allowed to ferry the data to the public security network, and the public security network is not allowed to ferry the data to the video network. A File Transfer Protocol (FTP) server or an FTP storage device needs to be deployed in both the public security network system and the video network system as a storage medium for data.

FTP is an english abbreviation of File Transfer Protocol (File Transfer Protocol), and is one of protocols in the Transmission Control Protocol/Internet Protocol (TCP/IP) Protocol suite. The FTP protocol includes two components, one being an FTP server and the other being an FTP client. The FTP server is used for storing files, and a user can use the FTP client to access resources located on the FTP server through an FTP protocol.

It should be noted that the networks corresponding to the data sending party and the data receiving party in the embodiment of the present application are a video network and a public security network, respectively, but other two networks to which the data transmission method in the embodiment of the present application can be applied should be within the scope of the present application, for example, the networks corresponding to the data sending party and the data receiving party may be a video network and a government network, respectively, or a file network and a public security network, respectively.

In this embodiment, the network corresponding to the data sending party may be an extranet, and the network corresponding to the data receiving party may be an intranet. When the gatekeeper continuously moves data from the external network FTP server to the internal network FTP server, the data consumption program of the internal network may not lift the data files due to faults, so that the residual space of the disk of the internal network FTP server is smaller and smaller, and finally the fault of the internal network FTP server is caused, and the data push program of the external network has no knowledge about the fault, so that the data is continuously pushed, and the data loss may be caused.

Data is a very important resource of a service system, and the normal development of services is seriously affected by data loss, so a scheme is urgently needed to actively protect the system and avoid data loss. In order to solve at least the problems in the related art, embodiments of the present application provide the following data transmission schemes.

Fig. 1 is a schematic architecture diagram of a data transmission system according to an embodiment of the present application, and as shown in fig. 1, the data transmission system 100 includes: a data transmission device 101 and a first storage device 102 in the external network, a gatekeeper 103, and a second storage device 104 and a data reception device 105 in the internal network.

The data sending device 101 may connect to a database and extract relevant data from the database and push the data to the first storage device 102 in the form of a data file. The database may be one or a combination of at least two of a video database, a file database, a voice database, or other database. For example, in the case where the database is a video database, the data transmission apparatus 101 may extract video data from the video database and store the video data in the form of a file in the first storage apparatus 102. In some embodiments, each video file size stored in the first storage device 102 may be a first set size file, or each video file size stored in the first storage device 102 may be a file that is smaller than the first set size. For another example, in the case where the database is a file database, the data transmission apparatus 101 may extract file data from the file database and store the file data in a file of a second set size or less in the first storage apparatus 102.

After the first storage device 102 stores the data file, the gatekeeper 103 may periodically or aperiodically read the data file from the first storage device 102 and ferry the read data file to the second storage device 104.

The data receiving device 105 may read the data file from the second storage device 104 or extract the data file from the second storage device 104 to another storage device connected to the data receiving device 105. In some embodiments, not only may the data receiving device read data from the second storage device, there may be other devices that read data files from the second storage device. When the data receiving device and/or other devices read the data file from the second storage device, in one case, the data file can be read only, the data file is still in the second storage device, and after the read data file is used up, the read data file can be deleted; in another case, the data file may be retrieved and stored in another storage device.

The above description is made on the process of ferrying the data file from the external network to the internal network, and on the basis of the architecture of the data transmission system 100 provided in the embodiment of the present application, the present application may provide the following technical solutions of the data transmission method.

Fig. 2 is a schematic diagram of an implementation flow of a data transmission method provided in an embodiment of the present application, and as shown in fig. 2, the method is applied to a data sending device, and the method includes:

s201, reading a specific state file from a first storage device, wherein the specific state file comprises first quantity information, and the specific state file is read from a second storage device by a gatekeeper and ferred to the first storage device; the first quantity information is used to characterize the quantity of data files stored in the second storage device.

In some embodiments, the first amount information in the particular state file may characterize the amount of data files currently stored in the second storage device. For example, the first amount of information in a particular state file may characterize the amount of data files currently stored in the second storage device at the time the particular state file was generated or created.

The combination of the data transmission device and the first storage device may form a data sender. The data sending device can be a first FTP client, and the first storage device can be a first FTP server. The data transmission device may read the specific state file from the first storage device through the FTP protocol.

The data transmitting device may read the specific state file from the first specific directory of the first storage device. The first specific directory may be a preset directory, which may be used to exclusively store the specific state file, or may store not only the specific state file but also other files such as a data file such as at least one of a video file, an audio file, a document file, and the like.

In some embodiments, the data sending device may read a particular status file from the first storage device every first duration. The first time period may be between 10 seconds and 2 minutes, for example the first time period may be 10 seconds, 1 minute, 2 minutes, or the like. In other embodiments, the data sending device may determine to use different interval durations to read the specific status file according to different actual scenarios. Taking the example that the data sending party sends the video file to the data receiving party, under the scenes of holidays, commuting time and the like, the number of monitored people is large, the monitoring condition needing to be checked by the public security network is also large, and therefore the number of data files sent to the public security network by the video network is increased, and therefore the data party equipment can read the specific state file from the first storage equipment at short time intervals; during the period from morning to morning, fewer scenes need to be monitored by public security screening, so that the specific state file can be read from the first storage space at longer time intervals.

In some embodiments, the particular state file may include: the first amount of information. In other embodiments, the particular state file may include not only the first amount of information, but also other information, which may include at least one of: first connection state information between the data reception device and the second storage device, a type of the specific state file, attribute information of the specific state file, a first specific number, attribute information of the second storage device, attribute information of the data reception device, and the like.

The specific state file in the embodiment of the present application may be an FTP file. In other embodiments, the particular state file may be a file in other formats, such as HyperText Transfer Protocol (HTTP), and the like.

The specific state file may be generated by a data receiver of the intranet. For example, in some embodiments, a data receiving device of a data recipient may determine first amount information of data files stored in a second storage device connected to the data receiving device, and generate a particular state file based on the first amount information.

In some embodiments, the data receiving device generating the particular state file based on the first amount of information may include: and writing the first quantity information into the first temporary file to obtain a second temporary file, wherein both the first temporary file and the second temporary file are files which cannot be read by the gatekeeper, and then performing format conversion on the second temporary file to obtain a specific state file which is a file which can be read by the gatekeeper.

In other embodiments, the data receiving device generating the particular state file based on the first amount of information may include: generating a target file, and writing the first amount of information into the target file to obtain a specific state file; wherein the target file is a file capable of being read by the gatekeeper.

The first temporary file and/or the target file may be a blank file having a certain format or a file having a certain format and attribute class information so that the data receiving apparatus can write the related information including the first amount of information into the corresponding attribute class.

The file size of a particular state file may be in the range of 10 to 100 bytes, for example, the file size of a particular state file may be 10 bytes, 50 bytes, 100 bytes, or the like. In some embodiments, the gatekeeper may support a file filtering function, for example, the gatekeeper may filter the status file in the second storage device, so that the gatekeeper may only read the status file in the second storage device whose file size is smaller than or equal to a specific byte, which may be in a range of 10 to 100 bytes, for example, which may be 10 bytes, 50 bytes, or 100 bytes, etc. The state file in the specific byte is ferried from the internal network to the external network through the network gate, and even under the condition of information leakage, little data is leaked, so that the data safety is influenced as little as possible.

In some embodiments, the file extension (filename extension) of a particular state file may be ". stat". The file corresponding to the file extension ". stat" is a file that can be read by the gatekeeper. The first amount information in the specific state file may be in json (javascript Object notification) format. In other embodiments, the file extension of the specific state file may be other, or the first amount of information may be encapsulated in other formats, which is not limited in this embodiment.

The network gate is an information safety device which uses a solid-state switch read-write medium with multiple control functions to connect two independent host systems. Because two independent host systems are isolated through the gatekeeper, no physical connection, logical connection and information transmission protocol for communication exist between the systems, no information exchange according to the protocol exists, and only no protocol ferry is performed in a data file form.

The data files stored in the second storage device may be data files stored in a second specific directory in the second storage device. The second specific directory may be a preset directory.

Without specific description, the file extension of the data file in the embodiment of the present application may be ". bak", and the file corresponding to ". bak" may be a backup file. Without being particularly described, the data file may be a file having a file size smaller than or equal to a specific size, and the specific size may be a predefined size.

S202, under the condition that the first quantity information is smaller than the first specific quantity, pushing a data file to the first storage device; the data file in the first storage device is used for: the network gate reads and ferries the data to a second storage device; the data file in the second storage device is used for: and reading by the data receiving device.

And the pushed data file is read by the gateway and ferred to the second storage device, so that the data receiving device can read the pushed data file from the second storage device.

The first specific number may be pre-stored in the data transmitting device or the first storage device. The first specific amount may be determined according to a storage capacity size of the second storage device, or according to a storage capacity size under a second specific directory in the second storage device. In this embodiment, the storage size occupied by the data file in the second storage device or in the second specific directory of the second storage device may be predicted by the first quantity information, for example, the size of the data file is defined to be less than or equal to a Megabytes (MB), and when the first quantity information is B, the data sending device may determine the storage size occupied by the data file in the second specific directory of the second storage device to be less than or equal to a × B Megabytes. By determining whether the first quantity information is smaller than the first specific quantity, it can be determined whether the storage size occupied by the data files in the second specific directory in the second storage device is smaller than a specific storage size. If the occupied storage size is larger than or equal to the specific storage size, the remaining storage space of the second storage device is smaller, and the data sending device can stop pushing the data file to the first storage device; if the occupied storage size is smaller than the specific storage size, the remaining storage space of the second storage device is larger, and the data sending device can continue to push the data file to the first storage device.

The gatekeeper can transport a specific state file or data file from one side to the other side in the case of ferrying the specific state file or data file, or can transport a copied file to the other side after copying the specific state file or data file on one side.

In the embodiment of the application, the data sending device can determine the first quantity information of the data files in the second storage device of the data receiving party, so that the second storage device can receive the data files under the condition that the first quantity information is smaller than the first specific quantity, the data files can be pushed to the first storage device, and the situation that the data files are easy to lose due to the fact that the data files are pushed to the first storage device when the second storage device does not receive the data files under the condition that the first quantity information is smaller than the first specific quantity information is avoided.

In some implementation scenarios, in order to ensure data security as much as possible, the system may prohibit the gatekeeper from ferrying data from the internal network to the external network, in this case, in order to avoid data loss as much as possible, the data transmission method may be implemented by the embodiment corresponding to fig. 3:

fig. 3 is a schematic implementation flow diagram of another data transmission method provided in the embodiment of the present application, and as shown in fig. 3, the method is applied to a data sending device, and the method includes:

s301, determining second quantity information of the data files stored in the first storage device.

In some embodiments, the data transmitting device may determine the second quantity information every second duration. The first duration of the interval between reading a particular state file may be greater than or equal to the second duration. The second time period may be between 5 seconds and 1 minute, for example, the second time period may be 5 seconds, 10 seconds, 30 seconds, 1 minute, or the like. In other embodiments, the data transmitting device may determine the second amount of information by determining different interval durations according to different actual scenarios. The interval duration of the second quantity of information may be determined to be positively correlated with the interval duration of reading the specific status file.

S302, pushing data files to a first storage device under the condition that the second quantity information is smaller than a second specific quantity, wherein the data files in the first storage device are used for: the network gate reads and ferries the data to a second storage device; the data file in the second storage device is used for: and reading by the data receiving device.

The second specific number may be pre-stored in the data transmitting device or the first storage device. The second specific amount may be determined based on a storage capacity size of the first storage device, or based on a storage capacity size of the first storage device under the first specific directory. In the embodiment of the present application, the storage size occupied by the data file in the first storage device or in the first specific directory of the first storage device may be predicted through the second quantity information.
