The terms "first," "second," and the like, are used solely to distinguish one entity or action from another entity or action without necessarily being construed as indicating or implying any actual such relationship or order between such entities or actions.
It should be noted that the data transmission method provided in the embodiments of the present application may be executed by an electronic device, where the electronic device refers to a device terminal or a server having a function of executing a computer program, and the device terminal includes, for example: personal Computers (PCs), tablet computers, Personal Digital Assistants (PDAs), Mobile Internet Devices (MIDs), network switches or network routers, etc.
Before introducing the data transmission method provided in the embodiment of the present application, an application scenario applicable to the data transmission method is introduced, where the application scenario includes, but is not limited to: in the data transmission process of the internal network and the external network of the hospital system, as the unidirectional network strategy is adopted and the network gate is arranged between the internal network and the external network, the data transmission of the internal network and the external network can only be transmitted in a unidirectional way and is limited by the influence of the network gate. Therefore, the data transmission method can be used for transmitting the data in the internal network temporary storage module to the external network temporary storage module to provide downloading use for the terminal connected with the external network when the network is stable, and pulling the data in the external network temporary storage module to the internal network temporary storage module to provide entry downloading use for the terminal connected with the internal network, so that even if the network is unstable or the network gate is closed, the data in the internal network is transmitted to the external network temporary storage module and the internal network temporary storage module when the network is stable, and the influence of the network instability and the network gate closing on the data transmission can be reduced. Referring to fig. 1, fig. 1 is a schematic diagram of terminal interaction of a data transmission method according to an embodiment of the present application; the terminal of connecting the intranet in figure 1 can carry out data interaction (send intranet data or download extranet data) to intranet temporary storage module, and intranet temporary storage module can send the data of sending internally or pull extranet data to extranet temporary storage module, and the terminal of connecting the extranet can carry out data interaction (send extranet data or download extranet data) with extranet temporary storage module.
Referring to fig. 2, fig. 2 is a schematic flow chart of a data transmission method according to an embodiment of the present application, where the data transmission method includes:
step S100: and receiving intranet data sent by the terminal connected with the intranet.
Step S200: and storing the intranet data by using an intranet temporary storage module.
Step S300: monitoring whether the data transmission network is stable.
It should be noted that, in the above step S300, in a preferred embodiment, the monitoring whether the data transmission network is stable by using the scheduler includes: monitoring whether the gatekeeper is opened and/or whether the network state of the data transmission network can meet the data transmission requirement.
If the data transmission network is stable, step S400 is executed: and sending the intranet data to the extranet temporary storage module, and storing the intranet data by using the extranet temporary storage module.
It should be noted that, in the step S400, the intranet data in the extranet temporary storage module may be downloaded by the terminal connected to the extranet.
In the implementation process, the data in the internal network temporary storage module is transmitted to the external network temporary storage module to be stored for standby when the network is stable, and even if the network is unstable or the network gate is closed, the data in the internal network is transmitted to the external network temporary storage module to be downloaded and used by the terminal of the external network when the network is stable, so that the influence on data transmission due to the instability of the network and the closing of the network gate can be reduced.
In some optional embodiments, before sending the intranet data to the extranet temporary storage module, the method further includes: cutting the intranet data according to the preset maximum file size to obtain a plurality of data slices of the intranet data; send intranet data to outer net module of keeping in, include: sending data slices of the intranet data to an intranet temporary storage module, and carrying out integrity check on the data slices of each intranet data; and recombining the plurality of data slices of the intranet data to obtain the intranet data.
It can be understood that, in practical applications, there is a limit to the size of data to be transmitted, and if the data is large, the data cannot be transmitted in advance, so that the data exceeding the maximum file size can be transmitted after being sliced before the data is transmitted. Specifically, for example, the maximum file allowed by data transmission is 30M, but in the specific transmission, the size of one data is 50M, and if the data is directly transmitted, the data transmission will fail, so that before data transmission, the data entry can be cut, and two data slices divided into 30M and 20M are transmitted, thereby ensuring that data transmission failure cannot be caused by too large data.
In some optional embodiments, performing integrity check on the data slice of each intranet data includes: and if the data slice of the intranet data is incomplete, retransmitting the data slice.
Specifically, in the implementation process, integrity check is performed on all successfully transmitted intranet data to ensure the integrity of the transmitted data slice, and the condition that the transmission of the data slice is incomplete and the recombined data is incomplete is avoided. In a preferred embodiment, sha1 verification may be performed on the intranet data.
In some optional embodiments, the intranet data slice may be encrypted before being encrypted to increase the security of the data.
In some optional embodiments, the method further comprises: and if the data transmission network is stable, pulling the extranet data in the extranet temporary storage module, and uploading the extranet data by a terminal connected with the extranet.
In the implementation process, it can be understood that the extranet data is uploaded to the extranet temporary storage module by the terminal connected to the extranet, but the extranet data in the extranet temporary storage module cannot be actively pushed to the intranet due to the unidirectional network policy. Therefore, the mode that the intranet actively pulls the extranet data in the extranet temporary storage module can be adopted when the network is stable, the extranet data are stored in the intranet temporary storage module, the influence of a unidirectional network strategy on data transmission is avoided, meanwhile, the extranet data are stored in the intranet temporary storage module to be downloaded and used by a terminal connected with the intranet, and the influence caused by closing of a network gate or instability of the network can be reduced.
In some optional embodiments, optionally, in an embodiment of the present application, the intranet temporary storage module includes a plurality of intranet temporary storage units, and the plurality of intranet temporary storage units correspond to terminals connected to the extranet; receiving intranet data sent by an intranet-connected terminal includes: acquiring a target intranet temporary storage unit in an intranet temporary storage module; sending intranet data to a target intranet temporary storage unit; use intranet module of keeping in storage to intranet data includes: storing intranet data by using a target intranet temporary storage unit; send the intranet data to outer net module of keeping in to use outer net module of keeping in to save the intranet data, include: matching a target outer network temporary storage module corresponding to the target inner network temporary storage unit, wherein the target outer network temporary storage module is selected from one of a plurality of outer network temporary storage modules; and sending the intranet data to the target extranet temporary storage module, and storing the intranet data by using the target extranet temporary storage module.
In the above-mentioned realization process, probably including the terminal with a plurality of connection extranets, consequently can be divided into a plurality of and be connected the intranet temporary storage unit that the extranet corresponds with intranet temporary storage module, at data transmission in-process, with intranet data according to the terminal of being connected with the extranet respectively save with different intranet temporary storage units, thereby different temporary storage units can only send intranet data to the extranet temporary storage module that corresponds thereby increased data transmission's flexibility, accuracy and security.
In some optional embodiments, wherein pulling the extranet data in the extranet staging module includes: pulling the extranet data in the target pull temporary storage module, wherein the target pull temporary storage module is selected from one of the extranet temporary storage modules; and matching the corresponding intranet temporary storage unit according to the pulled extranet temporary storage module and storing extranet data pulled in the target pulled temporary storage module into the intranet temporary storage unit.
In the above-mentioned implementation process, when pulling extranet data, because the intranet temporary storage unit of intranet temporary storage module can only pull the extranet data in the corresponding extranet temporary storage module, consequently need pull the target and get temporary storage module and intranet temporary storage module and match, can increase the accuracy that data were pulled and the security of data transmission through above-mentioned mode.
In a preferred embodiment, the extranet temporary storage module may be divided into different extranet temporary storage units according to different intranet-connected terminals, and when the extranet data is uploaded by an extranet-connected terminal, the intranet-connected terminal corresponding to the extranet data is first obtained, and then the extranet data uploaded by the extranet-connected terminal according to the intranet-connected terminal is stored in the corresponding extranet temporary storage unit.
In the above implementation process, it can be understood that each terminal device connected to the intranet corresponds to a different intranet temporary storage module, and the data of each extranet temporary storage unit can only be pulled by the corresponding intranet temporary storage module, so that the security and flexibility of the data in the data pulling process can be increased.
For ease of understanding, the implementation of the above method is described below with hospital and pharmaceutical manufacturer data transmission as an example. In hospital data transmission, terminals of all hospitals are used as terminals for connecting an internal network, and terminals of pharmaceutical manufacturers are used as terminals for connecting an external network. In the present example, each hospital has a cooperation relationship with each pharmaceutical manufacturer (i.e., data interaction is required), and it can be understood that, due to the difference of cooperation contents, the confidential terms and the data that can be provided by the hospital for different manufacturers are not completely the same, so that the data transmission can be performed by using the above method for accurately transmitting data.
Referring to fig. 3, fig. 3 is a schematic diagram of a first terminal interaction provided in the embodiment of the present application, which is exemplarily illustrated by interactions between a hospital and a pharmaceutical manufacturer; how to transmit the intranet data to the extranet temporary storage module is described by taking an example of how the hospital a transmits the intranet data to the factory a. In this example, hospital a can only transmit a-type data for factory a, B-type data for factory B, and C-type data for factory C; therefore, the intranet temporary storage module corresponding to the hospital A is divided into a plurality of intranet temporary storage units, for example, the intranet temporary storage unit A, the intranet temporary storage unit B and the intranet temporary storage unit C. The intranet temporary storage unit A only stores the type A data (namely corresponding to the terminal of the plant A), the intranet temporary storage unit B only stores the type B data (namely corresponding to the terminal of the plant B), and the intranet temporary storage unit C only stores the type C data (namely corresponding to the terminal of the plant C). Meanwhile, the outer net temporary storage module corresponding to the plant A is the outer net temporary storage module A, the outer net temporary storage module corresponding to the plant B is the outer net temporary storage module B, and the outer net temporary storage module corresponding to the plant C is the outer net temporary storage module C. Therefore, in the specific data transmission, firstly, a target intranet temporary storage unit in the intranet temporary storage module is obtained, and the specific obtaining method includes that an intranet terminal selects a terminal connected with an extranet, specifically, for example, a terminal of a factory a, and the target intranet temporary storage unit is determined according to the terminal connected with the extranet, in this example, if the terminal connected with the extranet is the terminal of the factory a, the target intranet temporary storage unit is the intranet temporary storage unit a; or, the target temporary storage unit may be determined according to the received intranet data, specifically, for example, if the received intranet data is a type a data, the corresponding target temporary storage unit may be determined to be the intranet temporary storage unit a. After the intranet temporary storage unit A receives the intranet data, the intranet data is stored and whether a data transmission network is stable or not is monitored, if a network gate is in an open state, and the network state meets the data transmission requirement, the data stored in the intranet temporary storage unit A is transmitted to the extranet temporary storage module A.
Please refer to fig. 3, how to pull the data of the extranet in the temporary network storage module is taken as an example. And the outer net temporary storage modules corresponding to the plant A, the plant B and the plant C are respectively an outer net temporary storage module A, an outer net temporary storage module B and an outer net temporary storage module C. The intranet module A that keeps in that hospital A corresponds is divided into intranet unit A, intranet unit B and the intranet unit C that keeps in, and wherein, intranet unit A, intranet unit B and the intranet unit C that keeps in are used for saving extranet module A, extranet module B and the extranet data in the extranet module C that keeps in respectively. In the specific external data pulling process, firstly, pulling data in all external network temporary storage modules, namely pulling external network data in an external network temporary storage module A, an external network temporary storage module B and an external network temporary storage module C in the example; and then, the external network temporary storage module of the external network data source is matched with the corresponding internal network temporary storage unit to store the external network data. That is, if the extranet data comes from the extranet temporary storage module a, the extranet data is stored in the intranet temporary storage unit a; similarly, if the external network data comes from the external network temporary storage module B, the external network data is stored in the internal network temporary storage unit B; if the outer network data come from the outer network temporary storage module C, the outer network data are stored in the inner network temporary storage unit C.
For the situation that the external network temporary storage module is divided into a plurality of external network temporary storage units for pulling, please refer to fig. 4, where fig. 4 is a schematic diagram of a second terminal interaction provided in the embodiment of the present application, and the interaction between a hospital and a pharmaceutical manufacturer is still exemplarily explained; taking a plant A as an example, an outer net temporary storage module of the plant A is divided into an outer net temporary storage unit A, an outer net temporary storage unit B and an outer net temporary storage unit C, wherein the outer net temporary storage unit A, the outer net temporary storage unit B and the outer net temporary storage unit C respectively correspond to an inner net temporary storage module A (hospital A), an inner net temporary storage module B (hospital B) and an inner net temporary storage module C (hospital C); the intranet temporary storage module A can only pull the extranet data in the extranet temporary storage unit A, the intranet temporary storage module B can only pull the extranet data in the extranet temporary storage unit B, and the intranet temporary storage module B can only pull the extranet data in the extranet temporary storage unit B.
It should be noted that, can both divide into a plurality of intranet temporary storage units to intranet temporary storage module in practical application, divide into a plurality of outer net temporary storage units to outer net temporary storage module again to each intranet temporary storage unit of each intranet temporary storage module corresponds with each outer net temporary storage unit of each outer net temporary storage module, forms many-to-many's relation, after forming many-to-many's relation, its mode of drawing outer net data and sending intranet data is similar with the aforesaid, no longer gives details here.
In some optional embodiments, before sending the intranet data to the extranet temporary storage module and pulling the extranet data to the extranet temporary storage module, a compliance policy between an intranet-connected terminal and an extranet-connected terminal that receive the intranet data and pull the extranet data needs to be determined.
Specifically, taking a terminal connected to an intranet as a hospital and a terminal connected to an extranet as a pharmaceutical manufacturer as an example, the compliance policy refers to the type of data that can be interacted between the hospital and the pharmaceutical manufacturer, for example, the compliance policy specifies that the hospital can only send clinical data of a medicine to the pharmaceutical manufacturer, and only when the intranet data is the clinical data of the medicine, the intranet data can be sent to the extranet temporary storage module.
