Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all 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.
With the development of science and technology and the progress of technology, network security is more and more emphasized. The security processing measures that the network cannot directly interconnect and interwork become a conventional means for security assurance between networks with different functions or different security level requirements, which is called physical network isolation. Physical network isolation as used herein means that the networks do not communicate with each other, but the devices exist in the same room space. In some specific scenarios, data information to be transmitted exists between physical isolation networks, and in the past practice, data ferry technologies such as optical disc/media ferry are adopted, but with the improvement of the informatization degree and the improvement of the data transmission speed, the timeliness of the optical disc/media ferry cannot meet the requirements of actual needs, so that various graphic code ferry technologies come into play.
At present, the main ways of data transmission between physically isolated networks are: by adopting a graphic code ferrying technology, a data sending end generates a two-dimensional code for sending data, a receiving end receives the data according to the two-dimensional code, in the process, the data sending end refreshes the two-dimensional code of the data according to a corresponding time interval, and the receiving end snapshotts the two-dimensional code of the data according to the corresponding time interval. Therefore, there is a problem that data transmission synchronization is inaccurate.
Therefore, the present application provides a synchronization method and apparatus for data transmission, in which a near field communication manner is adopted, a sending end notifies a receiving end of data transmission, and after the receiving end receives the data, the receiving end notifies the sending end that the data reception is completed, thereby completing a complete data transmission. By means of the mode, the data transmission can be more accurately synchronized. In the data transmission process, overtime processing is added, and once transmission is overtime, early warning is carried out, so that safe and stable operation of data transmission is guaranteed.
Fig. 1 is a synchronization scenario diagram of data transmission according to an embodiment of the present application, as shown in fig. 1, including: the communication system comprises a sending end 110, a first communication device 120, a second communication device 130 and a receiving end 140, wherein the first communication device 120 and the second communication device 130 communicate in a near field communication mode. The networks between the sender 110 and the receiver 140 do not interwork. The sending end 110 generates a corresponding two-dimensional code from the data to be sent to the receiving end 140, and displays the two-dimensional code on the display 111 of the sending end. The receiving end 140 captures the two-dimensional code of the data to be transmitted displayed on the display 111 of the transmitting end through the shooting device 141, analyzes the two-dimensional code to obtain the data transmitted from the transmitting end 110 to the receiving end 140, completes the process of transmitting the data from the transmitting end 110 to the receiving end 140 once, and then the transmitting end 110 and the receiving end 140 start to transmit the next data. When the sending end 110 and the receiving end 140 perform data transmission, synchronization of data transmission is completed according to communication between the first communication device 120 and the second communication device 130, and specific implementation processes may refer to schemes of the following embodiments.
Fig. 2 is a flowchart of a synchronization method for data transmission according to an embodiment of the present application, and as shown in fig. 2, the method of the embodiment may include:
s201, when the first communication device determines that the current data sent to the receiving end by the sending end through the physical isolation network is ready, the first communication device sends first information to the second communication device in a near field communication mode. Correspondingly, the second communication device receives the first information sent by the first communication device in a near field communication mode. The first information is used for indicating that the current data sent to the receiving end by the sending end through the physical isolation network is ready to be finished.
In this embodiment, specifically, the physical isolation network is a network in which the sending end and the receiving end are not intercommunicated, and accordingly, the sending end sends the current data to the receiving end through the physical isolation network, for example, the sending end sends the current data to the receiving end in a manner of generating a two-dimensional code of the current data and displaying the two-dimensional code, and the receiving end receives the data by capturing the two-dimensional code of the current data displayed by the sending end. The method comprises the steps that a near field communication mode is determined in advance between first communication equipment and second communication equipment, after the first communication equipment receives request information of the completion of the preparation of current data of a sending end, the first communication equipment determines that the preparation of the current data sent to a receiving end by the sending end through a physical isolation network is completed, the first communication equipment sends first information to the second communication equipment in the near field communication mode, and the feedback information of the request information corresponding to the data receiving is recorded. Specifically, the first information is used to indicate that the current data sent by the sending end to the receiving end through the physical isolation network is ready.
Correspondingly, the second communication device receives first information sent by the first communication device in a near field communication mode, wherein the first information is used for indicating that the current data sent to the receiving end by the sending end through the physical isolation network is ready.
Optionally, the second communication device receives the first information sent by the first communication device within a third preset time period by using a near field communication method.
In this embodiment, a third preset duration period has been preset, and the third preset duration period is, for example: and 10 seconds, the configuration can be carried out according to different service requirements and the size of the data block, and the minimum time can not be less than 1 second. Therefore, the second communication device receives the first information sent by the first communication device within a third preset time period by adopting a near field communication mode.
Optionally, the short-range communication mode includes an infrared communication mode or an optical communication mode.
In this embodiment, the short-range communication method may be an infrared communication method or an optical communication method. For example: the near field communication mode is an infrared communication mode, and the first communication device and the second communication device are both provided with infrared sensors. When the first communication equipment determines that the current data sent to the receiving end by the sending end through the physical isolation network is ready, the information of the current data ready is transmitted to the infrared sensor of the first communication equipment through the common COM communication protocol, the infrared sensor of the first communication equipment sends the first information to the second communication equipment in a mode of sending infrared rays outwards, and meanwhile, a reverse receiving device of the infrared rays is started to wait for a data transmission completion signal. Correspondingly, the infrared sensor of the second communication device is always in a state of waiting for receiving information, receives the first information sent by the first communication device, and simultaneously sets the function of finishing signal transmission to be in a waiting state to wait for receiving the information of finishing data transmission.
S202, the second communication device sends the second information to the receiving end, and correspondingly, the receiving end receives the second information sent by the second communication device. The second information indicates that the receiving end receives the current data sent by the sending end through the physical isolation network.
In this embodiment, the second communication device has already received the first information sent by the first communication device in the near field communication manner, and therefore, the second communication device sends the second information to the receiving end while waiting for the feedback result of the receiving end. Specifically, the second information indicates that the receiving end receives the current data sent by the sending end through the physical isolation network, for example: and the sending end generates the two-dimensional code of the current data and displays the two-dimensional code, and the second information indicates the receiving end to receive the current data sent by the sending end by capturing the two-dimensional code of the current data displayed by the sending end. Accordingly, the receiving end receives the second information sent by the second communication device.
And S203, when the second communication device determines that the receiving end has finished receiving the current data through the physical isolation network, the second communication device sends third information to the first communication device in a near field communication mode. Correspondingly, the first communication device receives the third information sent by the second communication device in a near field communication mode. The third information is used for indicating that the receiving end has finished receiving the current data.
In this embodiment, the near field communication method is, for example, an infrared communication method, and the first communication device and the second communication device are both provided with an infrared sensor. After the second communication device receives the request information that the current data of the receiving end is received, when the receiving end is determined to complete the receiving of the current data through the physical isolation network, the information that the current data is received is transmitted to the infrared sensor of the second communication device through the general COM communication protocol, and the infrared sensor of the second communication device sends third information to the first communication device in a mode of sending infrared rays outwards. Specifically, the third information is used to indicate that the receiving end has completed current data reception through the physical isolation network.
Accordingly, the infrared sensor of the first communication device receives the infrared signal transmitted by the infrared sensor of the second communication device to receive the third information. Specifically, the third information is used to indicate that the receiving end has completed the current data reception.
Optionally, the first communication device receives, in a second preset time period, third information sent by the second communication device in a near field communication manner.
In this embodiment, if a time period from when the sending end sends data to when the receiving end sends a data receiving result is set as a sending duration period, and a time period from when the receiving end sends a data receiving result to when the sending end sends a data receiving result is set as a receiving duration period, the second preset duration period takes a floating height of 50% of a total of the sending duration period and the receiving duration period as a threshold, for example: the sending duration period is 30 seconds, the receiving duration period is 30 seconds, and the second preset duration period is 90 seconds. Therefore, the first communication device receives the third information sent by the second communication device within a second preset time period by adopting a near field communication mode.
And S204, the first communication equipment sends fourth information to the sending end. Accordingly, the transmitting end receives the fourth information transmitted by the first communication device. The fourth information is used to indicate that the receiving end has completed receiving the current data, so that the transmitting end starts to prepare for transmitting the next data.
In this embodiment, the first communication device has already received the third information sent by the second communication device in the near field communication method, and therefore the first communication device sends the fourth information to the sending end. Specifically, the fourth information is used to indicate that the receiving end has completed receiving the current data, so that the transmitting end starts to prepare for transmitting the next data. Accordingly, the transmitting end receives the fourth information transmitted by the first communication device.
On the basis of the above embodiment, the sending number and the receiving number of each communication device in a period of time can be counted according to the log information of the first communication device and the second communication device, and when the sending and receiving numbers are inconsistent, an early warning can be given in a mode of a mobile phone short message, for example.
In the synchronization method for data transmission provided in this embodiment, when it is determined that the current data sent by the sending end to the receiving end through the physical isolation network is ready to be sent by the first communication device, the method comprises the steps of sending first information to a second communication device by adopting a near field communication mode, receiving the first information sent by a first communication device by the second communication device by adopting the near field communication mode, sending second information to a receiving end by the second communication device, when the second communication device determines that the receiving end finishes receiving current data through a physical isolation network, and the first communication device transmits fourth information to the transmitting end, wherein the fourth information is used for indicating that the receiving end finishes receiving the current data so as to enable the transmitting end to start to prepare for transmitting the next data. According to the method and the device, when the sending end and the receiving end transmit data through the physical isolation network, the data transmission synchronization is ensured through the close-range communication mode between the first communication equipment and the second communication equipment, and therefore the data transmission synchronization can be accurately carried out.
On the basis of the embodiment shown in fig. 2, optionally, before performing S201, the method further includes S200:
s200, the first communication device receives fifth information sent by the sending end in a first preset time period, wherein the fifth information is used for indicating that the current data sent to the receiving end by the sending end through the physical isolation network is ready.
In this embodiment, the sending end sends the fifth information to the first communication device after the current data preparation is completed. The first communication device has preset a first preset duration period, for example: 2 seconds, the configuration can be performed according to different service requirements and the size of the data block, and the minimum time cannot be less than 1 second. The first communication device receives the fifth information sent from the sending end by adopting a passive interface mode (socket, restul, SOAP, etc.). The interface mode is for example: in the socket mode, a standard socket protocol is adopted, the first communication equipment serves as a socket server to provide request service for the sending end, and the sending end can complete the request service only by knowing an IP (Internet protocol) and a port; in the RESTFUL mode, an HTTP protocol is adopted, the first communication equipment exposes a network request address outwards, a sending end only needs to request according to the network address mode, and the data format can adopt a json format; the SOAP mode is basically the same as the restul mode, except that the data format adopts the XML format of SOAP. Therefore, the first communication device receives fifth information sent by the sending end within a first preset time period, where the fifth information is used to indicate that preparation of current data sent by the sending end to the receiving end through the physical isolation network is completed.
Optionally, the first communication device determines, according to the fifth information, that preparation of current data sent by the sending end to the receiving end through the physical isolation network is completed.
In this embodiment, the first communication device receives the fifth information sent by the sending end, and therefore, according to the fifth information, the first communication device determines that preparation of current data sent by the sending end to the receiving end through the physical isolation network is completed.
Optionally, before executing S203 and after S202, the method further includes S205:
and S205, the second communication device receives sixth information sent by the receiving terminal in a fourth preset time period, wherein the sixth information is used for indicating that the receiving terminal has finished receiving the current data through the physical isolation network.
In this embodiment, after the receiving end receives the current data, the receiving end sends sixth information to the second communication device. The second communication device has preset a fourth preset duration period, for example: 2 seconds, the configuration can be performed according to different service requirements and the size of the data block, and the minimum time cannot be less than 1 second. Specifically, the second communication device receives request information that the current data from the receiving end has been received in a passive interface manner (socket, restul, SOAP, or the like). Therefore, the second communication device receives, within a fourth preset duration period, sixth information sent by the receiving end, where the sixth information is used to indicate that the receiving end has completed receiving the current data through the physical isolation network.
Optionally, the second communication device determines that the receiving end has completed receiving the current data through the physical isolation network according to the sixth information.
In this embodiment, the second communication device receives the sixth information sent by the receiving end, and therefore, according to the sixth information, the second communication device determines that the receiving end has completed receiving the current data through the physical isolation network.
Optionally, if the first communication device does not receive the fifth information sent by the sending end within the first preset time period, the first warning information is output.
