Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to a method and device for converting heterogeneous information. Background Art

[0002] The UAV ground control vehicle mainly completes the command and control of the UAV, including the monitoring of the link, the control of the flight platform and the payload platform, mission planning, information processing and distribution, etc. In order to complete these functions, many devices need to be loaded in the ground control vehicle. These devices usually use different interface types. The mission information data uses the synchronous 422 serial port, the meteorological equipment and the positioning and orientation equipment use the asynchronous 232 serial port, the remote control and telemetry data use the asynchronous 422 serial port, and the video data uses the PAL video interface. The comprehensive processing software of the host computer uniformly uses the Ethernet interface. The communication protocols of these interface signals are different, and data communication cannot be carried out between the devices, which has an impact on the expansion of the ground control vehicle system or information compatibility. The patent with application number 201010103598.8 proposes a multifunctional interface conversion device that converts USB interface, asynchronous 232 serial port, asynchronous 422 serial port, RS485 serial port and CAN bus interface into Ethernet interface data. It contains a human-computer interaction module, which needs to be set by the user. The central processing unit performs corresponding parameter settings and interface switching according to the working mode set by the user. Patent application number 201820238579.9 proposes a multifunctional communication interface converter, which realizes the conversion between various communication interfaces such as asynchronous 232, RS485 serial interface, CAN bus interface, optical fiber interface, and Ethernet interface through a mature and reliable communication interface board. Both inventions cannot realize the mutual conversion between synchronous 422 serial port and PAL video and Ethernet, and the former invention needs to be set up before each use, which adds unnecessary operation steps, while the latter invention only involves the conversion of the underlying hardware.

[0013] Example 1 According to an embodiment of the present invention, a method for heterogeneous information conversion is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system containing at least one set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0014] Figure 1 is a flow chart of a heterogeneous information conversion method according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps: Step S101: if there is a host computer and several devices in the UAV ground control vehicle, and each device has a different interface type, and the host computer and each device interface type are different, initialize each device interface and the host computer interface.

[0015] In the technical solution provided in the above step S101 of the present invention, when there are a host computer and several devices in the UAV ground control vehicle, the interface of the host computer is different from the interface type of each device, and the interface type of each device is different from that of each device. Initialize each device interface: after the serial port number is configured, perform the serial port opening operation. If the serial port is opened normally, set the baud rate and initialize the host computer interface: configure the local address, local port number, multicast address, and multicast port number.

[0016] Step S102, when uploading the data of each device to the host computer and sending the host computer data to each device, simultaneously detect whether there is any data update in the receiving buffer area of ​​each device and the host computer interface. When there is data update, the data in the receiving buffer area of ​​each device interface is processed and placed in the network sending buffer area and sent to the host computer; the data in the receiving buffer area of ​​the host computer interface is processed and placed in the data buffer area of ​​each device interface and sent to each device.

[0017] In the technical solution provided in the above step S102 of the present invention, when the data of each device is uploaded to the host computer and the host computer data is sent to each device, it is simultaneously detected whether there is any data update in the receiving buffer area of ​​each device interface and whether there is any data update in the receiving buffer area of ​​the host computer interface. If there is data update in the receiving buffer area of ​​each device interface and the host computer interface, the data in the receiving buffer area of ​​each device interface is processed and placed in the network sending buffer area and sent to the host computer; the data in the receiving buffer area of ​​the host computer interface is processed and placed in the data buffer area of ​​each device interface and sent to each device.

[0018] The above method of this embodiment is further introduced below.

[0019] As an optional implementation manner, in step S101, each device interface is an asynchronous RS232 serial port, an asynchronous RS422 serial port, a synchronous 422 serial port or a PAL video interface, and the host computer interface is an Ethernet interface.

[0020] As an optional implementation method, step S102, the data in the receiving buffer area of ​​each device interface is processed and placed into the network sending buffer area and sent to the host computer, including: when the interface of the device is an asynchronous RS232 serial port, an asynchronous RS422 serial port or a synchronous 422 serial port, the data in the receiving buffer area of ​​the device interface is packaged and encoded and converted into network data of the data type corresponding to the asynchronous RS232 serial port, the asynchronous RS422 serial port or the synchronous 422 serial port, placed into the network sending buffer area and sent to the host computer; when the interface of the device is a PAL video interface, the PAL video data is converted into HD video data and stored in the video data buffer area, an interrupt signal is generated, the HD video data is compressed and encoded, and converted into network data of the data type corresponding to the PAL video interface, placed into the network sending buffer area and sent to the host computer.

[0021] In this embodiment, Figure 2 1 is a flowchart of the heterogeneous data to network data conversion process according to an embodiment of the present invention. Figure 2 As shown, whether there is data update in the asynchronous RS232 serial port receiving buffer area, if there is data update, the data is unpacked and encoded according to the specified protocol, and converted into network data in a specified format, and it is placed in the network sending buffer area and sent.

[0022] The steps of converting asynchronous RS422 serial port data to network data and the steps of converting synchronous 422 serial port data to network data are the same as the steps of converting asynchronous RS232 serial port data to network data.

[0023] In the step of converting analog video data to network data, when analog video PAL data is input, the PAL video data is converted into 16-bit HD raw video data through the video decoder TVP5158, stored in the video data buffer, and an interrupt signal is generated and sent to the video processor DM8158 for video compression and encoding, and converted into network data in a specified format, placed in the network data sending buffer and sent.

[0024] For example, to convert synchronous 422 serial port data to network data: The first step is to initialize the parameters; The second step is to simultaneously detect whether the receiving buffer area of ​​each device and the host computer interface has data updated; Step 3: When it is detected that there is serial port data update in the synchronous 422 serial port data buffer, the data is packaged every 512 bytes according to the following network protocol format, where 0-3 bytes are the frame header, 4-7 bytes are the frame length, 8-9 bytes are the frame sequence number, 10 bytes are spare, 11 bytes are the data source number, 12-13 bytes are spare, 14-525 bytes are frame data, and 526-527 are the frame tail; The fourth step is to put the packaged data into the network data sending buffer, send it to the pre-set network address and port, and clear the sending buffer at the same time.

[0025] As an optional implementation method, step S102, the data in the receiving cache area of ​​the host computer interface is processed and placed into the data cache area of ​​each device interface and sent to each device, including: judging the data type of the receiving cache area of ​​the host computer interface based on the characteristics of the data in the receiving cache area of ​​the host computer interface, wherein the data type of the receiving cache area of ​​the host computer interface includes asynchronous RS232 serial port data, asynchronous RS422 serial port data, synchronous 422 serial port data and PAL video interface data; based on the data type of the receiving cache area of ​​the host computer interface, converting the data in the receiving cache area of ​​the host computer interface into data of a corresponding type; placing the converted data in the receiving cache area of ​​the host computer interface into the data cache area of ​​the corresponding device interface and sending it to the corresponding device.

[0026] In this embodiment, Figure 3 1 is a flowchart of the network data conversion process according to an embodiment of the present invention. Figure 3 As shown, the type of data in the receive buffer area of ​​the host computer interface is determined based on the characteristics of the data in the receive buffer area of ​​the host computer interface; the data in the receive buffer area of ​​the host computer interface is converted into data of a corresponding type according to the type of data in the receive buffer area of ​​the host computer interface; the converted data in the receive buffer area of ​​the host computer interface is placed into the data buffer area of ​​the corresponding device interface and sent to the corresponding device.

[0027] As an optional implementation method, the data type of the receiving cache area of ​​the host computer interface is converted into data of a corresponding type based on the data type of the receiving cache area of ​​the host computer interface, including: when the data type of the receiving cache area of ​​the host computer interface is an asynchronous RS232 serial port, asynchronous RS422 serial port or synchronous 422 serial port data type, the data in the receiving cache area of ​​the host computer interface is encoded and framed to obtain corresponding asynchronous RS232 serial port data, asynchronous RS422 serial port data or synchronous 422 serial port data; when the data type of the receiving cache area of ​​the host computer interface is a PAL video interface data type, the data in the receiving cache area of ​​the host computer interface is converted into HD video data and sent to the video data cache area; when the video data cache area has data update, the HD video data is converted into PAL analog video data.

[0028] In this embodiment, in the step of converting network data to heterogeneous data, it is detected whether there is data update at the Ethernet receiving buffer area. If there is data update, it is judged according to the network address and port, and the data is classified. If it needs to be converted into an RS232 serial port data type, it is encoded and framed according to the specified format, placed in the RS232 serial port data sending buffer area, and sent; if it needs to be converted into an RS422 serial port data type, it is encoded and framed according to the specified format, placed in the RS422 serial port data sending buffer area, and sent; if it needs to be converted into a synchronous 422 serial port data type, it is encoded and framed according to the specified format, placed in the RS422 serial port data sending buffer area, and sent; if it needs to be converted into a PAL analog video data type, the network data is sent to the video processor DM8158 for decompression processing to obtain the original video data, and the original video data is stored in the video data buffer area. When it is detected that there is data update in the video data buffer area, it is sent to the video decoder TVP5158 to convert the original video data into PAL analog video data of the specified format, put it into the video data sending buffer area, and send it.

If the serial port is opened normally, set the baud rate and initialize the host computer interface: configure the local address, local port number, multicast address and multicast port number.
