Communication system and data transmission to transmit the mixed (complex) mode of transmission of the video data consists of a transmitting part are available on the mobile part of a mobile robotic system (Mrs), and the receiving part placed at the control point (CP).
The transmitting part contains a video camera (VC) 1, associated with matrix switchers (IAC) 2, the analog block encryption (BASH) 3, on-Board computer (BC) 4, the radio modem data (RMD) 5. BASH 3 is associated with the transmitter�ohms video (Purves) 6.

In the communication system and data transmission can be operated directional antennas receive and transmit (not shown) of the PU and the movable part MRK.
Way of organizing a wireless control channel of the mobile robotic complex is implemented as follows.
A control system for a mobile robotic system (Mrs) can be divided into two modules:
- Board computer system - a set of software and hardware that solves the problem of control of MRK and placed on the movable part of the chassis;
- operator console - a set of hardware and software tools placed on the machine control or on the remote.
The channel of communication between these modules should provide the following set of functions:
- send control commands and receive telemetry;
- the transmission of the image;
- transmission of service information, updating the firmware.
The evaluation and determination of necessary bandwidth (connection speed) channel for transmission of control commands and telemetry
Transmission of control commands priem telemetry is a sequence of byte oriented Protocol, asynchronously. Then the volume of one package is 100·8=800 bits. The dependence of the transmission from the speed shown in table 1.
|The dependence of the transmission time from the connection speed|
|Connection speed, bits/s||The packet transmission time, with||The amount of data, KB transferred in 1 minute|
Hence we can conclude that exceeds a connection speed above 19200 bps, no significant growth speed or performance of the information transferred over the communications channel.
Consequently, for satisfactory operation of the control system with proper organization of the exchange Protocol, primarily at the logical level there is no need to substantially increase the speed of the connection.
Assessment and determination of necessary bandwidth (connection speed) channel to transmit video
The video images are transmitted in digital form. Frame rate standard is 25 fps. a full-color Image. The resolution of the optical system of the camera is not worse than 520 TVL standard table control permissions.
The dependence of the volume information of the frame size (without compression) are shown in table 2.
|The dependence of the volume information of the frame size (uncompressed)|
|The frame resolution||The size of a single frame b||The data stream MB/s without compression|
|320 x 288 (QVGA)||309460||7,3|
|720×576 (D1)||1,27 MB||31,75|
|800×600 (SVGA)||1,47 MB||of 36.75|
|1024×768 (XGA)||2.3 MB||57,5|
|1280×720 (HD)||2.7 MB||67,5|
The dependence of the recognition of objects at a distance of 10 meters from the cameras of the frame size are shown in table 3.
|The dependence of the recognition of objects at a distance of 10 meters from the camera, from frame size|
|The frame resolution||Recognizability of large objects (truck side)||Recognizability of secondary objects (a human)||Recognition of small objects (cigarette pack)||Complex object (a man in camouflage)|
|176×144 (QCIF)||Good, identification depends on the skill of the operator||Satisfactory, difficult identification||Impossible||Impossible|
|320 x 288 (QVGA)||Good, identification depends on the skill of the operator||Good, identification depends on the skill of the operator||Satisfactory, difficult identification||Impossible|
|640×480 (VGA)||Excellent||Good, identification depends on the skill of the operator||Good||Impossible|
|800×600 (SVGA)||Excellent||Excellent||Excellent||Good, identification depends on the skill of the operator|
From table 3 it follows that the most appropriate is to set up the video cameras used on IRC, on the frame size 800×600 pixels, which provides image quality that is sufficient for most purposes.
The stage of the comparative analysis of compression formats and video, the choice of modes of the original image and the structure of subsystem of communication
Consider the most common formats of compression and transmission of video data.
Motion JPEG or M-JPEG digital video sequence consisting of a sequence of individual JPEG images. Display 16 or more frames per second is perceived visually as a video. Displaying to 30 (NTSC) or 25 (PAL) frames per second is perceived as full video.
One advantage of Motion JPEG is that each frame in the sequence is guaranteed quality is obtained on the compression level selected for camera or video encoder.
The lack of correlation between frames in Motion JPEG ha�antirust high reliability of this format, that is, the loss of one frame during transmission will not affect the quality of the rest of the video.
The MPEG-4 compliant MPEG-4 Part 2, MPEG-4 Visual.
MPEG-4 is used in applications requiring high image quality, virtually unlimited bandwidth and no restrictions on frame rate.
N. 264 or MPEG-4 Part 10/AVC
N. 264 or MPEG-4 Part 10/AVC is the modern standard for encoding video signals. As expected, the standard N. 264 will become in the coming years the most popular video standard. Coder N. 264 without compromising image quality may reduce the size of a digital video file by more than 80% compared to Motion JPEG format and 50% compared with MPEG-4 standard, which means much less demand on bandwidth for transmission and memory storage of the video file. Or, on the other hand, the possibility of obtaining a much better video quality at the same data rate.
Comparative analysis of compression formats are shown in table 4.
|Comparative analysis of compression formats|
|The type of compression format||The emergence of resistance to Arte�ctov traffic*||Resistance to breakages of transmission channel||The degree of compression, the volume of data flow (average)|
|Motion JPEG||Low, the emergence of the "squares" around moving objects||Relatively high, there is no delay when restoring channel, momentary loss of communication does not lead to loss or distortion of the image**||60% - 80% of the uncompressed|
|MPEG-4||Average, the appearance of "dropped out of lines"||Average recovery time image (0.5 to 2) after the restoration of the canal, a momentary loss of connection leads to distortion of the image||30% - 60% of the uncompressed|
|H. 264 or MPEG-4 Part 10/AVC||High, artifacts are missing||Low recovery time (2-10), intermittent loss of connection leads to loss of image||20% - 40% of the uncompressed|
|* - distortion in the image that appears when a fast moving object in the frame;
** - and�obrajenie freezes on steadily last accepted frame.
Thus, for video the most appropriate of the following modes of transmission of the original image: the frame size 800×600 pixels, compression MPEG-4. The data rate should be no worse than 10 Mbps.
Taking into account the above defined General block diagram of the communications subsystem.
The analysis phase characteristics of frequency bands and select the most appropriate for use in the MRC frequency range
To transmit video digital communication channel must have a high speed and noise immunity. Currently, the dominant technology is the transmission of digital data by Wi-Fi.
Regardless of the frequency of the WiFi in the device inoperable in the absence of direct visibility "receiver - transmitter" improving power output signal does not significantly increase the communication range.
In urban environments it is possible to establish due to random reflections of the signal from the designs of buildings and structures, but to ensure the stability of the channel is not possible.
Outside of the urban environment, on open plains, Wi-Fi devices work reliably, provided that the antennas are placed at a height exceeding the height of bushes and folds of the terrain.
Outside of the urban environment, in a wooded months�ness, WiFi devices unsuitable for reliable communication. According to various sources one meter crown attenuates the signal by 4 to 8 dB. The trees have a greater impact on the attenuation and scattering of the signal than the trunks. If necessary, ensure connection via WiFi, subject to the availability of individual trees it is advisable to mount the antenna below the tree canopy.
Comparative characteristics of the frequency bands given in table 5.
|Comparative characteristics of the frequency bands|
|Frequency range||The possibility of communication over long distances||The antenna length||The transmitter power|
|3-30 GHz||Theoretical - 200-500 km, the dispersion inhomogeneities in the troposphere*. Almost up to 500 m in line of sight||Within 10 cm||1 W|
|300 MHz - 3 GHz||Practical - 10 km||Within 4 meters||Up to 10 W|
|30-300 MHz||Practical - 50 km or more||Within 10 meters||Hundreds of watts or more|
|* - requires special design of antennas, the exact relative position of the receiving and transmitting antennas, complex signal processing.|
From table 5 it follows that the most suitable for use in the MRC is the range of decimeter waves. In this range remains acceptable transmitter power, and at the same time, when working in this range almost lost to the problem of communication in the city and open countryside, forests, at ranges up to (2-3) km.
The stage of formation of the structure of the communication system and data transmission based on the combined (integrated) method of transmitting information in digital and analog format
At the same time, it becomes impossible transmission of video signal in digital form, but a well-proven are the patterns of transmission of the video signal in analog form, and also there are radio modems for low-speed serial data transmission (mixed or integrated method of data transfer).
In the scheme of data transmission in a mixed way: VK 1 - sources of analog video format Composite Video or HS, MVK 2 - integrated chip that harmonize levels with�of galov VC 1, the formation of strong horizontal and vertical blanking and the input signals to the input of the BASH-3. The main objective of the ERM 2 - fetch the currently active VC 1 team BC 4 and the signal for further transmission. BASH 3 - provides protection of the signal from the decoding in intercepting radio. Protection is achieved by shifting the signal levels from the standard levels Composite Video and change the delays in the signals of the horizontal and vertical sweep. The Purves 6 transmits the encoded analog signal on the air.
In the scheme of reception of data in a mixed way: PRS 7 receives the encoded video signal, and transmitting the low frequency signal to the input of the BUD 8. BAD 8 restores the levels of the video signal to a standard Composite Video signal, regenerates the horizontal synchronization signals and vertical blanking, transmits a signal to the unit bus 10. Bus 10 converts the analog signal to digital for further processing and rendering on the CPU 9.
It follows from the foregoing that the most reliable radio channel is performed on the mixed scheme with analog video transmission and digital transmission of control commands and telemetry, operating in the range of decimeter waves.
The use of directional antennas receiving and transmitting from the control station and on the mobile part MRK
For higher�Oia reliability and stability of the communication channel may use directional antennas to be placed on the control point and the movable part MRK.
This technical solution allows to significantly improve the secrecy of the work of the MRC, and to provide a solution to the problem of navigation, because the antenna of the control point is the reference point and the known orientation of the bearing to the antenna of the control unit and the rotation angle of the transmitter antenna relative to the housing of the movable part MRK. In combination with the data odometry and Autonomous navigation systems these data are sufficient to solve the problem of localization systems MRK.
Thus, the proposed group of inventions solves the problem of achieving a technical result, which consists in creating a method of organizing wireless control channel of the mobile robotic complex and system communication and data transmission for the transmission of control commands and receiving telemetry, video image, the transmission of service information, upgrade firmware without increasing the complexity of the algorithm of functioning of communication systems and data transmission and use of technical means, while ensuring a high degree of reliability and stability of the communication channel.
