Description

FIELD OF TECHNOLOGY

The invention relates to the field of computing and instrumentation and can be used in multifunctional computing devices for video recording and video processing, in particular in on-board hardware video recording systems installed on public and commercial vehicles for the purposes of video monitoring and video recording.

BACKGROUND OF THE INVENTION

The onboard software and hardware system (UAH) is one of the types of automotive control system used mainly in ground public and commercial transport, operating continuously at the time specified by the operator, and providing fixation of specified events occurring throughout the entire operation time, in areas of interest in vehicle or outside. Recording of specified events can be performed using neural network models trained to detect specified events in a video stream. Such events can be, for example, the entry or exit of passengers, the tasks of tracking the occupancy of the cabin, counting the transported passengers, etc.

At its core, UAVs are video recorders with increased requirements that determine the tasks they solve. So, unlike the usual DVRs for personal use:

• The UAV is used to solve the problems of monitoring events occurring inside public and commercial transport, and not outside it, while several video cameras associated with the UAV are installed in the vehicle;

• In addition to video recording, the UAV performs the tasks of processing video stream data in order to process data and reduce the load on the data transmission channel, when only the result of processing is transmitted over the data transmission channels, which imposes requirements on the computing power of the UAV;

• The UAV must operate throughout the entire time the vehicle is on the line under any operating conditions, which implies the need to create conditions favorable for the long-term operation of the element base of the device.

These differences impose specific requirements on the hardware solutions used in the UAV.

From the utility model patent No. 170052, a special traffic accident video recorder is known, containing a processor, a memory unit, an overview video camera with software and hardware for determining video recording parameters, a GLONASS/GPS signal receiver, a G-sensor, a control unit, a visualization unit, a power, microphone, means for transmitting and receiving data, encrypting transmitted information and protecting all received data with an electronic digital signature. The processor of the DVR is equipped with a non-removable memory and is connected to the input and output of a wireless 3G / 4G modem, WiFi module, all DVR settings, viewing recorded events and changing software are carried out via the Internet. Data transfer is controlled by the patrol by pressing the "Violation" button (by pressing which the encrypted information is transferred to the traffic management center) or "Save" (to transfer information to the personal account).

This device can be selected as the closest analogue to the declared one. This device has several disadvantages.

Since the UAV performs video data processing tasks directly on the device, and video processing tasks, especially with the use of neural networks, are resource-intensive, if it is necessary to increase computing power with an increase in video data processing, it becomes impossible to do this without replacing the entire device. This shortcoming becomes especially noticeable with an increase in the number of video data sources (cameras).

In addition, the prototype does not provide climate control that allows you to maintain the required temperature for the functioning of the hardware of the device, which is important for the operation of the device in the northern regions. At the same time, electronic components that function stably at low temperatures have a significantly higher cost. Without the use of such an element base, situations arise when the device is unstable, malfunctioning, or does not work at all.

SUMMARY OF THE INVENTION

The objective of the invention is to develop an on-board hardware and software system with the possibility of increasing the computing power by replacing the computing device with a more productive one, with the possibility of maintaining the specified operating temperatures for the operation of the electronic components of the device.

A general diagram explaining the essence of the invention is shown in Fig. one

DETAILED DESCRIPTION OF THE INVENTION

In the following detailed description of the implementation of the invention, numerous implementation details are provided to provide a clear understanding of the present invention. However, one skilled in the art will appreciate how the present invention can be used, both with and without these implementation details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to unduly obscure the features of the present invention.

Moreover, it will be clear from the foregoing that the invention is not limited to the present implementation. Numerous possible modifications, changes, variations and substitutions that retain the spirit and form of the present invention will be apparent to those skilled in the subject area.

The present invention is directed to the implementation of an onboard hardware-software complex with the possibility of increasing the computing power, with the possibility of maintaining the specified operating temperatures for the operation of the electronic components of the device.

As shown in FIG. 1.2, the claimed UAV (100) includes interconnected elements, namely an expansion board (101), a computing device (102), at least one video camera (103).

The expansion board (101) is a printed circuit board with electronic components located on it, ensuring the operation of the following blocks:

• GNSS signal receiver (1011) - is a global positioning device based on global navigation satellite systems, used to determine the location at any point on the earth's surface using constellation signals (GPS, Glonass, Doris, Beidou, Galileo, etc.).

• Accelerometer (1012) - a device that allows you to determine the acceleration, which is necessary for the operation of software solutions embedded in the functionality of the UAV, in particular, to determine the periods of stopping the vehicle without the need to connect to the CAN bus of the vehicle.

• Means of transmitting and receiving data (1013) - a device that enables wireless data transmission via GSM mobile communication networks.

• Temperature control device (1014) - a device that maintains a predetermined temperature regime inside the UAV case in order to create optimal temperature conditions for the operation of electronic components.

The computing device (102) is a microcomputer with a UART interface that can perform video data processing tasks using processing software (1021), in particular software for calculating incoming / outgoing passenger traffic to control the number of passengers transported and the load on the vehicle.

At least one video camera (103) is connected to the computing device (102), preferably using a wired connection, for example, via a USB interface, but other types of connections that the computing device (102) supports can also be used, including wireless connection interfaces.

The UAV (100) operates in a continuous mode, providing the logic for processing the video data stream embedded in the computing device (102), including using neural networks, using service information from the modules of the expansion board (101). Thus, the UAV (100) in the process of operation binds the video stream to the coordinates of the vehicle at the current time using the GNSS signal receiver module (1011), the accelerometer (1012) activates the launch of the software necessary to calculate the incoming / outgoing passenger traffic at the moments of the vehicle stopping , which allows you to get numerical analytics along the entire route of the vehicle and transfer it using the means of receiving and transmitting data (1013). The temperature control device (1014) maintains the optimal operating temperature inside the BPAC case (100), ensuring stable long-term trouble-free operation of the electronic components of the complex in a wide temperature range, which is important at an outside air temperature of less than 0°C. This solution allows you to significantly expand the possibility of increasing computing power, since many computers with high performance are demanding on operating conditions.

The computing device (102) and the expansion board (101) are connected through a universal asynchronous transceiver (UART), also known as the Universal Asynchronous Receiver-Transmitter (UART) - a node of computing devices designed to organize communication with other digital devices, which converts the transmitted data into serial view so that it is possible to transfer them over one physical digital line to another similar device. The widespread use of UART in digital technology predetermined the embedding of support for this standard in almost all personal computers and operating systems. As a rule, this interface appears in the OS documentation as a COM port or a serial port. Such a communication implementation makes it possible to replace the computing device (102) with a more productive one while maintaining the modules (1011), (1012), (1013), (1014) regardless of the computing device used. Replacement of the computing device (102) is carried out by disconnecting the wired interfaces, mechanically disconnecting it from the case, the connection is carried out in the reverse order.

Architectural software processing tools (1021) are software solutions (programs) that allow you to process a video stream for further processing in the UAV (100) or for transmission using transmission reception tools. For example, the processing software (1021) may include decoders that allow you to compress the video stream to reduce the load on data channels; semantic video segmentation programs for classifying elements in a picture for subsequent analytics tasks (such as, for example, counting passenger traffic). Processing software (1021) is performed with the possibility of updating them to expand the functionality of the complex.

On FIG. 4 below will be presented the general scheme of the computing device (102), which provides the data processing necessary for the implementation of the claimed UAV (100).

In general, the device (102) contains such components as: one or more processors (1021), at least one memory (1022), data storage device (1023), input/output interfaces (1024), input/output devices ( 1025). Depending on the computing device used, it may also contain other elements that do not limit the functionality of the described solution.

The processor (1021) of the device performs the basic computational operations necessary for the operation of the device (102) and the BPA (100). The processor (1021) executes the necessary machine-readable instructions contained in the main memory (1022).

The memory (1022), as a rule, is made in the form of RAM and contains the necessary software logic that provides the required functionality.

The data storage device (1023) can be in the form of HDD, SSD disks, RAID array, network storage, flash memory, optical information storage devices (CD, DVD, MD, Blue-Ray disks), etc. The device (1023) allows long-term storage of various types of information, such as video stream, data processing history (logs), digital images, analytical data, coordinates, etc.

Interfaces (1024) are standard means for connecting and working with a device (102), such as USB, RS232, RJ45, LPT, COM, HDMI, PS/2, Lightning, FireWire, etc. The choice of interfaces (1024) depends on the specific version of the device (102).

The following input/output means (1025) can be used: keyboard, joystick, display (touch screen), projector, touchpad, mouse, trackball, light pen, speakers, microphone, etc., which are used during the device setup steps and obtain the necessary data from it.

The components of the device (102) are coupled via a common data bus (1020).

An example of an actual implementation of the AUTO (100) is shown in FIG. 3.

In these application materials, a preferred disclosure of the implementation of the claimed technical solution was presented, which should not be used as limiting other, private embodiments of its implementation, which do not go beyond the requested scope of legal protection and are obvious to specialists in the relevant field of technology.
