B61K 9/02, 2006).

The disadvantage of this device is that the installation of optical cameras does not provide a clear view of the side walls of the car, because side chambers are placed at the upper level of the side walls and are directed horizontally to the car. In addition, installing a third camera above the wagon will not allow the operator to focus on three different images on a video monitoring device.

The closest in technical essence and the achieved result is an automated system for commercial inspection of trains and wagons, containing an optoelectronic sensor of the beginning of the train and mounted above the rail by a U-shaped load-bearing structure, on which a television camera designed to obtain images of the roof of wagons, five optoelectronic control sensors are placed dimensions of loading cars, an optoelectronic sensor for counting cars, while the outputs of the sensors are connected to the inputs of the display unit and according to An alarm, the output of the indication and matching unit is connected to the input of a personal electronic computer (PC) of the operator’s workstation, to the output of which a monitor is connected, four additional optoelectronic sensors for monitoring the overall loading of cars, an optoelectronic wheel pair counting sensor, three additional television cameras designed to obtain images of the left and right sides of cars, as well as control seals of tank hatches, and searchlights, with the additional Numerous sensors for monitoring the loading dimensions of cars are mounted on a supporting structure with the possibility of monitoring together with other similar sensors of the boundaries of the combined zonal loading and vehicle dimensions, an optoelectronic sensor for the beginning of the train, an optoelectronic sensor for counting wheelsets, television cameras on the left and right sides of the cars are fixed on supports, the television camera for monitoring the seals of tank hatches is on the crossbar, and the spotlights are on the supports and the crossbar of the supporting structure, the outputs of all television the amer is connected to the PC video inputs, the outputs of the additional sensors for monitoring the loading dimensions of the cars and the wheel pair counting sensor are connected to the corresponding inputs of the indicating and matching unit connected by the control input to the output of the personal computer, the indicating and matching unit is capable of working offline (RU 2252170, cl . B61K 9/02, 2004).

The disadvantage of this device is the difficulty of the operator observing the images of moving cars on four optical cameras. In this case, the operator does not have time to visually assess the condition of an individual car from fragmentary images of its parts.

The technical result of the invention is to simplify the design and improve the quality of inspection of wagons due to the installation of two optical cameras on the sides with image capture of a separate wagon.

The specified technical result is achieved by the fact that in the device for commercial control of wagons containing optical cameras mounted on poles connected to the input of a video monitoring computer device, the optical cameras are mounted symmetrically with respect to the axis of the railway track from the sides above the controlled wagons and are equipped with electric drives to change the installation angle to permitted loading and selection of shooting mode, each of the optical cameras is connected to a computer input, with a memory unit connected to it and at the same time, track sensors are installed in the control zone on the rails, the distance between which is equal to the length of the car, the outputs of the sensors are connected to the inputs of the computer, the output of which through the interface unit is connected to the control inputs of the optical drives of the optical cameras.

As optical cameras use digital cameras. The essence of the proposed device is illustrated by drawings, where figure 1 shows the cross section of the car and the installation of optical cameras; figure 2 - installation diagram of the optical camera for inspection of the car from the left side; figure 3 is the same on the right side; figure 4 is a side view of the device; figure 5 is a top view; figure 6 - frame size on the left side; 7 is a frame size on the right side; Fig. 8 is a control block diagram of the device; and Fig. 9 is a connection of an optical camera in the form of a digital camera to a video monitoring device.

A device for commercial control of wagons comprises optical cameras 2 mounted on supports 1 and connected to the input of a computer video control device 3. Optical cameras 2 are mounted symmetrically with respect to the axis of the railway track 5 from the sides above the controlled wagons 6. Track sensors 7 and 8 are installed in the control zone The optical cameras 2 are equipped with electric drives 9-11 for changing the installation angle to the permitted loading dimension and selecting a shooting mode. Each of the optical cameras 2 is connected to the input of the computer 4 with a connected memory unit 12. The track sensors 7 and 8 are mounted on the rails 13 at a distance equal to the length of the car 5, and are connected to the inputs of the computer 4. The output of the computer 4 through the interface unit 14 is connected with the control inputs of the electric drives 9-11 optical cameras 2. As optical cameras 2 use digital cameras 15.

Each camera 15 is connected by one cable to the computer 4 with the ability to control the modes "Photography" and "Video" and another cable to the input of the video control device 3. The computer 4 is connected to the server 17 of the automated control system (ACS) of the business infrastructure.

Block 14 interface is designed to coordinate the output of the computer 4 with the control inputs of the electric drives 9-11. The electric drive 9, designed to rotate the cameras 15 in a vertical plane, is made in the form of a rack and pinion mechanism. As the electric drive 10, a servo drive in the form of a translational on-off action mechanism is used. As the drive 11, a servo drive from a rotational cyclic mechanism is used.

The camera 15 is mounted on a support 1 by installing it in a tripod socket 18 with the possibility of an adjustable view in the transverse vertical plane using an electric drive 9. From above, the camera 15 is covered with a protective casing 19. The attachment points 20 are fixed in the position of the best sharp image of the car 6.

Each camera 15 is mounted on a support 1 with the possibility of obtaining a viewing area from one side wall with a roof to both borders of the end walls of the examined car 6 (Fig. 5) between the track sensors 7 and 8.

The device operates as follows.

Two optical cameras 2 on the supports 1 are included in the work only after their installation with the coverage of the entire car 6 to the permitted loading dimension. The optical axis of each optical camera 2, made in the form of a camera 15, is directed from one and the other sides respectively perpendicular to the line of intersection of the extreme point of the lower dimension (CT _NG ) of the floor of the near side wall of the wagon 6 and the extreme point of the upper dimension (CT of the _VG ) of the far side wall wagon 6. Moreover, each camera 15 is installed with the possibility of obtaining a field of view of the wagon 6 to its both borders of the end walls when the wagon 6 is in the control zone between the two track sensors 7 and 8. The latter are installed vayut on a railway line at a distance equal to the length of the carriage 6, for example, in its coupler. Figure 4 shows the installation of sensors 7 and 8 under the extreme wheels of the car 6. The length of the car 6 can be determined in this way.

The camera mode 15 "Photography" is selected with the possibility of inclusion in the photographing of the electric drive 10 from two track sensors 7 and 8 while placing a controlled car 6 between them. The “Video Recording” mode is selected by the electric drive 11 and turned on by the same electric drive 10 when the wheels contact one of the track sensors, for example 7.

The “Photography” mode can be set with the following time interval:

where L is the length of one car according to automatic couplings, m;

V is the speed of movement of the composition of the cars, m / s.

When working from the wheels of cars 6 pedals of track sensors 7 and 8, for example type PBM-56. If the calculation is taken for the length of the car 6 its base, i.e. the distance between the first wheels of the different wagon trolleys, which is equal to the distance between the wagon trolleys, then in this case the control zone narrows. In it, the “running” and past end walls of the car 6 will be visible only at the edges of the frame.

The “Video Recording” mode includes a complete recording of images of the entire composition of the cars when they are briefly in the control zone between two track sensors 7 and 8.

At the time of control, the composition of the cars passes under vertically mounted supports 1 with optical cameras 2 placed on its two sides. Optical camera 2, for simplicity, can be made in the form of a widely used digital camera 15, for example, Sony. The obtained photos and images of this camera can be viewed on the screen of the video monitoring device 3. If it is impossible to connect two cameras 15 to one video monitoring device 3 of a computer 4 or receiving two images on it, the second video monitoring device is placed on the AWP of the train receiver 3. Camera operation 15 “Mode” , "Start", "Saving files", etc. is carried out automatically according to the program with a computer 4.

Thus, photographing wagons 6 is carried out depending on the need in two modes "Photography" and Video ".

The inclusion, operation and shutdown of each camera 15 is performed according to a given program by the operator-receiver of the train of buttons on the computer keyboard 4.

The “Photography” mode can be activated when the first carriage 6 reaches the border of the control zone, in which the walls and roof of carriage 6 are inspected. Then this is done with the second carriage and so on until the last carriage. At the end of the work, a file is recorded with the captured frames in the computer for subsequent monitoring and evaluation of the technical condition of the car 6 and the safety of the cargo in it.

The "Photography" mode is carried out when controlling each car 6 individually. The operator looking at the screen of the video control device 3 and seeing that the carriage 6 completely falls into the lens overview of one of the cameras 15, presses one of the keys of the computer keyboard 4, which remotely controls the start button of both cameras 15. Other keys of the computer keyboard 4 serve to control the operation of other modes.

After taking photographs of all cars 6 remotely, information files are transferred using keyboard commands to the memory unit 12 of the computer 4.

The “Video Recording” mode is carried out from the moment the train enters the control zone until it leaves it in about 6-10 minutes. The captured frames can also be viewed by the operator in real time on the computer screen 4. In case of detection of any commercial malfunction, the wagon number is marked in the inspection log. This car is then additionally checked or immediately detached from the train. Information from cameras 15 is recorded in memory blocks 16 and can be re-viewed on a computer 4 connected to server 17 of the ACS for managing the infrastructure of a commercial economy. In this case, violations of loading conditions, theft of goods and traffic safety are detected.

Also, commercial car malfunctions include:

the presence and serviceability of fillings and constipation;

open or not door, hatches;

breaks, holes and other signs of hacking; in the walls and on the roof;

tilt and skew of the body;

cargo displacement;

good packaging;

leakage or rash of cargo;

the remains of unloaded cargo;

correct loading and securing of goods;

traces of theft of cargo, etc.

The clarity and range of the image of the frame is selected from the conditions of the perpendicularity of the optical axes, the focal length and camera angles 15 to the removable surfaces of the car 6. The installation of an electric drive 9, focusing the camera 15 and fixing its position in the mount 20 has a great influence. The tripod socket 18 is hinged. For this, the rack-and-pinion mechanism of the electric drive 9 is mounted on the support 1 and rotates the camera 15 in a transverse vertical plane. An example is a drive for remotely opening doors and cameras.

The installation of cameras 15 on the supports 1 should be selected so that their optical axes on one and the other sides are respectively perpendicular to the intersection line of the extreme point of the lower dimension (CT _NG ) of the floor of the near side wall of the car 6 and the extreme point of the upper dimension (CT _VG ) the far side wall of the car 6. On the frame of one camera 15, one side wall and part of the roof of the car 6 are obtained. On the frame of the other camera 15, a symmetrical picture of the other side wall and part of the roof is obtained. In open cars, for example, open wagons, one side wall and the inside of the body are obtained in the frame. Platforms with cargo are viewed from the sides by fully symmetrically mounted cameras 15.

The electric drive 10 when photographing to press the "Start" button of the camera 15 translates the working body forward and backward. In addition, the camera 15 automatically from the computer 4 is switched on and off. Application to turn on and off the remote control is not excluded.

The actuator 11 mounted on the axis of the rotary head of the camera 15, puts the mode "Photography" in the mode of "Video". In the case of using all ten modes of the position switch on the camera 15, this servo rotates it by an angle of 36 °. In two modes, it provides 180 ° rotation.

Maintenance of cameras 15, including turning it on, charging batteries, installing video cards, wiping the lens, adjusting and adjusting, and also servomotors, must be carried out daily, monthly and annually depending on the need and amount of work. To protect against rainfall, a protective cover 19 is installed above the camera 15.

The device will allow the station to record the wagon number, type of wagon, wagon packaging, permitted carrying capacity and cargo loading scheme.

Using the proposed device will improve the quality of inspection of passing cars by simplifying the design and reduce the cost of its installation at freight stations.
