The invention relates to methods and devices alarm about theft, violation of sealing doors, hatches, etc., on railway transport in the movement of trains using TV cameras.

Known Spacelab [1].

The disadvantage of this method is its low productivity.

It is widely known use of television cameras for surveillance of protected objects, in particular, on the railway transport [2]. Television cameras are used to monitor trains during their formation in parks and dismissed slides.

However, the known TV setup does not allow to detect unauthorized access, breach of the seal, break the door, the roof of the car, etc.

Known industrial television installation (PTU), produced by industry and designed for surveillance [3]. The choice of their parameters is dictated by their intended purpose, while the range of their main characteristics is the number of rows of the decomposition, the number of reproduced gradation of brightness.

The drawback of plants is that they require continuous operator's participation in the monitoring object.

A device for surveillance rails on the railway [4], which contains a video camera installed under the frame of the car, with halogen lighting lamp. The resolution of the video camera 430 tovani. The disadvantage of this device lies in its narrow specialization.

Known video motion [5], which provide a record of the intrusion in a wide range of sizes and speeds of the movements of objects invasion, and the range of the fixed displacement does not depend on changes of illumination in the control zone. In the famous VMD for one period between updating a record, choose from the calculation to avoid false positives, for example, due to displacement of the sun shadow is a few hundred cycles comparison that allows you to block a range of movement from the high speed to the slowest.

With the sensor output signal is supplied to the processing device, in which the amplitude-temporal selection signal, the measurement of informative parameters and conversion of measurements into digital form. The received data is fed into a specialized computing device, in which the accumulation and processing of incoming information according to predefined classification algorithms. The device search cells automatically search and selection of individual cells of the drug, as well as the offset of the object stage of the microscope after the end of the measuring cycle parameters for each cell. Logical device determines the sequence of the search and measurement of cells. Visual display device is used for visual control during configuration and operation of the complex. The results of the analysis of parameters of cells and classification of the drug are fixed on the output device (digital signage, tsifropechatayuschee device and so on).

The measuring part of the complex "Frame" is an independent television analyzer structure image which act on the stage, in addition, the parameters of the PTU does not correspond to the task of image analysis of a moving train.

However, its technical nature of this decision may serve as a prototype of the proposed. The objective of the proposed method and device is to enable the timely detection of unauthorized access of a moving train composition.

The device operates as follows.

Manual control of the testing process.

With the approach of the train to the Park arriving camera overview 10 generates a video signal perspective images of trains, in particular, the roofs of moving trains. The specified signal arrives at the visual display device 12, the operator observes the images and visually captures otkryt imaging of small objects (leads, and so p. ) generates a video signal bystromenyayuschimsya in its field of view of the search objects that cannot be directly detected by the operator visually. The video camera 11 through the input VI and the output of the eighth switch signal 13 is fed to charge digital video recording 15 where it is converted into a digital code and a sequence of video frames in a digital form recorded on a computer hard disk recording device 16. When detecting violations of cargo on the screen of the visual display device 12, the operator by means of a switch 14 connects the camera overview 10 via the input V and the output of the eighth switch signal 13, and through cost digital video recording 15 writes the frame of the damage in the memory recording unit 16 of the computer PC-2.

After passage of a train in the Park of arrival, the operator analyzes the recorded information using a recorder 16 to the monitor 22 (ICD-4).

The semi-automatic mode control process control.

With the departure of the train from the station of departure camera overview the TC-1, located in relation to passing the composition is identical to the camera a General overview of the LC-3 in pairs is via the input I and the output of the fourth switch signals 4 and through cost digital video recording 6 is recorded on a computer hard disk recording device 7. After the passage of trains in the Park arriving at the camera overview 10, the latter likewise generates a video signal corresponding to the image arriving composition. This video is a sequence of frames corresponding to the sequence of cars (either tanks, platforms, etc.) composition. This sequence records: "one shot - one wagon is provided by counter 17 cars (MF-2), which via the input V and the output of the eighth switch video signals 13 and through cost digital video recording 15 the signal is recorded in the computer memory of the recording device 16. The operator in the Park arrival includes both computer recording devices 7 and 16 in the playback mode, and the signals from the memory computers arrive at the inputs IX and X identifying unit 18 by means of the synchronizer 19 is provided synchronization signals, and after they pass through a squarer 20 on the screen internals-4, in its neighbouring halves, formed the image of identical fragments of controlled composition at the exit from the station of departure and upon arrival at the Park arrival. When this logical device 21 is not involved. Comparing these images, the operator identifies understand the terms of the decision task, the broadcast image in the computer memory recording device 7 can be made with cameras detailed review of the LC-2, located in relation to passing the composition is identical to the camera a detailed review of the TC-4 arrival in the Park. In order to avoid the accumulation of errors in a frame-by-frame analysis because of the differences in the speeds of the trains in the parks of departure and arrival video produced by the signal counter 9, 17 cars. Each sequence begins after the actuation of the counter, and the previous accumulated error is set to zero.

Automatic control of the testing process.

In automatic mode, the work included a logical device 21, in which of the Quad 20 receives television frames of the reference video image obtained in the Park departure, and taken in identical conditions of television frames received on arrival in the Park. In this case frames of reference and received in the Park arrival of the videos are numbered, with the help of Quad combined their beginning, and then there is their logical processing by a special algorithm. In particular may be used by the program VideoTest version of 4.0.

For greater reliability and ease logical analysis of all the televised images are shot under identical conditions, i.e., the speed of the train in the Park departure and pagenow should provide a number of special requirements.

When selecting the geometry of the installation of cameras overview of TC-1 and TC-3 should be guided by the following provisions:

- cars must run on the camera, the operator detects the screen in the upper part of the image break rooftops or open doors and hatches. As the crowding of trains on the camera the specified image is moved to the bottom of the screen, at the same time increasing in size, allowing the operator to make a final conclusion about the existence of a breach of cargo;

- the width of the roof of the car in the image should match the width of the bottom border of the screen, which provides optimal observation:

- the angle of the axis of the camera must be such that the residence time of the considered point of the car in a field of view of the operator was not less than 5 s, which provides reliable solution to the problem of detection and recognition.

When selecting the geometry of the installation of cameras detailed review of the LC-2 and LC-4 should be guided by the following provisions:

- the camera should be perpendicular to the surface under study, because it provides a constant sharpness of the considered point in the process dicta observations in the field of view of the cameras should be the same to avoid "overshoot" of a given point, as well as to ensure the possibility of its observation on the border of the frame, and in his field at an arbitrary point of observation.
