Panoramic lens 1-1 television cameras intended for forming the optical image of the circular review (circular image). As a technical solutions for panoramic lens 1-1 can be offered panoramic lens / mirror lens design which is patented in Russia by domestic experts from the Moscow state University of geodesy and cartography [2].

The photo of the ring image formed panoramic lens shown in Fig.7. Angular field in space items for this lens is 360° in azimuth and can reach 75-80° in elevation.

The optical block 1-2 is designed to parallelize the optical image output from the panoramic lens 1-1 on target each of the two TPA.

The optical block 1-2 (see f the, 3) contains a beam splitter 1-2-1 and corrective filter 1-2-2, thus a beam splitter 1-2-1 made in the form of a prism with two beam-splitting faces arranged at an angle of 30° with the first beam-splitting face of the prism is the input of the beam splitter, the second beam-splitting face of the first output beam splitter, the third face of the prism, which is located at an angle of 60° with respect to the first face, the second output of the beam splitter, and corrective filter 1-2-2 made in the form of a prism with one spectrometrically face, which is the input correction filter is located at an angle of 30° with respect to its second face, which is the output of the correction filter, the first output beam splitter 1-2-1 optically connected to the input correction filter 1-2-2, the second beam-splitting face of the prism beam splitter 1-2-1 installed close to spectrometrically faces of the prism correction filter 1-2-2 whose output is the first output of the optical unit, the second output of the beam splitter 1-2-1 - the second optical output unit and the input of the beam splitter 1-2-1 input optical block.

In the future can be developed and specialized technical solution television panoramic lens integrated into the design of the beam splitter and a corrective filter, i.e., blocks 1-1 and 1-2 are made in one optical the second device.

As in the prototype, the first TPA 1-3 and the second TPA 1-4 is made on the basis of technology CCD having a circuit organization "line wrap" or "line-personnel transfer. The first TPA 1-3 in the daytime operates in mode "TV", forming the output periodic color composite video signal in accordance with the television standard. The second TPA 1-4 in the evening and at night in the absence of violations in the area offers black-and-white video signal is also in the "TV". Upon registration of the offender TPA 1-4 switches automatically to "MONOSHOT", i.e. in the mode of formation of the video snapshot duration one standard field, as proposed in the invention [3] and implemented practically in the product [4].

The detector 1-5 movement, as in the prototype, the appearance of a field of view of the second TPA 1-4 moving objects generates a signal RM - signal motion detection active low.

A logic level "0" at the output of the detector 1-5 supported and upon termination of change of the input signal. Restore the original "1" at the output of the detector 1-5 is performed by feeding on its control input the command "reset alarm" output "IRDY" the second sensor TPA 1-4. The detector 1-5 movements can be performed as a separate unit of the television camera 1, and the composition of the second TPA 1-4 (see, for example, the invention [5]).

Unit 1-6 switching, as in the prototype, is designed to generate at the output of one of the two input video signals. The presence of a logical "1" at the control input unit 1-6 provides the broadcast signal output from the first information input, and when this input is logic "0" is broadcast on the signal output from the second information input.

The selector 1-7 clock, the first peak detector 1-8, PHI 1-9, block 1-10 sample-hold, comparator 1-11, the second peak detector 1-14 and ADC 1-15 execution is indistinguishable from the same blocks of the prototype. Note that the signal at the output of the comparator 1-11 has an active level to low level.

Shaper 1-16 duration savings can be made on the basis of multistage combining a binary counter, for example, domestic chip CIE (see [6, S. 238]). Installation input shaper 1-16 equivalent inputs appointment-install SO-S3 counter enable input the enable input of this operation SE, the control input is the carry-in inputCinx, clock input - input on tact With, and the output - output transferCinthe . It is assumed that for the selected chip reversible counter at its inputU/Dthe counter is set to logical "1", i.e., the account is in the direction of "the Code". Note that the control input and the output of the shaper 1-16 are active low voltage level.

The one-shot 1-17 can be performed using the standby multivibrator circuits CAG(see [6, S. 282]).

Each of the blocks 1-19 and 1-20 separately is a logical trigger device RS-type active high voltage level on the control input.

The inverter 1-12, element "And" 1-13 and control "OR" 1-18 are logical devices unambiguous concepts.

As block 4 can be used for your personal computer, in which, as in the prototype, a Pentium III processor (or better) operating system Windows XP/SE/ME, but may be, of course, has a more modern version of Windows 7 or 8.

According to the claimed solution is entered into the computer and additional hardware product - to-Board video.

Fee video installed into a free slot on the motherboard of a computer, performs the following functions:

p> the operation modes of the television system (as in the prototype);

- analog-to-digital conversion "ring" color or black-and-white video signal coming from the output video television cameras;

- enter the "ring" digital color or monochrome video signal in a memory;

- convert output "ring" frame black-and-white image or "ring" frame color image in the respective rectangular frames by reading the video signal from the main memory for executing the correction of geometric distortion of the corresponding area of the panoramic image.

All of these functions are implemented through software. Note that the last two operations are exactly the same as it was proposed in the invention [7].

Closed-circuit television system "day-night" (see Fig.1) works as follows. The television camera 1 is installed in a fixed position, for example by means of potestative (Fig.1 it is not shown).

Scroll in the operation of closed-circuit television system three modes:

- "day" (mode 1);

- "night" (mode 2);

- "alarm" (mode 3, which may accompany both mode 1 and mode 2).

Regardless of the mode of system operation "ring" the optical image of the observed scene, Faure, the dummy panoramic lens 1-1, on the optical path of the first beam-splitting face of the prism beam splitter 1-2-1, the second beam-splitting face of the prism beam splitter 1-2-1, spectrometrically face of the prism correction filter 1-2-2, the second face of the prism correction filter 1-2-2 projected in the visible spectral range on photomixing first TPA 1-3. At the same time optical frame panoramic lens 1-1 through different optical paths: the first beam-splitting face of the prism beam splitter 1-2-1, the second beam-splitting face of the prism beam splitter 1-2-1, the third face of the prism beam splitter 1-2-1 in the whole spectral range (visible and infrared) is projected onto photomixing second TPA 1-4. It should be noted that the infrared spectrum of the last optical image is additionally enhanced by the luminous flux reflected spectrometrically facet prism filter 1-2-2 in the direction of the third face of the prism beam splitter 1-2-1.

When power is both sensors television signal TPA 1-3 and TPA 1-4 default start working in the "TV".

In the photoelectric transformation output "LV1" TPA 1-3 is formed of a composite color video signal, and the output "LV2" TPA 1-4 - composite black-and-white video signal in the same scale.

For monochrome video output "LV2" detector 1-dvizheniya carries out monitoring of the situation, performing frame-to-frame comparison of adjacent frames. Hereinafter we will use the plots shown in Fig.4-6.

The selector 1-7 highlights from the composite color video output "LV1" (see Fig.4A) and lowercase HR clock (see Fig.4B), and PHI 1-9 produces within each human quenching pulse following with a period of Ttoimpulses record and reset (see, respectively, Fig.4B and Fig.4G).

A peak detector 1-8 with a period of Ttomeasures the level of the video with TPA 1-3 (see Fig.4D), block 1-10 sample-hold remembers it at time Tto(see Fig.4E), and the comparator 1-11 evaluates the output voltage of the unit 1-10, comparing it with a threshold voltage Up, (see Fig.G).

In the "TV" input "select mode" ("MS*") of the other sensor - TPA 1-4 is set to high level (logic "1"). Note that a high logic level is maintained on the input signal accumulation frame" ("FI*"), at the input of the request signal of the image" ("IRQ) and output the ready signal of the image" ("IRDY*"). Simultaneously, a logic low is present at the output of TPA 1-4 - "the handshaking signal of the image" ("IACK") and at the output of the inverter 1-12 - signal motion detection" ("RM").

The first RS-flip-flop 1-19 and the second RS-trigger 1-20 are in state "0". Therefore, the inverse of the output of the RS-flip-flop 1-19, support is moved a logical "1", and shaper 1-16 locked the control input high logic level and does not consider lowercase sync HD out*. Output "video" ("LV2") sensor TPA 1-4, is formed of a composite black-and-white video signal by the television standard.

For monochrome video output "LV2" detector 1-5 movement carries out monitoring of the situation by performing frame-to-frame comparison of adjacent frames.

Suppose that the television system is operating in the daytime, i.e., in the "day" ("1"), and moving objects in the control zone are missing. Then the comparator 1-11 does not change its state according to the output, while maintaining the logical state "1" (see diagram in Fig.G), and there is a high level voltage at the output of the detector 1-5 movement. Therefore, at the output of element "And" 1-13 also present a logical "1", and the output unit 1-6 switching, and, consequently, on the output of "LV" television camera is transmitted color composite video with TPA 1-3.

Color composite video output "LV" is transmitted on the communication line 2 on the receiving end of a television system, and then goes to the computer 4 on Board video.

Coming on Board video of "the ring" video color image is digitized, and then is introduced (recorded) in blocks of computer memory. Further implements the I conversion output "ring" frame color image in the respective rectangular frames by reading the video signal from memory.

Suppose that when designing closed-circuit television system developer pledged that the current angle (γg) is presented to the operator a panoramic image is 60° horizontally. Then the relation (1) "ring" frame should correspond to the six "rectangular" frame (n=6). This means that you have 6 conditional fields in space "ring" of the frame (see Fig.8).

Therefore, each "ring" record frame image is converted to 6 "rectangular" frame, which can be offered in the form of the current sequence (see Fig.9) the operator 4 computers, the leading monitoring protected area.

Let at time t0another result of the interframe comparison in the detector 1-5 movement captures the appearance of the offender. Then at its output ("RM*") appears low voltage level, and the output of inverter 1-12 - positive differential voltage (see Fig.5A), which is the communication line 2 is transmitted to the input of the shaper 3. As a result, the receiving side of a television system is provided sound and light alarm.

Television system enters a "1+3".

At the same time in the television camera 1 positive differential voltage at the output of inverter 1-12 translates RS-triggers 1-19 and 1-20 in "1" state, in which operates the reset peak detector 1-14 and runs the one-shot 1-17.

The one-shot 1-17 generates at the output a pulse signal (see Fig.5B), the duration of which t0...t1is the interval resolution operations prior record-setting numbers in the counters shaper 1-16.

During the interval t0...t1a peak detector 1-14 measures the current value of the signal. The constant voltage output from the peak detector 1-14 converted later in ADC 1-15 from analog form to digital form and fed to the installation inputs of counters shaper 1-16.

By the time t1(see Fig.5B) record-setting this number in the counters shaper 1-16 must end.

It should be noted also that since t0block 1-6 switching already passes on the video "LV2" from the sensor TPA 1-4.

Starting from the moment t1at the output of the element OR 1-18, and, therefore, on the input "MS*" sensor DS 1-4 level is set to a logical "0".

Therefore, the television camera 1 since t1goes from "TV" mode "MONOSHOT". Additionally, we note that since t0the control input of the shaper 1-16 is a logic low, i.e., the lock on the input tape.

Counters shaper 1-16 count increment data, and its output, since t1placed low logical level (with the. Fig.5g or Fig.5e). Therefore, the sensor TPA 1-4 status for accumulating information charges depending on the lighting control zones in the whole spectral range. Monochrome image signal of the CCD image sensor has a linear scale level depending on the light conditions (γ=1), and it is assumed that this output "video" excluded the impact of automatic gain control (AGC).

Note that these signs are a necessary condition for the proposed solution of the television system.

The duration of the accumulation in the sensor TPA 1-4 set optimal according to the criterion of maximum signal-to-noise ratio for video running snapshot of the image, which is achieved by preliminary calibration television cameras (see below).

If the violation is in the protected zone occurs at night, the TV system in the "2+3" is similar, differing only in that the duration of the accumulation in the sensor TPA 1-4 in the night time will be considerably higher than in the daytime.

After completion of charge accumulation in the sensor DS 1-4 (see t2in Fig.6A) is reset counters shaper 1-15 and installation of the RS-flip-flop 1-19 in state "0" and, therefore, the re-locking of the former (1-16 of the control input.

The counters shaper 1-16 setting is correspondingly zero number, and the sensor TPA 1-4 enters the state of nanocopoeia", because the input "FI*", starting from this moment, is formed of a high logic level.

Next to the photo chopper CCD TPA 1-4 briefly served the high level voltage, allowing the transfer of charge packets from the photodiodes in the potential well formed in the vertical CCD registers. Recall that the vertical CCD registers of photomeson matrix CCD with line wrap" insensitive to light through the insulating masking, so the migrated phototherapy accumulated frame can be stored there for quite a long time.

If the charge transfer is the value of τ1after its completion output "IRDY*" sensor TPA 1-4 is formed of a single pulse (see Fig.6b) - tone image.

This signal on the communication line 2 is transmitted to the receiving side of the TV system and supplied to the computer 4. In the computer with a delay τ2installed in the interface block interface Board video, produces an output signal of the query image (see Fig.6g), which is on the wire 2 is fed to the input "IRQ*" sensor TPA 1-4 television camera 1.

Further, when the low level signal of the query image coincides with the end of the nearest line sync pulse (see the IOM is t 3, Fig.6b), starts the readout of the charge relief of a data frame, which continues during the interval t3...t4. As a result, the output video ("LV2") sensor TPA 1-4, and, consequently, the output of "video" ("LV") television camera 1 is a single video frame (see Fig.6E). Note that the duration of this signal, taking into account human quenching pulse is Ttoand corresponds to the period fields on television standard.

In parallel with the video signal of a single frame output "IACK" sensor TPA 1-4 produced a single positive pulse signal acknowledgement (confirmation) of the image (see Fig.6D), the duration of which is the interval (t3...t4).

Next, the signals "LV" and "IACK" broadcast on the communication line 2 on the receiving end of a television system, and there come on Board video computer 4 of the operator.

The incoming signal "IACK" provides automatic failover in the running computer program in the tab "Picture". Therefore, in the interval (t3...t4) writes "the ring" monochrome video signal of a single frame ("LV") in your computer's RAM. Further, similar to converting a single "ring" frame 6 "rectangular" frame and save them in the folder of computer p is mate.

Add to this that in the television camera 1 at time t5(see Fig.6g) low level signal "IRQ*" ends. Emerging positive voltage sets the RS-trigger 1-20 in state "0". In the high logic level voltage is maintained at the entrance "MS*" sensor TPA 1-4, and the television camera 1 mode "MONOSHOT"returns to "TV".

Note that at time t6emerging positive differential voltage signal IRDY*" (see Fig.6b) resets alarm detector 1-5 movement, restoring the level of logical "1" at its output.

In the television system switches from the operation mode "2+3" to "2".

If then, as a result of the daily transition "night-day" illumination on the object increases, then the inventive system automatically returns to the mode will be "2" in mode "1".

Let us return to the question of the optimal accumulation of information charges in the sensor TPA 1-4 in the "MONOSHOT".

This is done by calibrating the TV cameras.

First television camera 1 should operate in the "TV". Before the optical unit 1-1 is set to the test table, and its illumination in white Emaxprovides maximum amplitude of the video signal generated by the sensor TPA 1-4, i.e., compliance with a criterion of maximum relationship is ignal/noise.

Next, the television camera 1 is switched to the "MONOSHOT". When the voltage input through the installation inputs to the counters shaper 1-16, adjusted so that the maximum number of accounts and the occurrence of the output pulse transfer from the high-discharge duration of the accumulation of the CCD image sensor would be one field on television standard, i.e., Tto(20 MS).

It should be noted that to perform these measurements need storage oscilloscope, and the measurements are rather time-consuming.

Then, if the illuminance of the subject, E1will be less than Emaxwhen you reach the maximum number of accounts of the output pulse of the transfer will appear later, at time t2(see Fig.5B), and the duration of the accumulation of the CCD will be (t1...t2)>Tto.

If the illuminance of the subject to reduce even, i.e., E2<E1proportionally later, at time t3(see Fig.5D), appears the momentum transfer and accumulation duration (t1...t3) will increase accordingly.

It should be noted that the automatic selection of maximum accumulation timeTnmandKwith athat corresponds to extremely low lighting the items E minthe subject, as the duration of storage in the CCD accumulated charges should take into account technological limitations of the photodetector at a current density thermogeneration (dark current) and the readout noise of the Converter charge - voltage".

So technically reasonable maximum count total time savings - storage at normal temperature for modern CCD is 1...10 seconds

With these considerations is selected and the maximum capacity of the counter shaper 1-16, which provides long-term accumulation of the photodetector in TPA 1-4.

Evaluate the technical result of the proposed solutions.

The technical result of the invention is that the computer operator has the option to create a circular overview of the situation in the zone of the protected object, increasing the spatial angle in azimuth to a value of 360°.

An additional result of the proposed solutions closed-circuit television system can be considered the ability to create on its basis a complex of physical protection systems due to the possibility of successful writing as in local area network and the Internet. An example of a structural scheme for the organization of such a system is shown in Fig.2. Note that the arrows on the lines of the diagram illustriou the t signal transmission image.

Here the computer 4 of the operator is the driver of alarm 3 alarm, and the computer performs the additional function of a server. Through the use of this system router 5, the information stored on this server, it becomes available and any other user of the computer on the local network, such as a computer 7.

The modem 6 to provide the video information and the Internet, i.e. it can act on the remote user's computer, such as computer 8.

Currently, all the blocks of this solution developed or may be developed by the domestic industry, therefore, should be considered the present invention corresponding to the requirement of industrial application.
