2 is an overall configuration diagram of a transmission system for outputting a screen for multiple inputs of an automated facility water management system according to an embodiment of the present invention.

As shown in Figure 2, the system of the present invention,

Bit rate processing means 400; is configured to include.

The repair facility described in the present invention may be, for example, a pumping station, a drainage station, or a sluice gate, and the water management automation system includes an image remote monitoring and control system, which is filed by the inventor and registered with the Korean Patent Office. No. 0472081, "Remote monitoring and control system of drainage drainage lock," and No. 0625885, "Digital remote monitoring and control device for processing analog data and digital signals."

In general, in the management of repair facilities, various input elements generated in the field are defined as variable inputs. For example, video, sound, broadcasting, control, and measurement data may be used.

Loss of sound and data (measurement, control, etc.) was unavoidable when the transmission speed was transmitted to the central office (central monitoring and control unit) through a single line due to the regional characteristics of the repair facility. .

However, the above configuration can solve the problem of loss of sound and data.

That is, the variable bit rate processing means is configured to ensure the quality without loss of sound and data during transmission.

As a result, the multi-input data transmitted from the field can be displayed on the screen of the central monitoring control means.

For example, the display (image display), the listening broadcast (sound), the control screen, and the measurement screen on the monitor screen can be displayed without additional manipulation in the set area.

As shown in FIG. 2, the multi-input means 100 includes any one of an image acquisition device 110, an acoustic acquisition device 120, a broadcasting device 130, a control device 140, and a measurement device 150 in the field. It will include one or more devices.

At this time, the field data collecting means 200 collects the image, sound, control data, and measurement data of the field from the multi-input means at predetermined time periods.

Thereafter, the field data analyzing means 300 analyzes the data collected by the field data collecting means, assigns a code signal to each of the analyzed images, sounds, and data, and calculates the total data size.

The multi-input means, on-site data collection means, and on-site data analysis means are 'image remote monitoring and control system', filed by the inventor of the Korean Patent Office No. 0836825 and 'No. 0472081' remote monitoring and control system of the drainage lock And No. 0625885, 'Digital Remote Surveillance Control Device for Processing Analog Data and Digital Signals,' will not be described in detail.

The variable bit rate processing means 400, which is a main component of the present invention, acquires the data processed by the field data analysis means, compresses the image frames, and variably adjusts the number of image frames, thereby simultaneously widening the sound and data. The communication is sent to the central monitoring control means (500).

The variable bit rate processing means is characterized by processing the image data in a variable bit rate to ensure the quality of sound and data.

This ensures the bandwidth of sound, control, etc., even when the image data increases, and transmits the reliable data to the central monitoring control means through a single line, watching the site through CCTV, listening to the sounds around the site and the sound of machine operation. Alert broadcasts and control are possible without quality degradation.

Therefore, as shown in Figure 3, while reducing the communication line cost wasted by the conventional transmission using a separate line is to provide an advantage that it is convenient to use as an output for the multi-input.

The following describes the operation in detail.

The type of data collected at the site where the repair facility is installed includes image data through the image acquisition device (fixed camera, speed dome camera, etc.), acoustic data through the sound acquisition device (microphone, etc.), broadcasting device (AMP, speaker, etc.). It has various types of input such as voice data through, control data through a control device, state or measurement data through various measuring devices (water gauge, open meter, voltage, current, temperature, etc.).

Subsequently, the screen display in the central monitoring control means is shown in Figs.

That is, the image is displayed in the area 10 shown in FIG. 5, the measurement data value is displayed in the measurement area 20, the control screen is displayed in the control area 30, and the area (which is shown in FIGS. 6 to 7). 40) will display the current volume level.

In the water management automation system described in the present invention, the on-site data collection means 200 is set through the various types of multi-input data through RS 232, RS 485, and RJ 45. Data is collected at regular time intervals.

At this time, the field data analysis means 300 assigns a corresponding code signal to each of the image, sound, and data analyzed by analyzing the multi-input data, and calculates the total multi-input data size.

In this case, when the variable bit rate processing unit 400 sends the multi-input data to the central monitoring control unit, the variable bit rate processing unit 400 compresses the video signal through MPEG-4 or H.264 video compression algorithm. Bit rate allocation is variably performed by the processing of the components shown in FIG.

The MPEG-4 image compression algorithm is well known to those skilled in the art, and a detailed description thereof will be omitted.

Figure 4 is a block diagram of a variable bit rate processing means of the transmission system for the screen output for the multi-input of the repair facility water management automation system according to an embodiment of the present invention.

As shown in FIG. 4, the variable bit rate processing means 400 includes:

A transmission bandwidth measuring unit 410 for periodically measuring a bandwidth of a wide area communication (WAN) and calculating a bandwidth that can be transmitted (uploaded);

When the size of the entire multi-input data analyzed by the field data analysis means is more than the bandwidth range of the video bandwidth meter 420 for calculating the video bandwidth for the video transmission minus the bandwidth occupied by the sound and data of the code signal;

An image sampling unit 430 for performing sampling on the image collected by the estimated image transmission bandwidth;

After variably adjusting the number of sampled video frames, an information transmitter 440 is provided for transmitting audio and data to broadband monitoring means at the same time.

The transmission bandwidth measuring unit 410 periodically measures the bandwidth of the wide area network (WAN) to calculate the bandwidth that can be transmitted (uploaded).

In general, the communication speed of the area where repair facilities are installed is relatively lower than that of urban areas, which is why multi-input data transmission cannot guarantee the loss of data.

When the size of the entire multi-input data analyzed by the field data analysis means is greater than or equal to the bandwidth range, the image bandwidth analyzer 420 calculates an image bandwidth for image transmission by subtracting the bandwidth occupied by sound and data among the corresponding code signals. .

In this case, the image sampling performing unit 430 performs sampling on the image collected by the estimated image transmission bandwidth.

In the case of video, the sensitivity is relatively low even though the number of frames per second is smaller than the sound and data.

In other words, due to the nature of the repair facilities, there are not many operating elements such as cars and people as in urban areas.

The information transmitting unit 440 variably adjusts the number of sampled image frames, and simultaneously transmits audio and data to broadband monitoring means.

In this case, the sampling is preferably Gaussian pyramid sampling.

This ensures that voice and data can be assured of quality without signal loss.

The Gaussian pyramid sampling is performed by the image sampling performing unit. For this purpose, the image sampling performing unit includes:

A pyramid image generator (not shown) for generating a pyramid image;

A background model generator (not shown) for generating a background model based on an LBP histogram for the pyramid image provided by the pyramid image generator;

And an object splitter (not shown) for dividing the detection object in the background model provided by the background model generator.

Gaussian pyramid sampling is a repetitive filtering and subsampling of the original image to obtain successive images with reduced resolution.

This speeds up the computational speed and feature point detection through image processing on the reduced image.

The background model generator performs a function of generating a background model based on an LBP histogram for the pyramid image provided by the pyramid image generator and providing the object model to the object splitter.

That is, in order to generate a solid background model, the background model is trained based on the LBP histogram (local binary pattern histogram), which speeds up the performance of object recognition and provides a very stable recognition rate.

The object dividing unit divides only a detection portion in the background model provided by the background model generation unit, for example, only a portion that is shaken when a vibration occurs, and only a fire portion when a fire occurs.

Providing only the detection object image processed by the object splitter will result in a higher capacity image processing speed.

The variable bit rate processing means of the present invention is for efficiently adjusting the capacity allocated per unit bit.

In other words, when the amount of video data in the midday sunlight or heavy rains is large, the transmission speed is lowered and the control is not performed properly.

Accordingly, the variable bit rate processing means ensures the bandwidth of sound, data (control, measurement) and the like even when image data increases, thereby enabling reliable transmission and control of measurement data.

Conventionally, when video data increases, audio and data are discarded. However, the present invention adopts a method of variably reducing the bits containing video data information while ensuring the bits containing the audio and data information even if the video data increases. Will be.

This is because the discarding of voice and data can be sensitively detected whether the user is discarded, but it is relatively difficult to recognize the variable reduction of the video data such as the number of video frames or the video bitrate.

In the case of the system applied in the prior art, the manager directly collects the data of the relevant institution and determines that the manager needs to control the flood reduction facility with empirical knowledge. And the device to be controlled.

However, in the system of the present invention to which the variable bit rate processing means is applied, when the event occurs, that is, when the water level data reaches a dangerous level, the camera automatically moves to the corresponding level position, or when the intrusion is detected in the facility, the camera moves to the important facility position. It is convenient to operate because it consists of a single system for reporting, listening, broadcasting and controlling.

In addition, by using the LBP histogram method and the image Gaussian pyramid method for setting the background image model, it is also possible to prevent the traffic according to the image data by minimizing the image data information and transmitting only the moving object information in real time. .

On the other hand, the end-to-end network usable bandwidth measurement technique can be largely divided into a single-hop gap model technique and a self-induced congestion technique.

The single-hop gap model technique is a technique for reducing available modeling to a single hop with a network bottleneck link and measuring available bandwidth by analyzing output intervals of received packets when packet pairs are transmitted at regular intervals.

This technique has the advantage of quickly finding available bandwidth because it uses a small number of packets.

In addition, the size of the measurement packet is small, there is an advantage that does not put a heavy load on the network.

However, if the fixed bandwidth of the bottleneck link is not accurately measured, an error may occur greatly. If the bottleneck link and the congested link are different links on a path, an error may occur.

It is a technique to measure the available bandwidth by analyzing the queuing delay.

This technique has the advantage of finding the available bandwidth regardless of the location of the bottleneck link or the congested link because the available bandwidth is measured by the delay experienced by the measurement packet.

Therefore, the model is more suitable for the actual network situation. However, since the self-congestion causes the measurement packet itself to load the network, the measurement takes a long time.

However, in the present invention, the sound and data among the data (video, sound, data) transmitted to the central management means are guaranteed to be 100% quality, and are loaded in the bandwidth first, and the queuing delay observed from the receiving side while increasing the transmission amount of the video packet. The analysis utilizes a self-congestion-causing technique that measures available bandwidth, thus eliminating the network load for separate measurements.

I will explain with an example.

Required data transfers per second per data video Above water management program video standard 76.8KB / F voice Normal quality condition: 13Kbps, excellent quality condition: 32Kbps data 9.6Kbps ~ 19.2Kbps (varies depending on data communication method) Upload speed requires 128 Kbps for smooth transfer.

Based on the data in Table 1, the upload speed of the field (remote station) communication must be at least 128 Kbps to transmit all images, sound, and data to the central office.

If the upload speed is less than 128 Kbps, the image becomes a still image with no frame change or an intermittent frame change.

This is because the priority of bandwidth allocation is in voice and data, and video occupies the rest.

Therefore, the transmission bandwidth measuring unit 410 periodically measures the bandwidth of the wide area network (WAN) to calculate the bandwidth that can be transmitted (uploaded).

If 200Kbps was measured by measuring the upload speed, first allocate 32Kbps of voice bandwidth and 19.2Kbps of data, and then allocate 148.8Kbps to the video bandwidth.

As a result, through the configuration and operation as described above, by receiving multiple inputs such as video, sound, broadcasting, control, and measurement in repair facility management, by guaranteeing the bandwidth of sound, control, etc. even when the image data increases in the variable bit rate processing means, By transmitting reliable data to the central monitoring control means through a single line, the site is viewed through CCTV, the surrounding sounds and machine operation sounds are heard, and the guidance and warning broadcasts are made for control. To provide the last name.

It will be appreciated by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not restrictive.
