Prospects for the development of automated systems for ensuring public safety for the Smart City system.
The largest system integrator of the federal level, one of the operators of the Safe City project and occupying a leading position in many regions in this area, within the framework of the Smart City of the Future project, presented a report on the topic “Development of automated systems for ensuring public safety”.
To solve these problems, interactive services are being developed, which combine the functions of access video surveillance services and a locking device. The result of this project is the transmission of video images from several cameras installed on the call panel of the intercom and inside the entrance to the TV receiver of residents, as well as to the data processing and storage center of special city structures for working with information technologies of a settlement or region. On the basis of these services, it is also possible to provide additional services to city residents, for example, emergency communications in case of emergencies. The addition of the ability to analyze the video data stream in a programmatic way allows you to automate the detection of violations of public order, analyze information from visual information sensors and decide on how to respond. This system is implemented using the developed hardware and software complex, which is based on an information processing board on high-performance processors and FPGAs.
Intelligent analysis of video data flow for the Smart City system.
The infrastructure of large cities has a complex multi-level organization. It consists of many subsystems – transport, telecommunications, power supply systems, water supply systems, as well as many others that function and interact with each other. To control the operation of all city systems, ensure the safety of citizens and all vulnerable points of the city infrastructure, obtain and archive information about all important events and promptly provide this information to all interested services, not separate video surveillance sensors are needed, but an integrated information system that can collect, combine , analyze and group disparate data from multiple sources. This is exactly the system that the Smart City project represents.
The capabilities of the “Smart City” system.
Data from street cameras, supplemented by analytical software systems, significantly expand the capabilities of the “Smart City” system.
Algorithms implemented on the company’s hardware, processing data on FPGAs and microprocessors, allow us to extract useful information from significant data streams and minimize the human factor in the urban video surveillance system.
The use of video data analysis and decision-making based on embedded algorithms within the Smart City project allows solving the following tasks:
• automatically monitor the quality of the video signal using service sensors, which helps city services and other telecom operators to avoid significant payments associated with fines for non-working cameras;
• indexing large-scale volumes of video data using metadata from sensors and subsequent search by analytics events greatly simplifies the work of both various bodies in analyzing events and system operators when identifying and classifying events;
• situational analytics of situations, such as signaling devices for stopping vehicles, crowds of people, people falling on the rails, movement of citizens against the stream, and others, reliably work on city streets, as well as at transport facilities.
Description of the hardware. Data processing board CT325
The basic module CT325 is designed to create systems for collecting and processing video signals based on industrial computers of the server platform. The module is used in systems with direct data transfer to a PC or with digital data processing in a Xilinx Kintex 7 microcircuit with an XC7K325T crystal. The flexibility of the module configuration is determined by the implementation of control functions, data streams and digital processing algorithms on the XC7K325T FPGA. This FPGA chip provides support for SDRAM memory, PCIe v. 2.0, Fast Ethernet. The clock signal switching system provides reception of two clock frequencies, reception of a frequency from the built-in programmable generator of the synthesizer, as well as output of any clock signals to the FPGA.
Data exchange with the external environment can be realized via USB and Fast Ethernet interfaces. For loading and processing data with the Xilinx Kintex 7 XC7K325T system and microcircuit, the PCIe x1 v. 2.0. Data exchange is carried out using the SERDES implementation. The system is supported by the LINUX operating system.
