Introduction of the application of industrial computer in electronic monitoring of stadiums
Gymnasiums are areas where people gather and behave. Such areas are densely closed, and because they are sports venues, dangers are prone to occur. In order to better prevent dangers before they occur, the installation of electronic monitoring systems in stadiums is to solve this problem. The usefulness of the problem is missed; as a well-known industrial computer supplier in China, let's introduce the application of EVOC industrial computer in the electronic monitoring of stadiums for friends.
Through the monitoring system, the on-duty management personnel can inquire about the dynamic situation of each tense position in a comprehensive and timely manner, so as to take precautions before it happens. When there is an emergency, it is beneficial to quickly investigate the scene and take action. It can also intensively supervise the development of the situation and instruct the action. It can provide strong evidence and record for later analysis through videography, and further improve the level of technical defense construction and management.
1. System overview
With the development of science and technology, the current electronic monitoring system has transitioned from the ancient camera tape monitoring system to the hard disk camera monitoring system, and then the electronic monitoring system has also entered the digital light signal period from the simulation light period. The advanced hard disk camera system can store clear images on the computer hard disk for easy access, review and digital archives at any time.
According to the characteristics of the stadium, the monitoring system can be divided into: monitoring center, venue monitoring, corridor monitoring, elevator monitoring, garage monitoring, entrance and exit monitoring, and venue peripheral monitoring.
Construction of monitoring server in the monitoring center, it is important to complete audio and video digital conversion, storage, monitoring image performance, system control and other things; venue monitoring, corridor monitoring, elevator monitoring, garage monitoring, entrance and exit monitoring, venue peripheral monitoring, construction of cameras, sensors, experience The camera completes the collection and transmission of audio and video, and completes the input and output of alarm lights through sensors and buttons.
two-system principle
The monitoring system can be divided into four parts according to the function: on-site collection, transmission, control and performance record. The relationship between the various parts is shown in the following figure:
Among them, the on-site collection part is installed on the site, which includes cameras, lenses, protective covers, brackets and electric PTZs. Its mission is to record the subject and convert the captured video signal into an electric signal. The mission of the transmission part is to transmit the light signal from the live camera to the control room, which usually includes cables, clear drive buildings, etc. The performance and documentary screen convert the electric light signals from the scene into images to be displayed on the supervisory building, and can preserve the image; therefore, it mainly includes supervisory and storage buildings. One-sided control is responsible for the control of all buildings and the handling of image lights.
3. System plan
According to the current monitoring situation and application needs, this monitoring application system plan guides the mind to take ", applicable, economical, and reliable" as the basic principle. This system plans to use: IPC-8421 plus IPC-6114P12 plus FSC-1717VN plus Pentium4 3.2G CPU plus DDR2 500 512MB plus 320G hard disk plus 48X burner plus TM6204BT from YONGS Intelligent Co., Ltd.
YONGS IPC-8421 is a 4U industrial-grade chassis that can provide up to 14 hard disk spaces, which can fully meet the needs of a large amount of video image storage in the monitoring system.
YONGS IPC-6114P12 is an embedded industrial-grade backplane that provides 12 PCI expansion slots, which can fully meet the expansion needs of the monitoring system.
YONGS FSC-1717VN is a global industrial-grade motherboard based on Intel875 chipset PICMG specification, high 800MHz FSB, supports Socket478 Pentiun-4 and next-generation Prescott CPU, and supports HT (Hyper-Threading) technology to improve system performance and feedback speed. , support dual-channel DDR266/333/400, 2 DIMM slots, high support 2GB memory; powerful on-board ATI 9200 8X graphics acceleration controller, independent 64MB DDR video memory; on-board 10/100M Ethernet controller, RJ -45 ports; 2 SATA hard disk ports, with a transfer rate of 150Mbps, to meet the need for hard disk transmission bandwidth; 5 USB2.0 ports to meet more and more USB interface peripherals; support AT/ATX power supply.
?FSC1717VN plus P4 3.2G CPU plus 512MB DDR2 memory plus 320G hard disk can fully provide the super speed and performance and large storage space required by the monitoring system.
?TM6204BT is a 4-channel audio and video card, which can complete the conversion of 4-channel monitoring audio and video.
4. System Features
