Project Introduction
In order to greatly improve the safety of traffic roads, efficiently investigate and punish illegal vehicles, reduce human labor, and realize full-process automation, Shenzhen Baolong Industrial Park has introduced a road traffic smart license plate recognition system in the park.
The system is based on video triggering and can capture and identify one or more vehicles in the video stream in real time. In addition, video detection technology is used to automatically capture various illegal vehicles in designated lanes, automatically recognize vehicle license plates, and compare data with management databases to find targets and record vehicle license plates and their colors, vehicle speed, and passing time in time. , models, etc., while the police remind law enforcement officers to check suspicious vehicles. Not only that, the system provides database support, network support, on-site alarms and other work modules that can fully automate the entire process. Using this system, not only can greatly improve the efficiency, but also greatly reduce the human labor, and automatically complete the efficient identification of license plates.
system requirement
The intelligent license plate recognition system can be divided into three parts: front-end information collection system, communication network transmission system, and central management application system. The front-end information collection device converts the collected data into digital Ethernet. The format is transmitted over industrial Ethernet to the back-end monitoring and management center. All video and detection data are integrated into the dedicated TCP/IP network at the center to achieve real-time monitoring and storage. And detection application communication network transmission system needs to use Gigabit Ethernet, can transmit a large number of photos and video files can adapt to harsh field applications, such as anti-electromagnetic interference, etc.Moxa solution
In the communication network transmission system, the information collected by the front end of the intelligent license plate recognition system is based on a reliable and stable Gigabit industrial Ethernet for data transmission. The system selects Moxa EDS-510A/518A series gigabit network management redundant industrial Ethernet. The switch transmits high-definition video signals collected by high-definition digital cameras in the field and data collected by other detection devices to the back office management center through industrial Ethernet. Gigabit network transmission capabilities allow real-time transmission of data and video images, greatly improving the capture, supervision, and tracking of illegal vehicles.
In this application, the Gigabit Ethernet port of the Moxa EDS-510A/518A managed industrial Ethernet switch can be used to set up a Gigabit redundant ring Turbo Ring, and the healing time is <20ms, which ensures the simultaneous transmission of data and video Image Gigabit Ethernet is reliable and stable. In addition, the EDS-510A/518A managed industrial Ethernet switch can be set up through web browsers and the Windows utility to make the entire installation process and maintenance more rapid and accurate.
In addition, because the application site is outdoors and the environment is rather harsh, the Moxa EDS-510A/518A supports a wide operating range of -40 to 75°C that is fully applicable to the field environment. In addition, the product has an IP30 protection rating and is certified by a variety of EMSs. Its industrial design greatly meets field applications. The EDS-510A/518A managed industrial Ethernet switch can also be automatically alarmed by E-mail, relay output, etc., enabling the application engineer to quickly troubleshoot.
Not only that, but for some serial devices, Moxa also provides NPort 5230 serial device networking server. At the application site, it can connect RS-232/422/485 serial devices to Ethernet, and it has Moxa's patented automatic data flow function. (ADDCTM), all serial ports come with 15KV ESD protection to ensure data transmission and communication stability.

Why Moxa?
EDS-510A/518A series switches can form a Gigabit Ethernet network to fully meet the large bandwidth requirements of video dataWide temperature design of Moxa switches, anti-electromagnetic interference design can fully adapt to harsh environments
The fanless and low-power design of the EDS-510A/518A series switches ensures reliable and stable operation of the equipment. Its MTBF is more than 20 years.
EDS-510A/518A series switches can also send fault alarm information through E-mail, Relay, OPC data, etc. SNMP Trap can also effectively capture the fault point. Engineers can not only manage and configure the EDS-510A/518A series by Web. Switch, and can monitor the status of each port of the network in real time through network monitoring software integrated with SNMP OPC Server software
