Policy background
Recently, the Law of the People´s Republic of China on the Prevention and Control of Noise Pollution officially came into force, making the corresponding provisions on the roaring noise and other problems, and proposed to take effective measures to prevent and reduce noise pollution. According to the "2021 China Environmental Noise Pollution Prevention and Control Report", in the past 10 years, noise pollution complaints have continuously accounted for the top two of the total environmental complaints, reaching more than 38%, among which traffic noise accounts for 21.7% of the acoustic environmental noise sources in urban areas, which is the largest public noise source. The application of portable all-in-one machine is an important measure to reduce the existing traffic noise pollution.
The use of portable all-in-one machine is another innovative practice of technology in the field of urban transportation. For traffic law enforcement modified car Fried street management problem, especially in the situation of increasing number of motor vehicles, the driver Fried street behavior not only affects the normal travel of citizens, is not conducive to build a harmonious and civilized social environment, so the use of advanced technology to strengthen the driver Fried street snap governance is very necessary. Portable fried street car to capture the all-in-one machine was born.
product presentation
Osn portable Fried street capture machine adopts integrated design, highly integrated microphone array, hd camera and lithium battery, a single tripod erection can be used, facilitate the traffic department according to demand, flexible deployment and command scheduling, anytime, anywhere, namely out of the use, effectively support urban motor vehicle illegal Fried street centralized crackdown, create a more quiet urban road traffic environment.

Product characteristics
Flexible use
l Built-in hd camera unit, highly integrated;
l Using a robust acoustic detection and acoustic positioning algorithm;
l System weight is less than 8 kg, safe and stable, flexible scheduling;
l The whole set of equipment is light and portable, directly through the tripod, single person can be deployed anytime and anywhere;
l Full power life of 8 hours, the power supply can be removed and replaced.
Portable management
l Built-in Wifi / 4G module, flexible networking;
l Automatically save the audio and video data before and after the blast street;
l Equipped with a 10.1-inch display terminal, real-time data view;
l Mobile and computer terminals receive real-time view capture data.
core advantage
l Embedded integration scheme: to realize the integration of the explosive street capture system, without industrial control machine, low comprehensive cost;
l Installation and debugging is convenient and environmental protection: installation and debugging are completed in 1H, and "0" noise pollution during the installation process;
l Real-time online monitoring of equipment status: real-time fault monitoring of equipment, microphone self-inspection, real-time monitoring of equipment online status;
l Multi-redundant high availability design: in the case of some abnormal microphone condition, the system can still work normally;
l The detection and capture accuracy of the Ministry of Public Security is 98%: the high-precision robust sound source positioning algorithm, the system capture rate is greater than 98%, and the effective rate is greater than 98%;
l Flexible switching of capture applications: it is the first in the industry to realize the flexible switching of horn capture and street car capture applications without changing the terminal equipment.
system function
l At the scene through the mobile phone, computer, tablet, real-time view of the blast street vehicle high-definition evidence photos and "sound video";
l Automatically screen the sound of the fried street. When there is a motor vehicle exploding in the street, automatically capture high-definition pictures, identify the illegal vehicle license plate number, and record at least 2 seconds to record the audio and video before and after the fried street. For non-blast street noise, such as brake sound, engine sound, speech sound, automatic filtering, to avoid false positives;
l Capnap records can be browsed and exported at any time, the whole system is easy to operate;
l It can cooperate with the police for on-site law enforcement, and use them as auxiliary evidence, or export evidence pictures and videos and upload them to the illegal processing platform as off-site law enforcement evidence;
l Capnap pictures automatically superposition illegal forensics information (illegal time, illegal place, driving direction, illegal type, security code, etc.).
Fried street car capture management platform
The management platform of exploding street cars, linked with the traffic police law enforcement system, uploads the evidence of violations to the traffic police law enforcement system, which can display and manage in real time on PC and mobile terminals, effectively solve the traffic problems such as the difficulty of obtaining evidence of the exploding street car traffic signal, and improve the level of urban civilization management.
