In-vehicle monitoring systems are widely used in public transport, long-distance passenger transport, and taxis. The system is generally composed of three parts: a vehicle terminal, a transmission network, and a monitoring center. It prevents theft of vehicles, anti-robbery, driving route monitoring, and video inside and outside the car. Image transmission, accident response, command and other functions.

Adopts embedded operating system and processor, and effectively combines the latest video compression and decompression technologies in the IT industry, 3G wireless communication technology, USB communication technology, GPS global positioning technology, advanced automotive power management technology, GIS geographic information technology, etc. Real-time security monitoring for all types of vehicles around the clock. Such products can carry out wireless audio and video real-time transmission, audio and video synchronization video, global positioning, and its host set aside a variety of interfaces, taking into account the needs of users, convenient and IC truck carrier, vehicle display screen, passenger flow statistics system , signal priority control system and other vehicle equipment connected. Most of these products are small in size, low in power consumption, noiseless, easy to install, and stable in function. They can be widely used in buses, buses, trains, and subways.

When you are on a bus with relatively smooth traffic, you will often hear warm tips from on-board monitoring to alert bus drivers to the situation of the road, warn that the speed of the vehicles may be too fast, greatly reduce the possibility of accidents, and ensure the safety of public travel. . This is the role of on-board monitoring.

In recent years, the rapid development of the logistics industry has promoted the growth of logistics vehicle teams. How to effectively manage these vehicles has also become a top priority for managers. The on-board monitoring system can solve many problems very well. Vehicles such as anti-theft, speeding, driving routes, and when they arrive at their destinations can all be informed by the dispatch managers in the first place.

For some truck drivers to privately resell the in-vehicle fuel problem, it can also play a very good monitoring role. The oil level sensor of the fuel tank can be connected to the monitoring system. When the liquid level suddenly drops, it means that there may be two situations in the fuel tank. One is that the fuel tank is broken, and the other shows that the driver is reselling fuel and the system can immediately issue an alarm.

For the application of on-board monitoring system, it is currently widely used in public transportation. There are few applications for private cars. How to popularize the on-board monitoring system still requires more businesses to promote, allowing users to understand the on-board monitoring system. The importance of With the complexity of modern transportation networks, the significance of on-board monitoring systems is very important. It can not only ensure the safety of travelers, but also analyze the real-time conditions of road traffic.

Vehicle 3G video monitoring and dispatching system is used to understand and master the dynamics of public security in surveillance areas and transport vehicles, to make up for lack of air defense, to protect the safety of passengers' lives and property, to effectively crack down and prevent crimes, and to become an important means of public security management. When investigation and evidence collection and project investigation are conducted, crime space is maximally reduced, deterrence is enhanced, and regional stability and prosperity are maintained.

Real-time monitoring of vehicle transportation process

(1) Real-time monitoring of vehicle transportation process

3ggps car network video server can realize real-time monitoring of multiple information, on-board driving record terminal can be real-time monitoring or random inspection of the vehicle's driving status and other information, the system automatically processing and storage of information, real-time understanding of the vehicle's driving status and operating environment , To find environmental or human problems in a timely manner, including random parking, nothing to ride.

(2) Query of transportation process information

The information of dangerous goods and highly toxic chemical production and transportation enterprises may be inquiries at any time, the release of laws and regulations concerning the management of highly toxic chemicals, and the list of highly toxic chemicals. You can check the name of the shipper, the name of the transporter, the transportation route, the transport-related vehicles and transport-related personnel, the name and quantity of transported highly toxic chemicals, and the validity period of the relevant road transport permit.

(3) Emergency linkage of emergency

Including traffic control at the scene of the accident, evacuation of personnel around the scene of the accident, emergency rescue of the accident, etc., relevant information can be sent to the monitoring command center in real time, facilitating the timely handling of the accident.

(4) Information processing after completion of transportation

After the vehicle arrives at the transportation destination, it can download and query the driving recorder and video file information through the wired/wireless network. The stored image and data information can be printed and played back to facilitate inspection of the vehicle trajectory and system operation log.

(5) Effectively improve services and improve safety prevention

There are some contradictions and controversies between passengers, travelers and crews on long-distance travel. From time to time, companies often get complaints, especially when some passengers get off the train and take away other people's luggage and articles because they are not powerful. The evidence has no way to solve the problem and the company’s image has been greatly affected. After the installation of the video recording system, it can effectively control the behavior of embezzled public funds such as passing passengers and receiving private money and goods, as well as improving service quality.

(6) Improve safety and accident forensics

Long-distance buses have long running times, complicated road conditions and personnel, and many more roads and roads, and are prone to safety problems. In particular, there have been many vicious traffic accidents in the cases of stealing, stealing, abducting, and defrauding during the peak period of the Spring Festival. Drivers' irregular operations and severe overloading have occasionally occurred. Through the network remote video surveillance and video recording system, the passenger transport company and the management department can check the driver's illegality and overload at any time via 3g network remote video, and the video data can be used by the criminals as proof of crime.

(7) Effectively urge drivers to operate in strict accordance with regulations and drive in a civilized manner to improve the safety of driving.

Demand market, onboard monitoring or facing industry changes

As demand continues to diversify, onboard monitoring may face industry changes. There are two main factors, one is internal and the other is external. External factors are the frequent occurrence of accidents in the transportation market. How to better guarantee the safety of people's lives and property is an urgent problem for the entire transportation industry. In order to strengthen the safety supervision of road passenger transport, especially long-distance sleeper buses, the Ministry of Public Security, the State Administration of Work Safety, and the Ministry of Industry and Information Technology issued the “Circular on Strengthening the Dynamic Supervision of Road Transport Vehicles” in accordance with the relevant requirements of the “Safe Production Act.” It is required that the sleeper bus must be equipped with an onboard video surveillance device. The Deputy Minister of Transport also proposed new requirements for the supervision of sleeper buses at the national emergency television and telephone conference for safe production of transportation. Among them, it is required that sleeper buses must be equipped with mandatory on-board video devices, and enterprises should monitor the conditions inside the cars at any time. Driven by the impact of the national policy, the potential demand for the mobile surveillance industry in the car began to gradually show up, and it is believed that there will be a concentrated outbreak in the next two years.

How will the future development of on-board monitoring and innovation develop?

Looking at internal factors again, internal motivation comes from the overall trend of monitoring the market - high-definition and networked, 720P, 1080P or higher resolution surveillance products have become the mainstream of the surveillance market, and networked alternatives to traditional simulation. The transmission method has become the best carrier for high-definition, although at this time the traditional vehicle-mounted monitoring system is still playing a leading role in analog monitoring. However, starting last year, some manufacturers that are brave enough to develop have begun to gradually pilot new high-definition solutions to solve vehicle monitoring. The overall poor monitoring effect of the industry, such as the overseas Axis and the domestic Suzhou Kodak, have entered the field of high-definition on-board surveillance very early. At some domestic exhibitions, high-definition on-board monitoring has resulted in better image effects. The admiration of visitors overturned the problem that the original vehicle-mounted monitoring system could only be seen but could not be seen clearly.

The NVR high-definition IPC monitoring method of the car is beyond the traditional analog monitoring. Some well-known manufacturers such as Suzhou Keda, Hikvision, Shenzhen Ruiming, including Tongzhou Electronics have all launched car NVR systems supporting high-definition IPC access. This shows that high-definition and networking are changing the pattern of this market.

The price factor is also inevitable. The launch of high-definition network cameras will inevitably bring about an increase in the cost of the entire vehicle-mounted monitoring system. This part needs to be controlled and reduced after popularization. On the other hand, the adjustment of 3G tariffs is based on the current high 3G tariffs for various industries. Popularization has a great impact. The 3G traffic generated by real-time video transmission makes it difficult for users, especially users who use large quantities, to take it.

This problem requires not only the promotion of the industry, but also the influence of the government and related functional departments as well as the development of the communications industry itself.

From the development direction of the monitoring market, we can see that the development trend of vehicle-mounted wireless monitoring is moving in the direction of high-definition, intelligence, integration, standardization, and industrialization.

High-definition

The traditional vehicle-mounted industry mainly adopts the structure of ordinary digital video recorders and analog cameras. The advantages are low cost and less attention to other aspects of video surveillance. With the advent of networking and networking, the on-board surveillance industry is gradually moving toward high-end development. Many users are already satisfied not only with manual monitoring, but also with intelligent monitoring. The intelligent analysis system needs to process high-definition images to achieve intelligent effects, otherwise it cannot achieve intelligent processing. The sharpness of the image clarity brought about by high-definition video has a clear advantage in the future on-board surveillance. Obviously, the on-board monitoring of high-definition resolution image effects will inevitably become the mainstream of the future intelligent surveillance market, which will further raise the threshold of the vehicle-mounted surveillance industry and play a positive role in the orderly development of the entire vehicle-mounted surveillance industry.

Intelligent

The advantage of intelligence is that it can provide more value-added applications for the special needs of the in-vehicle monitoring industry. For example, when a law enforcement vehicle is driving, the road surface is bumpy and the image is shaken. For image monitoring personnel, the image is not clear and difficult to obtain. And it is easy to have a sense of fatigue on the screen; however, intelligent screen shake can solve such problems, and in the bus industry, intelligent systems such as passenger flow statistics, face recognition, license plate recognition, etc. can also provide better help for back office operations. .

Integrated

With more and more industry users paying attention to the vehicle-mounted monitoring system, vehicle-mounted monitoring gradually evolves from a single video surveillance to a professional solution. For example, in-vehicle monitoring in the public transportation industry is a part of the overall operation and dispatching system. At the same time as the video monitoring, it also needs other system equipments (gps positioning system, electronic newspaper station, card reader, speed radar, license plate recognition, etc. ) Collaborate. The integration of the system requires the joint efforts of vehicle monitoring manufacturers and market users to produce system-integrated products that meet the needs of industry users.

standardization

The current security hardware is very mature in the industry, but there is still a considerable gap in the construction of software systems. The mismatch of various subsystems and standards are not uniform and cannot be combined together. How to achieve better openness and sharing requires standardization. Promoting industry standardization requires the joint efforts of relevant government agencies and industry players.

Industrialization

Not only will it be tailored to different industry applications, it will also be tailored to specific customer needs. For example, buses, passenger cars, public security law enforcement vehicles, taxis, etc., have good product solutions to satisfy.
