In summary
High-speed "electronic eyes" deter traffic violations
In a bid to enhance road safety and reduce traffic violations, the Chongqing Expressway Second Detachment has deployed advanced surveillance technology known as "E-Eye" on key sections of the Shanghai-Ningbo and Shanghai-Chengdu Expressways. This high-tech system continuously monitors highway traffic around the clock, contributing significantly to improved road safety in the region.
According to recent data, traffic accidents and incidents involving casualties along the northeastern expressways of Chongqing have seen a remarkable decline. In the first half of this year, there were 382 traffic accidents recorded, marking a 26.14% drop compared to the same period last year. Notably, casualty accidents fell by an impressive 66.7%, reflecting the best safety performance in recent years.
To further strengthen traffic management, Chongqing’s high-speed law enforcement agencies have been actively implementing smart supervision strategies. Since last year, 146 high-definition gantry cameras have been installed across expressways, with 36 of them located in the northeastern area. As a result, the percentage of traffic violations detected through remote enforcement has risen sharply—from about 20% at the start of the year to over 50% now.
In addition to deploying advanced technology, the authorities have also integrated social and technological resources to create a collaborative command system for highway monitoring. The Chongqing Expressway Second Detachment's duty center is now co-located with the Northeast Regional Center of the Chongqing High-Speed Group Road Network Center. By leveraging 2,077 surveillance cameras installed by the Chongqing High-Speed Group, real-time monitoring of the roads is now possible.
In the first half of this year alone, the Chongqing Expressway Second Detachment conducted online inspections, identified and addressed 697 major violations and safety hazards, and responded to over 10 sudden events such as landslides caused by heavy rain. These efforts are playing a crucial role in ensuring safer and more efficient travel for drivers in the region.
A dissolved oxygen analyzer/meter is a Water Quality Monitor that is used for online control and digital measurement of dissolved oxygen in water. It consists of a controller and a sensor to achieve continuous real-time monitoring of dissolved oxygen values ​​in different water bodies. The controller of our dissolved oxygen analyzer is responsible for receiving the data signal from the sensor, can display a large amount of information, can have relay and 4-20mA current output functions, and also has an RS485 interface, supports Modbus protocol digital transmission, and presents it to the user in an intuitive way (such as digital display, chart or alarm signal). The Dissolved Oxygen Sensor part adopts fluorescence measurement, which has the advantages of no reagents, no oxygen consumption, and real-time measurement.
Dissolved oxygen (DO), as an indispensable key element of life activities in water bodies, refers to oxygen molecules dissolved in water. It is the main source of respiration of aquatic organisms and is directly related to the health and stability of aquatic ecosystems. High dissolved oxygen levels can support the survival of more types of aquatic organisms and promote biodiversity. It also helps the natural degradation process of organic matter in water bodies and reduces the accumulation of pollutants. In aquatic environments, oxygen saturation is a ratio of the concentration of "dissolved oxygen" (DO, O2), to the maximum amount of oxygen that will dissolve in that water body, at the temperature and pressure which constitute stable equilibrium conditions.
The importance of monitoring dissolved oxygen is that it is not only one of the key indicators for assessing water quality, but also an important basis for judging the self-purification capacity of water bodies and the health of ecosystems. Low dissolved oxygen levels may cause aquatic organisms to suffocate and die, destroy ecological balance, and even cause environmental problems such as eutrophication and black and smelly water bodies. Therefore, timely and accurate monitoring of dissolved oxygen content is of great significance for preventing water quality deterioration, protecting water resources, and maintaining ecological balance.
Due to its high precision and real-time continuous monitoring characteristics, dissolved oxygen analyzer plays an indispensable role in water quality monitoring in many industries:
Environmental protection: Installing online dissolved oxygen analyzers in natural water bodies such as rivers, lakes, reservoirs and sewage treatment plant outlets can monitor water quality changes in real time, timely detect and warn water pollution incidents, provide scientific basis for environmental protection departments, and effectively protect the water environment.
Aquaculture: Dissolved oxygen is a key factor affecting the growth and health of aquatic animals. Installing analyzers in aquaculture ponds can accurately control dissolved oxygen concentrations, optimize the breeding environment, improve breeding efficiency and product quality, and reduce economic losses caused by hypoxia.
Drinking water treatment: Ensuring drinking water safety is the basis of public health. Online monitoring of dissolved oxygen helps to evaluate the effectiveness of water treatment processes, such as ozone disinfection, biological filters, etc., to ensure that water quality meets standards and ensure the safety of drinking water for residents.
Industrial cooling water management: In the industrial field, especially in the power and chemical industries, the dissolved oxygen content of the cooling water system directly affects the corrosion rate of equipment and the cost of water treatment. Through online monitoring, the cooling water treatment plan can be adjusted in time, the equipment life can be extended, and the operating cost can be reduced.
Hot spring and swimming pool management: For recreational water bodies such as hot springs and swimming pools, the monitoring of dissolved oxygen helps maintain the cleanliness of the water, prevent the spread of diseases, and improve the user experience.
The dissolved oxygen analyzer/meter plays a vital role in water quality monitoring in many fields such as environmental protection, aquaculture, drinking water treatment, industrial cooling water management, and leisure and entertainment with its efficient and accurate monitoring capabilities. It is an important tool to ensure water quality safety and promote the sustainable use of water resources.
