National Environmental air quality monitoring network
The national environmental air quality monitoring network consists of "urban stations","national environmental air background monitoring stations (background stations)","regional stations" and "key regional early warning platforms". At the end of the 12th Five-Year Plan, China had built a well-equipped, wide-coverage, comprehensive project and international environmental air quality monitoring network. Its related work included special inspections of operation and maintenance quality, and the monitoring data could reflect the air quality of various places, such as the air quality rankings of different cities in different months.

The relationship between camera focal length and monitoring range
The focal length of the camera lens determined the monitoring angle and distance of the camera. The relationship between the two was as follows: the smaller the focal length, the larger the monitoring angle, and the closer the distance could be seen; the larger the focal length, the smaller the monitoring angle, and the farther the distance could be seen. For example, a 2.8MM lens could see a 100-degree angle from a distance of about 5 meters; a 3.6MM lens could see an 80-degree angle from a distance of about 10 meters; a 6mm lens could see a 50-degree angle from a distance of about 15 meters; an 8mm lens could see a 38-degree angle from a distance of about 20 meters; and a 12mm lens could see a 26-degree angle from a distance of about 35 meters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The railway network camera narrates
The railway network camera plays an important role in ensuring the safety of railway transportation. I. Intelligent recognition camera for railway displacement 1. ** Create a background ** - Due to natural factors (such as earthquakes, mudflows, etc.) and human factors (such as construction, aging equipment, etc.), the railway line may be displaced, which will threaten the safety of train operation and the safety of passengers 'lives and property. Therefore, it is necessary to monitor the railway displacement, and the railway displacement intelligent recognition camera came into being. 2. ** Function and features ** - ** Real-time monitoring **: Able to collect track data 24 hours a day, allowing the management department to keep track of the situation at any time and improve response speed. - ** High-precision identification **: Based on AI algorithm, it has a high recognition accuracy rate, effectively reducing false alarms and improving data reliability. It is very important for making maintenance plans. - ** Multi-dimensional analysis **: A large amount of accumulated historical data can be used for trend analysis, such as analyzing the changes in the orbit state during the rainy season and dry season, providing scientific basis for decision-making, and also to improve maintenance strategies and improve the service life of the line. - ** Widely applicable **: Not only suitable for ordinary railway lines, but also widely used for track monitoring in high-speed railway, viaducts and other special environments. - ** installation location **: Usually installed in critical sections, such as bridges, tunnels, and slopes, which are prone to displacement. Its core function was to automatically detect whether there was deviation or distortion in the orbit by shooting the orbit in real time and combining it with a deep learning model. When an abnormal orbital position was detected, the system would immediately issue an alarm and record relevant data for subsequent analysis and processing. II. The railway video surveillance camera provided by Dahua 1. ** Type of product ** - It provided integrated spherical cameras, integrated hemisphere cameras, fixed gun cameras, pan-tilt gun cameras, laser pan-tilt gun cameras, uncooled infrared thermal imaging cameras, gun and ball integrated cameras, panoramic cameras, and other equipment. A large number of products were deployed at railway stations, lines, sections, bridges, tunnel entrances, and various key locations. 3. Other railway-related cameras 1. **RTA 8836F HD Camcorder ** - It had functions such as railway wifi recorder, camera flashlight, GPS, etc. In terms of price, it was 1480 yuan to buy 1 - 9 pieces, and 1400 yuan to buy 10 or more pieces. The place of origin was Changzhou. 2. ** Haikang DS -2cd6510db-i camera ** - It was a waterproof day and night car network camera with 1.3 million pixels. It was suitable for railway vehicles. The price was 3000 yuan per camera. There were many lens specifications to choose from, and the working temperature range was-30 ° C ~60 ° C. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Global shutter network camera
The global shutter network camera, also known as the global exposure camera or frame exposure camera, was a camera device that used global exposure. Its unique global exposure method could provide clear and stable images when shooting high-speed moving objects. This camera was especially suitable for the following scenes: 1. Astrophotography: Although astrophotography usually uses long exposure to capture the stars and celestial bodies, global shutter network cameras can play an advantage when shooting fast-moving celestial bodies such as meteors and satellite transit. It can reduce the blurring caused by celestial motion and capture clearer images. 2. High-speed motion scenes: It can significantly reduce or eliminate motion blur and rolling shutter effects. It is suitable for shooting high-speed motion scenes such as sports events, car racing, flight performances, and wild animals, ensuring that the captured images are clear and smooth. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
wireless bridge network camera
The wireless bridge played an important role in the use of the network camera. For example, in elevator video surveillance, the wireless bridge can be used to transmit the surveillance video data of the network camera. In terms of installation, the elevator bridge comes with a POE power supply. The POE port on the power supply can be connected to the POE port on the equipment using the network cable to supply power to the equipment. The computer room side (receiver side)'s POE power supply Lan port (or the device's Lan1/Lan2 port) can be connected to the local area network switch, and the camera side (transmitter side)'s POE power supply Lan port (or the device's Lan1/Lan2 port) can be connected to the IP (network camera) and other devices at the same time. When installing, the black case is connected to the switch or NVR on the computer room side, and the white case is connected to the IPC on the camera side. During networking, the bridge at the end of the elevator car needs to be set to client mode to convert the video data of the network camera from electrical signals to wireless signals; the bridge at the end of the elevator shaft is set to AP mode to connect directly with the NVR through the network cable, and the received wireless signal is directly converted into a wire signal and transmitted to the NVR. And before installing it in the elevator shaft, the bridge had to be matched in advance. At the same time, in order to ensure the transmission quality, it was necessary to avoid the interference of environmental factors as much as possible. During installation, it was necessary to ensure that the bridge was installed directly to avoid the obstruction in the middle of the bridge. The installation position should not be close to the corner of the wall as much as possible to avoid the interference of multi-path reflection on the signal. In the connection part of the equipment, such as the network bridge, the network cable connection part of the POE and the network camera, it needs to be waterproof and dust-proof. The connection part of the network cable and the network bridge generally needs to be wrapped with two to three layers of waterproof tape. The connection part of the network cable and the network camera also needs to be wrapped with two to three layers of waterproof tape or insulated tape. All the power connections should be insulated as much as possible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
