Recently, what are the latest application developments in many fields related to the application of sensor technology in China? Take a look at the following three newsletters.
New on-board laser mobile measurement system appeared on the scene, data map
1. New mobile measurement system with various sensors to assist land survey
A portable on-board laser scanning system mounted on a motorcycle is running fast when surveyors are riding motorcycles and driving in the countryside. When the collected data is combined with the processing system, the real scene can be restored in real time at the terminal.
On January 20th, at the speed China Zhizhi Summit held in Nanjing, a three-dimensional laser scanning device, satellite positioning module, inertial navigation device, vehicle encoder and other sensors were integrated into one system. bright.
The system can be easily installed on SUVs, motorcycles or other mobile carriers. Data map
It is understood that mobile measurement technology is one of the most advanced technologies in the field of surveying and mapping. It is a system integrating three-dimensional laser scanning equipment, satellite positioning module, inertial navigation device, vehicle encoder and other sensors. Quickly acquire 3D point cloud data of the feature in the mobile driving state. It is reported that the system has the advantages of firmness, stability, calibration, small size and light weight, which is convenient for users to use, maintain, store and carry. Easy to install on SUVs, motorcycles or other mobile carriers.
2. Nanchong City Museum capping construction: deployment of sensor monitoring hydraulic lifter
On the afternoon of January 22, a “steel hat†weighing 7,800 tons was brought up at the site of the Nanchong City Museum project in Baituba Road, Nanchong City, Sichuan Province. After a steadily rising 15 hours, it reached the end of 31.5 meters from the ground. It marks that the steel structure roof of the Nanchong City Museum project, which was built by China Wuye Group, has been upgraded in place, and the project construction has achieved a major stage victory.
The steel structure roof was successfully placed on the four load-bearing cylinders. Data map
It is understood that the construction area of ​​the Nanchong Museum project is about 49,150 square meters. During the construction of the project, the construction party broke the original “basic-main body-roof†construction procedure, first constructed four load-bearing cylinders, set up the roof, and then unfolded the construction of the basement and main body.
It is reported that in the overall lifting operation of the steel structure roof of Nanchong Museum, the technicians are equipped with a total of 8 hydraulic pumping stations, equipped with 32 lifting points, each equipped with a 350-ton oil cylinder for lifting and lifting speed control. At 3 meters per hour. At the same time, the technicians also install sensors in each load-bearing cylinder area. By reading these sensor data, the computer control system can realize independent real-time monitoring and adjustment of each hydraulic lifter.
3. Zhejiang Haining opened the first set of intelligent dust removal system for construction sites
Recently, the first intelligent dust removal system for construction sites in Haining City, Zhejiang Province was opened at a certain construction site in the city. Under unsupervised conditions, the system can perform real-time spraying according to the air quality of the construction site. At the construction site, sensors with different functions are hidden in the construction site. On the other hand, an electronic monitoring display is displaying detailed data, including data such as pm2.5 and pm10.

According to reports, this intelligent dust removal system can display monitoring data on air quality and linkage with spray dust reduction facilities. It can monitor the air quality of the entire site in real time. If the dust exceeds the specified value, it will automatically turn on the spray, which means that the computer can accurately judge and quickly reduce dust.
Since last year, the company has started to develop a smart dust removal system for construction sites, which was officially put into use this year and became the city's first intelligent dust removal system for construction sites. Once the monitoring data reaches “light pollutionâ€, the system will automatically open the road sprinkler facility. If the monitoring data is above “moderate pollutionâ€, the system will immediately open the spray facilities of the tower crane and the outer frame.
According to reports, this system can not only monitor the air quality of the entire site in real time, but also upload the monitoring data to the network. Project management personnel and competent authorities can know the air quality of the site or view the dust image on the site through the mobile APP. The surveillance video will be automatically uploaded to the cloud platform, which can be saved for one month, and can be directly retrieved when needed.
