Zhan Guyue said: "There are many strange places in this town. At first, I saw a group of people behaving strangely. I saw glasses showing numbers. I encountered the river flowing backward."
Dong Chu said: "Now, the situation of the river's reverse flow is basically clear. There is still a question, who made these digital glasses."
Fu Shuo said: "What kind of sensor is used for detection? Can it be directly used for water detection?"
Water sensors are usually used in water quality monitoring, sewage treatment, aquaculture and other fields. Types include the following: pH sensor, dissolved oxygen sensor, temperature sensor, turbidity sensor, ammonia nitrogen sensor, water level sensor, salinity sensor, water pressure sensor, COD sensor.
But I don’t know how this data is detected by the sensor. According to everyone's speculation, a mapping sensor is used to transmit all data to the glasses.
But where is this sensor placed? It is impossible to place a sensor next to every object, nor to place a sensor in the water at certain distances.
Zhan Guyue said: "This is reminiscent of a quantum sensor. The principle of detecting pressure is to use the principles of quantum mechanics to measure small changes in matter. Specifically, it converts small deformations of the object being measured into atoms and molecules. Or the energy state changes of electrons, and the pressure of the measured object is determined by measuring these energy state changes. This technology can achieve high-precision, high-sensitivity, non-contact pressure measurement."
If the parameters of the entire city are detected, then the main dimensional data, temperature data, and pollutant data can be detected. Radars, laser rangefinders, infrared cameras, drones, etc. may be used to conduct comprehensive measurements of the city, collect a large amount of data, and process the data through computers to generate a three-dimensional model and various parameters of the city.
But what is detected here is pressure data, not dimensional data.
Strain gauges can be used for pressure testing, but there are also some non-contact measurement methods.
Laser ranging: Using a laser rangefinder, you can measure the distance and displacement of an object, and then calculate the pressure on the object. This method is suitable for measuring the pressure of smaller objects.
Infrared thermal imaging camera: The infrared thermal imaging camera can detect the thermal radiation of an object. By measuring the thermal radiation intensity and temperature distribution of the object, the pressure on the object can be calculated.
Sound wave detection: By detecting the sound wave signal emitted when an object is stressed, the pressure on the object can be calculated. This method is suitable when the pressure of smaller objects needs to be measured, but the detection needs to be carried out in a quieter environment.
Photoelastic method: The photoelastic method is a method of calculating the pressure on an object by measuring the strain on its surface. It is suitable for measuring the pressure of smaller objects.
Dong Chu said: "According to my understanding, this kind of large-area mapping sensor mainly includes infrared thermal phase sensors and acoustic wave sensors."
"The collection and processing of these data are at the city level. I think the data is first transmitted to a central server. The processing results are then sent to the glasses."
Zhan Guyue said: "Yes, the digital computing network should be processing this data."
Fu Shuo said: "But the amount of data is very large. How can we improve the processing speed?"
There are several ways to improve the speed of big data processing: Distributed computing: Using a distributed system, big data is distributed to multiple computing nodes for parallel processing, thereby increasing the computing speed. Memory computing: Store data in memory to avoid frequent disk read and write operations and improve data processing speed. GPU acceleration: Using graphics processors for calculations can accelerate certain computationally intensive tasks, such as image processing and machine learning algorithms. Compression and encoding: Compressing and encoding data can reduce the overhead of data storage and transmission, while also increasing the speed of data processing. Data partitioning: By partitioning data according to certain rules, data in the same area can be allocated to the same computing node for processing, improving computing efficiency. Data filtering: When processing big data, you can first perform data filtering to filter out the required data, reduce the burden of data processing, and increase processing speed. Data preprocessing: Before big data analysis, data preprocessing can be performed, such as data cleaning, deduplication, normalization, standardization, etc., to reduce the amount of calculation and increase the processing speed.
Sent to the server for processing, the speed will be very fast, much faster than edge computing.
Fu Shuo said, "Do you know who made these glasses?"
Zhan Guyue said: "We don't know, otherwise we go back and ask Tang Yihuai."
They returned to the conference room.
Zhan Guyue said: "Mr. Tang, there are some questions. Do you know? This digital glasses can encode and decode information in the computing network. Who made it?"
Tang Yihuai said: "Xu Baishan."
"This does use mapping sensors. It includes long-range infrared light wave and acoustic wave sensors. It only collects the data that can be detected, and the accuracy is not guaranteed."
Dong Chu said: "We have been guessing for a long time. Finally we understand."
The digital glasses made by Xu Baishan can view the data of each object and can be used as a tool to connect to new computing networks.
The water distribution stones were washed away from the upper reaches, probably in the Teng River, and were brought to several towns in Shuicheng. Under the influence of the water distribution stone, the water flow is also affected.
Pollutants from electronics manufacturers' factories polluted the lake water, causing aquatic planters to reduce production and receive complaints. Their profits were significantly reduced and they even lost money. Electronics manufacturers were also fined. Continuing hot and dry weather has led to reduced tea production.
Contacts are hackers who want to gain access to computing networks.
Zhan Guyue said: "Okay, now these things are clear."
Fu Shuo said: "If this digital eye can be used, the water flow simulation should be more accurate."
Zhan Guyue said: "Yes, you bring this first. Then, we will improve the water flow simulation program together. With the help of the computing power of the new computing network and the data collection capabilities of the digital glasses."
Fu Shuo said: "Thank you very much for your help during this trip."
Zhan Guyue said: "Yes, we are all colleagues. We have also heard about what Mr. Qi plans to do in Tengcheng. Managing the river is also a major event that is beneficial to the citizens."
Fu Shuo originally wanted to talk about all the strange things he encountered in Shengshi City, and he didn't know what he would encounter in Tengcheng. But things are quite complicated, and I can’t explain them clearly for a while. Wait until these things are resolved, then chat with Zhan Guyue.
