They went to a microelectronics company in the town.
"I am Chaoxin, the boss of electronic products."
"Hello."
"Hello. I heard that Mr. Ying Jiang is here to attend a seminar. I should also attend when I have time."
Dong Chu said: "Are you also interested in mathematics?"
"Yes, I have met Mr. Tang before. He asked me to buy some materials to make a sensor. I can't figure out what it does. It may be a sensor for detecting brain waves and image recognition."
Dong Chu asked, "Have you had any contact recently?"
"No more. He is busy and has not attended industry meetings."
It seems that he didn't know that Mr. Jiang was not in the meeting and Mr. Tang was not contacted.
Zhan Guyue said: "What do you sell here?"
"Commonly used electronic component products include semiconductor components, relays, thyristors, resistors, diodes, transistors, optocouplers, transistors, integrated circuits and connectors, etc."
"Also, processing chips, VR devices, brain wave sensors, and digital display glasses."
Zhan Guyue said: "When it comes to processing chips, I think of self-assembly chips. They have appeared in Shengshi City. It is the smart controller that was discarded in the recycling bin. It controls the mobile garage and performs automatic assembly and Upgrade, install chains to transport cargo parts, install tires to move, and install robotic arms to clamp things.”
"I've heard of it. That time near the garbage recycling station in Shengshi City, self-assembly chips were automatically assembled into a mobile garage. Yonghan and Fu Shuo chased the automatic mobile garage and fought with the car thieves. The car thieves originally wanted to steal a car. Focused field battery.”
Dong Chu said: "This self-assembled chip is quite advanced."
"Yes. We can't do this. It's beyond our design capabilities."
Zhan Guyue said: "Do you think the self-assembled chip calculates independently, or does it receive the calculation results from other controllers?"
If the calculations and thinking are completely performed by the self-assembled chip, then this belongs to edge computing. If distributed computing is performed on many computers, this belongs to cloud computing.
Edge computing refers to an open platform that integrates computing, storage, and application core capabilities on the side close to the source of objects or data to provide the closest service. Its applications are initiated on the edge side, generating faster service responses and meeting the industry's basic needs in real-time business, application intelligence, security and privacy protection.
If you only use cloud computing, you may be unable to access. Some of these errors are related to network conditions and cloud server bandwidth limitations. Due to resource constraints, cloud computing services are inevitably affected by network instability. However, by migrating processing programs closer to users or data collection points, edge computing can reduce the impact of slow computing in the cloud center on applications. coming influence.
But if edge computing is used entirely, this chip may not be able to complete such a large amount of calculations.
Liu Mozhi said: "Is it possible that this chip is connected to a certain computing network through the network? It will have certain intelligence and automated computing capabilities."
Zhan Guyue said: "Is this the digital network created by Mr. Tang?"
Liu Mozhi said: "It's not very similar. The digital network created by Mr. Tang is to simulate reality and use mathematics to describe the real world, but it does not have the ability to perform autonomous operations."
Dong Chu said: "So I think self-assembled chips still have independent computing capabilities. The network signal is not good at the garbage collection station."
"We bought this communication helmet here."
"Yes, we sell VR devices, AR devices, etc."
VR devices usually include components such as virtual reality headsets, controllers, position trackers, microphones, and speakers.
It consists of the following parts: Monitor: A device that mainly displays VR content, usually an LCD monitor. Tracking system: Tracking based on location to display VR content. Gyroscope and accelerometer: Sensors that measure user behavior, such as head shake, displacement, etc. Composite headset: a wearable device that supports the entire VR system. Visual enhancement: Integrate natural visual scenes and virtual scenes to enable users to experience a more realistic environment. Speakers and headphones: Provide sound in the virtual environment.
"What's the tracking device here?"
“Electromagnetic tracking and optical tracking devices are generally available.”
Electromagnetic tracking systems generally consist of electromagnetic field transmitters, receivers and electronic control units, using sensors installed on the human body. The electromagnetic field transmitter uses alternating current or direct current to emit low-frequency electromagnetic fields, and is installed as a sensor receiver on the human body to measure changes in magnetic flux. Both the transmitter and the receiver are connected to the electronic control unit, and the electronic control unit outputs the data captured by the sensor to the computer to calculate the position and orientation of the 6 degrees of freedom of the tracked object or part.
Optical tracking uses head-mounted glasses or a camera placed on the head-mounted glasses to achieve 3D position tracking based on relevant computer vision algorithms. In optical tracking, the camera is calibrated to determine the distance to the object and its position in space.
Dong Chu said: "Also, in the woods, we saw someone selling these digital display glasses, which can display the status of various objects and convert them into numbers."
Digital display glasses are composed of lens screens, processors, cameras, sensors, batteries and other parts. The lens screen can display virtual graphics and text; the processor is responsible for processing sensing signals; the camera can collect surrounding picture information in real time; and the sensor can monitor the status and movement of objects. The glasses also contain a small, lightweight battery that powers the entire device.
"We also sell it on behalf of others. I've never seen this kind of sensor before. I don't know how it works. Maybe it's through optical detection and then calculation."
"There was a pollution problem here some time ago," Chaoxin said.
Pollutants that may be produced during the production of electronic components include heavy metals, organic solvents, ammonia, etc. These substances can cause pollution to water bodies. Organic solvents: Organic solvents, such as alcohols, ethers, aromatics, etc., are used in the manufacturing process of electronic products. Heavy metals: In the process of manufacturing electronic components, some heavy metal substances are used, such as lead, cadmium, arsenic, etc.
Chaoxin said: "Generally, there will be corresponding treatment. But there have been some problems with the sewage treatment system recently."
Purification equipment is used to treat pollutants, and technologies such as desulfurization, denitrification, dust removal, and organic pollution removal can be used to effectively discharge pollutants to certain safety emission standards. Use resources to treat pollutants, disassemble these pollutants, and use regeneration technology to convert these pollutants into new raw materials or useful products, thereby achieving product recycling.
