Qi Yanliang still remembered that Dai Zhao's expectation for them was to bring these construction vehicles to new cities, build new cities, and build new lives. The kind of spirit that is not afraid of hardships, strives to overcome difficulties, and fights to the end, the fearless, optimistic and positive spirit, the kind of arrogance that pioneers the world. He wanted to pass on this spirit to Ying Yang.
Yonghan still remembers that when Yan Zhuoshou was building a new transmission and distribution site, he was very enthusiastic about it. At that time, the entire relocation and reconstruction of the transmission and distribution stations was also a very huge project. In the summer, I still wear a helmet, and my head is covered with sweat. In winter, you still have to stand outside, braving the cold.
Everything they do, every hardship and hardship they experience, is to enable the next generation to have better living and working conditions.
"We will always be behind you to support you. However, no matter what difficulties and challenges we encounter, never forget our original intention. That is the source of strength." He gently patted Yonghan's shoulders with his calloused hands. .
He was thinking, what would he say to this young man if he saw Li Rong again? On the one hand, he believes that the new generation should do things more smoothly and achieve greater achievements than he did. They are also very serious and can complete tasks one by one. But at the same time, he is also worried about whether the next generation will have enough resilience and perseverance. Can they distinguish between friends and enemies? But maybe after this era has passed, there will no longer be the same kind of suffering.
Tengcheng's Water Conservancy Engineering Institute is still discussing how to solve the flooding problem. This requires a comprehensive approach that includes reducing the ability of stormwater to flow into rivers, strengthening the drainage capacity of rivers, and strengthening the protection of flooded areas. Set up rainwater collection devices to reduce the amount of rainwater flowing into rivers or sewers. Enhance the drainage capacity of river channels, including some methods of clearing river channels, widening river channels and raising river edges. Build dams or fixed barriers in flooded areas to reduce flooded areas. Reduce urban construction, especially near rivers, to reduce the number of buildings that block water flow.
Tengju Automation Company cooperated with the Institute of Water Conservancy Engineering to make some auxiliary measurement devices. For example, detect river flow, temperature, and water level.
Lirong is installing some solar installations to power the measuring devices. There is also a function to automatically face the sun.
Automatic sun-facing harvesting devices hope to maximize the use of solar energy and track the movement of the sun.
Solar panels are the heart of the device and are used to convert sunlight into electricity. It consists of multiple solar cells that convert photons from sunlight into electrons. The working principle of solar cells is based on the photovoltaic effect, which converts light energy directly into electrical energy. When sunlight shines on a semiconductor p-
When connected, new hole-electron pairs are formed. in p-
Under the action of junction electric field, holes are generated by
area flows to the p area, and electrons flow from the p area to
area, a current is formed when the circuit is turned on.
This is a device that directly converts sunlight energy into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode converts the sun's light energy into electrical energy and generates current. When many batteries are connected in series or parallel, it can become a solar cell array with relatively large output power.
To ensure that the solar panels are always facing the sun, the installation is equipped with a tracking system. This system automatically adjusts the angle and direction of the solar panels based on the position and movement of the sun. It uses sensors and electric motors to achieve automatic tracking.
The control system is responsible for monitoring the position and movement of the sun and controlling the operation of the tracking system. It can calculate the optimal solar energy collection angle based on preset algorithms and parameters, and automatically face the sun by controlling the movement of the tracking system.
To continue supplying power at night or on cloudy days, the unit is also equipped with an energy storage system such as a battery pack or supercapacitor. These energy storage devices can store solar energy collected during the day for subsequent use.
The advantage of the solar energy collection device that automatically faces the sun is that it can maximize the use of solar energy resources and improve energy utilization efficiency.
"You know how to make a lot of things." Xinyuan came from behind and said.
Li Rong said: "If you know a little bit about everything, life will be more exciting."
Xinyuan said: "This sentence sounds very familiar."
Li Rong said: "That must be said by people who are professional in measurement, control and automation."
Robots, sun tracking devices, river sensors, power detection devices, map position display devices. Xinyuan counted them one by one.
Xinyuan said: "Are you free tonight?"
Li Rong said: "Yes. But I think there is still a lot to do."
Xinyuan said: "You don't have to wait until everything is done before you think about yourself."
Li Rong said: "Yes, thank you."
Xinyuan said: "I always want to wait until a lot of things are done, then I can rest. But the work is never finished."
Li Rong said: "I'm sorry, I'm too busy at the front. I never bother to contact you. Some people's careers are like building a building, and some people's careers are like building a city."
Xinyuan said: "Does that mean I have to wait for you for a long time?"
Li Rong said: "When it is finished, it will be very magnificent."
"Last time Jiang Sheng and I went to an office building to deliver electromagnetic sensors to a company. But the electromagnetic sensors they ordered were too powerful. They might be detecting things at long distances."
Xinyuan said: "Is there anything that needs to be tested here?"
"It's very far away. Maybe it's detecting the ground? Leave him alone."
Xinyuan said: "Why did you come to Tengcheng?"
"I'll watch Tenghe with you." Li Rong said this because he felt that he was with the person he liked.
Xinyuan smiled and said, "Is it so romantic? It sounds like you want to accompany me to watch the sea."
"This thing isn't working now, I need to see what's wrong."
The output voltage of a single photovoltaic cell is very small, and some transistors amplify the signal of the original photovoltaic cell. A triode is a semiconductor component consisting of a base, emitter and collector. When a forward bias is applied between the base and emitter, current flows from the emitter to the collector. The magnitude of this current can be adjusted by the base current, so the triode can be used as a current amplifier.
