Riding the wind of rebirth

Chapter 1659 There is electricity

But since the owner is not afraid, there is no need for him to remind him not to do his own business. The current cost of a household photovoltaic power station in the island country is 60,000 yuan per kilowatt. The domestic equipment cost is higher, but the labor cost can be almost ignored, so it is similar to that of the island country.

Three kilowatts is 180,000 yuan, plus a series of additional charges such as shipping and installation labor, this small photovoltaic power station cost a total of 200,000 yuan.

For anyone in Lianhe Township, this is an astronomical figure, but in Zhou Zhi's eyes, this thing is only the price of a Santana 2000, which is as cost-effective as it can be.

There is strength in numbers. Although spring ploughing is imminent, the spring ploughing in Lianhe Township is different from that in Jiachuan. It does not take too many people to bury potatoes on the hillside, so a lot of labor can still be freed up to help "build the roof tiles."

In the minds of many Yi people, installing photovoltaic cells on the roof of a grain station is similar to putting up roof tiles. In just a few days, a small 3,000-watt photovoltaic power station was built.

The first thing Zhou Zhi did was to install electric lights in the children's classroom, and also connected the power to the street lamp at the door.

The abundant electricity, unlike the insufficient voltage lines in the countryside, made the entrance of the grain station bright, so that everyone gathered here automatically in the evening to chat, and even played the lusheng, danced the duhe, and danced the pizhen, which was a bit like the square dance in the city in ten or twenty years.

Most ethnic minorities are good at singing and dancing, and this is an example.

However, Zhou Zhi had little chance to participate as he was busy debugging the satellite relay. In addition to the satellite phone, the laptop he brought could finally connect to the Clover Company in Shudu through the satellite relay, forming a true "satellite network link."

In May of the previous year, the Ministry of Posts and Telecommunications introduced IDR equipment from Canada's Spar Company to upgrade and build new satellite ground stations across the country.

As a result, domestic satellite communications began to turn to IDR technology.

IDR service is a new type of data communication service that has been put into use since the mid-1980s. Compared with the traditional FDM/FM, it is a digital system upgrade of time division multiplexing plus frequency division multiple access. It is used in combination with digital circuit multiplication equipment to increase the satellite dedicated line transmission capacity to five times the original.

The maximum information rate can reach 8.448M per second, which is equivalent to transmitting voice channels at the same time.

Of course, this technology alone is not enough, it also requires the cooperation of another invention, that is, the famous VSAT.

VSAT, the full name is Very Small Aperture Terminal, which means very small aperture terminal.

However, please note that although VSAT is called a terminal, it is actually not just a terminal, but a system.

A complete VSAT system consists of a transponder on a communication satellite, a large-aperture hub station on the ground, and numerous small-aperture stations.

Zhouzhi only needs to worry about the small station. How small is the so-called "very small aperture"? Including the antenna, it is only 0.3 to 2.4 meters, which is very light.

Zhou Zhi only needed guards to easily pull it to Lianhe Township.

In addition to being lightweight, VSAT also features flexible networking, low cost, multiple applications, and simple installation and operation, which is very conducive to the popularization of satellite communications. As early as 1, China introduced foreign communication equipment from the former China Communications Broadcasting Satellite Corporation and built the first VSAT communication network in my country. It includes 35 main station and terminal stations, providing satellite communication services for eight industry departments including various national ministries, the Earthquake Bureau, the Ocean Bureau, the Civil Aviation Administration, the Customs, the Economic Information Center, and major banks.

Later, the country began to build wireless paging networks, securities information broadcasting, village-to-village/household-to-household projects, and many ocean-going ship communications, aircraft communications, corporate and government private networks all adopted VSAT.

This time, Zhouzhi also rented an 8M line in the name of Clover Company. As long as it is not transmitting high-definition pictures and videos, but only transmitting Microsoft OFFICE documents, it is completely sufficient.

With this, Zhou Zhi can even go to the Clover Forum at night to find people to play double buckle with.

With this system, plus the online office software developed by Clover, Zhou Zhi can participate in the company's conference calls remotely, review and approve documents in the system, complete daily work, and pay attention to the research and development progress of various projects of the company.

You can even enter the computing center to conduct academic research, follow up, and even write programs yourself without any delay.

Several digital libraries have not yet been opened to the public, but there are already quite a few scanned and archived books inside. There are also many sections of the Clover Forum, and enthusiastic students have uploaded a lot of information, novels, poems, and essays. Zhou Zhi even served as the moderator of two sections, namely couplets and classical poetry.

Although the campus network is now still limited to the information rooms of the several original colleges that make up Shu University, and students can only access the content of the campus network by going to the computer rooms, the enthusiasm and creativity shown by everyone has surprised many people.

The school even collected some excellent poems and articles from the forum and published them in the school magazine. There were also some "great gods" on the forum whose real names were known only by their online nicknames, and who had very high levels of attainment in many fields.

These are all off-topic. What no one could have imagined was that the first civilian satellite Internet application in the southwest region was quietly launched in the remote Lianhe Township.

With sufficient electricity, the many devices Zhou Zhi brought could be charged, and many of Lao Chi Ri’s ancient songs, prayers, sutra interpretations, dances, and rituals could be recorded.

After watching the several large boxes of audio and video tapes brought by Zhou Zhi, Lao Chi Ri also began to believe that what the kid said might come true. The two of them worked together to develop a cataloging and indexing method, classifying the Yi intangible cultural heritage to be recorded into several major categories, including literature, music, dance, fine arts, skills, medicine, folklore, and divination.

Each major category is divided into many subcategories. For example, literature can be divided into legends, history, poetry, proverbs, folk tales, philosophy, classic interpretations and many other subcategories.

Because the audio and video recordings are in sequence, an index booklet is also needed to record the numbered audio tapes and the title, time, introduction, interviewer, interviewee, identity background, address and other information of each recording in sequence.

This actually falls within the scope of field research report production, except that this time the field survey includes not only paper and pen, but also sound and image recording, which can be considered "multimedia."

Old Chi Ri didn't know that his starting point was so high, but seeing that Zhou Zhi was so concerned about the cultural heritage of his tribe, he became more serious.

As the great Bimo of the Yi nationality, Lao Chiri has a lot of books in his private collection, many of which have been covered in dust and have not seen the light of day for a long time. Now with bright lights, he can also sort out the books in his room.

Tu Liangzhi also secretly told Zhou Zhi that old Chi Ri had carried many parchment books and yellow paper scriptures to the mountains and sealed them in a "stone chamber" that only he knew about. Over the years, no one had been able to get any information out of him.

Zhou Zhi might not be able to get anything out of Old Chi Ri, but at least from the current perspective, he is the most likely one.
