Qi Lianshan followed Liang Yuan into the side door of the device room, which is the same as the chip and gas turbine room, and also uses a large area of transparent dome, and the sunlight is sprinkled from the special glass of the ceiling of the real room, shining on the light green dust-proof floor of the workshop, scattering verdant reflections, giving people the illusion of stepping on the grass.

Liang Yuan took out another card from his coat pocket and inserted it into a card slot by the door, accompanied by a low "buzzing sound", several rows of high-voltage lights hanging on the load-bearing structure of the roof lit up and suddenly became delicate.

Qi Lianshan looked at the card inserted in the card slot and asked curiously, "Did you use this to open the door just now?"

Liang Yuan stretched out his hand and took out the card that opened the door from his coat pocket and handed it to Qi Lianshan, saying, "It's different, the door is light blue, and the power supply is light red." ”

Qi Lianshan took the light blue card, rolled it in his hand a few times, and compared with the light red card inserted in the card slot on the wall, Qi Lianshan realized that the thickness of the light blue card can be about four or five millimeters, far thicker than the light red card

"Xiaoyuan, the thickness of these two cards is different," Qi Lianshan asked.

"Hehe, does Lao Qi have two cards in different ways? Liang Yuan said.

Qi Lianshan pondered for a moment before remembering that when Liang Yuan entered the door, the card and the induction device embedded in the door did not contact at all, but he shook the door lock and opened it in response.

Qi Lianshan pointed to the light red card inserted in the card slot and said, "One doesn't need to touch the sensor." One has to be in contact with the sensor. ”

"Lao Qi is still observing very carefully. Liang Yuan said: "The light blue color is a new technology called radio frequency identification made by the chip room. The light red card is a popular IC card abroad. ”

Radio frequency identification technology originated in the thirties of the twentieth century, with the aircraft as a new type of war tool put into use, how to distinguish friend from foe in the sky has become a problem, the British Empire, the world's largest power at that time, created a device similar to an electronic tag on the aircraft, when the electromagnetic wave of the special frequency band is scanned, the aircraft labeled will reflect back the corresponding signal, and there is no signal feedback without labeling, so that the friend and foe are simply distinguished.

With the advancement of science and technology, the theory of radio frequency identification has gradually improved, and devices have become more and more miniaturized. By the end of the 80s, the world's mainstream manufacturers had been able to integrate the emission and reception of radio frequency waves into small chips.

Nanhu Science and Technology Park did this, at the beginning, to display the locomotive signal on the nose of the locomotive, to solve the problem of poor lookout conditions for drivers and passengers. Accurately identify the problem with the signal displayed by the signal.

When Liang Yuan intervened in the cooperation with Shengjing Signal Factory and developed the 1TCS system, the transponder beside the track became the core of the whole system, so the radio frequency technology as the core of the transponder became the top priority, Wang Xin took the science and technology park after a patchwork, a research team of about 50 people, only half a month to use** The separation device simulates most of the functions of the RF chip and the receiving chip, but unfortunately due to the low overall integration of the circuit, the light blue card thickness mark with the receiving chip embedded in Liang Yuan's hand is made.

"Lao Qi, the light blue card is actually a signal response device. It can convert the electromagnetic waves from the radio frequency emission device into current, and after internal calculation, it becomes a group of special electromagnetic waves and sends it back, and matches the emission device. ”

"Xiaoyuan, can this light blue card and the light red card on the wall be integrated together in the future?" Qi Lianshan asked.

"Recently, the chip room is working hard to improve the integration of various parts of the card, and improve the anti-interference ability of the whole system, and there is no energy to integrate these two things together for the time being, does Lao Qi have any new ideas?" Liang Yuan said with a smile.

"This thing is very similar to the magnetic card type key card I encountered when I was staying in a hotel in Hong Kong," Qi Lianshan said with a little regret: "The first thing I saw just now came to mind the Shangri-La Hotel in preparation, and replaced the key with a card." Guests can enter the room with a light flick like you just now, what a modern thing in China, the grade of the hotel can be improved by at least half a level, and the card can be pulled out directly when checking out, which is equivalent to the automatic power off of the room. It will also save a lot of unnecessary expenses for hotel operations. ”

After listening to Qi Lianshan, Liang Yuan nodded secretly in his heart. It seems that after Qi Lianshan knew that he was in charge of the water park and hotel project, he had put a lot of effort into it recently, otherwise he would not have seen the application value of this system so quickly.

"Lao Qi, you are much stronger than Lao Su, I asked him to do this system some time ago, and he was reluctant" Liang Yuan said with a smile.

Compared with the single-chip microcomputer, the light blue card in Liang Yuan's hand is much simpler, generally speaking, the IC card of the eighties, in fact, is to take out the memory of the single-chip microcomputer directly for separate application, for Su Liangyu, this thing is not difficult at all, but the memory of the HT68O single-chip microcomputer is taken out separately, and the peripheral circuit is equipped to make it possible** Although it is impossible to manufacture on a large scale due to the limited conditions, it is relatively easy to prepare a few hundred with real room equipment.

In Liang Yuan's view, the core chip of IC card is absolutely not to let go, after a few years, the domestic use in this area is calculated in the scale of one billion two billion, the most difficult thing for scientific research is not to know where the results are used, whether they can be accepted by the market after large-scale promotion, in terms of the actual conversion rate of scientific research results, there are one or two out of ten pieces that can be converted into real money, and the rest are basically waste materials, and for Liang Yuan, there is no waste of scientific research at all.

The two laughed and came to a compartment made of colored steel in the corner, Liang Yuan pointed to a beige cabinet in the corner of the wall and said to Qi Lianshan: "Old Qi, you are also engaged in construction, look at the cabinet in the corner." ”

Qi Lianshan looked at Liang Yuan's fingers, there were several rectangular beige cabinets standing in the corners, I couldn't see what the material was due to the paint, and there were three narrow ** small windows installed near the upper edge of the cabinet, and there were two rows of circular indicator lights neatly arranged under the small windows, red and green.

Qi Lianshan walked to the front of one of the cabinets, looked through the small window, and then reached out to open the cabinet door, two large rows of milky white circuit breakers were neatly installed in the middle and lower parts of the cabinet, red, green, and yellow wires were threaded out of the circuit breakers, and finally converged into three thick flat wires across the cabinet and into the wall.

"Xiaoyuan, this thing should be a low-voltage distribution cabinet. Qi Lianshan carefully looked at the structure of the distribution cabinet, then looked up at the bright lamp group on the dome, and said affirmatively: "It is the lighting distribution cabinet in this workshop, and each lamp group is equipped with a separate set of circuit breakers, which is really luxurious." ”

"Lao Qi will look at something else. Liang Yuan said with a smile.

Hearing this, Qi Lianshan stretched out his hand to open the cabinet door next to the lighting distribution cabinet.

"Capacitance compensation cabinet, frequency conversion control cabinet...... , Xiaoyuan, are these all the new things you told me, the real yàn room" Qi Lianshan looked at the thyristors, circuit breakers, AC contactors and other equipment in the cabinet and asked in surprise.

"How can it, the thyristor is purchased, the circuit breaker is its own, the AC contactor is still being studied, and it can become its own later. Liang Yuan said.

"I can't think of it, I can't think of it. Qi Lianshan repeated two sentences in a row.

In the early eighties, complete sets of foreign high-voltage and low-voltage electrical equipment began to enter China, for the Chinese electrical engineers who were still fiddling with fuses and switches, there was no difference between Liu and Grandma Liu's entry into the Grand View Garden, because low-voltage electrical equipment is usually driven by final loads such as various lighting and motors, and the components are complex and easy to damage, for electrical maintenance personnel, every time they find faults, replacement and maintenance is a very cumbersome work.

What's more, if the number of work required for the new and old equipment is not the same after the equipment is replaced, then the entire power distribution system has to be rebuilt.

When foreign electrical predators such as Siemens, ABB with a variety of electrical cabinets in a modular, complete set of professional image appeared in front of domestic users, the introduction of maintenance-free cabinets and relatively free functional modules to replace at will, the vibration caused in the circle of electrical engineers can be imagined.

With the smooth passage of Siemens and ABB in China, the state-owned electrical components and complete sets of electrical equipment manufacturers have collapsed across the board, which is unbearable.

In the first year, the Ministry of Water and Power of the country can not bear to integrate more than 30 large and medium-sized state-owned electrical equipment manufacturers together, the establishment of Wusong People's Electric Company, after the optimization of the combination of group heating, domestic low-voltage electrical equipment manufacturers can be regarded as a sigh of relief.

"Among other things, millions can be saved on electrical equipment just by the project at hand. Qi Lianshan said affirmatively.

Generally speaking, the cost of power distribution facilities accounts for about 5% to 1o% of the total cost of the project, and the 200 million yuan project in the hands of Qilianshan will invest at least 10 million yuan in power distribution facilities.

"Lao Qi, you have confidence in me, and you didn't even ask about the breaking ability of the circuit breaker, so you plan to use it directly in the project. Liang Yuan said with a smile.

Qi Lianshan laughed and said: "When did Xiaoyuan get the garbage goods, according to your temperament, you can take it out and see, it must be about to be produced on a large scale, and it is planned to be introduced to the China Construction Third Bureau for use, and the number of jù will definitely be better than the same products in China." ”

"Besides, this cabinet is no different from Siemens and Bofary's electrical cabinets in terms of appearance and structure, and the empty drawers should be used to replace functional devices. Qi Lianshan said.

Liang Yuan nodded and said with a smile: "One thing, Lao Qi, you guessed wrong, now this set of things has no mass production capacity at all, I'm worried about where to find equipment."

ps: The power outage continues today, all day, and the night will not come yet, and the building is full of running to the Internet café code, and it has been confirmed that the transformer in the community is broken......)
