Guo Ziheng (right) and thin Weihan (left) show smart door lock experimental products and supporting mobile APP
The first few days were the opening day of the Xi'an Jiaotong-Liverpool University campus. It coincided with Xipu's independent enrollment. More than ten departments and colleges opened their booths to provide detailed introduction information. Golf clubs, Taekwondo clubs, dance groups and other university associations also showed up. The style has attracted many students and parents who have entered the school to enter the school. Among them, a "smart door lock" designed by Guo Ziheng and others from Xipu's student maker team has attracted the attention of many people. No matter how far you are, just open the mobile phone app and you can "remote" the door switch.
The main creative staff of this product is Guo Ziheng, Shen Tao and junior high school student Xiao Weihan from Xipu. "I am a computer department. In fact, in our profession, students have a lot of self-employment, and most of them are very successful in their business." Guo Ziheng said that it is a coincidence that they are starting a business together. Every summer, Xipu students will follow. The instructor conducted summer research. Last summer, Guo Ziheng's research topic was “Intelligent Securityâ€. Shen Tao's research topic was “User Experience†and Bo Weihan studied “Wireless Protocolâ€. In the product design, three people can be responsible for division of labor. After doing the work, the products were born for half a year.
At present, there are many smart locks on the market, which are smart. In fact, there is not much change in life. Most of them are realized by fingerprints, Bluetooth, etc., and there are distance restrictions. However, in the products designed by Guo Ziheng, the distance will no longer be a problem. "All our design programs are written in a chip. Through the cloud, we can design a supporting APP to transfer instructions to the chip to realize the function of opening and closing the door. No matter how far, as long as there is a network, it can be realized." In Guo Ziheng's hands The chip is only half the size of a palm, but he is still trying to make it smaller. Just plug this chip into any door lock that uses a door card to open the door, you can use this feature designed by Guo Ziheng.
Imagine that when you go out, the family wants to go home but forgets to bring the door card. At this time, you only need to open a special mobile phone APP to open the door remotely. This design makes life more convenient. But in Guo Ziheng's entrepreneurial blueprint, the target customer is not just an ordinary family, his key customer is actually a corporate company. "The biggest difference between our smart lock and the smart lock on the market is that it can build a large security database for the company." Guo Ziheng said that as long as the company installs such a chip on each door lock, then the entry and exit records, room usage It will automatically realize big data statistics in the cloud and analyze the company's more efficient office use plan. This kind of intelligent effect is already very good, but the Guo Ziheng team is still perfecting and optimizing, and designing more intelligent functions for the market. In the future, their biggest goal is to realize all the office in one APP and achieve real intelligence. Office.
Some students are also worried that the door lock is remotely controlled by the mobile phone. Is it not dangerous to lose the mobile phone? In fact, Guo Ziheng said that they are using the latest security protocol, which is based on the patent results of the Oxford University Security Protocol Research Group, which can guarantee the security of the door lock to a certain extent. "If you lose your mobile phone, you can immediately go to our dedicated website and freeze the function on the website."
At present, this smart door lock has realized intelligent functions, and the shape design has not been officially completed yet, but Guo Ziheng introduced that after they participated in the Jiangsu University Student Computer Design Competition, they will immediately register the company in Suzhou and design the product. And mass production. Compared with other similar products on the market ranging from 2 to 7,000 yuan, Guo Ziheng expects this product to be controlled within 1,000 yuan.

Short section is a kind of fittings commonly used in industrial pipeline connection. There are common thread nipples, which are divided into two heads, outer silk, single head outer silk, flat head and outer silk, and some short joints with flanges.
The short section is divided into tubing short section and casing short section. The flanging short section in the pipe fittings is popular with the flange. The flange is set in the flanges, then the tail and the steel pipe are welded. At this time, the flange can be moved. As long as the flange is connected to the flange at any time, the flange can be connected.
The tubing short section is a short tubing. Compared with the tubing, it is only of different lengths and the others are the same. The lengths are: 0.25m, 0.5m, 1M, 1.5m, etc., which are used to match the downhole string.
