This Lantern design wind turbine is vertical axis with maglev PMG generator, fashion design with many colors, single blade or double blades with quantity 5pcs. It has many advantages: very quiet when moving, never no any noise; star up when very low wind speed; small size so easy to install. However, the power of this one is not very big, from 200W ~ 1000W, efficiency is not good neither, around 15%~35%.
The difference between the laser scanning platform and the scanning gun is that the laser scanning platform can simultaneously emit multiple scanning lines from different directions without manual aiming, and the reading rate of one reading is high. Ordinary laser scanners can only send one scan line, and all the scan lines need to be covered by the barcode to be successfully read. Therefore, retail stores such as large shopping malls, supermarkets and other high-traffic retail stores generally choose laser scanning platform, which can effectively improve the cash register speed and work efficiency of the staff. There are also many brands and models of laser scanning platforms, and their scanning performance is slightly different. Perhaps this is why most users pay attention to scan lines when making comparison purchases.
Most people pay attention to the number of scan lines of the laser scanning platform when purchasing the scanning platform. The more scanning lines, the better the scanning performance. Is this the case? Let's take a look at it with Xiaobian.
The laser scanning platform on the market today is the most common and uses more than 24 lines, but also has a 36-line scanning platform with higher scanning lines. Below we compare these two types of scanning platforms, as follows: 
2, 20 lines: Its light is formed into a flat surface, which can cover most areas or have omissions, which is common in the market.
Through the above comparison, we found that the 24-wire laser scanning platform has an advantage in scanning, but does it mean that the 36-line scanning platform is better than the 24-wire scanning platform? The answer is not necessarily! At present, there are many brands of laser scanning platforms on the market, different configurations and different performances, so it is not easy to compare. The price of the high-preparation scanning platform is relatively high. For some small supermarket users, the ordinary scanning platform can meet the basic scanning requirements, so there is no need to purchase a scanning platform with a higher price, as long as it is based on its own usage. The laser scanning platform for your own use is the best!
