The latest home "security" equipment debut allows you to go out
Tapered roller bearings refer to radial thrust rolling bearings with tapered rollers as rolling elements. There are two types: small cone angle and large cone angle. The small cone angle mainly bears the radial and axial combined load based on the radial load, and is often used in pairs, installed in reverse, the inner and outer seat rings can be installed separately, and the radial and axial clearance can be adjusted in installation and use; The large cone angle mainly bears the axial and radial combined load based on the axial load, and is generally not used alone to bear the pure axial load, and can be used to bear the pure radial load when it is used as a pair configuration (the end of the same name is relatively installed). The ability of a single row tapered roller bearing to withstand an axial load depends on the contact angle, i.e. the outer ring raceway angle, the greater the angle, the greater the axial load capacity. The most widely used tapered roller bearing is a single row tapered roller bearing. In the front wheel hub of the car, small double row tapered roller bearings are used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills Tapered Bearings,Bearings 7212,Low Noise Bearings,Tapered Roller Bearing Hebei Fangqiang bearing manufacturing Co., LTD , https://www.fangqiangbearing.com
Automatic tracking of the suspect's instant snapshot of the “Automatic Tracking System†in the exhibition hall was developed by a research institute in Baoji City, our province. The author saw the demo. Assuming that a certain district has an “automatic tracking system for police intelligence†installed, after the 80 households in the community set a target, once someone touches the window frame of a resident, the “Automatic Tracking System†will be within 5 seconds. Lock the target and quickly take pictures of the suspect's face, while passing the information to the public security agency through the Internet. According to reports, in the past, there was a case of household theft in the community. The most troublesome thing for the public security organs was that someone did not know what to do. If the "Automatic Tracking System" is installed, the portraits captured by the system will help the police catch criminal suspects within the shortest possible time. Learned that at present, this set of equipment is in the province of Baoji, a district is trial operation. Provincial Public Security Bureau said that if the anti-burglary effect is good will be promoted in our province. According to reports, the price of this system is about several thousand yuan.
The home security system allows you to go out and relax. The highlights of this exhibition are not only “security†but also “security†into the home. If the “Home Intelligent Terminal†is installed, the residents go out and set the device to “go outâ€. Once the thieves enter the room, infrared light will be detected and an alarm will be issued. The alarm information will be transmitted to the community “security office†at the first time, and the security can be checked upstairs according to the alarm of the household. The user can also download the terminal software on the mobile phone to view the situation at home and anywhere. However, according to reports, such a system has very high requirements for the community hardware and is suitable for use in "digital communities" and some high-grade residential areas. This set of "installed home smart terminal" price is also expensive, about 5,000 yuan. The visiting citizens stated that the equipment is very good, but the requirements for the community are too high and can only be used after living in a high-end community. The reporter learned that the expo will end on the 25th of this month and readers can visit it for free.
