The escalator is the passenger carrying equipment with the highest continuous transportation efficiency between floors of buildings. In the commercial complex with huge pedestrian flow, the escalator has become one of the important carriers to carry and guide the flow of people and maximize the commercial value. In the design of shopping center, escalator design is an important part of moving line design. The ingenious escalator design can enhance the customer experience and effectively attract the passenger flow to the high-rise building.

"Automobile Radar Speedometer" New Regulation Promotion Training Meeting Held
According to the Fujian Provincial Institute of Metrology, a few days ago, the "JJG527-2015 Fixed-vehicle Radar Gun", JJG528-2015 "Mobile Radar Gun" and JJG906 were held by China Quality Inspection Publishing House Education and Training Center. -2015 "Drum counter-type brake test stand" new verification procedures to explain and practical operation demonstration advanced training class" held in Kunming, Yunnan. At the training site, a number of domestic experts trained on the relevant contents of the JJG527-2015 "Radio-vehicle Radar Speedometer" and JJG528-2015 "Radio-vehicle Radar Speedometer", and the speedometer was in the actual verification work. Solve the problem. It is understood that "Radial-velocity fixed-vehicle speedometer" and JJG528-2015 "Radio-vehicle radar speedometer" were formally released in February 2016. Zhejiang Institute of Metrology is the main drafting unit. Radar speedometer is one of the main equipments for traffic management department law enforcement. It is an early batch of products listed in the “Catalogue of Work Measuring Instruments Compulsory Verification of the People’s Republic of China†and the accuracy of its data is crucial. The new rule clearly distinguishes radar speedometers for fixed and mobile motor vehicles, and increases the method of completing on-site speed measurement errors with a normal moving vehicle as the measured object under real traffic flow conditions. In addition, it has also been clarified that the new regulations for radar speedometers for motor vehicles are no longer applicable to the speed-sensing system for motor vehicle geomagnetic coils, and the latter will be tested in accordance with the new Regulation JJG1122-2015 Motorized Induction Coil Speed ​​Measuring System. During this training session, technical personnel and experts conducted technical exchanges and discussions to more fully grasp the new regulations for the verification technology of radar speedometers, which will facilitate the development of future verification work.
