1 Introduction With the development of urban economy and scale, various types of roads are getting longer and longer, the number of motor vehicles is increasing rapidly, and the traffic flow at night is getting larger and larger. The quality of road lighting directly affects traffic safety and urban development. How to improve road lighting quality, reduce energy consumption, and achieve green lighting has become a key issue in urban lighting. The primary task of road lighting is to provide safe and comfortable lighting brightness on the basis of saving public energy, to reduce traffic accidents and improve transportation efficiency. Due to the limitations of infrastructure conditions, there is a general lack of communication links for streetlights. The streetlight control method generally only controls the entire road and cannot measure and control each lamp. Based on the Internet of Things, this paper designs an embedded wireless street lamp control module, which realizes the wireless autonomous network of each street lamp, so that each street lamp can be telemetry and remote control, and some units in the street lamp facility (such as electronic ballast) Connected to achieve the brightness (or illuminance) of the street lamp in 30% ~ 100% steplessly adjustable, in the case of ensuring road lighting quality, improved identification and visual comfort, save energy 20 ~ according to ambient light intensity and time period 30%. 2 system structure
The single groove blanking process of motor blanking is a kind of blanking process relative to double blanking. Motor fixed, Rotor Core punching using single groove punching process, its mold design, manufacturing are relatively simple, suitable for small batch, variety of production, has the characteristics of low cost, fast change. With the development of advanced punching machine, production efficiency continues to improve, the single punching process is also developing rapidly. For the large motor, because of the cost of the duplex die and the equipment capacity, the single groove is also used. Another advantage of single groove punching is the consistency of groove size. Compound die is the same punch, stator or rotor groove completed at one time. How many slots correspond to the same number of punches, punch size to achieve complete has always been some difficulties: single slot punching is by the same punch to complete all the slots, groove consistency is better.

Stator and rotor laminations are an important part of motors and generators. For large-size and small-batch punching sheets, we usually use the notching method to produce them. The advantages of notching are that the cost of the notching die is low and the production cycle of the notching die is short. It is suitable for producing large size laminations, usually the outer diameter is from 500mm-1250mm. The slot size is more accurate than Laser Cutting.
