After autopilot technology was seen as a turning point in the automotive industry, the discussion of the technology generally stayed on family cars, trains and buses. Recently, a Ford patent reminded people that autopilot can also make traffic police Law enforcement has become more efficient. The patent shows that the self-driving police car can detect excessive speed, illegal parking and other behaviors, so that these work no longer rely on manpower to complete, traffic police can do something that can not be done by automation technology. The self-driving police car can independently detect the violations, and can also find other violations with the help of the surveillance camera. Once the violation is found, the police car will communicate with the illegal vehicle and other vehicles around it to confirm the speed and vehicle status. The police car will capture the license plate, photos and other information of the illegal vehicles and automatically track them. It can also warn speeding vehicles remotely, and even the police car can decide whether to fine it through the AI ​​system or give the driver a serious warning. From the patent map, we can find that this self-driving police car will adopt a 5-door hatchback design, with automatic driving function, equipped with AI system speed detector, high-speed camera and other networked communication equipment. If all the above functions are realized, the self-driving police car can do more work than the manual police. Of course, according to the logic of the past, patrolling law enforcement by autonomously driving police cars and monitoring the driving behavior of human drivers may make it difficult for some people to accept. Although Ford's patent will not be applied to products in the short term, it does not seem to be practical. However, with the further development of technologies such as autonomous driving and wireless communication, the scenes in patents will eventually become the norm in people's lives. Cross flow fans are mainly used for air conditioners, air curtain equipment, dryers, dry-type transformers, household appliances and equipment on grain combine harvesters Cross Flow Cooling Fan,Copper Cross Flow Fan,Transformer Cooling Fan,Top Blowing Series Cooling Fan Henan New Electric Power Co.,Ltd. , https://www.newelectricpower.com
Service conditions of transformer cooling fan:
1. The ambient temperature shall be+75 ℃ ≥ - 40 ℃.
2. The industrial gas passing through the cooling fan is not allowed to have strong acid, strong alkali and various solutions.
3.Sand and dust and other sundries are not allowed to fall into the fan, so as to avoid fan burning and fan blade breakage.
Working principle
When GF series cooling fan is used for dry-type transformer, the fan is placed on both sides of the coil, and the cold air is directly blown into the high and low pressure cooling air passages of the dry-type transformer coil, which has obvious heat dissipation effect, ensuring the normal operation of the dry-type transformer and prolonging its service life. Fan start stop, transformer overtemperature alarm, overtemperature trip and other functions are provided by the temperature control device.
Maintenance and use
1. Before the fan is used, the insulation resistance shall be tested to be greater than 2 megohms. When the fan is hot or humid, the insulation resistance shall not be less than 0.5 megohms.
2. Before starting the fan, please check whether the appearance is intact, whether the connection is reliable, and whether the wind wheel rotates flexibly without blocking.
3. Clean the dust in the fan regularly to prevent affecting the air volume.
