Wuxi Lihai Technology Co., Ltd. is a professional manufacturer of electric vehicle controllers. Founded in February 20001year, the company is mainly engaged in the research and development and manufacture of electric vehicle controllers. At present, the company has a very large-scale production plant.
We have gathered many technical elites, made in-depth research in the field of motor drive, and cooperated with many researchers of Nanjing Panda Electronics for a long time to develop a variety of electric vehicle controllers. The products have high reliability, complete varieties and favorable prices.
Weiyuan International Group (Shanghai) Technology Co., Ltd. was established in May 2004, and in June 2006, a production base of electric vehicle controllers was established in the north of Nantong Railway Station in Jiangsu Province. The production base covers an area of 1.66 million square meters, with a building area of 6,000 square meters, and specializes in the research, development, production, sales and service of core technologies of electric vehicle controllers.
Yueqing Sanyou Electric Appliance Factory is located in Liuzhou, Wenzhou, which is known as the "Capital of Low-voltage Electrical Appliances in China", with beautiful scenery and convenient transportation. The enterprise was established in 1998. Is a manufacturer integrating R&D and electric vehicle parts production, sales and service. Mainly produces DC governors, controllers, DC contactors, electronic handlebars, electronic pedals, chargers and other electric vehicle accessories. The enterprise has patented technology in more than ten countries.
Working principle:
Electromagnetic sucker controller: 380V AC voltage is reduced by transformer and rectified by rectifier, and becomes DC of 1 10V, and then enters the sucker through control device. At this time, the sucker is magnetized, and the reverse voltage line is connected when demagnetizing, and the controller realizes the demagnetization function.
Access controller: The access controller operates in two modes. One is the inspection mode and the other is the recognition mode. In patrol mode, the controller constantly sends query codes to the card reader and receives reply commands from the card reader. This mode will remain until the card reader detects the card.
When the card reader senses the card, the card reader gives different replies to the patrol command of the controller. In this response command, the card reader sends the code data in the proximity card to the access controller, so that the access controller enters the identification mode.
In the identification mode of the access controller, the access controller analyzes the internal code of the induction card and compares it with the card data stored in the device to implement the follow-up actions. After receiving the data, the access controller will send a command to reply to the card reader, so that the card reader can be restored, and at the same time, the access controller will return to the inspection mode.
