that investors and advertisers benefit both parties. After careful analysis of the survey to discuss, we agreed that the product has broad market prospects, After the preparatory work Let's get the job done. Company R & D departments of its technical backbone to proceed with research and development of China's first rolling bollards Traditional light boxes based on the appearance of appearance and the frame structure, R & D focus is on how we screen in accordance with the idea of rolling up, This naturally thought of the use of motor driven roller method, The next problem is how to control screen stagnation and continued after a pause rotation? Ask experts for advice and information you collect related products, and strive to finally return sensor is the best control switching devices, the core part of the solution, then the work is a step-by-step in accordance with the initial design Production of the start of the program, China's first rolling picture of the Divine electronic bollards was born.
