The research and development of new drugs, close contact and traceability, auxiliary diagnosis and treatment are all inseparable from the participation of scientific and technological enterprises. Let's talk about big data, which plays an important role in epidemic situation judgment, transmission path analysis, accurate prevention and control and subsequent treatment, effectively improving the pertinence and efficiency of prevention and control. Since the outbreak of the epidemic, many enterprises have actively participated in it, such as Elliott, Tencent and Huawei in Shenzhen. Among them, Elliott's N+1 digital sentry solution has been deployed and applied in epidemic prevention units in Shanghai, Beijing, Shenzhen and other places, and the epidemic prevention wisdom front has been built by scientific and technological means.

this solution covers a variety of AI epidemic prevention equipment, including digital sentry P81 and handheld digital sentry BM5311. Taking BM5311 as an example, it looks like a smart phone, supports voice broadcasting, 4G full netcom, WiFi and Bluetooth 4.1 networking, and is suitable for various mobile epidemic prevention scenes such as high-speed intersections and grid workers' door-to-door verification.
