With the "east wind" of digital transformation, China's pharmaceutical industry has entered the "fast lane" of green, digital and intelligent development. A series of digital technologies, such as artificial intelligence, have gone deep into all aspects of the development of the pharmaceutical industry, enabling pharmaceutical enterprises to upgrade their manufacturing capacity system and continuously improve their business efficiency. For pharmaceutical enterprises, digital production has become an important part of the entire industrial chain, and wireless network deployment plays a key role in the production scenario. According to Lei Chunming, solution director of Ruijie Network Enterprise Industry Department, in the process of upgrading intelligent manufacturing, the clean workshop needs an intelligent network to lay the underlying data base. Recently, for the production scenario of the pharmaceutical industry, Ruijie Network released a wireless solution for the clean workshop of pharmaceutical enterprises. This solution has four features: "simple deployment, fast compliance", "uninterrupted mobile production", "real-time wireless data acquisition", and "wireless dynamic security defense", thus helping pharmaceutical enterprises speed up the digital transformation of their production networks. The four characteristics enable the digital transformation of pharmaceutical enterprises. Specifically, in terms of network deployment, the "industrial oriented AP" and "minimalist Ethernet" based on Ruijie Network can ensure the rapid, compliant and minimalist deployment of the clean workshop network of pharmaceutical enterprises. According to Lei Chunming, solution director of Ruijie Network Enterprise Industry Department, the penetration signal strength of industrial directional AP color steel plate is up to - 45dBm. By deploying one set on the interlayer above the color steel plate in each clean room, it can avoid punching, threading, threading and sealing the color steel plate in the old workshop, so as to ensure that the production line does not stop production. At the same time, there is no need for re certification of cleanliness. The comprehensive cost is low, and the business goes online quickly. In the BCD level clean area of the new workshop, the scheme adopts ceiling AP (acrylic cover+seal) to achieve rapid network deployment in the clean area. In addition, the application of Ruijie Minimal Ethernet technology, including Ethernet host and Ethernet AP, in this scheme can achieve 1/5/10Gbps high AP performance and lower failure rate while saving weak current room. In terms of wireless roaming, based on AI Radio of Ruijie AR series APs, the wireless solution of pharmaceutical enterprises' clean workshop can actively detect the terminal signal, select the best AP to guide the terminal wireless roaming, with an average delay of less than 30ms, an overall packet loss rate of less than 0.5% and no continuous packet loss, so as to achieve zero roaming in the industry. "Through 'zero' packet loss wireless fast roaming, business non sensing experience and MES operation, this solution can ensure the continuous mobile production of pharmaceutical enterprises." Lei Chunming said. In terms of time delay, the scheme adopts Ruijie industrial wireless gateway, whose overall packet loss rate is less than or equal to one ten thousandth, and the average time delay is less than or equal to 10ms. In addition, it adopts the anti-interference and highly reliable 2.4G+5G dual RF link aggregation technology to support serial/network port to wireless, so as to realize stable and reliable real-time collection of wireless data. At the same time, the wireless solution for the clean workshop of pharmaceutical enterprises also realizes dynamic intelligent prediction of wireless security risks and active defense, as well as visual wireless intelligent diagnosis and network optimization operation and maintenance through collaboration with the cloud of the Ruijie WIS cloud management platform. The data released by Ruijie Network shows that through this scheme, the operation and maintenance efficiency of drug enterprise administrators has been greatly improved, and the fault location time has changed from 3
