The highest level of epidemic prevention and control is precise prevention and control. That is to say, through rapid flow adjustment, we can track down all the close contacts and sub-close contacts, and only isolate them without affecting the work and life of others. Of course, it is difficult to achieve absolute precision prevention and control, so how to measure the degree of precision prevention and control in a region with a quantitative method. How to achieve the balance between security, efficiency, and economy under the abnormal background. From the perspective of safety, the prevention and control of the COVID-19 epidemic are still in a critical period. Once it is not carefully controlled, it may still cause secondary transmission, which will bring huge losses to the city's epidemic prevention work and the safety of residents' lives and property. Therefore, in order to immediately feedback on potential infectious sources, we created the fusion of FFR and SWF algorithms to expand the frequency capacity. The supervisors of large business districts can ensure that the frequency is distributed among as many groups as possible through the greater capacity to improve the information inspection mechanism.
