Abstract: Abstract: 【Objective】Urban comprehensive parks are important “prevention areas” of urban disasters due to the nature of their land use and distribution of infrastructure in those spaces. However, traditional disaster prevention and risk avoidance methods have been unable to meet the intricate conditions and requirements of urban construction, introducing the internet of things technology, that can improve disaster prevention and risk management functions, liberate manpower, and achieve efficient management.【Method】This article analyzes the shortcomings of data collection methods in disaster prevention and risk management functions of the comprehensive park, and introduces the internet of things technology in a targeted manner. Two methods were used to attach RFID tags to park disaster prevention facilities and deliver the RFID bracelet to asylum-seekers. Combined with RFID readers, data of park disaster prevention facilities and refugees' activities can be accurately and quickly collected. At the same time, according to the principles of combining park disasters with disasters, the Hongmei Park in Changzhou City was taken as an example. The situation was divided into two situations in peace time and disaster time.【Result】The Hongmei Park was used as an example to read information through readers by inserting RFID tags on park disaster prevention facilities and sending RFID bracelets to asylum-seekers. Accurate and rapid collection of disaster prevention facilities and data on the activities of refugees was accomplished. Additionally, an orderly park ticket management system was established under the internet of things technology, as well as an evacuation data collection system for refugees during disasters, and an intelligent disaster relief material distribution system. Further, disaster prevention facilities, work procedures for evacuation and resettlement of asylum-seekers, and an improved management system for disaster prevention for urban comprehensive parks were developed.【Conclusion】Based on the internet of things technology, the comprehensive park disaster prevention and risk avoidance process can use disaster prevention facilities in a rational and orderly manner, in real-time, accurately grasp the flow of information of refugees, and quickly and easily distribute disaster relief materials to improve management efficiency.
