Description

Obstetrical medicine cabinet information interaction method and system based on multimode communication decision Technical Field The invention belongs to the technical field of obstetrical medicine cabinet information interaction, and relates to an obstetrical medicine cabinet information interaction method and system based on multimode communication decisions. Background In medical environments, particularly in high-risk departments such as obstetrics, the reliability and timeliness of data interaction between medical devices and hospital information systems is of paramount importance. The special medicine cabinet of obstetrical department is as the key node of medicine management and clinical execution, needs the real-time record of taking of uploading medicine, receives urgent doctor's advice instruction. The information interaction directly relates to the safety of patients and the smoothness of the treatment process. To ensure continuity of data transmission, such devices typically need to be deployed in areas with stable network coverage to ensure a continuous connection with the server. A commonly employed solution within the current industry for data communication of such medical devices is to utilize a wireless local area network deployed inside the hospital as the primary communication link. Part of the solution to enhance reliability, a cellular mobile network module is additionally integrated as a backup link. In this configuration, the system typically employs active-to-standby switching logic, i.e., the system passively switches to a standby cellular mobile network link for data transmission after the active wlan link is completely broken or the signal quality is below a preset minimum threshold. Such single link operation or simple passive failover mechanisms are currently the more mainstream technology implementations. When the traditional mode is used for processing complex network environment and high-timeliness service demands, the technical problems are that firstly, based on a single link working or passive switching scheme, the judgment dimension of network quality is single, and the judgment dimension is usually only dependent on signal strength, and key indexes which affect transmission quality, such as packet loss rate, network delay and the like, are ignored, so that the system can be maintained on a link with strong signal but poor actual transmission performance. Second, such passive switching mechanisms may cause delays or interruptions in data transmission at the moment of link switching, any delay may be risky for obstetrical emergency rescue instructions. In addition, the existing scheme generally has the same meaning for all service data, fails to provide differentiated transmission guarantee strategies according to the emergency degree of the service, so that non-emergency conventional data compete for the same communication resources with life-critical emergency data, and transmission of key information cannot be guaranteed preferentially when a network is congested.
