Description

Multi-dimensional data fusion-based double-old community aging service coordination method and system Technical Field The invention relates to the technical field of intelligent endowment, in particular to a method and a system for coordinating aging-suitable services of a double-aged community based on multidimensional data fusion. Background Currently, the senior services of the dual-aged communities (i.e., communities with aggregated and aged infrastructure) in China face serious challenges. According to statistics data of civil administration, the population of old people over 60 years old in China breaks through 3 hundred million, wherein the proportion of solitary old people and empty nest old people exceeds 50%, and the contradiction between the supply and demand of the old service of the double old communities is increasingly prominent. In the prior art, some intelligent pension platforms exist, for example, patent CN202310215678.9 discloses a community pension service system based on a cloud platform, which can realize service calling and dispatching, and patent CN202211387965.3 proposes a pension service monitoring system combined with the internet of things, which can collect health data of old people and perform early warning. However, such systems suffer from the following technical drawbacks: 1. The system has the advantages that the data dimension is single, the acquisition precision is insufficient, the existing system mainly depends on active calling of users or single type of sensor data, comprehensive and passive sensing data on physical space states of communities, running conditions of facilities and service capability of multiple main bodies is lacking, the data acquisition lacks layering strategies, the high-risk area and the common area adopt unified acquisition frequencies, so that key information is missed to acquire or redundant data is excessive, meanwhile, the system for data pretreatment is imperfect, abnormal value and missing value processing modes are simple, and the data quality is affected. 2. The evaluation model lacks scientificity and suitability, wherein a scientific multidimensional evaluation algorithm is not embedded in the existing system, decision is made only through simple threshold judgment or subjective evaluation, the cooperativity and the health degree of the whole service system cannot be quantitatively evaluated, and although part of the system adopts an entropy weight method or a coupling coordination degree model, the related interference among indexes and the scale difference of different communities are not considered, so that the weight calculation deviation is larger, the coordination degree evaluation result lacks pertinence, a manager still needs to make decision by experience, and resource allocation is blind and low in efficiency. 3. The fuzzy language evaluation system is imperfect, for subjective data such as the satisfaction of the old, the existing system mostly adopts a simple secondary evaluation standard, the evaluation dimension and the time span are not distinguished, the method for converting the language evaluation into the numerical value is coarse, and the theoretical support is lacked, so that the reliability of the quantification result of the subjective data is low, and the actual quality of service cannot be accurately reflected. 4. The feedback mechanism is lagged, the optimized path is inaccurate, the existing system only responds after the problem occurs, the active intervention capability based on data prediction and evaluation is lacking, the optimized path is generated by depending on a single target (such as lowest cost), multi-target balance such as coordination degree improvement and service response speed is not considered, the path content is general, details, resource investment and effect prediction are not explicitly implemented, the operability is poor, and accurate optimization for treating the disease cannot be realized. Therefore, an integrated technical solution capable of realizing precise multi-source data collection, scientific multi-dimensional evaluation, refined quantization of subjective data and multi-objective dynamic optimization is urgently needed in the field, so that the precision and efficiency of pension resource allocation are fundamentally improved. Disclosure of Invention In view of the above, the invention aims to provide a method and a system for coordinating the aging service of double old communities based on multidimensional data fusion, which solve the problem of resource mismatch caused by data splitting and evaluation deficiency in the existing intelligent aging system and realize accurate, efficient and fair configuration of the aging service.
