Design and Implementation of Remote Real-time Monitoring System for Large-scale Medical Equipment Based on Log Analysis

目的开发大型医疗设备远程实时监测系统,有效保障设备运行,减少停机时间。方法采用传输和分析隔离设计以保障医院病人信息及检查数据的安全:使用日志采集盒抓取设备日志,经物理隔离后利用4G模块将数据传输到云端服务器存储;然后基于日志分析技术对数据进行模块化解析,并根据建立的阈值及故障优先提醒规则,实现设备状态实时监测。结果系统在10台大型医疗设备上线使用,可实时监测设备关键参数及故障情况,实现工程师第一时间收到设备报警信息和故障代码。同时,还可利用日志提示性信息采集设备扫描数据,以获得设备运行和单机效益报表。结论基于日志分析技术的监测系统有效实现了大型医疗设备实时监控,不仅将响应式维修转变为预见式维护,有效减少设备使用成本;还可以帮助临床实现精细化管理,并为医院科学配置CT/MR等大型设备提供数据支持。

Objective To effectively guarantee the operation of equipment and reduce equipment downtime,a remote real-time monitoring system for large-scale medical equipment was developed.Methods The system adopted transmission and analysis isolation design to ensure the security of patient information and inspection data,log box was used to grab the device log,and after physical isolation,the 4G module was used to transfer the data to the cloud server for storage.Based on log analysis technology,the data was analyzed modularly,and the real-time monitoring of the equipment status was achieved according to the established thresholds and fault priority reminding rules.Results After being used in 10 CT/MRI equipment,the system could monitor the key parameters and fault conditions of the equipment in real time.Once the equipment status was abnormal,the engineer would receive alarm information and fault code in the first place.It could also use the log information to collect the scanning data,so as to obtain the operation information and benefit reports of the equipment.Conclusion The monitoring system based on log analysis technology effectively realizes the real-time monitoring of large-scale medical equipment,transforms the responsive maintenance into predictive maintenance,which effectively reduces equipment use costs.It can also help the clinic to achieve refined management,and provide data support for the hospital to properly configure CT/MR.
