基于PLC+4G的病案庫房遠程巡查機器人研發

摘 要：研發一款遠程視頻巡查庫房中病案霉變痕跡、蟲害痕跡及庫房滲水痕跡的機器人。機器人采用四輪行走形式，2個后輪由2臺步進電機分別驅動。機器人上安裝垂直升降絲桿，其滑塊上安裝水平伸縮絲桿，一臺筒形病案檢查攝像機安裝在水平絲桿滑塊上，2根絲桿均由步進電機驅動，另有2臺360°球形攝像機保證機器人行走無盲區。設計用戶手機端HMI，點擊HMI上按鈕，通過物聯網-4G-4G網關數據鏈向機器人上的PLC發出指令，控制機器人把病案檢查攝像機移動到檢查位置。3臺攝像機視頻通過另一條4G-物聯網數據鏈傳到用戶電腦屏幕顯示。實驗驗證遠程控制系統及信號傳輸數據鏈切實可行，可在電腦上遠程視頻察看庫房病案存儲狀況，確保病案安全。

Abstract： A robot for remote inspection of medical records in a warehouse for signs of mold， insect infestation， and water seepage is developed. The robot adopts the form of four-wheel walking， and the two rear wheels are driven by two stepper motors respectively. A vertical lifting screw is installed on the robot， a horizontal telescopic screw is installed on the slider， a barrel-shaped medical record examination camera is installed on the horizontal screw slider， and both screws are driven by stepper motors. another two 360° spherical cameras ensure that the robot walks without blind areas. This paper designs the HMI of the user's mobile phone， and one needs to click the button on the HMI， send instructions to the PLC on the robot through the data link of the Internet of things-4G-4G gateway， and control the robot to move the medical record inspection camera to the inspection position. The videos of the three cameras are transmitted to the user's computer screen through another 4G-Internet of things data link. The experimental results show that the remote control system and signal transmission data chain are feasible， and the storage status of medical records can be viewed remotely on the computer to ensure the safety of medical records.

目前病案有2種形式：紙質病案、無紙化電子病案。多數醫院是2種病案形式并存，即使紙質病案掃描數字化后，也保留紙質病案[1]。依據《醫療機構病歷管理規定》要求，醫院必須保留患者病案30年。一個綜合三甲醫院，年住院病人超過10萬人次，積累病案數量龐大，院區難有足夠庫房，所以常把病案異地存儲或者外包給第三方公司存儲，醫院需定期派人去庫房檢查病案是否霉變及蟲害侵襲，或者庫房是否出現滲水等有害事件，病案存儲管理技術措施有待提高。因此本文擬研發一款遠程視頻巡查病案庫房機器人，可以在醫院辦公室電腦遠程視頻察看庫房內病案存儲完好狀況及庫房狀況。……
