虛擬現實技術在電梯安裝維保培訓中的應用
How VR technology applied to the training of elevator installation and maintenance
(Tony Ma)
10年前我記得湯姆克魯斯演過一部電影叫《少數派報告》，講述的是未來的刑偵機構可以預知刑事犯罪的時間和地點，并在悲劇真正發生前瞬間將被害人救出，并將罪犯繩之以法。在此，故事情節我不想提及，大片隨時都可以去網上看。我只想針對其中辦案人員通過手勢驅動計算機系統的運作從而產生虛擬現實場景，作進一步的展開，還是那句話，我們電梯人只談電梯。
虛擬現實技術也被稱作VR，是Virtual Reality的縮寫，如果您看到的是VRP，那就是Virtual Reality Platform的縮寫，即虛擬現實平臺。目前我國電梯領域的專業軟件公司運用VR技術已經開始在國際電梯安裝維保領域中展露頭角。戴上虛擬現實智能眼鏡，手握控制手柄后你就是一個穿著桔色工作服的虛擬電梯檢修工了。
By wearing virtual reality glasses or helmet, and 2 wireless remote stickers, now you are soon becoming an elevator installer in a world of virtual reality.
通過眼鏡你就會看到虛擬井道安裝場景，控制手柄就是你的手，通過手柄操作可以完成抓取、移動、定位、按壓等動作。如下是轎廂架吊裝安裝的虛擬場景，通過手勢握持動作可以把持吊裝鐵鏈將上梁移動到安裝位置。
Through the glasses you will see the entirely real situation what you’d ever seen in the hoist-way. You can use the stickers as your hands to grab, to move and to press work-pieces until they kept their place in position. Below is about the process of crosshead lifting and mounting.
通過手勢握持動作抓住導靴，系統會自動提示你安裝的位置和在導靴板上的方向定位，如下圖黃色部分所示：
Below is the process of grabbing guide shoes and adjust its direction for correct mounting, which has been high-lightened in yellow.
當然通過系統的智能解析模塊，也可以自動判斷出你身體部位的位置，比如在檢查門機光幕的響應精度過程中，可以在關門時把手放到門縫中，感受門板停住并彈開的反應，系統會自動記錄光幕的響應時間并給調試員做出引導。
By the function of embedded intelligent analysis module, the system will know where your body exactly is. The best example for this is to try extending your hand in the middle of two car door panels as they are closing, and see its sensibility. The module will automatically record the reaction time of light curtain probing the obstacle and bouncing to opposite direction.
培訓模擬不僅可以是單人模式，也可以有多人聯機模式，比如一人在在底坑檢查限速器張緊裝置的同時另一個人檢查電氣開關的安全性是否符合要求。
The training courses can be set to the mode of multiple installers by networking. For example one guy is inspecting tension device of over-speed governor meanwhile allow the other checking the electrical switches in pit.
在具體某個科目的檢修環節中，系統還會自動提供引導人員如何進入，比如轎頂檢修的基本操作，下圖方框中的腳印圖標顯示的是踩踏點，引導如何正確安全進入到轎廂頂部。
During the course of car roof inspection, the system will guide the installer enter by following the footprint marked on the surface of car roof, which means you can step onto it safely.
企業可以根據培訓需求制定針對本企業的培訓科目，帶教老師也可以錄制培訓知識點的具體操作過程，作為企業標準安裝培訓視頻教程，還可以針對學員科目知識點考試結果予以評分，如下圖所示。
The training department of elevator company can figure out detail subjects according to their own requirements. This also allows the trainers to create a series of preliminary correct operation activities with proper sequence as standard and assess students performance when in exam.
