途虎养车的APP线上预约
传统的汽车维修过程是车主把车放到维修店里面，等修好了等通知取车，而整个修车的过程，车主都是看不到的。所以这片空白的时间段就可能会使得某些纠纷产生。比如，车主觉得有些零配件不必要更换，但是师傅换了；或者感觉某些地方安装不到位，不规范，所以不满意，诸如此类的。这些看似琐碎的小事，其实都可能会影响到客户的体验，从而导致他们可能会把汽修店拉进黑名单。为了令修车的过程更加透明，途虎养车给出了一个更好的方案。 众所周知，通过途虎养车修车非常方便，车主可以直接使用途虎养车的APP线上预约，然后到就近的门店维修，在这之前，关于车辆的问题以及需要更换的零配件及报价等相关的琐碎都已经明了，在客户同意的前提之下，途虎养车的师傅才上手，这样也可以更好的避免纠纷的产生，也能免除双方扯皮。 当然，最妙的还不是这一点，最妙的是在整个修车的过程，车主都可以通过手机APP全程观看。 据悉，途虎养车工场店的工位摄像头全面开放，用户拿着自己的手机就可以“无死角”观看技师施工过程。 途虎养车的师傅全部经过专业的培训上岗，因此他们的操作都是非常严谨的，所使用的工具也是专业的，哪怕是一些小细节，小动作也做到十足规范。 例如工具一定会放到工具车上面，而不会乱放。轮胎装卸的十字扳手始终放在1米范围内；卸下的小螺丝一定会放进收纳盒；施工完成后的两轮质检中，技师用扭力扳手检查轮胎时必须每颗螺丝拧到“咔咔”两声；另外，自检完成后还会有非施工人员以单个轮毂为施工项目执行互检。 所有的这些，手机那一端的车主都可以看得一清二楚，一个细小的操作都尽在眼中，所以完全没有维修空白，让车主看得清清楚楚，明明白白。 因此很多车主都愿意把车放到途虎养车的门店里面进行维修，因为他们对维修过程的大小事都了如指掌。试问这样一种维修保养方案，谁不会称心？ 途虎 途虎养车 途虎养车APP
How to distinguish the wavelength by the color of the pull ring of the optical module?
In order to distinguish their optical modules,different manufacturers can distinguish them by their wavelength,transmission distance,package,etc.do you know any other methods? Commonly used optical modules have four wavelengths,850nm,1310nm,1490nm and 1550nm.Among them,the pull ring color of the Gigabit SFP optical module 850nm is black,the pull ring color of 1310nm is blue,and the…
How to eliminate and solve the fault of optical transceiver?
The use of optical fiber transceivers is very simple.When the optical fiber transceivers are applied to the network,if they cannot work normally,troubleshooting is required.Troubleshooting can be carried out from the following six aspects: 1.The power indicator is not on and the optical transceiver cannot communicate. resolvent: Verify that the power…
