UR9AH身处异地的维护工程师会由于多种原因参与到远程的客户支持中。维护工程师可以接入Internet，通过巨元监控中心的安全认证，与客户现场的设备建立连接。基于东用科技《无线远程维护解决方案》，巨元可获得满足以下特征的完美系统：

　　工程现场网络无人值守，4G无线工业路由器7*24小时在线。

　　4G无线工业路由器无需另购开关电源，可通过PLC电源直接供电。

　　工程现场网络接入无需运营商布线，4G无线工业路由器通过遍布全球的4G网络快速接入Internet。

　　4G无线工业路由器集成多层次安全功能，用户无需另购其他网络安全设备。

　　提高人力资源的利用率：巨元维护人员可通过安全隧道，对现场故障工程进行分析，如可远程解决则避免维修工程师往复故障现场。如不可解决则安排配件及附近工程师排除此故障。

　　提升企业形象，创造二次价值：巨元可利用已有业务系统，实时搜集前端设备状态。如发现前端设备呈现故障特征，提早安排对此设备进行维护。这样既可大大降低设备的停机率，提升产品可靠性。又可提升企业在用户心中的形象，降低企业维修成本，为巨元在未来行业竞争中赢得高端市场提供充足的实力。PLC

　　PC/服务器：Maintenance engineers in different places will participate in remote customer support for a variety of reasons. The maintenance engineer can access the Internet and establish a connection with the customer's on-site equipment through the security certification of Juyuan Monitoring Center. Based on Dongyong Technology's Wireless Remote Maintenance Solution, Juyuan can obtain a perfect system that meets the following characteristics:



The network at the project site is unattended, and 4G wireless industrial router is online for 7 * 24 hours.



4G wireless industrial router does not need to purchase additional switching power supply, but can be directly powered by PLC power supply.



The network access of the project site does not require operator wiring. 4G wireless industrial routers can quickly access the Internet through 4G networks all over the world.



4G wireless industrial router integrates multi-level security functions, so users do not need to purchase other network security devices.



Improve the utilization rate of human resources: Juyuan maintenance personnel can analyze the on-site fault engineering through the safety tunnel, and if it can be solved remotely, the maintenance engineers can avoid reciprocating the fault site. If it cannot be solved, arrange the accessories and nearby engineers to eliminate the fault.



Improve corporate image and create secondary value: Juyuan can use existing business systems to collect front-end equipment status in real time. If the front-end equipment is found to have fault characteristics, arrange maintenance for the equipment in advance. This can greatly reduce the equipment downtime and improve the product reliability. It can also enhance the image of the enterprise in the minds of users, reduce the maintenance cost of the enterprise, and provide sufficient strength for Juyuan to win the high-end market in the future industry competition. PLC



With Ethernet interface, IP address and gateway can be configured.



orb305：



Connect the 4G/5G network and establish a VPN connection with the central access router, so that the central end can communicate with the lower PLC, and monitor and program it.



UIM/SIM card:



It is used for 4G/5G router (ORB305) to dial to the operator's network.



(2) Monitoring center side: VPN router:



It is used for the central monitoring room to access the network, establish VPN connection with the lower ORB305 wireless router, manage the lower 4G/5G router, and provide office Internet access.



Enterprise broadband access:



Use enterprise broadband provided by China Telecom and China Unicom, or commercial ADSL (including public IP address).



PC/Server:
