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.
