When equipment competition shifts from a single function to delivery, service, and full life-cycle experience, manufacturers find a practical problem: the equipment has been sold, but service still stays at phone calls, WeChat groups, and on-site troubleshooting. Tongwei Smart treats remote after-sales as an ongoing service capability that equipment manufacturers can productize. What the customer needs is a faster response. What the manufacturer needs is lower after-sales cost and a more stable repeat-purchase relationship. The point where the two meet is remote operations.
Equipment servitization does not mean adding a screen to the product, or developing a separate app for each customer. It needs a complete service chain: the equipment can connect to the network, key status and fault codes can be reported, exceptions can be notified by rules, after-sales staff can view the information remotely and handle it together, dispatch to the site through a work order when necessary, and finally form equipment and service records that can be queried.
The value of doing this is that the manufacturer no longer has to wait passively for a repair request. For a clear exception, information can be obtained in advance. For a problem that needs on-site handling, the engineer can set out with the data. For a fault that occurs repeatedly, it can push improvement of the product and the installation process in return. Service gradually changes from a "cost center" into an entry point for customer relationships, product iteration, and value-added business.
Tongwei Smart provides a remote after-sales product package for equipment manufacturers, based on SG/BEC industrial gateways, SDS/IOC acquisition and control modules, and the AIoT operations platform. It supports multi-protocol access, alarms, remote diagnosis, ledgers, work orders, inspections, reports, and API/OEM support. Tongwei Smart does not replace the customer's core controller. The specific protocols, remote-control permissions, branded pages, and interface scope are confirmed per project.
One workable path is this: first verify one equipment model with a paid sample unit or a small-scope PoC, then retain the protocol templates, alarm rules, page configuration, and delivery checklist, and finally move into small-batch replication. Making service capability into a product does not rely on a one-time large investment. It relies on each delivery being more standard than the last one.
