Internet of Things weighing system (10-200T)

The first wave of industry represented by computers, the second wave of industries represented by the Internet and mobile communication networks have passed, and the third wave of industries is now facing the Internet of Things. Various intelligent equipment applications, character sensing, have gradually spread to all aspects of society. The Internet of Things is about to replace the Internet, and the Internet is about to disappear. It is not a trend, but a reality.

Weighing equipment is intelligent and connected to the cloud service platform to achieve remote monitoring, management, and service of the weighing equipment, providing real-time status inquiry and post-closing expert services to scale users. In this way, the customer can log in to check the working status of all weighing instruments at any time with the mobile phone. If a fault alarm is found, the customer and the weighing instrument manufacturer can be notified immediately. Weighing instrument manufacturers can also pre-judge possible problems on the spot through the failure information sent back by the instrument, and bring the parts that need to be replaced directly to the scene and remedy the disease. The efficiency will far exceed the traditional service model.

Once the Internet of Things is used on the scale, the advantages of the network can be fully utilized. When the customer has a fault request, he can directly query the nearest service outlet to arrange personnel on-site service. What's more, the Internet of Things not only brings convenience, but also prevents customers from cheating and information statistics.

● Equipment area management, authority management, verification reminder;

● Operation log record, failure statistics report;

● Weighing record report management.



How much benefit does using the Internet of Things main business bring?
