Now, the leading domestic manufacturers follow the manual assembly mode introduced in the early technology, although some enterprises have only customized assembly tightening systems. There is a growing demand for comprehensive assembly system that can collect multi-type data. We present new type comprehensive assembly system, a system for enabling workers to collect multi-type data by combine multiple devices, including control station, tool cart, PDA, tightening equipment, measuring equipment, confirmation equipment. The system introduces a new solution that leverages common assembly systems and other type hardware to efficiently collect multi-type data, not only tightening data. For the convenience of the workers’ operations, this system has two types of clients, running on the Android system and the Windows system respectively. One, running on the Windows system, install in control station to finish works nearby. Another one, running on the Android system, can work with a tool cart that carry different types of devices and can be moved easily to any places with workers. To support electric devices connection, the tool cart equips with a wireless router, connecting the electric devices in the cart. We have implemented the system and show that it (1) operates multiple type of process, tightening, measuring, photoing and verifying, (2) running on two kinds of operating system, Android system and Windows system, (3) can prevent equipments in the tool cart from disconnecting from server, and (4) Can handle any sudden and unexpected incidents that occur during the operation process.


Railway Industry, comprehensive assembly system, tool cart, multiple types of data fusion, coexistence of multiple operating systems
