MES wireless communication networking technology based on 433MHZ

To trace and track enterprise assets (man, machine, materials and orders), record and carry real-time, accurate, complete and consistent shop-floor data, an effective wireless network communication method based on 433 MHz is proposed in this paper. The needed network equipments, network architecture and some examples are also introduced. Application results show that it is a very effective method to reduce/eliminate error-prone and tedious manual data processing activities and discover bottleneck, diagnose process errors, adjust schedules for unexpected disturbances by 433 MHz wireless network technology in the situation of MES application.
