Renesas Electronics will implement a demonstration related to the next-generation communication standard "Ethernet TSN (TIme-SensiTIve Networking)". TSN-related demonstrations were implemented at the "SPS IPC Drives 2016" exhibition in Nuremberg, Germany.
TSN is currently being targeted by the IEEE802.1 TSN Task Force for automotive and industrial network promotion standardization, consisting of multiple standard (function) groups. Renesas will give a demonstration of the four major categories of functions. The first is "transmission control of time-controlled streaming media data", the standard is "IEEE 802.1Qav", which preferentially transmits data of high priority by pre-reserving the transmission bandwidth required for each transmission level. The second is "an extension of the planned transmission process", the standard is "IEEE 802.1Qbv", and data transmitted using the standard is assigned to one of eight levels. Each level of data communicates at a cycle specified by each level.
The third is the time step, the corresponding standards are "IEEE 1588v2" and "IEEE 802.1AS". Master-slave control that synchronizes time with each network node is specified.
The fourth is "frame insertion/super priority transmission", and the corresponding standards are "IEEE 802.1Qbu/" and "IEEE802.3br". This technique inserts time-limited frames into the transmission of other frames, thereby minimizing delays. Renesas participated in the "AVnu Alliance" centralized testing activity held in August 2016, confirming the consistency and interconnectivity of the standards related to frame insertion.
Custom Piezoelectric Components
The piezoelectric ceramic sound-generating element, especially a lead-free piezoelectric ceramic sound-generating element, is mainly composed of metal flakes and piezoelectric ceramic flakes. The sound pressure generated by this new structure piezoelectric sounder is proportional to the number of piezoelectric ceramic sheets. By increasing the number of piezoelectric ceramic sheets, the required large sound pressure is easily achieved.
