What is Dai-Nichi Electronics' "Train Radio System"?
The train radio system is used for communication of information related to train operations between train crews and the operation control center, contributing to the safe operation of trains. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ Our train radio system is broadly categorized into three types, allowing us to build a system tailored to our customers' needs. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ● Type A / Full Duplex Communication can occur in both directions between the control center and the vehicle, similar to a telephone call. By synchronizing the audio phase of each base station to the fastest base station, we minimize degradation of call quality. ● Type B / Half Duplex The control center uses full duplex, while the vehicle side uses a simplex radio. The control side can communicate in both directions, but the vehicle side cannot receive while transmitting. ● Type C / Simplex Neither the control center nor the vehicle side can receive while transmitting. The devices used and the system diagrams are clearly explained in color in the catalog. ↓↓↓ Please take a look at the catalog download ↓↓↓

Company information
Since our founding in 1981, we have continued to challenge new technologies. "What kind of communication fits our customers better?" By listening to each individual case, we have created numerous products, including remote control devices, analog radio devices, dam telemetry systems, and home security systems. As we consistently provide services from planning and development to maintenance, we have received the evaluation that "even though the company is small, the products are top-notch." From circuit boards to systems, we provide solutions that can only be offered by Dainichi Electronics, even for just one device.
