I-YIHTONG, etholakala e-Henan, e-China, yenze umtshina wokuchichima womgqomo kadoti ohlakaniphile, ohambisana nenzwa ye-A13 yenkampani yethu yohlelo lokusebenza olukude lwe-ultrasonic.
I-YIHTONG isebenzisa ubuchwepheshe benzwa ye-ultrasonic njengendlela yokuthola, idlulisa ulwazi lwesikhathi sangempela kanye nedatha ngemojula yokuxhumana ye-NB-IoT, futhi iqaphe isimo esichichimayo semigqomo kadoti esabalaliswe endaweni yokusebenza ngokuhlanganisa neplatifomu yokuqapha ifu ye-GIS.
