摘　　要：现有的数字传感器至少由2根数据线和2根电源线共4根线组成,每根线均有明确的分工和极性,不能接错和短路,否则易损坏设备,需专业人员才能安装和维护;数据传输加密方式有限,易破解。利用本公司研发的"智能终端整机供电用二线制数据/电源共线传输装置及方法",将数字传感器的连线减至2根,且无极性、可短路,简化了系统的连接,提高系统的可靠性,使安装和维护变得极为简便。数据传输采用特殊的加密方式,极难破解。The present digital load cell is composed of 4 lines at least, which has 2 data lines and 2 power lines. The strict specialization and polarity make a wrong connection or a short circuit very dangerous. Once it happens the equipment is prone to be damaged, and the installation and maintenance will become difficult for you; the data transmission encryption methods are not only limited, but also easy to be cracked. Our company＇s inventive patent ＂the two-wire data/power collinear transmission device and technique with intelligent terminals and for complete machine power supply＂ （Patent No. 201510078098.7） can decrease the wires of digital loadcells to two Non-polarized wires. If a short circuit happens, it will not damage the equipment. Our patent product simplifies the system connection and improves the system reliability, thus making the instailation and maintenance very simple. The special encryption method adopted by the data transmission is very hard to be cracked.
