资料介绍

为减少太阳能热水器中主控制器与线控器之间的布线成本,采用与非门芯片74HC00设计了一种一线通信接口转换电路。利用Multisim虚拟仿真软件测试了在通信线长度为50m,分布电容为2nF的条件下,通信速率可达57600b/s。应用结果表明:该电路具有通信速率高、节省布线成本、工作稳定可靠的优点。

NAND gate Chip 74HC00 was adopted to design a single-wire communication interface conversion circuit for re- ducing the cost of wiring between the main controller and wired remote control in solar water heaters. The communication line length of 50 m was tested with Multisim virtual simulation software under the condition of the distributed capacitance of 2 nF, and the communication rate can reach 57 600 bit per second. The application results show that the circuit has the advantages of high communication rate, can save wiring cost, and is stable and reliable.
