一种用于闸位计的SENT接口设计

A SENT Interface Design for Sluice Meter

设计了一种用于闸位计的单边沿半字节传输(SENT)接口,该接口一方面可以减少闸位计的布线,另一方面减少采集器IO口的占用数量。接口采用低功耗可编程逻辑器件CPLD实现。经过逻辑仿真,实际测试该接口设计正确。

A single edge nibble transmission wiring of the sluice meter on the one hand,and duce.A low-power complex programmable logic conducted on computer in this paper.Test result （SENT） interface for the sluice meter is designed,which can reduce the on the other hand,the number of IO ports required for the controller is re- device （CPLD） is used for implement for the interface.Logical simulation is for the interface is correct.
