摘　　要：本文介绍了一种用于激光调阻机的14路矩阵板的设计,激光调阻机采用该矩阵控制板可以同时修调多个电阻,若要增加最大可修调电阻数,只需增加矩阵控制板的数量,通过级联共同工作。该矩阵板包括了pic18f4580主控芯片,串口通信,电源模块,CPLD通道选择模块,继电器矩阵阵列。This paper introduces how to develop a kind of 14-channel matrix control panel, used in the laser resistor trimming machine. The laser resistor trimming machine can trim a number of resistors at a time with this matrix control panel. If it wants to increase the numble of resistor for once trimming, it should use more panels. The matrix control panel contains PIC 18F4580 application unit, serial communication, power unit, channel select module of CPLD, array of relay etc.
