摘　　要：针对传统的信号源只能产生单一的信号、不可调等缺点,及本次某型遥测装置的测试需求,提出了一种基于上位机控制输出并且可以手动调节的检测工作台设计方案。本文对检测工作台结构、工作原理进行了详细的设计和分析,以及上位机的简单介绍,该检测工作台以FPGA、数字量板、继电器为核心,具有集成度高、多路复用、结构简单、操作便捷等特点。检测工作台包含2路数字量、13路可调的模拟信号和1路-230~0 V模拟电压,13路模拟信号通过上位机实现0~30 V模拟电压调节,1路-230~0 V模拟电压由220 V逆变器得到。试验表明该检测工作台的数字量输出完全正确,模拟量的输出误差小于1%,完全满足此次测试的要求,并且抗干扰能力强,具有很好的复用性和实用价值。To address the shortcomings of traditional signal source that can only produce single signal and can not be adjusted,and to meet the testing requirements of a certain type of telemetry device,a design scheme of detection table based on the output controlled by upper computer and adjusted by hand is proposed.This paper discusses the detailed analysis and design of the structure and working pri-nciple of the detection table,as well as a brief introduction of the upper computer.The detection table is centred on FPGA,digital mea-suring board and electric relay with the characteristics of high integration,multiplexing,simple structure and convenient operation.The 13 channels of analog signals are adjusted by the upper computer to achieve 0~30 V analog voltage.The 1 channel of-230~0 V analog voltage is obtained by the 220 V inverter.The test results show that the digital output of the test table is completely correct,and the out-put error of the analog output is less than 1%,which fully meets the requirements of the test,and has strong anti-interference ability,good reuse and practical value.
