⏹ 系统需求系统由测试台和测试柜两部分组成。

测试柜：主要由电路控制箱盒工控机构成。

工控机包含PCI-1710HG ，PCI-1760，PCL-839等三块卡。

PCI-1760为8路继电器输出卡，用来控制测试电路的档位切换，电源的切换，以及步进电机驱动器的启动。

PCI-1710HG 为高增益AD 采集卡用来采集控制回路的反馈电压，获取力矩器在不同角度下的力矩。

PCL-839用来控制步进电机驱动器，使力矩器力矩器定子转动到合适的角度。

测试台包括以静压空气轴承为支撑的测试主轴和梁体组件（6）组成活动部分：以角位移传感器（3），音圈力矩器（4），电子转换放大器组成的力矩反馈电气部分；由带动被测电机定子座（7）旋转、定位用的步进电机与涡轮蜗杆和步进电机等组成的传动机构部分⏹ 系统描述力矩测试原理当梁体组件受到被测电机的转矩Ma 作用时，它立刻偏离原来平衡位置。

其偏移角α的讯号经位移传感器、电子放大器、在音圈力矩器回路中产生一个反馈电流If ，并且产生一个反馈转矩Mf ，此转矩与被测电机转矩Ma 相比较，实现模拟量加矩再平衡。

通过PCI-1710GH 取出与反馈电流If成正比的采样标准电阻端电压Ur ，就是与被测电机转矩成正比的数值。

案例名称：基于研华ATE 设备的高精度力矩测试仪系统行业分类：ATE （工厂自动化）地点：软件实施软件部分使用DELPHI6.0开发应用程序。

整个软件包括数据采集、数据动态显示、步进电机驱动、数据后期分析处理，数据库操作、测试报表输出等几部分。

1、测试流程控制模块。

主要通过操作PCI-1760，PCL-839来完成。

根据测试大纲的步骤依次操作继电器的切换。

A good signal connection can avoid unnecessary and costly dam-age to your PC and other hardware devices. This chapter provides useful information about how to connect input and output signals to the PCI-1761 via the I/O connector.3.2 Isolated Digital Input ConnectionsThe PCI-1761 has 8 isolated digital input channels designatedIDI0~IDI7.Each of isolated digital input channel accepts 10~50 V DC voltageinputs, and accept bi-directional input. It means that you can apply positive or negative voltage to an isolated input pin (Vin ). The figure below shows how to connect an external input source to one of the card's isolated input channelsFigure 3-1: Isolated digital input connectionsChapter 3 Signal Connections3.3 Relay connectionsAfter power on, the initial relay output status of PCI-1761 is shown asbelow:Figure 3-2: Relay output connectionA write operation to I/O address, BASE +0, will change the outputstatus of each relay. For example, if Bit 0 of BASE +0 is set "1" (logic high), relay 0, K0, will switch from position "NORMALLY CLOSED", R0_NC, to position "NORMALLY OPEN", R0_NO. This means thatLOAD2 will be de-energized, while LOAD1 is energized.To summarize, the "COMMON" line connect to the "NORMALLYCLOSED" line, if the corresponding bit is set as 0 (power-on initialstatus). Otherwise, if the corresponding bit is set as 1, then the"COMMON" line will connect to the "NORMALLY OPEN" line..PCI-1761 User’s Manual22Advantech Co., Ltd.Advantech Co., Ltd.23PCI-1761 User’s Manual Appendix AAppendix A SpecificationsTable A-1: Isolated Digital InputTable A-2: Relay Output Number of Input Channel8Optical Isolation3750 V DC Opto-isolator response time25µs Over-voltage Protect70 V DC Input Voltage VIH (max.)50 V DC VIH (min.)10 V DC VIL (max.)3 V DC Input Current 10 V DC1.6 mA (typical)12 V DC1.9 mA (typical)24 V DC4.1 mA (typical)48 V DC8.5 mA (typical)50 V DC 8.9 mA (typical)Number of Output Channel8Relay TypeSPDT (4 Form C and 4 Form A)Rating (resistive)3 A* 250 V AC or 3 A* 24 V DC Max.
