好越达打菲软件说明书
软件说明书一、打菲软件工厂生产流程图解。
二、软件总体操作流程新增款号---新增定单-----新增裁单-----打菲、打印裁床单、打印车间收发日报表----入菲-----工介录入----工价执行------件工日报表。
-----月报表处理------查看月报表方面的报表。
三、新增款号第一步输入款号名（款号名由：数字，汉字，字母，下划线组成，最长不能超过20个字母，款号不能重复），第二步输入工序（工序的意思是做这个款的衣服的工序是什么）点插入就行了每点插入一次工序栏就多一道工序，一般的要比这个款的工序多留几个，比如说某个款衣服工序有十二道，那插入工序的时候可以插到十六道多留几个以便心以后要加工序，插入工序后点‘默认工序’默认工序的意思是按上到下从1依次排列下来。
如果不按这个顺序可以手工输入。
第三步输入工序名，工序名的意思是工序的名称，比如说梭边，车裤脚等。
第四步保存注释：‘从…复制’的意思是如果有旧款工序和要新建的款的工序是一样的就选择旧款进行复制，这样就节省了输入工序和工序名的时间。
四、新增定单这个介面是新增定单介面，第一步输入定单号（定单号的意思是下单的单号然后要选择款号，表示这个单订的是这个款）其实只要输入定单号和款号就可以保存了，其他的都可以不要输入，这个要按工厂的实际情况而定，如果需要输入的就选择性的输入。
定单明细是可以选择要不要输入的（定单明细的意思是：客户订单明细表）。
点系统管理里面的设置就会出现上面这个介面，这里不打勾新增定单就不会出现定单明细。
五、新增裁单点存盘打印后出现：点是：点否：汇总表就出现在下一页。
存盘不打印是保存退出的意思。
存盘打印，是保存然后打印出来。
裁单是裁床要裁衣服的明细表。
六、印菲点打印后，电脑桌面下的任务栏会出现印菲有两种方式，方式是打印某扎。
这种方式就是只打印某一床的指定扎号，比如说打印机在打印整床的时候碰到停电的情况，那么就没有必要已经打印的重打，只要把后面没有打印的打完就行了。

The slope is 0.5A/us. The frequency is 100Hz. Output overshoot is lower than ±5%.Protection requirementShort circuit protection: when outputting short circuit, the input power will lower and will not have any affect. After ending the short circuit, the system will recover automatically.Overcurrent protectionOCSET: within 110%-180% of maximum load (with rated voltage), when outputting overcurrent, the output will go to hiccup mode. After ending the overcurrent, the system will recover automatically.Configure RPLIDAR A3 Scan FrequencyThe motor speed control signal MOTOCTL can be configured directly via the USB adapter of RPLIDAR A3. Therefore, the RPLIDAR A3’s scan frequency can be modified by invoking the related functions in the SDK to configure the motor speed.Without the USB adapter, users can also control the speed by setting the PWM duty cycle of MOTOCTL. Please note that the PWM frequency is 20kHz. For more detailed parameter and index, please refer to the datasheet.Please refer to the RPLIDAR protocol and application note for more information and the SDK for the sample code on RPLIDAR scan frequency.SDK UsageSLAMTEC provides RPLIDAR SDK support on both Windows and Linux platform. And users can embed the SDK source code to other operational system or embedded system quickly. Please refer to the SDK document for more information.Pre-Heating for Best PerformanceThe scan core will be heating when start working. We recommend pre-heating RPLIDAR (Start the scan mode and the scan motor is rotating) for more than 2 minutes to get the best measurement accuracy.Ambient TemperatureRPLIDAR’s measurement resolution is sensitive to the ambient temperature. Improper use may even damage the sensor. Please avoid using RPLIDAR in extreme high temperature (>40 degree) and too low temperature (<-10 degree).Ambient LightCompared with RPLIDAR A2 series, RPLIDAR A3 performs better to resist ambient light interference, which supports it to work properly in outdoor environment.RPLIDAR A3 can work in two modes: enhanced mode and outdoor mode.Enhanced mode is designed for indoor environment. Typical indoor light (including situations without light) will not affect the performance of RPLIDAR. Strong light (such as high power laser) will harm the optical system of LIDAR, which should be avoided.During outdoor mode, RPLIDAR A3 can work normally to detect objects under direct ambient light. However, the ranging distance might be shorter under strong direct sunlight and it is still necessary to protect the optical system from direct sunlight.Image and Table IndexF IGURE 1-1I TEMS IN THE RPLIDAR D EVELOPMENT K IT (3)F IGURE 1-2T HE RPLIDAR (4)F IGURE 1-3RPLIDAR A DAPTER (4)F IGURE 2-1C ONNECT RPLIDAR A3 AND USB A DAPTER (5)F IGURE 2-2C ONNECT THE USB A DAPTER TO PC VIA M ICRO-USB C ABLE (5)F IGURE 2-3C HOOSE USB A DAPTER D RIVER FOR I NSTALLATION (6)F IGURE 2-4S TART P AGE OF USB A DAPTER D RIVER I NSTALLATION (6)F IGURE 2-5R ECOGNIZED S ERIAL P ORT N AME M ATCHED WITH THE USB A DAPTER (6)F IGURE 2-6R OBO S TUDIO L OGIN P AGE (7)F IGURE 2-7T HE L IDAR P LUGIN IN R OBO S TUDIO (8)F IGURE 2-8T HE S UPPORTED C OMMANDS OF RPLIDAR IN R OBO S TUDIO (8)F IGURE 2-9T HE S CAN O UTLINE BY RPLIDAR IN R OBO S TUDIO (9)F IGURE 2-10T HE M OTOR S PEED A DJUSTMENT D IALOGUE OF RPLIDAR IN R OBO S TUDIO (10)F IGURE 3-1RPLIDAR A3P INS (11)F IGURE 3-2RPLIDAR P IN D EFINITION AND S PECIFICATION (11)F IGURE 3-3RPLIDAR A3P INS R EFERENCE D ESIGN (12)F IGURE 3-4RPLIDAR P OWER A DAPTER I NPUT S PECIFICATION (12)F IGURE 3-5RPLIDAR P OWER A DAPTER O UTPUT S PECIFICATION (13)F IGURE 3-6RPLIDAR P OWER A DAPTER L INE/L OAD R EGULATION (13)。

同时，模组内集成了可以使用逻辑电平驱动的电机控制器。
开发者可以使用该电机驱动器使用PWM信号对电机转速进行控制，而从控制RPLIDAR扫描的频率或者在必要时刻关闭电机节能。
关于模组的使用、接口信号定义等请参考后续介绍。
USB转接器USB转接器自带拨码开关，使用该开关可实现波特率115200和 256000两者间的切换，方便连接RPLIDAR A3和之前的型号。
注意与RPLIDAR A3一起工作时，请将该USB转接器切换至256000波特率。
图表 1-3 RPLIDAR A3 USB 转接器实物图模组连接与使用介绍设备连接1)将开发套装中提供的RPLIDAR A3模组的连接线与USB适配器进行连接。
图表 2-1 连接RPLIDAR A3与USB转接器图2)将USB转接器通过Micro-USB线缆与PC连接，并将电源适配器一端连接至电源，另一端连接至USB转接器。
如果PC已经启动，在USB线缆连接后，可以观测到USB转接器指示灯点亮，此时RPLIDAR A3模块并未转动。
图表 2-2 连接USB转接器与Micro-USB实物图USB适配器驱动程序安装USB适配器采用CP2102芯片实现串口(UART)至USB信号的转换。
因此需要在PC系统中安装对应的驱动程序。
其驱动程序可以在配套的SDK包中找到，或者从Silicon Labs的官方网站中下载：/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx这里以Windows系统下为例，演示安装过程。
通过前几步操作将USB适配器与PC相连后，执行CP2102的Windows驱动程序安装文件(CP210x VCP Windows)。
请按照操作系统的版本选择执行32位版本(x86)或者64位版本(x64)的安装程序。
图表2-3 选择USB转接器驱动程序进行安装图表2-4 USB转接器驱动程序开始安装界面按照系统提示完成安装过程后，可以在[控制面板]->[设备和打印机]窗口中看到识别到的USB适配器所对应的串口名。
（下图为COM65）图表2-5 识别到的USB转接器所对应的串口名使用评估软件SLAMTEC在机器人管理与开发软件RoboStudio中提供了可视化插件Lidars用于评估和调试。
通过该插件，用户可以直观地观测到RPLIDAR实时的测距扫描结果，并且可以保存测距结果至外部文件供进一步分析。
目前该软件需要运行在Windows平台下，对于Linux和MacOS用户，可以使用SDK中提供的其他示例程序。
请确保RPLIDAR A3模组已经通过USB转接器连接至PC，且已经安装了前文所述的驱动程序。
运行RoboStudio，注册账号并登陆。
图表2-6 RoboStudio登录界面如果连接正常，则将看到如下界面，点击文件->雷达选项，左侧弹出雷达浮动窗口，然后展开串口，连接至PC的雷达将出现在列表中，点击该雷达图标即可在雷达下方展开工具图标列表，左侧为调速按钮（雷达转动方可启用），右侧为工具栏按钮，点击工具栏按钮可在主工作界面上打开工具栏选项，如下图所示：图表2-7 RoboStudio的Lidars插件工作界面其中串口下列出的雷达显示了当前连接雷达的序列号、版本及型号信息。
所有对RPLIDAR可进行的操作均已在工具栏列出：按钮图表2-8 Lidars插件操作按钮说明点击扫描采集按钮，则可以在主工作区中看到当前的扫描图，默认电机旋转参数设定在10hz左右：图表2-9 Lidars插件显示的雷达扫描的轮廓在主工作区鼠标右键菜单中可以选择不同的测距范围从而实现对扫描画面的缩放。
测距核心的扫描速度（转速）可以通过画面最后的文字读出。
故障排除在内部测距系统工作异常或激光器发射功耗异常时，测距核心将自动进入保护状态。
演示工具以及SDK接口可以获得当前测距核心的工作状态。
如果发生故障，则可发送重启命令要求测距核心重启。
电机调速在实际运行中，为了适应不同的工作环境，满足特定的工作需要，用户如果需要不同的电机旋转速度，可以通过按钮来实现。
点击此按钮后，按钮下方会弹出速度调节的对话框和仪表盘，用户可以直接填入数字来指定具体的转速，填写完成后，电机将自动按照设定的转速旋转；用户也可以直接拖动进度条至指定的转速。
主工作区左上方将显示当前的实际转速。
例如，下图主工作区右上方显示的转速为11.93Hz。

对RPLIDAR A3扫描频率进行控制使用RPLIDAR A3的USB转接器可以直接调节电机速度控制信号MOTOCTL，用户可以直接调用SDK中相关函数进行调节电机转速，从而修改雷达扫描频率。
如果不使用USB转接器，用户需要自行设定MOTOCTL的PWM占空比来进行调速。
请注意PWM的频率为20kHz，更详细的参数指标请参考Datasheet文档。
请参考RPLIDAR协议规范与应用文档了解详情，或者参考SDK中关于获取RPLIDAR扫描频率的代码。
使用SDK进行开发SLAMTEC提供了对RPLIDAR进行开发的配套SDK。
该SDK支持Windows、Linux操作系统，且用户也可以通过SLAMTEC提供的SDK源代码快速将SDK移植到其他的操作系统或嵌入式系统当中。
请参考SDK文档了解详情。
预热与最佳工作时间由于测距核心在工作中将产生热量，建议在RPLIDAR工作（开启扫描模式、扫描电机开始运转）2分钟后使用。
此时测距精度将达到最佳水平。
环境温度当环境温度与常温差距过大将影响测距系统的精度，并可能对扫描系统的结构产生损害。
请避免在高温（>40摄氏度）以及低温（<-10摄氏度）的条件中使用。
环境光照相较于RPLIDAR A2系列雷达，RPLIDAR A3具备更强的抗环境光干扰能力，支持在室外环境下正常工作。
