使用状态机或事件结构来管理不同串口设备的通信,避免串口操作互相阻塞。 使用并行循环(parallel loops)处理多个串口设备的数据读取和处理任务。 通过测量和记录程序中各个部分的执行时间,找出瓶颈所在并优化代码。 6. 串口缓冲区管理 检查和管理串口缓冲区: 确认串口缓冲区大小设置合适,避免缓冲区溢出或过小导致频繁读写...
使用并行循环:利用多核处理器,使用并行循环(Parallel For Loops)提高处理速度。 避免轮询:使用事件驱动架构,避免在循环中频繁检查状态(轮询)。 5. 内存管理 优化数据类型:选择合适的数据类型,避免使用过大的数据类型,减少内存使用。 使用按需加载:对于大型数据集,使用按需加载技术,只在需要时加载数据,减少内存占用。
LabVIEW中的体现: 使用并行循环(Parallel Loops)或实时系统(Real-Time System)实现多任务调度。 数据通信模块(如共享变量或队列)协调子系统间的交互。 案例: 智能制造生产线:多个机器人协同作业完成装配任务。 实验控制平台:同时控制加热、搅拌和数据采集设备。 总结 使用LabVIEW开发的控制系统,如果具备自动化执行、闭环...
I have multiple parallel while loops in LabVIEW and I want to use one stop button to stop all of them. How can I do this and also have the stop button return to its initial state?
Usea functional global variable (FGV) to communicate between two parallel processloops contained within different VIs under the same target, and use a FGV tostop parallel loops with one "stop" button. The"functional" nature of the FGV means that you can create additionalfunctionality beyond that ...

Use single-process variables to transfer data between two different locations on the same VI that cannot be connected by wires, such as parallel loops on the same VI, or two different VIs within the same application instance. The underlying implementation of the single-process shared variable is...

Another decomposition implements the parallel For Loop as several sequential For Loops with some additional logic to split inputs into parallelizable pieces for the sequential loops and join the pieces back together afterward.A new feature in LabVIEW 2010, subVI inlining, is also implemented as a ...
1. LabVIEW NXG brings a new look-and-feel to the LabVIEW IDE. The new version adds a channel wire to the IDE. It is designed to simplify programming data transfer between parallel loops. Channel-wire support for FPGAs provides an asynchronous communication support for user-defined malleable vi...
