| Abstract: | Aimming at procedures for the electrical load system while multi-task executes at one time,the CPU has low utilization and may block other tasks,the LabWindows/CVI multi-threading technology is used to build two independent thread pool threads used for data acquisition and data processing.The multi-thread technology solves the program task blockage.CPU utilization and system reliability and stability are increased.Using the TSQ thread-safe queue to pass data between threads can solve the problem of data synchronization.Experiments show that the multi threading can advance deadly accuracy of the system performance,and improve real-time and reliability in data acquisition. |
