[0017] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments. figure 1 It is the synchronization control flowchart of the 4-thread data acquisition system of the present invention:
[0018] The computer CPU used in this example is a 4-core I7 processor, and the data sampling device is an Acqiris U1065A digitizer, and its real-time sampling rate can reach 8GSamples / s. Head file data sampling equipment includes measuring wheel encoder and QSB-M acquisition equipment. The multi-threaded data acquisition system is divided into 4 threads. The synchronization control flow chart of the multi-threaded data acquisition system is as follows figure 1 As shown, the 4 threads work independently of each other in a loop form during data acquisition and writing. Among them, the radar data acquisition task is completed by thread 1 and thread 2, the header file data acquisition task is completed by thread 3, and the data writing...
