| Zusammenfassung | The paper describes a system developed for the data acquisition and multiprocess control of mechanical quantities rapidly varying with time. Data acquisition and the suppression of disturbances by control take place synchronously while electric input signals are continually generated for electromechanical exciters of rotation quantities. The data acquisition and multichannel control system (DAMCS) is based on a VAX computer-aided and VAX real-time software-aided VXI system. With the DAMCS , a data acquisition rate of more than 300 000 words/second in normal operation, and of approx. 1,2 million words/second in FIFO-DMA operation has been achieved. The network system has direct access to a 40 Mbyte memory and to a 4 Gbyte hard disk. The cycle time achieved for the control unit is 30 μs. at the PTB, the DAMCS is used for the calibration of angular acceleration transducers. It will be extended and further developed, the aim being the full exploitation of its capabilities for the realization on highly precise dynamic measurement of mechanical quantities varying with time (both angular and translational accelerations, forces and torques). |
