Description

The invention relates to a measurement technique and is intended for rapid analysis and registration of the processes occurring in the assemblies and assemblies of mobile machines during their field or stand tests. The aim of the invention is to improve the accuracy and reliability of the data recorded in the device.

The drawing shows a block diagram of a measuring-recording complex for the study of the operation of mobile machines.

The complex contains sensors I, amplifiers 2, first controlled switch 3, storage 4, second controlled switch 5, driver 6 signals, device inputs 7-10, output 11. Sensors 1 are connected through amplifiers 2 to the first 3 and second 5 managed switch. The outputs of the first controlled switch 3 are fed to the drive 4, the outputs of which are connected to the other inputs of the second switch 5. The output of the latter is connected to the first input of the signal conditioner 6 signals, to the output of which is the output of the device, a display unit (not shown ). The first, second, third, and quarter inputs of the device are connected to the control inputs of the first 3 and second 5 switches, the drive mode selection input, and the setup input of the specified signal conditioning transducer, respectively.

The signal shaper 6 is designed to quickly determine during the experiment the characteristics of the studied processes of the dynamics of the mobile machine in order to select the most informative signals, which need to be recorded first, as well as to perform, if necessary, the processing recorded on the magnetic data storage device an experiment. As such devices, one of the microcomputer models can be used with an appropriate set of peripheral tools (for example, Electronics-NC series, Electronics-C5 series) or specialized express analyzers functioning according to a hard algorithm or programmed by the user.

The device works as follows.

In the test mode, the mobile machine signals from the outputs of the sensors 1, installed in various of it. nodes arrive at the inputs of the amplifiers 2. The latter produce amplification and normalization of the signal, driving it to the required level. From the output of the amplifiers 2, the signals arrive at the inputs of the first switch 3 and the first inputs of the second switch 5; The ring switch 5, according to the commands at input 8, produces a serial connection of the outputs of the amplifiers 2 to the input of the driver 6 signals. In the latter, in accordance with the command programmed in it by the command, from turn 10, the evaluation of the characteristics of the processes under study (for example, variance, standard deviation, etc.) is performed. The resulting signals are fed to output 11. In accordance with them, the operator sets at input 7 the addresses of those m channels, the information on which is of the greatest interest for the study. In this case, the drive 4 under the 0 control commands at the input 9 register-. rips data

In the express-processing mode, signals from the outputs of sensors 1 are not received, the drive 4, using command 9, switches on the reproduction of information and the data from its outputs are transmitted to the inputs of the second switch 5. The latter, by signals received at its control input, produces connecting the researcher of the drive output channel of interest to a signal shaper 6, which performs data processing. The resulting signals are fed to output 11, to which an indicating unit (not shown) can be connected, and displayed on it. At the same time, since time is not a determining factor in this mode, processing can be performed using more complex algorithms that require increased computational costs, but allow one to obtain estimates of finer signal characteristics (for example, spectral and correlation functions).
