Digital device for measuring single and multiple impact impulses

A digital device for measuring single and multiple impact impulses comprising:

• a converter for converting impact impulses into electrical signals;
• an amplifier of electrical signals, the input of which is connected to an output of said converter;
• an electrical signal filter, the input of which is connected to an output of said amplifier;
• a measuring unit, for measuring the peak value of impact pulses and having inputs and outputs, a first input of which is connected to an output of said filter;
• a tens comparator of said measuring unit having inputs;
• a units comparator of said measuring unit having inputs, a first input of said units comparator being connected to a first input of said tens comparator and together serve as said first input of said measuring unit;
• a successive separation unit, for successive separation of impact pulse time intervals and pauses therebetween, and having an input connected to said first input of said measuring unit and outputs;
• a base frequency generator of said measuring unit having an output;
• a separation unit, for separation of a first transcription pulse and a group of further reset pulses from a train of high-frequency pulses within a given interval between two successive impact pulses having inputs and outputs, a first input and a second input of which are connected to a first output and a second output of said successive separation unit and a third input of which is connected to a first output of said base frequency generator, which serves as a first output of said measuring unit;
• a tens register of said measuring unit having inputs and outputs;
• a units register of said measuring unit having inputs and outputs;
• gate means of said measuring unit providing electrical connection of the output of said tens comparator, the output of said units comparator and said outputs of said base frequency generator with said inputs of said tens and units registers;
• a reset line of said tens and units registers;
• a digital-analog converter of said measuring unit having a group of inputs connected to a group of outputs of said tens register and of outputs of said units register and having an output connected to a second input of a group of inputs connected to a group of said tens comparator and of said units comparator;
• a readout unit, for readout of information on single and multiple impact pulses, having inputs, a first and a second input being connected to the input of said tens register and of said units register, which serve respectively as a second and a third output of said separation unit and to said reset line which serves as a second input of said measuring unit;
• a setting unit, for setting operational modes for measuring single and multiple impact pulses, having an input connected to a second output of said separation unit, a first output connected to a fourth input of said separation unit and a second output connected to a fourth input of said readout unit, said transcription pulses being effective to transfer the measured peak value information of the inpact pulses to storage means prior to a resetting of said measuring means by said resetting pulses, and the measurement of a next succeeding impact pulse, whereby the device is reset and prepared for further measurements in the interval between pulses.
