Description

one

This invention relates to automation.

Devices are known for converting signals from nuclear magnetic spectrometry and electronic paramagnetic resonanceB containing a clock generator, a filling pulse generator, a series-connected accumulating counter, polling circuits and a recording unit, switches and a trigger counter, the outputs of which are connected to a code-H1 converter.

However, the known devices are complex.

The aim of the invention is to simplify the device.

To do this, a trigger divider is inserted into the device, a potential-pulse valve is a voltage converter in a time interval, two inputs of which are connected respectively to the input of the device and to the output of the clock generator, and the output is connected to the potential input of a potential-impulse valve connected by a pulse input to the output of the generator " the filling pulses, the outputs of the potential-pulse valve and the clock generator are connected via switches, respectively, to the counting inputs on aplivayuschego counter and trigger divider whose output is connected with the control inputs pakaplivayuschego counter interrogation circuit and the recording unit through the switch - to the counting input of the trigger counter.

The drawing shows a block diagram of the device.

Olo contains a generator / clock pulses connected to the voltage converter 2 in the time interval, an potential-pulse filling valve 3, to the potential input of which the converter 2 is connected, and to the pulse input - the generator 4 filling pulses and accumulating counter 5.

The device also contains a polling circuit 6, a registration unit 7, a trigger divider 8, a trigger counter 9, a code-voltage converter 10, a double switch // and a switch 12.

Before starting, the setting of the Smoothing degree and the discreteness of the sweep range are made using three switches // and 12 that switch the input circuits of the accumulating counter 5, the trigger divider 8 and the counter 9. This will change the conversion factor of the counter 5, the division ratio of the divider 8, and the inputs the triggers of the lower bits of counter 9 are switched. Thereafter, the supply of a pulse to the input is started. The installation of counters 5, 9 and divider 8 into the initial state and start of the generator / clock pulses, which controls the further operation of the entire device, is made. The resonance absorption signal is fed to the input of the analog-to-5 converter in converter 2 at a time interval. The output signal of the converter opens the potential-impulse valve 3 and, at the input of the accumulating counter 5, the generator 11 receives pulses from the generator 4 pulses of filling. Their number is proportional to the magnitude of the time interval, which, in turn, is proportional to the input signal. After several conversion cycles, the counter 5 will contain the sum of the codes formed 15 at each conversion. To ensure that the value of the exit code corresponds to the average value of the accumulated amount, the interrogation circuit 6 is connected only with the trigger bits of the counter 5. Through the given ne-20 switch / / number of conversion cycles, depending on the selected degree of averaging, the output impulse divider 8 interrogates circuit 6 polling, will start the registration block 7, which records the average value of the conversion results 25, and will set the accumulation counter 5 to the initial state, preparing it for the next measurement cycle. Further, the same impulse will go to counter 9, added one to the “one ode” in it, thereby setting 30, thereby the next value of the voltage of the sweep floor. In the future, the device will work similarly until such time as the scan field reaches its maximum value, after which the overflow signal of counter 9 will turn off the generator / clock pulses. The process of extracting the resonant absorption signal is over, rm.
