Description

 1A62208

The invention relates to measurable. As a result, a comparator 8 is present at the inputs at the same time as information - O. and, where Q. is the number of pulses counted in the last period of the reference frequency, Q, is the number of pulses counted in the previous period.

With Q; . The unit i- appears at the second output of the comparator 8, which results in the Acceleration signal on the pointer 9. At Q. 0 ;, the unit appears at the third output of the comparator 8, which leads to the flying technique, as well as to automatic control of the speed of moving objects and program control of technological processes.

The aim of the invention is to simplify the device and increase its information by measuring the current. standby display speeds. | "

The drawing shows the block diagram of the device.

Pulse displacement sensor 1 is associated with a 2-pulse counter. Last through block 3 of the operative yy ma-i-

7, the digital comparator 8, two outputs: connected to the indicator 9. The third output of the comparator 8 is connected to the information input of the demultiplexer lOj whose outputs are connected to the indicator 9. The address input - the multiplexer is connected to the output of the comparator 11, one input of which is connected to the code setpoint 12 of zero speed, and the second input is connected to the output of the RAM block 3 and to the input of the digital indicator 13 of the current Speed,

The device operates as follows:

When an object passes fixed sections of the path. Sensor 1 generates short pulses. Counter 2 counts - Precision setting device 7 forms

temporarily information fixed

Demultiplexer input 10.

Depending on the signal at its address input, associated with the output of the second comparator 11, there appears a unit at the first or second output of the Demultiplexer 10. If at the address 1 second

Qi, Qo and unit appears at the first output, which is connected to the input of the mode indicator 9, which highlights the steady-state speed signal on the indicator. When Q,. “Q, there is one at the address input of the Demultiplexer 10 (output of the second comparator). This results in the appearance of a unit at the second output of the Demultiplexer and the display of the mode of the Stoke signal on the indicator 9,

The signal to the input of the second comparator comes from the code unit 12 of zero speed. It characterizes the setting to the minimum speed, below which the object is considered to be stopped.

the counter before dropping to zero is transmitted to the RAM block 3. Here the information is stored in simultaneously transmitted to the block 4 of the time delay and through the controlled key 6 to the input of the comparator 8
