The purpose of the present invention is to increase the speed of the device. The goal is achieved by the fact that an encoder and memory elements are entered in the setting unit, and transfer pulse storage units are entered in the preliminary counting unit, the input of the generator of pulse packets is connected to the first inputs of the memory element, the setting unit and the device, the second input of which connected to the second input of the setting block and the first input of the switch, the second input of which is connected to the output of the encoder, the input of the encoder is connected to the first output of the generator of packets of pulses, the second output of which connects The second input of the element is us, the switch outputs are connected to the corresponding output unit and the inputs of the preliminary counting unit and the inputs of the corresponding decades of the preliminary counting unit, the outputs of which are connected to the first inputs of the corresponding transfer pulse storage nodes, the second inputs of which are connected to the corresponding the inputs of the preliminary counting unit, the output of the setting unit of the settings and the output of the memory element, and the outputs with the counting inputs of the next decades, the output of the last node While the transfer pulse is connected to the output of the preliminary counting unit, the input of the first decade is connected to the input of the preliminary counting unit and to the third input of the device. FIG. 1 is a block diagram of the device; in fig. 2 shows an example of a specific embodiment of a pulse packet generator and an encoder; in fig. 3 is an example of a specific implementation of the transfer pulse storage unit. The device contains a block for setting settings 1, a block for preliminary counting 2 and a counter 3. A block for setting settings consists of memory element 4, a generator of pulse packets 5, an encoder 6 and a switch 7. Pre-counting block 2 contains decades 8, 9, 10, cells " OR 11, 12, 13, 14, the memorization nodes of the reversal imiuls 15, 16, 17 (in principle, the number of bits in the preliminary counting unit is unlimited). Pulse generator 5 (see Fig. 2) is a valve with one input and ten outputs, but not built on delay cells 18. Its input is connected to the first input of the device, the first nine outputs are connected to the inputs of the encoder, and dec with a reset input of memory cell 4. Encryptor 6 (in this example) contains nine transistor amplifiers 19, the collectors of which are interconnected by diodes 20. The inputs of the amplifiers are the inputs of the encoder, the outputs of which are connected to the collectors of the corresponding order amplifiers 19. The node for recording transfer pulses 15, 16, 17 contains (FPG. 3) cell "P1LR1 21 and cell" AND 22. The first (pulse) input of the cell "OR is associated with the input of the node, the second input with the inverting output of the cell" And and the inverting output of the OR cell is connected to the input input of the AND cell, the second input of which is connected to the second input of the node. The output of the node is the output of the OR cell. Plot a illustrates operation of the node in the absence of a signal from the memory element at the second input (zero potential). Plot b corresponds to the case when the second input of the node contains a signal from memory element 4 (negative potential). Switch 7 (FIG. 1) may consist of decadic switches or may be controlled by an external device via a second input of the device. In the initial, inoperative state, the element (cell) of type 4 is in the dead state, the generator of pulse packets 5 is in a state of rest, the transistors of the amplifiers 19 are locked and there is a negative potential at all outputs of the flatbed 6. At the output of the switch 7 signals are missing. And the second inputs of nodes 15, 16, 17 receive zero signal levels from memory location 4 (“And 22 cannot work”). The device works as follows. When a pulse arrives at the first input of the device, a generator of pulse packets 5 is triggered and phase-shifted impulses are generated at its outputs. These pulses are fed to the inputs of the amplifiers of the encoder 6, causing them to alternate operation, and due to the diode connection between the collectors, when the first amplifier triggers on all the collectors, a positive impulse is observed. When the second amplifier triggers, the impulses are in TC on the collectors of the second and subsequent amplifiers, etc. The response of all cells of the distributor on the collector of the last amplifier amplifies the ninth pulse, at the eighth and accordingly 7th, 6th, 5th, 4th , 2 and 1 pulses on the corresponding order of the outputs of the encoder 6. Thus, one operation of the generator of a packet of pulses 5 causes the appearance of nine pulses of pulses, with the number of pulses from one to nine, on nine outputs of the encoder 6. These nakat through comment torus 7 and through the corresponding cells "OR 11-14" arrive at the counting inputs of decades 8, 9, 10 and at the input of block 2. If, for example, you want to write a value of 3.509, then using switch 7, the input of decade 8 (the youngest bit) will be connected to the ninth output of the tweeter 6, the input of decade 9 will not be connected to any of the outputs of the encoder, the input of the decade 10 will be connected to the fifth output of the tweeter, and the output of unit 2 through the cell "OR 14 will be connected with the third output of the encoder. Then, each time the generator of a packet of pulses 5 is started, 9 pulses are sent to the input of decade 8, O and 5 nmpuls at the inputs of decades 9 and 10, and 3 pulses at the output of block 2, and the recording is performed simultaneously for all decades.

The memory cell 4 is transferred to the state of "1 pulse at the first input of the device and is reset to ZERO by the tenth pulse of the pulse generator of the pulses 5. Thus, for the duration of the pulse generator of the pulses 5, the memory 4 is in the state of" 1 and the second the inputs of the nodes 15, 16, 17 are given a signal "1 allowing the operation of the cells" AND these nodes.

The transfer pulse storage unit (15, 16, 17) operates in the trigger mode with separate inputs in the presence of a "1" signal at the second input and in the amplifier mode at a zero signal at the second input. The falling edge of the pulse removed from the output of the node in question is the operating one, i.e. the decade following the NODE counts the PULSE at the moment when the pulse at the output of the transfer memory unit disappears. If a transfer pulse appears during the operation of the generator of pulse packets 5 at the output of the corresponding node for storing the pulse PULSE, the signal is transmitted (the trapsistor of the cell 21 is forbidden). This state will be preserved until the end of operation of the generator of the pulses 5 pulses, and the transfer pulse will be transmitted the next decade after the end of the pulses arrival from the switch 7, which eliminates the failure due to the overlap of the counts and transfer pulses. Thus, the transfer signal is stored for the duration of the operation of memory cell 4 and pulse generator 5 and transmitted without delay when pulse generator 5 and memory cell 4 are in their original state.

To record a number in preliminary counting block 2, no more than 10 cycles are required, regardless of the number of bits in the preliminary counting block (the number of cycles may be less if you write the number in the ARC code, for example, in binary-decimal). Moreover, the first cycle can be combined with a pulse at the input.

When pulses arrive at the third input of the device, the memory cell 4 will be in the zero state and the transfer pulses will be passed by the nodes 15, 16. 17 almost without delay.

The specified device can operate in the footage counting mode or in the theoretical weight determination mode without alterations and readjustments. In the first case, the recording signal of the base length is fed to the first input of the device, and the information on the length of the remainder of the third input. In the second case, the length information 6 must arrive at the first input of the device.

The principle of operation of the device is not violated, if the recording of information is known in a binary-decimal or other code.

The use of the device provides for faster performance (more than 3-4 times) of the accounting systems. In addition, the execution of pulsator of the PULSES package generator, the npfratora of the transfer pulse memory cells makes it possible to simplify the quality of the device as a whole, which in turn will expand its area of application and allow it to be used, in particular, on HIGH-SPEED rolling mills. The device can also be used in various automation systems as a scaling device, in particular, for measuring length, overflow, and stretching.
