The switch 16 is designed to organize the output of information from the counter

13-15 on the bus for indication and registration, and can be filled out of group prohibition elements on each counter, the outputs of which are alternate with other counters are combined and are the information output channel of the switch. The output of the information of each parameter to the channel is provided by alternately connecting the enabling signals to the bar elements of the prohibition of the corresponding parameter.

The display unit 17 is designed to display digital information generated by the device on the remote display, on the display of the collective use of technological personnel.

The shaper 18 is designed to generate, over each input signal, distributed in time code bursts of pulses 1-2-4-8 from the fourth to the seventh outputs to record the value of the registers 19.1-19.3 to the counters 22.1-22.3 and the control signals on the outputs first to third to form the output signal from each counter 22.1-22.3 when they overflow, to set the elements 23.1-23.3 of the memory in the zero (initial) state, to block the recording of information in the registers 19.1-19.3 for a time forming code pulse bursts.

In the illustrated embodiment (Fig. 3), the driver 18 contains a trigger 25, the output connected to the installation input is the zero state of the binary 4-bit counter 26, the counting input of which is connected to the clock input of the driver 18 and connected via an inverter 27 to the decoder gating input 28, the information inputs of which are connected to the discharge outputs of the counter 26. The outputs of the decoder 28 are connected to the inputs of the inverters 29 and 30. The RS flip-flop 31, the inverter 32 and the elements 1PI 33-35 whose inputs are input to the outputs of the former 18 .

The multiplier 8 (9-12) frequency works as follows.

S-input shaper 18 pulse code packets; in FIG. 3, the S-input of the trigger 25 does not receive pulses) the counters 22.1-22.30 and the triggers 23.1-23.3, 25.31 are in the initial zero state (the reset bus in Figures 2 and 3 is not shown). Registers 19.1–19.3 of memory by signal Record from output 3 of generator 18 fixes the current values of the corresponding parameter. The trigger 25 (FIG. 3) maintains the counter 26 also in the zero state. The clock pulses from the generator 1, arriving at the counting input of the counter 26, do not change its state, but the passage through the inverter 27 to the gate C input of the decoder 28 ensures that the zero state of the counter 26 is outputted by the second output of the driver 18.

When a pulse arrives at the signal input S of the imager 18 of bursts of pulses, the trigger 25 (Fig. 3) is set to one and thereby enables the counter 26. The counter 26 changes its state for each clock pulse from the generator 1 (FIG. 1). at the outputs of the decoder 28, time-separated pulses are formed, corresponding to each state of the counter 26.

In this example, for each cycle of operation of Form 11 18, when a single pulse arrives at its signal input, 12 clock pulses of the generator 1 are required (see the time diagrams in Figure 4). During the cycle of operation at the outputs from the first to the third multiplier, the corresponding signals Transfer, Reset, Record Lock are formed, and at the outputs from the fourth to the seventh, code packets of pulses 1-2-4-8, respectively.

At the beginning of the next cycle of processing the signal Record from output 3 of generator 18 in registers 19.1- 19.3 memory is fixed and the current values of parameters H, RO P; p F coming from block 2 and sensors 5 and 6 are stored and stored. 4-8 from the code outputs from the fourth to the seventh generator 18 arrive at the second inputs of the switchboard RSLR 20.1-20.3, on the first inputs of which there is a code of the value of the corresponding parameter (Nd, B5, p,

Vd, H), recorded in reg for sources 19.1-19.3, and as the code packs of the former 18 are formed at the outputs of the switches 20.1-20.3, they are formed and recorded into counters 22.1-22.3 of each of these values. If there is an overflow of counters 22.1-22.3 during the cycle, the signal from the Q of the control first output of the imaging unit 18 (corresponding to the 11th cycle) passes to the outputs of the I 24.1-2АЗ elements and, accordingly, through the elements OR 21.1,21.2 to the counters 22.2,22.3 , 5 following bits or the multiplier output (in case of overflow of the counter 22.3).

On the same eleventh clock of generator 1, the control third output of driver 18 receives a signal to unlock the write to memory registers 19.1-19.3, and after the twelfth clock of generator 1, driver 18 is reset to the initial 25 state (trigger 25 at input R is set to O). Subsequent pulses of the generator 1, having passed to the control output 2 of the driver 18, set the elements 23.1-23.3 of the memory to the initial zero state. Thus, when any multiplier arrives at the third input (the signal input of the generator of 18 code packets of pulses), a sequence of pulses n at its output forms a sequence of pulses N in accordance with the expression

The absolute maximum error of calculating each multiplier 8 (9-12) frequency does not exceed one pulse of the output sequence for any values of the number a.

The clock frequency F from generator 1 is selected based on the maximum frequency F of the following pulses in accordance with the expression F 12 F, since the summation cycle in each multiplier is performed in 12 cycles.

The device for program account of the products works as follows.

In the initial state, the multipliers are 8-12 frequencies, the counters 13-15 are in the initial zero state. The generator 1 generates time-separated read and write information pulses, as well as clock pulses with a frequency FO.

In block 2 of information input, the required values of rolled parameters are set: the strip thickness is nominal (H), the strip width is nominal (V), the density (p) of the metal, the value codes of which are fed to the second inputs of the corresponding frequency multipliers 11.9.8.

In the absence of rolled signal from the sensor 3 the presence of the product prohibits the passage of pulses from the sensor And the length through the element 7 to the third input of the frequency multiplier 8.

During the strip rolling process, the sensors 5 and 6 continuously determine, respectively, the actual value of the width W and the thickness H of the rolled strip, the value codes of which are fed to the second inputs of the corresponding frequency multipliers 10 and 12.

When the rental occurs in the zone of sensors 3.5 and 6, the signal from the output of the product 3 sensor permits the pulsing of length pulses from sensor 4 and element 7 to the third input of multiplier 8, and which multiplies the sequence of pulses of length I coming from sensor 4. the value of the density code p of the metal coming from block 2. The number-pulse code L p from the output of multiplier 8 by multipliers 9 and 11 is multiplied by

From the output of multiplier 11, the number-pulse code of the theoretical mass of metal M is fed to the counting input of counter 13 and to the first input of the reversible counter 16. The number is the pulse code of the actual mass of metal MD, LpB H from the output of multiplier 12 to the counting input of counter 14 ( accounting for the actual output of rolled products in accordance with the average values of the actual width and thickness at the current time) and to the second input of the reversible counter 15.

In the process of operation, in the reversible counter 15, a qualitative (advance or lag) and a quantitative comparison of the actually produced rolled stock with the theoretical one is made. The rental information from the outputs of the reversible counter 15 through the switch 16 comes to be displayed in block 17. When the scoreboard ratio is, the minus sign (advance) is displayed, and when the ratio M ™, the plus sign (lag) is displayed. Based on the indications of block 17, the process personnel decide how to carry out the rolling process.
