Description

1. The invention relates to measuring technique and can be used to measure the geometrical dimensions of moving objects, for example, on automatic lines for processing fish. A device for measuring the geometrical dimensions of moving objects is known, containing a block of photoelements, a processing unit. The signal meter and the CO recorder. A disadvantage of the known devices is the low accuracy of measuring the coordinates of objects of complex shapes. The closest to the invention is the device l measuring geometric dimensions of moving objects containing a line of photodetectors, a block of keys whose inputs are connected to the outputs of photodetectors, a block of conjunctors, the first input of each of which is connected to the output of the corresponding key of the key block, a disjunctor whose inputs are connected to the outputs of the block of conjunctors, and the recorder 23 devices wide functionality due to the impossibility of measuring the coordinates of points of inflection, such as the coordinates of the beginning or end of the dorsal fins in some types of fish. The purpose of the invention is the expansion of functional capabilities. The goal is achieved by the device for measuring the geometric dimensions of moving objects, containing a line of photodetectors, a block of keys, whose inputs are connected to the outputs of photodetectors, a block of conjunctors, the first input of each of which is connected to the output of the corresponding key of the key block, a disjunctor, whose inputs are connected to the outputs of the conjuncture unit, and the recorder, are equipped with a pulse generator, an additional instructor, the first input of which is connected to the generator output, the trigger output of which Connected to the second input of the additional conjunctor, a clock pulse sensor, the output of which is connected to the trigger input by a pulse counter, the input of which is connected to the output of the additional conjunctor, a decoder, the inputs of which are connected to the counter outputs. ka, .a outputs are connected to the second inputs of a block of conjunctors, an additional block of conjunctors, the first inputs of which are connected to the outputs of the decoder, and the rest to the outputs of the corresponding keys, an additional disjunction, whose inputs are connected to the outputs of an additional block of conjunctors, and the output to the trigger and counter reset inputs, and the delay element connected between the output of the first disjunctor and the recorder. The drawing shows a block diagram of a device for measuring the geometrical dimensions of moving objects. The device contains a line of 1 photodetectors, a block of 2 keys, a block of 3 conjunctors, the first inputs of which are connected to the outputs of a block of 2 keys, a disjunctor C, the inputs of which are connected to the outputs of the block 3 of conjunctors, a delay element 5, a recorder 6 connected via an element 5 to the disjunctor output 4, a pulse generator 7, an additional conjunctor 8, the first input of which is connected to the output of the generator 7, a trigger 9, a sensor 10 clock pulses connected to the input of the trigger 9, a pulse counter 11, a decoder 12 connected to the output of the counter 11, tional block 13 and additional conjunctors disjunctors and whose inputs are connected to outputs of TK unit, and an output - to the reset inputs of flip-flop 9 and the counter 11. The device operates sleduyui1im manner. . I, To clarify the principle of operation of the device, consider the case where a portion of the object to be monitored, for example, a fish fin, is in the measurement zone. Suppose that at the moment of device start-up () the top photodetector of line 1 is illuminated. The generator 7, conjunctor 8, trigger 9, sensor 10 clock pulses, counter 11, decoder 12, block 13 of conjunctors and disjunctor 14 form a distributor with a variable distribution coefficient, which can be limited only sequentially, starting with large values, by supplying single signals to conjunctors block 13. For example, when the output of block 2 keys will be zero levels (all

the photodetectors are darkened), the outputs of the conjunctors of block 13 will also have zero signals and the disjunctor will not generate a reset signal for the tri1-gera 9 and counter-11. In this case, the distribution coefficient will be maximum (equal to seven for the number of photodetectors under consideration). If, for example, the upper photodetector of line 1 (moment) is illuminated, then a single signal from the corresponding key of block 2 prepares the upper conjunctor of block 3 and the lower xy-junctor of block 13 for operation. When started from the sensor 10 of the counter 11, the outputs of the decoder 12 appear unit level at the moment of appearance at the last output of the unit, the lower conjunctor of the block 13 outputs a single impulse of short duration, which through disjunctor 1 knocks trigger 9 and counter 11 to zero.

; As a result, the distribution coefficient becomes one less as compared to the case, KOI-and all photodetectors are blacked out. The delay element 5 serves to not let the short duration pulses to the input of the recorder 6, the moments of change in the state of the two encoders 12 appearing at the output of the block. When the photodetectors of the ruler 1 are sequentially illuminated (moments t, t), the distribution coefficient decreases.

If the intermediate photodetector of ruler 1 is illuminated (for example, at the moment), the distribution coefficient does not change because the appearance of a single signal at the output of block 2 of keys corresponding to the illuminated photoreceiver does not result in the appearance of a single impulse at the output of the speakerphone 1 when same you during the decoder 12 will be one. As a result, a single signal from this output of the decoder 12 passes through the corresponding conjunctor of the block 3 to the output of the disjunctor k and through the delay element 5 on the recorder input 6, which records the signal and informs about the change of the required coordinate.

The invention makes it possible to extend the functionality of a device for measuring the geometrical dimensions of moving objects.
