Claims

The goal is achieved by the fact that the device containing discriminators, whose inputs are connected to the signal sensor, and the outputs are connected to the same inputs of elements AND of the first group, the other inputs are connected to the shift register, and the outputs are connected to the corresponding memory elements, and the elements And the second group, the inputs of which are connected to the outputs of the corresponding elements of And the first group, and the outputs are the output of the device, is entered a trigger, the inputs of which are connected to the sensor of signals and to the register shifted and formed atel pulses connected to the output of the flip-flop and to the input of the shift register. 39 The drawing shows the block diagram of the device. The device includes a signal sensor 1, discriminators 2, elements AND 3 of the first group, a trigger, a pulse shaper 5, for example, a clock generator, a shift register 6, memory elements 7, and elements 8 of the second group. Wu: Trsystvo works as follows. In the initial state, the signals at the output of sensor 1 are absent, the elements of the 7 memory are reset, and the signals at the outputs of all elements And are zero. The circular shift register 6 is in such a state that it is. work begins with the first exit. With the passage of the information carrier in the zone of the sensor 1, the pulse signals are generated at the output of the latter, the polarity, level and mutual temporary position of which determine the transmitted information. The discriminators 2 determine the level and polarity of the signals. The outputs of the discriminator are connected to the first inputs of the elements AND 3 The first impulse from the output of sensor 1 overturns the trigger and starts the clock generator 5, which controls the operation of register 6. Signals from the outputs of register 6 and the corresponding discriminator turn on a certain element FROM and then memory element 7 These parameters are determined by the output signal of register 6 and discriminator 2. The outputs of memory elements 7 in certain combinations are connected to I8 elements. The output element is IV. 4 is based on a certain combination of input signals. When a signal appears at the last output of shift register 6, trigger + returns to the initial state and disrupts the operation of the clock generator 5. Introducing the trigger and pulse generator can significantly increase the reliability of the device. DETAILED DESCRIPTION OF THE INVENTION An image recognition apparatus comprising discriminators, the inputs of which are connected to a signal sensor, and the outputs are connected to one input of elements AND of the first group, the other inputs of which are connected to a shift register, and the outputs are connected to the corresponding memory elements, and elements of the second group The inputs of which are connected to the outputs of the corresponding elements AND of the first group, and the outputs are the output of the device, characterized in that, in order to increase the reliability of recognition, it contains a trigger, the inputs which is connected to the signal sensor and the shift register, and a pulse shaper connected to the trigger output and to the input of the shift register.
