Claims

ts Delivered by one, it is achieved that in the digital integrator, containing the roar, the pSer counter and the OR element, the inverter and the EXCLUSIVE OR element, the n -1 inputs of which are connected to the reversible counter, nth input - from the senior input reversing counter, and outputs. are the output timed output counter, the output of the inverter is connected to all information inputs of the reversing counter, except the low-end input, which is connected to the input of the inverter, to the output LOAN of the reversing counter, and to the first input of the OR element, the second input of which is connected to the output PORENOS counter, and the output and the setup input of the RECORDING RECORD counter input is the first input of the integrator, the INPUT input is the input of the integrator, and the high-order output of the counter is with the output of the integrator's sign. The drawing shows a block diagram of an integrator. The integrator contains reversible 1, element 2 EXCLUSIVE OR, element OR 3, inverter 4, input 5 frequency setpoint signals, input 6 frequency feedback loops, information output 7 of the integrator, output 8 digits. The integrator works as follows. After switching on, the counter 1 is cleared. In the absence of setpoint signals and feedback, the counter code is 1 NO, the outputs of element 2 are all zeros. Let, for example, the input of the COMPOSITION of the counter 1 be five input pulses of frequency f,. Counter 1 will sum up this task, the code Nj 5 will be set at its output. Now let us input to the Subtraction of counter 1, for example, 10 pulses with frequency foc. After the first five pulses at the counter outputs, the code is set equal to O after the pulse of that pulse arrives at The output of the LOAN of counter 1 in terms of Wits is a zero-level pulse, which is fed to the first information input of the counter (its low-order bit) through inverter 4 to its other information inputs and through the element OR 3 to the installation input RECORD of counter 1. The code in the counter is written N -1, at the output member 2 through Vits code is equal to one, the output on landmark 8 Vits l (significant bit of counter 1). After the arrival of the next 4 pulses Q, the code N -5 will be set at the output of the counter, at the output of element 2 - the code Now we give the input to the COMPLEX of counter 1, for example, 1O pulses with frequency f-x. After the arrival of the first pn pulses at the exhaust of the counter J, the service sets a code equal to its maximum capacity N. At the output of the escort code 2, the code will be equal to O. After the sixth pulse arrives at the output of the TRANSFER of the counter 1, the output level is zero at the output of this time is |, and the output of the inverter 4 is O), which through the circuit OR 3 passes to the installation input RECORDER 1. The output of the counter is set to 1. The same code appears on the output of element 2, the sign changes to the opposite . The subsequent pulse sequences of the sequence f will increase, respectively, the codes at the outputs of counter 1, the output 7 of element 2 will set the code corresponding to the number 5, In the 1-th 4th information control systems about the difference of numeric sequences tf j {i} T QQ (-t) taking into account the sign from the outputs of counter 1, with one sign corresponding to the direct code, and the other sign - inverse. The effect of the introduction of such electric drives in the national economy will be from 890 to 2300 rubles. per unit of product, depending on the performance of the drive. Claimant Inventory integrator containing a reversible counter and an OR element, characterized in that, in order to increase accuracy and reduce hardware costs, it contains an inverter and an EXCLUSIVE OR element, the ti -1 inputs of which are connected to the n -1 outputs of the reversible counter, n - The th input is with the high output of the reversing counter, and the outputs are the acformed outputs of the integrable A, the output of the inverter is connected to all the information inputs of the reversing counter, except for the lower-order input, which is connected to the input of the invert ora, with a LOAN output of a reversible counter and with the first input of the element OR, the second input of which is connected to the output TRANSFER of the counter, and the output to the direct input of the RECORD of the counter, the input of the COMPONENT of the counter is the digital input of the integrator and the high-order output of the counter is the output of the sign of the integrator. .
