The lever attached to the rack mounted on a support, allows to increase the pressure acting on film.
iV12i-1where V1the voltage of the first section. This allows you to have on output terminals of the power plant any required voltage and to ensure its stability depending on the load station and force of the waves by varying the amount included in the sections.Shunt and sectional electronic keys managed by the second reversible counter, provide the switching sections in the voltage regulation. The voltage divider and an analog-to-digital Converter are measuring body diagram of voltage regulation. The first numeric comparator, a counter, a second logical element And the generator stable pulses and the first differentiator provide code generation voltage amplitude which is stored in the memory register. The second numeric comparator, the first reversible counter, a second differentiator and the first logical element And serve to return the circuit to its original state for formation of the next code amplitude. The third numeric comparator, a memory register that specifies the register, the third and fourth logic elements And form a regulating effect on the second reversible counter for increasing or decreasing the voltage p is a device and the control circuit piezoresistors; in Fig. 4 is a block diagram of a system for automatic regulation of the voltage of Fig. 5 is a plot of the signals at the outputs of the main elements of the regulation.Wave power plant comprises a support 1, piezoresistor 2, the rack 3, the hinge 4, the lever 5, the float 6, clamping the shield 7, shunt electronic keys 8 1, 8 N sectional electronic keys 9 1, 9 N, the voltage divider 10, analog-to-digital Converter 11, the pulse counter 12, the first 13 and second 14 reversible counters, the first 15, second 16 and third 17 numeric Comparators, the memory register 18, the first 19 and second 20 differentiator specifying register 21, the first 22 and second 23, the third 24 and fourth 25 logical elements And the trigger 26, the generator stable pulse 27, the logical elements NOT 28 1, 28 N. Piezoresistor 2 consists of N sections, each of which contains the top 30 N and the lower 32 N substrate with electrodes, peopleco 31 N and the dielectric spacer 33 nThe power plant operates as follows. With the approach of the wave float 6 rises and larger lever arm 5 impact force. The lever rotates on the axis 4 and the presser shield 7 affects piezoresistor 2, on output terminals which receive the electromotive force. After passing voltara 2. When you approach the next wave cycle repeats.The voltage divider 10 is connected to bus piezoresistors 2. Output AC voltage is input to analog-to-digital Converter 11. Code of the instantaneous voltage supplied to the second input of the numeric comparator 15. On its first input connected to the output of the pulse counter 12, which will be formed code voltage amplitude. Until the code is instantaneous values of the voltage more code at the output of the pulse counter 12, the signal is present at the output is LESS than the numeric comparator 15, which prepares the logical element And 23 to the second input. From pulse generator 27 via the first input of logic element And 23 receives the pulses to the counting input of the pulse counter 12. Code at its output increases and in case of equality codes at the inputs of the comparator 15 logical element And 23 is locked, the pulse counter 12 does not arrive until the moment when the code at the output of analog-to-digital Converter 11 increases. This process continues until it reaches the amplitude value of the instantaneous voltage. After instantaneous value of the voltage becomes less than the amplitude, the code at the output of the counter 12 becomes more code at the output of the Ala differentiator 19 generates a pulse to the input of the write memory register 18, where code is logged in the amplitude of the voltage output of the pulse counter 12. Simultaneously, the pulses from the differentiator 19 trigger 26 is reset to zero state and the logical element And 23 is closed by the third input. The same signal in the reversible counter 13 is filled in with code voltage amplitude from the output of the memory register 18. This code is supplied to the first input of the comparator 16, and at its second input receives the code of the instantaneous voltage that is smaller at this time, the amplitude value of the voltage, so the output is MORE of comparator 16. This signal is a logical element And 22 prepared by a third input signal from the inverted output of the trigger 26 is prepared on the second input and the generator 27 is starting to get a pulse on the subtractive input of the reversible counter 13. Code at its output decreases. This process continues until the instantaneous value of the voltage reaches a minimum, then the code on the second input of the comparator 16 becomes greater than the first input and a signal output is LESS than the comparator 16. This signal is differentiated by the differentiator 20 and fed to a single output of the trigger 26, which changes its state and prepares for the third vevee state. The code on the first input of the comparator 15 becomes less code instantaneous voltage and begins the process of measuring the amplitude of the next wave voltage whose code is written in the memory register 18. This code is supplied to the second input of the comparator 17, to the first input of which the output setting register 21 filed code of the given voltage amplitude.If the current amplitude of the output voltage is less than specified, you receive the output signal MORE of the comparator 17, this signal prepares the first input of the logical element And 25 after the code is generated, the amplitude of the voltage from the differentiator 19 passes the pulse to a summing input of reversible counter 14. A signal at the output of the first discharge. When this control signal to the sectional electronic key 9 1 the first section of piezoresistor. Simultaneously supplied through the logic element is NOT 23 1 low shunt on the electronic key, 8 1, which is closed. When this output terminals connects the first section of piezoresistor 2.According to the results of the second cycle of measuring the amplitude of the voltage will be introduced in the second section of piezoresistor 2 with one degree higher voltage is the voltage amplitude in the work will be introduced additionally, the first section of piezoresistor 2. In this section keys 9 1, 9 2 will be included, and shunt 8 1, 8 2 will be turned off.As a result, the voltage each time increases by one step. This process will continue until such time as the voltage amplitude reaches specified, then the logical element And 25 is closed by the first input.If the amplitude of the voltage to increase and become more defined, then to receive the output signal is LESS than the comparator 17 preparing for the first input element And 24. After the formation of the next code in the amplitude of the voltage from the differentiator 19 through the logical element And a 24 receives a pulse to the subtractive input of the reversible counter 14 and the partition switching the voltage at the terminals of piezoresistor 2 is reduced by one step.Changing the settings, wave or load on the terminals of piezoresistor will be supported by a specified voltage through the respective switching sections piezoresistor.Due to the expansion of the range of changes in the pressure acting on piezoresistor, the invention allows to increase its efficiency in the 2 to 5 times. The proposed wave power plant allows to produce any given napryazhennostyakh allows you to ensure that the control deviation is not more than 0.004 percent. Performance is determined by the frequency generator. When the frequency of the pulse generator 18 20 kHz and the eight elements of the circuit setting the output voltage from zero to rated can be carried out by 1.25 x 10-3C. When increasing the number of digits and the speed of the generator accuracy can be increased. To enhance the power station and the stability of the generated voltage wave section can contain multiple units installed side by side and working on a common load. 1.
