Be used for control change device 5 and read the pulsation receiver algorithm program coding of input signal sampling based on the algorithm that utilizes discrete Fourier transform in the definite time.This conversion realizes having the band pass filter that sin (x)/x responds under the fixed frequency.This frequency depends on the sampling rate of converter 5.This algorithm uses two accumulators (real number with imaginary number).
Real accumulator is the sinusoidal sum of products in each sampling and sampling frequency angle.Imaginary accumulation is each sampling and the sampling frequency phase cosine sum of products.If use 4 times of sampling frequencies, then should locate to take a sample at 0 °, 90 °, 180 ° and 270 ° to required frequency (4dft).The sine of these angles and cosine are 1,0 or-1.Therefore, this algorithm is reduced to following rule:
To 0 ° of sampling, the value of reading transformation into itself's device 5 is added real accumulator;
To 90 ° of samplings, the value of reading transformation into itself's device 5 is added imaginary accumulation;
To 180 ° of samplings, the value of reading transformation into itself's device 5 is deducted from real accumulator; And
To 270 ° of samplings, the value of reading transformation into itself's device 5 is deducted from imaginary accumulation.
If sampling rate is 8 times of required frequencies (8dft), then should in real number and imaginary accumulation, add or deduct additional sampling 0.707.8dft sampling has response preferably for occurring in obscuring of 50Hz main signal for the frequency, but it has other defective.
Taking a sample, filter bandwidht is narrow more more at most for bandwidth one sampling point that has determined filter total time.Have been found that in the practice that best filtering sampling rate is that 500Hz is above and uses 4dft, and use 8dft below the 500Hz.This make obscure problem reduce the most remarkable.
Owing to must measure signal power, so sampled data is stored in (not drawing among the figure) among the formation of " first in first out " accumulator with the frequency that is higher than every 500msec.Like this, can by to accumulator formation sue for peace and routinely sum of squares of treatment obtain tolerance to desired signal power.
In order from fluctuating signal, to remove main line frequency component and harmonic wave thereof, have been found that in the practice that must make total sample time is the multiple of main line frequency inverse.Therefore, if the main line frequency is 50Hz, then be necessary for the multiple of 20msec sample time.
Can will depend on the ability of timer in the microcontroller 8 to the number of times that signal is taken a sample.Have been found that in the practice that the timer with 2 μ sec increment work is fit to.
For reducing the step amplitude between the adjacent required frequency, time between the sampling is per 4 or 8 take a sample t and t+2 μ sec with regular as far as possible model selection, or actually per 48 then to depend on what programmed be 4 or 8 dft, like this, can select the frequency of 2 μ sec increments to microcontroller (working) with 2 μ sec increments.
Above-mentioned these variablees in the algorithm can be all enroll among 8 microcontrollers 8 with program.Equally, if necessary, all variablees all can carry out reprogramming.Therefore, in case install after 2 mounting characteristics determines or install, all variablees just can have been determined.If necessary, can use 16 microcontrollers.
The explanation of said apparatus 2 is with reference to being undertaken by the operation of input start pulse signal in the fluctuating signal.This trigger impulse can be got the form of pulse telegram.The information that is contained in this telegram can be any form, can insert the information in this telegram.For example, this information can be the electrically charge rate.This trigger impulse can be programmed, so that have only the device 2 that just butts up against when this rate of charge is brought down below certain predetermined value on the relevant output port 9 to operate.Information in this telegram can be the time of comparing with the scheduled time of remaining.This information can be the price of other commodity (as combustion gas), operates with 2 pairs of miscellaneous equipments of trigger equipment or system (as with system or equipment of gas driven etc.).This trigger impulse also can comprise the optional factor, so that can be optionally certain type equipment be turned on and off.
Therefore, will be appreciated that device 2 or one group of device 2 can be used for the indirect load control of arbitrary dimension energy network.Although carry out with reference to 50Hz feeder cable system, will be appreciated that the system that can be used for having other frequency through suitable this device 2 of improvement to installing 2 explanations of carrying out.
