Describe the workflow of wireless digital kernel phase system of the present utility model below in detail.
When T type detector, TR type detector respectively when cable A, the B, detector sends the sound and light signal prompting and powers on, and enters test mode.
At first, T type detector and TR type detector all begin to detect the electric signal of the 50Hz of cable separately.When T type detector detected the last saltus step of signal in the A cable, entering immediately with 20ms was the duty that loop cycle sends coded signal, breaks away from cable until T type detector.The preceding 10ms of the coded signal in each cycle is 0,1 level alternating signals, and back 10ms is the zero level signal.Coded signal outputs to wireless transmitter module through the single-chip microcomputer pin, and is modulated on the frequency of 315MHz and sends.
TR type detector is also carrying out similarly work simultaneously, and only the wireless signal of TR type detector transmission is modulated on the 433MHz.In addition, TR type detector is also detecting the coded signal that T type detector sends by wireless receiving module always.As shown in Figure 5, TR type detector is a benchmark with the 50Hz electric signal of this locality, detect received T type detector signal and the time difference Δ t between the local reference signal, afterwards Δ t and the threshold T g that prior software sets are compared, if Δ t＜Tg, then provide sound and light signal prompting two paths of signals homophase, otherwise will not point out.Because time difference and phase difference value are equivalent, we have just realized the observational measurement to phase differential like this.
In the measurement operation of reality, because voltage instability, the detector cell voltage is on the low side and the manual operation erroneous judgement that causes easily test result such as improper, and because observational measurement is to send the prompting of sound and light signal homophase as whether, to seem not accurate enough, concrete.For this reason system design carry out the digital hand-held set of HD type of quantitative measurment.The digital hand-held set of HD type itself has the LCD display of one 128 * 64 dot matrix, can each state of instant playback test macro present located and test result.
In T type detector, the work of TR type detector detector, open the digital hand-held set of HD type, just can accurately measure phase difference value.The digital hand-held set of HD type detects and receives the 315MHz signal of T type detector and the 433MHz signal of TR type detector simultaneously.As shown in Figure 5, when two paths of signals is detected, we with the T type detector signal that receives as the judgement benchmark, the TR type detector signal that measurement receives and its mistiming Δ t, by self-defined algorithm time difference is scaled phase difference value then, again the phase place thresholding of phase difference value and system is compared, make the whether judgement of homophase.At last the result of test is presented on the liquid crystal display, has just realized the quantitative measurment of phase difference value.
System testing result's displaying contents comprises: differ phase place number of degrees value, leading still lag behind, whether homophase and the prompting of phase place coordinate etc.In the expression that differs the number of degrees, we adopt from 0 to 359 method for expressing to represent the phase difference value of two paths of signals, at time difference in the transfer algorithm of phase difference value, we are being 180 degree as the time T among Fig. 5=10ms equivalence, and as quantization scale the Δ t that measures are carried out transformation with this.
