It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an interference detection method according to an embodiment of the present invention. The technical scheme of the embodiment can be suitable for detecting the interference in the sensitivity attenuation test of the liquid crystal display module. The method may be performed by an interference detection apparatus provided in the embodiments of the present invention, and the apparatus may be implemented in software and/or hardware. The method specifically comprises the following operations:
s110, setting a preset transmission bandwidth, and calculating a transmission cycle bandwidth according to the preset transmission bandwidth.
The preset transmission bandwidth can be set in advance for a tester. Setting a preset transmission bandwidth, and calculating a transmission cycle bandwidth according to the preset transmission bandwidth, specifically comprising: setting a preset transmission bandwidth according to the specified transmission bandwidth range, and calculating the transmission cycle bandwidth according to a calculation formula and the preset transmission bandwidth, wherein the calculation formula is as follows: the transmission period bandwidth is equal to the preset transmission bandwidth/unicast byte, and the unicast byte is equal to 3 pixels × 8bits is equal to 24 bits. The tester sets the preset transmission bandwidth according to the specified transmission bandwidth range, which is 800MHz-1GHz, for example, so that the preset transmission bandwidth can be set to 960 MHz. The transmission cycle bandwidth is calculated according to a calculation formula and a preset transmission bandwidth, for example, when the preset transmission bandwidth is set to 960MHz, the transmission cycle bandwidth is 960MHz/24bits is 40MHz according to the calculation formula.
And S120, determining a frequency multiplication interference bandwidth and a risk frequency multiplication interference bandwidth.
Determining a frequency multiplication interference bandwidth and a risk frequency multiplication interference bandwidth, specifically comprising: and determining the frequency multiplication interference bandwidth and the risk frequency multiplication interference bandwidth according to the scanning off/on frequency display of a frequency spectrograph. Illustratively, a risk interference prediction line can be observed according to a waveform displayed on a frequency spectrograph, so as to obtain an intersection point of the risk interference prediction line and a transmission waveform, a frequency range corresponding to a part of the waveform between two adjacent nearest intersection points is determined as a frequency multiplication interference bandwidth, and a frequency range corresponding to the waveform between the intersection point and a zero point nearest to the intersection point is determined as a risk frequency multiplication interference bandwidth.
S130, calculating to obtain a transmission cycle bandwidth range of the clock signal to be detected, and judging whether interference exists according to the frequency of the clock signal to be detected in the transmission cycle bandwidth range and the frequency multiplication interference bandwidth.
Calculating to obtain the transmission cycle bandwidth range of the clock signal to be detected, specifically including: dividing the frequency of the clock signal to be tested by the bandwidth of the transmission period to obtain the remainder frequency; taking the remainder frequency as the clock frequency to be compared under the condition that the remainder frequency is smaller than the half transmission period bandwidth; and under the condition that the remainder frequency is greater than the half clock cycle frequency, taking the frequency obtained by subtracting the transmission cycle bandwidth from the remainder frequency as the clock frequency to be compared. Specifically, in the test process, the clock signal to be tested needs to be positioned so as to facilitate interference detection, and after the frequency of the clock signal to be tested is selected, the frequency of the clock signal to be tested is divided by the transmission cycle bandwidth to obtain a remainder frequency, so that the clock signal to be tested is located in the fifth cycle through the remainder frequency, the cycle range of the clock signal to be tested is determined, and the specific position of the clock signal to be tested in the current cycle bandwidth is determined. Comparing the remainder frequency with a half-transmission period bandwidth, wherein the half-transmission period bandwidth is half of the transmission period bandwidth, and when the remainder frequency is smaller than the half-transmission period bandwidth, taking the current period bandwidth range where the remainder frequency is located as a detection reference range and taking the remainder frequency at the moment as a clock frequency to be compared; when the remainder frequency is greater than the half transmission cycle frequency, it is indicated that the remainder frequency is closer to the range of the bandwidth of the next transmission cycle, and at this time, the remainder frequency is subtracted by the transmission cycle frequency to obtain a new frequency as the clock frequency to be compared.
And judging whether interference exists according to the clock frequency to be detected in the transmission period bandwidth range and the frequency multiplication interference bandwidth, which specifically comprises the following steps: under the condition that the clock frequency to be compared is within the frequency multiplication interference bandwidth range, judging that interference exists; and under the condition that the clock frequency to be compared is within the risk frequency multiplication interference bandwidth range, judging that the potential interference hazard exists. Specifically, comparing the clock frequency to be compared obtained by the clock frequency to be tested with the frequency multiplication interference bandwidth, and when the clock frequency to be compared is within the frequency multiplication interference bandwidth range, indicating that the clock frequency to be tested can receive the frequency multiplication interference; when the clock frequency to be compared is within the risk multiple frequency bandwidth range, the fact that the clock frequency to be compared is interfered is indicated, and then a tester judges whether the clock frequency is reserved or not according to the actual situation.
Exemplarily, the interference detection determination process is now illustrated: the preset transmission bandwidth is determined to be 960MHz, the transmission cycle bandwidth is 40MHz, and the half-transmission cycle bandwidth is 20MHz through calculation. Observing a risk interference prediction line through a frequency spectrograph display screen, obtaining intersection points of the risk interference prediction line and transmission waveforms, determining a frequency range corresponding to the waveforms between two adjacent nearest intersection points as a frequency multiplication interference bandwidth, taking the midpoint of the two adjacent nearest intersection points as a central origin point, namely the frequency multiplication interference bandwidth at the moment is-0.5 MHz-0.5MHz, and determining a frequency range corresponding to the waveforms between the two adjacent nearest intersection points and a nearest zero point of a close-distance intersection point as the risk frequency multiplication interference bandwidth, namely-0.7 MHz- (-0.5MHz) and 0.5MHz-0.7 MHz. If the selected clock frequency to be tested is 135MHz, the remainder frequency is 15MHz by dividing the transmission period bandwidth, and the 15MHz is less than the half transmission period bandwidth by 20MHz, the comparison is directly carried out, wherein the 15MHz is more than the maximum threshold value of the frequency multiplication interference bandwidth by 0.5MHz and more than the maximum threshold value of the risk frequency multiplication interference bandwidth by 0.7MHz, so that the clock frequency to be tested can be determined to have no interference; if the selected clock frequency to be tested is 155MHz, the remainder frequency obtained by dividing the transmission period bandwidth is 35MHz and is greater than the half-transmission period frequency by 20MHz, at the moment, the transmission period bandwidth is subtracted from the 35MHz to obtain-5 MHz, and then the-5 MHz is used for comparison, at the moment, the-5 MHz is smaller than the minimum threshold value of the frequency multiplication interference bandwidth, namely-0.5 MHz and smaller than the minimum threshold value of the risk frequency multiplication interference bandwidth, namely-0.7 MHz, so that the clock frequency to be tested can be determined to have no interference. And recording each parameter and the corresponding clock frequency data to be tested in a table for subsequent application.
