Detailed Description
The conception and technical effects of the present invention will be clearly and completely described in conjunction with the following examples to fully understand the objects, features and effects of the present invention. It is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and that other embodiments obtained by those skilled in the art without inventive effort are within the scope of the present invention based on the embodiments of the present invention.
In the description of the embodiments of the present invention, if "several" is referred to, it means more than one, if "multiple" is referred to, it is understood that the number is not included if "greater than", "less than", "exceeding", and it is understood that the number is included if "above", "below", "within" is referred to. If reference is made to "first", "second" it is to be understood as being used for distinguishing technical features and not as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
Referring to fig. 1, an FA connector polarity test method according to an embodiment of the present invention includes the following steps:
s100, controlling a light source device to send optical signals to all input end channels of the FA connector according to a preset sequence;
in this step, optical signals are sent to the input channels of the FA connector according to a preset sequence, so as to perform polarity test after all the input channels in the FA connector are subjected to light passing one by one. In general, in an optical fiber transmission system with a large data transmission capacity, an FA connector used in the optical fiber transmission system generally includes a plurality of input channels, so as to prevent one or more input channels from being missed for polarity test when the polarity test is performed on the FA connector, or to prevent the same input channel from being tested multiple times when the polarity test is performed on the FA connector, and thus, after the light is transmitted to each input channel in the FA connector through the light source device controlled by a preset sequence, a subsequent test flow is performed.
S200, receiving the image information of the output end of the FA connector when the optical signals are sent to the channels of the input end of the FA connector;
in step S200, in order to acquire an output channel corresponding to the FA connector when transmitting an optical signal to the current input channel of the FA connector. Therefore, when the optical signal is sent to the input end channel of the FA connector each time, the output end channel corresponding to the current input end channel can be obtained by acquiring the output end image of the FA connector according to the position information of the light spot in the output end image.
S300, after receiving the output end image information corresponding to all input end channels of the FA connector, sorting and fusing all the output end image information to obtain a fused image;
in step S300, the output image information corresponding to all the input channels of the FA connector is received, namely: according to the preset sequence in step S100, each time an optical signal is sent to the current input end channel of the FA connector, the corresponding output end image information is obtained, and after all the input end channels of the FA connector are traversed according to the preset sequence, all the corresponding output end image information is obtained. In step S300, after all the received output image information is ordered according to the receiving order, all the output image information is fused according to the receiving order to obtain a fused image.
S400, acquiring a test polarity relation of the FA connector according to the fusion image, comparing the test polarity relation with a preset polarity relation, and judging whether the polarity of the FA connector meets the requirement.
In the step S400, according to the ordering of the image information of the plurality of output ends from left to right in the fused image, and by combining the manner of transmitting the optical signals to the input end channels of the FA connector in the preset sequence in the step S100, the test polarity relationship of the FA connector can be obtained, and the obtained test polarity relationship is compared with the input preset polarity relationship, so as to obtain whether the polarity of the FA connector meets the requirement.
In this embodiment, an FA connector polarity test method is executed in an intelligent device, for example, by installing a corresponding software in a computer, and the computer loaded with the software is used to execute the FA connector polarity test method. The method comprises the steps of sending optical signals to each input end channel of the FA connector through an automatic control light source device, obtaining and processing image information of the output end of the FA connector, obtaining the test polarity relation of the FA connector tested at present, and finally, comparing the test polarity relation with the preset polarity relation to quickly and accurately obtain whether the polarity of the FA connector tested at present meets the requirements or not.
Referring to FIG. 2, in some embodiments, to reduce data processing and quickly determine that the currently tested FA connector belongs to an abnormal product. The invention relates to a method for testing the polarity of an FA connector, which comprises the following steps:
s210, judging whether a light spot exists in the received current image information of the output end or not when the image information of the output end of one FA connector is received;
if yes, executing the steps of:
s220, after the current output end image information is stored, continuing to receive the next output end image information until receiving the output end image information corresponding to all input end channels of the FA connector;
otherwise, the steps are executed:
s230, controlling the light source device to stop sending the optical signal to the next input end channel of the FA connector, and feeding back the abnormal information of the FA connector product.
In this embodiment, since each input channel of the FA connector corresponds to one output channel one by one, when an optical signal is sent to a certain input channel of the FA connector, the image information of the output of the FA connector is collected, and therefore, a light spot can be necessarily observed from the image information of the output. Therefore, in order to save test time and test cost, when no light spot exists in the received image information of a certain output end, the polarity abnormality of the currently tested FA connector is indicated, at this time, the light source device is controlled to stop sending the light signal to the next input end channel of the FA connector, and feedback the abnormal information of the FA connector product, so as to inform the testers that the polarity of the FA connector does not meet the requirement. If the received image information of each output end has light spots, the input end channels of the FA connector can smoothly transmit optical signals, at the moment, after all the input end channels of the FA connector are received, all the received image information of the output ends are sequenced and integrated according to the receiving sequence to obtain a fusion image for processing of the next step.
In some embodiments, for convenience of data processing, the preset sequence in step S100 is the numbering sequence of the input channels of the FA connector. The serial numbers of the input end channels of the FA connectors are marked when each FA connector is manufactured, and optical signals are sent to the input end channels of the FA connectors according to the serial numbers of the input end channels of the FA connectors, so that simplification of a control program of the light emitting sequence of the light source device is facilitated.
In some embodiments, to further reduce data processing, and ease of control procedures when performing FA connector polarity testing. In this embodiment, each input end channel of the FA connector is connected to each light source channel of the light source device in a one-to-one correspondence manner, and the number of each input end channel of the FA connector connected correspondingly is identical to the number of each light source channel of the light source device. For example, in some embodiments, the FA connector is a 4-core FA connector, the light source device is a multi-path light source device (at least 4 paths), the input channel with the number 1 of the input channels of the FA connector is connected with the light source channel with the number 1 of the multi-path light source device, and so on, the input channel with the number 4 of the input channels of the FA connector is connected with the light source channel with the number 4 of the multi-path light source device, and then the light source device is controlled to send the optical signals according to the number sequence of the light source channels, that is, the polarity test of the FA connector is performed according to the number sequence of the input channels of the FA connector. Further, when receiving the output image information of the FA connector, the first output image information received corresponds to the input channel with the input channel number 1 of the FA connector, for example: the preset sequence of transmitting the optical signals to the FA connector is: 1,2,3,4, the received 4 pieces of output end image information in this embodiment are: the received first output end image information is the output end image information of the FA connector when the optical signal is sent to the first input end channel of the FA connector; the received second output end image information is the output end image information of the FA connector when the optical signal is sent to the second input end channel of the FA connector; the received third output end image information is the output end image information of the FA connector when the optical signal is sent to the third input end channel of the FA connector; and the received image information of the fourth output end is the image information of the output end of the FA connector when the optical signal is sent to the FA connector.
Referring to fig. 3, taking the preset polarity relationships of the 4-core FA connector as 1-4,2-2,3-3 and 4-1 in the above embodiments as an example, in some embodiments, the output end image information received by the 4-core FA connector is ordered, the received first output end image information is taken as a reference image (that is, corresponds to the output end image information when the optical signal is sent to the first input end channel of the FA connector), and image fusion is performed according to the receiving order of each output end image information to obtain a fused image, where after taking the first output end image information as the reference image, a light spot in the subsequently received output end image information is extracted, and the light spot is inserted into the reference image according to the position of the light spot in the output end image information. If the number of the light spots in the obtained fusion image is consistent with the number of the output end channels of the FA connector, according to the relative positions of the light spots in the image information of each output end and the light spots in the reference image, the corresponding relation between the input end channels of the FA connector and the output end channels is obtained by combining a preset sequence (namely the serial numbers of the input end channels of the FA connector: 1,2,3 and 4), the corresponding relation is a test polarity relation, the test polarity relation is obtained, and the test polarity relation is 1-4,2-2,3-3 and 4-1, so that the test polarity relation of the FA connector is consistent with the preset polarity relation, and the FA connector meets the requirements. If the number of light spots in the fusion image is inconsistent with the number of channels at the output end of the FA connector, or the obtained test polarity relationship is inconsistent with the preset polarity relationship, the polarity relationship of the FA connector is not satisfied. In this embodiment, only a 4-core FA connector is taken as an example, and it is obvious that FA connectors with other channels can also complete the polarity test in the same way, and the polarity test is also included in the protection scope of the present application. In addition, in order to prevent the situation that the light spots are too large or too small in display in the image information of the output end, so that the light spots are crossed or too large in gap during image fusion, the power of the light source device can be adaptively adjusted according to the light spot size in the image information of the output end.
In addition, it should be noted that, in the present application, the input end channels (input ends) and the output end channels (output ends) divided by the FA connector are all for better describing the implementation principle and implementation process of the present application, and the input end channels are not meant to be limited to only input signals but not output signals, and the output end channels are not meant to only output signals but not input signals.
