In the current switch equipment, when the equipment is in working state, it is affected by the environment, such as temperature and humidity.

It is particularly important to design a model to monitor the abnormality of the clock crystal. In the past, it was necessary to manually locate and measure the abnormality of the clock crystal signal, which was a cumbersome process, and the location wasted time, and the problem was not solved in time. As can be seen from the above, in the process of signal anomaly detection, how to improve the accuracy of signal anomaly detection, increase the efficiency of signal anomaly detection, and reduce the time of signal anomaly detection are problems to be solved in this field.

[0044] See also Figure 1 As shown, the embodiment of the present invention discloses a signal anomaly detection method, which may specifically include:

[0045] Step S11: Acquire a crystal clock signal to be detected, and perform clock signal processing on the crystal clock signal to be detected to obtain phase information of the processed clock signal.

[0046] In this embodiment, before obtaining the crystal clock signal to be detected, the method further includes: obtaining normal historical clock crystal clock signal information; and determining a historical variable threshold value based on the historical clock crystal clock signal information.

[0047] The present application is applied to an alarm model for detecting abnormal clock crystal signals of a switch. A large amount of historical normal data of clock crystals collected from switch devices is used to determine the historical variable threshold value, and then clock signal processing is performed on the crystal clock signal to be detected. The specific processing process is: determining the phase lock cycle according to business needs; using a preset phase-locked loop integrated circuit and according to the phase lock cycle, phase locking is performed on the crystal clock signal to be detected, and an extraction operation is performed at the same time to obtain clock signal phase information.

[0048] Step S12: Calculate the phase information of the clock signal using a preset phase accumulator to obtain a phase jump variable.

[0051] It can be understood that the present application uses a large amount of historical normal data of clock crystals collected from switch devices to determine the historical variable threshold value, and then obtains the crystal clock signal to be detected, and uses a preset phase-locked loop integrated circuit and according to the phase lock cycle to phase lock the crystal clock signal to be detected, and performs an extraction operation at the same time to obtain the clock signal phase information, and uses the phase accumulator in the preset phase accumulator to add the clock signal phase information to obtain the sum value; finds the corresponding sampling point number through the lookup table in the preset phase accumulator, and then outputs the corresponding waveform value according to the number, and uses a filter to obtain a smooth waveform, and then performs a phase jump variable calculation to obtain a phase jump variable, and determines whether the phase jump variable is greater than the preset The historical variable threshold value, if the phase jump variable is greater than the preset historical variable threshold value, the crystal clock signal to be detected is determined to be abnormal, and then the abnormal information of the crystal clock signal to be detected is saved locally, abnormal alarm information is created, and the abnormal alarm information is sent to the inspector for clock alarm, so that after receiving the abnormal alarm information, the inspector determines the abnormal clock crystal position according to the abnormal alarm information, and detects the abnormal clock crystal according to the abnormal clock crystal position; if the phase jump variable is less than the preset historical variable threshold value, the crystal clock signal to be detected is determined to be normal, and the crystal clock signal information to be detected is used as the normal historical clock crystal clock signal information to obtain a new historical variable threshold value. The present invention uses the phase-locked loop principle to perform clock signal phase locking at fixed intervals and extract clock signals at the same time. The phase jump variable is compared with the set variable threshold and a judgment is made at the same time. If the correct data is determined, it will be continuously integrated into the historical data to provide a basis for the predetermined threshold. If the set threshold value is exceeded, the abnormal data is determined, a clock alarm will be made in time, and abnormal information will be stored. At the same time, an alarm signal is issued, and the staff can check the switch equipment and locate the abnormal clock crystal position in the first time. The present invention can regularly monitor the signal conditions of each clock crystal in the switch equipment, and quickly determine the abnormal crystal clock position, and immediately prompt an alarm to avoid serious consequences. In addition, the present invention can not only be used for switch clock crystal monitoring and alarm, but also for a variety of equipment such as servers. Through this model, the abnormal crystal clock signal can be quickly determined, and the location and processing can be carried out in time, without investing a lot of time for technicians to locate one by one. The crystal clock information can be obtained simply and quickly, so as to make a quick response to abnormal situations. Therefore, the present invention designs a clock crystal signal alarm model.

The phase jump variable of the crystal clock signal is compared with a preset threshold, and the clock signal exceeding the threshold is alarmed. With the rapid development of deep learning, in switch equipment, any abnormality of a clock crystal will have a serious impact on the clock signal.

The phase jump variable is greater than the preset historical variable threshold value, and the crystal clock signal to be detected is determined to be abnormal. Then, the abnormal information of the crystal clock signal to be detected is saved locally, abnormal alarm information is created, and the abnormal alarm information is sent to the inspector for clock alarm, so that after receiving the abnormal alarm information, the inspector determines the abnormal clock crystal position according to the abnormal alarm information, and detects the abnormal clock crystal according to the abnormal clock crystal position; if the phase jump variable is less than the preset historical variable threshold value, the crystal clock signal to be detected is determined to be normal, and the crystal clock signal information to be detected is used as the normal historical clock crystal clock signal information to obtain a new historical variable threshold value. The present invention utilizes the phase-locked loop principle to perform clock signal phase locking at fixed intervals and extract clock signals at the same time. The phase jump variable is compared with the set variable threshold, and a judgment is made at the same time. If the correct data is determined, it will be continuously integrated into the historical data to provide a basis for the predetermined threshold. If the set threshold value is exceeded, the abnormal data is determined, a clock alarm will be made in time, and abnormal information will be stored. At the same time, an alarm signal is issued, and the staff can check the switch equipment and locate the abnormal clock crystal position in the first time.

The crystal clock information can be obtained simply and quickly, so as to make a quick response to abnormal situations. Therefore, the present invention designs a clock crystal signal alarm model.

[0063] In this embodiment, a crystal clock signal to be detected is obtained, and clock signal processing is performed on the crystal clock signal to be detected to obtain phase information of the processed clock signal; the phase information of the clock signal is calculated using a preset phase accumulator to obtain a phase jump variable; it is determined whether the phase jump variable is greater than a preset historical variable threshold value, and if the phase jump variable is greater than the preset historical variable threshold value, the crystal clock signal to be detected is determined to be abnormal.
