Description
Technical Field
The present invention relates to the field of computers, and in particular, to a method, an apparatus, a device, and a medium for testing radiation interference resistance of a server.
Background
Along with the continuous acceleration of the progress of the informatization age, various IT products are continuously updated and developed. Especially, the cloud era comes, and the performance requirements on the server are higher and higher. The demand for high performance, high-profile servers is increasing. With the continuous improvement of server performance, high-power consumption and high-power servers are becoming the main stream of the server market. As conventional computing servers are increasingly used, there is an increasing need for servers in the large telecommunications and internet industries. For example, the telecommunications industry builds a large-scale telecommunications room, and the application environment, personnel operation, etc. of the room present a greater challenge to the surge anti-interference capability of the server. In the electromagnetic compatibility (Electro Magnetic Compatibility, abbreviated as EMC) standard, electromagnetic emission and electromagnetic tolerance are divided into two parts. Wherein electromagnetic resistance is also called electromagnetic anti-interference. The electromagnetic environment of the current server is very complex, and the radiation interference in the machine room has great influence on the normal operation of the server. Therefore, the electromagnetic radiation anti-interference capability of the server often determines whether the server can normally work in a complex electromagnetic interference environment, and is an important measurement index of the performance of the server.
At present, the traditional server radiation immunity test frequency selection modes include the following two modes: the first is to set a frequency band, for example, in a continuous frequency band of 80-1000MHz, and the like, and the frequency of the actually tested radiation immunity is generally increased by 1% from 80MHz and the residence time is 3s, and the frequency comprises: 80MHz,88MHz, 96.8MHz, etc. The second is to set fixed frequency points, for example, part of special frequency points are specified in CISPR35 electromagnetic compatibility standard, including 1800MHz, 2600MHz, 3500MHz, 5000MHz, etc., and the fixed frequency points can be resided for 3s during testing to apply radiation interference. However, the choice of test frequency values for radiation immunity of conventional servers has great limitations, e.g. in the frequency range between 80-88MHz, in fact many frequency points do not impose radiation interference tests. If a strong radiation interference signal exists in the machine room environment where the server is located at the moment, serious interference and even damage to the normal operation of the server can be caused. In addition, because a plurality of servers with the same model are generally placed in the same cabinet, serious radiation interference is possibly generated between the servers, and the frequency points of the interference are irregular and can be determined through radiation test. It can be seen that the conventional server radiation immunity test cannot accurately and efficiently verify all frequency points which may cause serious radiation disturbance, so that improvement is needed.

In some implementations, the step of determining the test frequency based on the crystal oscillator clock frequency further includes:

counting the model numbers of a plurality of servers in a test environment;
selecting one server from the servers of each model as a target server;
and collecting radiation signals generated in the operation process of the target server by using radiation signal collecting equipment.
In some embodiments, the signal type includes a narrowband signal waveform and a wideband signal waveform, the step 103 of determining the test frequency based on the signal type and the radiated signal includes:

and obtaining a plurality of test frequencies in the frequency segment by taking ten percent of the previous test frequency added each time as a step length from the first preset frequency.
In some embodiments, the method further comprises:
a plurality of preset fixed frequencies are selected as test frequencies.
For example, the specific frequencies may refer to specific frequency points of the part specified in the CISPR35 electromagnetic compatibility standard, and the preset fixed frequency may be 1800MHz, 2600MHz, 3500MHz, 5000MHz, etc.
In some embodiments, for the sake of understanding the technical solution of the present invention, please refer to fig. 2, and it is not assumed that a plurality of servers of the same type are placed on a certain cabinet of a server room and are respectively denoted as servers 1 to 6, and in an actual working environment, each server generates electromagnetic radiation to the outside, and each server receives radiation emission interference from other servers. For example, when the server 1 is operating normally, it will interfere with the radiation emissions generated by the external environment, and the remaining 5 prototypes will be in exactly this interfering electromagnetic field. At this time, interference by electromagnetic emission of prototype 1 is necessarily received. When the interference value reaches a certain degree, the influence of downtime, performance reduction and the like on the other 5 prototypes is caused; in order to solve the above problems, the method for testing the radiation interference resistance of the server on the server cabinet mainly comprises the following two parts:
a first part employing a conventional radiation immunity test, wherein the frequency is fixed; for example, the frequency band is set to 80-1000MHz, and whether the servers 1-6 can work normally or not is tested under the signal interference of 80MHz,88MHz and 96.8MHz … … respectively.
And the second part is used for measuring and finding out the worst frequency value of the server body when radiation is emitted, and taking the worst frequency value as the test frequency of the subsequent radiation immunity test after recording, and taking the clock frequency of the server as the other supplementary test frequency of the radiation immunity frequency, wherein the specific implementation mode is as follows:
and step 1, performing radiation emission test on the server 1, and confirming test data.
Step 2, as shown in fig. 3A, the narrowband waveform signal with higher signal intensity is directly used as a test frequency value of radiation immunity, immunity test is carried out, and whether the server 2-5 can work normally is judged;
and 3, setting the left, middle and right frequency points of the broadband waveform signal with stronger signals as test frequency values of radiation immunity as shown in fig. 3B, performing immunity test, and judging whether the server 2-5 can work normally.
And 4, taking the clock frequency of the crystal oscillator of the server 1 and the frequency multiplication thereof as the test frequency of radiation immunity. For example, 50MHz clock frequency, 50MHz,100MHz,150MHz … … are selected until it is 1000MHz or less, and an immunity test is performed to determine whether the server 2-server 5 can operate normally.
It should be noted that, since each server generates electromagnetic interference to the outside, the mutual interference between the servers must be considered when the radiation immunity test is performed; the radiation signal infection of the servers with the same model is basically the same, so that if only one signal server in the test environment is needed, only one server is selected, and more important frequency point recharging tests are found through the steps 1 to 4. If there are multiple types, the radiation interference generated by each type of server is considered, namely, one server is selected as the execution object of the steps 1 to 4 to find more important frequency points.
The method for testing the radiation anti-interference degree of the server has the following beneficial technical effects: the frequency value specified by the regulation is preferentially used as the test frequency of the radiation immunity; and carrying out radiation emission test on the server, and taking a frequency point with a strong radiation emission value signal as a frequency point of radiation immunity test according to test data. According to the clock frequency of the server crystal oscillator, taking the frequency multiplication of the clock frequency as the test frequency of radiation immunity; the method has the advantages that the method can more efficiently and accurately select the test frequency value of the radiation immunity of the server, ensure that the server can meet the requirement of the radiation immunity, and ensure that the server can normally operate without being influenced by electromagnetic radiation under complex electromagnetic environments such as a machine room.
