Description
Technical Field
The present application relates to the field of electromagnetic compatibility technologies, and in particular, to a method and a system for troubleshooting electromagnetic radiation problems of an external interface.
Background
The electromagnetic radiation interference means that an interference signal generated by an electronic device is coupled through space to transmit the interference signal to another electric network or the electronic device. When judging whether the information storage equipment meets the requirements of the national standard GB9254 radio disturbance limit and measurement method of information technology equipment and the limit values above 1GHz and below 1GHz, the electromagnetic radiation needs to be tested in a 10m semi-anechoic chamber, and then whether the information storage equipment can meet the requirements of the national standard GB9254 is judged according to the test result fed back by the receiver.
When the tested system tests electromagnetic radiation in a 10m half-anechoic chamber, if the test result does not meet the requirement of GB9254, an electromagnetic compatibility engineer is required to perform problem troubleshooting on the tested system.
At present, a method for checking an electromagnetic radiation problem of an external interface of information storage equipment generally comprises the following steps: and analyzing the peripheral interfaces of the information storage equipment to be tested in the sequence from outside to inside. Specifically, the electromagnetic compatibility engineer needs to manually pull out the interface cables one by one to disconnect the communication state of the interfaces, or manually connect the interface cables to connect the communication state of the interfaces, thereby checking each interface one by one. Especially, when hundreds of external interfaces are arranged in a tested system, cables need to be plugged in and pulled out one by one to confirm whether a test result exceeds a limit value specified by the national standard GB9254 due to one of the interfaces.
However, in the existing electromagnetic radiation problem troubleshooting method, because cables are plugged and pulled one by one manually, troubleshooting efficiency is too low, and errors are easily generated by manual operation, such as: some of the tests of the interface are missed, resulting in a less accurate troubleshooting. Moreover, for some tested systems which do not support hot plugging, the initial state of the test can be changed after the cable is pulled out every time, and the tested systems need to be restarted to recover the initial test condition, so that more time is occupied, and the troubleshooting efficiency is further influenced.

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For a better understanding of the present application, embodiments of the present application are explained in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for troubleshooting an electromagnetic radiation problem of an external interface according to an embodiment of the present application. As can be seen from fig. 1, the method for troubleshooting the electromagnetic radiation problem of the external interface in the embodiment mainly includes the following steps:
s1: and checking whether the electromagnetic radiation of the equipment to be tested exceeds a limit value for the external interface according to the electromagnetic radiation energy change of the external interface in the equipment to be tested.
Specifically, step S1 further includes:
s11: and acquiring first electromagnetic radiation energy, wherein the first electromagnetic radiation energy is the electromagnetic radiation energy of the equipment to be tested before all external interfaces are disconnected from the communication connection of the receiver.
In an experiment for measuring the radio disturbance limit value of information technology equipment, a receiver is generally adopted to measure electromagnetic radiation energy, and the receiver of a 10m half anechoic chamber can display the electromagnetic radiation energy of a corresponding frequency point exceeding the limit requirement of the national standard GB 9254. In this embodiment, the electromagnetic radiation energy may be obtained by measuring with a receiver and then feeding back to the troubleshooting device.
S12: and disconnecting the communication connection between all external interfaces on the equipment to be tested and the receiver according to the acquired first closing command.
By closing all external interfaces on the device to be tested, the communication connection between all the interfaces on the device to be tested and the receiver can be disconnected.
S13: and acquiring second electromagnetic radiation energy, wherein the second electromagnetic radiation energy is the electromagnetic radiation energy of the equipment to be tested after all external interfaces are disconnected from the communication connection of the receiver.
S14: and judging whether the second electromagnetic radiation energy is smaller than the first electromagnetic radiation energy.
S15: if yes, the external interface is judged to cause the electromagnetic radiation to exceed the limit value.
And when the second electromagnetic radiation energy is smaller than the first electromagnetic radiation energy, determining that the external interface causes the electromagnetic radiation of the device to be tested to exceed the limit value. Generally, if the external interface causes electromagnetic radiation exceeding the limit value, after all the external interfaces on the device under test are disconnected from the receiver, the electromagnetic radiation energy of the device under test measured by the receiver will be reduced, or even finally disappear, that is, the second electromagnetic radiation energy will be smaller than the first electromagnetic radiation energy. Therefore, whether the external interface fault occurs can be effectively judged by comparing the second electromagnetic radiation energy with the first electromagnetic radiation energy.
If the second electromagnetic radiation energy is equal to the first electromagnetic radiation energy, it is determined that the external interface does not cause electromagnetic radiation to exceed the limit. Obviously, there is no case where the second electromagnetic radiation energy is greater than the first electromagnetic radiation energy.
As can be seen from the above steps S11-S15, in this embodiment, by obtaining the electromagnetic radiation energies before and after disconnecting the communication between all external interfaces on the device under test and the receiver, and comparing the electromagnetic radiation energies before and after disconnection, and by comparing the electromagnetic radiation energies before and after disconnection, it can be determined whether the external interfaces cause the electromagnetic radiation of the device under test to exceed the limit value.

S2: when the external interface causes the electromagnetic radiation of the equipment to be tested to exceed the limit value, the external interface with a fault is determined by sequentially controlling the communication states of the external interface and the receiver.
After it is determined that the external interface causes electromagnetic radiation of the device under test to exceed the limit value through step S1, it is further determined which specific external interfaces are faulty interfaces among all the external interfaces. Specifically, step S2 includes the following process:
s21: and starting communication connection between all external interfaces on the equipment to be tested and the receiver according to the acquired first starting command.
By opening all the external interfaces on the device to be tested, the communication connection between all the external interfaces on the device to be tested and the receiver can be opened.
S22: and according to the obtained second closing command, sequentially disconnecting the communication connection between any external interface on the equipment to be tested and the receiver.
In the implementation, the serial numbers can be carried out on each external interface on the equipment to be tested, the serial numbers are added into the second closing command, and the communication state between each external interface and the receiver can be accurately controlled through the second closing command with the serial numbers of the external interfaces.
S23: and acquiring third electromagnetic radiation energy, wherein the third electromagnetic radiation energy is the electromagnetic radiation energy of the equipment to be tested after the communication connection between any external interface and the receiver is disconnected.
S24: and judging whether the third electromagnetic radiation energy is smaller than the first electromagnetic radiation energy.
S25: and if so, determining that the external interface matched with the third electromagnetic radiation energy is a fault interface.
As can be seen from the above steps S21-S25, in this embodiment, each external interface on the device under test is sequentially closed, and the electromagnetic radiation energy after the current external interface is closed is obtained, that is: and comparing the third electromagnetic radiation energy with the first electromagnetic radiation energy to judge whether the current external interface is a fault interface.
When the third electromagnetic radiation energy is smaller than the first electromagnetic radiation energy, it is determined that the external interface matched with the third electromagnetic radiation energy causes the electromagnetic radiation of the device under test to exceed the limit value, that is, the external interface matched with the third electromagnetic radiation energy is a fault interface. Generally, if the external interface matched with the third electromagnetic radiation energy causes electromagnetic radiation exceeding the limit value, after the communication connection between the external interface on the device to be tested and the receiver is disconnected, the electromagnetic radiation energy of the device to be tested measured by the receiver will be reduced or even finally disappear, that is, the third electromagnetic radiation energy will be smaller than the first electromagnetic radiation energy. Therefore, by comparing the third electromagnetic radiation energy with the first electromagnetic radiation energy, whether the external interface matched with the third electromagnetic radiation energy has a fault can be effectively judged.
If the third electromagnetic radiation energy is equal to the first electromagnetic radiation energy, it is determined that an external interface not matched by the third electromagnetic radiation energy results in electromagnetic radiation exceeding a limit. Obviously, there is no case where the third electromagnetic radiation energy is greater than the first electromagnetic radiation energy.
