Description
Technical Field

Background
The general server performs self-checking on the BIOS in the starting process, and if the memory fails, a sound alarm is sent, for example, 2 short indicates that the memory ECC is checked wrongly, 3 short indicates that the system basic memory is checked unsuccessfully, 8 short indicates that the memory is failed, and the like.
However, the memory fault alarm only works when the system is powered on for self-checking, if the memory fault occurs after the system enters, no alarm sound is generated, and a tester cannot know that the memory fault occurs immediately.
In addition, the existing fault detection method can only detect that the memory has faults, but a tester cannot judge whether the fault reason is the problem of the memory or the problem of the memory slot according to the alarm information. The common further detection method is to power off the machine, replace the memory bank without fault for testing, if still reporting the error, indicate that the memory slot is faulty; if no error is reported, the memory is a fault of the memory, and the memory bank needs to be replaced. This detection method requires termination of the running program, restarting of the system, time and labor consuming, and inefficient.

Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily limit the invention.
As shown in fig. 1, a first embodiment of the present invention discloses a memory fault alarm device 100, which includes an MCU101, and a voice alarm module 102, an LED103 and a distance detection module 104 electrically connected to the MCU 101;
the MCU101 receives the memory error signal and the distance sensing signal of the distance detection module 104 from the test server, and sends control signals to the voice alarm module 102 and the LED 103.
Specifically, when a CPU or a BIOS of the test server reads and writes the memory, addressing is first required, and at this time, the capacitor discharges to generate a potential change, and charges are transferred to the IO line, which causes the potential of the line to change. If the CPU or the BIOS finds that the line potential does not change at this time, it determines that the memory at the location has a fault, and sends a memory error signal to the memory fault alarm device 100 of this embodiment. The specific mode of generating the memory error signal is that the CPU processes the signal and transmits the signal to the MCU101 of the memory fault alarm device 100 of this embodiment through the FPGA chip.
Specifically, after receiving the memory error signal sent by the test server, the MCU101 controls the LED103 to light up, which indicates that the memory has a fault, and at this time, the voice alarm module 102 does not act.
Meanwhile, the distance detection module 104 detects whether the memory slot deviates from the original position. When the memory slot is inclined or the pin lines in the memory slot are contacted together to cause short circuit, the contact between the memory bank and the mainboard is poor, and the mainboard cannot identify the memory bank. When the memory slot inclines, the distance sensor of the distance detection module 104 detects that the memory slot deviates from the original position, the distance sensor sends an analog signal, the analog signal is processed into a digital signal by the sensor signal processing circuit and transmitted to the MCU101, the MCU101 controls the voice alarm module 102 to give out a sound alarm after receiving the signal, and at the moment, the LED103 and the voice alarm module 102 simultaneously give out an alarm signal.
Therefore, the tester can judge the fault reason of the memory according to the light signal and the sound signal. When a light alarm signal and a sound alarm signal are available, the fault reason is the fault of the memory bank; when the light alarm signal and the sound alarm signal exist at the same time, the fault reason is the fault of the memory slot.
Specifically, the distance detection module 104 is further provided with an LCD display screen, and the distance sensor analog signal of the distance detection module 104 transmits the detection information to the LCD display screen through the signal processing circuit, so that the LCD display screen displays a number greater than 0. When the light alarm signal and the sound alarm signal exist at the same time, the tester confirms that the fault reason is the memory slot fault, at the moment, the tester reads the number of the LCD display screen, and when the number of the LCD display screen is larger than 0, the memory slot fault is the inclination of the memory slot; when the number of the LCD screen is 0, the failure of the memory slot is indicated as short circuit of the pin line of the memory slot and other reasons.
Preferably, the model of the MCU is EN8P1100 IRC; the distance sensor is RS 232; the voice alarm module chip is AC3L 710.
Based on the memory fault alarm device in the first embodiment, a second embodiment is provided as shown in fig. 2 for the memory fault test of the multi-memory slot server.
The distance detection module of the memory fault alarm device shown in fig. 2 includes distance sensors and LCD display screens, and the numbers of the distance sensors, the LCD display screens and the LEDs are all consistent with the number of the memory slots of the test server, and are respectively used for acquiring the distance states of the corresponding memory slots and displaying the fault states of the corresponding memory slots.
When the memory fault alarm device sends out an alarm signal, a tester can accurately find out the memory position with a fault according to the memory slot corresponding to the LED.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, the scope of the present invention is not limited thereto. Various modifications and alterations will occur to those skilled in the art based on the foregoing description. And are neither required nor exhaustive of all embodiments. On the basis of the technical scheme of the utility model, various modifications or deformations that technical personnel in the field need not pay out creative work and can make still are within the protection scope of the utility model.
