In the prior art, the abnormality detection is usually performed on the startup process of the motherboard by a motherboard diagnostic card (i.e., motherboard fault diagnostic card), specifically, the detection result of a BIOS (Basic Input Output System ) program in the motherboard is utilized, the result is displayed in a code form, and the fault location can be quickly determined by combining with the meaning of the code.
However, the above fault diagnosis method only can roughly learn on which interface the fault occurs, and for the interface, it is impossible to determine in which functional component in the interface the fault occurs, and it is also impossible to determine the specific fault type in the interface, and the fault detection effect is poor.

The control module is specifically configured to obtain, through the interface communication module, a real-time input voltage of at least one voltage input pin in the motherboard interface, and compare the real-time input voltage with a corresponding standard input voltage to determine whether a first cold joint fault pin exists in the at least one voltage input pin, where the first cold joint fault pin is related to overvoltage, undervoltage, or voltage oscillation. Through the detection to the first rosin joint trouble pin in the mainboard interface, avoided voltage oscillation or the damage of too high voltage to external equipment, also prevented the too low effective operation that can't support external equipment of voltage, promoted the security performance of mainboard interface.

The change of the brightness, the color and the working mode of the indicator lamp not only intuitively reflects the overvoltage, the undervoltage and the voltage oscillation phenomena of the voltage input pins in the main board interface, but also ensures that the brightness adjustment and the flicker interval time of the indicator lamp are configured according to preset fixed values, so that the damage to the indicator lamp caused by the overlarge brightness increase when the undervoltage value is smaller and the overlong flicker interval time when the voltage oscillation frequency is lower are avoided, and operators cannot timely sense the faults.

Compared with the existing mainboard diagnostic card, the embodiment of the invention can only determine the interface where the fault is located, not only realize the detection of the data transmission fault in the mainboard interface, but also determine that the transmission fault is derived from a specific data transmission pin, and further improve the fault detection precision of the mainboard interface.

The method ensures the accuracy of the detection result and expands the detection range of the pin cold solder fault while realizing the cold solder fault detection of the data transmission pins in the main board interface.
The control module is specifically further configured to determine that the transmission failure of the data transmission pin is related to the cold joint failure of the data transmission pin if no cold joint failure is detected in the voltage input pins of the current motherboard interface and no transmission failure is detected in the data transmission pins of the current motherboard interface. Through the detection of the cold joint fault of the voltage input pin in the main board interface and the detection of the transmission fault of the data transmission pin, the detection of the cold joint fault of the data transmission pin is realized, and the accuracy of the detection result is further ensured.

It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1A is a schematic structural diagram of a fault detection device according to an embodiment of the present invention, where the fault detection device includes a control module 100, a storage module 200, and at least one interface communication module 300, and the interface communication module 300 is connected to a corresponding motherboard interface in a device to be tested.
Since the motherboard of the electronic device generally includes a plurality of different types of interfaces, for example, a PCI (PERIPHERAL COMPONENT INTERCONNECTION, peripheral component interconnect) interface (i.e., PCI slot), a memory slot, a PCIe (PCI-Express, peripheral component interconnect extension) interface, an industry standard architecture bus extension (Industrial Standard Architecture, ISA) slot, etc., the fault detection device may also include a plurality of interface communication modules 300, where the architecture of each interface communication module 300 matches the architecture of a corresponding interface on the motherboard, so that the fault detection device may connect the corresponding interface on the motherboard through each interface communication module 300 when performing fault detection, and optionally, in the embodiment of the present invention, the types, architectures, and numbers of the motherboard interface and the interface communication modules 300 are not specifically limited.
The control module 100 is connected to the storage module 200 and the at least one interface communication module 300, and is configured to perform a pin cold joint test on at least one motherboard interface through the at least one interface communication module 300 to detect whether a cold joint fault exists in a voltage input pin of the at least one motherboard interface, and perform a performance test and/or a pressure test on the at least one motherboard interface through the storage module 200 and the at least one interface communication module 300 to detect whether a transmission fault exists in the at least one motherboard interface. Each interface on the mainboard is provided with a fixed pin structure, and each pin has a fixed function, for example, an A2 pin in the PCI interface is used for inputting 12V voltage, an A5 pin is used for inputting 5V voltage, and an A27 pin is used for inputting 3.3V voltage, so that whether voltage input signals exist on each voltage input pin can be detected respectively.
Specifically, after the fault detection device is connected with the motherboard of the device to be tested, when the motherboard is in an inactive state, the fault detection device cannot detect an input voltage signal from each voltage input pin of the motherboard interface through the interface communication module 300, when the motherboard is started, the fault detection device can detect an input voltage signal from each voltage input pin of the motherboard interface through the interface communication module 300, therefore, when the fault detection device acquires an input voltage provided by the motherboard through any voltage input pin, the fault detection device sends a first test signal to the motherboard through the interface communication module 300, if a feedback signal of the motherboard for the first test signal is acquired, the motherboard is indicated to be started, the input voltage acquired by the fault detection device is a normal voltage signal after the motherboard is started, and if no voltage input signal is detected on one or more voltage input pins, the voltage input pins are indicated to be in an open circuit state due to the existence of a cold solder fault.
If the feedback signal of the main board for the first test signal is not obtained, the main board is not started at the moment, the input voltage obtained by the fault detection device is abnormal power supply caused by short circuit, and if the voltage input signal is detected on one or more voltage input pins, the voltage input pins are in a short circuit state due to the existence of a cold joint fault, and therefore the cold joint detection of the voltage input pins is realized through circuit breaking detection and short circuit detection.
Optionally, in the embodiment of the present invention, the control module 100 is specifically configured to obtain, through the interface communication module 300, a real-time input voltage of at least one voltage input pin in the motherboard interface, and compare the real-time input voltage with a corresponding standard input voltage to determine whether a first cold joint fault pin exists in the at least one voltage input pin, where the first cold joint fault pin is related to overvoltage, undervoltage, or voltage oscillation. The standard input voltage is the input voltage of the current voltage input pin in the normal working state, for example, in the above technical scheme, the A2 pin of the PCI interface is used to provide the 12V input voltage, and the standard input voltage is 12V.
If the real-time input voltage of the current voltage input pin is smaller than the corresponding standard input voltage within the preset detection time, indicating that the undervoltage phenomenon exists in the current voltage input pin; if the real-time input voltage is smaller than the standard input voltage in part of time and the real-time input voltage is larger than the standard input voltage in part of time in the preset detection time, the voltage oscillation phenomenon of the current voltage input pin is indicated, the current voltage input pin is a cold joint fault pin (namely a first cold joint fault pin), and the damage of voltage oscillation or overhigh voltage to external equipment is avoided through the detection of the first cold joint fault pin in the main board interface, the effective operation that the voltage is too low to support the external equipment is prevented, and the safety performance of the main board interface is improved.
As shown in fig. 1B, optionally, in the embodiment of the present invention, the fault detection device further includes at least one indicator lamp 400, and the control module 100 is connected to the at least one indicator lamp 400 and further configured to change the brightness and/or color of the corresponding indicator lamp 400 if the first cold joint fault pin is related to an overvoltage or an undervoltage, and set the working mode of the corresponding indicator lamp 400 to flash if the first cold joint fault pin is related to a voltage oscillation. The fault detection device may include only one indicator lamp 400, and when at least one first cold joint fault pin exists, a prompt is sent to a detection person by changing the brightness, the color or the working mode of the indicator lamp 400, wherein the working mode includes normal on, normal off and flashing, the fault detection device may also include a plurality of indicator lamps 400, and different indicator lamps 400 are matched with the number ordering results of the voltage input pins one by one according to the number sequence, for example, the number 1 indicator lamp 400 is matched with the voltage input pin with the forefront number, and the voltage input pin may be an A2 pin, an A5 pin or any other pin due to different pin distribution of different interfaces.
The change of the brightness, the color and the working mode of the indicator lamp 400 intuitively reflects the overvoltage, the undervoltage and the voltage oscillation phenomena of a voltage input pin in a main board interface, and the brightness adjustment and the flicker interval time of the indicator lamp 400 are configured according to preset fixed values, so that the defects that the brightness is not obviously reduced when the undervoltage value is small, the indicator lamp 400 is damaged due to the overlarge brightness increase when the overvoltage value is large, and the operator cannot timely sense the faults caused by the overlong flicker interval time when the voltage oscillation frequency is low are avoided.
Optionally, in the embodiment of the present application, the fault detection device further includes a display module 500, and the control module 100 is connected to the display module 500 and is further configured to display, via the display module 500, a number of a voltage input pin having a cold joint fault and a fault type, where the fault type includes at least one of an open circuit, a short circuit, an overvoltage, an undervoltage, and a voltage oscillation. The control module 100 can determine the type, pin structure and serial numbers of the pins of the current motherboard interface according to the currently used interface communication module 300, and if the voltage input signal of a certain voltage input pin is detected to have the phenomena of open circuit, short circuit, overvoltage, undervoltage or voltage oscillation, the serial numbers of the current voltage input pin and the fault type identification are displayed through the display module 500, wherein the open circuit, the short circuit, the overvoltage, the undervoltage or the voltage oscillation respectively correspond to different fault identifications. Compared with the existing fault code displayed by the main board diagnostic card only can represent the interface where the fault is located, the fault detection device can display the number of a specific fault pin through the display module 500, can display the specific fault type generated by the pin, greatly improves the convenience of fault detection in the main board interface, and ensures that operators can timely learn the accurate fault pin and fault type.
When the control module 100 performs performance test on the motherboard interface, a performance test request is firstly sent to the motherboard, after the motherboard obtains the performance test request, the motherboard performs data reading and writing operation on the storage module 200 in the fault detection device through the current interface and the interface communication module 300 connected with the current interface, the control module 100 obtains a data operation result of the data reading and writing operation through the storage module 200, meanwhile, the control module 100 directly obtains data execution parameters when the motherboard performs the data reading and writing operation through the interface communication module 300, and finally, the performance parameters of the performance test can be determined according to the data execution parameters and the data operation result.
Similarly, when the control module 100 performs a pressure test on the motherboard interface, the test flow is the same as the test flow of the performance test, that is, a pressure test request is sent to the motherboard first, after the motherboard obtains the pressure test request, the motherboard performs a data reading and writing operation on the memory module 200 in the fault detection device through the current interface and the interface communication module 300 connected with the current interface, the control module 100 obtains a data operation result of the data reading and writing operation through the memory module 200, meanwhile, the control module 100 directly obtains data execution parameters when the motherboard performs the data reading and writing operation through the interface communication module 300, and finally, the performance parameter of the pressure test can be determined according to the data execution parameters and the data operation result. The performance test is different from the pressure test in that the pressure test is a read-write data test on the current main board interface in a high load state, which reflects the communication performance of the communication link of the current main board interface in the high load state, and the performance test is a read-write data test on the current main board interface in a normal load (i.e. general load or low load) state, which reflects the communication performance of the communication link of the current main board interface in the normal load state.
The performance parameters comprise at least one of error rate, packet loss rate, speed, bandwidth and throughput, wherein the error rate (symbol error rate) and the packet loss rate are reliability indexes in the data transmission process and reflect the transmission precision of the current main board interface in the data transmission process, the speed, the bandwidth and the throughput reflect the transmission efficiency of the current main board interface in the data transmission process, the larger the error rate or the larger the packet loss rate is, the lower the data transmission precision is, the larger the speed, the larger the bandwidth or the larger the throughput is, and the higher the data transmission efficiency is. If the performance parameters of the interface do not meet the performance parameter threshold of the interface, it is obvious that transmission faults exist in the current mainboard interface.
Optionally, in this embodiment of the present invention, the control module 100 is specifically further configured to perform performance testing and/or pressure testing on the motherboard interface through the storage module 200 and the interface communication module 300, so as to obtain a transmission failure pin in each data transmission pin according to a performance parameter of each data transmission pin in the motherboard interface and a single-pin performance parameter threshold, where the single-pin performance parameter threshold is related to an interface performance parameter threshold of a current motherboard interface or is related to both an interface performance parameter threshold of the current motherboard interface and the number of data transmission pins.
The method comprises the steps of setting a single-pin bit error rate threshold and a single-pin packet loss rate threshold as an interface bit error rate threshold and an interface packet loss rate threshold of a current main board interface respectively, taking the quotient of the interface rate threshold and the number of data transmission pins of the current interface as the single-pin rate threshold, taking the quotient of the interface bandwidth threshold and the number of data transmission pins as the single-pin bandwidth threshold, taking the quotient of the interface throughput threshold and the number of data transmission pins as the single-pin throughput threshold, and if the performance parameters of any data transmission pin do not accord with the single-pin performance parameter threshold after performance test and/or pressure test, the data transmission pin has a transmission fault, namely the transmission fault pin.
Optionally, in the embodiment of the present invention, the control module 100 is specifically configured to perform a performance test on the motherboard interface through the storage module 200 and the interface communication module 300, so as to detect whether a first transmission failure pin exists in data transmission pins of the motherboard interface, and perform a pressure test on the motherboard interface, so as to detect whether a second transmission failure pin exists in data transmission pins of the motherboard interface, and determine that a cold joint failure exists in the target data transmission pins if the same target data transmission pins exist in the first transmission failure pin and the second transmission failure pin. Because the performance test and the pressure test are carried out at different time points and under different load states, if the same data transmission pin has transmission faults in the two test processes, the pin faults can be determined not to be determined by accidental external factors but by the virtual welding problem of the data transmission pin, so that the accuracy of detection results is ensured and the detection range of the virtual welding faults of the pin is enlarged while the virtual welding faults of the data transmission pin in a main board interface are detected.
Optionally, in the embodiment of the present invention, the control module 100 is specifically further configured to determine that the transmission failure of the data transmission pin is related to the cold joint failure of the data transmission pin if no cold joint failure is detected in the voltage input pins of the current motherboard interface and a transmission failure is detected in the data transmission pin of the current motherboard interface. When the voltage input pins in the interface have a cold joint fault, and the input voltage is smaller or the input voltage is unstable (namely, voltage oscillation exists), the voltage state can affect the data transmission efficiency and the data transmission accuracy of the interface, so that if no cold joint fault is detected in the voltage input pins of the current main board interface, but the transmission fault is detected in the data transmission pins, the transmission fault in the data transmission pins is caused by the cold joint fault of the data transmission pins, and therefore, the cold joint fault detection of the voltage input pins in the main board interface and the transmission fault detection of the data transmission pins realize the cold joint fault detection of the data transmission pins, and further ensure the accuracy of detection results.
According to the technical scheme, the fault detection device performs pin cold joint testing on the voltage input pins of the corresponding main board interface in the equipment to be tested through the interface communication module, so that cold joint fault detection on the voltage input pins is realized, the input voltage stability of the interface is ensured, the safety performance of the interface is improved, meanwhile, the performance test and/or the pressure test on the main board interface are performed through the storage module and the interface communication module, the transmission fault detection on the data transmission pins is realized, and the data transmission efficiency and the data transmission precision of the interface are improved.

Fig. 2 is a flowchart of a fault detection method provided in the second embodiment of the present invention, where the fault detection device is applicable to detecting a cold joint fault of a voltage input pin in a motherboard interface, and the method may be executed by a control module of the fault detection device in the first embodiment. As shown in fig. 2, the method includes:
S201, if a voltage input signal of a main board interface is obtained through an interface communication module, a first test signal is sent to the main board interface through the interface communication module.
S202, if the feedback signal of the main board interface for the first test signal is obtained through the interface communication module within the preset waiting time, judging whether the voltage input signal is not detected in each voltage input pin of the main board interface.
And S203, if the voltage input signal is not detected in the first voltage input pin, determining that the first voltage input pin has an open circuit and cold joint fault.
If the voltage input signal is detected in all the voltage input pins, the broken dummy solder pins are not existed in the current interface.
S204, if the feedback signal of the main board interface for the first test signal is not obtained through the interface communication module within the preset waiting time, judging whether the voltage input signal is detected in each voltage input pin of the main board interface.
And S205, if the voltage input signal is detected in the second voltage input pin, determining that the second voltage input pin has a short circuit and cold joint fault.
If no voltage input signal is detected in all the voltage input pins, the fact that the short circuit cold joint pin does not exist in the current interface is indicated.
