In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1A is a schematic structural diagram of a fault detection apparatus according to an embodiment of the present invention, where the apparatus includes: a control module 100, a storage module 200, and at least one interface communication module 300; the interface communication module 300 is connected to a corresponding motherboard interface of the device to be tested.
Since the motherboard of the electronic device usually includes a plurality of different types of interfaces, for example, a PCI (Peripheral Component interconnect) interface (i.e., PCI slot), a memory slot, a PCIe (PCI-Express) interface, an Industry Standard Architecture (ISA) slot, etc., the fault detection apparatus may also include a plurality of interface communication modules 300, and a structure of each interface communication module 300 matches a structure of a corresponding interface on the motherboard, so that when the fault detection apparatus performs fault detection, the fault detection apparatus may be respectively connected to the corresponding interface on the motherboard through each interface communication module 300; optionally, in the embodiment of the present invention, the type, structure, and number of the motherboard interface and the interface communication module 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 configured to perform a pin cold joint test on at least one motherboard interface through the at least one interface communication module 300, so as to detect whether a cold joint fault exists in a voltage input pin of the at least one motherboard interface; and performing a performance test and/or a stress 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 failure 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, the pin A2 in the PCI interface is used to input 12V voltage, the pin A5 is used to input 5V voltage, and the pin a27 is used to input 3.3V voltage; thus, the presence of a voltage input signal on each voltage input pin can be detected separately.
Specifically, after the fault detection device is connected to 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; after 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 the input voltage provided by the mainboard through any voltage input pin, the fault detection device sends a first test signal to the mainboard through the interface communication module 300; if a feedback signal of the mainboard for the first test signal is acquired, the mainboard is started, the input voltage acquired by the fault detection device is a normal voltage signal after the mainboard is started, and at the moment, if the voltage input signal is not detected on one or more voltage input pins, the voltage input pins are in an open circuit state due to the existence of a cold joint fault.
If a feedback signal of the mainboard for the first test signal is not acquired, the mainboard is not started at the moment, the input voltage acquired by the fault detection device is abnormal power supply caused by short circuit, and if a voltage input signal is detected on one or more voltage input pins at the moment, the voltage input pins are in a short circuit state due to the existence of a cold joint fault; therefore, the insufficient soldering detection of the voltage input pin is realized through open circuit detection and short circuit detection.
Optionally, in this embodiment of the present invention, the control module 100 is specifically configured to obtain a real-time input voltage of at least one voltage input pin in the motherboard interface through the interface communication module 300, 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; wherein the first cold joint fault pin is associated with an over-voltage, an under-voltage, or a voltage oscillation. The standard input voltage is the input voltage of the current voltage input pin in the normal working state, the pin A2 of the PCI interface in the above technical scheme is used for providing 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 current voltage input pin has an undervoltage phenomenon; if the real-time input voltage is larger than the corresponding standard input voltage within the preset detection time, indicating that the current voltage input pin has an overvoltage phenomenon; if the real-time input voltage at part of the moment is smaller than the standard input voltage and the real-time input voltage at part of the moment is larger than the standard input voltage within the preset detection time, indicating that the current voltage input pin has a voltage oscillation phenomenon, and the current voltage input pin is a cold joint fault pin (namely a first cold joint fault pin); through the detection to first rosin joint trouble pin in the mainboard interface, avoided voltage oscillation or the too high damage to external equipment of voltage, also prevented that voltage from crossing low effective operation that can't support external equipment, promoted the security performance of mainboard interface.
As shown in fig. 1B, optionally, in the embodiment of the present invention, the fault detection apparatus further includes at least one indicator lamp 400; the control module 100 is connected to the at least one indicator light 400, and is further configured to change the brightness and/or color of the corresponding indicator light 400 if the first cold solder joint fault pin is related to an over-voltage or an under-voltage; if the first cold-solder failure pin is related to voltage oscillation, the corresponding operation mode of the indicator light 400 is set to flash. The fault detection device can only comprise one indicator lamp 400, and when at least one first cold joint fault pin exists, namely, the brightness, the color or the working mode of the indicator lamp 400 are changed, a prompt is sent to a detector; wherein the working modes comprise normally on, normally off and flashing; the fault detection device may also include a plurality of indicator lights 400, and different indicator lights 400 are matched with the result of the serial number sorting of the voltage input pins one by one according to the serial number sequence, for example, the indicator light 400 No. 1 is matched with the voltage input pin with the most front serial number, and the voltage input pin may be an A2 pin, an A5 pin, or any other pin due to different pin distributions of different interfaces.
The brightness, color and working mode of the indicator light 400 change, not only intuitively reflect the over-voltage, under-voltage and voltage oscillation phenomena of a voltage input pin in a mainboard interface, but also the brightness adjustment and the flashing interval time of the indicator light 400 are configured according to preset fixed values, so that the problems that the brightness is not obviously reduced when the under-voltage value is small, the brightness is greatly improved to damage the indicator light 400 when the over-voltage value is large, and the flashing interval time is overlong when the voltage oscillation frequency is low are avoided, and an operator cannot timely sense the occurred fault.
Optionally, in the embodiment of the present invention, the fault detection apparatus further includes a display module 500; the control module 100 is connected to the display module 500, and is further configured to display, through the display module 500, a number and a fault type of a voltage input pin with a cold joint fault; wherein the fault type includes at least one of open circuit, short circuit, over voltage, under voltage, and voltage oscillation. The control module 100 can determine the type and pin structure of the current motherboard interface and the number of each pin according to the currently used interface communication module 300; 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, displaying the number and the fault type identification of the current voltage input pin through the display module 500; the open circuit, the short circuit, the overvoltage, the undervoltage or the voltage oscillation respectively correspond to different fault identifications. Compared with the fault code displayed by the conventional mainboard diagnosis card, the fault detection device can only represent the interface where the fault is located, not only can display the serial number of the specific fault pin through the display module 500, but also can display the specific fault type generated by the pin, greatly improves the detection convenience of the fault in the mainboard interface, and ensures that an operator can timely know the accurate fault pin and fault type.
When the control module 100 performs a performance test on the motherboard interface, it first sends a performance test request to the motherboard; after the mainboard acquires the performance test request, the mainboard performs read-write data 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 read-write data operation through the storage module 200; meanwhile, the control module 100 also directly obtains the data execution parameter when the motherboard executes the read-write data operation through the interface communication module 300; and finally, determining the performance parameters of the performance test 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; after the mainboard acquires the pressure test request, the mainboard performs read-write data 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 read-write data operation through the storage module 200; meanwhile, the control module 100 also directly obtains the data execution parameter when the motherboard executes the read-write data operation through the interface communication module 300; and finally, determining the performance parameters of the pressure test according to the data execution parameters and the data operation result. The performance test and the pressure test are different in that the pressure test is to perform read-write data test on a current mainboard interface in a high-load state, and reflects the communication performance of a communication link of the current mainboard interface in the high-load state; the performance test is to perform read-write data test on the current motherboard interface under a normal load (i.e., a normal load or a low load) state, and reflects the communication performance of the communication link of the current motherboard interface under the normal load state.
Wherein the performance parameter comprises at least one of bit error rate, packet loss rate, bandwidth and throughput; the bit 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 mainboard interface in the data transmission process; the speed, the bandwidth and the throughput reflect the transmission efficiency of the current mainboard 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 higher the rate, the greater the bandwidth or the greater the throughput, the higher the data transmission efficiency. If the performance parameter of the interface does not accord with the threshold value of the performance parameter of the interface, the transmission fault exists in the current mainboard interface obviously.
Optionally, in this embodiment of the present invention, the control module 100 is further specifically configured to perform a performance test and/or a pressure test 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; the single-pin performance parameter threshold is related to the interface performance parameter threshold of the current mainboard interface, or both the interface performance parameter threshold of the current mainboard interface and the number of data transmission pins.
Specifically, the single-pin error rate threshold and the single-pin packet loss rate threshold may be set as an interface error rate threshold and an interface packet loss rate threshold of the current motherboard interface, respectively; taking the quotient of the interface rate threshold and the number of data transmission pins of the current interface as a single-pin rate threshold, taking the quotient of the interface bandwidth threshold and the number of data transmission pins as a single-pin bandwidth threshold, and taking the quotient of the interface throughput threshold and the number of data transmission pins as a single-pin throughput threshold; after the performance test and/or the pressure test, if the performance parameters of any data transmission pin do not accord with the single-pin performance parameter threshold, a transmission fault exists in the data transmission pin, and the data transmission pin is a transmission fault pin; compared with the existing mainboard diagnosis card which can only determine the interface where the fault is located, the embodiment of the invention not only realizes the detection of the data transmission fault in the mainboard interface, but also determines that the transmission fault comes from a specific certain data transmission pin, thereby further improving the fault detection precision of the mainboard interface.
Optionally, in this embodiment of the present invention, the control module 100 is specifically configured to perform, through the storage module 200 and the interface communication module 300, a performance test on the motherboard interface to detect whether a first transmission fault pin exists in a data transmission pin of the motherboard interface, and perform a pressure test on the motherboard interface to detect whether a second transmission fault pin exists in the data transmission pin of the motherboard interface; and if the same target data transmission pin exists in the first transmission fault pin and the second transmission fault pin, determining that the target data transmission pin has a cold joint fault. 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 testing processes, the pin faults can be determined not to be determined by accidental external factors but to be caused by the insufficient soldering problem of the data transmission pin, and therefore, the accuracy of the detection result is ensured while the insufficient soldering fault detection of the data transmission pin in the mainboard interface is realized, and the detection range of the insufficient soldering fault of the pin is expanded.
Optionally, in this embodiment of the present invention, the control module 100 is further specifically configured to determine that the transmission fault of the data transmission pin is related to the cold solder joint fault of the data transmission pin if no cold solder joint fault is detected in any voltage input pin of the current motherboard interface and a transmission fault is detected in a data transmission pin of the current motherboard interface. When the voltage input pin in the interface has a cold solder fault, which causes a small input voltage or an unstable input voltage (i.e., there is voltage oscillation), the voltage state also affects the data transmission efficiency and the data transmission accuracy of the interface, and therefore, if no cold solder fault is detected in the voltage input pin of the current motherboard interface, but a transmission fault is detected in the data transmission pin, it indicates that the transmission fault in the data transmission pin is caused by the cold solder fault of the data transmission pin itself, and thus, the cold solder fault detection of the data transmission pin is realized by the cold solder fault detection of the voltage input pin in the motherboard interface and the transmission fault detection of the data transmission pin, and the accuracy of the detection result is further ensured.
According to the technical scheme of the embodiment of the invention, the fault detection device performs pin rosin joint test on the voltage input pin of the corresponding mainboard interface in the equipment to be tested through the interface communication module, so that the rosin joint fault detection of the voltage input pin is realized, the input voltage stability of the interface is ensured, and the safety performance of the interface is improved.

If the voltage input signals are detected in all the voltage input pins, the fact that the open-circuit cold-solder pins do not exist in the current interface is indicated.
And S204, if the feedback signal of the mainboard interface for the first test signal is not obtained through the interface communication module within the preset waiting time, judging whether a voltage input signal is detected in each voltage input pin of the mainboard interface.
