[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0033] Electronic devices (such as servers, mobile phones, tablets, laptops, desktop computers, etc.) are equipped with slot structures that allow memory cards to be inserted and enable signal transmission between the memory cards and the motherboard of the electronic devices.

[0034] In related technologies, slot structures are prone to signal disconnection failures due to manufacturing errors (such as poor contact between the slot and the memory card due to excessive slot size) and vibration of electronic devices (such as poor soldering between the slot structure and the link connected to it), thus making it impossible to transmit signals with the memory card.

[0035] The inventors of this application have discovered that a detection device can be designed, which can be equipped with a first connecting part, a triggering device, and an output device. The first connecting part can mimic the insertion structure of a memory card, allowing it to be inserted into a second connecting part (such as a slot structure) of an electronic device. This allows for the detection of the signal state of the second connecting part under both vibrating and non-vibrating electronic device scenarios. When an abnormal signal state is detected in the second connecting part, and the signal state of the second connecting part meets a target state, the triggering device causes the output device to output an alarm signal. At this time, the second connecting part and the link connected to it (such as the host part of a computer in the electronic device, and the second connecting part and...) can be monitored. The central processing unit on the motherboard of the main unit is electrically connected to the second connection part (including the connection part between the second connection part and the central processing unit). Repair is performed on this part. Then, if no alarm signal is received, the detection device can be disconnected from the second connection part, and the memory card can be inserted into the second connection part. In this way, the detection device can simulate the situation of the memory card being inserted into the second connection part and detect the signal status of the second connection part. Therefore, if no alarm signal is received, it can be determined that the manufacturing error of the second connection part is within a controllable range and that vibration has not caused a disconnection. In this case, removing the detection device and inserting the memory card can reduce the probability of a disconnection failure when the memory card is inserted into the second connection part.

[0036] Here, testing under vibration conditions can reduce the likelihood of memory card and second connection failures occurring during electronic device vibration, and the failure disappearing after the vibration subsides.

[0037] First aspect

[0038] This disclosure provides a detection device 10, see [link to details]. Figures 1 to 3 As shown, the detection device 10 may include: a detection element 11, a triggering device 12, and an output device 13. The detection element 11 is connected to a first connecting part 111, which is used to be inserted into a second connecting part 22 of the electronic device 21. The triggering device 12 is disposed on the detection element 11 and electrically connected to the first connecting part 111. The output device 13 is disposed on the detection element 11 and electrically connected to the triggering device 12. When the first connecting part 111 is inserted into the second connecting part 22, the triggering device 12 detects the signal state of the second connecting part 22, and when the signal state meets the target state, the output device 13 outputs an alarm signal.

[0039] Electronic device 21 can be a desktop computer host, a server, or other devices with a second connection part 22. The second connection part 22 can be a structure with a plug-in recess (such as the slot structure mentioned above). The plug-in recess can be used to plug in functional structures such as memory cards and expansion cards. The second connection part 22 can be connected to the motherboard and other devices on electronic device 21, so that functional structures such as memory cards and expansion cards can transmit data between the motherboard and the motherboard through the second connection part 22. For example, the second connection part 22 is a DIMM connector (Dual Inline Memory Module).

[0040] The detection component 11 is connected to a first connecting part 111, and the first connecting part 111 can move along... Figure 1 The Z-direction component 11 is inserted into the second connection portion 22 of the electronic device 21. The detection component 11 can be a circuit board with circuit layers and traces, enabling electrical connection and signal conduction with electronic components (such as trigger device 12, output device 13, etc.) of the detection device 10 via these traces. The first connection portion 111 can be configured to correspond to the portion of a memory card, expansion card, or other functional structure that inserts into the second connection portion 22, thus simulating the insertion of such functional structures. The detection component 11 and the first connection portion 111 can be connected together through integrated design, screw connection, or other fixed connection methods, or through clamping, snap-fit, or other detachable connection methods.

[0041] The trigger device 12 can be connected to the detection element 11 by means of bonding, welding, etc., and can be electrically connected to the first connection part 111 by wires exposed on the outer surface of the detection element 11, or by embedding wires through through holes in the detection element 11, or by welding to the first connection part 111, or by other connection methods. The trigger device 12 can detect the signal state of the second connection part 22 in real time and control the output of the output device 13 according to the signal state. The signal state includes: low level state (second connection part 22 is in a stable signal state), high level state (second connection part 22 is in a disconnected signal state), and high-low level switching state (second connection part 22 is in a switching state between stable signal and disconnected signal). The trigger device 12 can output a high level to the output device 13 when it detects a high level state or a high-low level switching state.

[0042] The output device 13 can be fixed or detachably connected to the detection element 11 by means of bonding, welding, etc. It can be electrically connected to the trigger device 12 via wires exposed on the outer surface of the detection element 11, wires embedded in through holes within the detection element 11, welding to the trigger device 12, or other connection methods. The output device 13 is used to output an alarm signal, which can be perceived visually, audibly, or through other means. The output device 13 outputs an alarm signal when the trigger device 12 outputs a high-level signal to alert personnel.

[0043] In one example, this disclosure provides a detection device 10, see [link to relevant documentation]. Figures 1 to 3 As shown, the detection device 10 may include: a detection element 11, a trigger device 12, and an output device 13. The detection element 11 is connected to a first connection part 111, which is used to insert into a second connection part 22 of an electronic device 21, where the electronic device 21 is a server. The second connection part 22 is a recess for inserting memory cards, expansion cards, and other functional structures. The trigger device 12 is disposed on the detection element 11 and is a D flip-flop electrically connected to the first connection part 111. The output device 13 is disposed on the detection element 11 and is a light-emitting diode electrically connected to the trigger device 12. When the first connection part 111 is inserted into the second connection part 22, the motherboard connected to the second connection part 22 in the server supplies power to the detection device 10, so that the trigger device 12 can detect the signal status on the link from the second connection part 22 to the central processing unit 23 on the motherboard, and output a high level to the output device 13 when the signal status meets the target status, so that the output device 13 emits light to output an alarm signal.

[0044] One detection method of the detection device 10 includes:

[0045] S101: Insert the first connecting part 111 into the second connecting part 22 to form a physical and electrical connection between the detection device 10 and the host;

[0046] S102: In the scenarios of vibrating electronic device 21 and non-vibrating electronic device 21 respectively, the triggering device 12 collects the signal status (such as high level state, low level state, high-low level switching state) of the second connection part 22 through the first connection part 111, and outputs a high level to the output device 13 when the detected electrical signal is in a high level state or a high-low level switching state.

[0047] S103: When output device 13 receives a high level from trigger device 12, it outputs an alarm signal;

[0048] S104: The staff senses the alarm signal and repairs or replaces the second connection part 22 and its link.

[0049] S105: Cycle through S101-S104. If the alarm signal of S103 does not appear, the second connection part 22 and the link connected to it can be considered to be normal. At this time, the first connection part 111 and the second connection part 22 can be separated, and the memory card, expansion card and other functional structures adapted to the second connection part 22 can be inserted into the second connection part 22.

[0050] In this embodiment, the detection device 10 may include: a detection element 11, a trigger device 12, and an output device 13. The first connection portion 111 connected to the detection element 11 can mimic the plug-in portion of a memory card, expansion card, or similar functional structure, so as to be able to plug into the second connection portion 22 in the electronic device 21. The trigger device 12 is electrically connected to the first connection portion 111 so as to determine through the first connection portion 111 whether the signal state of the second connection portion 22 is in a normal low-level state, a high-level state under fault conditions, or a high-low level switching state, and outputs a high level to the output device 13 under fault conditions, so that the output device 13 outputs an alarm signal. When the connector 22 is plugged in, the detection device 10 will automatically detect that it has been plugged into the second connector 22 and power it on. Then, it will start to monitor the signal link between the second connector 22 and the central processing unit 23 on the motherboard in real time. When there is poor contact between the first connector 111 (such as a first connector pin 1111) and the second connector 22 (such as a second connector pin 221 corresponding to a first connector pin 1111) or when there is a cold solder joint on the signal link on the motherboard where the central processing unit 23 is located, the trigger device 12 of the detection device 10 will feed back the signal change to the output device 13. The output device 13 will output accordingly, and the problematic signal can be identified. In this way, the detection device 10 can simulate the situation where the memory card is inserted into the second connection part 22 and detect the signal status of the second connection part 22. Then, it can determine that the manufacturing error of the second connection part 22 is within a controllable range and the vibration has not caused a disconnection when no alarm signal is received. In this case, removing the detection device 10 and inserting the memory card, expansion card and other functional structures can reduce the probability of the memory card, expansion card and other functional structures disconnecting when inserted into the second connection part 22.

[0051] In some embodiments, the outer contour shape, size, material and other properties of the detection component 11 can meet the same conditions as the functional structure of the memory card, expansion card and other functional structures, so as to be closer to the setting of the memory card, expansion card and other functional structures, thereby making the simulation results more accurate.

[0052] In some embodiments, see Figure 1 and Figure 2 As shown, the first connecting part 111 includes a plurality of first connecting pins 1111; the second connecting part 22 includes a plurality of second connecting pins 221, and when the second connecting part 22 is inserted into the first connecting part 111, the plurality of second connecting pins 221 are electrically connected to the plurality of first connecting pins 1111 respectively; wherein, the target state includes at least one of the following:

[0053] At least one second connection pin 221 is in a high-level state;

[0054] At least one of the second connection pins 221 is in a high-low level switching state.

[0055] In other words, the second connection part 22 (such as a DIMM connector) on the electronic device 21 has a insertion recess, and a plurality of second connection pins 221 are provided in the insertion recess. The plurality of second connection pins 221 can be arranged in one row or multiple rows. The first connection part 111 can also be provided with a plurality of first connection pins 1111. The plurality of first connection pins 1111 and the plurality of second connection pins 221 are adapted to each other so that when the first connection part 111 is inserted into the second connection part 22, the plurality of first connection pins 1111 and the plurality of second connection pins 221 can make physical contact with each other and achieve a one-to-one electrical connection. When some or all of the plurality of second connection pins 221 are in a high-level state, or some or all of the plurality of second connection pins 221 are in a high-low level switching state, or some of the plurality of second connection pins 221 are in a high-level state and some are in a high-low level switching state, the trigger device 12 can send a high level to the output device 13 so that the output device 13 can output an alarm signal.

[0056] In this embodiment, by setting multiple first connection pins 1111 and second connection pins 221 to be connected in a one-to-one correspondence, the trigger device 12 can simultaneously detect the independent signal status of multiple pins, thereby improving detection efficiency.

[0057] In some embodiments, see Figure 1 As shown, the trigger device 12 includes: a plurality of trigger units 121, which are arranged in parallel, and one trigger unit 121 is electrically connected to at least two second connection pins 221.

[0058] Here, when the trigger device 12 includes multiple trigger units 121 arranged in parallel, and one trigger unit 121 is electrically connected to at least two second connection pins 221, the number of output devices 13 can be one or more. For example, the number of output devices 13 is one (such as a display device) and has multiple display areas. Multiple trigger units 121 can correspond to multiple display areas respectively, so that when the trigger unit 121 emits a high level, the corresponding display area displays text content, pictures, etc. representing alarm information; or, for example, the number of output devices 13 is one (such as a light-emitting element), and multiple trigger units 121 are connected to the light-emitting element. When different trigger units 121 emit a high level, the light-emitting element emits light with different colors, frequencies, and other attributes; or, for example, the number of output devices 13 is multiple (such as... Figure 1 As shown in the figure, multiple light-emitting elements are connected to multiple triggering units 121, which are respectively associated with multiple light-emitting elements. When the triggering unit 121 emits a high level, the corresponding light-emitting element emits light to display an alarm message.

[0059] In this embodiment, multiple triggering units 121 can detect multiple connected second connection pins 221 in a near-synchronous manner, thereby improving detection efficiency.

[0060] Different electronic devices 21 have different outlines, lengths, widths, depths, and numbers of connecting pins in their second connecting portions 22. Therefore, in some embodiments, the first connecting portion 111 is detachably connected to the detection element 11, so that first connecting portions 111 with different shapes and / or different first connecting pin configurations can be connected to the detection element 11. In this way, when detecting the second connecting portion 22 of one electronic device 21, the first connecting portion 111 adapted to that second connecting portion 22 can be connected to the detection element 11, and when detecting the second connecting portion 22 of another electronic device 21, the first connecting portion 111 adapted to that second connecting portion 22 of the other electronic device 21 can be connected to the detection element 11; thus, it is possible to detect second connecting portions 22 with different configurations.

[0061] In some embodiments, a plurality of first connecting portions 111 are arranged side by side on the detection member 11, and at least one first connecting portion 111 is adapted to be connected to a second connecting portion 22.

[0062] The configuration of multiple first connection parts 111 can be consistent, so that in the event of a failure of one first connection part 111, connection detection can be performed through other first connection parts 111, thereby reducing detection interruptions. Alternatively, they can be simultaneously plugged into multiple identical second connection parts 22 of the same electronic device 21 to synchronously detect the signal status of multiple identical second connection parts 22 of the same electronic device 21. The configuration of multiple first connection parts 111 can also be inconsistent, so that different first connection parts 111 on the same detection device 10 can be used to detect the second connection parts 22 of different electronic devices 21, or they can be simultaneously plugged into multiple second connection parts 22 with different configurations on the same electronic device 21 to synchronously detect the signal status of multiple different second connection parts 22 of the same electronic device 21. In this way, the versatility of the detection device 10 can be improved.

[0063] In some embodiments, see Figure 2 As shown, the detection device 10 further includes an electronic buffer 14, which is disposed on the detection element 11. The input terminal of the electronic buffer 14 is electrically connected to the first connection portion 111, and the output terminal of the electronic buffer 14 is electrically connected to the trigger device 12. The electronic buffer 14 is used to adjust the signal strength between the first connection portion 111 and the trigger device 12. The electronic buffer 14 (BUFFER, basic logic unit) can transmit the signal state of the second connection portion 22 stably (reducing signal distortion and attenuation, eliminating signal jitter and noise) to the trigger device 12 to ensure signal integrity.

[0064] In some embodiments, see Figures 1 to 3 As shown, the detection device 10 may further include a power supply device 15, which is fixedly or detachably disposed on the detection element 11 and is arranged on the line between the first connection part 111 and the electronic buffer element 14.

[0065] See one example. Figure 1 As shown, the power supply device 15 may include a battery holder 151 and a button battery. The battery holder 151 is fixed on the detection element 11 and has a receiving space 152. The button battery is detachably disposed in the receiving space 152, and when disposed in the receiving space 152, the button battery can supply power to electrical devices such as the first connection part 111, the trigger device 12, the output device 13, and the second connection part 22. Here, the detection device 10 may also be provided with a switch 153 electrically connected to the power supply device 15. The switch 153 may be a manually operated switch, so that the power supply to the power supply device 15 can be disconnected manually when necessary.

[0066] In this embodiment, when the first connection part 111 is plugged into the second connection part 22 and the link connected to the second connection part 22 (such as the motherboard and the central processing unit 23 on it) is powered on, the detection device 10 can perform detection work with the power support of the link connected to the second connection part 22, and the current provided by the central processing unit 23 will not be delivered to the power supply device 15, so as to reduce the waste of power resources of the central processing unit 23 and protect the power supply device 15; when the first connection part 111 is plugged into the second connection part 22 and the link connected to the second connection part 22 (such as the motherboard and the central processing unit 23 on it) is not powered on, the power supply device 15 can supply power to the first connection part 111, the trigger device 12, the output device 13, and the second connection part 22, so as to support the detection when the link of the second connection part 22 is not powered on.

[0067] In some embodiments, see Figure 3 As shown, the detection device 10 further includes: a first unidirectional conductive device 161, the input terminal of the first unidirectional conductive device 161 being electrically connected to the output terminal of the power supply device 15, and the output terminal of the first unidirectional conductive device 161 being connected to the line between the first connection part 111 and the electronic buffer device 14.

[0068] The first unidirectional conductive device 161 has the characteristics of unidirectional conduction and reverse cutoff. Here, it allows current to enter from its input terminal and exit from its output terminal in the forward direction, but does not allow the current to reverse. In this way, the current provided by the central processing unit 23 will not be delivered to the power supply device 15, so as to reduce the waste of power resources of the central processing unit 23 and protect the power supply device 15.

[0069] In some embodiments, the output device 13 includes at least one of the following:

[0070] An audio player is used to play audio information corresponding to the alarm signal.

[0071] Content display to show text and / or image information corresponding to the warning signal;

[0072] A light emitter that emits color information corresponding to the warning signal.

[0073] In other words, the output device 13 may include an audio player, a content display, a light emitter, an audio player and a content display, an audio player and a light emitter, or a content display and a light emitter. Thus, there are many different configuration options.

[0074] Second aspect

[0075] This disclosure provides a detection system 20, see [link to relevant documentation] Figure 2 and Figure 3As shown, the detection system 20 may include: an electronic device 21 and a detection device 10. The electronic device 21 has a motherboard and a second connection part 22 electrically connected to the motherboard. The detection device 10 may include: a detection element 11, a trigger device 12, and an output device 13. The detection element 11 is connected to a first connection part 111, which is used to be inserted into the second connection part 22. The trigger device 12 is disposed on the detection element 11 and electrically connected to the first connection part 111. The output device 13 is disposed on the detection element 11 and electrically connected to the trigger device 12. When the first connection part 111 is inserted into the second connection part 22, the trigger device 12 detects the signal state of the second connection part 22, and when the signal state meets the target state, the output device 13 outputs an alarm signal.

[0076] Electronic device 21 can be a computer host, a server, or other devices equipped with a second connection part 22. The second connection part 22 can be a structure with a insertion recess (such as the slot structure mentioned above). The insertion recess can be used to insert functional structures such as memory cards and expansion cards. The second connection part 22 can be connected to components such as the motherboard on electronic device 21, so that functional structures such as memory cards and expansion cards can transmit data between the central processing unit 23 on the motherboard through the second connection part 22.

[0077] Here, when the electronic device 21 is powered on, power can be supplied to the detection device 10 through the second connection 22 to enable the detection device 10 to perform detection work; when the electronic device 21 is not powered on, the power supply device 15 of the detection device 10 can supply power to the detection device 10, the second connection 22, and their link to enable the detection device 10 to perform detection work. For example: see Figure 3 As shown, the voltage supplied by the electronic device 21 through the second connection 22 is 3.3V, and the voltage of the power supply device 15 is 3V. Both are electrically connected to the electronic buffer device 14, the trigger device 12, and the output device 13 of the detection device 10 through the second unidirectional conductive device 162 and the first unidirectional conductive device 161, respectively. When the electronic device 21 is powered on, the voltage supplied by the electronic device 21 through the second connection 22 is higher than the voltage supplied by the power supply device 15, so that it provides power to the detection device 10, and the presence of the second unidirectional conductive device 162 prevents it from simultaneously providing power to the power supply device 15. Conversely, when the electronic device 21 is not powered on, the power supply device 15 provides power to the detection device 10, and the presence of the first unidirectional conductive device 161 prevents it from simultaneously providing power to the central processing unit 23. The detection principle of the logic circuit of the detection device 10 can be found in [reference needed]. Figure 2When a short-circuit event greater than microseconds (µs) occurs on the link between the first connection 111 of the detection device 10 and the central processing unit 23, the signal change will cause the trigger device 12 to output a high level, thereby illuminating the LED of the output device 13. Alternatively, a monitoring device can be set to monitor the voltage / current status of the second connection 22 and its link. If the detected voltage / current status indicates that the electronic device 21 is powered on, the power supply device 15 can be controlled to not provide power, thus allowing the electronic device 21 to provide power.
