Disclosure of Invention
Embodiments of the present invention provide a method, a terminal, and a detection apparatus for detecting a BTB buckling reliability, which can detect whether a BTB device is not buckled (or buckled insecurely), and further can determine whether a failure is caused by the BTB device in the apparatus when the apparatus fails, thereby improving efficiency of failure location.
In order to achieve the above purpose, the embodiment of the invention adopts the following technical scheme:
first, the structure of BTB according to the present embodiment will be described: the BTB is used for connecting a first device and a second device, the BTB is composed of a first plug-in component and a second plug-in component which are mutually buckled, the first plug-in component is connected with the first device, and the second plug-in component is connected with the second device. Through pegging graft first grafting subassembly and second grafting subassembly together to with the BTB lock, just also realized being connected of first device and second device.
In a first aspect, a method for detecting board-to-board connector BTB buckling reliability is disclosed: the method comprises the following steps:
the detection device firstly acquires the output voltage of the detection circuit and secondly judges whether the output voltage of the detection circuit is the same as the input voltage of the detection circuit.
If the output voltage of the detection circuit is the same as the input voltage of the detection circuit, determining that the BTB is reliably buckled; and if the output voltage of the detection circuit is different from the input voltage of the detection circuit, determining that the BTB buckling is unreliable.
It should be noted here that, the buckling reliability of the BTB can be determined by comparing the input voltage and the output voltage of the detection circuit, because the detection circuit is formed by sequentially connecting N groups of detection pins of the BTB in series, and each group of detection pins of the N groups of detection pins of the BTB is respectively formed by a first detection pin disposed on the first plug assembly and a second detection pin disposed on the second plug assembly, when the first plug assembly and the second plug assembly are buckled, the first detection pin and the second detection pin are connected. In addition, N is a positive integer.
The first plug-in component and the second plug-in component of the BTB are reliably connected, the BTB is equivalent to a conductor, and ideally, no voltage drop is generated between a group of detection pins of the first plug-in component and the second plug-in component. If each group of detection pins of the BTB is reliably connected, no voltage drop is generated between any two detection pins connected in series in the detection circuit, and the output voltage of the detection circuit is the same as the input voltage at the moment. The reverse reasoning can be obtained, if the output voltage of the detection circuit is the same as the input voltage of the detection circuit, it is determined that no voltage drop is generated between any two detection pins connected in series in the detection circuit, and therefore it can be determined that the BTB connection is reliable.
When the first plug assembly and the second plug assembly are buckled firmly, the contact impedance between the first plug assembly and the second plug assembly is changed, the impedance between a group of detection pins on the first plug assembly and the second plug assembly is also changed, a voltage drop is formed between the two detection pins, and the output voltage of the detection circuit is reduced compared with the input voltage. When the first plug assembly and the second plug assembly are not buckled, a group of detection pins on the first plug assembly and the second plug assembly are not conducted, and the two detection pins on the first plug assembly and the second plug assembly are broken, so that the detection circuit cannot form a passage, and the output voltage of the detection circuit is zero. If the output voltage of the detection circuit is different from the input voltage of the detection circuit (possibly, the output voltage is smaller than the input voltage or the output voltage is zero), it is determined that there is an open circuit or a partial voltage between the detection pins connected in series in the detection circuit, and therefore it can be determined that the BTB buckling is unreliable.
In the prior art, when a terminal has a fault, whether the fault is caused by a BTB device arranged in the terminal or not can not be determined at present, and the fault positioning efficiency is influenced. The method provided by the invention can detect whether the BTB device arranged on the terminal is not buckled (or buckled insecurely), and further can confirm whether the fault is caused by the BTB device when the terminal has the fault, thereby improving the efficiency of fault positioning.
With reference to the first aspect, in a first possible implementation manner of the first aspect, if the input end of the detection circuit is connected in series to a power supply network, and if the output voltage of the detection circuit is smaller than the input voltage of the detection circuit or the output voltage of the detection circuit is zero, it is determined that the BTB buckling is unreliable.
If the input power supply of the detection circuit is a power supply network, the output voltage of the detection circuit is different from the input voltage of the detection circuit, which includes two situations: the output voltage is less than the input voltage of the detection circuit or the output voltage is zero. When the output voltage meets one of the two conditions, the BTB buckling is determined to be unreliable. If the output voltage is detected to be 0V, at least one group of disconnected detection pins exists in the N groups of detection pins of the BTB, namely the first plug-in component and the second plug-in component of the BTB are not buckled completely. If the output voltage is detected to be smaller than the input voltage of the detection circuit, the BTB is judged to be not fastened firmly, namely the first plug-in component and the second plug-in component of the BTB are loosened and not fastened completely.

When the BTB is reliably buckled, the detection circuit is a path, and the voltage GND network, the preset resistor and the reference power network form a loop, so that the voltage detector detects that the voltage is zero. When the BTB is not reliable in buckling, the detection circuit is open-circuit, the output end of the detection circuit forms a path with the preset point and the reference power network, the preset resistor generates partial voltage, and the voltage detector detects that the voltage is the voltage of the preset resistor, namely the voltage value of the reference power network.
With reference to the first possible implementation manner of the first aspect, in a third possible implementation manner of the first aspect, if the output voltage of the detection circuit is zero, it is determined that at least one group of disconnected detection pins exists in the N groups of detection pins of the BTB.
If the input power supply of the detection circuit is a power supply network and the output voltage of the detection circuit is zero, the detection circuit is an open circuit, and then the disconnected detection pins in the N groups of detection pins can be further determined. It may be that the first detection pin and the second detection pin are not plugged together.

Certainly, the protruded pins on the first plug-in component and the hole pins on the second plug-in component are in one-to-one correspondence, and the corresponding protruded pins and the hole pins need to be plugged together when being buckled. For example, the BTB has 40 pairs of pins, and when the BTB is fastened, it is required to ensure that the pin No. 10 on the first plug assembly is plugged with the pin No. 10 on the second plug assembly.

The memory 104 may also comprise a combination of the above types of memory.
Example 2:
an embodiment of the present invention provides a method for detecting a buckling reliability of a BTB, as shown in fig. 3, the method includes the following steps:
201. the output voltage of the detection circuit is acquired.
In a specific implementation, the output voltage of the detection circuit is obtained by the detection module 202 connected to the detection circuit.
It should be noted that the BTB is used to connect the first device and the second device. As shown in fig. 4, the BTB is composed of a first plug assembly and a second plug assembly that are fastened to each other. In addition, the BTB further comprises a group of detection pins which are respectively a first detection pin arranged on the first plug-in component and a second detection pin arranged on the second plug-in component. As shown in fig. 4, when the first plug assembly is engaged with the second plug assembly, the first detection pin is connected to the second detection pin. In addition, the first plug-in assembly is connected with a first device, and the second plug-in assembly is connected with a second device.
The detection circuit by BTB's N group detects the pin and establishes ties in proper order and constitutes, wherein, each group in BTB's N group detects the pin and equallys divide do not by set up in first detection pin of first grafting subassembly with set up in the second of second grafting subassembly detects the pin and constitutes, works as when first grafting subassembly and second grafting subassembly lock joint, first detection pin with the second detects the pin and connects. And N is a positive integer.
For example, as shown in fig. 5, the display screen is connected to the mobile phone board through a BTB, and the BTB includes four groups of detection pins (that is, 4 groups of detection pins are provided between the display screen and the mobile phone board), and are respectively disposed in the first plug-in component and the second plug-in component. When the first plug assembly and the second plug assembly of the BTB are buckled, the BTB comprises a group of detection pin connections. Referring to fig. 5, 4 sets of detection pins are connected in series in sequence to form a detection circuit.
Generally, the first plug assembly and the second plug assembly constituting the BTB are respectively called a male plug and a female plug, the number of pins of the male plug and the number of pins of the female plug are the same, and the male plug and the female plug are ensured to be buckled, so that the pins with the same number on the male plug and the female plug are buckled correspondingly. In the embodiment of the invention, a group of detection pins included in the BTB are pins arranged on the male head and the female head respectively, and the pin numbers of the two detection pins are the same. For example, the 12 th pin of the male connector is set as the detection pin, and the 12 th pin of the corresponding female connector is also required to be set as the detection pin. Thus, when the BTB snaps, a set of sense pins are connected.
In specific implementation, the output end of the detection circuit is connected with a voltage detector, and the output voltage of the detection circuit is measured and obtained through the voltage detector.
202. And judging whether the output voltage of the detection circuit is the same as the input voltage of the detection circuit.
In a specific implementation, the processor 203 determines whether the output voltage of the detection circuit obtained by the detection module 202 is the same as the input voltage of the detection circuit. Specifically, the input end of the detection circuit is connected in series with an input power supply (power supply module 201), and the input power supply provided by the power supply module 201 may be a power supply network or a GND network. If the input power supply is a power supply network, the input voltage of the detection circuit is a non-zero voltage value, and if the input power supply is a GND network, the input voltage of the detection circuit is zero.
If the input end of the detection circuit is a power supply network, the output end of the detection circuit is only connected with the voltage detector, and the circuit diagram is shown in fig. 6. Namely, N groups of BTB detection pins are sequentially connected in series, the input end of each BTB detection pin is connected with a power supply network in series, and the output end of each BTB detection pin is connected with a voltage detector.
If the input end of the detection circuit is a GND network, the output end of the detection circuit is not only connected with the voltage detector, but also connected in parallel with a reference power network, and a preset resistor is connected in series between the reference power network and the output end, and a circuit diagram is shown in fig. 7.
203. And if the output voltage of the detection circuit is the same as the input voltage of the detection circuit, determining that the BTB is reliably buckled.
In a specific implementation, both steps 203 and 204 are executed by the processor 203.
If the first plug-in component and the second plug-in component of the BTB are reliably connected, the BTB is equivalent to a conductor, and ideally, no voltage drop is generated between a group of detection pins of the first plug-in component and the second plug-in component. If each group of detection pins of the BTB is reliably connected, no voltage drop is generated between any two detection pins connected in series in the detection circuit, and the output voltage of the detection circuit is the same as the input voltage at the moment. The reverse reasoning can be obtained, if the output voltage of the detection circuit is the same as the input voltage of the detection circuit, it is determined that no voltage drop is generated between any two detection pins connected in series in the detection circuit, and therefore it can be determined that the BTB connection is reliable.
For example, in conjunction with the circuit diagram shown in fig. 6, the detection circuit is connected in series with a power supply network having an input power supply of 5V, and an output terminal is connected to the voltage detector. And if the voltage detector detects that the voltage is also 5V, judging that the BTB is reliably buckled.
With reference to the circuit diagram shown in fig. 7, the input power source of the detection circuit connected in series is a GND network, and the output terminal is connected to the voltage detector and is subjected to pull-up processing and connected in parallel with the 3V reference power source network. When the BTB is reliably buckled, the detection circuit is a path, and the voltage GND network, the preset resistor and the reference power network form a loop, so that the voltage detector detects that the voltage is zero. For example, if the voltage detector detects that the voltage is 0V, it is determined that the BTB fastening is reliable.
204. And if the output voltage of the detection circuit is different from the input voltage of the detection circuit, judging that the BTB buckling is unreliable.
When the first plug assembly and the second plug assembly are buckled firmly, the contact impedance between the first plug assembly and the second plug assembly is changed, the impedance between a group of detection pins on the first plug assembly and the second plug assembly is also changed, a voltage drop is formed between the two detection pins, and the output voltage of the detection circuit is reduced compared with the input voltage. When the first plug assembly and the second plug assembly are not buckled, a group of detection pins on the first plug assembly and the second plug assembly are not conducted, and the two detection pins on the first plug assembly and the second plug assembly are broken, so that the detection circuit cannot form a passage, and the output voltage of the detection circuit is zero. The reverse deduction can be obtained, if the output voltage of the detection circuit is different from the input voltage of the detection circuit, the detection pins connected in series in the detection circuit are judged to have open circuit or partial voltage, and therefore the BTB buckling can be judged to be unreliable.
For example, in conjunction with the circuit diagram shown in fig. 6, the detection circuit is connected in series with a power supply network having an input power supply of 5V, and an output terminal is connected to the voltage detector. And if the voltage detector detects that the voltage is not 5V, judging that the BTB buckling is unreliable. Specifically, if the output voltage is detected to be 0V, it is determined that at least one group of disconnected detection pins exists in the N groups of detection pins of the BTB, that is, the first plug assembly and the second plug assembly of the BTB are not buckled at all. If the output voltage is detected to be less than 5V (not 0), the BTB is judged to be not fastened firmly, namely the first plug-in component and the second plug-in component of the BTB are loosened and not fastened completely.
With reference to the circuit diagram shown in fig. 7, the input power source connected in series to the detection circuit is a GND network, the output terminal is connected to the voltage detector and is pulled up, and the input power source is connected in parallel to the 3V reference power source network, and a preset resistor is connected in series between the reference power source network and the output terminal. When the BTB is not reliable in buckling, the detection circuit is open-circuit, the output end of the detection circuit and the reference power network form a passage, the preset resistor generates partial voltage, and the voltage detector detects that the voltage is the voltage of the preset resistor, namely the voltage value of the reference power network. For example, when the voltage detector detects that the voltage is 3V, which is the voltage value of the reference power network, it determines that the BTB buckling is unreliable.
In a preferred embodiment of the present invention, when an input power source connected in series to the detection circuit is a power network, and an output terminal of the detection circuit is connected to the voltage detector, if an output voltage of the detection circuit is zero, it is determined that at least one group of disconnected detection pins exists in the N groups of detection pins of the BTB.
The invention provides a method for detecting the buckling reliability of a BTB (Business to Board), which comprises the steps of obtaining the output voltage of a detection circuit; judging whether the output voltage of the detection circuit is the same as the input voltage of the detection circuit; if the output voltage of the detection circuit is the same as the input voltage of the detection circuit, judging that the BTB is reliably buckled; and if the output voltage of the detection circuit is different from the input voltage of the detection circuit, judging that the BTB buckling is unreliable. The detection circuit is formed by sequentially connecting N groups of detection pins of the BTB in series. In the prior art, when a terminal has a fault, whether the fault is caused by a BTB device arranged in the terminal or not can not be determined at present, and the fault positioning efficiency is influenced. The method provided by the invention is convenient for the detection device to detect whether the BTB device arranged on the terminal is not buckled (or is not buckled firmly), and further can confirm whether the fault is caused by the BTB device when the terminal has the fault, thereby improving the efficiency of fault positioning.
Example 3:
in an embodiment of the invention, a terminal 30 is provided, as shown in fig. 8, the terminal 30 includes a first device 301 and a second device 302. A BTB303 is disposed between the first device 301 and the second device 302. The BTB303 is composed of a first plug assembly 3031 and a second plug assembly 3032 which are fastened to each other, the first plug assembly 3031 is connected with the first device 301, and the second plug assembly 3032 is connected with the second device 302.
As shown in fig. 8, the terminal 30 further includes: a detection circuit 304. The detection circuit by BTB's N group detects the pin and establishes ties in proper order and constitutes, wherein, each group in BTB's N group detects the pin and equallys divide do not by set up in first detection pin of first grafting subassembly with set up in the second of second grafting subassembly detects the pin and constitutes, works as when first grafting subassembly and second grafting subassembly lock joint, first detection pin with the second detects the pin and connects.
It should be noted that the first device 301 may be a display device, such as: and the second device can be a mobile phone single board. The first plug assembly 3031 and the second plug assembly 3032 can be male heads and female heads of BTBs.
The detection circuit 304 does not affect other functions of the terminal, only connects the detection pins of the BTB in series, and does not affect other functions of the detection pins. When the BTB buckling reliability of the terminal is detected, the detection mode of the terminal is triggered, namely a group of detection pins of the BTB do not perform data transmission any more and are only used for detecting whether the BTB buckling is reliable or not.
When the terminal breaks down, the detection circuit can be used for judging whether the fault of the terminal is caused by unreliable BTB buckling or not during fault positioning, and the fault positioning efficiency is improved. The method specifically comprises the following steps: the input end of the detection circuit is connected with an input power supply in series, and the input power supply is used for inputting the input voltage of the detection circuit to the detection circuit; the output end of the detection circuit is connected with a voltage detector, and the voltage detector is used for detecting the output voltage of the detection circuit. And if the output voltage of the detection circuit is the same as the input voltage of the detection circuit, judging that the BTB is reliably buckled.
And if the output voltage of the detection circuit is different from the input voltage of the detection circuit, judging that the BTB buckling is unreliable.
It should be noted that the input power supply is a power ground GND network or a power supply network.

The detection circuit 404 does not affect other functions of the terminal, only connects the detection pins of the BTB in series, and does not affect other functions of the detection pins. When the BTB buckling reliability of the terminal is detected, the detection mode of the terminal is triggered, namely a group of detection pins of the BTB do not perform data transmission any more and are only used for detecting whether the BTB buckling is reliable or not.

In the prior art, when a device has a fault, whether the fault is caused by a BTB device or not cannot be determined at present, and the fault positioning efficiency is influenced. The terminal provided by the invention is convenient for the detection device to detect whether the BTB device arranged on the terminal is not buckled (or is not buckled firmly), so that whether the fault is caused by the BTB device can be determined when the terminal has the fault, and the fault positioning efficiency is improved.
Example 5:
an embodiment of the present invention provides a detection apparatus 50, configured to perform BTB fastening reliability detection on a terminal according to embodiment 2, where as shown in fig. 10, the detection apparatus 50 includes: an acquisition unit 501, a judgment unit 502, and a determination unit 503.
An obtaining unit 501, configured to obtain an output voltage of the detection circuit; the detection circuit by BTB's N group detects the pin and establishes ties in proper order and constitutes, wherein, each group in BTB's N group detects the pin and equallys divide do not by set up in first detection pin of first grafting subassembly with set up in the second of second grafting subassembly detects the pin and constitutes, works as when first grafting subassembly and second grafting subassembly lock joint, first detection pin with the second detects the pin and connects.
A determining unit 502, configured to determine whether the output voltage of the detection circuit acquired by the acquiring unit 501 is the same as the input voltage of the detection circuit.
A determining unit 503, configured to determine that the BTB is reliably buckled if the determining unit 502 determines that the output voltage of the detection circuit is the same as the input voltage of the detection circuit.
The first plug assembly and the second plug assembly of the BTB are reliably connected, and the BTB is equivalent to a conductor and is not subjected to voltage drop when being respectively arranged between the two detection pins of the first plug assembly and the second plug assembly. If each BTB is reliably connected, no voltage division is generated between any two serially connected detection pins in the detection circuit, and the output voltage of the detection circuit is the same as the input voltage at the moment. The reverse reasoning can be obtained, if the output voltage of the detection circuit is the same as the input voltage of the detection circuit, it is determined that no voltage drop is generated between any two detection pins connected in series in the detection circuit, and therefore it can be determined that each BTB is reliably connected.
If the determining unit 502 determines that the output voltage of the detecting circuit is different from the input voltage of the detecting circuit, it is determined that the BTB fastening is unreliable.
This is because, when the first plug assembly and the second plug assembly are not firmly fastened, the contact impedance between the first plug assembly and the second plug assembly changes, which is equivalent to that a resistor is connected in series between the two detection pins on the first plug assembly and the second plug assembly, and a voltage drop is formed between the two detection pins, so that the output voltage of the detection circuit is reduced compared with the input voltage. When the first plug assembly and the second plug assembly are not buckled, that is, the BTB formed by the first plug assembly and the second plug assembly is disconnected, the two detection pins on the first plug assembly and the second plug assembly are disconnected, so that the detection circuit cannot form a path, and the output voltage of the detection circuit is zero. The reverse deduction can be obtained, if the output voltage of the detection circuit is different from the input voltage of the detection circuit, the detection circuit judges that a broken circuit or a voltage drop exists between any two detection pins connected in series in the detection circuit, and therefore the BTB with unreliable buckling can be judged.
If the input end of the detection circuit is connected in series with the power supply network, the determining unit 503 is specifically configured to determine that the BTB fastening is unreliable if the output voltage is smaller than the input voltage of the detection circuit or the output voltage is zero.
If the input end of the detection circuit is connected in series with the power ground GND network, and the output end of the detection circuit is connected in series with the reference power supply and connected in series with the reference power supply through a preset resistor, the determination unit 503 is specifically configured to determine that the BTB fastening is unreliable if the output voltage is not zero.
The determining unit is specifically configured to, when an input power source connected in series to the detection circuit is a power supply network, determine that there is a disconnected BTB among the N BTBs if an output voltage of the detection circuit is zero.
The detection apparatus provided in the embodiment of the present invention is further configured to perform BTB fastening reliability detection on the terminal 30 provided in embodiment 3, and specifically includes: a determining unit 503, configured to determine that there is no BTB with unreliable fastening in the N BTBs if the determining unit 502 determines that the output voltage of the detection circuit is the same as the input voltage of the detection circuit. If the determining unit 502 determines that the output voltage of the detecting circuit is different from the input voltage of the detecting circuit, it is determined that the BTBs with unreliable buckling exist in the N BTBs.
It should be noted that the acquiring unit 501 in this embodiment may be implemented by being integrated in the detecting module 102, and the determining unit 502 and the determining unit 503 may be implemented by being integrated in the processor 103 of the detecting device 10, or may be stored in the memory 104 of the detecting device 10 in the form of program codes, and the processor 103 of the detecting device 10 calls the codes stored in the memory 104 of the detecting device to execute the functions of the determining unit 502 and the determining unit 503.
The detection device provided by the invention can detect whether the BTB device arranged on the terminal is not buckled (or buckled insecurely), and further can confirm whether the fault is caused by the BTB device when the terminal has the fault, so that the fault positioning efficiency is improved. Compared with the prior art, when the terminal has a fault, whether the fault is caused by a BTB device arranged in the terminal cannot be determined, and the fault positioning efficiency is improved.
