Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this hair
It is bright to be described in detail.Following disclosure provides many different embodiments or example is used to realize different knots of the invention
Structure.In order to simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relationship between various embodiments and/or setting is discussed.It should be noted that illustrated component is not necessarily to scale in the accompanying drawings
It draws.Present invention omits the descriptions to known assemblies and treatment technology and process to avoid the present invention is unnecessarily limiting.
As shown in Figure 1, a kind of method of judgement high speed connector installation failure of the invention, comprising the following steps:
S1, using the pin at high speed connector physics both ends as detection pin, for a pair of of high speed connector, by one height
The detection pin of fast connector is direct-connected, and another high speed connector two detects pin and is separately connected power supply and ground, by the detection pipe
Foot accesses test loop；
As shown in Fig. 2, by the physics both ends of the socket side (socket) of a pair of of high speed connector and plug side (plug)
Pin is Pin_A ' and Pin_Z ' as detection pin, the i.e. Pin_A and Pin_Z pin of socket side, corresponding plug side, will be examined
Test tube foot is respectively connected to test loop.Pin_A pin is connected in detection circuit as detection pin, which passes through 10K resistance
It is pulled upward to P3V3, the current-limiting resistance ground connection that Pin_Z passes through 100 Ω.The Pin_A ' and Pin_Z ' of plug side are direct-connected.
S2 will test circuit and connect with the one of another high speed connector detection pin, detected according to detection circuit
Level height, judges whether there is connecting fault.
Detection circuit can be connect with any detection pin of socket side: be will test circuit and connect with detection pin Pin_A
When, when detecting high level, then there are connecting faults for high speed connector；It will test circuit and connect with detection pin Pin_Z is surveyed
When, when detecting low level, there are ground faults for high speed connector.It is mentioned that high level, low level be relative value:
For detecting pin Pin_A, when high speed connector installation is good, forming circuit, the level at detection pin Pin_A is certain at this time
Voltage when failure is installed lower than high speed connector；Similarly for detecting pin Pin_Z, when high speed connector installation is good,
Forming circuit detects the voltage when level at pin Pin_Z is centainly higher than high speed connector installation failure at this time.
Such as Fig. 2, when plug side and socket side installation not in place, Pin_A and Pin_A ' and Pin_Z and Pin_Z ' pin
It does not contact, leads to entire circuit breaker, the detection circuit of socket end detects that the level of Pin_A pin is 3.3V high level
(because being pulled up by 10k resistance)；As good (such as Pin_Z and Pin_Z ') another end in contact of end thereof contacts it is bad (such as
Pin_A and Pin_A ') when, entire circuit is also open circuit, and what detection circuit detected is also high level.Only connector is installed to
Position, after Pin_A and Pin_A ' and Pin_Z and Pin_Z ' pin are contacted, the level on Pin_A pin just passes through on plug
Pin_A ' -- → Pin_Z ' -- → Pin_Z this link be pulled low.
Based on the above method, it may be implemented to multipair high speed connector while detecting: multipair high speed is connected
It connects device and is connected in same detection circuit and detected, the variation of pin level is detected by detecting each pair of high speed connector, it is fixed
Position failure high speed connector.
As shown in figure 3, Socket0~Socket7 is 8 high speed connector sockets, the installation to this 8 high speed connectors
Situation is detected simultaneously.Detection circuit uses band I2C (Inter-Integrated Circuit, parallel bus) BUS (total
Line) 8 mouthfuls of I/O (input/output, input/output) Expander chip, I/O mouth Pin00~Pin07 of chip is as inspection
Mouth is surveyed, for detecting the Pin_A level of Socket.Pin00 detects the Pin_A of Socket0, and Pin01 detects the Pin_ of Socket1
A ... and so on, Pin07 detects the Pin_A level of Socket7.I2C on the I2C and BMC of I/O Expander chip connects
Mouth is connected.
When high speed connector is installed in place, and pins contact is good, detected on 8 I/O mouthfuls of I/O Expander chip
Level be low level, when some connector does not install, on the I/O mouth of corresponding I/O Expander chip level become
For high level, triggering is interrupted, and is notified BMC, BMC to pass through the internal register of I2C bus access I/O Expander chip, is determined
The installation of which high speed connector is problematic in 0~7 this 8 high speed connectors.
It interrupts and is triggered by I/O expander chip, when I/O mouthfuls on I/O expander chip of level changes,
By the level change on the Interrupt pin of chip interior hardware circuit flip chip, Interrupt pin is connected to BMC
On a GPIO (General Purpose Input Output, universal input/output) mouth of chip, by this of BMC
GPIO mouthfuls are configured to Input (input) mouth.For convenience of description, it defines the Interrupt pin of I/O Expander chip and is somebody's turn to do
The signal transmitted between GPIO is " EXP_INT_BMC ".(connector does not have the I/O port of I/O Expander chip when event occurs
Connect, level from it is low become high when), Interrupt pin level becomes low from height, the level of the correspondence pin of such BMC
Also it can become low from height.One variable i is set in BMC, which changes according to the GPIO pin level change of BMC, electricity
It puts down when being high, variable i=1；When level is low, variable i=0.The BMC program wheel sequence variate-value, when this value is 0,
BMC is known that I/O Expander chip I/O pin, and event occurs, that is, has high speed connector not connect.BMC just leads in this way
The register for crossing I2C bus access Expander chip looks at it is which high speed connector does not connect.
The function of being similar to table, such as the following table 1, by the pin of IO Expander chip and company can be designed in BMC
The position for connecing device, which is done, to be mapped, in this way when BMC receives interruption, look over be I/O Expander chip that pin occur
Level change is known that the connector of that position goes wrong.After knowing that connector goes wrong, BMC passes through a little
The trouble light of bright system, and the failure logging is checked in the log of system for user.
Table 1
The above is the preferred embodiment of the present invention, for those skilled in the art,
Without departing from the principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also regarded as this hair
Bright protection scope.
