302, when being connected of 2 grades of signal pins in place on the second board and described the first board is in steady state (SS), described detection module in place judges that according to the situation of obtaining of 1,2 grade of signal in place the first board is whether in place or judge whether the second board is in place.
In one of application scenarios of reality, the first board in the embodiment of the present invention and the second board can be the relations of line card and backboard, and whether the present invention is in place mainly for detection of line card in this application scenarios.When the first board was line card, the second board was backboard, and namely whether main detection this moment the first board is in place, and detection module in place can be positioned on the first board, also can be positioned on the board outside the first board; When the first board was backboard, the second board was line card, and namely whether main detection this moment the second board is in place, and detection module in place can be positioned on the second board, also can be positioned on the board outside the second board.
In the Another Application scene of reality, the first board in the embodiment of the present invention and the second board can be the relations of master card and subcard, and whether the present invention is in place mainly for detection of subcard in this application scenarios.When the first board was subcard, the second board was master card, and namely whether main detection this moment the first board is in place, and detection module in place can be positioned on the first board, also can be positioned on the board outside the first board; When the first board was master card, the second board was subcard, and namely whether main detection this moment the second board is in place, and detection module in place can be positioned on the second board, also can be positioned on the board outside the second board.
Wherein, " the second board is in steady state (SS) with being connected of 2 grades of signal pins in place on described the first board " mainly refers to: the second board is fully to be connected with 2 grades of signal pins in place on the first board, and namely the second board and the first board are closely chimeric.In addition, in the present embodiment, " the second board is in steady state (SS) with being connected of 2 grades of signal pins in place on described the first board " also comprises: 2 grades of signal pins in place on the second board and the first board are fully unconnected.
Concrete, according to the second board, from the different of 2 grades of signal pin contiguities in place on the first board, can be divided into following three kinds of situations:
As shown in Fig. 4 a, the shell fragment 411 on the second board is not connected with 2 grades of signal pins 412 in place on the first board, and wherein, signal pin 413 in place is 1 grade of signal pin in place on the first board; As shown in Figure 4 b, shell fragment 421 on the second board is in critical conditions with being connected of 2 grades of signal pins 422 in place on the first board, the vibration that produces during due to the error of manufacture craft and board work, can cause the connection status of shell fragment 421 and 2 grades of signal pins 422 in place unstable, wherein, signal pin 423 in place is 1 grade of signal pin in place on the first board; As shown in Fig. 4 c, the shell fragment 431 on the second board fully is connected with 2 grades of signal pins 432 in place on the first board, and wherein, signal pin 433 in place is 1 grade of signal pin in place on the first board.
In the present embodiment, " the second board is in steady state (SS) with being connected of 2 grades of signal pins in place on described the first board " comprises the state shown in Fig. 4 a, Fig. 4 c at least.Under this two states, the extraneous factors such as vibration that produce when the error of manufacture craft and board work can not have influence on the result of obtaining of 2 grades of signals in place.Because 2 grades of signal pins in place are the hour hands on the first board, 2 grades of signal levels in place become low level by high level, so when detection module in place gets 2 grades of signals in place, the second board all fully is connected with the normal signal pin with 1 grade of signal pin on the first board, can determine that board is in place.
303, when being connected of 2 grades of signal pins in place on described the second board and described the first board plays pendulum, described detection module in place judges that according to the situation of obtaining of 1 grade of signal in place described the first board is whether in place or judge whether the second board is in place.
In the present embodiment, " the second board played pendulum with being connected of 2 grades of signal pins in place on the first board " comprises the state shown in Fig. 4 b at least.Under state shown in Fig. 4 b, shell fragment 421 on the second board is in critical conditions with being connected of 2 grades of signal pins 422 in place on the first board, in this state, the extraneous factors such as vibration that produce during due to the error of manufacture craft and board work, can cause the shell fragment 421 on the second board to play pendulum with being connected of 2 grades of signal pins in place on the first board, badly influence the result of obtaining of 2 grades of signals in place.With reference to Fig. 4 b, 2 grades of signal pins 422 in place be shorter in length than 1 grade of signal pin 423 in place; When the shell fragment 421 on the second board played pendulum with being connected of 2 grades of signal pins 422 in place, generally, the shell fragment 421 on the second board fully was connected with 1 grade of signal pin 423 in place.So in this case, 1 grade of signal level in place becomes low level by high level, detection module in place can get 1 grade of signal in place, and then definite board is in place.
The detection method that the board that the embodiment of the present invention provides is in place, be provided with 1 grade of signal pin in place and 2 grades of signal pins in place at least on the first board; When being connected of 2 grades of signal pins in place on the second board and the first board was in steady state (SS), detection module in place determined whether that according to the situation of obtaining of 1,2 grade of signal in place board is in place; When being connected of 2 grades of signal pins in place on the second board and the first board played pendulum, detection module in place determined whether that according to the situation of obtaining of 1 grade of signal in place board is in place.Concrete, when 2 grades of signal pins in place played pendulum with being connected of the second board (2 grades of signal pins in place are in critical conditions with being connected of the first board), the 1 grade of signal pin in place that is shorter in length than due to 2 grades of signal pins in place, so this moment, 1 grade of signal pin in place was connected with the second board is stable, detection module in place can be stablized and obtains 1 grade of signal in place, and then judges that board is in place.Compared with prior art, the board detection method in place that adopts the present embodiment to provide, when 2 grades of signal pins in place of the first board played pendulum with being connected of the second board, whether in place or judge whether the first board is in place according to detecting 1 grade of signal pin in place on the first board and being connected of the second board the second board, thereby improve accuracy and the reliability of board testing result in place, guarantee the normal operation of network service.
Embodiment bis-
On basis embodiment illustrated in fig. 1, further, the present embodiment provides the embodiment of a kind of board detection method in place.As shown in Figure 5, the method that provides of the present embodiment comprises:
501, at least two other signal pins in place of level are set on the first board, other signal pin in place of described at least two levels comprises 1 grade of signal pin in place and 2 grades of signal pins in place at least.
Wherein, described 1 grade of signal pin in place be shorter in length than the normal signal pin on described the first board, described 2 grades of signal pins in place be shorter in length than described 1 grade of signal pin in place.
502, when the second board being detected and 2 grades of signal pins in place on the first board contact, detection module in place obtains 2 grades of signals in place; When the second board being detected and 1 grade of signal pin in place on the first board contacts, detection module in place obtains states 1 grade of signal in place.
For example, as shown in Fig. 4 a, 2 grades of signal pins 412 in place on the shell fragment 411 on the second board and the first board are unconnected, and detection module in place can't obtain 2 grades of signals in place; As shown in Figure 4 b, the shell fragment 421 on the second board played pendulum with being connected of 2 grades of signal pins 422 in place on the first board, and detection module in place may intermittently obtain 2 grades of signals in place; As shown in Fig. 4 c, the shell fragment 431 on the second board fully is connected with 2 grades of signal pins 432 in place on the first board, and detection module in place can be stable obtains 2 grades of signals in place.
It is similar to the method for obtaining 2 grades of signals in place that detection module in place obtains the method for 1 grade of signal in place, and the specific implementation of detection module in place is prior art, repeats no more herein.
503, detect the second board and whether be in steady state (SS) with being connected of 2 grades of signal pins in place on the first board; If, execution step 504; If not, execution step 505.
Concrete, detection module in place can adopt following method performing step 503:
When detection module in place, in the Preset Time section, continue to get 2 grades of signals in place (situation shown in Fig. 4 c), when perhaps detection module in place continues to obtain less than 2 grades of signals in place (situation shown in Fig. 4 a) in the Preset Time section, determine that the second board and being connected of 2 grades of signal pins in place are in steady state (SS); Otherwise, determine that the second board and being connected of 2 grades of signal pins in place play pendulum.
504, when being connected of 2 grades of signal pins in place on the second board and the first board is in steady state (SS), if detection module in place gets 2 grades of signals in place, judges that the second board is in place or judge that the first board is in place; If detection module in place does not get 2 grades of signals in place, do not get 1 grade of signal in place yet, judge that the second board is not in place or judge that the first board is not in place; If detection module in place does not get 2 grades of signals in place, but get 1 grade of signal in place, judge that the second board is in place or judge that the first board is in place.
For example, as shown in Fig. 4 c, detection module in place gets 2 grades of signals in place, judges that the second board is in place or judges that the first board is in place; As shown in Fig. 4 a, detection module in place does not get 2 grades of signals in place, may not obtain 1 grade of signal in place yet, judges that the second board is not in place or judges that the first board is not in place.Between Fig. 4 a and Fig. 4 b, detection module in place does not get 2 grades of signals in place, but gets 1 grade of signal in place, judges that the second board is in place or judges that the first board is in place.
505, when being connected of 2 grades of signal pins in place on the second board and the first board plays pendulum, if detection module in place gets 1 grade of signal in place, judge that the second board is in place or judge that the first board is in place; If detection module in place obtains less than 1 grade of signal in place, judge that the second board is not in place or judge that the first board is not in place.
For example, as shown in Figure 4 b, detection module in place gets 1 grade of signal in place, judges that the second board is in place or judges that the first board is in place.
What deserves to be explained is, generally, due to the length that is shorter in length than 1 grade of signal pin in place of 2 grades of signal pins in place, so when the second board played pendulum with being connected of 2 grades of signal pins in place, the first board was fully to be connected with 1 grade of signal pin in place.
Preferably, after step 505, can also comprise:
506, the alarm signal of 2 grades of abnormal signals in place of detection module output in place, described alarm signal is for pointing out the user to check board.
By step 506, can be under the prerequisite that does not affect the communication facilities operation, reminding user checks board, guarantees that the second board fully is connected with 2 grades of signal pins in place on the first board, avoids because board is loosening, causing occurring communication failure.
What deserves to be explained is, as a kind of improvement project, in the present embodiment, on the first board, same other signal pin in place of level comprises one or more signal pins in place, and namely same other signal pin in place of level can have one or more.Adopt such scheme, can avoid the crooked problem that causes signal error detection in place because of board.
It is emphasized that, in the present embodiment, arbitrary board in the first board and the second board can be used as function line card (such as fot router, switch board etc.), another board is as the draw-in groove on rack-mount unit, perhaps the arbitrary board in the first board and the second board can be used as the master card (such as fot router, switch board etc.) of function line card, another board is as the subcard of function line card master card on rack-mount unit, and the present embodiment is not done restriction.
