It should be noted that the working principle of the memory slot in this embodiment is as follows: firstly, the existing memory slot has 144 pairs of contacts, and the 144 pairs of contacts are used for contacting with a gold finger of the memory bank 11 to realize the conduction of a circuit and the transmission of signals, so as to be used for the subsequent test of the performance of the memory bank 11; on the basis of the conventional slot, two pairs of contacts are added at two ends of the slot, each pair of contacts is in an off state (that is, contact ends of the first contact 4 and the second contact 5 are not in contact) when the memory bank 11 is not inserted into the slot, and the first contact 4 is pressed to make the first contact 4 and the second contact 5 in a contact closed conduction state after the memory bank 11 is inserted, and the conduction positions of the first contact 4 and the second contact 5 are set to be in a conduction state when the memory bank 11 is just inserted in place, so that the mainboard 12 can receive a conduction signal to know that the current memory bank 11 is inserted in place, and the memory plugging and unplugging device can be controlled to stop inserting the memory bank 11, thereby preventing the memory bank 11 from being inserted too deeply and shortening the service life of the memory slot, and prolonging the service life of the memory slot.
Based on the disclosure, in the embodiment, at least one pair of memory plugging detection contacts 3 is additionally arranged at two ends of the slot respectively, and each memory plugging detection contact includes a first contact 4 and a second contact 5, and a contact end of the first contact 4 is pressed by the memory bank and can be in contact conduction with a contact end of the second contact 5, where the conduction position of the two contact ends is a position where the memory bank is pressed down to a proper position, so that when the memory bank 11 presses down the contact end of the first contact 4 to make the contact end of the first contact 4 in contact conduction with the contact end of the second contact 5, it can be determined that the memory bank is pressed down to a proper position through a conduction signal, and plugging and unplugging are stopped, so that the memory slot and the memory bank 11 can be prevented from being damaged.
As shown in fig. 5, in a second aspect, the present invention provides a memory plugging control system, including the memory slot described in any one of the possible designs of the first aspect, further including an automatic memory plugging device 10, a memory bank 11, and a motherboard 12, where the motherboard 12 is provided with a controller 13, the memory slot is electrically connected to the motherboard 12, and the automatic memory plugging device 10 is electrically connected to the controller 13;
when the automatic memory plugging/unplugging device 10 inserts the memory bank 11 into the memory slot and the first contact 4 and the second contact 5 are in contact conduction, the controller 13 sends a control signal to the automatic memory plugging/unplugging device 10, so that the automatic memory plugging/unplugging device 10 stops inserting the memory bank 11.
In a specific embodiment, the main board 12 is provided with at least two pairs of pin connection contacts, each pair of pin connection contacts being adapted to be connected to the pin end 6 of the first contact 4 and the pin end 6 of the second contact 5, respectively.
Based on the disclosure, in this embodiment, when the automatic memory plugging device 10 inserts the memory bank 11 into the memory slot and the first contact 4 and the second contact 5 are in contact conduction, the controller 13 sends a control signal to the automatic memory plugging device 10, so that the automatic memory plugging device 10 stops inserting the memory bank 11.
In addition, in order to solve the basic problem that the efficiency of the memory test is greatly affected because the reasons that the memory cannot pass the test can not be distinguished in the prior art but only the memory bank 11 can be retested, the embodiment further provides a working method of the memory plugging control system for solving the above problem, and the method is specifically described below.
As shown in fig. 6, in a third aspect, the present invention provides a working method of the memory plugging control system according to any one of the possible designs of the second aspect, including but not limited to the following steps S1 to S2:
s1, inserting a memory bank 11 into a memory slot through automatic memory plugging equipment 10, and enabling a first contact 4 and a second contact 5 to be in contact conduction;
specifically, the automatic memory plugging device 10 holds the memory bank 11 and inserts the memory bank into the memory slot, and when the memory bank 11 is pressed to a certain position, the memory bank is abutted against the contact end of the first contact 4, so that the contact end of the first contact 4 is pressed to be in contact with the contact end of the second contact 5 for conduction.
And S2, when the contact loop is conducted, the memory bank 11 is considered to be inserted in place, and a first control signal is sent to the automatic memory plugging and unplugging device 10 through the controller 13, so that the memory bank 11 stops being pushed down and inserted, and the memory bank 11 and the memory slot are prevented from being damaged due to the fact that the memory bank 11 is pushed down excessively.
In a specific embodiment, the method further comprises:
s3, after the action of inserting the memory bank 11 once is finished, calculating the time difference of the loop conduction of the two pairs of memory plugging detection contacts 3 in the memory slot through the controller 13;
s4, if the time difference of the conduction of the two loops is larger than the time difference threshold value, judging that the posture of the memory bank 11 is inclined in the current memory plugging action;
and S5, sending a second control signal to the automatic memory plugging device 10 through the controller 13 so as to stop the automatic memory plugging device 10.
Preferably, after sending the second control signal to the automatic memory plugging device 10 through the controller 13, the method further includes:
the controller 13 sends out a first alarm signal to give an alarm prompt.
Specifically, in the process of pressing down the memory bank 11, if there is a posture tilt or deviation, one end of the memory bank 11 may be caused to press down the memory plugging detection contact 3 to a preset position first, so as to implement the contact loop conduction, therefore, by detecting the time difference of the contact loop conduction at the two ends, when the time difference is greater than the threshold value x sec (x is a positive rational number, and the value of x is determined by the slot historical plugging data), it is determined that there is a tilt or deviation in the posture of the memory bank 11, and thus there is a possibility that the memory bank 11 is in poor contact with the slot, even the memory bank 11 and the memory slot are damaged, so that the controller 13 needs to control the automatic memory plugging device 10 to stop plugging and unplugging operations, and give an alarm in time, so as to remind an operator to take measures in time.
In a specific embodiment, the method further comprises:
s6, after the action of inserting the memory bank 11 for the first time is finished, acquiring a downward pressure curve of the action of inserting the memory bank for the second time through the controller 13, and comparing the downward pressure curve with a standard downward pressure curve and a downward pressure curve of the action of inserting the memory bank 11 for at least one time before respectively;
s7, if the downward pressure curve of the action of inserting the memory bank 11 the next time exceeds the range of the standard downward pressure curve and the deviation value between the downward pressure curve of the action of inserting the memory bank 11 the last time is larger than the deviation value threshold value, judging that the memory bank 11 has posture inclination or deviation in the action of inserting the memory bank the next time; wherein, the deviation threshold value can be y%, y is a positive rational number, and the value of y is determined by the slot historical data;
it should be noted that, in the testing process, there may be two reasons for the downward pressure curve of the memory stick 11 exceeding the standard downward pressure curve range, one is curve deviation caused by aging of the memory slot itself, and the other is curve deviation caused by irregular insertion and removal of the memory stick 11, so that the downward pressure curve of the memory stick 11 that is inserted at the time needs to be compared with the downward pressure curve of at least one previous action, so as to determine the reason for the curve deviation.
And S8, judging the possibility of aging of the memory slot if the downward pressure curve of the action of inserting the memory bank 11 for the second time exceeds the range of the standard downward pressure curve and the deviation between the downward pressure curve of the action of inserting the memory bank 11 for the last time is not greater than the deviation threshold.
In a specific embodiment, the method further comprises:
and S9, if the downward pressure curve of the memory inserting action for a plurality of times exceeds the range of the standard downward pressure curve, and the deviation between the downward pressure curve of the memory inserting action each time and the downward pressure curve of the last memory inserting action 11 is not more than a first deviation threshold, judging that the memory slot is aged.
In a specific embodiment, when determining the likelihood of aging or having aged the memory socket, the method further comprises:
the controller 13 sends out a first alarm signal to prompt an alarm, and commands the automatic memory plugging device 10 to stop working.
For example, if the situation occurs z times (z is a positive integer, and the value of z is determined by the actual data of the slot), it is considered that the memory slot is aged, and it is necessary to possibly damage or influence the memory test at any time, and at this time, the automatic plugging device should be immediately suspended from working and an alarm should be given.
It should be noted that the plugging/unplugging state of the memory bank is obtained according to the comparison result, that is, whether there is a posture inclination, whether the slot is aged, and whether there is a problem in the memory plugging action, if there is the problem, an operator may be notified to repair the problem, and the memory bank test is stopped before the repair is completed. Therefore, in the memory test, if the memory test is wrong and the slot system does not find abnormality, the possibility of poor contact between the memory bank and the slot can be eliminated, and the problem is positioned in the memory bank; if the memory test is wrong and the slot system considers that the slot is likely to be aged, manual detection or repeated test is needed; if the slot system is in other state, the memory test will not be performed. Therefore, the method can eliminate one of the error possibilities for the memory test, thereby reducing the times of repeated tests and improving the test efficiency.
Finally, it should be noted that: the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
