For example, in fig. 1 and fig. 2, there may be a plurality of pins connected between the card slot and the card slot detection circuit to realize the electrical connection between the card slot detection circuit and the card slot, so that the connection relationship between the two in the figures is a general representation. For another example, a connection line between the resistor module and the selection module in fig. 5 does not represent that the two are connected by only one pin, a connection line between the resistor module and the card slot does not represent that the two are connected by only one pin, one end of the resistor module is connected with at least one pin in the card slot, the other end of the resistor module is connected with at least one port of the selection module, the number of the at least one pin in the card slot is the same as that of the one port of the selection module, and the at least one pin in the card slot corresponds to the one port of the selection module.

However, in the case of many pins of the card slot, this method is very time-consuming and labor-consuming. For example, if the memory card slot has 288 pins, a great deal of labor cost and time cost will be wasted if the above-mentioned manual detection method is adopted. Therefore, the prior art has the problem of low card slot detection efficiency.

In view of the above, the present application provides a card slot detector, a method, an apparatus and a storage medium. The actual voltage of at least one pin of draw-in groove is gathered to draw-in groove detection circuitry among the draw-in groove detector to utilize the treater to compare the actual voltage of at least one pin with the voltage that prestores that corresponds respectively, in order to confirm the actual voltage of at least one pin and the numerical value size relation of the voltage that prestores that corresponds respectively, thereby whether determine the draw-in groove according to this numerical value size relation and break down.

In addition, the card slot detection circuit is substantially electrically connected with the pins in the card slot through the contact of the golden finger on the card slot detector and the pins in the card slot, so that the card slot detector in the application is connected to the main device in a non-fixed mode, and is electrically connected to the main device and detects the card slot of the main device. It should be noted that the connection between the processor and the card slot detection circuit in the card slot detector may be direct connection or indirect connection, for example, the indirect connection may be through a bus.

However, the detection result of this method is not accurate, because the tester with lamp can indicate the abnormal state of signal open circuit and short circuit of data line and address line by the on and off of the light-emitting diode, but it still has the disadvantage of low test coverage (only testing data and address line), and the disadvantage of being unable to judge whether the signal is abnormal by observing the brightness of the light-emitting diode by human eyes under the condition that the test line has micro short circuit or micro open circuit.

The.

The embodiment is substantially based on a more specific implementation of the card slot detector shown in fig. 5. In this embodiment of the application, the processor may select one data selector among the N data selectors by controlling the gating end of each data selector, so that the selected data selector starts to operate, then the processor inputs an address code through the address code end of the data selector, so that the data selector parses the received address code to acquire an actual voltage of a pin of the card slot indicated by the address code, and finally the data collector transmits the acquired actual voltage to the processor through the data output end, so that the processor determines whether the card slot is faulty according to the acquired actual voltage of the pin of the card slot.

For example, the processor inputs a high voltage to the gating ends Em0 of N data selectors to select the mth data selector, wherein m is greater than or equal to 1, and m is less than or equal to N; then the processor inputs a binary address code 010 to an address code end Am0/Am1/Am2 of the mth data selector, the mth data selector analyzes the two-level address code 010 to obtain a decimal 2, actual voltage of the (8 (m-1) + 3) th pin of the card slot is collected through a data input end Dm2 port indicated by the decimal 2, and the actual voltage is transmitted to the processor through a data output end Fm0, so that the processor determines whether the card slot is in fault according to the collected actual voltage of the pin of the card slot.

It should be noted that, in the above two embodiments, the connection between the processor and the card slot detection circuit is a direct connection. The direct connection can improve the efficiency of data transmission, simplify the internal structure of the card slot detector and further improve the efficiency of card slot detection.

It should be noted that, in order to better describe the technical solution of the present application, the present application adopts an eight-out-of-one data selector as an example for description, but the present application does not limit the type and the pin number of the data selector. Any type and pin count data selector may be meaningless used in the card slot test machine of the present application based on the above description, and thus a card slot test machine using any type and pin count data selector is within the scope of the present application.

In summary, the embodiment of the present application explains in detail the structure of the card slot detector on the basis of the foregoing embodiment, and further improves the efficiency of card slot detection.

The application also provides a card slot detection method, which is applied to a card slot detection device, wherein the card slot detection device can be a processor in the card slot detector in any one of the embodiments. Next, the present application will take the processor in the card slot detecting apparatus as an example, and with reference to the flowchart of fig. 8, a more detailed description will be given to the card slot detecting method. Specifically, the method comprises the following steps:

801: and acquiring the actual voltage of at least one pin of the card slot.

The processor in the card slot detector obtains the actual voltage of at least one pin of the card slot through a card slot detection circuit in the card slot detector. It should be noted that the actual voltage refers to the voltage of the pin of the card slot to be detected. The difference from a non-faulty card slot is that the voltage of the pins of the non-faulty card slot is a normal voltage. According to whether the card slot to be detected is in fault or not, the actual voltage of the card slot to be detected may not be consistent with the normal voltage of the card slot without fault, and may also be consistent.

It should be noted that the processor in the card slot detector may gate any number of data selectors in the selection module in the card slot detection circuit, and input an address code to the any number of data selectors, so as to obtain the actual voltage of the pin of the card slot indicated by the address code. Therefore, the method of the application can obtain the actual voltage of any one pin of at least one pin of the card slot through the card slot detection circuit.

In order to obtain the actual voltage of at least one pin of the card slot, the processor of the card slot detector may adopt a "sequential obtaining" mode or a "batch obtaining" mode. Next, the present application will explain these two modes in detail.

In the first "sequential acquisition" mode, a processor of the card slot detector sequentially gates all data selectors in a selection module in the card slot detection circuit, and sequentially inputs address codes into the gated data selectors according to the sequence of the address codes from large to small, so as to acquire actual voltages of pins corresponding to the address codes in the card slot.

For example, as shown in fig. 7, the processor of the card slot tester inputs a high voltage to the gating terminal E10 of the first data selector to gate the first data selector; then, 000, 001, 010, 011, 100, 101, 110, and 111 are sequentially input to the address code terminal a10/a11/a12 of the first data selector, so as to obtain the actual voltage of the 1 st pin and the 2 nd pin. After the actual voltage of the 1 st pin and the 2 nd pin.... 8 th pin of the card slot corresponding to the first data selector is sequentially obtained, the processor of the card slot detector sequentially obtains the actual voltage of the 9 th pin and the 10 th pin.. 16 th pin corresponding to the second data selector, and the actual voltage of the 8N-7 th pin and the 8N-6 th pin.. 8N-th pin corresponding to the Nth data selector is obtained finally.

In the second batch acquisition mode, a processor of the card slot detector gates all data selectors in a selection module in the card slot detection circuit at one time, and sequentially inputs address codes into all data selectors according to the sequence of the address codes from large to small, so as to simultaneously acquire actual voltages of corresponding pins of the same address code in the card slot in all data selectors.

For example, as shown in fig. 7, the processor of the card slot tester inputs a high voltage to the gating terminals E10, E20.... EN0 of the first and second data selectors, respectively, to gate the N data selectors; then, 000 are input to the address code terminal A10/A11/A12 of the first data selector, the address code terminal A20/A21/A22.. Of the second data selector, the address code terminal An0/An1/An2 of the Nth data selector, acquiring the actual voltage of the 1 st pin and the 9 th pin in the card slot through a data input end F10 of the first data selector and a data input end F20 of the second data selector respectively; according to the above-mentioned obtaining method, 001, 010, 011, 100, 101, 110, and 111 are sequentially input to the address code terminals of the N data selectors, so as to obtain the actual voltages of the remaining other pins of the card slot. Therefore, the same address code is input to all the data selectors at the same time, the actual voltage of the pins with the number consistent with that of the data selectors can be obtained, and the data obtaining efficiency is greatly improved.

802: and comparing the actual voltage of at least one pin with the corresponding pre-stored voltage respectively to determine the numerical value relationship between the actual voltage of at least one pin and the corresponding pre-stored voltage respectively.

The comparison refers to comparing the data of the pins respectively and independently, that is, comparing the actual voltage of the pins with the corresponding pre-stored voltage. The pre-stored voltage is used for indicating a normal voltage of at least one pin under the condition that the card slot has no fault, and can be understood as a normal voltage. Unlike the pre-stored voltage, the actual voltage may indicate a card slot failure or may indicate that the card slot is not failing. In order to obtain the pre-stored voltage of the pin, the card slot detector provided by the application can be inserted into a fault-free card slot so as to obtain the actual voltage of the fault-free card slot as the pre-stored voltage, and the pre-stored voltage is stored in the local memory.

For example, as shown in fig. 2, the card slot detecting apparatus is first inserted into the card slot 207 of the host device, the processor 202 in the card slot detecting apparatus obtains actual voltages of the pins in the card slot 207 through the card slot detecting circuit 201 and the gold finger 206, the memory 204 obtains pre-stored voltages corresponding to the pins of the card slot 207, and finally the actual voltages of the pins of the card slot 207 are respectively compared with the corresponding pre-stored voltages to determine whether the card slot 207 fails and the specific pin that fails.

803: and determining whether the card slot is in fault according to the numerical value size relation.

The step of determining whether the card slot is in fault according to the numerical value size relationship refers to determining that the pin is in fault and the card slot to which the pin belongs is in fault under the condition that the numerical value size difference between the actual voltage of the pin and the pre-stored voltage is large; and under the condition that the difference between the actual voltage of the pin and the value of the pre-stored voltage is small, judging that the pin has no fault, and determining that the card slot to which the pin belongs has no fault when all the pins of the card slot to which the pin belongs have no fault. To sum up, if all pins in the card slot have no fault, it is determined that the card slot has no fault, and if at least one pin in the card slot has a fault, it is determined that the card slot has a fault. Specifically, a difference value between the actual voltage of the pin and the pre-stored voltage is calculated, if the difference value is greater than a fault threshold value, a pin fault is determined, and the card slot to which the pin belongs is in fault, otherwise, the pin has no fault. The failure threshold value is a critical value used for indicating whether the card slot fails or not.

Optionally, when it is determined that the pin and the card slot are faulty, information indicating the fault of the card slot and the fault of the pin is sent to a display screen in the card slot detector, so that the display screen can display messages such as "card slot fault" and "x-th pin fault", where x is a positive integer not greater than the number of pins of the card slot.

For example, as shown in fig. 6, assuming that actual voltages obtained by a processor in the card slot tester to eight pins of the card slot are v1 and v2.. A.v 8, the processor obtains pre-stored voltages v1', v2'. A.v 8' corresponding to the eight pins of the card slot from a memory in the card slot tester, compares the magnitude relationship between v1 and v1' to determine whether the first pin of the card slot is faulty, compares v2 and v2' in sequence according to the comparison method, compares v3 and v3', and compares v8 and v8' to respectively compare whether the remaining 7 pins of the card slot are faulty. And if the 2 nd pin is in fault, sending a code 2 to a display screen of the card slot, so that the display screen displays characters such as 'card slot fault' and '2 nd pin fault'.

In summary, according to the card slot detection method provided by the application, the actual voltage of the at least one pin of the card slot is obtained and is compared with the corresponding pre-stored voltage respectively, so as to determine the numerical value relationship between the actual voltage of the at least one pin and the corresponding pre-stored voltage respectively, and determine whether the card slot is faulty or not according to the numerical value relationship. It can be seen that, because the technical scheme of this application has realized the automated inspection of draw-in groove, can detect a plurality of pins of draw-in groove moreover, consequently improved draw-in groove detection efficiency greatly.

The present application further provides another card slot detection method, where the card slot detection method is applied to a card slot detection apparatus, and the card slot detection apparatus may be a processor in the card slot detector in any one of the foregoing embodiments. Next, the present application will take the processor in the card slot detecting apparatus as an example, and with reference to the flowchart of fig. 9, a more detailed description will be given to the card slot detecting method. Specifically, the method comprises the following steps:

901: and acquiring the actual voltage of at least one pin of the card slot.

The processor in the card slot detector obtains the actual voltage of at least one pin of the card slot through a card slot detection circuit in the card slot detector. The implementation process of this step may refer to step 801 in the foregoing method embodiment, and details of this step are not described herein again.

902: and comparing the actual voltage of at least one pin with the corresponding pre-stored voltage respectively to determine the numerical value relationship between the actual voltage of at least one pin and the corresponding pre-stored voltage respectively.

The pre-stored voltage is used for indicating the normal voltage of at least one pin under the condition that the card slot has no fault. The implementation process of this step may refer to step 802 in the foregoing method embodiments, which is not described herein again.

It should be noted that, after the numerical value magnitude relationship between the actual voltage of each pin and the corresponding pre-stored voltage is determined, whether the card slot is faulty or not can be determined according to the numerical value magnitude relationship.

903: and determining the difference between the actual voltage of at least one pin and the corresponding pre-stored voltage respectively.

The actual voltage of each pin of the card slot is subtracted from the corresponding pre-stored voltage, and an absolute value is taken from a numerical value obtained by the subtraction, so that a difference value between the actual voltage of each pin and the corresponding pre-stored voltage is obtained.

904: a failure threshold is received.

The failure threshold value is a critical value used for indicating whether the card slot fails or not. The failure threshold may be obtained by manual input from a user. Next, the present application will describe the manual input mode of the user in combination with the card slot detector provided in the present application.

Illustratively, as shown in fig. 2, a processor 202 in the card slot tester receives a fault threshold value input by a user through an input device 203, and stores the fault threshold value in a memory 204, so that when the processor acquires an actual voltage of each pin of the card slot through a card slot testing circuit 201, whether each pin of the card slot is faulty or not is determined according to the fault threshold value stored in the memory 204 and a pre-stored voltage of each pin, and thus, whether the card slot to which the pin belongs is faulty or not is determined.

905: and if the difference value between the actual voltage of any one of the at least one pin and the corresponding pre-stored voltage is greater than the fault threshold value, determining that the card slot has a fault.

The processor of the card slot detector compares the difference value between the actual voltage of each pin and the corresponding pre-stored voltage with a fault threshold value respectively, and determines that the corresponding pin fails and the card slot to which the pin belongs fails under the condition that the difference value is greater than the fault threshold value; and determining that the corresponding pin has no fault when the difference value is less than or equal to the fault threshold value, and determining that the card slot to which the pin belongs has no fault when all the pins of the card slot to which the pin belongs have no fault.
