Description

Motherboard connector state detection method and system

The invention relates to a motherboard connector jumper state detecting method and system.

The current computer motherboard is usually provided with a connector jumper that can be set by the user. The jumper includes a plurality of pins disposed on the main board and a jumper cap for the user to set which pins are connected to each other. The Jumper is shown in Figure 4.

By setting the Jumper's different pin connections, it is possible to pull some signals high or low. To achieve this, the jumper cap needs to be placed in a specific location. For example, a Jumper with three pins in Figure 4 generally has three connection modes: pin A and pin B are connected, pin B and pin C are connected, and all pins are not connected; these three connections are respectively set by the jump cap D At stitch A and pin B, the jump cap D is placed on the stitch B, the stitch C, and the jump cap D is not used.

During the board inspection process, because the layout of each type of motherboard (the location of the jumper cap and the setting state of the jumper cap) are different, the current test plan requires the tester to check each motherboard one by one with the naked eye. The Jumper state (whether the jumper cap D is inserted, the jumper cap D is inserted on the stitch A, the stitch B or the stitch B and the stitch C). This kind of test method is cumbersome and prone to problems such as missed detection due to human error, and has a great negative impact on the quality of the product shipped.

In view of the above, it is necessary to provide a motherboard connector Jumper state detection method and system to realize automatic detection of the motherboard Jumper state.

The motherboard connector state detecting method includes the following steps: a reading step of: reading a voltage value of the voltage sensor; and a comparing step: comparing the read voltage value with a voltage value in the standard file, The current pin connection condition corresponding to the read voltage value is obtained; the determining step: determining whether the current pin connection condition is the same as the preset pin connection condition, and performing the correct prompt when the current pin connection condition is the same as the preset pin connection condition. Step, otherwise, perform the error prompting step; correct prompting step: display the correct prompt of the connector Jumper connection on the display device; error prompting step: display the prompt of the Jumper connection error on the display device.

The motherboard connector state detection system includes: a reading module for reading a voltage value of the voltage sensor; and a comparison module for reading the voltage value and the voltage value in the standard file The comparison is performed to obtain the current pin connection condition corresponding to the read voltage value; the determination module is configured to determine whether the current pin connection condition is the same as the preset pin connection condition; the correct prompt module is used to connect the current pin When the situation is the same as the pre-set pin connection, the correct prompt for connecting the connector Jumper is displayed on the display device; the error prompting module is used to connect the Jumper when the current pin connection is different from the preset pin connection. The wrong prompt is displayed on the display device.

Compared with the prior art, the motherboard connector state detecting method and system of the present invention reads the voltage value of the voltage sensor on the program circuit board when a carrier board and a program circuit board are introduced. The voltage value read is compared with the voltage value in the standard file to obtain the detection result of the motherboard Jumper state, thereby realizing the automatic detection of the motherboard Jumper state.

FIG. 1 is a schematic diagram of an operating environment of a preferred embodiment of a motherboard connector state detecting system of the present invention.

The Jumper5 is located on the motherboard to be tested. There are multiple Jumper5s on the motherboard to be tested (only one is shown), and each Jumper5 has multiple pins (only three pins are drawn on the figure). The carrier board sets the external pin 4 according to the situation of the Jumper 5 on the motherboard to be tested. Each set of external pins 4 on the carrier board corresponds to a Jumper 5 on the motherboard to be tested. The number of external pins included in each set of external pins 4 is determined by the number of pins included in Jumper 5 corresponding to the external pins 4 of the group. For example, if Jumper 5 includes three pins, then a set of external pins 4 corresponding to the Jumper has three external pins, and each external pin has a one-to-one correspondence with each pin of the Jumper 5.

When the detection of the Jumper5 state on the motherboard to be tested is required, the carrier board is placed above the motherboard to be tested. At this time, each set of external pins 4 is connected to a Jumper 5, wherein each external pin is connected to the Jumper 5 a pin. One end of each external pin of each set of external pins 4 on the carrier board is in one-to-one correspondence with the pins of Jumper 5, and the other end is connected to the circuit of the program board. Each external pin is connected to one end of the power supply in the circuit, or one end of the voltage sensor, and the other end of the power supply is connected to the other end of the voltage sensor. At the same time, the voltage sensor is connected to a single chip 1.

The preferred embodiment is described by taking Jumper 5 as three pins. As shown in Figure 1, the carrier board is placed above the motherboard to be tested. One end of each external pin on the carrier board is connected to one pin of the Jumper 5, and the other end of the external pin 4 on the carrier board is connected to the circuit of the program board. in. Wherein an external pin is connected to the negative terminal of the power supply Vc in the circuit, an external pin is connected to one end of the voltage sensor a in the circuit, and the last external pin is connected to the voltage sensor in the circuit At one end of b, the anode of the power source Vc is connected to the other ends of the voltage sensor a and the voltage sensor b. The voltage sensor a and the voltage sensor b are connected to the single chip microcomputer 1 through a specific port.

As shown in Figure 4, the Jumper 5 with three pins is located on the motherboard to be tested. The Jumper 5 has a pin A, a pin B, a pin C, and a jumper D. The Jumper5 has three connection methods: pin A and pin B are connected, pin B and pin C are connected, and all pins are not connected. These three connection methods are realized by placing the jump cap D on the stitch A and the stitch B, placing the jump cap D on the stitch B, the stitch C, and not using the jump cap D.

The motherboard connector state detecting system 10 operates in the single chip microcomputer 1, and the single chip microcomputer 1 is also connected to the display device 11. The display device 11 is configured to display a detection result of the state of the motherboard Jumper 5. The motherboard connector state detecting system 10 includes a reading module 100, a matching module 101, a determining module 102, a correct prompting module 103, an error prompting module 104, and a setting module 105. The function of each module will be described in detail in conjunction with the flowchart of FIG.

As shown in FIG. 3, it is a flowchart of a preferred embodiment of the motherboard connector state detecting method of the present invention.

In step S10, the reading module 100 reads the voltage value of the voltage sensor.

As shown in Figure 1, the schematic diagram of the motherboard Jumper operating environment, when the external pin 4 of the carrier board is connected to the Jumper5 pin of the motherboard to be tested, and the external pin 4 of the carrier board is connected to the circuit of the program circuit board, the reading module 100 reads the voltage value Va of the voltage sensor a and the voltage value Vb of the voltage sensor b.

In step S11, the comparison module 101 compares the read voltage value with the voltage value in the standard file, and obtains the current pin connection corresponding to the read voltage value.

The standard file is stored in a read-only memory (ROM, Read-Only Memory) of the single chip microcomputer 1. The voltage value in the standard file is set by the user according to the actual condition of the circuit on the program board.

As shown in Figure 1, the schematic diagram of the motherboard Jumper operating environment, when the external pin 4 of the carrier board is connected to the Jumper5 pin of the motherboard to be tested, and the external pin 4 of the carrier board is connected to the circuit of the program board, in the jump cap D (not shown in Figure 1) When pin A and pin B are placed, pin A and pin B are connected, and the circuit on the circuit board and the jumper corresponding to Jumper 5 pin A and pin B of the board to be tested are placed on the circuit board. The external pin and the circuit formed by the Jumper5 pin A and the pin B of the motherboard to be tested are turned on, the voltage value Va of the voltage sensor a is 0, and the pin B and the pin C of the Jumper 5 are not connected by the jump cap D, Then, the circuit on the circuit board, the two external pins corresponding to the Jumper5 pin B and the pin C of the motherboard to be tested, and the circuit formed by the motherboard to be tested, Jumper 5, pin B and pin C are disconnected, and the voltage sensor b The voltage value Vb is the voltage value of the power supply Vc on the program board. When the jumper cap D is placed on the stitch B and the stitch C, the voltage value Va of the voltage sensor a is the voltage value of the power source Vc on the circuit board, and the voltage value Vb of the voltage sensor b is 0. . When the jumper cap D is not used, it is equally reasonable that the voltage value Va of the voltage sensor a and the voltage value Vb of the voltage sensor b are the voltage values of the power source Vc on the program board.

For a schematic diagram of the motherboard Jumper operating environment as shown in FIG. 1, there is an example diagram of a standard file as shown in FIG. 5(1). 5(1), when the pin A and the pin B are connected, the voltage value Va is 0, and the voltage value Vb is Vc; when the pin B and the pin C are connected, the voltage value Va is Vc, and the voltage value Vb is 0; When the jump cap D is not used, the voltage value Va is Vc and the voltage value Vb is Vc.

For the example diagram shown in FIG. 5 (1), the comparison module 101 compares the read voltage value Va and the voltage value Vb with the voltage value Va and the voltage value Vb in the standard file to find a standard file. In the case of the same voltage value as the read voltage value, the connection condition corresponding to the same voltage value in this case is the current pin connection corresponding to the read voltage value. For example, when the read voltage value Va is 0 and the voltage value Vb is Vc, the comparison module 101 compares with the voltage value Va and the voltage value Vb in the standard file, and finds the standard file and reads. The voltage value of the same voltage value is: voltage value Va is 0, voltage value Vb is Vc, and the connection condition corresponding to the voltage value in the standard file is pin A and pin B connection, then pin A and pin B are connected for reading. The current pin connection corresponding to the taken voltage value.

For a schematic diagram of the motherboard Jumper operating environment as shown in FIG. 1, there is an example diagram of a standard file as shown in FIG. 5(2). As can be seen from Fig. 5 (2), when the pin A and the pin B are connected, the voltage value Va is 0, and the voltage value Vb is a value much larger than 0; when the pin B and the pin C are connected, the voltage value Va is much larger than 0. One value, the voltage value Vb is 0; when the jump cap D is not used, the voltage value Va is a value much larger than 0, and the voltage value Vb is a value much larger than 0.

For the example diagram shown in FIG. 5 (2), the comparison module 101 compares the read voltage value Va and the voltage value Vb with the voltage value Va and the voltage value Vb in the standard file to find a standard file. In the case of the same voltage value as the read voltage value, the connection condition corresponding to the same voltage value in this case is the current pin connection corresponding to the read voltage value. For example, when the read voltage value Va is 0 and the voltage value Vb is Vc, the comparison module 101 compares with the voltage value Va and the voltage value Vb in the standard file, and finds the standard file and reads. The voltage value is the same as the voltage value: the voltage value Va is 0, and the voltage value Vb is a value far greater than 0. In the standard file, the connection condition corresponding to the voltage value is pin A and pin B connection, then pin A, Pin B is connected to the current pin connection corresponding to the read voltage value.

In step S12, the determining module 102 determines whether the current pin connection situation is the same as the expected result. When the current pin connection condition is the same as the expected result, step S13 is performed, otherwise, step S14 is performed. The expected result refers to a pin connection situation preset by the user.

When the current pin connection condition is the same as the preset pin connection condition, the determination module 102 determines that the current pin connection condition is the same as the expected result. When the current pin connection situation is different from the preset pin connection condition, the determination module 102 determines that the current pin connection condition is different from the expected result.

It should be noted that before the state detection of the motherboard Jumper 5 to be tested, there is also a setting module 105 for receiving the user's setting for the expected result.

In step S13, the correct prompting module 103 displays the correct prompt of the Jumper 5 connection on the display device 11.

The Jumper5 is connected with the correct prompts, including the current pin connection of Jumper5, the expected result, and the correct connection of Jumper5.

In step S14, the error prompting module 104 displays a prompt of the Jumper5 connection error on the display device 11.

The Jumper5 connection error prompt, including Jumper5's current pin connection, expected results, Jumper5 connection error and other prompts.
