[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0047] Example 1:

[0048] To at least address the technical problems raised in this invention, embodiments of this invention provide a hardware wiring detection device.

[0049] Figure 1 This is a circuit diagram of a hardware wiring detection device provided in an embodiment of the present invention. It can connect to a control component and an external board, respectively. The hardware connection detection device is used to detect the wiring connection between the control component and the external board. (See reference...) Figure 1 The hardware wiring device provided in this embodiment of the invention may include: a forward signal conversion circuit 1, a wiring circuit 2, and a reverse signal conversion circuit 3. The input terminal of the forward signal conversion circuit 1 is connected to the control component A, and the output terminal of the forward signal conversion circuit 1 is connected to the input terminal of the wiring circuit. The forward signal conversion circuit 1 receives a trigger signal from the control component A and converts the trigger signal in a forward direction into a target format trigger signal. Each wiring circuit 2 includes two shorting points on an external board, and the wiring circuit is used to short-circuit the external board through the two shorting points. The output terminal of the wiring circuit 2 is connected to the input terminal of the reverse signal conversion circuit, and the output terminal of the reverse signal conversion circuit is connected to the control component. The reverse signal conversion circuit 3 converts the target format trigger signal passed through the wiring circuit in reverse direction into a return signal with the same trigger signal format, so that the control component A can determine the connection status between the control component and the external board based on the trigger signal and the return signal.

[0050] During hardware wiring testing, the hardware wiring testing device provided in this embodiment of the invention is connected to control component A and external board B respectively to detect the wiring connection between control component A and external board B. Wiring circuit 2 has a shorting point on the external board, which is shorted. In the specific hardware wiring testing process, control component A sends a trigger signal. The forward signal conversion circuit 1 in the hardware wiring testing device receives the trigger signal and converts it into a target format trigger signal. The target format trigger signal passes through wiring circuit B. The reverse signal conversion circuit 3 receives the target format trigger signal passed through the wiring circuit and converts it inversely into a return signal with the same format as the trigger signal. The return signal is sent to control component A. Control component A determines the wiring connection between the control component and the external board based on the trigger signal and the return signal.

[0051] In some embodiments, optionally, see [reference] Figure 1 The number of wiring circuits 2 is at least one; each wiring circuit has two shorting points on its external board, including: the shorting point of the wiring circuit input terminal and the shorting point of the wiring circuit output terminal; and the shorting point between the shorting point of the wiring circuit input terminal and the shorting point of the wiring circuit output terminal.

[0052] For example, the number of wiring circuits 2 can be set according to the wiring board to be tested. Before testing, the input terminal of the wiring circuit in each wiring circuit 2 is shorted and the output terminal of the wiring circuit is shorted.

[0053] In some embodiments, optionally, the number of external boards B shorted in each wiring circuit is at least one; when the number of external boards shorted in each wiring circuit is greater than one, each external board shorted in each wiring circuit is connected in series with each other.

[0054] For example, when performing hardware wiring tests, each wiring board can be tested individually, or, under special requirements, wiring boards connected in series can be tested as a whole.

[0055] In some embodiments, the forward signal conversion circuit 1 is optionally a voltage-to-current conversion circuit, and the reverse signal conversion circuit 2 is a current-to-voltage conversion circuit; the trigger signal received by the forward signal conversion circuit 2 from the control component A is a voltage pulse signal or a high / low level signal.

[0056] For example, control component A can be a control chip. Taking a voltage pulse signal as an example, the detection process is explained below, where the signal format refers to voltage or current. During hardware wiring detection, the control chip sends a voltage pulse signal as a trigger signal. The voltage-to-current conversion circuit converts the voltage pulse signal into a current signal. After the current signal passes through the wiring circuit, the current-to-voltage conversion circuit converts the current signal back into a voltage pulse signal as a return signal, which is sent back to control chip A. The current signal effectively reduces interference from external signals. The control chip compares the sent voltage pulse signal with the returned voltage pulse signal to determine whether the wiring connection between the corresponding terminal block and the control chip is abnormal. For example, if the sent voltage pulse signal and the returned voltage pulse signal are the same, it means that the connection between the corresponding terminal block and the control chip is normal; otherwise, it is abnormal.

[0057] Figure 2 A schematic diagram of a voltage-to-current conversion circuit provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of a current-to-voltage conversion circuit provided in an embodiment of the present invention.

[0058] See Figure 2 Operational amplifiers U1A and U2A are configured. Resistors R1, R2, R3, and R4 are placed on U1A. The first terminal of R1 is grounded, the second terminal is connected to the negative terminal of U1A, and the third terminal is connected to one end of R3. The other end of R3 is connected to one end of R4. One end of R2 is connected to the power supply VCC, and the other end of R2 is connected to the positive terminal of U1A, making U1A a single-inverting summing circuit. The other end of R4 is connected to one end of resistor L, and the other end of resistor L is connected to the positive terminal of multimeter XMM1, with the negative terminal of the multimeter grounded. The other end of R2 is also connected to one end of resistor R5 and one end of capacitor C1. The other ends of resistor R5 and capacitor C1 are both connected to the negative terminal of U2A, and the positive terminal of U2A is connected to the second terminal of resistor R4, making U2A a voltage follower. Negative feedback is introduced in both U1A and U2A. R1 = R2 = R3 = R4 = R. Based on the characteristics of virtual short and virtual open after the introduction of negative feedback, the voltage at U0 is obtained. Moreover, the resistance is known. Finally, it can be converted into current through I = U0 / R. Figure 2 This is a relatively mature voltage-to-current conversion circuit in the existing technology; the specific calculation process will not be elaborated here.

[0059] See Figure 3In current-to-voltage conversion circuits, an integrated operational amplifier can be configured to introduce voltage parallel negative feedback, enabling current-to-voltage conversion. For example, the negative terminal of operational amplifier U3A can be connected to one end of Rs and one end of R3, with the current at Rs being I1 and the current at R3 being I2. The positive terminal of U3A can be connected to one end of R2, with the other end of R2 grounded. The output terminal of U3A can be connected to one end of L1, with the other end of L1 grounded. Ideally, R3 = 0, therefore I1 = I2, and the output voltage UO = -I2 * R3. However, in practice, R3 is not zero, so the larger Rs is than R3, the higher the conversion accuracy. In the actual conversion process, a larger Rs can be set. Figure 3 This is a relatively mature current-to-voltage conversion circuit in the existing technology; the specific calculation process will not be elaborated here.

[0060] It is worth noting that, Figure 2 and Figure 3 This is an example of voltage-to-current conversion circuits and current-to-voltage conversion circuits, and is not intended to be limiting.

[0061] The hardware wiring detection device provided in this embodiment of the invention sets up a forward signal conversion circuit and a reverse signal conversion circuit between the control component and the external board, and sets a shorting point on the external board, so that the trigger signal sent by the control component is converted into a target format trigger signal. After the target format trigger signal passes through the wiring board, it is reversed back to a return signal with the same format as the trigger signal. This allows the control component to determine the wiring status of the corresponding wiring board based on the trigger signal and the return signal. The detection process is a circuit detection, which is convenient, fast and highly accurate.

[0062] Example 2:

[0063] Based on a general inventive concept, embodiments of the present invention also provide a hardware wiring detection system.

[0064] Figure 4 This is a schematic diagram of a hardware wiring detection system provided in an embodiment of the present invention. (See attached diagram.) Figure 4 The hardware wiring detection system provided in this embodiment of the invention includes: a control component A and a hardware wiring detection device C as described in any of the above embodiments. The control component A is connected to the input terminal of the forward signal conversion circuit 1 via a preset output port A1; the control component A is connected to the output terminal of the reverse signal conversion circuit 2 via a preset receiving port A2. The control component A is used to send a trigger signal to the hardware wiring detection device via the preset output port A1, and to receive a return signal with the same format as the trigger signal via the preset receiving port A2. Based on the trigger signal and the return signal, the connection status of the control component and the external board is determined.

[0065] The specific testing process of the hardware wiring testing system is described in the above-mentioned hardware wiring testing device embodiment, and will not be repeated here.

[0066] When making a connection, preset output port A1 and preset receiving port A2 are set in control component A, which are used to send a trigger signal and receive a return signal, respectively.

[0067] In some embodiments, optionally, the number of preset receiving ports A2 of the control component is the same as the number of wiring circuits 2, and each preset receiving port A2 of the control component is configured correspondingly to each wiring circuit 2 through an inverting signal conversion circuit 3. The control component can be connected to the main control board, and the number of preset receiving ports can be set according to the number of wires connected to the external boards of the main control board. Specifically, the user can plan and classify the wiring pins between the main control board and the external boards of the control component to determine the number of wires between the external boards of the main control board, thereby determining the corresponding number of preset receiving ports A2.

[0068] For example, pins for control components and headers can be reserved based on the number of external boards. A loop circuit can then be designed between the reserved control component pins and the inter-board headers. In the actual implementation, relevant programs can be pre-written and controlled by a host computer. If the wiring is correct, the corresponding detection circuit at the pin end will form a short-circuit closed loop. At this time, the data sent by the control component can be returned to the receiving end of the control component, and the received data signal can be analyzed to quickly troubleshoot the wiring.

[0069] For example, see Figure 4 Taking three wiring circuits as an example, the following explanation is provided. Each wiring circuit is connected to external boards B1, B2, and B3. The wiring circuit connected to external board B1 can be connected to the preset receiving port A21 of control component A via the reverse signal conversion circuit 3. The preset receiving port A21 is used to receive the return signal through wiring circuit B1. Similarly, the preset receiving port A22 is used to receive the return signal through wiring circuit B2, and the preset receiving port A23 is used to receive the return signal through wiring circuit B3.

[0070] In some embodiments, optionally, the control component is a control chip; the preset output port is a preset output pin; and the preset receiving port is a preset receiving pin.

[0071] The model of the control chip can be set according to requirements, which will not be elaborated here.

[0072] In this embodiment, the detection process of the hardware wiring detection system is described using five wiring circuits as an example. Each wiring circuit can be connected to an external board. For the detection loop of the first external board B1, X1 can represent the selected preset output pin, Y1 can represent the selected preset receiving pin, and X1 and Y1 are shorted. (X1, Y1) represents the detection result of external board B1. Similarly, X2 and Y2, X3 and Y3, X4 and Y4, X5 and Y5 are set, and (X2, Y2)(X3, Y3)(X4, Y4)(X5, Y5) represents the detection results of external boards B2, B3, B4, and B5. That is, h(n) represents the result of each loop, where n represents the number of loops, and n = 1, 2, 3, 4, 5. X1, X2, X3, X4, and X5 can be set to the same pin to emit the same trigger signal.

[0073] After all the short-circuit connections are completed, the control chip sends a set of high and low level pulse signals through different external board circuits.

[0074] Analyzing the first set of data according to the process h(1) = (X1, Y1), if the wiring is correct, the selected preset output pin and preset receiver pin in the first set form a loop, and the control chip will be able to receive the same data signal; otherwise, the wiring is incorrect. Similarly, the analysis results of h(2) = (X2, Y2), h(3) = (X3, Y3), h(4) = (X4, Y4), and h(5) = (X5, Y5) can be checked. Based on whether each set of data is the same, it can be determined whether the corresponding wiring is correct.

[0075] In some embodiments, optionally, it further includes: a display component; the display component is connected to the control component, and the display component is used to display the connection status of the control component and the external board wiring.

[0076] Optionally, a display component is provided for each preset receiving port.

[0077] Optionally, the display components include LED lights.

[0078] When a wiring error is detected, the corresponding faulty circuit can be displayed using a display component, such as an LED light. A red light will issue an alarm for a wiring error, while a green light will indicate that the connection is correct.

[0079] The hardware wiring detection system provided in this embodiment of the invention sets up a forward signal conversion circuit and a reverse signal conversion circuit between the control component and the external board, and sets a shorting point on the external board, so that the trigger signal sent by the control component is converted into a target format trigger signal. After the target format trigger signal passes through the wiring board, it is reversed back to a return signal with the same format as the trigger signal. This allows the control component to determine the wiring status of the corresponding wiring board based on the trigger signal and the return signal. The detection process is a circuit detection, which is convenient, fast and highly accurate.

[0086] The processes of sending and receiving signals described in steps S51 and S52 have been recorded in the above embodiments and will not be repeated in this embodiment; please refer to the above embodiments. When determining the connection status of the control component and the external board wiring based on the trigger signal and return signal, judgment conditions can be set according to requirements, and no specific limitations are made here.

[0087] In some embodiments, optionally, determining the connection status of the control component and the external board wiring based on the trigger signal and the return signal includes:

[0088] Determine if the trigger signal and the return signal are the same;

[0089] If the trigger signal and the return signal are different, the connection between the control component and the external board is determined to be an abnormal connection.

[0090] For example, the judgment condition can be set to whether the trigger signal and the return signal are the same. If they are not the same, it can be determined that the connection with the corresponding terminal block is an abnormal connection.

[0091] In some embodiments, optionally, the number of wiring circuits is at least one; receiving a return signal with the same format as the trigger signal includes: receiving a return signal returned through a different wiring circuit;

[0092] Based on the trigger and return signals, determine the connection status between the control component and the external board, including:

[0093] Determine if any return signal and trigger signal are the same. If any return signal and trigger signal are different, determine that the external board connection corresponding to the return signal is abnormal.

[0094] For example, when detecting the connection status with multiple external boards, if any return signal and trigger signal are different, it is determined that the external board corresponding to the corresponding return signal is abnormal.

[0095] In some embodiments, the trigger signal may be a voltage pulse signal or a high / low level signal.

[0096] The hardware wiring detection and control method provided in this embodiment sends a trigger signal; receives a return signal with the same format as the trigger signal; and determines the connection status of the control component and the external board based on the trigger signal and the return signal. By comparing the trigger signal and the return signal, the wiring status of the corresponding external board is determined, which is convenient, fast, and saves time.
