As shown in fig. 1, an embodiment of the present invention provides a detection apparatus, which is used for detecting a device under test. The device to be tested comprises a first detection port and a second detection port, and the device to be tested is used for generating a signal to be tested. The detection device includes: the device comprises an interface module 100, a connection detection module 200, a feedback module 300 and a device detection module 400. The interface module 100 is used for being electrically connected with the first detection port and the second detection port respectively; the connection detection module 200 is configured to be electrically connected to the interface module 100, the connection detection module 200 is configured to generate a connection detection signal, and the connection detection module 200 is further configured to receive a start detection signal and switch a first conduction state according to the start detection signal; the feedback module 300 is configured to be electrically connected to the interface module 100, the feedback module 300 is configured to perform a feedback operation according to the connection detection signal, and the feedback module 300 is further configured to receive a start detection signal and switch a second conduction state according to the start detection signal; the device detection module 400 is configured to be electrically connected to the interface module 100, and the device detection module 400 is configured to generate a detection result according to the first conduction state, the second conduction state, and the signal to be detected.

Specifically, the interface module 100 is respectively connected to a first detection port and a second detection port of the device to be tested, and the first detection port and the second detection port of the device to be tested are two communication ports corresponding to the functions to be tested. The interface module 100 is further electrically connected to the docking detection module 200, the feedback module 300, and the device detection module 400, respectively, wherein the feedback module 300 and the device detection module 400 are connected in parallel. The connection detection module 200 generates a connection detection signal, when the interface module 100 is not correctly connected to the first detection port and the second detection port, respectively, a current loop cannot be formed between the connection detection module 200 and the feedback module 300, the feedback module 300 cannot receive the connection detection signal, and the feedback module 300 cannot perform feedback, so that the connection detection signal indicates that the interface module 100 is not correctly connected to the first detection port and the second detection port; when the interface module 100 is correctly connected to the first detection port and the second detection port, respectively, the feedback module 300 can receive the connection detection signal and perform a feedback operation according to the connection detection signal, so as to indicate that the interface module 100 is correctly connected to the first detection port and the second detection port, respectively.

After the interface module 100 is correctly connected to the first detection port and the second detection port, the connection detection module 200 and the feedback module 300 both receive a start detection signal, which may be an electrical signal sent by a control module such as a computer host. After receiving the start detection signal, the docking detection module 200 and the feedback module 300 are both switched from on to off. At this time, the device detection module 400 may receive the signal to be detected generated by the device to be detected, and detect the signal to be detected to generate a detection result, so as to determine whether the function of the device to be detected can normally operate.

According to the detection device of the embodiment of the present invention, after the connection detection module 200 generates the connection detection signal, if the feedback module 300 receives the connection detection signal, it indicates that the interface module 100 can be correctly connected to the first detection port and the second detection port, and at this time, the feedback module 300 performs the feedback operation. The device to be detected generates a signal to be detected, and when the interface module 100 is correctly connected to the first detection port and the second detection port, the connection detection module 200 and the feedback module 300 are both turned off according to the start detection signal, so that the device detection module 400 can start detection operation on the signal to be detected. The detection apparatus of this embodiment can determine whether the interface module 100 is correctly connected to the first detection port and the second detection port by whether the feedback module 300 has feedback, so as to improve the efficiency of connection determination, thereby improving the detection efficiency of the device to be detected.

As shown in fig. 2, in some embodiments of the invention, the interface module 100 includes: a first probe J1, a second probe J2, a third probe J3, and a fourth probe J4. The first probe J1 is used for being electrically connected with one end of the feedback module 300 and one end of the device detection module 400 respectively, and the first probe J1 is used for being connected with the first detection port; the second probe J2 is used for being electrically connected with the other end of the feedback module 300 and the other end of the device detection module 400 respectively, and the second probe J2 is used for being connected with a second detection port; the third probe J3 is used for being electrically connected with one end of the connection detection module 200, and the third probe J3 is used for being connected with the first detection port; the fourth probe J4 is used for electrically connecting with the other end of the connection detection module 200, and the fourth probe J4 is used for connecting with the second detection port.

Specifically, the first probe J1 is electrically connected to one connection node between the feedback module 300 and the device inspection module 400, and the second probe J2 is electrically connected to the other connection node between the feedback module 300 and the device inspection module 400. The first probe J1 is connected with a first detection port of the device to be detected, and the second probe J2 is connected with a second detection port of the device to be detected. The connection detection module 200 is electrically connected to the third probe J3 and the fourth probe J4, respectively, where the third probe J3 is connected to a first detection port of the device to be detected, and the fourth probe J4 is connected to a second detection port of the device to be detected. The first probe J1 and the third probe J3 can be fixed together by a fixing piece, and a gap exists between the first probe J1 and the third probe J3 (namely, the first probe J1 does not contact with the third probe J3); the second probe J2 and the fourth probe J4 can be fixed together by another fixing member, and a gap exists between the second probe J2 and the fourth probe J4.

After the connection detection module 200 generates a connection detection signal, if the first probe J1 and the third probe J3 are not correctly connected to the first detection port, and/or the second probe J2 and the fourth probe J4 are not correctly connected to the second detection port, a current loop cannot be formed between the connection detection module 200 and the feedback module 300, that is, the feedback module 300 cannot receive the connection detection signal generated by the connection detection module 200, and at this time, the feedback module 300 cannot perform a feedback operation. If the first probe J1 and the third probe J3 can be correctly connected to the first detection port, and the second probe J2 and the fourth probe J4 can also be correctly connected to the second detection port, a current loop can be formed between the connection detection module 200 and the feedback module 300, that is, the feedback module 300 can receive a connection detection signal, and the feedback module 300 performs a feedback operation according to the connection detection signal.

As shown in fig. 2, in some embodiments of the invention, the docking detection module 200 includes: a power supply unit 210 and a first switch unit 220. One end of the power supply unit 210 is used for electrically connecting with the fourth probe J4, and the power supply unit 210 is used for generating a docking detection signal; the first switching unit 220 is used to be electrically connected to the other end of the power supply unit 210 and the third probe J3, respectively, and the first switching unit 220 is used to be turned off according to the start detection signal.

Specifically, the power supply unit 210 is electrically connected to the fourth probe J4 and one end of the first switch unit 220, respectively, and the other end of the first switch unit 220 is electrically connected to the third probe J3. The first switch unit 220 is in a normally closed state before receiving the start detection signal. The power supply unit 210 is configured to generate a connection detection signal, for example, referring to fig. 2, the power supply unit 210 may be a battery, a positive electrode of the battery is electrically connected to the first switch unit 220, a negative electrode of the battery is electrically connected to the fourth probe J4, and a power supply voltage provided by the battery is the connection detection signal. When the first probe J1 and the third probe J3 are not correctly connected to the first detection port, and/or the second probe J2 and the fourth probe J4 are not correctly connected to the second detection port, a current loop cannot be formed between the power supply unit 210 and the feedback module 300, that is, the feedback module 300 cannot receive a connection detection signal of the power supply unit 210, and at this time, the feedback module 300 cannot perform a feedback operation. When the first probe J1 and the third probe J3 can be correctly connected to the first detection port, and the second probe J2 and the fourth probe J4 can also be correctly connected to the second detection port, a current loop can be formed between the power supply unit 210 and the feedback module 300, that is, the feedback module 300 can receive a connection detection signal, and at this time, the feedback module 300 performs a feedback operation according to the connection detection signal. The first switch unit 220 is switched to an off state after receiving the start detection signal, so as to ensure that the device detection module 400 is not affected by the connection detection signal generated by the power supply unit 210 when detecting the signal to be detected.

As shown in fig. 2, in some embodiments of the invention, the feedback module 300 comprises: a light emitting member 310 and a second switch unit 320. The light-emitting member 310 is used for being electrically connected with the second probe J2, and the light-emitting member 310 is used for performing light-emitting operation according to the connection detection signal; the second switch unit 320 is used for being electrically connected with the light emitting member 310 and the first probe J1, respectively, and the second switch unit 320 is used for being turned off according to the start detection signal.

Specifically, the light emitting element 310 is electrically connected to the second probe J2 and one end of the second switch unit 320, respectively, and the other end of the second switch unit 320 is electrically connected to the first probe J1. The second switch unit 320 is in a normally-off state before receiving the start detection signal. When the first probe J1 and the third probe J3 are not correctly connected to the first detecting port, and/or the second probe J2 and the fourth probe J4 are not correctly connected to the second detecting port, a current loop cannot be formed between the power supply unit 210 and the light emitting element 310, that is, the light emitting element 310 cannot receive the connection detecting signal of the power supply unit 210, and at this time, the light emitting element 310 cannot perform a light emitting operation. When the first probe J1 and the third probe J3 can be correctly connected to the first detection port, and the second probe J2 and the fourth probe J4 can also be correctly connected to the second detection port, a current loop can be formed between the power supply unit 210 and the light-emitting member 310, that is, the light-emitting member 310 can receive a connection detection signal, and at this time, the light-emitting member 310 performs a light-emitting operation according to the connection detection signal. The second switch unit 320 is switched to an off state after receiving the start detection signal, so as to ensure that the device detection module 400 is not affected by the current loop between the power supply unit 210 and the light emitting element 310 when detecting the signal to be detected.

As shown in fig. 2, in some embodiments of the present invention, the first switching unit 220 includes a first relay, and the second switching unit 320 includes a second relay.

Specifically, before receiving the start detection signal, the first relay is in a normally closed state, so that the docking detection signal generated by the power supply unit 210 can pass through the first relay. Meanwhile, the second relay is also in a normally closed state, so that the light emitting element 310 and the power supply unit 210 can form a current loop, and thus the light emitting element 310 can receive the connection detection signal when the probe is correctly connected. After the first relay and the second relay receive the start detection signal, both the first relay and the second relay are switched to an off state, so that the device detection module 400 is not affected by a current loop between the power supply unit 210 and the light emitting element 310 when detecting the signal to be detected.

In some embodiments of the present invention, the light emitting member 310 includes at least one LED.

Specifically, the light emitting member 310 may include at least one LED. When the light emitting member 310 includes only one LED, for example, referring to fig. 2, the LED is directly electrically connected to one end of the second relay and the second probe J2, respectively. When the light emitting member 310 includes a plurality of LEDs, the plurality of LEDs may be connected in series with each other or in parallel with each other. It can be understood that the number of the specific arrangement of the LEDs and the connection mode can be adaptively selected according to actual requirements.

As shown in fig. 3, an embodiment of the present invention further provides a detection system, where the detection system includes: a control module 600, such as the detection apparatus 500 described in any of the above embodiments. The control module 600 is configured to be electrically connected to the connection detection module and the feedback module, respectively, and the control module is configured to generate a start detection signal.

Specifically, referring to fig. 2 and 3, the control module 600 is electrically connected to the first relay of the docking detection module 200 and the second relay of the feedback module 300, respectively. The control module 600 controls the on-state of the first relay and the second relay respectively by starting the detection signal, so as to ensure that the device detection module 400 is not affected by the current loop between the power supply unit 210 and the light emitting element 310 when detecting the signal to be detected.

It can be seen that the contents in the foregoing detection apparatus embodiments are all applicable to the embodiments of the detection system, and the functions specifically implemented by the embodiments of the detection system are the same as those of the embodiments of the detection apparatus, and the beneficial effects achieved by the embodiments of the detection apparatus are also the same as those achieved by the embodiments of the detection apparatus.

In some embodiments of the invention, the detection system further comprises a display module. The display module is used for being electrically connected with the equipment detection module and is used for displaying operation according to the detection result.

Specifically, after the device detection module generates the detection result, the detection result is displayed through the display module, so that whether the function of the device to be detected can normally operate or not can be intuitively judged.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
