[0031] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings rather than all the structures.

[0032] Figure 1 It is a schematic structural diagram of a vehicle ceiling wiring harness detection device provided by an embodiment of the present invention, refer to Figure 1 . An embodiment of the present invention provides a vehicle ceiling wiring harness detection device, including:

[0033] A controller (not shown in the figure);

[0034] An identity recognizer 1, which is used to obtain the harness assembly identity information of the harness to be tested and the electronic component identity information of the electronic components in the harness to be tested;

[0035] At least two detection instruments 2, which are used to obtain the characteristic information and parameter information of the electronic components;

[0036] Wherein, the controller is configured to receive the harness assembly identity information, the electronic component identity information and the characteristic information of the electronic components, and determine whether the harness to be tested is assembled normally according to the harness assembly identity information, the electronic component identity information and the characteristic information of the electronic components. If so, it determines whether the harness to be tested is qualified according to the parameter information of the electronic components and the qualified range of the parameters of the electronic components.

[0037] Among them, the controller is used to control the detection instrument 2 to detect the wire harness to be tested, receive the identification result of the identity recognizer 1, and judge whether the wire harness to be tested is qualified by integrating the results of the detection instrument 2 and the identity recognizer 1. The embodiment of the present invention does not limit the specific type of the controller, as long as it can meet the above functions. Exemplarily, the controller can be a programmable logic controller (PLC), or a microcontroller unit (MCU) and the peripheral circuits required to implement the corresponding functions. The identity recognizer 1 is used to identify the identity information of the wire harness to be tested and the identity information of the electronic components. Exemplarily, the identity recognizer 1 includes a barcode scanner 11, and the barcode scanner 11 is used to scan the QR code or barcode of the wire harness to be tested, as well as the QR code or barcode of the electronic components. The QR code or barcode of the wire harness to be tested carries the wire harness assembly identity information, and the QR code or barcode of the electronic components carries the electronic component identity information. The barcode scanner 11 obtains the electronic component identity information and the wire harness assembly identity information by acquiring the QR code. Alternatively, the identity recognizer 1 includes a near-field communication (NFC) reader, and the near-field communication reader is used to read the near-field communication tag of the wire harness to be tested, as well as the near-field communication tag of the electronic components. The near-field communication tag of the wire harness to be tested carries the wire harness assembly identity information, and the near-field communication tag of the electronic components carries the electronic component identity information. The near-field communication reader obtains the electronic component identity information and the wire harness assembly identity information by acquiring the information in the near-field communication tag. The detection instrument 2 is used to obtain the characteristic information and parameter information of the electronic components. Therefore, the type of the detection instrument 2 can be determined according to actual needs. The electronic components can include microphones, speakers, reading lights, etc. Exemplarily, the detection instrument 2 can include a voltmeter, an ammeter or an ohmmeter. The device can also include an operation button 4 for inputting control instructions. The characteristic information of the electronic components can include physical quantities related to the electrical characteristics of the electronic components themselves, such as the resistance value of the electronic components. Through the electronic component identity information, the range of characteristic parameters that the electronic components should have can be confirmed. By comparing the measured characteristic information of the electronic components with the range of characteristic parameters that the electronic components should have, it can be verified whether the actual electronic components in the wire harness to be tested are consistent with the electronic component identity information. If they are not consistent, it means that the electronic components are assembled incorrectly and the wire harness to be tested is unqualified. If they are consistent, it is further verified whether the electronic component identity information and the wire harness assembly identity information correspond. If they do not correspond, it means that the electronic components are assembled incorrectly and the wire harness to be tested is unqualified. If they correspond, the parameter information detection function of the electronic components is started after the operation button 4 is pressed. Optionally, the wire harness detection device for the car roof can also include a display screen 5 and an alarm. The alarm can include a three-color light 6 and a buzzer (not shown in the figure). The three-color light 6 can emit three colors of light to form a prominent warning effect. If the parameter information of the electronic components is not within the qualified range of the parameters of the electronic components, the three-color light 6 and the buzzer give an alarm, and "NG" is displayed on the display screen 5 as an abnormal reminder and the abnormal position is displayed on the display screen 5. The device needs to be reset by pressing the operation button 4.Normally, the three-color lamp 6 and the buzzer alarm for 2 seconds, and the display screen 5 shows "OK" as a normal reminder. The qualified range of the parameters of the electronic components can be determined according to the model of the electronic components. The qualified range of the parameters of the electronic components should be input into the controller of the automotive ceiling wire harness detection device before detection. If the measured parameter information of the electronic components is within the qualified range of the parameters of the electronic components, it indicates that the electronic components can work normally and the electronic components are qualified. It should be noted that the alarm can not only alarm during the verification process of the parameter information of the electronic components, but also alarm according to actual needs during the process of verifying whether the actual electronic components in the wire harness to be tested are consistent with the electronic component identity information, or during the process of verifying whether the electronic component identity information and the wire harness assembly identity information correspond to each other. The automotive ceiling wire harness detection device in the embodiment of the present invention detects the electronic components through the wire harness bus, and realizes the quality detection of the wire harness, the electronic components and the whole after connection at the same time. The characteristic information of the electronic components is obtained through the detection instrument 2, and at the same time, the wire harness assembly identity information of the wire harness to be tested and the electronic component identity information of the electronic components in the wire harness to be tested are obtained through the identity identifier 1. By verifying the characteristic information of the electronic components and the electronic component identity information, it can be determined whether the actual electronic components in the wire harness to be tested are consistent with the electronic component identity information, and then by verifying the wire harness assembly identity information and the electronic component identity information, it can be determined whether the electronic components in the wire harness to be tested are consistent with the required electronic components of the wire harness, so as to verify the correctness of the wire harness assembly. Under the control of the controller, the parameter information of each electronic component is obtained simultaneously through at least two detection instruments 2. The detection instruments 2 are integrated together, and multi-channel synchronous detection is realized through the device, so that the parameters can be obtained quickly and efficiently. The parameter information of the electronic components is compared and verified with the qualified range of the parameters of the electronic components, so as to determine whether the wire harness to be tested is qualified. Therefore, the wire harness detection by the above method greatly improves the detection accuracy and detection efficiency.

[0038] Optionally, it further includes a wire harness connector 3. The wire harness connector 3 is used to connect the plug of the wire harness to be tested, and the detection instrument 2 is connected to the wire harness connector 3.

The device can also be provided with a wire harness connector interface for inserting the wire harness connector 3 into the wire harness connector interface for self-checking of the device before testing to ensure that all parts of the device work normally.

[0040] Furthermore, the wire harness connector 3 can include a pneumatic locking wire harness connector, and the pneumatic locking wire harness connector is used to automatically lock after connecting the plug of the wire harness to be tested.

[0041] The pneumatic locking wire harness connector can automatically lock the connection between the wire harness to be tested and the automotive roof wire harness detection device after connection, improving the reliability of the connection during the detection process. The pneumatic locking wire harness connector can be any wire harness connector with a pneumatic locking structure, and the present invention does not limit the specific structure of the pneumatic locking wire harness connector.

[0042] Optionally, it further includes a memory interface for accessing an external memory. The controller is further configured to store the detection results of each electronic component in the external memory after determining whether the wire harness to be tested is qualified.

[0043] Among them, the external memory can be inserted into the memory interface so that after the detection of the wire harness to be tested is completed, the detection results can be saved in the external memory, facilitating subsequent quality traceability of the wire harness to be tested. Exemplarily, the memory interface can be a USB interface, and the external memory can be a USB flash drive. Such a setting of the memory interface results in a high compatibility of the memory interface.

[0044] Optionally, it further includes a frame 7 and universal wheels 8. The frame 7 houses the controller, the identity recognizer 1, and the detection instrument 2, and the universal wheels 8 are provided between the frame 7 and the supporting surface.

[0045] Among them, components such as the controller, the identity recognizer 1, and the detection instrument 2 of various automotive roof wire harness detection devices can be arranged inside the frame 7, thereby improving the integration degree of the device. It can also include a front panel with a window. Inside the window, there are a display screen 5, operation buttons 4, and the detection instrument 2. At the bottom of the frame 7, there are also universal wheels 8. The device contacts the ground of the supporting device through the universal wheels 8, and the device can be moved flexibly and conveniently.

[0053] Among them, after connecting the wire harness to be tested, the range of characteristic parameters that the electronic component should have can be confirmed through the electronic component identity information. By comparing the measured characteristic information of the electronic component with the range of characteristic parameters that the electronic component should have, it is possible to verify whether the actual electronic component in the wire harness to be tested is consistent with the electronic component identity information. If they are not consistent, it indicates that the electronic component is incorrectly assembled and the wire harness to be tested is unqualified. If they are consistent, it is further verified whether the electronic component identity information corresponds to the wire harness assembly identity information. If they do not correspond, it indicates that the electronic component is incorrectly assembled and the wire harness to be tested is unqualified. If they correspond, after pressing the operation button 4, the parameter information detection function of the electronic component is started. Optionally, the automotive ceiling wire harness detection device may further include a display screen 5 and an alarm. The alarm may include a three-color light 6 and a buzzer. If the parameter information of the electronic component is not within the qualified range of the parameters of the electronic component, the three-color light 6 and the buzzer give an alarm, and "NG" is displayed on the display screen 5 as an abnormal reminder and the abnormal position is displayed on the display screen 5. The device needs to be reset by pressing the operation button 4. Normally, the three-color light 6 and the buzzer give an alarm for 2 seconds, and "OK" is displayed on the display screen 5 as a normal reminder. The qualified range of the parameters of the electronic component can be determined according to the model of the electronic component. The qualified range of the parameters of the electronic component should be input into the controller of the automotive ceiling wire harness detection device before detection. If the measured parameter information of the electronic component is within the qualified range of the parameters of the electronic component, it indicates that the electronic component can work normally and the electronic component is qualified. It should be noted that the alarm can not only give an alarm during the verification process of the parameter information of the electronic component, but also give an alarm according to actual needs during the process of verifying whether the actual electronic component in the wire harness to be tested is consistent with the electronic component identity information, or during the process of verifying whether the electronic component identity information corresponds to the wire harness assembly identity information. The automotive ceiling wire harness detection device in the embodiment of the present invention detects the electronic component through the wire harness bus, and realizes the quality detection of the wire harness, the electronic component and the whole after connection at the same time. The characteristic information of the electronic component is obtained through the detection instrument 2, and at the same time, the wire harness assembly identity information of the wire harness to be tested and the electronic component identity information of the electronic component in the wire harness to be tested are obtained through the identity recognizer 1.

Then, by verifying the wire harness assembly identity information and the electronic component identity information, it is determined whether the electronic component in the wire harness to be tested is consistent with the electronic component required by the wire harness, so as to verify the correctness of the wire harness assembly. Under the control of the controller, the parameter information of each electronic component is obtained simultaneously through at least two detection instruments 2. The detection instruments 2 are integrated together, and multi-channel synchronous detection is realized through the device, so that the parameters can be obtained quickly and efficiently.
