[0002] In the prior art, to test the continuity of a circuit, it is usually necessary to use the master and slave test leads of a tester to touch the ends of the circuit under test to determine its continuity. This testing method requires that both ends of the circuit under test be exposed during use. If one end of the circuit under test is closed and cannot be contacted by the test leads, the test process cannot be carried out. The corresponding structure must be removed to expose the end of the circuit, which increases the complexity of the test operation.

[0009] Furthermore, the electromagnetic signal is a square wave signal.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] It should be understood that when an element (such as a layer, film, region, or substrate) is described as being "on" another element, the element may be directly on the other element or intervening elements may be present. Moreover, in the specification and claims, when it is described that an element is "connected to" another element, the element may be "directly connected to" the other element or "connected to" the other element through a third element.

[0026] Figure 1 is a line status testing method according to an embodiment of the present invention, such as Figure 1 As shown, the method includes the following steps:

[0027] Step S102: Figure 2 The area where the target line 10 is shown emits an electromagnetic signal;

[0028] Step S104, determining whether the target line 10 outputs a voltage signal, where the voltage signal is generated by the target line 10 based on induction of the electromagnetic signal;

[0029] Step S106, when the target circuit 10 outputs a voltage signal, determining that the target circuit 10 is turned on;

[0030] Step S108 : When the target circuit 10 does not output a voltage signal, it is determined that the target circuit 10 is not conducting.

[0031] The line status testing method using the above scheme includes: transmitting an electromagnetic signal to the area where the target line 10 is located; determining whether the target line 10 outputs a voltage signal, the voltage signal being generated by the target line 10 based on induction of the electromagnetic signal; if the target line 10 outputs the voltage signal, determining that the target line 10 is conductive; if the target line 10 does not output the voltage signal, determining that the target line 10 is not conductive. When testing the status of the target line 10, by transmitting the electromagnetic signal to the target line 10, the target line 10 generates a voltage signal due to electromagnetic induction. If the target line 10 outputs the voltage signal, it indicates that the target line 10 is conductive and not broken. If the target line 10 does not output the voltage signal, it indicates that the target line 10 is not conductive, i.e., it has a broken circuit. Using this testing method, only one end of the target line 10 needs to be exposed for wiring, without requiring both ends of the target line 10 to be exposed. This makes it easy to test the continuity and disconnection status of a circuit with one end closed, solving the problem of inconvenient operation when conducting continuity and disconnection tests on circuits with one end closed in the prior art.

[0032] It is understood that the generation of the voltage signal depends on changes in the magnetic field surrounding the target line 10. By controlling the emission of a changing electromagnetic signal to the target line 10, the voltage signal can be continuously generated in the target line 10. Of course, since the electric field also changes from zero to a point at the moment the electromagnetic signal is emitted, the electromagnetic signal does not necessarily need to be changing.

[0033] Specifically, the target line 10 is one of multiple lines to be tested, and the multiple lines to be tested are connected to multiple first interfaces of the connector in a one-to-one correspondence. The connector includes multiple second interfaces, and the multiple second interfaces are connected to the multiple first interfaces in a one-to-one correspondence. Determining whether the target line 10 outputs a voltage signal includes: determining whether the target interface outputs a voltage signal, the target interface is one of the multiple second interfaces, and the first interface corresponding to the target interface is used to connect to the target line 10; when the target interface outputs a voltage signal, determining that the target line 10 outputs a voltage signal; when the target interface does not output a voltage signal, determining that the target line 10 does not output a voltage signal.

[0034] That is, the multiple first interfaces of the connector are correspondingly connected to the multiple lines to be tested. When an electromagnetic signal is transmitted to the target line 10, if the corresponding second interface outputs a voltage signal, it means that the target line 10 is conductive.

[0035] Specifically, when the target line 10 does not generate a voltage signal, the line status testing method also includes: determining whether each second interface other than the target interface among multiple second interfaces outputs a voltage signal; when any second interface other than the target interface outputs a voltage signal, determining that there is a wiring error between the target line 10 and the connector.

[0036] If, when an electromagnetic signal is transmitted to the target line 10, the corresponding second interface does not output a voltage signal, but any other interface outputs a voltage signal, it indicates that there is a wiring error between the target line 10 and the connector, that is, the target line 10 is not connected to the corresponding first interface, which facilitates the inspection of the correctness of the line connection.

[0037] Specifically, the electromagnetic signal is a square wave signal. In this embodiment, the electromagnetic signal is set to a square wave signal, which can ensure that the target line 10 generates a periodically changing voltage signal, which is convenient for analysis.

[0038] According to a second aspect of an embodiment of the present invention, a line status testing device is provided, comprising: an electromagnetic signal transmitting component 1, the electromagnetic signal transmitting component 1 having a transmitting antenna for transmitting an electromagnetic signal, so as to transmit the electromagnetic signal to a target line 10 via the transmitting antenna; an electrical signal receiving component 2, the electrical signal receiving component 2 having a wiring port for communicating with the target line 10, so as to receive the voltage signal via the electrical signal receiving component 2 when the target line 10 outputs a voltage signal, the voltage signal being generated by the target line 10 based on electromagnetic signal induction; and a human-computer interaction component 3, the human-computer interaction component 3 being communicatively connected to the electrical signal receiving component 2, so as to receive and output a voltage signal reception result from the electrical signal receiving component 2.

[0039] When the line status test device with this structural arrangement is in use, the electromagnetic signal transmitting component 1 can transmit an electromagnetic signal to the target line 10. The target line 10 generates a voltage signal based on the induction of the electromagnetic signal. The wiring port of the electrical signal receiving component 2 is connected to the target line 10, thereby receiving the voltage signal. The human-computer interaction component 3 is connected to the electrical signal receiving component 2, and can receive and output the voltage signal reception result of the electrical signal receiving component 2. Accordingly, if the human-computer interaction component 3 shows that the electrical signal receiving component 2 has received the voltage signal, it means that the target line 10 is conductive; otherwise, it means that the target line 10 is not conductive. In this way, only one end of the target line 10 needs to be exposed for wiring, and both ends of the target line 10 do not need to be exposed. This can conveniently test the on / off status of a circuit with one end closed, solving the problem of inconvenient operation when performing on / off testing on a circuit with one end closed in the prior art.

[0040] Specifically, the human-computer interaction component 3 includes a signal processing element, which is used to: determine that the target line 10 is conductive when the electrical signal receiving component 2 receives a voltage signal; determine that the target line 10 is not conductive when the electrical signal receiving component 2 does not receive a voltage signal; the human-computer interaction component 3 is also used to output the conductive state result of the target line 10.

[0041] Specifically, the electromagnetic signal transmitting component 1 further includes a single-phase inverter circuit, which is connected to the transmitting antenna.

[0042] Specifically, the electromagnetic signal transmitting component 1 further includes a first filter circuit, an input end of the first filter circuit is connected to the output end of the single-phase inverter circuit, and an output end of the filter circuit is connected to the transmitting antenna.

[0043] The setting of the first filter circuit can filter out noise interference in the signal, which is beneficial to ensure the accuracy of the test. Preferably, the first filter circuit is an LC filter circuit, which can effectively remove the peak fluctuations generated by the single-phase inverter circuit and improve the accuracy of the overall detection of the system.

[0044] In addition, the electrical signal receiving component 2 includes at least one of the following: an amplifying circuit, a second filtering circuit, and an analog-to-digital conversion circuit.

[0045] The electrical signal receiving component 2 includes a wireless communication module, which communicates with the human-computer interaction component 3 and the test management platform via the wireless communication module. The electrical signal receiving component 2 can receive test task information from the test management platform via the wireless communication module and transmit the test management information to the human-computer interaction component 3 via the wireless communication module. This facilitates the operator's understanding of the test task and comparison with the test results, thereby facilitating the analysis of faults such as line breaks and wiring errors.

Moreover, the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system, such as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be performed in a different order than shown here.

The aforementioned integrated units may be implemented in the form of hardware or software functional units.
