Example two

The embodiment provides a power line testing method, which can be applied to the power line testing equipment, so that the power line testing equipment can effectively test a power line.

As shown in fig. 9, the power line testing method includes the following steps:

and S1, receiving a test starting instruction.

Wherein the start test command may be input into the power line test apparatus by an operator. For example, an operator may press a start button on the power cord testing device to trigger the power cord testing device to power on and begin testing the power cords connected thereto. Alternatively, the power line testing device may be connected to a terminal (e.g., a computer), and an operator may click on the terminal to initiate a procedure to turn on the power line testing device, so that the power line testing device tests the power line.

Alternatively, before step S1, the operator may insert one end of the power cord into the first socket 11 of the power cord testing device and the other end of the power cord into the second socket 12 of the power cord testing device to complete the preparation work.

It should be noted that step S1 may be executed by a receiving module in the electronic device in the testing machine 1, that is, the receiving module in the first embodiment is used to receive the test starting instruction. And the receiving module can send the received test starting instruction to a control module in the electronic device so that the control module can process the test starting instruction.

And S2, controlling a fixing device in the power line testing equipment to fix the end of the power line according to the received test starting instruction.

The end of the power line is a part of one end of the power line, which is not inserted into the first socket 11, and/or the end of the power line is a part of the other end of the power line, which is not inserted into the second socket 12, and the fixing device fixes the end of the power line, so that the two ends of the power line can be stably inserted into the testing machine 1, and the power line is prevented from falling off from the testing machine 1 due to the gravity of the power line.

It should be noted that step S2 may be executed by a control module in the electronic device, that is, the control module is configured to control the fixing device to fix the end of the power line according to the received test starting command.

S3, detecting whether the power line is bad, if not, executing step S4, if yes, executing step S5.

The detection result of the power line can be divided into a qualified condition and a non-qualified condition, and the two conditions are determined by a detection module in the electronic device. The detection module can detect the electrical performance condition of the power line, if the power line is detected to be electrically poor, when the power line is detected to be electrically poor, the detection result of the power line can be determined to be unqualified, and the detection module sends a signal of the power line which is unqualified to the second sending module of the electronic device; when the power line is detected to have no electrical defect, the detection result of the power line can be determined to be qualified.

S4, determining the power line is qualified, and sending a second detection result signal for displaying the qualification.

When the power line is determined to be a qualified power line, the sending module may send a second detection result signal to the printing device and the display 13 in the testing machine 1, so that the printing device can mark the head or the tail of the power line, for example, print a "T" or a "check mark" on the head or the tail of the power line to identify the power line as a qualified power line. And the display screen 13 can display the qualified identification, so that the operator can conveniently determine the detection result of the power line. Meanwhile, the sending module can also feed back a message that the power line is a qualified power line to the control module, so that the control module controls the fixing device to loosen the end part of the power line according to the message, and further an operator can pull out the qualified power line from the testing machine 1.

Alternatively, when the power line is qualified, the second detection result signal may be a reminder in various forms, such as a green indicator light, to notify the operator.

It should be noted that, after the step S4 is completed, it indicates that the power line is a qualified power line, and at this time, the flow ends without continuing to perform the step S5.

S5, determining the power line is not qualified, and sending a first detection result signal for displaying that the power line is not qualified.

When the power line is a qualified power line, the sending module may send a first detection result signal indicating that the power line is a qualified power line to the printing device and the display 13 in the testing machine 1, so that the printing device can mark the head or the tail of the power line, for example, print "R" or "x" on the head or the tail of the power line to identify that the power line is an unqualified power line. And the display screen 13 displays the qualified identification, so that the operator can conveniently determine the detection result of the power line.

Alternatively, when the power line is an unqualified power line, the first detection result signal may be a reminder in various forms, such as a red indicator light is turned on or an alarm is sounded to inform an operator.

After the execution of step S5 is completed, the flow is not completed, and step S6 needs to be continued.

And S6, sending a cutting signal to a cutting device in the power line test equipment according to the first detection result signal.

Alternatively, when the power line is detected as a defective power line, it is necessary to generate a cut-off signal according to the first detection result signal and send the cut-off signal to the cutting device.

S7, the cutting device cuts off the power line according to the cutting signal.

Wherein, the cutting device 2 can cut off the unqualified power line according to the cutting signal so as to prevent the unqualified power line from mixing into the qualified power line.

In the power line testing method provided by the embodiment, when the power line is detected to be an unqualified power line, the power line does not need to be taken down from the testing machine 1, but the power line inserted into the testing machine 1 is directly controlled to be cut off on the testing machine 1, so that the disconnected unqualified power line is difficult to be confused with a qualified power line, the power line can be effectively detected, the unqualified power line is prevented from being mixed into the qualified power line, the unqualified power line is prevented from flowing into the market, and potential safety hazards are eliminated.

Further, referring to fig. 10, the step S3 includes:

s31, judging whether the power line is short-circuited, if yes, executing step S4, and if not, executing step S32.

Alternatively, the detection module may include one or more detection circuits, and when two ends of the power line are plugged into the first jack 11 and the second jack 12, a loop can be formed with the detection circuits, and signals such as current and voltage of the detection circuits are monitored by components arranged in the detection circuits to determine whether the power line is short-circuited. When the judgment result is that the power line has a short circuit, the power line can be directly determined to be unqualified, and when the judgment result is that the power line does not have a short circuit, other parameters of the power line need to be judged.

S32, judging whether the power line has voltage resistance, if not, executing step S5, if yes, executing step S33.

Further, step S32 may include:

s321, testing whether the copper wire of the power line leaks outwards, if so, executing step S5, and if not, executing step S322.

S322, testing whether the copper wire of the power line is broken, if so, executing a step S5, otherwise, executing a step S33.

Wherein, the withstand voltage condition of test power cord can be confirmed from two aspects of interior high voltage test and outer high voltage test: when the power line has an external high voltage condition, the power line is indicated to cause the defects of external leakage of a copper wire and the like in the riveting process, and further the power line possibly has a leakage risk; when the power line has internal high voltage, the power line has defects of broken copper wires and the like in the core stripping process, and further the high voltage defect of the power line can be caused. In the case of any of the above cases, the power supply line is not resistant to voltage, and the power supply line is a defective power supply line.

Optionally, when the judgment result is that the power line is not voltage-resistant, determining that the power line is an unqualified power line, and no further detection of other parameters of the power line is needed; and when the judgment result is that the power line is voltage-resistant, determining that the power line is qualified, and further judging other parameters of the power line.

S33, testing the grounding function value of the power line, and determining whether the grounding performance of the power line reaches the standard according to the grounding function value, if not, executing a step S5, and if so, executing a step S34.

When the judgment result shows that the grounding performance of the power line does not meet the standard, determining that the power line is an unqualified power line, and no further detection of other parameters of the power line is needed; and when the judgment result is that the grounding performance of the power line meets the standard, determining that the power line is a qualified power line, and further judging other parameters of the power line.

and S331, testing the grounding function value of the power line.

And S332, acquiring the grounding function value range of the power line.
