The present disclosure does not limit the type of operating system of the electronic device. For example, an Android system, a Linux system, a Windows system, an iOS system, etc.
Based on the foregoing description, the embodiment of the present disclosure will take an electronic device as an example, and details a testing method for a multi-core cable provided by the present disclosure in combination with an application scenario.
As shown in fig. 1, the testing method of the multi-core cable includes:
and S10, the master device sends an initial test signal to the master port of the test sub-cable in the multi-core cable.
For example, the testing method of the multi-core cable provided by the embodiment of the disclosure may be applied to testing a cable laid on a railway, and the testing method of the multi-core cable may be applied to a testing apparatus of the multi-core cable, where the testing apparatus of the multi-core cable includes a master device and a slave device, and the multi-core cable includes a plurality of sub-cables. Illustratively, the multi-core cable includes 8 sub-cables or 12 sub-cables or 37 sub-cables. When one sub-cable in the multi-core cable is in a conducting state, in order to conveniently and quickly test the states of other sub-cables, one sub-cable in other non-test conducting states is selected as a test sub-cable, and at the moment, the main device is electrically connected with a main port of the test sub-cable and sends an initial test signal to the main port of the test sub-cable.
And S20, the master device sends an initial command signal to the slave device.
The initial instruction signal is used for instructing the slave device to connect the slave port of the test sub-cable with the slave port of a first target sub-cable, and the first target sub-cable is a sub-cable in a conducting state in the multi-core cable.
After the master device sends an initial test signal to the master port of the test sub-cable, the master device sends an initial command signal to the slave device, the initial command signal instructs the slave device to connect the slave port of the test sub-cable with the slave port of a first target sub-cable, and at this time, the first target sub-cable refers to a sub-cable in a conducting state in the multi-core cable.
S30, when the master device detects the initial electrical signal of the master port of the first target sub-cable, the master device sends a target command signal to the slave device and a target test signal to the master port of the test sub-cable.
Wherein the target instruction signal is used for instructing the slave device to connect the slave port of the first target sub-cable and the slave port of the second target sub-cable.
Because the first target sub-cable is in a conducting state, when the slave device connects the slave port of the test sub-cable with the slave port of the first target sub-cable according to the initial instruction signal sent by the master device, if the test sub-cable is in the conducting state, the master device sends an initial test signal to the master port of the test sub-cable, the initial test signal is sent to the slave port of the first target sub-cable through the slave port of the test sub-cable and returns to the master port of the first target sub-cable, and the master device detects an initial electrical signal returned by the master port of the first target sub-cable. If the test sub-cable is in a non-conducting state, at this time, the master device sends an initial test signal to the master port of the test sub-cable, and the initial test signal is not sent to the slave port of the first target sub-cable through the slave port of the test sub-cable, and the master device cannot detect an initial electric signal returned by the master port of the first target sub-cable.
After the main device detects an initial electric signal of a main port of a first target sub-cable, namely, after the test sub-cable is determined to be in a conducting state, the main device sends a target instruction signal to the slave device and sends a target test signal to the main port of the test sub-cable, the slave device connects a slave port of the first target sub-cable with a slave port of a second target sub-cable according to the target instruction, and then the main device detects a mixed state, a short-circuit state or an insulation state of the test sub-cable and the second target sub-cable according to the detected target electric signal of the main port of the first target sub-cable.
And S40, after detecting the target electric signal of the main port of the first target sub-cable, the main device determines the connection state of the test sub-cable according to the target electric signal.
The connection state comprises a mixed line state, a short circuit state and an insulation state.
Specifically, if the test sub-cable is mixed with the second target sub-cable, after the master device sends the first target command signal to the slave device, the master device detects a first target electrical signal at a master port of the first target sub-cable; if the test sub-cable is short-circuited with the second target sub-cable, after the master device sends a second target instruction signal to the slave device, the master device detects a second target electric signal at a master port of the first target sub-cable; if the test sub-cable is not insulated from the second target sub-cable, after the master device sends a third target command signal to the slave device, the master device detects a third target electrical signal at the master port of the first target sub-cable.
According to the testing method of the multi-core cable, the main equipment sends an initial testing signal to a main port of a testing sub-cable in the multi-core cable; the master device sends an initial instruction signal to the slave device, wherein the initial instruction signal is used for instructing the slave device to connect the slave port of the test sub-cable with the slave port of the first target sub-cable; when the master device detects an initial electric signal of a master port of a first target sub-cable, the master device sends a target instruction signal to the slave device and sends a target test signal to a master port of a test sub-cable, wherein the target instruction signal is used for instructing the slave device to connect a slave port of the first target sub-cable with a slave port of a second target sub-cable; after the main equipment detects a target electric signal of a main port of the first target sub-cable, the connection state of the test sub-cable is determined according to the target electric signal, wherein the connection state comprises a mixed wire state, a short circuit state and an insulation state, the mixed wire, the short circuit and the insulation of the sub-cable of the multi-core cable are detected, and the test precision and the test efficiency are improved.
Fig. 2 is a schematic flow chart of another testing method for a multi-core cable according to an embodiment of the present disclosure, where on the basis of the foregoing embodiment, as shown in fig. 2, step S30 further includes:
s210, the main equipment determines the test type of the test sub-cable.
When the main device detects an initial electric signal of the main port of the first target sub-cable, the main device can determine that the test sub-cable is in a conducting state at the moment, in order to avoid the problems of short circuit, mixed wire or non-insulation and the like between the test sub-cable and other sub-cables, before the main device sends a target test signal to the main port of the test sub-cable, the main device determines the test type of the test cable, and then sends the target test signal to the main port of the test sub-cable according to the determined test type.
Specifically, when the main device determines that the test type is a mixed state and a short-circuit state of the test sub-cable, the main device sends a first target test signal to a main port of the test sub-cable in the multi-core cable.
When the main equipment determines that the test type is the insulation state of the test sub-cable, the main equipment sends a second target test signal to a main port of the test sub-cable in the cable.
Specifically, the main device comprises a main controller, a 3V reference source, a 250V reference source and a relay, the main controller is connected with a main port of the test sub-cable through the relay, when the main device determines that the test type is a mixed state and a short-circuit state of the test sub-cable, at this time, the main controller outputs a control signal to control the relay to be switched on, the 3V reference source outputs a 3V voltage signal to the main port of the test sub-cable, when the main device determines that the test type is an insulation state of the test sub-cable, at this time, the main controller outputs a control signal to control the relay to be switched on, the 250V reference source outputs a 250V voltage signal to the main port of the test sub-cable, namely, 3V is a first target test signal, and 250V is a second target test signal.
According to the testing method of the multi-core cable, the main equipment sends a target testing signal to a main port of a testing sub-cable according to the determined testing type, and when the main equipment determines that the testing type is a mixed line state and a short circuit state of the testing sub-cable, the main equipment sends a first target testing signal to the main port of the testing sub-cable in the multi-core cable; when the main equipment determines that the test type is the insulation state of the test sub-cable, the main equipment sends a second target test signal to a main port of the test sub-cable in the cable, mixed line detection, short circuit detection and insulation detection of the test sub-cable are achieved, and test precision is improved.
Fig. 3 is a schematic flowchart of a testing method for a multi-core cable according to an embodiment of the present disclosure, where on the basis of the corresponding embodiment in fig. 2, as shown in fig. 3, an implementable manner of step S30 includes:
and S31, when the master device determines that the test type is the mixed state of the test sub-cable, the master device sends a first target instruction signal to the slave device, wherein the first target instruction signal is used for indicating that the slave device is to be connected with the slave port of the first target sub-cable and the slave port of the second target sub-cable in sequence.
The second target sub-cable is any one of the sub-cables except the first target sub-cable and the test sub-cable.
Illustratively, if the multi-core cable includes 12 sub-cables, the first target sub-cable is a first sub-cable in the multi-core cable, the test sub-cable is a second sub-cable in the multi-core cable, when the master device determines that the test type is the mixed state of the test sub-cable, the master device sends a first target command signal to the slave device, and the slave device connects the slave port of the first target sub-cable with the slave port of the second target sub-cable in sequence according to the first target command signal, at this time, the second target sub-cable is any one sub-cable except the first target sub-cable and the test sub-cable, that is, the slave device connects the slave port of the first sub-cable with the slave port of the third sub-cable in sequence according to the first target command signal, the slave port of the first sub-cable is connected with the slave port of the fourth sub-cable, the slave port of the first sub-cable is connected with the slave port of the fifth sub-cable, .., the slave port of the first sub-cable is connected with the slave port of the twelfth sub-cable, and then the connection state of the test sub-cable is determined according to the first target electric signal of the master port of the first target sub-cable detected by the master device.
Corresponding to step S31, one implementation manner of step 40 is:
and S41, when the main device detects the first target electric signal of the main port of the first target sub-cable, the state of the test sub-cable in the multi-core cable is in a mixed state.
