In some embodiments, the TYPE-C powered-on port is monitored, specifically whether a USB TYPE-C docking station is inserted into the TYPE-C powered-on port is monitored, and if the USB TYPE-C docking station is monitored to be inserted into the TYPE-C powered-on port, a first request is sent to the USB TYPE-C docking station, wherein the first request is used for acquiring current and voltage from the USB TYPE-C docking station.
S103: the current and voltage fed back by the USB TYPE-C docking station for the first request are received so as to switch on the preset load.
Based on the above example, when the USB TYPE-C docking station receives the first request, current and voltage are input to the TYPE-C power receiving port, the TYPE-C power receiving port is connected to the load, and when the TYPE-C power receiving port is input with current and voltage by the USB TYPE-C docking station, the TYPE-C power receiving port is connected to the load, and the load is in an energized state.
S104: and detecting whether the voltage and the current corresponding to the load belong to a preset interval, and if so, executing S105.
The preset interval is set based on requirements.
It can be understood that when the load is turned on, the load has current and voltage passing through, the current and voltage of the load are detected, and whether the voltage and the current belong to a preset interval is determined.
Specifically, the preset interval includes a voltage interval and a current interval, and then it is specifically detected whether the voltage corresponding to the load belongs to the voltage interval, and whether the current corresponding to the load belongs to the current interval.

In the embodiment of the disclosure, the switching unit is controlled to switch the front side and the back side of the TYPE-C power supply port, so that manual operation is not needed, the problem of low testing efficiency in the prior art is avoided, the testing time and the cost are saved, and the technical effect of testing accuracy is improved.
In some embodiments, if the voltage and current corresponding to the load do not belong to the preset interval, the step of sending the first request for acquiring the voltage and current to the USB TYPE-C docking station may be returned, i.e. the voltage and current are re-requested, so as to re-detect the voltage and voltage corresponding to the load, and so on.
Of course, in other embodiments, since the voltage and the current may have a certain deviation due to an unstable condition when the circuit is just connected, if the voltage and the current corresponding to the load do not belong to the preset interval, the voltage and the current corresponding to the load may be re-acquired, and whether the re-acquired voltage and current belong to the preset interval may be re-detected.

and the switching unit 26 is connected with the TYPE-C power supply port 22 and is used for switching the front side and the back side of the TYPE-C power supply port 22.
The voltage output by the power supply 23 can be regulated by the singlechip 21, and the voltage is 5V-20V. Similarly, the singlechip 21 can also regulate the current output by the power supply 23, and can interrupt the power supply of the power supply 23 when an overcurrent condition occurs.
As can be seen in conjunction with fig. 7, in some embodiments, the test plate further comprises: a switching unit 27 and a TYPE-C signal interface 28 respectively connected with the singlechip 21, wherein,
the switching unit 27 is further connected to the TYPE-C power receiving port 24 and the TYPE-C signal interface 28, respectively, and is configured to switch the TYPE-C power receiving port 24 connected to the singlechip 21 to the TYPE-C signal interface 28; alternatively, the TYPE-C signal interface 28 connected to the singlechip 21 is switched to the TYPE-C power receiving port 24.

The external device includes, but is not limited to, a notebook computer as described in fig. 1.
Of course, in some embodiments, the video image may also be detected by the image capture card. Because the detection efficiency of the video image of the external equipment is higher, the video image is conveniently sent to the external equipment by the image acquisition card, the video image is detected by the external equipment, and the detection result is output.
The test of the USB TYPE-C docking station is realized based on the established communication connection, and the communication is realized by a CC line, and in general, the CC line has two wires, namely CC1 and CC2, or is called CC and VCONN. After the front and back sides are identified, they are called CC and VCONN, and before the front and back sides are identified, they are called CC1 and CC2.
The principles of the switching unit and the switching unit are now described with reference to fig. 8 (fig. 8 is a schematic diagram of an embodiment of the present disclosure), as follows:
A switching unit (also referred to as a CC switching unit), wherein the CC line includes two branches, and one branch is used for switching the CC1 connected to the CC line to the CC2 (for example, the CC2 is connected to the TYPE-C power supply port); or exchanging the CC2 connected to the CC circuit for CC1 (such as connecting with the TYPE-C power supply port by the CC 1), and connecting the other branch of the VCONN with the singlechip or connecting the CC to the singlechip.
Wherein, CC1 at both ends of TYPE-C is directly communicated, and similarly, CC2 at both ends is also directly communicated, and VCONN is communicated.
The switching unit (also called as CC switching unit) is used for switching the TYPE-C power receiving port connected to the singlechip into a TYPE-C signal interface; or switching the TYPE-C signal interface connected to the singlechip into a TYPE-C power receiving port. Because the TYPE-C power receiving port is connected with the plug of the USB TYPE-C docking station, when the TYPE-C power receiving port is connected to the singlechip by the switching unit, the singlechip needs to identify the front and back sides of the insertion of the USB TYPE-C docking station, and separate out each signal in the USB TYPE-C docking station according to the identified result, so that the operations such as signal amplification and test are facilitated.
In some embodiments, the definition of pins of a TYPE-C socket may be found in Table 1,
table 1:
wherein, the definition of each pin of the TYPE-C plug can be seen in Table 2,
Table 2:
wherein, the relevant definition of the wires of the plugs of TYPE-C can be seen in table 3:
table 3:
as can be seen from table 3, in the embodiment of the present disclosure, VCONN (B5 pin) at two ends of the plug of TYPE-C is also directly connected, so the switching unit may be responsible for the switching between CC1 and CC2, i.e. CC1 is connected to CC, and CC2 is connected to VCONN; alternatively, CC2 is connected to CC and CC1 is connected to VCONN.
In some embodiments, the socket of the USB TYPE-C docking station has no data transfer function, and therefore, there is no need to test USB 2.0, USB 3.0, and DP data transfers.
In some embodiments, the singlechip may be a singlechip that supports CC communications for two TYPE-C, such as STM32G071; or two external CC controllers and a singlechip.
