[0003] In related technologies, battery clamps are used to hold the battery, and then a band switch is manually turned to switch the clamp's actions. However, manually turning the band switch can cause the battery clamp to move, affecting the testing process and results. Therefore, how to avoid the clamp from moving has become an urgent problem to be solved. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0022] This application discloses a photovoltaic cell test fixture switcher. (Refer to...) Figure 1 A photovoltaic cell test fixture switcher includes a control module 1, a transmission module, a switching module 3, and a signal input interface 4. The control module 1 is connected to the transmission interface 2, which is used to connect to a host computer. The control module 1 is also connected to the control terminal of the switching module 3. The input terminal of the switching module 3 is connected to the signal input interface 4, which is used to receive the signal to be tested. The output terminal of the switching module 3 is connected to an output interface 5.
[0023] The host computer sends a command, and after receiving the command, the control module 1 outputs a control signal to control the switching module 3 to switch, thereby causing the signal to be tested to be output from the output interface 5 through the path switched by the switching module 3. By controlling the switching module 3 to switch, different paths are generated, so that the output interface 5 outputs different signals to be tested. That is, it can be controlled by the host computer to automatically switch so that the output interface 5 outputs the required signal. Compared with the manual operation of the band switch in related technologies, it can improve convenience and also avoid the movement of the clamp position caused by manual operation of the switch, which would affect the battery test.
[0024] Among them, the control module 1 can be an STC15F2K60S2 microcontroller, the switching module 3 can be a ZDQH-16-2 relay board, and the transmission interface 2 can be an RS323 interface.
[0025] Reference Figure 2 Specifically, the output interface 5 includes a first output interface 51 and a second output interface 52, and the signal input interface 4 includes a first signal input interface 41 and a second input interface. The ground pin of the first output interface 51 is connected to the signal common pin of the first signal input interface 41, and the ground pin of the second output interface 52 is connected to the signal common pin of the second signal input interface 42.
[0026] The interconnection between the pins is used to directly transmit specific signals to be tested.
[0027] A signal isolation module 6 is also provided between the control module 1 and the transmission interface 2. The signal isolation module 6 is connected to the control module 1 and the transmission interface 2 respectively to achieve electrical isolation and play a protective role.
[0028] Reference Figure 1 and Figure 3 A photovoltaic cell test fixture switcher also includes a power module 7, to which both the control module 1 and the switching module 3 are connected. The power module 7 includes a power interface M, a conversion submodule U, a protection submodule F, and an indicator submodule. The power interface M is connected to the conversion submodule U and is used to connect to an external power source. The protection submodule F and the indicator submodule are both located between the power interface M and the conversion submodule U. The conversion submodule U is connected to the control module 1 and the switching module 3. After the power interface M connects to an external power source, it receives power. Then, the conversion submodule U converts the externally supplied power, thereby converting AC to DC output. Simultaneously, it performs voltage reduction to ensure the output voltage meets the voltage requirements of the control module 1 and the switching module 3. The protection submodule F can disconnect when abnormal circuit current occurs, thus protecting the circuit.
[0029] The conversion submodule U can be a converter of model JMD10-5.
[0030] The indicator submodule includes a switch K and an indicator light P. The specific connections between the switch K and the indicator light P are as follows: Figure 3 Show.
[0031] The implementation principle of a photovoltaic cell test fixture switcher according to an embodiment of this application is as follows: After connecting the power module 7 to an external power source and closing the switch, the power module 7 can supply power to the control module 1 and the switching module 3. Then, the operator sends control commands through the host computer. The control commands are transmitted to the control module 1. The control module 1 converts the control commands and outputs control signals to the switching module 3. The switching module 3 performs corresponding actions according to the control signals to transmit the test signal at the signal input interface 4 to the output interface 5. That is, the control module 1 controls the action of the switching module 3 to switch different paths to achieve the transmission of the required test signal from the signal input interface 4 to the output interface 5.
[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
