Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Fig. 1 is a schematic structural diagram of a power module testing system according to an embodiment of the present invention, and as shown in fig. 1, the system includes: the device comprises a starting device 10, a test starting device 20, a controller 30, a multi-path voltage display device 40 and a memory 50.
The starting device 10 is used for starting the power module testing system after the power supply is switched on according to the first operation instruction, and the power supply is also used for supplying power to the tested power module;
the test starting device 20 is used for generating a test trigger signal according to the second operation instruction;
the controller 30 is configured to, when a test trigger signal is detected, read a preconfigured channel output instruction from the memory 50 according to the test trigger signal, and send the channel output instruction to the power supply module to be tested, where the channel output instruction is used to instruct the power supply module to be tested to open all voltage output channels;
each of the multiple voltage display devices 40 (only 4 are exemplarily shown in fig. 1) is configured to display the voltage output from the voltage output channel electrically connected thereto for displaying to the operator, so that the operator can determine whether the power module under test is working normally.
Specifically, the power supply supplies power to each component in the power module test system and the tested power module after the startup starting device is closed. After detecting the second operation instruction, the test starting device 20 generates a test trigger signal and transmits the test trigger signal to the controller 30. In a specific example, both the power-on enabling means and the test enabling means 20 may be a switch. Referring to fig. 2, a schematic diagram of a circuit structure of a power module testing system is shown. After receiving the test trigger signal, the controller 30 reads a pre-configured channel output command from the memory 50 (e.g., the flash memory of fig. 2) and transmits the pre-configured channel output command to the power module under test. When the tested power supply module receives the channel output instruction, all the voltage output channels of the tested power supply module are opened to output voltage. Each voltage output channel is electrically connected to a voltage display device 40 (e.g. the voltmeter in fig. 2), and the voltage display device 40 is used for the voltage output by the voltage output channel electrically connected to it. And the output voltage is displayed to the working personnel, and the working personnel can judge whether the tested power supply module works normally according to the output voltage.
Specifically, during normal operation, the voltage output by each voltage output channel of the tested power supply module should be within a certain range, and if the voltage output by a certain current voltage output channel is not within a preset range, it indicates that the tested power supply module has a fault, i.e., works abnormally, and needs to be repaired.
Optionally, in order to facilitate the staff to check the normal working range of the output voltage of each voltage output channel, that is, the preset range, the system further includes a display panel 60, and the multiple voltage display devices 40 are all installed on the display panel 60. And displays the operating range of the output voltage of the corresponding voltage output channel in the vicinity of the mounting position of each voltage display device 40 on the display panel 60. The operating range of the output channel output voltage is displayed, for example, on the lower side or the left side of the installation position of the voltage display device 40. The specific setting is according to the actual conditions, and not too much description here. Fig. 3 is a schematic diagram of a display panel of a power module testing system. Fig. 4 is a side view of the power module testing system structure, and fig. 4 shows that there is a tilted panel tilted 45 ° to the horizontal, which is a display panel 60, and particularly, the object indicated by reference numeral 4 in fig. 4 is the display panel 60. As can be seen from fig. 3, the voltage meter corresponding to each voltage output channel in the power module under test is installed on the display panel 60 for displaying the output voltage. For example, fig. 3 shows a schematic diagram of a display panel of a 24-channel digital voltmeter. The corresponding position of the display panel 60 is designed with a silk screen for displaying the normal working range of the voltage output from the voltage output channel, so that the worker can conveniently determine whether the tested power module is in the normal working state according to the voltage range output from the voltage output channel of each voltage display device 40 in the multiple voltage display devices 40 and the currently output voltage. In fig. 3, the screen printing values are located on the left side, or the upper side, of the voltmeter mounting position, respectively. The left-hand recess of fig. 3 is used for mounting the power module under test. Referring to the position of reference numeral 1 in fig. 3, reference numeral 1 is used to indicate the power module interface 70 to be tested, reference numeral 2 is used to indicate the test starting device 20, and reference numeral 3 is used to indicate the power-on starting device 10. Reference numeral 4 is used for indicating a display panel, reference numeral 5 is used for indicating a voltmeter, and reference numeral 6 is used for indicating standard value silk screen printing.
Optionally, the system further comprises a power module interface 70 to be tested, as shown in fig. 1 in particular. The tested power supply module is electrically connected with each voltage display device 40 in the multiple voltage display devices 40 through the tested power supply module interface 70.
Alternatively, it is considered that the power supply used by us at ordinary times is 220v of alternating current power supply. The voltage required by the power module under test and the functional components in the power module testing system may be a dc power supply and the voltage is much less than 220V, so the system may further include the first voltage conversion circuit 80. The first voltage conversion circuit 80 is electrically connected to the power supply and the power module under test, respectively, and is configured to convert the voltage provided by the power supply into a voltage that is suitable for being directly used by the power module under test. In a specific example, the first voltage conversion circuit is a conversion circuit that converts an alternating voltage into a direct voltage.
For example, in fig. 2, the voltage required by the power module under test is DC 48V, so the first voltage conversion circuit 80 is an AC/DC voltage converter converting 220V to 48V, and the converted voltage is directly input to the power module under test.
Optionally, the power module under test is electrically connected to the first voltage conversion circuit 80 through the power module under test interface 70. For receiving the voltage converted by the first voltage conversion circuit 80.
Further alternatively, considering that the voltage required by the controller 30 may be lower than 48V, for example, the voltage required by the controller 30 is 3.3V. Therefore, the system may further include a second voltage conversion circuit 90 for converting a voltage conforming to the direct use of the power module under test into a voltage conforming to the direct use of the controller 30; or alternatively, for converting the voltage provided by the power supply to a voltage that is compatible for direct use by the controller 30.
In fig. 2, the second voltage converting circuit 90 is a DC/DC voltage converter, which is located between the first voltage converting circuit 80 and the controller 30, and converts the voltage converted by the first voltage converting circuit 80 into 3.3V for the controller 30 to use. In addition, since the controller 30 directly detects the test trigger signal generated by the test enabling device 20 and reads the preconfigured channel output instruction from the memory 50 after detecting the test trigger signal, the controller 30 is electrically connected to the test enabling device 20 and the memory 50, respectively, as shown in fig. 1 or fig. 2.
Optionally, the system may further include an interface conversion circuit 100, configured to transmit a channel output command issued by the controller 30 to the power module under test after the electrical connection between the controller 30 and the power module under test is established, as shown in fig. 1 or fig. 2. It should be noted that, because fig. 2 is a specific application example, the components in fig. 2 are not written with corresponding component numbers, and only specific components are taken as an example for description. However, the circuit principle used is the same as that of fig. 1, and will not be described more here.
In a specific example of an application, see in particular fig. 3. The left side of the power module testing system is an interface (see the position marked with the number 1 in fig. 3) between the power module to be tested and the power module testing system, and the power module to be tested is placed on the interface of the power module testing system. Firstly, a tester presses a starting switch (the position marked as 3 in fig. 3), 220V voltage of a 220V external power supply is converted into 48V voltage through an AC-to-DC conversion module, a power supply module testing system and a tested power supply module work, and the 48V voltage is converted into 3.3V voltage through a DC module to be supplied to a controller to work. And after the set-up key is pressed down, the tested power supply module and the power supply module testing system enter a working state.
Secondly, when the tester presses down a test switch (see the position marked as 2 in fig. 3) of the power module test system, when the controller detects that the test switch is closed, the controller can read channel output instructions stored in the flash and send the channel output instructions to the tested power module through the interface conversion circuit, the tested power module can open all voltage output channels after receiving the instructions, at the moment, a plurality of digital voltmeters (such as the voltmeters shown in the position marked as 5 in fig. 3) connected on the power module test system can display output voltage values of channels corresponding to the digital voltmeters in real time, the tester observes the head numerical values of the voltmeters and the standard value silk screen on the display panel, the tester presses down a switch key after the measurement is completed, the tested power module is taken down, then the next tested power module is changed to press down the switch key, and then the test key is pressed down to continue the test.
In the above specific example, the tested power module adopts a CAN differential bus communication mode, the controller CAN only recognize the TTL level, and in order to enable the controller and the power module to communicate normally, an interface conversion circuit that converts TTL to CAN is added between the controller and the tested module to implement protocol and level conversion. Of course, the interface conversion circuit may be other circuits, which are set according to actual conditions, such as signal conditions recognized by the power supply module under test and the controller, respectively, and will not be further described here.

Therefore, the tested power supply module outputs voltage through the voltage output channel and displays the voltage on the voltage display device. The staff can also judge whether the power module to be tested works normally according to the voltage output by each voltage output channel displayed on the voltage display device. Through this kind of mode, the staff no longer need test in proper order by the condition of each way voltage output channel of test power module, realizes that a key opens all output channels, shows all output channel's voltage measured value simultaneously, makes things convenient for the staff directly to judge whether voltage module is normal, and then improves production efficiency, reduces the omission factor, greatly reduced cost of labor moreover.
