Description

Technical Field

[0001] This invention belongs to the field of testing technology, and in particular relates to a comprehensive testing system and method for power modules. Background Technology

[0002] A wide variety of power modules are used in railway signaling products. Based on voltage conversion type, there are AC220V to AC110V, AC220V to DC110V, AC220V to DC24V, AC220V to DC12V, DC24V to DC12V, DC24V to DC5V, DC12V to DC12V, and DC12V to DC5V. Based on module size, there are large modules for rack mounting (DIN rail or screw mounting) and smaller modules for circuit boards, which also come in various pin packages. During incoming power module inspection, electrical performance testing is required, i.e., applying input power according to the module's parameters and measuring whether the output voltage meets the requirements.

[0003] The current technology involves inspectors manually powering on power modules according to the inspection requirements, measuring and recording the output voltage, and then manually entering the data into the system. This is relatively simple for larger power modules; however, for power modules used on circuit boards, which are generally smaller, powering on them is inconvenient, and measuring the output voltage test points is also difficult, posing a risk of short-circuit damage. After measurement, the test results must be manually recorded and judged for pass / fail status, resulting in low testing efficiency and risks of operational and misjudgment errors.

[0004] Chinese patent CN107643496A discloses a power module testing device, including an insulating box, a circuit board, and studs. The circuit board is fixed inside the insulating box by the studs. Multiple probe sleeves, matching the contact positions of the power module, are fixed to the center of the circuit board. Hollow mounting pins are fixed to the upper ends of the probe sleeves, and detachable probes are fitted inside the mounting pins. The probes are inserted into the probe sleeves. The circuit board also has two three-state switches and a BNC connector. The three-state switches are electrically connected to the probe sleeve located at the input end of the power module, and the probe sleeve located at the output end of the power module is electrically connected to the BNC connector. Clamping components for restricting the movement of the power module are provided on both sides of the probe sleeves. The probes are detachably inserted into the probe sleeves. After multiple uses of the fixture, if the probe interfaces are damaged or have poor contact, the probes can be directly pulled out for recycling. However, this invention can only test a specific type of power supply and cannot test power supplies of different models and sizes. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a comprehensive testing system and method for power modules.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] This invention provides a comprehensive testing system for power modules, comprising: a host computer, a voltage acquisition module, a communication module, a power supply module, a switching control module, a power supply test socket, and a power supply under test. The power supply test socket includes a power mounting base, limiting posts, a cover plate, a cover plate spring-loaded post, a latch, and a handle. The power mounting base includes a groove, a probe through-hole, and a built-in fan. The groove corresponds to a protruding position of the power supply under test. Probes are installed in the probe through-hole, and their positions correspond to the input / output interface pin positions of the power supply under test. The host computer is connected to the voltage acquisition module and the switching control module via the communication module. The switching control module controls the power supply module and the power supply test socket, and controls the extension and retraction of the corresponding probes based on the input / output interface positions of the power supply under test.

[0008] Furthermore, the probes have different thicknesses, corresponding to the pins of the power interface under test. Below the probe is a spring seat, which is fixedly connected to the probe. Below the spring seat is a power unit, which is fixedly connected to a connecting plate of the power unit. The power unit includes a bracket, a connecting plate, a supporting cone, an armature, a support column, an electromagnet, and a coil. The connecting plate is fixedly connected to the spring seat, and one end of the connecting plate is connected to the support column via a pulley, allowing it to move up and down. The supporting cone is conical, with its apex connected to the lower surface of the connecting plate. The armature includes two metal rods fixedly connected at an obtuse angle. One end of the armature is fixedly connected to the lower surface of the supporting cone. One end of the support column is fixedly connected to the bracket, and the other end is connected to the two metal rods of the armature at an obtuse angle. One end of the electromagnet is fixedly connected to the bracket, and the other end corresponds to one end of the armature. A coil is wound around the middle of the electromagnet.

[0009] Furthermore, the host computer is used to run test software, which includes a test management module and a test report generation module. The test management module includes test templates, which include the model of the power supply under test, the size of the power supply under test, the input voltage, the output voltage, the appearance inspection requirements, the number of input test probes, the input test probe number, the number of output test probes, and the output test probe number. During testing, the test management module sends the corresponding test template to the voltage acquisition module and the switching control module through the communication module according to the model of the power supply under test.

[0010] Furthermore, the test report generation module receives data sent by the voltage acquisition module, compares the output voltage of the test template with the data sent by the voltage acquisition module, and generates a test report.

[0011] Furthermore, the power supply module includes multiple power supplies with different voltages, which supply power to the probes (10) of the power supply test socket.

[0012] Furthermore, the switching control module receives the test template sent by the host computer. Based on the input voltage, number of input test probes, and input test probe number of the test template, it controls the switching of multiple power supplies in the power supply module to control the input voltage of the corresponding probes of the power supply test socket. Based on the number of input test probes, input test probe number, number of output test probes, and output test probe number in the test template, it supplies power to the coil of the power unit under the corresponding probe. The electromagnet generates magnetic force, attracting one end of the armature. Through the lever principle of the support column, the other end of the armature is raised, the support cone fixedly connected to the other end of the armature is raised, the connecting plate connected to the support cone is raised, the spring seat fixedly connected to the connecting plate is raised, and the probe fixedly connected to the spring seat is raised, thus realizing the connection between the probe and the pin of the power interface under test. After the test, the switching control module disconnects the power supply, the electromagnet loses its magnetic force, and the probe falls down by the gravity of the spring seat and the probe, thus realizing the disconnection between the probe and the pin of the power interface under test.

[0013] Furthermore, the input test probe supplies power to the power supply under test by connecting to the input interface pin of the power supply under test.

[0014] Furthermore, the voltage acquisition module is connected to the probes of the power supply test socket to receive the test template sent by the host computer. Based on the number of output test probes and the output test probe number of the test template, the module acquires the output voltage of the power supply under test through the corresponding probes and sends the output voltage of the power supply under test to the host computer through the communication module.

[0015] Furthermore, the cover plate spring pressure column adjusts its height according to the height of the power supply under test, thus fixing the power supply under test on the power supply test socket.

[0016] This invention also provides a comprehensive testing method for power modules, comprising the following steps:

[0017] According to the model of the power supply under test, place the power supply under test in the designated position on the power supply test socket, close the cover, and fasten the lock.

[0018] The host computer's test software selects the corresponding test template based on the model of the power supply under test, and sends the test template to the voltage acquisition module and the switching control module through the communication module.

[0019] The switching control module uses the data from the test template to control the power supply module's power switch, thereby controlling the input voltage to the probes of the power supply test socket.

[0020] The switching control module then controls the corresponding probes to extend by inputting the number of test probes, inputting the test probe number, outputting the number of test probes, and outputting the test probe number of the test template. After the probes extend, they contact the input / output interface pins of the power supply under test to supply power and collect the output voltage.

[0021] The voltage acquisition module acquires the output voltage of the corresponding probe based on the number and number of the output test probes of the test template, and sends the output voltage to the host computer through the communication module.

[0022] The host computer generates a test report based on the test template and output voltage.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] (1) This invention achieves compatibility with different power supply models by using multiple probes on the power supply test socket and a switching control module, thereby improving the efficiency of power supply testing.

[0025] (2) This invention achieves power supply testing by using a probe to contact the pins of the power supply interface under test, thus achieving compatibility with different power supply interfaces. By using a unified probe contact, the cumbersome problems caused by incompatible connection ports are reduced. Furthermore, this invention provides a probe design that solves the problems of inconvenience and easy damage when testing power supplies on circuit boards.

[0026] (3) The present invention provides a test template for test software, which realizes the automation and centralization of power supply testing, improves test efficiency, and reduces the test error rate. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0035] Example 1:

[0036] This embodiment provides a comprehensive testing system for power modules, including: a host computer, a voltage acquisition module, a communication module, a power supply module, a switching control module, a power test socket, and a power supply under test. The power test socket includes a power mounting base (1), a limiting post (4), a cover plate (7), a cover plate spring pressure post (8), a latch (9), and a handle (6). The power mounting base (1) includes: a groove (2), a probe through hole (3), and a built-in fan (5). The groove (2) corresponds to the protruding position of the power supply under test. The probe through hole (3) contains a probe, the position of which corresponds to the input / output interface pin position of the power supply under test. The host computer is connected to the voltage acquisition module and the switching control module through the communication module. The switching control module controls the power supply module and the power test socket, and controls the extension and descent of the corresponding probes through the input / output interface position of the power supply under test.

[0037] like Figure 1 Figure 2 As shown, the power supply test socket includes a power supply mounting base (1), a limiting post (4), a cover plate (7), a cover plate spring pressure post (8), a latch (9), and a handle (6). The power supply test socket includes mounting bases (1) for four common types of power modules. The mounting base (1) includes a built-in fan (5), a groove, and a probe through hole. The groove size matches the power module size. The built-in fan (5) is used to cool large-sized power modules. When the power module is placed in the power supply socket, the cover plate (7) is closed, and the probes will extend from the through hole and contact the corresponding power module's input / output interface. Figure 3As shown, the probe is made of copper alloy with four pointed tips, ensuring a tight contact with the power interface and preventing slippage. When the cover is pulled down and closed, the latch automatically locks, preventing it from opening unless the button on the latch is pressed. Simultaneously, the cover plate spring-loaded post presses the power module into the base for secure installation, preventing slippage.

[0038] This invention provides a comprehensive testing system for power modules, characterized by comprising: a host computer, a voltage acquisition module, a communication module, a power supply module, a switching control module, a power supply test socket, and a power supply under test. The power supply test socket includes a power mounting base, limiting posts, a cover plate, a cover plate spring-loaded post, a latch, and a handle. The power mounting base includes a groove, a probe through-hole, and a built-in fan. The groove corresponds to a protruding position of the power supply under test. A probe is installed in the probe through-hole, and its position corresponds to the input / output interface pin position of the power supply under test. The host computer is connected to the voltage acquisition module and the switching control module via the communication module. The switching control module controls the power supply module and the power supply test socket, and controls the extension and retraction of the corresponding probes based on the input / output interface position of the power supply under test. Figure 3 Figure 4 Figure 5As shown, the probes (10) have different thicknesses, corresponding to the pins of the power interface under test. Below the probes (10) is a spring seat (11), and the probes (10) and spring seats (11) are fixedly connected. Below the spring seats (11) is a power unit (12), and the spring seats (11) and the connecting plate (14) of the power unit (12) are fixedly connected. The power unit (12) includes a bracket (13), a connecting plate (14), a supporting cone (15), an armature (16), a support column (17), an electromagnet (18), and a coil (19). The connecting plate (14) is fixedly connected to the spring seat (11), and one end of the connecting plate (14) is connected to the support column (17). The supporting cone (15) is conical and moves up and down via pulleys. The top of the supporting cone (15) is connected to the lower surface of the connecting plate (14). The armature (16) includes two metal rods, which are fixedly connected at an obtuse angle. One end of the armature (16) is fixedly connected to the lower surface of the supporting cone (15). One end of the support column (17) is fixedly connected to the bracket (13), and the other end is connected to the two metal rods of the armature (16) at an obtuse angle. One end of the electromagnet (18) is fixedly connected to the bracket (13), and the other end corresponds to one end of the armature (16). A coil (19) is wound in the middle of the electromagnet (18). The host computer runs the testing software, which includes a test management module and a test report generation module. The test management module includes test templates, which specify the model of the power supply under test, its dimensions, input voltage, output voltage, appearance inspection requirements, number of input test probes, input test probe numbers, number of output test probes, and output test probe numbers. During testing, the test management module sends the corresponding test template to the voltage acquisition module and the switching control module via a communication module based on the model of the power supply under test. The test report generation module receives data from the voltage acquisition module, compares the output voltage of the test template with the data sent by the voltage acquisition module, and generates a test report. The power supply module includes multiple power supplies with different voltages, which power the probes of the power supply test socket.The switching control module is used to receive the test template sent by the host computer. According to the input voltage, number of input test probes and input test probe number of the test template, it controls the power supply module to input voltage to the corresponding probe of the power test socket by controlling the switching of multiple power supplies of the power supply module. According to the number of input test probes, input test probe number, number of output test probes and output test probe number in the test template, it supplies power to the coil (19) of the power unit (12) under the corresponding probe (10). The electromagnet (18) generates magnetic force, attracting one end of the armature (16). Through the lever principle of the support (17), the armature (16) is pulled. The other end of the armature (16) is raised, the supporting cone (15) fixedly connected to the other end of the armature (16) is raised, the connecting plate (14) connected to the supporting cone (15) is raised, the spring seat (11) fixedly connected to the connecting plate (14) is raised, and the probe (10) fixedly connected to the spring seat (11) is raised, so as to realize the connection between the probe (10) and the pin of the power supply under test. After the test, the switching control module disconnects the power supply, the electromagnet (18) loses its magnetic force, and the probe (10) is lowered by the gravity of the spring seat (11) and the probe (10), so as to realize the disconnection between the probe (10) and the pin of the power supply under test. The length of the probe is already beyond the requirement, and as long as it extends, it will definitely be able to press into the range of spring extension and contraction. The input test probe realizes the power supply of the power supply under test by connecting to the pin of the input interface of the power supply under test. The voltage acquisition module is connected to the probes of the power supply test socket and is used to receive the test template sent by the host computer. Based on the number and number of output test probes in the test template, the module acquires the output voltage of the power supply under test through the corresponding probes and sends the output voltage of the power supply under test to the host computer via the communication module. The cover plate spring-loaded column adjusts its height according to the height of the power supply under test, thus fixing the power supply under test onto the power supply test socket.

[0039] This invention also provides a comprehensive testing method for power modules, comprising the following steps:

[0040] According to the model of the power supply under test, place the power supply under test in the designated position on the power supply test socket, close the cover, and fasten the latch. The host computer's test software selects the corresponding test template according to the model of the power supply under test and sends the test template to the voltage acquisition module and the switching control module through the communication module. The switching control module uses the data from the test template to control the power supply module's power switch, thereby controlling the input voltage to the probes of the power supply test socket. The switching control module then controls the corresponding probes to extend by using the number of input test probes, input test probe numbers, number of output test probes, and output test probe numbers of the test template. After the probes extend, they contact the input and output interface pins of the power supply under test to supply power and acquire the output voltage. The voltage acquisition module acquires the output voltage of the corresponding probe according to the number of output test probes and output test probe numbers of the test template, and sends the output voltage to the host computer through the communication module.

[0041] The host computer generates a test report based on the test template and output voltage.

[0042] The testing process is as follows: Based on the model of the power supply under test, place the power supply in the corresponding mounting bracket, and close the cover. When the cover is pulled down to close, the latch will automatically lock, preventing it from opening unless the button on the latch is pressed. Simultaneously, the cover spring posts on the cover will passively adjust their height according to the height of the power supply under test, providing spring force to press the power supply under test into the base and secure it, preventing it from sliding. The test management module of the host computer's test software selects the corresponding test template based on the model of the power supply under test. The test template includes the power supply model, dimensions, input voltage, output voltage, appearance inspection requirements, number of input test probes, input test probe number, number of output test probes, and output test probe number. The test template can be added and modified. The test management module sends the selected test template to the test report generation module, voltage acquisition module, and switching control module of the test software. The switching control module, based on the input voltage, number of input test probes, and input test probe number of the test template, controls the switching of multiple power supplies on the power supply module, controlling the input voltage of the power supply module to the corresponding probes of the power supply test socket. Based on the number of input test probes, input test probe number, number of output test probes, and output test probe number in the test template, it controls the extension of the corresponding probes. After the test, it controls the corresponding probes to fall back down. The voltage acquisition module is connected to the probes of the power supply test socket and receives the test template sent by the host computer. Based on the number of output test probes and output test probe number of the test template, it acquires the output voltage of the power supply under test through the corresponding probes and sends the output voltage of the power supply under test to the host computer via the communication module. The host computer's test report generation module generates a test report based on the test template and output voltage.

[0043] Example 2:

[0044] The parts mentioned in this embodiment are the same as those in Embodiment 1.

[0045] like Figure 6 As shown, this test system includes a host computer, a DC5V power supply, a DC12V power supply, a DC24V power supply, a DC30V voltage acquisition module, a DC220V voltage acquisition module, an AC220V voltage acquisition module, a switching control module, a small-size power module test socket 1, a small-size power module test socket 2, a small-size power module test socket 3, and a small-size power module test socket 4.

[0046] The AC220V voltage acquisition module has two sets of voltage acquisition points, capable of acquiring voltages between AC 0-500V. It also acquires the output voltage test points of large-size power supply modules converting AC220V to AC110V. The AC220V module is directly connected to the test point via a test cable. The DC220V voltage acquisition module also has two sets of voltage acquisition points, capable of acquiring voltages between DC 0-500V. It also acquires the output voltage test points of large-size power supply modules converting AC220V to DC110V. The DC220V module is directly connected to the test point via a test cable. The DC30V voltage acquisition module has nine sets of voltage acquisition points, capable of acquiring voltages between DC 0-30V. Voltage acquisition module 1 (DC30V) acquires the output voltage test points of small-size power supply modules, while voltage acquisition module 2 (DC30V) acquires the output voltage test points of large-size power supply modules converting DC24V to DC12V / 5V and AC220V to DC24V / 12V. The DC30V module is directly connected to each test point via a test cable. The power supply modules are: DC24V (AC220V to DC24V), DC12V (DC24V to DC12V), and DC5V (DC24V to DC5V). The DC24V module supplies power to the DC12V and DC5V modules. These three modules also power four small-sized power module test sockets via a switching control module. Dedicated testing software in the host computer selects the appropriate input voltage for each test socket based on the different power module models under test. The four small-sized power module test sockets are custom-designed for four commonly used power module series from our company, compatible with some power module models from the MJW, LCD, BCT, and MORNSUN / RECOM series. Each socket has probes at the corresponding pins of the power module, including probes for input voltage and probes for measuring output voltage. The power module under test is secured to the test socket by spring blocks, ensuring reliable contact with the probes at the bottom. The DC24V power supply provides DC24V operating power to the AC220V voltage acquisition module, the DC220V voltage acquisition module, and the two DC30V voltage acquisition modules. The AC220V, DC220V, and DC301-2 voltage acquisition modules, along with the switching control module, can communicate with the host computer via RS485. The host computer transmits acquisition commands to each acquisition module and control commands to the switching control module. Each acquisition module also transmits its acquired data to the host computer. The host computer is equipped with dedicated testing software, which configures the model of the power module under test, including the module type, large size, various series of small sizes, input voltage, output voltage, dimensions, and appearance inspection requirements. The testing software controls the acquisition of the output voltage, determines whether it passes the test, and automatically generates a test report.In addition, the testing software also establishes an interface with the MES system, which can automatically upload test results to the MES system, enabling automatic inspection of incoming power modules.

[0047] The original testing method involved manually powering the power module and measuring its output voltage according to the inspection requirements of various power modules. For small-sized power modules, powering them on was inconvenient, and measuring the output voltage test points was also difficult, posing a risk of incorrect input voltage or short-circuit damage to the power module. This invention provides a customized small-sized power module test socket. The probes within the test socket reliably contact the pins of the power module under test. The testing software controls the input voltage and collects the output voltage for automatic testing. The connection is reliable, easy to operate, and improves testing efficiency and accuracy.

[0048] The original testing method required manual recording of test data and judgment of pass / fail status, which carried the risk of clerical errors and misjudgments. This invention uses testing software to automatically record test data and judge test results, reducing reliance on human intervention and improving testing efficiency and accuracy.

[0049] The original testing method involved inspectors searching for the corresponding inspection work instructions based on the model of the power module under test, and then performing each inspection item according to the requirements. This invention integrates the inspection requirements into the testing software, which lists the corresponding inspection items, allowing inspectors to directly execute the instructions, thus improving testing efficiency.

[0050] The original testing method involved inspectors manually entering test results into the MES system item by item and manually tracing them through each station. This invention establishes an interface between the testing software and the MES system, enabling automatic uploading and tracing of test results, thus improving testing efficiency.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
