Description

Automatic aging test system for power supply product

Technical Field

The invention relates to the technical field of electronic power, in particular to an automatic aging test system of a power supply product.

Background

With the rapid development of technology, many modern electronic products, electrical equipment, and electric appliances need to be supplied with their required power by a power supply. Therefore, manufacturers are actively developing various power supply products (abbreviated as power supply products) suitable for different devices. It should be noted that after manufacturing, the power product must undergo a burn-in test (burn-in test) before shipment. The purpose of carrying out burn-in test on the power supply product is to verify the stability and reliability of the product, thereby ensuring the shipment quality.

Fig. 1 shows a burn-in test architecture diagram of a conventional power supply product. As shown in fig. 1, after a power source 2a is coupled to an input terminal of a power product 1a (e.g., a power converter) and a load device 3a is coupled to an output terminal of the power product 1a, the power product 1a may start to perform a burn-in test. The load device 3a shown in fig. 1 is, for example, a resistor. In this example, the power product 1a receives a first power signal (ac or dc) transmitted by the power source 2a, and outputs a second power signal to the load device 3a after performing a power conversion process on the first power signal. It should be understood that the second power signal is converted into heat energy after being input into the load device 3a, which results in energy waste.

In view of this, manufacturers have improved the burn-in test structure of the conventional power supply product, i.e. the burn-in test structure of the conventional power supply product shown in fig. 2. As can be easily understood by comparing fig. 2 and fig. 1, in the burn-in test architecture of the conventional power supply product, a power supply 2a is coupled to an input terminal of a power supply product 1a (e.g., a power converter), and an electronic load device 3b is coupled to an output terminal of the power supply product 1 a. When the aging test is executed, the electronic load device 3b can further convert the second power signal output by the power supply product 1a into a third power signal, and then return the third power signal to the input end of the power supply product 1a, so as to achieve the effect of recycling energy, thereby effectively avoiding energy waste. Therefore, the manufacturer also refers to the electronic load device 3b as an Energy saving burn-in system (ERS).

Unfortunately, practical experience has indicated that the burn-in test architecture of the conventional power supply product of fig. 2 still has many drawbacks. For example, the burn-in test procedure of the power product 1a is performed by manual operations, including installing the power product 1a on the computer, setting the burn-in conditions (current and/or voltage), and recording test data. It should be understood that the manual operation is difficult to avoid the erroneous operation of the burn-in condition setup and/or data recording due to carelessness, so that the related burn-in test data related to the power product 1a is lack of reliability, and finally, the time and cost are wasted. To be more specific, the burn-in condition is different according to the type and model of the power product 1a, so if the burn-in condition is set incorrectly due to careless manual operation, the burn-in test cannot perfectly and effectively verify the reliability and stability of the power product 1a, and finally the shipment quality of the power product 1a cannot be effectively controlled.

From the above description, the burn-in test structure of the conventional power supply product still has room for further improvement. Accordingly, the inventor of the present invention has made research and creation to the utmost extent, and finally, the invention provides an automatic aging test system for power products.

Detailed Description

In order to more clearly describe the automatic burn-in test system of the power supply product of the present invention, the preferred embodiment of the present invention will be described in detail below with reference to the drawings.

Referring to fig. 3, a first architecture diagram of an automated burn-in test system for power products according to the present invention is shown. As shown in fig. 3, the present invention provides an automated burn-in test system for performing a burn-in test on at least one power product 3. According to the design of the invention, the automatic aging test system mainly comprises: a power supply device 1, at least one electronic load device 4 and a control management device 5. It should be noted that, in the burn-in test, the power products 3 (at least one) to be tested are placed in a special test cabinet. After being placed in the testing cabinet, the power product 3 is coupled between the power device 1 and the electronic load device 4. In more detail, the power device 1 is coupled to a power input port of the at least one power product 3. On the other hand, the electronic load device 4 is coupled to a power output port of the power product 3 corresponding to the electronic load device through a power input port thereof, and is coupled to the power input port of the power product 3 through a power output port thereof. Further, the control management device 5 couples the at least one electronic load device 4 and the power supply device 1.

It should be understood that there are many kinds of power supply products 3 to be tested, including: a Power converter (Power converter), a Power supply (Power supply), a Power adapter (Power adapter), a Charger (Charger), or a light driving device (such as an LED driver). Accordingly, the power supply apparatus 1 may be variously classified into: a commercial power supply device, a power conversion device, or a power supply device.

With continuing reference to FIG. 3 and with further reference to FIG. 4, a second architecture diagram of the automated burn-in system of the present invention is shown. It has to be specifically explained that in general, a plurality of power products 3 of the same kind can be put into the cabinet at the same time, so that the burn-in test is performed together in batches. This is particularly illustrated in fig. 4 for ease of reading and understanding. When performing the batch burn-in test, a switching unit 8 is coupled between the control management device 5, the power device 1, and the at least one power product 3, and is configured to transmit a first power signal provided by the power device 1 to a plurality of the power products 3 according to the control of the control management device 5.

Continuing to refer to FIG. 3, and referring also to FIG. 5, a block diagram of the control management device is shown. According to the design of the present invention, the control management device 5 includes a first processor unit 501, a second processor unit 502, a network interface 51, a communication interface 52, a human-machine interface 53, an input/output interface 54, and an expansion communication interface 55. The first processor unit 501 is coupled to the network interface 51, the human-machine interface 53 and the expansion communication interface 55, and the second processor unit 502 is coupled to the first processor unit 501, the communication interface 52 and the input/output interface 54. More specifically, the network interface 51 communicatively couples a remote monitoring system 6 and an information management system 7 via a network. The communication interface 52 is configured to transmit a first control signal to the electronic load device 4 via a first communication protocol and to receive a burn-in test data transmitted by the electronic load device 4 via the first communication protocol. As shown in fig. 5, the network interface 51 includes an FTP communication unit, an SMTP communication unit, a TCP/IP communication unit, an MQTT communication unit, and a Web server communication unit, so that the network interface 51 can utilize at least one communication unit to realize the network communication. It should be noted that fig. 5 is a functional block diagram showing the network interface 51 having the functions of FTP, SMTP, TCP/IP, MQTT, Web server, etc., and therefore, the relevant reference symbols are not marked to avoid the content of fig. 5 being too miscellaneous for reading.

Furthermore, as shown in fig. 5, the communication interface 52 includes an RS485 communication unit, an RS232 communication unit, a CANBus communication unit, and a PMBus communication unit to implement the first communication protocol. Similarly, FIG. 5 is a functional block diagram illustrating the communication interface 52 having RS485, RS232, CANBus, and PMBus communication functions, and therefore no reference numerals are used to indicate any more related components to avoid over-hybridization of the contents of FIG. 5, which is advantageous for reading. Meanwhile, the control management device 5 further transmits a second control signal to the power device 1 through the first communication protocol by using the communication interface 52.

As can be seen from fig. 5, the human-machine interface 53 includes: the device comprises a display, an input unit, an operation interface, a Real-time clock (RTC) unit, a memory unit and an event LOG (LOG) unit. Further, fig. 6A and 6B show display screen views of the human-machine interface of the control management apparatus. According to the design of the present invention, the operation of the human-machine interface 53 can control the control management device 5 to perform the following operations: the information management system 7 acquires a production task instruction sheet (work order) and a parameter set for burn-in test, performs an automatic parameter setting program on the electronic load device 4 and the power supply device 1, and controls the electronic load device 4 and the power supply device 1 to perform burn-in test on at least one of the power supply products 3. As shown in fig. 3, after the power product 3 is placed in the testing cabinet, it is coupled between the power device 1 and the electronic load device 4. At this time, as shown in fig. 6A and 6B, the human-machine interface 53 is operated to enable the control management device 5 to obtain a production task order (e.g., a work order) and a set of aging test parameters corresponding to the power product 3 from the information management system 7 (e.g., ERP system). Then, the control management device 5 performs an automatic parameter setting procedure on the electronic load device 4 and the power supply device 1 according to the production task instruction sheet and the aging test parameter set, so that the power supply device 1 transmits a first power signal to the power input port of at least one of the power products 3.

As described above, after receiving the first power signal, as shown in fig. 3, the power product 3 converts the first power signal into a second power signal, and then transmits the second power signal to the corresponding electronic load device 4, so that the electronic load device 4 converts the second power signal into a third power signal and then transmits the third power signal back to the power input port of the corresponding power product 3. After the burn-in test of each of the power products 3 is completed, the control and management device 5 receives the burn-in test data transmitted from each of the electronic load devices 4, and then transmits the burn-in test data to the remote monitoring system 6 and/or the information management system 7.

As can be seen from the foregoing description, the automated burn-in test system of the present invention does not require any manual parameter setting and test data arrangement for the power supply device 1 and/or the electronic load device 4. It is easy to understand that the automatic aging test system of the invention can effectively verify the reliability and stability of various power products 3 without manually setting parameters and sorting test data, thereby effectively controlling and managing the shipment quality of the power products 3. On the other hand, as can be seen from fig. 6A and 6B, since the aging test of each cabinet is managed by the industrial order in the present invention, the remote monitoring system 6 and the information management system 7 (e.g., ERP system) at the back end can clearly manage all the aging test data according to the building (the number of the building), the floor (the number of the building), the area, and the cabinet for test (cabinet number or IP), thereby completely avoiding the error of manually managing and recording data.

As shown in fig. 3 and fig. 5, in one possible embodiment, the control management device 5 further includes an input/output interface 54 and an expansion communication interface 55. The i/o interface 54 is used to couple a signal input device and/or a signal receiving device, and includes an analog i/o unit, a digital i/o unit, and a switch control unit. In more detail, fig. 6A and 6B show the display screen of the human-machine interface 53 displaying the function keys of "keyboard input", i.e. a signal input device (keyboard) is coupled to the input/output interface 54. On the other hand, the expansion communication interface 55 is used for enabling the control management device 5 to perform data transmission with an external electronic device by using a second communication protocol, and the expansion communication interface 55 includes a ZigBee communication unit, a bluetooth communication unit, a NBIoT communication unit, a LoRA communication unit, a GSM communication unit, and an EnOcean communication unit to implement the second communication protocol. Similarly, fig. 5 is a functional block diagram showing that the expansion communication interface 55 has the expansion communication functions of ZigBee, Bluetooth, NBIoT, LoRA, GSM, and EnOcean, so that the relevant reference symbols are not marked to avoid the content of fig. 5 from being too mixed, which is beneficial for reading.

Thus, all embodiments of the automated burn-in test system for power products disclosed herein have been fully and clearly illustrated. It should be emphasized that the above detailed description is specific to possible embodiments of the invention, and such embodiments are not intended to limit the scope of the invention, as such equivalent implementations or modifications should be included within the scope of the present invention without departing from the technical spirit of the invention.
