Description

Technical Field

[0001] The present invention relates to the technical field of LED testing, and in particular to an LED lamp panel lighting test device and system. Background Art

[0002] In the LED light panel production process, lighting testing is a critical step in ensuring product quality and performance. Currently, the industry primarily uses two lighting testing methods: one is through hard connection to the product connector, and the other is through wireless transmission at the lighting station. Figure 1 This is one of the structural diagrams of the LED light panel lighting detection system in the prior art, which adopts the first connection method, such as Figure 1 As shown, the LED light panel is mounted on connector 1, and connector 2 is mounted on the fixture. Connectors 1 and 2 are hard-wired. During testing, connector 1 varies in style and type depending on the LED product, so connector 2 must also be replaced as connector 1 changes. The fixture automatically moves and operates at different stations during production and testing. When it reaches the testing and lighting station, connector 3 on the fixture is hard-wired to connector 4 at the corresponding station. This hard-wired approach presents the following problems:

[0003] On the one hand, connector 1 changes with each LED panel product replacement, but the repetition frequency is low. Connectors 2 and 3 are installed on the jig, and connector 2 must match connector 1. When the jig is replaced, connectors 2 and 3 must be replaced at the same time. Connector 4, on the other hand, is fixed to the equipment and is frequently used. However, high-precision connectors are easily worn during frequent plugging and unplugging, which can lead to data transmission anomalies and seriously affect the equipment's detection accuracy and efficiency. This not only increases maintenance costs during the production process, but can also lead to increased product defect rates, reducing production efficiency and product quality.

[0004] Figure 2 This is the second structural diagram of the LED light panel lighting detection system in the existing technology. In order to solve the problem of connector wear in the hard connection method, the industry has introduced a second lighting test method, such as Figure 2 As shown, this approach replaces the hard-wired approach with a millimeter-wave wireless transmission module, enabling wireless data and power transmission. However, this wireless transmission approach has practical limitations, including complex power supply regulation, high maintenance costs, and complex debugging.

[0005] In summary, the two existing LED light board lighting test systems cannot meet the requirements of efficient, stable and low-cost testing of LED light boards. Summary of the Invention

[0045] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] Since different types of LED light panels have different power supply currents, the wireless power supply module needs to be compatible with different types of transmission distances, which makes power supply adjustment complicated. Complex power supply adjustment will lead to higher maintenance costs of the equipment. In addition, due to the strict distance restrictions between wireless power supply modules, the operation will also be more complicated during actual use and debugging.

[0047] In order to solve the above problems, this application establishes a relationship table between the distance between the wireless transmission sending module and the wireless transmission receiving module and the voltage and current, establishes a relationship table between the LED light board model and the current and voltage required for its production test, and establishes a relationship table between the distance between the wireless transmission sending module and the wireless transmission receiving module and the product model, and pre-stores the relationship table on the PC for user use. Specifically, the three relationship tables are imported into the production and testing software on the PC. When the user selects the corresponding product model on the PC, the PLC program will send a signal to the distance adjustment mechanism set on the wireless transmission sending module, and the distance between the wireless transmission sending module and the wireless transmission receiving module will be automatically adjusted by the distance adjustment mechanism until the distance meets the corresponding model requirement, so as to solve the power supply requirements of each product model and thus meet the production and testing requirements of different LED light boards.

[0048] The three relationship tables mentioned above are given below as examples, see Tables 1 to 3 for details.

[0055] Figure 3 This is a schematic diagram of the structure of the LED light board lighting detection device of this application, such as Figure 3 As shown, it includes: a wireless transmission sending module 1, which is used to receive relevant parameter information from LED light boards of different models, and encode and encapsulate the relevant parameter information according to a predefined communication protocol, and then send it to the wireless transmission receiving module through a wireless signal, so that the wireless transmission receiving module can parse and process it, and control the lighting of the LED light board accordingly according to the analysis results; it is also used to obtain the input current and voltage corresponding to each model, and based on the input current and voltage, light up the LED light board of the corresponding model; a distance adjustment mechanism 2, which is used for a distance adjustment mechanism, and the distance adjustment mechanism is used to obtain the wireless transmission distance corresponding to a specific LED model, and adjust the distance between the wireless transmission sending module and the wireless transmission receiving module according to the wireless transmission distance.

[0056] Specifically, the wireless transmission module is responsible for receiving relevant parameter information from different models of LED light boards. This parameter information includes but is not limited to the timing information, clock information, RGB information, input current, voltage, wireless transmission distance, etc. corresponding to each model of LED light board.

[0057] The wireless transmission module encodes and encapsulates the received timing information, clock information, and RGB information according to a predefined communication protocol and transmits the encapsulated information to the wireless transmission receiving module via wireless signals. A distance adjustment mechanism adjusts the distance between the wireless transmission module and the wireless transmission receiving module based on the wireless transmission distance corresponding to a specific LED light panel model to meet the power supply requirements of different LED light panels during production and testing. The distance adjustment mechanism can be mounted on the equipment rack or on the wireless transmission module.

[0058] The user enters the LED model number on the PC. The PC then retrieves the input current, voltage, and distance information corresponding to that specific LED model based on pre-stored Tables 1-3. The PC then transmits this specific information to the wireless transmission module. Upon receiving this information, the wireless transmission module uses a distance adjustment mechanism to adjust the distance between itself and the wireless transmission receiving module based on the distance information corresponding to the specific LED model. Simultaneously, the wireless transmission module controls the power supply to the LED panel under test based on the received input current and voltage information.

[0059] In existing technologies, the distance between wireless power modules is strictly limited, and different types of LED panels have different supply currents, resulting in complex power regulation and high maintenance costs. The distance adjustment mechanism automatically adjusts the distance between the transmitting and receiving modules based on the LED panel model, simplifying the power adjustment process and resolving the complexity of power regulation in existing millimeter-wave wireless transmission methods.

[0060] The LED light panel lighting test device provided in this application, on the one hand, uses a distance adjustment mechanism to adjust the distance between the wireless transmission sending module and the wireless transmission receiving module, thereby avoiding the problem of abnormal data transmission caused by connector wear in traditional hardware connection methods, thereby improving the stability and service life of the device; on the other hand, it simplifies the power supply adjustment process. In addition, the wireless transmission sending module receives relevant parameter information from different models of LED light panels, encodes and encapsulates the relevant parameter information according to a predefined communication protocol, and sends it to the wireless transmission receiving module via wireless signals. This allows the same test device to be applied to multiple models of LED light panels, thereby reducing production and maintenance costs.

[0061] Furthermore, the wireless transmission sending module includes: the wireless transmission sending module includes: a configuration module M10-1, which is used to obtain the input current, voltage, and communication protocol corresponding to different models of LED light boards from the PC end; and use the input current and voltage to light up the corresponding LED light board; the configuration module M10-1 is also used to configure the timing information, clock information, and RGB information according to the communication protocol, and send the configured timing information, clock information, and RGB information to the wireless transmission receiving module, so that the wireless transmission receiving module controls the timing, frequency, and color of the corresponding model of LED light board.

[0062] Specifically, configuration module M10-1 connects to a PC via a LAN port and retrieves the input current and voltage parameters corresponding to different LED panel models from the PC's production and testing software. These parameters are pre-stored on the PC, with fixed input current and voltage requirements for each LED panel model. Configuration module M10-1 uses these input current and voltage parameters to illuminate the corresponding LED panel. Furthermore, configuration module M10-1 retrieves the communication protocol required to illuminate the LED panel from the PC. This protocol defines the data transmission format. Based on the acquired communication protocol, configuration module M10-1 configures the timing, clock, and RGB information it receives. The timing information determines the order and time intervals for the LED panels to illuminate; the clock information ensures synchronization of data transmission; and the RGB information defines the color of the LED panels. By configuring this information using the communication protocol, configuration module M10-1 achieves precise control over the lighting effect of the LED panels. Configuration module M10-1 sends the configured timing, clock, and RGB information to the wireless transmission and reception module. Upon receiving this information, the wireless transmission and reception module parses and processes the encoded and encapsulated timing signals, RGB information, and clock information based on the communication protocol corresponding to the model, and controls the lighting of the LED light board accordingly based on the parsed results.

[0063] The LED light board lighting test device provided in this application obtains the input current, voltage and communication protocol corresponding to different models of LED light boards from the PC side through the configuration module M10-1, thereby meeting the lighting requirements of different models of LED light boards and improving the flexibility and adaptability of the device. Moreover, the user does not need to manually adjust the hardware parameters or write complex program codes to adapt to different models of LED light boards. Only simple configuration operations on the PC side are needed to realize the lighting control of the LED light board, which greatly simplifies the operation process and improves work efficiency; it also reduces labor costs and time costs, while reducing the additional costs caused by frequent replacement and debugging of hardware. In addition, when it is necessary to update or adjust the configuration, it is only necessary to make corresponding modifications to the M10-1 module without making large-scale changes to the entire device. This reduces the difficulty and cost of maintenance and improves the reliability and service life of the device.

[0064] Furthermore, the wireless transmission sending module also includes: a wireless power supply B module, which is used to power the configuration module M10-1 and the LED light board under test; a distance adjustment mechanism is used to adjust the distance between the coil of the wireless power supply B module and the coil of the power supply module on the wireless transmission receiving module, so that the adjusted distance matches the corresponding model of the LED light board.

[0065] Specifically, the wireless transmission and transmission module includes a wireless power supply module B, while the wireless transmission and reception module is also equipped with a wireless power supply module. These two wireless power supply modules perform contactless power transmission through electromagnetic induction or similar principles. This application utilizes a distance adjustment mechanism to adjust the distance between the coil of the wireless power supply module B and the coil of the power supply module on the wireless transmission and reception module to accommodate the power supply requirements of different LED light board models. When testing a specific LED light board model, the user first selects the corresponding product model on a PC. The PC's production and testing software, based on preset parameters, transmits information such as the input current, voltage, and communication protocol required for that LED light board model to the configuration module M10-1. Upon receiving this information, the configuration module M10-1 uses the input current and voltage to illuminate the LED light board and transmits the configured timing information, clock information, RGB information, and other information to the wireless transmission and reception module. Simultaneously, the distance adjustment mechanism automatically adjusts the distance between the coil of the wireless power supply module B and the coil of the power supply module on the wireless transmission and reception module based on the wireless transmission distance corresponding to the specific LED light board model, until the distance meets the requirements for the corresponding model.

[0066] like Figure 3 As shown, the distance adjustment mechanism provided in this application includes: a limiter 21 and a cylinder 22; the limiter 21 is used to limit the position of the cylinder 22 to rise and press down, and the cylinder 22 is used to drive the wireless transmission sending module 1 to move up and down.

[0067] Specifically, the present invention does not limit the specific structure of the distance adjustment mechanism, as long as it can adjust the distance between the coil of the wireless power supply B module and the coil of the power supply module on the wireless transmission receiving module. Below, an embodiment of the present invention gives a specific structure of a distance adjustment mechanism as an example. In an embodiment of the present application, the limiter includes: a downward limiter and a lifting limiter. A PLC control module is provided on the distance adjustment mechanism, and the PLC control module is connected to the PC end to obtain the wireless transmission distance that needs to be adjusted from the PC end. The process of adjusting the wireless transmission distance is as follows:

[0068] In the initial state, the cylinder is in the downward position, and the wireless transmitter module is in its initial working position. At this point, the downward limiter is triggered, sending a signal to the PLC control module, indicating that the cylinder has reached its downward limit. When the position of the wireless transmitter module needs to be adjusted, the PLC control module issues a command to control the cylinder's solenoid valve, causing the cylinder piston rod to extend upward. The cylinder moves upward, carrying the wireless transmitter module with it. When the cylinder piston rod rises to the predetermined position, the upward limiter is triggered, sending a signal to the PLC control module. Upon receiving this signal, the PLC control module immediately cuts off the upward power to the cylinder, stopping the cylinder's movement. At this point, the wireless transmitter module reaches its raised working position. When the wireless transmitter module needs to be restored to its initial position, the PLC control module issues a command to control the cylinder's solenoid valve to retract the cylinder piston rod. The cylinder moves downward, carrying the wireless transmitter module with it. When the cylinder piston rod descends to its initial position, the downward limiter is triggered again, sending a signal to the PLC control module. After receiving the signal, the PLC control module cuts off the downward power of the cylinder, stops the cylinder from moving, and the wireless transmission sending module returns to the initial working position.

[0069] The present invention also provides an LED light board lighting test device, a wireless transmission receiving module, which is used to receive relevant parameter information of different models of LED light boards from the wireless transmission sending module. The relevant parameter information of the LED light board is encoded and packaged by the wireless transmission sending module according to a predefined communication protocol and then sent; the wireless transmission receiving module is also used to obtain the predefined communication protocol from the PC end, and based on the communication protocol, parse and process the relevant parameter information of the LED light board sent from the wireless transmission sending module, and control the lighting condition of the LED light board accordingly according to the parsing result.

[0070] Specifically, the wireless transmission receiving module is responsible for receiving parameter information related to different models of LED light panels from the wireless transmission transmitting module. Before transmission, this parameter information is encoded and encapsulated by the wireless transmission transmitting module according to a predefined communication protocol. The encoding and encapsulation operations ensure the accuracy, integrity, and security of the data during wireless transmission. The wireless transmission receiving module also needs to obtain the same communication protocol from the PC as the wireless transmission transmitting module. This is because the receiving module needs to parse and process the received parameter information according to the same protocol rules. Once the parameter information is received, the receiving module parses it according to the acquired communication protocol and extracts key parameters such as timing information, clock information, and RGB information. Based on the parsed and processed results, the wireless transmission receiving module generates corresponding control signals to control the lighting of the LED light panel. For example, the timing information controls the lighting and extinguishing order of each pixel on the LED light panel, and the RGB information adjusts the color displayed by each pixel, thereby enabling lighting testing of different models of LED light panels.

[0071] The device provided by the present invention adopts a wireless transmission receiving module to receive information, and does not require hard connection of connectors, which fundamentally avoids the wear problem of connectors due to repeated plugging and unplugging, thereby reducing the negative effects of increased maintenance costs, increased product defective rates and reduced production efficiency caused by connector wear, and ensuring the detection accuracy and efficiency of the equipment; in addition, the wireless transmission receiving module receives relevant parameter information of different models of LED light boards that are encoded and packaged according to a predefined communication protocol, and obtains the same communication protocol as the sending module from the PC side for parsing, processing and control. Compared with the existing wireless transmission method that directly uses the millimeter wave wireless transmission module, it simplifies the power supply adjustment process, reduces maintenance costs and debugging difficulty, and is more conducive to meeting the needs of efficient, stable and low-cost testing of LED light boards.

[0072] Furthermore, the wireless transmission receiving module includes: a configuration module M10-2 and a wireless power supply A module; the configuration module M10-2 is used to obtain the communication protocol from the PC side, and based on the communication protocol, parse and process the relevant parameter information of the LED light board sent from the wireless transmission sending module, and control the lighting status of the LED light board accordingly according to the analysis results; the wireless power supply A module is used to power the configuration module M10-2.

[0073] Specifically, configuration module M10-2, serving as the core data processing unit of the wireless transmission receiving module, first establishes a communication connection with the PC and retrieves a predefined communication protocol from the PC. When the wireless transmission sending module encodes and packages the relevant parameter information of different LED light panels according to the communication protocol and sends it, configuration module M10-2 parses and processes this received information based on the acquired communication protocol. Finally, based on the parsed results, configuration module M10-2 generates corresponding control signals to control the lighting of the LED panels, such as adjusting their brightness and switching their colors.

[0074] The device provided by the present invention obtains the communication protocol from the PC side through the configuration module M10-2, and parses and processes the relevant parameter information of the received LED light boards of different models according to the communication protocol, so that the device can adapt to the testing requirements of various models of LED light boards and has good versatility and adaptability.

[0075] Figure 4 This is a schematic diagram of the LED light panel lighting test system provided by the present invention, as shown in FIG. Figure 4 As shown, the system includes:

[0076] The PC is used to store parameter information corresponding to a plurality of different LED light board models, and transmit part of the parameter information to the transmitter based on the specific LED light board model input by the user; the parameter information includes: the model of each LED light board, the communication protocol corresponding to each model, the input current and voltage corresponding to each model, and the wireless transmission distance; the part of the parameter information includes: the model of each LED light board, the communication protocol corresponding to each model;

[0077] The transmitter is used to receive part of the parameter information, perform preliminary processing on the part of the parameter information, and then send it to the receiving card;

[0078] A receiving card is used to convert the processed parameter information into timing signals, RGB information and clock information required for normal operation of the LED light board;

[0079] The wireless transmission sending module is used to receive the timing signals, RGB information and clock information corresponding to different models of LED light boards, encode and encapsulate the timing signals, RGB information and clock information according to the communication protocol corresponding to the corresponding model, and then send them to the wireless transmission receiving module via wireless signals for the wireless transmission receiving module to parse and process them, and control the lighting of the LED light board accordingly based on the parsing results; it is also used to obtain the input current and voltage corresponding to each LED light board model, and light up the corresponding model of LED light board based on the input current and voltage;

[0080] A distance adjustment mechanism is used to obtain the wireless transmission distance corresponding to a specific LED model and adjust the distance between the wireless transmission sending module and the wireless transmission receiving module according to the wireless transmission distance;

[0081] The wireless transmission receiving module is used to obtain the same communication protocol as the wireless transmission sending module from the PC, parse and process the received relevant parameter information of the LED light board, and control the lighting of the LED light board accordingly according to the analysis results.

[0082] Among them, the wireless transmission sending module includes: a configuration module M10-1, which is used to obtain the input current and voltage corresponding to different models of LED light boards from the PC end; and use the input current and voltage to light up the corresponding LED light board; the configuration module M10-1 is also used to configure the timing information, clock information, and RGB information according to the communication protocol, and send the configured timing information, clock information, and RGB information to the wireless transmission receiving module, so that the wireless transmission receiving module can control the lighting of the LED light board.

[0083] The wireless transmission and receiving module includes: a configuration module M10-2 and a wireless power supply A module; the configuration module M10-2 is used to obtain a communication protocol from the PC, and based on the communication protocol, parse and process the received timing signal, RGB information and clock information, and control the lighting of the LED light board accordingly according to the analysis results; the wireless power supply A module is used to power the configuration module M10-2.

[0084] Specifically, the existing millimeter-wave wireless transmission method is a one-way, point-to-point transmission method. This means that when the data configuration of one end (such as the transmitter) changes, it is difficult for the other end (such as the receiver) to automatically adapt to these changes. Moreover, during the production and testing of LED light panels, different LED light panel models may require different lighting parameters. However, if the receiving card program is designed as a universal product, then each time a new LED light panel is replaced, a program must be developed based on the characteristics of the panel to adjust the lighting parameters. This customized development process not only increases costs, but also prolongs the development cycle and affects production efficiency.

[0085] To this end, this application adds a configuration module M10-1 to the wireless transmission module to individually configure the LED light board configuration data sent by the receiving card. By adding a configuration module M10-2 to the receiving end of the wireless transmission module, when the LED light board model is changed, only the configuration modules M10-1 and M10-2 need to be adjusted accordingly on the PC side, without having to redevelop the entire receiving card program. This method greatly reduces development costs and cycles and improves production efficiency.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
