Description

[0001] This application is a divisional application of application number 202422933754.4, filed on November 29, 2024, entitled "Display Screen Testing System". The full text of the original application is incorporated herein by reference. Technical Field

[0002] This application relates to the field of display screen testing technology, and in particular to the design of a trolley, an aging test furnace, and a display screen testing system. Background Technology

[0003] Before leaving the factory, in addition to screen testing to determine if there are any display abnormalities, displays also need to undergo aging tests to ensure stable performance during later use.

[0004] An aging furnace for aging tests typically has several compartments (e.g., four) to house the displays to be tested and trolleys equipped with multiple pattern generators (PGs). The pattern generators acquire screen data from an external computer (referred to in the industry as the host computer) and use this data to display the test image on the screen under test. For example, if the aging furnace has four compartments, four trolleys are typically pushed into the compartments for subsequent testing. The overall testing architecture is as follows: After the trolley containing the graphics generator is pushed into the corresponding compartment of the aging furnace, the power connector is connected to establish power and communication lines. Power is supplied from the power source within the aging furnace to start the graphics generator. Once started, the graphics generator creates UDP-based network communication sockets according to the IP address set by the DIP switch and the program-defined ports 3956 (command port) and 43690 (data port). Simultaneously, the external computer device creates two UDP-based network communication sockets. These two sockets interact with the graphics generator using two open local ports on the computer device (e.g., 3957 and 5002), a target IP address, and a target port. The target IP address and target port are respectively the graphics generator's IP address + command port and IP address + data port. Control of the graphics generator is achieved through a network link via a network cable and a switch, based on the above software design.

[0005] Under this control system, a single computer device needs to issue control commands to hundreds of graphics generators, and the IP address mappings that establish communication connections between the computer device and these hundreds of graphics generators are predetermined, for example: 1. Before conducting the aging test, the personnel responsible for installing the trolley will manually assign the IP address of each graphics generator to a fixed address. Assuming there are 200 graphics generators participating in this aging test, the IP address of PG1 will be assigned to 192.168.5.1, the IP address of PG2 will be assigned to 192.168.5.2, ..., the IP address of PG200 will be assigned to 192.168.5.200; PG1-PG18 will be placed on the first trolley, PG19-PG36 will be placed on the second trolley, ..., and the corresponding first trolley will be placed in the first compartment. 2. When the computer equipment establishes communication, it automatically assumes that the first vehicle is placed in the first compartment, and that the IP address range of each PG in the first compartment is 192.168.5.1-192.1168.5.18. Therefore, in practice, the computer equipment sends control commands for PG1 to the IP address of 192.168.5.1, and control commands for PG18 to the IP address of 192.168.5.18. In other words, if the second vehicle is mistakenly placed in the first compartment, the target IP address in the socket for sending commands and data to the first compartment will still be 192.168.5.1-192.1168.5.18. However, since the IP addresses of the graphics generators in the second vehicle are 192.168.5.19-192.1168.5.36, normal communication cannot be established.

[0006] However, in practical applications, because each compartment of the aging furnace requires frequent changes to equipment and products under test, the trolleys within the compartments are frequently pushed forward and pushed back. Since aging test lines are typically configured with multiple lines (assuming four test lines, each with four compartments), there are a total of 16 trolleys corresponding to each compartment. Therefore, during the frequent pushing and pushing of trolleys, it is easy to mix up trolleys from adjacent compartments. When pushing a compartment back, a trolley often fails to move into its corresponding compartment, leading to communication errors and impacting work efficiency. Furthermore, because each compartment has a fixed IP address, the spare trolley for each compartment (a spare trolley is a replacement material used when a working trolley malfunctions) can only be used by that compartment. If a trolley in another compartment malfunctions, the spare trolley cannot be used directly; the IP address information of the PG on the spare trolley must be manually changed, making aging testing extremely cumbersome and affecting production line efficiency. Summary of the Invention

[0007] In view of this, this application proposes a display screen testing system.

[0008] The display screen testing system proposed in this application includes: Computer equipment used to provide point-and-shoot data; Multiple trolleys are equipped with multiple graphics generators.

In addition, the computer equipment can also determine the IP address of each graphics generator on the trolley based on the identified trolley identity, so as to establish a communication connection with them and correctly send the dot screen data.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application 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 this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0023] In the description of this application, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0024] The following is combined Figure 1 This application describes a display screen testing system capable of performing aging tests on display screens. The system includes a computer device 10, multiple trolleys 30, and an aging test furnace 20. The computer device 10 may be a PC, used to provide screen data. Each trolley 30 is equipped with multiple pattern generators 31, which acquire screen data from the computer device 10 and display a test image on the screen under test based on the acquired screen data. The aging test furnace 20 has multiple compartments 21 for accommodating the trolleys 30. Each trolley 30 can move into and out of any of the compartments 21. To facilitate the movement of the trolleys 30, casters can be installed at the bottom of the trolleys 30.

[0025] In addition, the system includes a plurality of first identifiers 32 and a plurality of second identifiers 22. The plurality of first identifiers 32 are correspondingly disposed on a plurality of trolleys 30 to identify the trolleys 30 by means of their distinct first identifier information. The plurality of second identifiers 22 are correspondingly disposed in a plurality of compartments 21 to identify the compartments 21 by means of their distinct second identifier information. Each of the first identifiers 32 is operatively communicatively connected to each of the second identifiers 22 and the computer device 10 to obtain corresponding second identifier information from the second identifier 22 and transmit the second identifier information and the corresponding first identifier information to the computer device 10.

[0026] Specifically, the first identifier 32 can generate first identifier information, and the second identifier 22 can generate second identifier information. Since each first identifier 32 is respectively set on each trolley 30, and each second identifier 22 is respectively set in each compartment 21, as long as the first identifier information generated by each first identifier 32 is different from each other, and the second identifier information generated by each second identifier 22 is different from each other, the computer device 10 can determine which trolley 30 is currently arranged in which compartment 21 based on the first identifier information and the second identifier information obtained from the first identifier 32, so as to guide the computer device 10 to perform subsequent operations based on the information, such as establishing a communication link with the corresponding graphics generator 31 to send screen data to it.

[0027] In this embodiment, after the trolley 30 is moved into the target compartment 21, the first identifier 32 on the trolley 30 can be made to communicate with the computer device 10 and the second identifier 22 in the compartment 21 through relevant operations, so that the first identifier 32 can obtain the corresponding second identifier information from the second identifier 22 and transmit the second identifier information and the corresponding first identifier information to the computer device 10.

[0028] In this embodiment, all graphics generators 31 on the multiple carriages 30 have different preset IP addresses. This ensures that the computer device 10 can communicate with at least all graphics generators 31 and simultaneously send screen display data to them. For each carriage 30, the first identification information of its first identifier 32 and the preset IP address of each graphics generator 31 on it are pre-stored in the computer device 10 in a mutually associated manner. Thus, when the computer device 10 obtains the first identification information of the first identifier 32 on the carriage 30, it can determine the IP address of each graphics generator 31 on the current carriage 30 based on the association relationship, and then send screen display data to the graphics generator 31 on that carriage 30 based on that IP address.

[0029] In this embodiment, the computer device 10 may include a display, which is operable to display the aforementioned first identification information and second identification information. During operation, the operator can observe the first identification information and second identification information displayed by the computer device 10 through the display. In one example, the display of the computer device 10 shows that the current No. 2 trolley 30 is in the No. 1 compartment 21, and the No. 1 trolley 30 is in the No. 2 compartment 21. Based on this, the operator can, as needed, operate the computer device 10 to send screen data to the graphics generator 31 on the No. 2 trolley 30 (or the graphics generator 31 on the No. 1 trolley 30) so that the test display screen in the No. 1 compartment 21 displays the test screen. In the aforementioned example, when the operator operates the computer device 10 as needed to send screen data to the graphics generator 31 on the No. 2 trolley 30 so as to display the test screen in the No. 1 compartment 21, the computer device 10 also automatically sends instructions to other related electrical equipment (such as lighting devices) in the No. 1 compartment 21 so that the other related electrical equipment in the No. 1 compartment 21 prepares for the aging test of the display screen in the compartment 21.

[0030] In some embodiments, the display can operably display a human-machine interface having multiple operation controls corresponding to multiple compartments 21 respectively. When the operator wants to perform an aging test on the display screen in a certain compartment 21, he / she can operate the corresponding operation control. The computer device 10 then sends screen data to the graphics generator 31 on the trolley 30 in the compartment 21 and controls the relevant electrical equipment in the compartment 21 to prepare for work.

[0031] In some embodiments, the first identifier 32 is a serial port device networking server, which has a second preset IP address, and the second preset IP address constitutes the aforementioned first identifier information. The serial port device networking server can be purchased from Shandong Youren IoT Co., Ltd., and its model can be USR-TCP232-302 (commonly known as "Youren USR-TCP232-302 module"), USR-TCP232-304, USR-TCP232-306, USR-TCP232-410s, or USR-TCP232-test.

[0032] The IP address of the serial port device networking server, i.e., the second preset IP address, can be pre-configured and fixed by the operator. After the operator moves a trolley 30 into the corresponding compartment 21, the power is connected to the serial port device networking server and the graphics generator 31 on the trolley 30. After the serial port device networking server is powered on, it can create a TCP / IP network connection to attempt to access the services started by the computer device 10, and can obtain the second identification information representing the identity of the compartment 21 from the second identifier 22 of the compartment 21. After the listening port of the computer device 10 obtains the communication information of the serial port device networking server that is currently requesting a connection, it establishes communication with the serial port device networking server and resolves the IP address of the serial port device networking server, i.e., the aforementioned second preset IP address. Based on the second preset IP address, the identity of the trolley 30 is determined. Then, based on the association relationship with the first identification information and the second preset IP address, the IP addresses of each graphics generator 31 in the compartment 21 are further determined, and then screen data is sent to these graphics generators 31. Furthermore, during this process, the serial port device network server, which acts as the first identifier 32, sends the second identifier information of the second identifier 22 to the computer device 10, so that the computer device 10 knows the current compartment 21 of the trolley 30 and can perform relevant control on the compartment 21.

[0033] In some embodiments, the second identifier 22 is a relay with a DIP switch function, and the DIP switch value constitutes the aforementioned second identifier information. This relay can be purchased from Beijing Juying Aoxiang Electronics Co., Ltd., and the model can be DAM0404D or DAM0606. For example, the four second identifiers 22 (DAM0404D relays) in the four compartments 21 of the aging test furnace 20 can be DIP-switched to 1, 2, 3, and 4 respectively. The DIP switch values ​​1 to 4 correspond to the aforementioned second identifier information of the four compartments 21. When the computer device 10 obtains the first identifier information 192.168.5.230 and the second identifier information 3 from a certain first identifier 32, it indicates that the trolley 30 with IP address 192.168.5.230 is in compartment 3 21. In some embodiments, other electrical devices electrically connected to the relay are provided in the compartment 21, and the power supply to these other electrical devices is controlled by the relay.
