Description

Technical Field

[0001] This invention relates to the field of determining the usage time of LED display modules, specifically a method for correcting the usage time of multiple LED display modules under a single receiver card. Background Technology

[0002] An LED display screen typically consists of multiple LED display modules and a receiver card. These modules are interconnected and electrically connected to the receiver card to form a single display. The receiver card sends display signals to the LED display modules to display the corresponding content. In an LED display screen, when one or more LED display modules need to be replaced due to damage, or when a module is repaired and reinstalled after a malfunction, there is a period of offline time between the new and reinstalled modules. This period is not recorded, requiring manual verification of the LED module's usage time. Usage time refers to the length of time from the initial setup of the LED module to the current time. Each LED display module has its own corresponding usage time, and the probability of malfunction or damage varies among modules. Therefore, after a period of use, each LED display module needs to be recalibrated to its correct usage time. Current technology uses manual verification, which is time-consuming and labor-intensive. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a method for correcting the usage time of multiple LED display modules under a single receiver card, which can solve the problems described in the background art.

[0004] The technical solution to achieve the objective of this invention is as follows: A method for correcting the usage time of multiple LED display modules under a single receiver card includes the following steps:

[0005] Step 1: Before the LED display module is connected to the receiving card, the usage time recorded locally by the LED display module is initialized to 0. After the LED display module is connected to the receiving card, Step 2 is executed.

[0006] Step 2: After at least two LED display modules have been connected to the receiving card, the receiving card collects the usage time of the LED display modules connected to the receiving card at preset collection time intervals and stores it locally on the receiving card.

[0007] Step 3: Determine whether the usage time of the LED display module detected by the receiving card is abnormal, and mark the LED display modules with abnormal usage time as abnormal LED display modules, and the LED display modules with normal usage time as normal LED display modules.

[0008] For the currently abnormal LED display module, the usage time of the current abnormal LED display module is updated based on the usage time of the normal LED display module and the preset collection time interval, thereby completing the correction of the LED display module usage time.

[0009] Furthermore, in step 1, the LED display module's memory records the usage time, meaning that each LED display module has its own memory to store its own usage time.

[0010] Furthermore, in step 2, the receiving card is also equipped with memory, and the collected usage time is stored in the memory.

[0011] Furthermore, in step 3, the specific implementation process of updating the usage time of the current abnormal LED display module based on the usage time of the normal LED display module and the preset collection time interval includes:

[0012] The usage duration of the currently abnormal LED display module is compared with that of all normal LED display modules collected at the same time T. If N normal LED display modules have the same usage duration as the usage duration recorded at the previous collection time T, and N≥M, then the usage duration of the currently abnormal LED display module is determined to be abnormal, where M is a preset threshold, and M≥2.

[0013] After determining that the usage time of the current abnormal LED display module is abnormal, the usage time stored in the receiver card is added to the preset collection time interval corresponding to the current abnormal LED display module to obtain the current abnormal LED display module's usage time, thereby successfully correcting the current abnormal LED display module's usage time. Simultaneously, the usage time of the current abnormal LED display module stored in the receiver card is updated.

[0014] Furthermore, the same time T is a completely consistent acquisition time, or the acquisition times of each normal LED display module are all within the allowable time error range.

[0015] Furthermore, step 3 also includes the following: if there are no N normal LED display modules whose usage time matches the usage time recorded at the previous acquisition time of time T and N≥M, then the receiving card is determined to be damaged, and the current usage time of each LED display module is stored in the receiving card.

[0016] A damaged receiver card means that the receiver card has failed to receive the usage time of the LED display module, or has lost the ability to receive the usage time of the LED display module.

[0017] Furthermore, M is half the total number of all normal LED display modules.

[0018] The beneficial effects of this invention are as follows: This invention can determine whether the usage time of a current LED display module is abnormal by connecting LED display modules under the same receiving card, and it can also determine whether the receiving card is functioning correctly. Furthermore, by simply adding a preset data acquisition time interval to the usage time backed up by the receiving card, the usage time of an abnormal LED display module can be changed to the correct usage time. The operation is simple, requires no manual calibration, and saves time and effort. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the process of the present invention. Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0021] like Figure 1 As shown, a method for correcting the usage time of multiple LED display modules under a single receiver card includes the following steps:

[0022] Step 1: Before the LED display module is connected to the receiving card, the usage time recorded locally by the LED display module is initialized to 0, that is, there is no usage time. After the LED display module is connected to the receiving card, proceed to Step 2.

[0023] In this context, "LED display module accessing the receiving card" means that the LED display module and the receiving card have been successfully connected and can now communicate with each other.

[0024] In this step, the LED display module's memory records the usage time; that is, each LED display module has its own memory to store its own usage time. The usage time of each LED display module that has not yet been connected to the receiving card is initialized to 0. For LED display modules that have been connected to the receiving card, step 2 is executed. Therefore, "LED display modules not connected to the receiving card" does not mean that all LED display modules must be not connected to the receiving card, but only refers to one or more LED display modules that have not been connected to the receiving card, excluding those connected to the receiving card. For ease of display and reminder, after initialization, the usage time stored in the memory is initialized to FF, that is, FF represents that the current usage time of the LED display module is 0, meaning it has not yet been put into use.

[0025] Step 2: After at least two LED display modules have been connected to the receiving card, the receiving card collects the usage time of each LED display module connected to the receiving card at preset collection time intervals and stores it locally on the receiving card.

[0026] In this step, the receiving card is also equipped with memory. Therefore, the usage time of each LED display module that has been connected to the receiving card is collected and stored in the memory of the receiving card.

[0027] The preset acquisition time intervals for each LED display module connected to the receiving card can be the same or different (i.e., dissimilar). That is, the acquisition time intervals for each LED display module connected to the receiving card can be the same or different. It can be that all LED display modules connected to the receiving card have the same or different acquisition time intervals, or that some acquisition time intervals are the same (and the other part is different). For example, if there are three LED display modules (a, b, c) currently connected to the receiving card, the receiving card acquires the usage time of display module a every 1 minute, the usage time of display module b every 1 minute, and the usage time of display module c every 3 minutes.

[0028] Step 3: Determine whether the usage time of the LED display module collected by the receiving card is abnormal, and record the LED display module with abnormal usage time as abnormal LED display module, and the LED display module with normal usage time as normal LED display module.

[0029] For the current abnormal LED display module, the usage time of the current abnormal LED display module is compared with that of all normal LED display modules collected at the same collection time T. If there are N normal LED display modules whose usage time is consistent with the usage time recorded at the previous collection time T and N≥M, then the usage time of the current abnormal LED display module is judged to be abnormal, where M is a preset threshold and M≥2. After determining that the usage time of the current abnormal LED display module is abnormal, the usage time stored in the receiver card is added to the preset collection time interval corresponding to the current abnormal LED display module to obtain the current usage time of the abnormal LED display module, thereby successfully correcting the usage time of the current abnormal LED display module. Simultaneously, the usage time of the current abnormal LED display module stored in the receiver card is updated, that is, the time obtained by adding the backup time in the receiver card to the preset collection time interval corresponding to the current abnormal LED display module replaces the original usage time stored in the receiver card. This allows the receiver card to always store the correct usage time of the current abnormal LED display module, so that if the current abnormal LED display module malfunctions again, it can be updated to the correct usage time based on the usage time stored in the receiver card.

[0030] Since the receiving card collects the usage time of the LED display module according to a preset collection time interval, the previous collection time of time T is also the time obtained by subtracting a preset collection time interval from the current collection time T.

[0031] Here, the same time T can be a completely consistent acquisition time, meaning that the acquisition times of all normal LED display modules are exactly the same. Alternatively, it can be that the acquisition times of each normal LED display module are within the allowable time error range. For example, if the acquisition times of three normal LED display modules differ by one second, and the difference between the maximum and minimum acquisition times is two seconds, and two seconds is within the allowable time error range, then the acquisition times of these three normal LED display modules can be considered the same acquisition time T.

[0032] In an optional implementation, step 3 further includes: if none of the N normal LED display modules have a usage time consistent with the usage time recorded at the previous acquisition time T and N≥M, then the receiving card is determined to be damaged, and the current usage time of each LED display module is stored in the receiving card. Receiver card damage means that the receiving card has failed to receive the usage time of the LED display modules, or has lost the ability to receive the usage time of the LED display modules. For example, the receiving card is replaced with a new one, but the new receiving card does not read the usage time of each LED display module stored in the original receiving card, meaning the new receiving card has not stored the previous usage time of each LED display module. Another example is that the receiving card hardware or software (system) has crashed, rendering it unusable, i.e., it has lost the ability to receive the usage time of the LED display modules.

[0033] In one implementation, M is half the total number of all normal LED display modules. For example, if M is the total number of all normal LED display modules, it means that if the usage time of all normal LED display modules is consistent with the usage time recorded at the previous acquisition time T, then the usage time of the currently abnormal LED display module is determined to be abnormal.

[0034] This invention can determine whether the usage time of a current LED display module is abnormal by connecting LED display modules under the same receiving card, and can also determine whether the receiving card is functioning properly. Furthermore, by simply adding a preset data acquisition time interval to the usage time backed up by the receiving card, the usage time of an abnormal LED display module can be corrected. The operation is simple, requires no manual calibration, and saves time and effort.

Any other functionally equivalent embodiments fall within the scope of protection of the invention. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of this invention.
