[0046] Other advantages and effects of the present application can be easily understood by those skilled in the art from the above description. The present application can also be implemented or applied in other different embodiments, and the details in the description can be modified or changed in various ways without departing from the spirit of the present application.

The shape, number and ratio of the components when actually implemented can be arbitrarily changed, and the layout of the components can be more complex.

[0048] Some LED modules of switches are relatively complex and include multiple flicker modes. Different flicker modes express different information. For example, some flicker modes are as follows: 100 ms or other values are taken as a flicker unit, four flicker units are taken as a flicker period, one flicker unit is bright and the other flicker units are dark in a flicker period, which represents that the working rate of the current switch is 100 m, two flicker units are bright and the other flicker units are dark in a flicker period, which represents that the working rate of the current switch is 1000 m, and three flicker units are bright and the other flicker units are dark in a flicker period, which represents that the working rate of the current switch is 2500 m.

[0049] Different flicker modes can also be flexibly configured according to user preferences. For example, some flicker modes are as follows: 100 ms or other values are taken as a flicker unit, any number of flicker units can be configured as a flicker period, the number of bright flicker units and the number of dark flicker units in a flicker period can be configured, and finally the LED flickers according to the configuration.

[0050] A common and general flicker mode is as follows: 100 ms or other values are taken as a flicker unit, two flicker units are taken as a flicker period, one flicker unit is bright and the other flicker unit is dark.

[0051] The user can configure the information conveyed by the blinking to be either half-duplex or full-duplex at the moment, or to indicate that there is a data packet being sent or received at the moment, or to indicate the working rate.

[0052] The application provides an LED verification device, method and electronic equipment, and solves the problem that it is difficult to determine whether the current blinking mode of an LED is correct in the prior art, thereby affecting the working of a switch.

[0053] The technical solutions in the embodiments of the application will be described in detail below with reference to the drawings in the embodiments of the application.

[0054] Please refer to Figure 1 As shown in the figure, the LED verification device 100 includes an LED identification module 110, an LED blinking waiting module 120, an LED blinking mode checking module 130 and an LED state output module 140. The LED identification module 110 is in communication connection with the LED, identifies the current state information of the LED based on the configuration information preset by the LED and the level information output by the LED, the LED blinking waiting module 120 is in communication connection with the LED identification module 110, waits for the occurrence of blinking based on the current state information of the LED, if the occurrence of blinking is waited for, records the start time of the current state of the LED and the blinking occurrence time based on the current state information of the LED, otherwise, outputs the current state information of the LED to the LED state output module, the blinking of the LED is the jump of the LED from the current state to the opposite state, the blinking occurrence time of the LED is the time when the LED jumps from the current state to the opposite state, the LED blinking mode checking module 130 is in communication connection with the LED blinking waiting module 120, determines the blinking mode of the LED based on the start time of the current state of the LED and the blinking occurrence time, verifies whether the blinking mode of the LED is consistent with the preset blinking mode of the LED based on the configuration parameters of the preset blinking mode of the LED, and the LED state output module 140 is used for outputting the current state of the LED based on the current state information of the LED output by the LED blinking waiting module 120.

[0055] Specifically, the LED verification device provided by the embodiment of the present application is a verification device for LED design, which takes the output of LED design as input, analyzes the output of LED design to obtain the current state of the output of LED design, and then judges whether the current output of LED design meets the expectation according to the analyzed state of the output of LED design, so as to help find the output error of the current LED design.

[0056] As shown in Figure 2 In an embodiment of the present application, the LED identification module 110 includes an LED expected output unit 111 and an LED state judgment unit 112; the LED expected output unit 111 obtains the state information of the LED preset based on the configuration information of the LED preset; and the LED state judgment unit 112 determines the current state information of the LED based on the state information of the LED preset and the level information of the LED output.

[0057] Specifically, the LED identification module 110 outputs the bright or dark information of the current LED according to the polarity of the LED design output configured by the user, and the polarity of the LED design output configured by the user indicates whether the low level of the current LED design output represents the LED bright, the high level represents the LED dark, or the high level of the LED output represents the LED bright, and the low level represents the LED dark.

[0058] As shown in Figure 2 In an embodiment of the present application, the LED flicker waiting module 120 includes an LED first recording unit 121, an LED flicker waiting judgment unit 122 and an LED second recording unit 123; the LED first recording unit 121 is used for recording the current state information of the LED and the starting time of the current state of the LED; the LED flicker waiting judgment unit 122 waits for the occurrence of the flicker based on the current state information of the LED, records the flicker waiting time of the LED from the starting time of the current state of the LED, and judges whether the flicker waiting time of the LED exceeds the waiting time threshold, if not, obtains the flicker occurrence time of the LED, otherwise outputs the current state information of the LED to the LED state output module; wherein the flicker waiting time of the LED is any time period from the starting time of the current state of the LED to the flicker occurrence time; and the LED second recording unit 123 is used for recording the state information of the opposite state of the LED and the flicker occurrence time of the LED.

[0059] Specifically, the LED flicker waiting module 120 waits for the jump of the LED according to the LED bright or dark information output by the current LED design, such as waiting for the LED to be dark if the current LED is bright, and vice versa. If the jump is waited for before the set time threshold, two sampling times are output, one of which is the time when the jump is waited for, and the other is the time when the jump occurs, and the two sampling times are marked as fir_time and sec_time, and the two sampling times are input to the LED flicker mode checking module 130 for jump time checking. If the jump is not waited for before the set time threshold, the LED state output module is entered to judge whether the LED outputs bright or dark. It should be noted that the jump of the LED is also the flicker of the LED.

[0060] Specifically, the start time of the current state of the LED is the waiting flicker time of the LED, that is, the time when the jump is waited for, and the flicker occurrence time of the LED is the time when the jump occurs.

[0061] Please refer to Figure 2 As shown in the figure, in an embodiment of the present application, the LED state output module 140 includes an LED state output unit 141; the LED state output unit 141 outputs the current state of the LED based on the LED current state information output by the LED flicker waiting judgment unit 122.

[0062] Specifically, the LED state output module 140 outputs the LED state as bright or dark according to the bright or dark information output by the LED, and checks whether there is illegal jump (illegal flicker) according to the jump counter. When the number of jumps counted exceeds the allowed value configured by the user, an error is reported.

[0063] Please refer to Figure 2 As shown in the figure, in an embodiment of the present application, the LED flicker mode checking module 130 includes an LED flicker unit time length acquisition unit 131 and an LED error judgment unit 132; the LED flicker unit time length acquisition unit 131 acquires the LED flicker time based on the start time of the current state of the LED and the flicker occurrence time of the LED; the LED error judgment unit 132 obtains the error rate of the LED flicker time based on the configuration parameters of the LED preset flicker mode and the LED flicker time, compares the error rate with the preset error rate, and verifies whether the current flicker mode of the LED is consistent with the preset flicker mode of the LED; wherein the error rate is determined according to the relationship between the expected flicker time of the LED and the flicker time of the LED.

[0064] Specifically, the error rate is a ratio of an absolute value of a difference between the expected flicker time of the LED and the flicker time of the LED and the expected flicker time of the LED.

[0065] Specifically, the LED flicker mode checking module 130 checks according to the input LED flicker mode configuration parameters, the LED flicker mode configuration parameters including a time length of one flicker unit in the LED flicker mode, a number of the flicker units in one flicker cycle in the LED flicker mode, and a bright or dark condition of each flicker unit in one flicker cycle, where the number 1 represents LED bright and the number 0 represents LED dark. According to the above LED flicker mode configuration parameters, the time and the number of LED bright in one flicker cycle can be obtained, and the time and the number of LED dark in one flicker cycle can be obtained.

[0066] The absolute value of the difference between the two sampling times fir_time and sec_time output by the LED flicker waiting module 120 is the output flicker time. The output flicker time and the bright time or the dark time obtained from the LED flicker mode configuration parameters are compared to see whether it is less than the receivable error rate. If it is less than or equal to the receivable error rate, the check passes; if it is greater than the receivable error rate, the check fails. Only when the check passes in the flicker cycle of one LED flicker mode, the error indication signal err_en is output as 0; otherwise, the error indication signal err_en is output as 1.

[0067] Referring to Figure 3 As shown in the figure, in an embodiment of the present application, the LED verification device 100 includes a plurality of LED flicker mode checking modules 130 (for example, LED flicker mode checking module 1, LED flicker mode checking module 2, …, LED flicker mode checking module x); each of the LED flicker mode checking modules 130 checks a preset flicker mode; and each of the LED flicker mode checking modules 130 performs the checking work in parallel or in series.

[0068] Referring to Figure 3 As shown in the figure, in an embodiment of the present application, the LED verification device further includes an LED flicker mode judgment module 150; the LED flicker mode judgment module 150 is used to judge whether only one checking result passes in the checking results of the plurality of LED flicker mode checking modules 130. If yes, the checking ends; if not, the LED recognition module is returned to be recognized again.

[0069] Specifically, the LED verification device according to the present application embodiment includes a plurality of LED flicker mode checking modules 130, each of which is configured to check a preset LED flicker mode. The user configures the configuration parameters of each LED flicker mode to the values required by the corresponding LED flicker mode. The LED flicker mode judgment module 150 performs the checking work in parallel on all the flicker modes, and the length of time for one checking is the longest flicker period in all the flicker modes. Only when one of the LED flicker modes passes the checking, the checking can be ended, and the LED flicker output module outputs the corresponding LED flicker mode state signal.

[0070] After the LED flicker checking is completed, the LED flicker judgment module 150 enters the LED flicker waiting module to continue waiting for the next flicker, and performs the time checking on the next flicker until all the flicker modes have completed the checking of one flicker period.

[0071] Please refer to Figure 3 As shown in the figure, in the present application embodiment, the LED verification device 100 further includes an LED flicker output module 160, which is configured to output the preset LED flicker mode corresponding to the LED flicker mode checking module 130 whose checking result is passed, as the LED flicker mode.

[0072] Specifically, the LED flicker output module 160 outputs the preset LED flicker mode corresponding to the LED flicker mode checking module 130 whose checking result is passed, as the LED flicker mode. After the LED state output module 140 and the LED flicker output module 160 output the LED bright or flicker or jump mode, they return to the LED recognition module 110 to perform the judgment and output of the next LED bright or flicker or jump mode. The LED state output module 140 and the LED flicker output module 160 output the LED bright or flicker or jump mode, which is compared with the LED bright or flicker or jump mode designed to be output by the LED. If they are the same, the checking is passed, otherwise, the checking fails. The LED verification device according to the present application embodiment can support multiple LED sequence checking, such as LED bright first, then flicker, and then dark. At this time, the LED state output module 110 and the LED flicker output module 160 of the LED verification device according to the present application embodiment will output the LED bright, LED flicker, and LED dark sequence in turn.

[0073] The following will be described in detail Figures 4 to 7 The modules in the LED verification device according to the present application embodiment will be described in detail, so as to help the skilled in the art to understand the principle of the LED verification device according to the present application embodiment.

[0074] Referring to Figure 4 As shown in the block diagram of the LED identification module 110 according to an embodiment of the present application, since the external LED diode can be connected to the cathode or the anode, when the external LED diode is connected to the cathode, the LED output low level will light the external LED diode; when the external LED diode is connected to the anode, the LED output high level will light the external LED diode. The polarity configuration of the user input configuration LED design polarity indicates whether the LED design output low level represents LED bright high level represents LED dark, or the LED output high level represents LED bright low level represents LED dark. The LED bright expected output and the LED dark expected output module determines whether the LED bright should output high level or low level according to the polarity configuration, and then compares the high or low level of the LED design output, to obtain the current LED bright state or dark state of the LED design output.

[0075] Referring to Figure 5 As shown in the block diagram of the LED identification module 110 according to an embodiment of the present application, since the external LED diode can be connected to the cathode or the anode, when the external LED diode is connected to the cathode, the LED output low level will light the external LED diode; when the external LED diode is connected to the anode, the LED output high level will light the external LED diode. The polarity configuration of the user input configuration LED design polarity indicates whether the LED design output low level represents LED bright high level represents LED dark, or the LED output high level represents LED bright low level represents LED dark. The LED bright expected output and the LED dark expected output module determines whether the LED bright should output high level or low level according to the polarity configuration, and then compares the high or low level of the LED design output, to obtain the current LED bright state or dark state of the LED design output.

[0076] The signal time_cnt in the waiting time counting module represents the current waiting time count, which is increased by one at each counting unit, while determining whether it is greater than the configured waiting time timeout threshold. If the current waiting time count is greater than the timeout threshold, a timeout occurs. The value of the configured waiting time timeout threshold needs to be greater than the maximum LED flashing period in the LED design.

[0077] If the LED flashes are waited for when time_cnt is less than or equal to the waiting time timeout threshold, the LED flashing counter is increased by one, and the current time is recorded. The two recorded time markers are fir_time and sec_time, the values of which can be sampled by the $time() function. When both fir_time and sec_time are non-zero, fir_time and sec_time are input to a plurality of LED flashing mode checking modules 130 for jump time checking; if one of fir_time and sec_time is zero, the value of the minimum of fir_time and sec_time is refreshed as the current time after waiting for the LED flashing again.

[0078] Specifically, fir_time and sec_time are used to record time, for example, the first sampling to a time time0, whether to use fir_time or sec_time to record depends on the relative size of fir_time and sec_time, the initial value of fir_time and sec_time is 0, which does not meet fir_time<sec_time, so sec_time=time0; the second sampling to a time time1, at this time fir_time is 0, sec_time is time0, which meets fir_time<sec_time, so fir_time is time1, sec_time is still time0. Then when calculating sample_blink_time, the smaller one of fir_time and sec_time will be refreshed to 0, in the above example, sec_time will be refreshed to 0, and fir_time continues to be time1. Then the third sampling to a time time2, fir_time is time1, sec_time is 0, which does not meet fir_time<sec_time, so sec_time=time2. That is, in the present application, the two variables fir_time and sec_time are used to sample time, the used time that is relatively early is eliminated by refreshing to 0 first and then refreshing to the sampling time.

[0079] If the timeout occurs but the LED does not flash, it means that the current LED does not flash, and is in a constant bright or dark state, and the LED state output module 140 outputs the LED bright state or dark state.

[0080] The LED flashing mode judgment module 150 will judge whether there is only one flashing mode in the multiple or one LED flashing mode, and after checking, it will exit the loop and enter the LED flashing output module 160 to output the flashing mode state that passes the check, otherwise it will continue to enter the LED flashing waiting module 120 to continue the next round of LED flashing waiting and time checking until the condition of exiting the loop in the LED flashing mode judgment module 150 is met.

[0081] Please refer to Figure 6The diagram shows a block diagram of the LED blinking mode checking module according to an embodiment of the present invention. The checking unit is one LED blinking cycle of the current switching mode. The checking is performed according to the configuration parameters of the input LED switching mode. The configuration parameters of the LED blinking mode are: the duration of one blinking unit in the LED blinking mode, the number of blinking units in one blinking cycle of the LED blinking mode, and the brightness or darkness of each blinking unit in one blinking cycle. The number 1 can represent the LED being bright and the number 0 can represent the LED being dark.

[0082] Based on the configuration parameters of the LED blinking mode described above, the duration and number of times the LED is on, and the duration and number of times the LED is off, can be obtained within one blink cycle. The LED blinking waiting module 120 outputs two sampling times, fir_time and sec_time. The absolute value of the difference between the two sampling times is the output blinking time. This output blinking time is compared with the on or off time obtained from the LED blinking mode configuration parameters to see if it is less than the acceptable error rate. If it is less than or equal to the acceptable error rate, the check passes; if it is greater than the acceptable error rate, the check fails.

[0083] like Figure 7 As shown, based on the two sampling times fir_time and sec_time output by the LED blinking wait module 120, the output blinking time is denoted as sample_blink_time, and the LED blink count counter blink_cnt is incremented. The output blinking time sample_blink_time and the expected blinking time exp_blink_time obtained from the LED blinking mode configuration parameters are used to calculate the error rate err_rate. This rate is then compared with the configured acceptable error rate exp_err_rate. If it is less than or equal to the configured error rate, the check passes, and the check output indicator signal err_en is set to 0; if it is greater than the configured error rate, the check fails, and the check output indicator signal err_en is set to 1. The configured acceptable error rate exp_err_rate should be determined by the current LED architecture scheme to be an appropriate error rate.

[0084] Please see Figure 7 The diagram shown illustrates the process by which the LED blinking mode determination module 150 checks multiple LED blinking mode checking modules 130 according to an embodiment of the present invention. Multiple LED blinking mode checking modules 130 are instantiated based on the number of existing LED blinking modes, with each module corresponding to a preset LED blinking mode. Users configure the parameters for each LED blinking mode to the values ​​required for that mode.

[0085] The LED flicker mode judgment module 150 checks all the flicker modes in parallel, and the duration of one check should be the longest flicker period among all the flicker modes. Only when one kind of LED flicker mode passes the check, the flag signal chk_end of the check end is 1, the check is ended, and the corresponding LED flicker mode state signal is output to the LED flicker output module 160. The output error indication signal err_en in the LED flicker mode check module 130 corresponding to the LED flicker mode that passes the check is 0, and the output error indication signal err_en in the LED flicker mode check module 130 corresponding to the LED flicker mode that fails the check is 1. After one LED flicker check is completed, the LED flicker mode judgment module 150 enters the LED flicker waiting module 120 to continue to wait for the next jump, and the time check is performed on the next flicker until all the flicker modes have completed the check of one flicker period.

[0086] Among the various LED flicker modes currently existing, there may be some LED flicker modes that have the same flicker. The LED verification device described in the embodiment of the present application requires that after the flicker periods of all the LED flicker modes are checked, only one kind of LED flicker mode passes the check, and then the check is ended, and the corresponding LED flicker mode state signal is output to the LED flicker output module 160. This requires that the user cannot input two LED flicker modes that have the same jump. Or when the flicker of the various LED flicker modes cannot be guaranteed to be different, the LED verification device needs to be informed in advance that when all the flicker modes pass the check, which flicker mode is selected to be output to the LED flicker output module 160 for flicker state output.

[0088] Step S1, identifying the current state information of the LED based on the configuration information of the LED and the level information output by the LED;

[0089] Step S2, waiting for the occurrence of flicker based on the current state information of the LED.

Otherwise, outputting the current state information of the LED to the LED state output module. The flicker of the LED is the jump of the LED from the current state to the opposite state, and the occurrence time of the flicker of the LED is the time when the LED jumps from the current state to the opposite state;

[0090] Step S3, determining the flicker mode of the LED based on the starting moment and the flicker occurrence moment of the current state of the LED; verifying whether the flicker mode of the LED is consistent with the preset flicker mode of the LED based on the configuration parameter of the preset flicker mode of the LED.
