Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a method for detecting a flash leakage of a flash burst lamp according to an embodiment of the present invention, where the method is applicable to a situation where a flash leakage of a flash burst lamp is detected before the flash burst lamp leaves a factory.

As shown in fig. 1, the method for detecting flash leakage of the flashing lamp specifically comprises the following steps:

s101, determining initial coding data, and triggering a flashing light to flash according to the initial coding data.

In the embodiment of the invention, because the design circuit and the flashing characteristics of the flashing light have great influence on the duration and the brightness of the flashing light, the design circuit and the flashing characteristics of the flashing light to be detected at present need to be considered when the initial coding data for controlling the flashing light to carry out flashing is determined. Optionally, according to the design circuit and the flashing characteristics of the flashing light, a flashing duration parameter t and a brightness parameter k are preset. Illustratively, the determined initial encoding data is "1001001000100001", where the code 1 indicates that the flashing light is controlled to perform effective flashing (i.e., the duration of the flashing is greater than or equal to t, and the brightness is greater than or equal to k), and the code 0 indicates that the flashing light is controlled to perform ineffective flashing (i.e., the time interval of the flashing is less than t, and the brightness is less than k). It should be noted that the initial encoding data may be input in advance, and the encoding bit number may be set according to the actual detection requirement.

Furthermore, after the initial coding data is obtained, a flashing light can be triggered to flash according to the initial coding data. Specifically, only need with initial coding data conversion is to explode and dodges trigger signal cluster, and based on explode and dodge trigger signal cluster control explode the flashing lamp and explode and dodge, for example, can adopt to explode and dodge the flashing trigger signal value in the flashing trigger signal cluster and control exploding the flashing lamp. For example, the initial encoding data may be converted into a PWM pulse signal, where the code 1 corresponds to a high level, the code 0 corresponds to a low level, and the pulse width corresponds to a flashing duration, so that the flashing light may be triggered to flash by the high level of the PWM pulse signal.

S102, monitoring an optical signal generated in the flashing process of the flashing lamp, and coding the optical signal to obtain target coded data.

In an optional implementation manner, the brightness and the duration of an optical signal generated in the flashing process of the flashing light are detected, and encoding is performed according to whether the brightness and the duration of the optical signal meet preset conditions, so as to obtain target encoded data. Illustratively, if the brightness of the light signal is greater than or equal to k and the duration is greater than or equal to t, the light signal is encoded as 1 (i.e., an active burst); if the brightness of the light signal is less than k or the duration is less than t, the light signal is encoded as 0 (i.e., an invalid flash). Therefore, the target coding data which represents the actual flashing process of the flashing lamp is obtained, namely, the actual flashing condition of the flashing lamp is restored into the corresponding coding data, so that the subsequent flashing leakage detection is facilitated, wherein the times of effective flashing and the times of ineffective flashing of the flashing lamp in the actual flashing process are recorded in the target coding data. It should be noted here that the target encoded data and the initial encoded data have the same number of bits.

S103, comparing the initial coding data with the target coding data, and determining whether the flashing light has flashing leakage according to the comparison result.

Optionally, the initial coded data and the target coded data are compared, that is, the initial coded data and the target coded data are compared according to bits, if the initial coded data and the target coded data are the same, it is determined that the flashing leakage does not exist in the flashing process of the flashing lamp, if the data on one or more coded bits are different, it is determined that the flashing leakage exists, and according to the number and the position of the coded bits with different values, the number and the position of the flashing leakage can also be determined. Illustratively, the initial encoding data is "1001001000100001", the target encoding data is "1000001000100001", and the comparison shows that only the fourth encoding bit value is different, so that there is one flash leakage.

In the embodiment of the invention, the initial coding data for controlling the flashing of the flashing light is compared with the obtained target coding data for representing the actual flashing process of the flashing light, and whether the flashing light leaks or not is determined according to the comparison result. Only need compare initial coding data and target coding data, can confirm whether to have the flashing leakage of flashing lamp, compare in through the mode of artifical observation photo in order to confirm whether to leak the flashing, realized the automation that the flashing leakage of flashing lamp detected, be favorable to promoting efficiency and the accuracy that the flashing leakage of flashing lamp detected.

Example two

Fig. 2 is a schematic flow chart of the method for detecting a missing flash of a flashing lamp according to an embodiment of the present invention, and in the second embodiment, optimization is performed on the basis of the first embodiment, referring to fig. 2, the method includes:

s201, determining initial coding data, and triggering a flashing light to flash according to the initial coding data.

In the embodiment of the invention, in order to ensure the accuracy of the detection of the flash leakage of the flashing lamp, the initial coding data is divided into three parts, specifically comprising a start code pattern, a test code pattern and an end code pattern. In the embodiment of the present invention, the same number of coding bits of the start code pattern, the test code pattern, and the end code pattern is taken as an example to explain, for example, all are 16 bits.

The initial code type is used for indicating the coding data that begin the hourglass detection of dodging, in order to guarantee follow-up in time to leak the detection of dodging, need guarantee that the initial code value of initial code type can trigger the flashing light carries out effective flashing, also regards as the sign that begins the hourglass detection of dodging with exploding the flashing for the first time. Illustratively, the start pattern is a set of data beginning with code 1, such as "1010010001000010," whereby flash loss detection can be initiated sequentially after a flash burst is first detected. It should be noted that, if the first code value of the start code pattern cannot trigger the flashing light to perform effective flashing (for example, the first code value is 0), the start code pattern is exemplarily "0010010001000010", and if the first flashing is detected as the sign for starting the detection of the flashing leakage, the time for detecting the flashing leakage is inevitably delayed, and the detection result is inaccurate. The test pattern is encoded data actually used to test whether the strobe light is missed. An end pattern, such as "1000010001001010," is used to indicate the encoded data that ends a complete missed flash detection.

Further, the test pattern can be divided into a first test pattern, a second test pattern and a third test pattern based on the designated parameters, and optionally, based on the frequency of triggering the flashing light to flash, the test pattern is divided into a high-frequency test pattern (i.e., the first test pattern), a medium-frequency test pattern (i.e., the second test pattern) and a low-frequency test pattern (i.e., the third test pattern). For example, two burst frequency thresholds (e.g., a first frequency threshold and a second frequency threshold) are preset, and a test pattern with a burst frequency smaller than the first frequency threshold may be used as a low-frequency test pattern, a test pattern with a burst frequency between the first frequency threshold and the second frequency threshold may be used as an intermediate-frequency test pattern, and a test pattern with a burst frequency greater than the second frequency threshold may be used as a high-frequency test pattern. The high-frequency test code pattern, for example "0101010101010101", is used for testing the performance of the flashing light during high-frequency flashing, and the high-frequency test code pattern is used for carrying out a flashing leakage test, so that the performance of the flashing light during the fastest flashing is simulated in the environment with large traffic flow (such as commuting peak), specifically, whether the continuous quick charging and discharging of the capacitor in the hardware single board of the flashing light are problematic is mainly verified through the high-frequency test code pattern, namely, the performance of the capacitor charging is verified. The intermediate frequency test pattern, such as '0001000100010001', is used for testing the performance of the flashing lamp in the flashing process according to the intermediate frequency, and the intermediate frequency test pattern is used for carrying out the flash leakage test, so that the performance of the flashing lamp in the flashing process in the proper traffic flow environment is simulated. The low-frequency test pattern, such as '0000000100000001', is used for testing the performance of the flashing light in the flashing process according to the low frequency, and the low-frequency test pattern is used for carrying out the flashing leakage test, so that the flashing performance of the flashing light under the environment with small traffic flow is simulated. It should be noted that the intermediate frequency test pattern and the low frequency test pattern are both used to verify the reliability and trigger stability of the design of the burst flashing light circuit.

Further, since the test pattern includes patterns of three different frequencies, there are three corresponding initial encoded data of different trigger frequencies. Specifically, if the test pattern is a high-frequency test pattern (i.e., a first test pattern), the initial encoded data is high-frequency encoded data including a start pattern, a high-frequency test pattern, and an end pattern; if the test pattern is an intermediate frequency test pattern (i.e., a second test pattern), the initial encoded data is intermediate frequency encoded data including a start pattern, an intermediate frequency test pattern, and an end pattern; if the test pattern is a low-frequency test pattern (i.e., a third test pattern), the initial encoded data is low-frequency encoded data including a start pattern, a low-frequency test pattern, and an end pattern.

In actual detection, optionally, after the high-frequency coded data is used for completing one detection, the intermediate-frequency coded data or the low-frequency coded data is used for detection, and the specific detection times and the coded data used for each detection can be preset. It should be noted here that, because the flashing interval of the flashing light is short, the testing period is long, and if the high-frequency coded data is used for detection, the flashing light is easy to be damaged due to excessive heat accumulation, so that the coded data with different frequencies are used for detection in the embodiment of the present invention, and the coded data with different frequencies can simulate the actual traffic flow condition, so that the maximum problem of the flashing light can be exposed in the shortest time, the flashing times can be reduced, and the light pollution can be reduced.

S202, detecting the brightness and the duration of an optical signal generated in the flashing process of the flashing lamp, and coding according to whether the brightness and the duration of the optical signal meet preset conditions to obtain target coded data.

Illustratively, if the brightness of the light signal is greater than or equal to k and the duration is greater than or equal to t, the light signal is encoded as 1 (i.e., an active burst); if the brightness of the light signal is less than k or the duration is less than t, the light signal is encoded as 0 (i.e., an invalid burst).

Specifically, since the initial encoded data is composed of a start pattern + a high frequency test pattern or an intermediate frequency test pattern or a low frequency test pattern + an end pattern, each pattern includes 16 bits of encoded data. Therefore, for the convenience of subsequent comparison, after the detected optical signal is encoded, the obtained encoded data is grouped into one encoding group every 16 bits, and thus, the finally obtained target encoded data includes the first encoding group, the second encoding group, and the third encoding group. Moreover, the first code group corresponds to the start code pattern, the second code group corresponds to the test code pattern, and the third code group corresponds to the end code pattern. It should be noted that, no matter whether the encoding bits of the start code pattern, the test code pattern, and the end code pattern in the initial encoding data are the same, it is only necessary to ensure that the encoding bits of the first encoding group and the start code pattern are the same, the encoding bits of the second encoding group and the test code pattern are the same, and the encoding bits of the third encoding group and the end code pattern are the same.

S203, determining whether the start code pattern is the same as the first code group, if not, performing S204, and if so, performing S205.

Since the start code pattern and the first code group are both arrays of 0 and 1, in order to improve the comparison efficiency, the start code pattern and the first code group are compared bit by bit, and whether the start code pattern is the same as the first code group is determined according to the comparison result. As an optional implementation manner, the start code pattern and the first code group are subjected to a logical operation process, and whether the start code pattern is the same as the first code group is determined according to an operation result. For example, the start code pattern and the first code group are subjected to xor operation, and the principle of xor operation is that the two code bits have the same value, and the result is 0, and the result is 1, so that whether the start code pattern and the first code group are the same or not can be determined only according to the number of 1 included in the xor operation result, for example, if there is no 1 in the operation result, it is determined that the two are the same, and otherwise, they are different.

It should be noted that, when determining whether the start code pattern and the first code group are the same, other feasible operation manners may also be adopted, such as performing an exclusive nor operation, and according to the exclusive nor operation principle (that is, the values on the two code bits are the same, the operation result is 1, otherwise, the operation result is 0), whether the start code pattern and the first code group are the same may be determined based on the number of 0 in the operation result, for example, if there is no 0 in the operation result, it is determined that the two are the same, otherwise, they are different.

And S204, uploading the judgment result to a management system, and indicating that the flash leakage detection is continued by adopting new initial coding data.

In the embodiment of the invention, if the initial code type is different from the first coding group, the problem of the initial code type test is shown, namely the problem occurs just after the flashing of the flashing lamp begins, so that the internal circuit of the flashing lamp has a larger problem inevitably, the flashing is unstable, the judgment result needs to be uploaded to a management system, and the management system outputs a warning signal so as to inform related technicians to carry out professional detection on the flashing lamp to determine the specific fault and maintain the flashing lamp. In addition to this, it may also be instructed to continue with the missing flash detection with the new initial encoded data.

S205, judging whether the test code pattern is the same as the second coding group, and determining whether the flashing light has flash leakage according to the judgment result.

Optionally, comparing whether the test pattern is the same as the second code group, comparing the test pattern with the second code group according to bits, and determining whether the test pattern is the same as the second code group according to a comparison result. As an optional implementation manner, the test pattern and the second coding group are subjected to logic operation, for example, the test pattern and the second coding group are subjected to xor operation, and whether the test pattern and the second coding group are the same is determined according to the operation result, that is, according to the number of 1 in the xor operation result, whether the test pattern and the second coding group are the same can be determined. If the operation result does not contain 1, the two are the same, and the flash lamp does not have flash leakage; if the operation result has 1, the two are different, and the encoding bit corresponding to the value 1 in the operation result has flash leakage. In addition, the number, the flashing leakage rate and the flashing leakage position of the current detection can be determined according to the number and the position of the 1 in the operation result. Furthermore, after the number of times of flash leakage, the flash leakage rate and the flash leakage position are obtained, the flash leakage times, the flash leakage rate and the flash leakage position can be uploaded to a management system and processed by the management system.

In addition, it is also possible to determine whether the test pattern is the same as the second code group, or to use other feasible operation manners, such as performing an exclusive nor operation, and determine whether the test pattern is the same as the second code group according to the number of 0 in the operation result, for example, if there is no 0 in the operation result, the test pattern is the same as the second code group, otherwise, the test pattern is different from the second code group, and further, the number of times of flash leakage, the rate of flash leakage, the position of flash leakage, and the like can be determined according to the number and the position of 0.

In the embodiment of the invention, the coded data with different frequencies are adopted to simulate the actual traffic flow environment and carry out the leakage flash detection, so that the problems of the flash lamp can be detected in the shortest time, and the flash times and the light pollution are reduced; and carry out the uniformity comparison through the first coding group, the second coding group that obtain with the code respectively with initial code pattern, test code pattern, be favorable to promoting the hourglass and dodge statistical efficiency, and can accurately obtain whether the flashing lamp takes place to leak and dodge.
