Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
It is noted that the terms first, second and the like in the description and in the claims, as well as in the drawings, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or described herein.
Referring to fig. 1, an embodiment of the present invention provides a method for determining a signal lamp control scheme, including:
s1, obtaining light color information of a signal lamp, wherein the signal lamp comprises a plurality of lamp groups;
specifically, in the embodiment of the present invention, for the determination of the control scheme of the signal lamp, the determination is implemented based on the light color information of the signal lamp, the signal lamp includes a plurality of lamp groups, such as a vehicle communication lamp group and a pedestrian lamp group in the east-west-south-north direction, and correspondingly, the light color information of all the lamp groups is obtained at the same time.
S2, when the signal lamp is determined to have the light color change according to the light color information, generating signal lamp step data, wherein each signal lamp step data comprises the light color information of each lamp group and the light color change interval time when the signal lamp has the light color change;
when the light color information changes, if the obtained light color information is changed from green light to yellow light, the light color change can be judged, and the light color information (yellow light) of the signal lamp group is one of the light color information of the currently obtained signal lamp pace data.
Because the lamp color changes frequently in the control process of the signal lamp, one signal lamp step data is generated when the lamp color changes every time, and the signal lamp step data generated by sequentially changing the lamp color are the signal lamp step data of the first step, the second step \8230andthe Nth step.
For the light color change interval time, in the embodiment of the present invention, the light color change interval time is determined when the light color of the whole signal lamp changes, for example, the signal lamp step data of the first step is collected when the light color of the signal lamp changes in the east-west direction, the signal lamp step data of the second step is collected when the light color of the signal lamp changes in the north-south direction, and for two adjacent steps, the light color change interval time is the interval time of the initial time of the two steps, that is, the duration time of the previous step.
And S3, determining a signal lamp control scheme according to the comparison condition among the signal lamp step data.
In signal light control, a signal light control scheme generally involves switching of a signal light color and a lamp color maintenance time in a cycle in which, when the lamp color maintenance time reaches a predetermined time, a current lamp color is switched to a next lamp color, and the next lamp color continues for a preset time, thereby continuing to cycle by cycle. In the process, the generated signal lamp step data comprising the light color information and the light color change interval time can also reflect periodic change, so that the signal lamp step data are continuously detected, each signal lamp step data is compared, the period of the signal lamp control scheme can be accurately determined, and then after the period is determined, the light color sequence and the countdown sequence of the signal lamp control scheme can be determined according to the light color recorded by the signal lamp step data and the time point of the light color change in each lamp group. Therefore, the signal lamp control scheme is determined without directly carrying out information interaction on a special interface developed by a signal machine manufacturer, and the information interaction can be realized by directly acquiring the change condition of the lamp color of the signal lamp, so that the signal lamp control scheme is lower in development cost, higher in applicability, more convenient to use and capable of avoiding multiple times of development.
In other embodiments, the light color change interval time may also be a light color change interval time corresponding to a light group in which a light color change occurs in the signal light, such as an interval time between when a red light changes into a green light, in this case, for a signal light whole including a plurality of light groups, one signal light step data may include a plurality of light color change interval times, such as when color changes occur in the east-west direction and the south-north direction at the same time, it is determined that two light color change interval times exist in a new signal light step data at this time, since there may be a difference between the one-time color change time in the east-west direction and the one-time color change time in the south-north direction, the two light color change interval times are different, thereby forming one signal light step data, which is used for comparing with other signal light step data to determine a period of a signal light control scheme, and further determine a specific signal light control scheme.
In an optional embodiment of the present invention, the method for determining a signal lamp control scheme further includes the steps of:
acquiring a voltage value of the signal lamp;
and determining the light color information of the signal lamp according to the voltage value.
In the embodiment of the invention, the voltage value of the signal lamp is acquired to determine the light color information of the signal lamp according to the voltage value, under a normal condition, each lamp group of the signal lamp is connected with the lamp control panel for control, and the voltage value of the signal lamp can be determined by acquiring data transmitted by the lamp control panel, so as to further obtain the light color information of the signal lamp, specifically, the voltage value of each lamp group in the signal lamp can be compared with a preset voltage value, so as to determine the lighting state of each display lamp in the lamp group, so as to determine the light color information of each lamp group, taking fig. 2 as an example, if the east of the signal lamp is accessed to three lamps of red, yellow and green of a motor vehicle by three inputs of a first lamp control panel, the three inputs respectively correspond to three channels of a digital-to-analog converter 1, 2 and 3, namely, the red lamp corresponds to channel 1, the yellow lamp to channel 2, and the green lamp corresponds to channel 3, after the digital-to-analog conversion is completed, each channel has a conversion result value, the situation that the voltage is unstable when the voltage value is set to be higher than the preset voltage value of 200V, if the conversion result of the channel 3 is greater than 200V, the east lamp group, the green lamp is considered to be bright, and if the voltage of the same as the lamp, then the lamp group of the motor vehicle is greater than the voltage of the same as 200V. Therefore, in the embodiment of the invention, the light colors of all the light groups in the signal lamp can be quickly judged through the voltage values, and the real-time universality is better.
In an optional embodiment of the present invention, the generating signal lamp step data when it is determined that the signal lamp has the light color change according to the light color information includes:
and when receiving that the first lamp group has lamp color change, generating the signal lamp step data through preset delay time, wherein the preset delay time is determined according to the number of the lamp groups.
In this embodiment, the signal lamp includes a plurality of lamp groups, correspondingly, when generating the signal lamp step data, each signal lamp step data includes a lamp color condition of each lamp group at the time of data generation, such as the signal lamp shown in fig. 2, which includes 4 lamp groups in the north, east, west, and south directions, each lamp group includes 3 display lamps, so that each direction includes 12 display lamps, for the lamp control panel connected in each direction, 12 display lamps are connected to the input ports of the lamp control panel through 12 lines, each input port corresponds to a conversion channel of a digital-to-analog converter, the conversion result of the digital-to-analog converter is the voltage value of the current channel, the on-off state of the lamp corresponding to the current channel can be determined through the voltage value, and then the state of each lamp group at the current intersection can be derived through the corresponding relationship between the channel and the display lamps, if the color of the lamp in the current direction is judged to be changed, the states of all lamp groups in the current direction are packaged, data transmission is carried out through a serial port, and then the signal lamp control scheme is determined through the signal lamp control scheme determining method.
In a specific example, for the lamp control boards in the east and west directions in fig. 2, that is, the first lamp control board and the second lamp control board detect that the lamp color changes, the lamp color information of the lamp groups in the two directions is respectively packaged and sent (the two lamp control boards work independently and do not interfere with each other), the serial port transmission data is transmitted in a queue form, the first lamp control board data first arrives at the serial port, at this time, the first lamp control board data is queued, the one-directional computing device transmits the first lamp control board data, the second lamp control board data is queued in the first lamp control board data, and transmission is started after transmission is completed, the data transmission of one lamp control board needs 10ms, the first lamp control board data needs to wait 10ms after reception is completed, the transmission of the second lamp control board data is completed, at this time, the data of the step is completely and accurately calculated, if no waiting is performed, calculation is started directly after the reception of one lamp control board data is received, and the result is incorrect. Two boards need 10ms, and then four boards need 30ms, the set delay time can be slightly longer than 30ms, so the preset delay time can be set to 40ms, after waiting for 40ms, if no new data arrives, we judge that the data reception is completed, and then complete signal lamp step data is generated for determining the signal lamp control scheme.
For the lamp group without lamp color change in the new signal lamp step data generation process, the lamp color data of the new signal lamp without data transmission adopts the data of the last step, namely, the lamp color data is kept unchanged.
In the process of generating signal lamp step data and determining a signal lamp control scheme for the first time, the two previous signal lamp step data obtained in sequence can be treated as invalid data, so that the data validity is ensured.
In an optional embodiment of the present invention, the determining a signal light control scheme according to a comparison between the signal light step data includes:
setting one of the signal lamp step data as cycle head data of one cycle of the signal lamp control scheme;
comparing the cycle header data with the signal lamp step data after the cycle header data, and determining the next cycle header data according to the comparison condition;
and determining the signal lamp control scheme according to the period head data and the signal lamp step data between the period head data and the next period head data.
In the embodiment of the invention, when the signal lamp step data are compared to determine the signal lamp control scheme, the signal lamp step data can be stored for subsequent comparison after being generated, wherein the number of steps corresponding to the signal lamp step data can be recorded in the storage process to reduce unnecessary comparison. The signal lamp control scheme operates in a period, so that one period of the signal lamp control scheme is determined, and the final signal lamp control scheme can be determined by combining various types of data of signal lamps in the period.
When the comparison is carried out, the signal lamp step data is preset as the period head data of one period of the signal lamp control scheme, it can be understood that in the operation process of the signal lamp control scheme, the signal lamp step data is continuously compared, the next period head data matched with the period head data can be found, namely, one signal lamp control scheme period is determined, the signal lamp step data between the period head data and the next period head data reflects the lamp color change condition of the lamp groups in the signal lamp control scheme period, the signal lamp step data comprises the lamp color information of all the lamp groups, correspondingly, the time information related to the lamp color information of the lamp groups can be independently determined or collected in advance after all the step data in one period are determined, and finally, the lamp color information and the time information jointly form the signal lamp control scheme.
The two types of parameters with different properties such as the light color and the light color change interval time are combined to judge whether the data are matched and correspond to each other, so that two adjacent cycle heads can be accurately judged.
In an optional embodiment of the present invention, the comparing the cycle header data with the signal lamp step data after the cycle header data, and determining the next cycle header data according to the comparison includes:
determining first signal lamp step data matched with the period head data in the signal lamp step data after the period head data as preliminary matching data;
comparing the signal lamp pace data between the period head data and the preliminary matching data with the signal lamp pace data after the preliminary matching data respectively;
if the comparison is consistent, determining the preliminary matching data as the next cycle header data;
otherwise, re-determining the next period header data in the signal lamp step data after the preliminary matching data.
In this embodiment, when the next period header data is determined in the signal lamp step data after the period header data, the first determined data matched with the period header data is regarded as preliminary matching data, and is not directly used as the next period header data, after the preliminary matching data is determined, the signal lamp step data between the period header data and the preliminary matching data is respectively compared with the signal lamp step data after the preliminary matching data, so as to determine whether the period of the signal lamp control scheme starts to repeat, for example, the period header data is the signal lamp step data of the third step, the preliminary matching data is the signal lamp step data of the twelfth step, and if the preliminary matching data is the next period header data, the signal lamp step data from the signal lamp step data of the third step to the signal lamp step data of the eleventh step should correspond to the signal lamp step data from the signal lamp step data of the twelfth step to the signal lamp step one to one signal lamp step one by one.
If the comparison is consistent in the comparison process, the period is repeated, and the initial matching data can be determined as the head data of the next period. Otherwise, it means that the preliminary matching data may be only data in one control cycle and cannot be regarded as header data of the next cycle, and therefore, in the signal lamp step data after the preliminary matching data, the search for the header data of the next cycle is performed again.
In an optional embodiment of the present invention, the comparing the cycle header data with the signal lamp step data after the cycle header data, and determining the next cycle header data according to the comparison includes:
and after the period head data are separated by a first preset number of signal lamp step data, comparing the signal lamp step data with the period head data in sequence, and determining the next period head data according to the comparison condition.
In the embodiment of the invention, the next period head data is searched after the period head data, and particularly, after the period head data is separated by the first preset number of signal lamp step data, the comparison between the signal lamp step data and the period head data is started to compare and determine the next period head data, so that the calculation workload is reduced, and the comparison efficiency is improved.
Wherein, first predetermined quantity can specifically be set for according to road traffic planning experience, for example, the intersection of four directions, there is not pedestrian's banks, every direction of motor vehicle banks is put according to green, yellow, red order, so in carrying out signal lamp step data generation, every direction has 3 steps, 4 directions 12 steps, so a signal lamp control scheme cycle probably is 12 steps, can set up first predetermined quantity at this moment and be 9, cycle head data regards as the data of step 0, so step 1-9 will not check up, reduced the number of times of comparison, promoted program efficiency.
In an optional embodiment of the present invention, the determining a signal light control scheme according to a comparison between the signal light step data further includes:
when the signal lamp step data after the period head data and the period head data are continuously compared accords with a preset comparison condition, resetting the period head data, wherein the reset period head data are the signal lamp step data spaced by a second preset number after the previous period head data;
wherein the preset comparison condition comprises: the number corresponding to the signal lamp step data generated continuously reaches a preset threshold value, and/or
And the number of the signal lamp step data compared with the period head data reaches a preset comparison number.
In some cases, the initially set cycle header data may be incorrect, and therefore, whether the determined cycle header data is incorrect and the cycle header data is reset is determined to ensure that the cycle of the signal lamp control scheme can be determined.
In addition, the number of the signal lamp step data compared with the period head data can also be determined, if the number is higher, the preset comparison number is reached, the period condition of one signal lamp control scheme is obviously not met, and the condition that the period head data is set wrongly can be shown at the moment.
In one of the above situations, the period header data may be reset, and new period header data is set in the signal light step data after the period header data, specifically, the signal light step data after the period header data may be set as the new period header data, and then the new period header data is used to determine the next period header data, where the second preset number is set to 0, and in other embodiments, the second preset number may be set to another value.
In an optional embodiment of the present invention, after determining the signal lamp control scheme, the signal lamp control scheme may be stored in the device, and the flag variable is set to 1, and the flag variable is set to 0 if the signal lamp control scheme is not determined, and when the signal lamp control scheme is changed, the flag variable may be set to 0, and corresponding data stored in the device may be subjected to a condition redetermination.
