Detailed Description
The core of the application is to provide an HID lamp, a control method and a control device thereof, and a computer readable storage medium, and another object of the application is to provide a camera, so that multifunctional communication between the camera and the HID lamp can be realized on the basis of an existing line, and the image quality of supplementary lighting pictures in different application scenes can be improved and the cost can be reduced by configuring the HID lamp.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, in order to carry out the nimble configuration of exploding flashing luminance gear etc. to the operating condition of HID lamp by the camera on the basis that the HID lamp is popped and is dodged to the camera, in order to improve the suitability under multiple environment light, adopted among the prior art to add the scheme of RS485 interface and cable for camera and HID lamp, utilized serial communication between the two to dispose the HID lamp by the camera. However, this solution requires line modifications, which is not only inconvenient to implement, but also costly and limited. Another solution in the prior art is to add a photosensitive element to the HID lamp, so that self-adjustment of the HID lamp can be achieved. Although the scheme does not need to carry out large-scale line transformation between the camera and the HID lamp, the synchronization of the camera and the HID lamp in the working state cannot be kept like in the first prior art, and the light supplement picture in the transition time period is abnormal. Therefore, the application provides a control scheme of the HID lamp, the communication configuration of the camera to the HID lamp can be realized on the basis of the existing connecting line, and the synchronization of the camera and the HID lamp in the working state is kept, so that the applicability of the system under different ambient light is improved in high quality and low cost.
Referring to fig. 1, an application scenario diagram of a control method for an HID lamp is disclosed in the embodiment of the present application.
As previously described, the camera may send a trigger pulse to the controller of the HID lamp via the trigger line to trigger the HID lamp to deflagrate. In practical applications, one camera may be connected to the controllers of the plurality of HID lamps through a plurality of trigger lines, respectively. For example, the camera shown in fig. 1 is connected to the controller 1 of the HID lamp 1, the controller 2 of the HID lamp 2, and the controller 3 of the HID lamp 3 through the trigger output port 1, the trigger output port 2, and the trigger output port 3, respectively, and can perform burst flash triggering on 3 corresponding HID lamps.
Referring to fig. 2, an embodiment of the present application discloses a method for controlling an HID lamp, where the method is applied to a controller, and mainly includes:
s11: and receiving a flash triggering signal which is sent on a triggering line of the camera and comprises a triggering pulse.
It should be noted that, the method for controlling the HID lamp provided in this embodiment does not need to modify the existing connection line between the camera and the controller of the HID lamp, that is, the camera still performs single-wire transmission with the controller of the HID lamp through the trigger line. As described above, the camera sends the burst flash trigger signal including the trigger pulse through the trigger line, so as to trigger the HID lamp to perform burst flash. The burst flashing trigger signal is a switching value signal, generally, the time width of a trigger pulse is about 300 μ s, and a controller of the HID lamp outputs a driving pulse to the HID lamp at the rising edge of the trigger pulse based on an edge trigger mechanism to drive the HID lamp to burst.
It should be noted that, because the HID lamp needs a time not less than a preset time threshold in a single flashing process to meet the power-back requirement of the energy storage capacitor, the time interval between two adjacent flashing processes cannot be too small, otherwise, the second flashing trigger signal cannot be used as an effective trigger signal. The preset duration threshold is the minimum reaction duration between two times of flashing of the HID lamp, and is generally about 50 ms.
Referring to fig. 3, an embodiment of the present application discloses an invalid triggering principle of a burst trigger signal.
If the time interval between two adjacent flashing trigger signals sent from the camera side is not less than a preset time threshold, the two flashing trigger signals are both effective trigger signals; if the time interval between the flash triggering signal sent from the camera side at this time and the flash triggering signal which is sent last time and effectively triggers flash is smaller than the preset time threshold, the flash triggering signal at this time becomes an invalid triggering signal.
Therefore, after the HID lamp is effectively triggered to explode, the exploding and flashing triggering signal which is sent again in the time period after the preset time length threshold value is passed is likely to effectively trigger the exploding and flashing again, and because each exploding and flashing triggering signal has a certain signal time length, in order to ensure that all the contents of each exploding and flashing triggering signal are effectively read, as a preferred implementation mode, the signal time length of the exploding and flashing triggering signal is smaller than the preset time length threshold value which is the minimum reaction time length between two times of exploding and flashing of the HID lamp.
S12: and acquiring a corresponding configuration instruction according to the parameter characteristics of the trigger pulse.
It should be noted that, in this embodiment, the camera not only sends the burst flash trigger signal through the trigger wire to trigger the burst flash of the HID lamp, but also transmits the relevant information of the configuration command through the trigger wire, so that the controller performs the status configuration on the burst flash of the HID lamp. Specifically, a configuration command of the HID lamp by the camera is sent to the controller by means of a burst trigger signal. According to a certain information processing rule, a mapping relation between a configuration instruction and the parameter characteristics of the trigger pulse can be established, and after the controller receives the burst flash trigger signal comprising the trigger pulse, the corresponding configuration instruction can be analyzed according to the parameter characteristics of the trigger pulse in the burst flash trigger signal based on the information processing rule.
It should be noted that the parameter characteristics of the trigger pulse include, but are not limited to, the width and the interval time of the trigger pulse, and the digital signal coding that follows, and those skilled in the art can select and set the parameter characteristics according to the requirements of the actual application scenario, and this embodiment does not limit this.
S13: and configuring the HID lamp according to the configuration instruction.
It is easy to understand that the configuration instruction can be generated according to the instruction information input by the user, and also can be generated by the camera according to the specific light supplement requirement under the current ambient light condition, so that the clear and high-quality light supplement picture can be obtained under the current ambient light condition by reasonably configuring the flashing state of the HID lamp.
The specific contents of the configuration command are not limited in the present application. For example, the configuration instruction may specifically be a brightness step configuration instruction of the HID lamp, configured to configure the flashing brightness step of the HID lamp to a high-grade, a medium-grade, or a low-grade according to the natural light brightness in the current environment; for another example, for an HID lamp with an infrared filter, the configuration instruction may also be specifically an infrared filter start configuration instruction, and may be used to configure the burst flash operating mode of the HID lamp to an infrared filter-free burst flash mode suitable for daytime use, or an infrared filter burst flash mode suitable for night use and capable of reducing harm to eyes of a driver.
In addition, in the embodiment, the camera specifically uses the burst flashing trigger signal to transmit the configuration instruction of the HID lamp, that is, the camera performs burst flashing trigger control and configuration on the HID lamp, so that the synchronization of the configuration of the working state of the HID lamp and the working mode of the camera is effectively ensured, and the abnormal situation of the light supplement picture in the transition time period can be effectively avoided.
It should also be noted that configuring the HID lamp according to the configuration command and implementing the configuration command effect are preferably performed out of synchronization in time. In consideration of timeliness of light supplement of the HID lamp, that is, in order to avoid missing an optimal opportunity for light supplement of a passing vehicle approaching the camera, as described above, the controller generally sends a driving pulse to the HID lamp when detecting a rising edge of the trigger pulse, so as to control the HID lamp to flash to supplement light to the environment in time. Therefore, there is a certain time difference between the analysis and the effect realization of the configuration command, that is, the specific configuration effect of the configuration command transmitted in the current burst trigger signal is reflected in the burst triggered by the rising edge of the next trigger pulse. Specifically, the HID lamp may be configured immediately after the configuration instruction is analyzed, and specifically, the corresponding configuration parameter may be written into the corresponding register to be called when the next flash burst occurs.
The control method of the HID lamp provided by the embodiment is applied to a controller, and comprises the steps of receiving a flash triggering signal which is sent by a triggering line of a camera and comprises a triggering pulse; acquiring a corresponding configuration instruction according to the parameter characteristics of the trigger pulse; and configuring the HID lamp according to the configuration instruction. Therefore, the camera is sent to the controller of the HID lamp by means of the flash triggering signal aiming at the configuration instruction of the HID lamp, the multifunctional communication between the camera and the HID lamp is realized based on the original connecting circuit, the state configuration can be carried out on the flash of the HID lamp according to different application scenes, the synchronism of the working states of the camera and the HID lamp is guaranteed, the image quality of the light supplementing picture and the applicability of the system under various application scenes are effectively improved, and the method is free from circuit transformation, simple and easy to implement and effectively saves the cost.
Referring to fig. 4, an embodiment of the present application discloses a specific HID lamp control method, which is applied to a controller and mainly includes:
s21: and receiving a flash triggering signal which is sent on a triggering line of the camera and comprises a triggering pulse.
S22: and determining a configuration instruction corresponding to the pulse width of the trigger pulse based on a preset mapping relation between the pulse width and the configuration instruction.
It should be noted that the parameter characteristic of the trigger pulse in this embodiment specifically refers to the pulse width of the trigger pulse. As mentioned above, the time width of the trigger pulse is generally about 300 μ s, and therefore, the transmission mechanisms with different pulse widths can be designed based on 300 μ s.
Referring to fig. 5, the embodiment of the present application discloses a schematic diagram of HID lamp brightness step configuration based on pulse width.
Taking the brightness step configuration command as an example, if the brightness of the HID lamp during the flash may be adjusted to two steps of "high brightness" and "low brightness", for the trigger pulse, a pulse width of 200 μ s may be used to represent the "low brightness" step, and a pulse width of 300 μ s may be used to represent the "high brightness" step. Similarly, since the controller generally controls the HID lamp to perform the deflagration using the driving pulse, the pulse width of the driving pulse in the low brightness step may be set to 200 μ s, and the pulse width of the driving pulse in the high brightness step may be set to 300 μ s.
In the schematic diagram shown in fig. 5, the camera sequentially sends three effective burst flashing triggering signals, and correspondingly, the controller sends three driving pulses to the HID lamp to control the HID lamp to perform burst flashing for three times.
The pulse width of the trigger pulse in the first time of the burst flashing trigger signal is 200 mus, therefore, the controller can determine that the current first brightness gear configuration instruction is a low brightness gear configuration instruction according to the pulse width of 200 mus at the falling edge moment of the trigger pulse, so as to configure the brightness gear of the HID lamp, and control the HID lamp to carry out low brightness gear burst flashing according to the current configuration result at the rising edge of the second time of the trigger pulse, namely, a driving pulse with the pulse width of 200 mus is output to the HID lamp.
The pulse width of the trigger pulse in the second time of the burst flashing trigger signal is 300 mus, therefore, the controller can determine that the current second time brightness gear configuration instruction is the high brightness gear configuration instruction according to the pulse width of 300 mus at the falling edge time of the trigger pulse, so as to configure the brightness gear of the HID lamp, and control the HID lamp to carry out high brightness gear burst flashing according to the configuration result of the current time at the rising edge of the third time trigger pulse, namely, the drive pulse with the pulse width of 300 mus is output to the HID lamp.
Similarly, the pulse width of the trigger pulse in the third burst trigger signal is 300 μ s, so that the controller can determine that the third brightness step configuration command is the high brightness step configuration command according to the pulse width of 300 μ s at the falling edge time of the trigger pulse, thereby configuring the brightness step of the HID lamp, and control the HID lamp to perform high brightness step burst according to the configuration result at the rising edge of the fourth trigger pulse (not shown in fig. 5), that is, output the driving pulse with the pulse width of 300 μ s to the HID lamp.
It should be noted that, when the configuration command is obtained by analyzing the pulse width of the trigger pulse, an appropriate error margin may be set for the pulse width so as to ensure effective transmission and identification of information. For example, the error margin may be set to 50 μ s, and a pulse width in the range of 150 μ s to 250 μ s may represent a "low brightness" step; pulse widths in the range of 250-350 μ s can all represent "high brightness" levels.
S23: and configuring the HID lamp according to the configuration instruction.
Referring to fig. 6, the embodiment of the present application discloses another specific HID lamp control method, which is applied to a controller and mainly includes:
s31: receiving a flash triggering signal which is sent on a triggering line of a camera and comprises a triggering pulse; the burst trigger signal comprises a first trigger pulse and a second trigger pulse.
S32: and determining a configuration instruction corresponding to the pulse interval between the first trigger pulse and the second trigger pulse based on a mapping relation between a preset pulse interval and the configuration instruction.
It should be noted that the burst trigger signal in this embodiment includes two trigger pulses, namely a first trigger pulse and a second trigger pulse, and the parameter characteristic of the trigger pulse in this embodiment specifically refers to a pulse interval between the first trigger pulse and the second trigger pulse. In particular, for the sake of timeliness, the pulse interval is preferably the interval duration between the rising edge time of the first trigger pulse and the rising edge time of the second trigger pulse. Of course, the pulse interval may also be the interval duration between the falling edge time of the first trigger pulse and the falling edge time of the second trigger pulse.
It should be added that, the duration of the pulse interval between the first trigger pulse and the second trigger pulse needs to be limited, so as to avoid that the pulse interval is too long and is greater than a preset duration threshold, which causes the controller to mistakenly regard the second trigger pulse as the first trigger pulse in the next burst trigger signal. For example, still taking the brightness step configuration command as an example, if the brightness of the HID lamp during the flash can be adjusted to two steps of "high brightness" and "low brightness", a pulse interval of 200 μ s can be used to represent the "low brightness" step, and a pulse interval of 300 μ s can be used to represent the "high brightness" step.
S33: and configuring the HID lamp according to the configuration instruction.
Referring to fig. 7, the embodiment of the present application discloses another specific HID lamp control method, which is applied to a controller and mainly includes:
s41: and receiving a flash triggering signal which is sent on a triggering line of the camera and comprises a triggering pulse.
S42: and determining a configuration instruction corresponding to the digital signal code following the trigger pulse based on a mapping relation between preset digital signal codes and the configuration instruction.
It should be noted that the parameter characteristic of the trigger pulse in this embodiment specifically refers to the digital signal code following the trigger pulse. It is easy to understand that the burst trigger signal is a switching value signal, and digital signal codes can be transmitted by using high and low levels. By presetting the mapping relation between the designated digital signal code and the configuration command, the camera can send the configuration command to the controller by transmitting the digital signal code.
The specific format of the digital signal coding can be selected and set by a person skilled in the art, and the embodiment does not limit this. For example, the digital signal code may specifically include 7 data bits with a value of 0 or 1, and the duration of each data bit may specifically be 4ms, so that the total duration of the digital signal code is 28ms. Thus, with a digital signal encoding consisting of said 7-bit data bits, a maximum of 127 different configuration instructions can be characterized. Still taking the configuration command of the brightness level as an example, if the brightness of the HID lamp during the flash burst can be adjusted to three levels, namely "high brightness", "medium brightness", and "low brightness", the digital signal codes respectively corresponding to the configuration commands of the brightness levels can be specifically shown in table 1.
TABLE 1
| Brightness gear configuration instruction | Digital signal coding |
| Low-brightness gear configuration instruction | 1111001 |
| Medium brightness gear configuration instruction | 1111010 |
| High brightness gear configuration command | 1111011 |
S43: and configuring the HID lamp according to the configuration instruction.
Referring to fig. 8, the embodiment of the present application discloses another specific HID lamp control method, which is applied to a controller and mainly includes:
s51: and receiving a flash triggering signal which is sent on a triggering line of the camera and comprises a triggering pulse.
S52: performing initial check on a start bit of a digital signal code following the trigger pulse; if the initial verification passes, the process proceeds to S53.
In this embodiment, in order to improve efficiency and identify data transmission errors early, a start bit check mechanism is provided for digital signal encoding. For example, the start bit of the standard may be specifically set to 4 data bits, and the value may be specifically 0101. After receiving a digital signal code following a trigger pulse, judging whether the digital signal code takes 0101 as an initial bit, if so, judging that initial verification passes and executing subsequent steps; if not, the initial verification is judged not to pass, and the processing procedure of this time is directly ended.
S53: performing parity check on the parity check bits encoded by the digital signal; if the parity check passes, the process proceeds to S54.
Similarly, in the present embodiment, in order to further verify the accuracy of data transmission, a parity check mechanism is provided for the data bits encoded by the digital signal. In particular, parity bits may be added at the end of the digital signal encoding and may specifically characterize the number of bits of the data bits as even with 0's and odd with 1's.

Specifically, as described above, in order to ensure timely light supplement for a passing vehicle approaching the camera, when a burst flash trigger signal including a trigger pulse is received, the controller may start to transmit a driving pulse corresponding to the current configuration to the HID lamp at a rising edge of the trigger pulse based on an edge trigger mechanism, so as to control the HID lamp to perform burst flash. It will be readily appreciated that the current configuration is the current configuration at the time of the detection of the rising edge of the trigger pulse, i.e. the configuration specified by the configuration instruction transmitted in the last burst trigger signal.
S63: and acquiring a corresponding configuration instruction according to the parameter characteristics of the trigger pulse.

Referring to fig. 11, an embodiment of the present application discloses a flowchart of another HID lamp control method, which is applied to a camera and mainly includes:
s71: determining a configuration instruction for the HID lamp.
It should be noted that the configuration command may be specifically determined according to command information input by the user, and may also be specifically generated by the camera according to the current vehicle passing condition. In general, in a mount system, a camera is connected to a sensor for detecting passing information of a vehicle, such as a radar, through a relevant communication line. When the vehicle passes by, the sensor sends a vehicle passing notification signal to the camera, so that the camera triggers the HID lamp to perform flashing and light supplementing, and simultaneously starts a shooting task.
S72: and determining the trigger pulse with the corresponding parameter characteristic according to the configuration instruction.
As mentioned above, according to a certain information processing rule, a mapping relationship between the configuration command and the parameter characteristics of the trigger pulse can be established. Based on the information processing rules, the camera may determine trigger pulses with corresponding parameter characteristics, i.e. trigger pulses carrying relevant information of configuration instructions.
S73: and sending the burst flash trigger signal comprising the trigger pulse to a controller through a trigger line so that the controller can obtain the configuration instruction according to the parameter characteristics and configure the HID lamp according to the configuration instruction.

Referring to fig. 12, an embodiment of the present application discloses a flowchart of another HID lamp control method, which is applied to a camera connected to a controller, and mainly includes:
s81: determining a configuration instruction for the HID lamp.
S82: and determining the trigger pulse with the corresponding parameter characteristic according to the configuration instruction.
S83: judging whether a vehicle passing notification signal sent by a sensor is received; if the vehicle passing notification signal is received, entering S84; and if the passing vehicle notification signal is not received, continuing to execute S83.
Because this application utilizes to explode to dodge triggering signal to transmit the configuration instruction specifically, consequently, under normal condition, will trigger the HID lamp and explode and dodge after having sent to explode to dodge triggering signal or configuration instruction. In fact, the configuration command may be input by the user, that is, there is not necessarily a passing vehicle passing through the camera, and then the HID lamp is triggered to flash at this time, which inevitably results in waste of resources.
Therefore, in the embodiment, before the camera sends the flash triggering signal carrying the configuration instruction, whether the vehicle passing notification signal is received or not is judged, and if yes, the subsequent steps can be continuously executed to send the flash triggering signal; if not, the configuration instruction is determined by instruction information input by a user, and no passing vehicle passes through the configuration instruction, so that a continuously judged waiting program can be entered, and the camera sends the flash triggering signal carrying the configuration instruction again until the passing vehicle passes through the flash triggering signal.
S84: judging whether the interval time from the last transmission is not less than a preset time threshold; the preset time threshold is the minimum reaction time between two times of flash explosion of the HID lamp; and if the interval time is not less than the preset time threshold, entering S85.
As described above, if the interval duration of the two flashing trigger signals is less than the preset duration threshold, the second flashing trigger signal will be an invalid trigger signal, and the HID lamp cannot be triggered even if the second flashing trigger signal is sent to the controller. Therefore, in this embodiment, the camera determines the interval duration of the two flashing trigger signals, and if the interval duration is less than the preset duration threshold, the processing procedure may be directly ended, that is, the flashing trigger signal is sent only after the interval duration is determined to be not less than the preset duration threshold, so as to further save power consumption and reduce the usage damage degree of the HID lamp.
