Other features and effects of the present invention will be apparent from the embodiments of the present invention, wherein: FIG. 1 is a main flow diagram of an embodiment of the traffic violation warning method of the present invention; and FIG. 2 is a driving record of the present invention. A main circuit block diagram of an embodiment of the device.

Referring to FIG. 1 , it is a main flowchart of an embodiment of the traffic violation warning method of the present invention. The embodiment is applied to a row of vehicle recording device disposed in a vehicle, and as shown in FIG. 2 , the driving of the embodiment is as shown in FIG. 2 . The recording device 1 mainly includes an image capturing unit 11, a digital signal processor (DSP) 12 electrically coupled to the image capturing unit 11, and an acceleration sensor 13 electrically coupled to the digital signal processor 12, respectively. (also referred to as a gravity sensor G-Sensor), an output unit 14 and a storage unit 15; wherein the image capturing unit 11 mainly comprises a digital camera 111 and an analog/digital converter 112, the digital camera 111 mainly photographs the vehicle Front environment and traffic conditions And generating an analog video signal output to the analog/digital converter 112, and converting the analog video signal into a digital video signal by the analog/digital converter 112, and outputting it to the digital signal processor 12.

The digital signal processor 12 performs appropriate compression processing on the digital video signal, and outputs the compressed video signal to the storage unit 15 for storage, for example, in a read only memory (ROM) 151 included in the storage unit 15, and the read only The memory (ROM) 151 can be a built-in memory or an external memory card. In addition, the storage unit 15 further includes a random access memory (RAM) 152, which is mainly used as a temporary register when the digital signal processor 12 processes the image signal.

The acceleration sensor 13 senses the speed, direction, vibration, and the like between the vehicles to reflect the driving condition of the vehicle, so the sensing signal generated by the acceleration sensor 13 will reflect the vibration amplitude of the vehicle, that is, the reaction driving recorder 1 The magnitude of the shock. Therefore, when the vibration amplitude of the driving recording device 1 is large while the vehicle is traveling, the value of the sensing signal generated by the acceleration sensor 13 is relatively high, and when the vehicle stops moving, the vibration amplitude of the driving recording device 1 is small. The value of the sensing signal generated by the acceleration sensor 13 is relatively low. Therefore, when the vehicle is idling (the parking is waiting, the engine is not turned off), the vibration amplitude of the driving recorder 1 is maintained within a certain range of vibration amplitude. Therefore, the value of the sensing signal generated by the acceleration sensor 13 will also be correspondingly maintained within a certain range of values.

In addition, the output unit 14 can include a speaker 141 and a display 142 (eg, an LCD display) or at least one of the two. Therefore, if the output unit 14 includes the display 142, the digital signal processor 12 The digital image signal processed by the appropriate image can also be output to the display 142 for display.

The traffic violation warning method of the present embodiment is implemented by the above-described driving recording apparatus 1, and includes the following steps. First, when the vehicle is started, the driving recorder 1 is powered on, and the image capturing unit 11 starts capturing images and transmitting them to the digital signal processor 12, while the acceleration sensor 13 detects the driving recorder 1 (ie, The vibration state of the vehicle). Then, as shown in step S1 of FIG. 1, the digital signal processor 12 determines whether the vehicle is moving according to the image captured by the image capturing unit 11. That is, the digital signal processor 12 compares successive images to determine whether the vehicle is moving. In one embodiment, the alignment is to divide the picture into a plurality of tiles or pixels, and over a period of time, compare the extent to which the tiles or pixels are compared to adjacent tiles or pixels. If the degree of change is less than a certain preset value, it is determined that the vehicle is currently in an idle state. In another embodiment, the digital signal processor 12 selects a target as a reference for determining whether to move, for example, selecting a traffic sign to identify the location/size of the traffic signal relative to the overall picture over a period of time. If the degree of change in the position/size ratio is less than a certain preset value, it is determined that the vehicle is currently in an idle state. It must be noted that there are many ways/algorithms that can be used to determine whether or not the subject of a continuous image is moving. The above methods are by way of example only and not limitation. In addition, in one embodiment, the digital signal processor 12 can also determine whether the vehicle body signal from the vehicle itself, such as the input voltage change, the input current change, or the wireless message including the engine speed or the tire speed. Compare successive images to determine if the vehicle is moving.

For example, if the engine speed is lower than 800 rpm when the vehicle is idling, when the digital signal processor 12 finds that the engine speed is lower than 800 rpm, the continuous image signal transmitted from the image capturing unit 11 is started, for example, The continuous image screen transmitted from the image capturing unit 11 in 5 seconds is compared to thereby determine whether the vehicle is moving. In another embodiment, the image capturing unit 11 continuously compares the continuous image frames transmitted by the image capturing unit 11 within a certain period of time after starting, thereby determining whether the vehicle is moving. If the digital signal processor 12 determines that the vehicle has not moved according to the image captured by the image capturing unit 11, the step S2 is performed, and the digital signal processor 12 then determines whether the vehicle is idle based on a sensing signal provided by the acceleration sensor 13. For example, when the digital signal processor 12 receives the sensing signal from the acceleration sensor 13, if the value of the sensing signal continues to fall within the numerical range corresponding to the idle state of the vehicle, it is determined that the vehicle is in an idle state, and Step S3, the digital signal processor 12 determines whether the vehicle has not moved and whether the vehicle idle speed has reached a preset violation time. If yes, proceeding to step S4, the control output unit 14 outputs a warning signal to remind the vehicle driver to drive the vehicle engine. Turn off the fire.

More specifically, in step S3, the digital signal processor 12 starts counting and continuously determines whether the vehicle is still idle, that is, whether the sensing signal of the acceleration sensor 13 is maintained within a certain range of values, and if so, The timing is continuously counted until the accumulated time reaches the preset violation time, for example, 3 minutes, that is, the warning signal is generated and output to the output unit 14. In another embodiment, it is determined whether the sensing signal of the acceleration sensor 13 is maintained within a certain numerical range, and the image capturing unit 11 is determined to be obtained. Whether the continuous image screen still shows that the vehicle is not moving, if the sensing signal is maintained within a certain value range and the continuous image screen indicates that the vehicle has not moved to reach the preset violation time, the warning signal is generated and output to the output unit. 14. The warning signal may be an audio signal, such as voice or voice, and the output unit 14 outputs the audio signal by the speaker 141. In another embodiment, the warning signal may be an image signal, and the output unit 14 outputs the image signal from the display 142. When the warning signal includes both the audio signal and the image signal, the output unit 14 outputs the audio signal and The image signals are output by the speaker 141 and the display 142, respectively.

In addition, as shown in FIG. 2, the driving recorder 1 of the present embodiment may further include a wireless communication module 16, such as Bluetooth, WiFi, ZigBee, NFC, etc., so that the driving recorder 1 can be combined with an electronic device 2, for example, support The mobile communication device of the wireless communication module, such as a driver's mobile phone, an Ipad or a mobile computer, performs wireless communication. Therefore, when the digital signal processor 12 determines that the vehicle idle violation occurs, the digital signal processor 12 can generate a return violation message in addition to the control output unit 14 to output the warning signal, and transmit the reward violation message through the wireless communication module 16. To the electronic device 2. Moreover, the electronic device 2 can also transmit the report of the violation violation via a wireless network to a remote device, such as a taxi fleet management server, through an application preloaded therein. The content of the reward violation message includes at least one identification code of the driving recorder 1 and a code of the idle violation. In another embodiment, the wireless communication module 16 can directly transmit the violation message to a fleet management server via a mobile network (eg, 3G, 4G, 5G signals) or a radio module.

In addition, as shown in FIG. 2, the driving recorder 1 of the present embodiment generally further includes a global satellite positioning (GPS) module 17, so that the digital signal processor 12 can also use the global satellite when generating the reward violation message. The positioning information currently provided by the positioning module 17 is that the current geographic location of the vehicle is included in the reward violation message, and the reward violation message is transmitted through the wireless communication module 16.

In summary, the driving recorder of the above embodiment determines whether the vehicle is idling according to the captured image and the sensing signal provided by the acceleration sensor, and promptly sends a warning signal to remind the driver of the vehicle to turn off the fire so that the vehicle does not idle. It is sometimes a violation of traffic rules and avoids air pollution, and indeed achieves the efficacy and purpose of the present invention.
