Specific implementation manners

[0039] To describe in detail the technical content, achieved objectives and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.

[0040] An embodiment of the present utility model provides an automatic alarm marker post, including a marker post body, and the marker post body includes a video acquisition unit, a processing unit and an alarm unit;

[0041] The video acquisition unit is connected to the input end of the processing unit, and the output end of the processing unit is connected to the input end of the alarm unit;

[0042] The video acquisition unit is used to acquire video information around the marker post body;

[0043] The processing unit is used to generate an alarm instruction according to the video information acquired by the video acquisition unit;

[0044] The alarm unit is used to perform an alarm operation according to the alarm instruction output by the processing unit.

[0045] As can be seen from the above description, the beneficial effects of the present utility model are as follows: A video acquisition unit is provided on the identification pile body to collect video information around the identification pile body and transmit it to the processing unit. The processing unit performs intelligent analysis based on the video information to determine whether there is a dangerous situation around the identification pile body. When there is a dangerous situation, the processing unit generates an alarm instruction and transmits it to the alarm unit, and the alarm unit performs corresponding alarm operations according to the alarm instruction, thereby reminding pedestrians or target personnel that there is danger in the current environment. In this way, the identification pile can automatically sense the surrounding environmental conditions and actively provide alarm information to pedestrians, avoiding the problem that pedestrians do not observe the identification pile, optimizing the warning effect, and effectively eliminating potential safety hazards.

[0046] Further, the video acquisition unit includes a camera, an analog-to-digital conversion chip, and an MIPI signal interface;

[0047] The camera is connected to the input end of the analog-to-digital conversion chip, and the output end of the analog-to-digital conversion chip is connected to the input end of the processing unit through the MIPI signal interface.

[0048] As can be seen from the above description, the video information collected by the camera passes through the analog-to-digital conversion chip, converts the optoelectronic analog signal into a digital signal, and then transmits it to the processing unit through the MIPI signal interface. The MIPI signal interface uses serial communication to transmit data, which can greatly reduce the number of lines during data transmission, making the system simpler and more reliable. And using differential signal transmission can effectively cancel out noise and interference, thereby ensuring the video transmission quality while reducing the system cost.

[0049] Further, the alarm unit includes an LED driving circuit, an LED lamp device, a power amplifier circuit, and a speaker device;

[0050] The output end of the processing unit is respectively connected to the control ends of the LED driving circuit and the power amplifier circuit. The output end of the LED driving circuit is connected to the LED lamp device, and the output end of the power amplifier circuit is connected to the speaker device.

[0051] As can be seen from the above description, alarm operations are carried out in two ways of sound and light, effectively avoiding the problem that the alarm information is ignored due to environmental influence in the case of a single alarm method, and improving the scene adaptability of the identification pile.

[0052] Further, the analog-to-digital conversion chip includes a control signal end, a power supply signal end, an input data end, and an output data end;

[0053] The camera is respectively connected to the control signal end and the input data end. The MIPI signal interface is connected to the output data end, and the power supply signal end is used to connect to the power supply.

[0054] As described above, the camera captures video information and synchronously transmits the video information to the analog-to-digital conversion chip through the control signal terminal and the input data terminal for processing. After the analog-to-digital conversion chip finishes processing, it is transmitted to the processing unit through the MIPI signal interface. In this way, the optoelectronic analog signal is converted into a digital signal, facilitating the subsequent intelligent analysis and processing of the video information by the processing unit.

[0055] Further, the model of the analog-to-digital conversion chip is SC200AI; the camera is a fixed-focus lens.

[0056] As described above, the SC200AI chip can adapt to various scenarios and can ensure the universality of the identification stake.

[0057] Further, the processing unit includes an audio signal terminal, a lamp signal terminal, and a data acquisition terminal;

[0058] The audio signal terminal is respectively connected to the input terminal and the control terminal of the power amplifier circuit, the lamp signal terminal is connected to the control terminal of the LED driving circuit, and the data acquisition terminal is connected to the video acquisition unit.

[0059] As described above, the audio signal terminal of the processing unit outputs specific audio information to the speaker device based on the input terminal of the power amplifier circuit, and at the same time controls the startup and shutdown of the speaker device based on the control terminal of the power amplifier circuit, thereby realizing the drive management of the speaker device. At the same time, the lamp signal terminal of the processing unit controls the lighting and extinguishing of the lamp device based on the control terminal of the LED driving circuit, thereby realizing the drive management of the lamp device. In addition, the data acquisition terminal of the processing unit receives the video information of the video acquisition unit for intelligent analysis and processing to determine whether to alarm currently.

[0060] Further, the LED driving circuit includes a red light control circuit and a blue light control circuit; both the red light control circuit and the blue light control circuit include a driving chip;

[0061] The lamp signal terminal is connected to the enable terminal of the driving chip, the sensing terminal and the output terminal of the driving chip are connected to the LED lamp device, and the power supply terminal of the driving chip is used to connect to the power supply.

[0062] As described above, by alternately flashing the red light and the blue light, the alarm information of the identification stake is made more eye-catching and is easy to be noticed by pedestrians or target personnel, optimizing the light warning effect.

[0063] Further, the power amplifier circuit includes a digital power amplifier chip;

[0064] The audio signal terminals are respectively connected to the input terminal, mode terminal, and drive terminal of the digital power amplifier chip. The output terminal of the digital power amplifier chip is connected to the speaker device, and the power supply terminal of the digital power amplifier chip is used to connect to a power supply.

[0065] As can be seen from the above description, the digital power amplifier chip is used to control the speaker device to output audio, and can effectively control the relevant parameters of the speaker device to optimize the sound warning effect according to environmental information.

[0066] Furthermore, the power amplifier circuit further includes a power supply filtering circuit; the power supply filtering circuit includes a first magnetic bead and a plurality of power supply filtering capacitors;

[0067] The power supply terminal of the digital power amplifier chip is respectively connected to one end of the first magnetic bead and the plurality of power supply filtering capacitors. The other end of the first magnetic bead is used to connect to a power supply, and the other ends of the plurality of power supply filtering capacitors are all grounded.

[0068] As can be seen from the above description, power supply filtering can effectively reduce the noise and clutter in the power supply. At the same time, the magnetic bead in the circuit can prevent high-frequency noise from entering the power line, protecting other devices from noise interference, thereby reducing the noise level of the power amplifier circuit and ensuring that the high-frequency components in the audio signal can be transmitted smoothly, thus maintaining the integrity and clarity of the sound quality.

[0069] Furthermore, the power amplifier circuit further includes a signal filtering circuit; the signal filtering circuit includes a second magnetic bead, a third magnetic bead, a first signal filtering capacitor, a second signal filtering capacitor, and a signal filtering resistor; the output terminal of the digital power amplifier chip includes a power supply drive terminal and a power supply control terminal;

[0070] The power supply drive terminal of the digital power amplifier chip is respectively connected to one end of the first signal filtering capacitor, the signal filtering resistor, and the second magnetic bead. The other end of the signal filtering resistor is connected to one end of the second signal filtering capacitor;

[0071] The other end of the second signal filtering capacitor is respectively connected to the power supply control terminal of the digital power amplifier chip, the other end of the first signal filtering capacitor, and one end of the third magnetic bead;

[0072] The other ends of the second magnetic bead and the third magnetic bead are both connected to the speaker device.

[0073] As can be seen from the above description, signal filtering can effectively filter out the high-frequency noise and interference on the current signal line, ensuring the stable transmission of the signal. At the same time, since the magnetic bead in the circuit also has the ability to absorb electrostatic pulses, it can protect the circuit from electrostatic interference to a certain extent.

At the same time, the speaker device emits a warning sound to remind pedestrians or mechanical equipment operators to pay attention to the surrounding environment.

The processing unit performs intelligent analysis based on the video data to determine whether there is a dangerous situation around the marker post body. When there is a dangerous situation, the processing unit generates an alarm instruction and transmits it to the alarm unit. The processing unit drives the LED driving circuit and the power amplifier circuit respectively based on the pin levels for sound and light warning, thereby reminding pedestrians or target personnel that there is danger in the current environment. In this way, the marker post can automatically sense the surrounding environment conditions and actively provide alarm information to pedestrians, avoiding the problem that pedestrians fail to observe the marker post, optimizing the warning effect, and effectively eliminating potential safety hazards.
