Description

Technical Field

[0001] This invention belongs to the field of traffic light technology, specifically a Morse code traffic light system. Background Technology

[0002] With the development of technology, various wireless communication devices based on electromagnetic waves have also developed accordingly. However, in scenarios with electromagnetic interference, conventional communication methods cannot be used. In such cases, Morse code optical communication can be used for brief information exchange over distances of up to a kilometer. Currently, conventional Morse code light communication often uses manual control of the lighting duration for encoding and human visual recognition of the light signal for decoding. This method is prone to encoding errors. Meanwhile, in military applications, visible light is used as the signal light, but conventional white light signals have poor fog penetration capabilities. In rainy or foggy weather, the signal light transmission distance is short, and it cannot be used during the day. Moreover, using visible light as the signal light makes it easy for the enemy to identify and crack. Furthermore, existing technologies also use visible light lasers as the light source, which can easily cause harm to the human body. Summary of the Invention

[0007] The automatic encoding and decoding electrical control system is used to control the transmitting optical system to transmit Morse code light signals according to the input Morse code information content to transmit Morse code information. It is also used to convert the Morse code light signals into readable character signals, and to control the 360° rotating two-dimensional turntable to turn in a specified direction to realize the omnidirectional signal transmission of the Morse code signal light.

[0008] Furthermore, the emission optical system includes a laser source, an optical collimating lens system, an illumination range adjustment system, and a first optical anti-reflection window arranged sequentially along the optical axis; the emitted light from the laser source becomes parallel light after passing through the optical collimating lens system, the illumination range adjustment system adjusts the illumination range of the parallel light, and then it is incident on the first optical anti-reflection window.

[0009] Furthermore, the laser source is a near-infrared laser.

[0010] Furthermore, the illumination range adjustment system adopts a dual-lens structure, including a bracket, a slide, a stepper motor, a coaxial connector, and a near-light source lens and a far-light source lens arranged coaxially. The near-light source lens is fixed on the bracket, and the far-light source lens is mounted on the slide. The slide is mounted on the coaxial connector driven by the stepper motor. When the stepper motor rotates, it drives the slide to move along the optical axis, thereby driving the far-light source lens to move. When the focal points of the near-light source lens and the far-light source lens coincide, the parallel light remains parallel after passing through the illumination range adjustment system. When the focal points of the near-light source lens and the far-light source lens do not coincide, the parallel light becomes divergent after passing through the illumination range adjustment system.

[0011] Furthermore, the receiving optical system includes a second optical anti-reflection window, a filter, a converging lens, and a photoelectric sensor arranged sequentially along the optical axis.

[0013] Furthermore, the automatic encoding and decoding electrical control system includes a microprocessor (MCU), a laser control module, a stepper motor control module, a position switch sensor module, a photoelectric conversion module, a touch display module, and a two-dimensional turntable control module;

[0014] The microprocessor (MCU) controls the laser control module to drive the laser source to transmit Morse code information by alternating periods of brightness and duration based on the input Morse code information and brightness value.

[0015] The microprocessor (MCU) controls the stepper motor control module to drive the stepper motor to rotate according to the target value of the illumination range, thereby moving the far-light source lens to adjust the illumination range.

[0016] The microprocessor (MCU) determines whether the far-light source lens has moved to the boundary based on the signal fed back by the position switch sensor module. If it has moved to the boundary, it controls the stepper motor to stop rotating.

[0017] The microprocessor (MCU) converts the signal value sent by the photoelectric conversion module into a Morse code signal of varying lengths based on the duration of the signal value, and matches it with a pre-stored Morse code character table, thereby converting the Morse code light signal into a readable character signal.

[0018] The touch display module is used to input the Morse code information to be sent and to display the received Morse code information.

[0019] The two-dimensional turntable control module is used to control the 360° rotating two-dimensional turntable to turn in a specified direction according to the direction control signal of the microprocessor MCU, so as to realize the omnidirectional signal transmission of the Morse code signal light.

[0020] Furthermore, the laser control module uses PWM to control the duration of the laser light source's on / off state.

[0021] Furthermore, the position switch sensor module includes a first position switch sensor and a second position switch sensor disposed in the illumination range adjustment system. When the stepper motor rotates, it drives the far-light source lens on the slide to move between the first position switch sensor and the second position switch sensor.

[0043] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0044] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0045] In one embodiment, a Morse code signal light system is provided, including a transmitting optical system, a receiving optical system, an automatic encoding / decoding electrical control system, and a 360° rotating two-dimensional turntable, such as...

The transmitting optical system is used to transmit Morse code optical signals; the receiving optical system is used to receive the transmitted Morse code optical signals; the automatic encoding and decoding electrical control system is used to control the transmitting optical system to transmit Morse code optical signals according to the input Morse code information content to transmit Morse code information, and is also used to convert the Morse code optical signals into readable character signals, and to control the 360° rotating two-dimensional turntable to rotate in a specified direction to realize the omnidirectional signal transmission of the Morse code signal light.

[0046] Preferably, the transmitting optical system and the receiving optical system are integrated in a closed cavity, which is mounted on the 360° rotating two-dimensional turntable. The cavity can rotate in azimuth and pitch with the 360° rotating two-dimensional turntable, and can transmit Morse code light signals in any direction and receive Morse code light signals transmitted from any direction.

[0047] The solution adopted in this embodiment has a high degree of system integration and can effectively realize the transmission of Morse code information.

[0048] Furthermore, in one embodiment, the Morse code emission optical system designed in this invention includes a near-infrared laser source, an optical collimating lens system, an illumination range adjustment system, and a first optical anti-reflection window, such as... Figure 2 As shown.

[0049] Preferably, the laser source is a near-infrared laser. More preferably, a fiber laser with a 1064nm light source is used.

[0050] Here, a near-infrared light source that is invisible to the human eye and has strong fog-penetrating ability is used as the signal light, so that it can still be used in rainy and foggy weather and during the day, and is not easily detected by third parties.

[0051] The emitted light from the near-infrared laser becomes parallel light after passing through an optical collimating lens system, which typically employs a dual-lens setup. The illumination range adjustment system also uses a dual-lens structure, such as... Figure 3 As shown, the system includes a bracket, a slide, a stepper motor, a coaxial connector, position switch sensor 1 and position switch sensor 2, and a near-light source lens and a far-light source lens coaxially arranged. The near-light source lens is fixed on the bracket in the system, and the far-light source lens is mounted on the slide. The slide is mounted on the coaxial connector driven by the stepper motor. When the stepper motor rotates, it drives the slide to move along the optical axis between position switch sensor 1 and position switch sensor 2, thereby moving the far-light source lens and adjusting the illumination range. When the focal points of the near-light source lens and the far-light source lens in the illumination range adjustment system coincide, the parallel light remains parallel after passing through the illumination range adjustment system, and the illumination range is at its minimum. When the focal points of the far-light source lens and the near-light source lens do not coincide, the parallel light becomes divergent after passing through the illumination range adjustment system, and the illumination range increases. The illumination range changes with the distance between the near-light source lens and the far-light source lens.

[0057] Here, the second optical anti-reflection window is used to reduce reflected light and increase the amount of light entering; the filter only allows light emitted from the corresponding near-infrared laser to pass through, reducing the detection noise of the photoelectric sensor; the converging lens is used to focus the light entering the receiving optical system onto the receiving surface of the photoelectric sensor, improving the signal-to-noise ratio.
