Description

Technical Field

[0001] This utility model relates to the field of laser beam matching, and in particular to an automatic light-seeking laser beam matching device. Background Technology

[0002] Currently, laser beam matching technology is widely used in security monitoring, industrial inspection, and other fields. Among these, manual-alignment and automatic-tracking laser beam matching devices are a common existing technology. Manual-alignment laser beam matching systems typically consist of a laser transmitter, a receiver, and a manual adjustment bracket. Operators must manually adjust the angle and position of the transmitter and receiver by visual observation or with the aid of simple tools to accurately align the laser beam with the receiver and establish an effective detection optical path. However, this method has several drawbacks:

[0003] 1. Low installation and debugging efficiency:

[0004] The installation and commissioning process relies on the experience and skill of the operators, and is time-consuming, especially in complex environments or when multiple sets of beam-emitting devices are deployed at the same time, resulting in extremely low efficiency.

[0005] 2. Accuracy is difficult to guarantee:

[0006] Manual adjustment is greatly affected by human factors. The skill level and experience of different technicians vary, resulting in inconsistent light accuracy.

[0007] 3. Poor environmental adaptability:

[0008] During use, due to environmental factors such as foundation settlement, wind force, and temperature changes, the calibrated optical path may deviate. Manually adjusting the optical system lacks automatic correction capabilities and requires regular manual inspection and recalibration.

[0009] 4. Difficult to deploy at scale:

[0010] As the number of laser beam-aligning devices deployed increases, the workload of manual beam alignment grows linearly, requiring a significant investment of manpower and resources for both installation, commissioning, and subsequent maintenance.

[0011] The applicant filed a Chinese utility model patent with application number 2025215009892 entitled "A Two-Dimensional Adjustment Stage for Laser Beams", which describes how to achieve high-precision and rapid electric adjustment of the laser beam in a two-dimensional plane by adopting a high-precision transmission mechanism and a closed-loop feedback control system.

[0099] Specific Embodiment Three: Principle of an Automatic Light-Seeking Laser Beam Targeting Device

[0100] 1. Laser beam transmitter: It generates a high-energy, highly directional laser beam with good monochromaticity and coherence through an internal laser generator, and uses an optical emission system to collimate and direct the beam so that it accurately reaches the laser beam receiver.

[0101] The electric two-dimensional adjustment stage 5 automatically adjusts the transmitter's angle in the horizontal and vertical directions by ±15° according to the controller's instructions, allowing users to accurately align the beam according to the actual installation scenario. The laser diode is used to generate the laser beam, and the collimating lens collimates the diverging beam emitted by the laser diode, making it into a highly parallel laser beam for emission. The antenna 10 is used to receive the beam alignment instructions issued by the controller.

[0102] 2. Laser Beam Receiver: This is the core component of the automatic laser beam-seeking device, which realizes signal reception and processing. It captures the laser beam emitted by the transmitter through a high-sensitivity photodetector and converts the optical signal into an electrical signal. After signal amplification and filtering to eliminate environmental interference, the effective signal is transmitted to the microcontroller for sampling. The microcontroller analyzes and judges the signal. When it detects that the laser beam is blocked or the intensity is lower than the preset threshold, it triggers the alarm mechanism and outputs an alarm signal. At the same time, it uploads the device's working status and alarm information to the controller through the communication module.

[0103] Specifically, the signal acquisition circuit board 14 receives the laser beam emitted by the transmitter, converts the optical signal into an electrical signal, and performs amplification and filtering to ensure the purity of the received signal, thereby determining the received intensity of the light source. The receiver adapter board 12 supplies power to the sampling board in the receiver and is used for automatic address editing. It is also responsible for collecting temperature and humidity information.

[0104] 3. Controller: Receives laser beam alarm signals in real time. When an abnormal laser condition is detected, it quickly sends an automatic beam adjustment and beam-finding command to the laser beam transmitter. The command drives the geared motor on the electric two-dimensional adjustment stage 5 to rotate automatically according to a preset program, precisely adjusting the angle of the transmitter lens, thereby realizing automatic beam-finding and beam alignment, ensuring the stable operation of the laser beam system, and timely restoring normal beam transmission and detection functions.

[0105] Specifically, the controller has a built-in signal transmitting unit that encodes the light-seeking and light-aligning control signals according to a preset program or user-input instructions, converting them into wireless signals of a specific frequency and protocol. The wireless signals are then radiated into the surrounding space in the form of electromagnetic waves through the transmitting antenna. The laser beam transmitter, as a key component for signal reception and conversion, is equipped with a high-sensitivity signal receiving antenna 10, which can capture the wireless signals transmitted by the control module and transmit them to the built-in signal decoding chip. The decoding chip analyzes the signals and restores the original control instructions, such as "move 50 micrometers along the positive X-axis" or "fine-tune 20 micrometers along the negative Y-axis." After the laser beam receiver completes signal decoding, the longitudinal and transverse motors of the electric two-dimensional tuning stage 5 begin to rotate according to the instructions, thereby driving the laser diode and collimating lens to make precise displacements.

[0106] Specific Implementation Example 4: Controller Interface Description

[0107] As attached Figure 9 As shown, the alarm output interfaces include normally open and normally closed switch signal outputs and a DC12V output for the alarm light.

[0108] Power and signal interfaces: The power interface is for the controller, the tamper interface is for external tamper protection, the 12V output is for powering the receiver rod, the yellow-green signal interface is for receiver rod communication, the bus interface is for bus communication, and the network interface is for network communication.
