Description

Technical Field

[0001] The present invention relates to the technical field of infrared laser modules, and more specifically, to a modular quick-release detection interface infrared laser module. Background Art

[0002] Infrared laser module is an integrated component with infrared laser as the core emission source, usually composed of laser emission unit, drive circuit, optical shaping system, heat dissipation structure and power management circuit, etc. It can output infrared laser in a specific wavelength range (such as 780nm, 850nm, 940nm, etc.) for distance measurement, target recognition, trajectory detection, environmental perception and other scenarios. It has technical advantages such as high directivity, high stability and strong anti-interference ability, and is widely used in security monitoring, industrial automation, medical testing and intelligent equipment. Based on the traditional infrared laser module, the modular quick-release detection interface infrared laser module introduces a number of innovative designs such as structural modularization, interface detection and quick-release mechanism: through modular construction, each functional unit (such as laser components, power supply interfaces, signal processing units, etc.) can be replaced and combined independently, greatly improving the flexibility and adaptability of the system; through the quick-release structure design, the module can be quickly installed and disassembled during equipment maintenance, replacement or upgrade, significantly shortening the operation time; at the same time, the module integrates a dedicated detection interface, which can achieve precise connection and communication with the host computer, detection host or control system, and ensure the stability and controllability of signal transmission. This structure not only improves the versatility of infrared laser modules in industrial and intelligent equipment, but also provides efficient and reliable technical solutions for diversified application scenarios.

[0003] The existing technology has the following deficiencies: When infrared laser modules are used in high-frequency maintenance scenarios such as automated assembly production lines, operators are often required to quickly replace or adjust the modules during the operation of the equipment. At this time, the module is connected to the external signal line through a quick-release detection interface. Under such high-frequency, space-constrained, and frequent blind plug-in conditions, incomplete contact between the plug and the socket is prone to occur. Since the existing quick-release structure generally lacks an effective insertion guide mechanism, contact compensation structure, and insertion status confirmation feedback, when the plug is not fully inserted or the insertion direction is skewed, the connection between the module and the external system will be in an unstable state. The existing modular quick-release detection interface infrared laser module cannot effectively avoid such communication failures, signal loss, or false alarms caused by incomplete contact, which in turn leads to abnormal operation of the detection module, disordered control logic, and even misjudgment, shutdown, or product detection errors of the entire system, which seriously affects production efficiency and system stability.

[0023] The mounting mechanism 3 is used to firmly mount the entire infrared laser module on the fixed base 1, which can usually be realized by a slide rail buckle structure, a screw positioning mounting structure or an elastic lock structure, so as to realize the rapid assembly and disassembly of the module; the infrared laser emission module 4 is used to output infrared laser signals, and has an infrared laser, a collimating lens and a heat dissipation base integrated inside, which can be fixed in the housing 2 by screws or a pressing plate, so that it has a stable light emission direction and thermal management capability; the signal converter 5 is used to convert the electrical signal from the external system into a control signal recognizable by the infrared laser module, or convert the data collected inside the module into a standard communication format for external output, which is usually realized in the form of a communication interface chip, a level conversion circuit or an embedded microcontroller; the detection interface 6 is used to quickly connect with the external signal line to realize the functions of power input, signal transmission and reception, etc. Its structure usually includes a conductive jack, a positioning slot, a foolproof structure and an internal line connected to the signal converter 5, which is used to ensure the reliability and standardization of the external connection. This structural system together constitutes the basic functional support and external adaptation mechanism of the infrared laser module.

[0024] In this embodiment, the plug-in calibration mechanism 8 includes a mounting plate 801, a first electric push rod 802, a first fixing frame 803, a connecting plate 804, a second electric push rod 805, a second fixing frame 806 and a clamping plate 807. One side of the mounting plate 801 is fixedly connected to one side of the shell 2, and the other side of the mounting plate 801 is fixedly connected to one side of the first electric push rod 802. The outer wall of the telescopic rod of the first electric push rod 802 is fixedly connected to the inner wall of the first fixing frame 803, and one side of the first fixing frame 803 is fixedly connected to one side of the detection interface 6. The output end of the telescopic rod of the first electric push rod 802 is fixedly connected to one side of the connecting plate 804, and the other side of the connecting plate 804 is fixedly connected to one side of the second electric push rod 805. The outer wall of the telescopic rod of the second electric push rod 805 is fixedly connected to the inner wall of the second fixing frame 806, and one side of the second fixing frame 806 is fixedly connected to one side of the connecting plate 804. The output end of the telescopic rod of the second electric push rod 805 is fixedly connected to one side of the clamping plate 807.

[0025] In this embodiment, four groups of plug-in calibration mechanisms 8 are provided, and the four groups of plug-in calibration mechanisms 8 are symmetrically arranged with the mid-perpendicular line of the detection interface 6 as the symmetry axis.

[0026] The plug-in calibration mechanism 8 is used to adjust the contact state between the external connecting line and the detection interface 6. The specific implementation method is as follows: the plug-in calibration mechanism 8 is used to clamp the connection end of the external connecting line and compensate for the insertion force when it is judged that the contact between the external connecting line and the detection interface 6 is incomplete, so as to realize automatic calibration of the plug-in state. One side of the mounting plate 801 is fixedly connected to the shell 2, serving as the mounting base of the entire plug-in calibration mechanism 8, and the other side thereof is fixedly connected to the first electric push rod 802, and one side of the first fixing frame 803 is fixedly connected to the detection interface 6, which plays a role of stable support and positioning guidance; at the same time, the output end of the first electric push rod 802 is fixedly connected to one side of the connecting plate 804, which serves as an intermediate transmission component, and the other side of the connecting plate 804 is fixedly connected to the second electric push rod 805 The second electric push rod 805 is fixedly connected, one end of the telescopic rod is supported and guided by the second fixed frame 806, and the other end is fixedly connected to the clamping plate 807 for clamping the connecting end of the external connecting line; when the central processor 7 determines that the connection is incomplete, the second electric push rod 805 is started, and its telescopic action drives the clamping plate 807 to move forward and clamp the connecting end of the connecting line, and at the same time, the first electric push rod 802 is started synchronously, and drives the entire clamping structure to continue to advance toward the detection interface 6 through the connecting plate 804, thereby realizing stable clamping and insertion force compensation of the external connecting line; in this embodiment, a total of four sets of plug-in calibration mechanisms 8 are arranged symmetrically around the detection interface 6 with the vertical line as the symmetry axis, ensuring uniform clamping and insertion calibration of the external connecting line from multiple directions, thereby improving plug-in stability and contact reliability.

[0027] In this embodiment, the output end of the central processing unit 7 is electrically connected to the input end of the infrared laser emitting module 4, the input end of the signal converter 5, the input end of the first electric push rod 802, and the input end of the second electric push rod 805, respectively, and the output end and input end of the communication quality acquisition module 9 and the output end and input end of the plug-in displacement sensing module 10 are electrically connected to the input end and output end of the central processing unit 7 respectively; It should be noted that electrical connection refers to the process of transmitting electric current from one part of an electronic device or circuit to another part through conductive materials or conductive elements. This connection is a key component of the operation of electronic devices and circuits. It ensures the effective transmission and connection of electron flow in electronic devices. Electrical connection can be made using wires. The electrical connection method between the central processing unit 7 and the infrared laser emitting module 4, the signal converter 5, the first electric push rod 802, the second electric push rod 805, the communication quality acquisition module 9 and the plug-in displacement sensing module 10 is not specifically limited and can be selected according to actual needs.

[0028] In the case of infrared laser modules being used in high-frequency maintenance scenarios such as automated assembly production lines, operators are often required to quickly replace or adjust the modules during equipment operation. At this time, the module is connected to the external signal line by plugging and unplugging through the quick-release detection interface 6. Under such high-frequency, space-constrained, and frequent blind plug-in conditions, incomplete contact between the plug and the socket is prone to occur. Since the existing quick-release structure generally lacks an effective insertion guide mechanism, contact compensation structure, and insertion status confirmation feedback, when the plug is not fully inserted or the insertion direction is skewed, the connection between the module and the external system will be unstable. The existing modular quick-release detection interface infrared laser module cannot effectively avoid such problems as communication failure, signal loss, or false alarm caused by incomplete contact, which in turn leads to abnormal operation of the detection module, disordered control logic, and even misjudgment, shutdown, or product detection errors of the entire system, which seriously affects production efficiency and system stability. Aiming at the problem of plug-in stability caused by frequent replacement and maintenance of infrared laser modules in automated production lines, especially under complex working conditions such as high-frequency plug-in and unplugging, limited space and blind plug-in operations, the traditional quick-release detection interface 6 structure lacks effective insertion guidance, contact compensation and state feedback mechanism, which often leads to incomplete contact between the external connection line and the interface, thereby causing communication failure, signal loss or misjudgment and other faults, seriously affecting the stability and production efficiency of the system operation. Therefore, it is urgent to design a structure that can automatically sense the plug-in status, judge the contact quality in real time and have dynamic correction capabilities to improve connection reliability, reduce failure rate, and reduce manual maintenance intervention, thereby ensuring the long-term stable operation of infrared laser modules in industrial environments, which has important engineering practical value and promotion significance.

[0029] In this embodiment, the error fluctuation index is used to characterize the degree of fluctuation of the error ratio in the communication data over time during the connection process between the external connection line and the detection interface 6. The acquisition method is: the communication quality acquisition module 9 collects the error bit rate data in real time at multiple moments of the connection operation, and calculates the fluctuation range of its deviation from the mean based on the data sequence to form the error fluctuation index. The formula uses an exponential standard deviation model to amplify the error jitter to enhance the sensitivity of abnormal fluctuations. The larger the error fluctuation index, the more unstable the communication signal is during the connection process, and the more drastic the bit error rate changes, indicating that there is a large uncertainty or volatility in the connection contact state, so it can be inferred that there may be incomplete contact or inadequate insertion between the external connection line and the detection interface 6. As one of the core parameters for judging the quality of the connection, this index provides an accurate basis for the control action of the subsequent plug-in calibration mechanism.

[0030] The logic for obtaining the bit error fluctuation index is: S1. The actual number of bit errors in the data transmitted at different times during the connection between the external connection line and the detection interface 6 is obtained through the communication quality acquisition module 9, and marked as , Indicates that during the process of connecting the external connection line to the detection interface 6 The actual number of bit errors in the data being transmitted at any moment, , is a positive integer; S2. Calculate the bit error fluctuation index. The calculation expression is: In the formula, is the bit error fluctuation index.

[0031] In this embodiment, the spacing variation coefficient is used to characterize the degree of fluctuation of the actual spacing between the end face of the connection end and the inner end face of the detection interface relative to the preset spacing during the insertion of the external connection line into the detection interface 6. The acquisition method is as follows: the actual spacing data is collected at multiple moments of the plugging process by the plug displacement sensing module 10, and the central processing unit 7 compares the preset ideal plugging spacing, and then the spacing variation coefficient is calculated by the logarithmic weighted model of the normalized deviation. This coefficient reflects the plugging posture, depth and physical alignment accuracy during the insertion process. The larger the spacing variation coefficient, the more unstable the insertion state, and the more obvious the actual spacing deviates from the preset target, indicating that the connection end may have problems such as insertion angle deviation, insufficient insertion depth or interface misalignment. Therefore, this coefficient can be used as an important basis for judging whether the external connection line and the detection interface 6 have achieved complete and stable contact, and is one of the key parameters for triggering subsequent plug calibration actions.

[0032] The logic for obtaining the spacing variation coefficient is: S1, by inserting the displacement sensing module 10, the actual distance between the end face of the connection end of the external connection line and the inner end face of the detection interface 6 at different times during the process of connecting the external connection line to the detection interface 6 is obtained, and calibrated as , Indicates that during the process of connecting the external connection line to the detection interface 6 The actual distance between the end face of the external connecting line and the inner end face of the detection interface at any time. , is a positive integer; S2, obtaining, by the central processor 7, a preset distance between the end face of the connection end of the external connection line and the inner end face of the detection interface during the process of connecting the external connection line to the detection interface 6, and marking it as ; The central processor 7 obtains the preset spacing between the end face of the connection end of the external connection line and the inner end face of the detection interface 6, which can be achieved in a variety of ways, such as accurately modeling the plug-in structure through three-dimensional modeling software in the module design stage and calculating the theoretical optimal insertion depth, generating a set of static reference spacing parameters, which can be stored in the local storage unit of the central processor 7 as a preset value; or in the initial assembly or factory calibration of the equipment, by using a high-precision distance measuring instrument such as a laser rangefinder or a displacement sensor to measure the actual physical spacing when the connection line is fully inserted, and write the value to the central processor 7 through the interface; in addition, it is also possible to collect multiple continuous readings of the plug-in displacement sensing module 10 and perform mean filtering within a period of time after the plug-in is completed and the signal is completely stable, and then the central processor 7 adaptively sets it to a dynamic preset spacing value. Any of the above methods can enable the central processor 7 to obtain an accurate and reliable reference spacing JJ top as a reference for subsequent real-time spacing fluctuation judgment and spacing variation coefficient calculation. The specific acquisition method is not specifically limited here and can be selected according to actual needs.

[0033] S3. Calculate the spacing variation coefficient. The calculation expression is: In the formula, is the spacing variation coefficient.

[0034] In this embodiment, and After dimensionless processing, the error fluctuation index generated by the central processor 7 is and spacing variation coefficient Conduct comprehensive analysis and generate the judgment coefficient according to the formula: In the formula, is the judgment coefficient, and Bit Error Fluctuation Index and spacing variation coefficient The preset scaling factor of and Both are greater than 0.

[0035] From the calculated expression, we can know that the bit error fluctuation index and spacing variation coefficient The larger the value, the greater the judgment coefficient the bigger it is; It should be noted that dimensionless is a process of expressing physical quantities in dimensionless form. This method can eliminate the influence of units on physical problems, making the problems more concise and universal. and spacing variation coefficient Preset scaling factor and In order to more flexibly adapt to different working conditions and environmental changes in actual monitoring, these preset proportional coefficients can be adjusted according to specific circumstances to improve the performance and applicability of the monitoring system.

[0036] In this embodiment, the preset judgment coefficient reference threshold is set to , the central processor 7 calculates the judgment coefficient and the pre-set reference threshold of the judgment coefficient A comparison is performed, and whether the external connection line is in full contact with the detection interface 6 is determined according to the comparison result, and the working state of the plug-in calibration mechanism 8 is controlled according to the comparison result. The specific determination is as follows: when When the external connection line is in full contact with the detection interface 6, a normal signal is generated. After receiving the normal signal, the central processing unit 7 generates a standby signal and transmits the standby signal to the first electric push rod 802 and the second electric push rod 805 respectively. After receiving the standby signal, the first electric push rod 802 and the second electric push rod 805 control the plug-in calibration mechanism 8 to perform standby work; Standby operation means that, under the premise that the external connection line and the detection interface 6 have been fully contacted and the connection state is stable, the plug-in calibration mechanism 8 is in a stationary and ready-to-execute working state, so as to ensure that the system has the ability to respond to subsequent plug-in abnormalities at any time while maintaining stable contact; its specific implementation method is: after the central processor 7 receives the normal signal generated by the plug-in judgment module, it outputs a standby signal to the first electric push rod 802 and the second electric push rod 805. After receiving the standby signal, the telescopic rod of the first electric push rod 802 remains in the original preset position and no longer moves, and the connecting plate 804 connected to its output end is also in a stable state; in the standby state, the telescopic rod of the second electric push rod 805 remains stationary, and the clamping plate 807 connected to its output end is kept in the original open position without applying clamping force, so as to avoid additional mechanical intervention on the external connection line; during the whole process, the mounting plate 801, the first fixing frame 803, and the second fixing frame 806 are all in a fixed support state, ensuring that the plug-in calibration mechanism 8 is structurally stable and responsive, so that the module is in a low-power, high-responsive stationary working mode in a reliable connection state.

[0037] when When the external connection line is not in complete contact with the detection interface 6, an abnormal signal is generated. After receiving the abnormal signal, the central processing unit 7 generates a calibration signal and transmits the calibration signal to the first electric push rod 802 and the second electric push rod 805 respectively. After receiving the calibration signal, the first electric push rod 802 and the second electric push rod 805 control the plug-in calibration mechanism 8 to perform calibration.

[0038] The calibration work refers to: when the external connection line and the detection interface 6 are not in full contact, the plug-in calibration mechanism 8 actively performs a plug-in compensation and contact correction operation under the control of the central processor 7 to improve the stability and reliability of the connection. The specific implementation method is: when the central processor 7 receives an abnormal signal, it generates a calibration signal and transmits it to the first electric push rod 802 and the second electric push rod 805 respectively; the second electric push rod 805 moves first, and its telescopic rod extends forward, driving the clamping plate 807 fixedly connected to its output end to move outward, and cooperates with the second electric push rod 805 to move outward. The fixed frame 806 forms a support, so that the clamping plate 807 clamps and clamps the connecting end of the external connecting wire, which stabilizes the position of the connecting end and prevents shaking or deflection; then, the first electric push rod 802 is started, and its telescopic rod extends and drives the second electric push rod 805 and the clamping plate 807 to move forward as a whole through the connecting plate 804. Under the connection support of the first fixed frame 803 and one side of the detection interface 6, the axial insertion force of the connecting wire is compensated in the clamping state, so that the connecting end can be more deeply and accurately docked to the inside of the detection interface 6, thereby realizing automatic calibration of the plug-in contact. During the whole process, the mounting plate 801 is the reference support platform, and the various components work together to ensure stable clamping, smooth advancement, and accurate calibration.

[0039] The preset judgment coefficient reference threshold is used as a boundary standard for judging whether the external connection line is in full contact with the detection interface 6, and its value can be determined in the following way: first, in the initial debugging or factory stage of the equipment, multiple groups of typical plug-in states are simulated respectively, including the ideal plug-in state, the insufficient insertion state, the oblique insertion state, the loose contact state, etc., and the error fluctuation index and the spacing variation coefficient are collected simultaneously in each state, and the corresponding judgment coefficient value is calculated to establish a mapping relationship between the state and the judgment coefficient; then, through data statistics and normalization processing, the middle value between the minimum value of the judgment coefficient in the ideal plug-in state and the maximum value of the suboptimal state is selected as the initial reference of the threshold; in some self-learning optimization systems, the central processor 7 can also be combined with the data samples collected for a long time during operation, based on the empirical weight, the principle of minimizing the error rate or machine learning models such as K-means clustering or logistic regression to dynamically fit the optimal threshold range, and store it in the control system as a real-time judgment basis, so as to ensure that the reference threshold is both representative and adaptable and robust, and effectively supports the intelligent judgment process of the plug-in contact state.
