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.

[0004] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present disclosure, and thus it may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0029] Preferably, the preset judgment coefficient reference threshold is set as . The central processing unit compares the calculated judgment coefficient with the preset judgment coefficient reference threshold to judge whether the external connection line and the detection interface are in full contact according to the comparison result, and control the working state of the plug-in calibration mechanism according to the comparison result. The specific judgment is as follows:

[0032] The technical effects and advantages of the present invention are as follows:

[0033] 1.

Compared with the existing structure that completely relies on the passive judgment method of physical plugging position or elastic buckle, the present invention realizes the quantitative identification and intelligent judgment of the plugging state, not only improves the accuracy and sensitivity of judgment, but also avoids communication errors and work abnormalities caused by slight plugging deviation or insufficient insertion.

[0034] 2. When the judgment result shows incomplete contact, the plug-in calibration mechanism set by the present invention immediately responds and starts the double electric push rod structure to realize clamping and insertion force compensation: the second electric push rod drives the clamping plate to clamp the connection line end, and the first electric push rod advances the whole clamping structure towards the detection interface direction through the connection plate, effectively solving the problems of insufficient insertion depth, terminal suspension, mechanical skew, etc. that occur in the traditional quick plug structure under the conditions of high-frequency plugging and unplugging, blind plugging or limited space. The four groups of plug-in calibration mechanisms are symmetrically arranged around the detection interface, further realizing multi-point stable clamping and balanced adjustment of the insertion force, ensuring that the compensation action is fast, reliable and accurate, and improving the mechanical stability and plugging consistency of the connection structure.

[0035] 3. The present invention integrates real-time perception, data calculation, intelligent judgment and mechanical response into a complete closed-loop control system, which has high automation and environmental adaptability, and greatly improves the connection reliability and maintenance efficiency of the infrared laser module in the industrial field. This solution is particularly suitable for high-reliability application scenarios such as automated assembly, high-speed production lines, and dense equipment deployment, can effectively reduce manual debugging intervention, reduce the misjudgment rate and the risk of signal loss, and has significant engineering practical value and industrial promotion potential.

[0047] It further includes:

[0048] The communication quality acquisition module 9 is set at the connection end between the detection interface 6 and the signal converter 5, and is used to obtain in real time the actual number of error bits in the transmitted data at different times during the connection of the external connection line to the detection interface 6, and generate an error code fluctuation index through the central processor 7;

[0051] It should be noted that the plug-in displacement sensing module 10 can be a laser ranging sensor, an optoelectronic sensor, or other devices that can obtain in real time 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 at different times during the connection of the external connection line to the detection interface 6. The plug-in displacement sensing module 10 is not specifically limited here and can be selected according to actual needs.

[0052] The central processor 7 comprehensively analyzes the generated error code fluctuation index and distance change coefficient to judge whether the external connection line is in full contact with the detection interface 6, and controls the working state of the plug-in calibration mechanism 8 according to the comparison result.

[0053] The installation mechanism 3 is used to stably install the entire infrared laser module on the fixed base 1. It can usually be realized by a slide rail snap structure, a screw positioning installation structure or an elastic lock structure to achieve rapid assembly and disassembly of the module; the infrared laser emission module 4 is used to output infrared laser signals, and internally integrates an infrared laser, a collimating lens and a heat dissipation base, which can be fixed in the housing 2 by screws or pressing plates to make it have a stable light emitting direction and heat management ability; the signal converter 5 is used to convert the electrical signals from an external system into control signals recognizable by the infrared laser module, or convert the data collected inside the module into a standard communication format and output it externally, usually realized in the form of a communication interface chip, a level conversion circuit or an embedded microcontroller; the detection interface 6 is used for quick plug connection with external signal lines to realize functions such as power input and signal transceiver. Its structure usually includes conductive jacks, positioning grooves, anti-fooling structures and internal lines connected to the signal converter 5 to ensure the reliability and standardization of external connections. This structural system jointly constitutes the basic function support and external adaptation mechanism of the infrared laser module.

[0054] 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 housing 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. 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. 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. 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.

[0055] 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 perpendicular bisector of the detection interface 6 as the axis of symmetry.

[0056] The plug-in calibration mechanism 8 is used to adjust the contact state between the external connection line and the detection interface 6. The specific implementation method is as follows: The plug-in calibration mechanism 8 is used to clamp and compensate the insertion force of the connection end of the external connection line when it is judged that the contact between the external connection line and the detection interface 6 is incomplete, so as to realize the automatic calibration of the plug-in state. One side of the mounting plate 801 is fixedly connected to the housing 2 and serves as the mounting base of the entire plug-in calibration mechanism 8. The other side is fixedly connected to the first electric push rod 802. One side of the first fixing frame 803 is fixedly connected to the detection interface 6, playing 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, serving as an intermediate transmission component. The other side of the connecting plate 804 is fixedly connected to the second electric push rod 805. One end of the telescopic rod of the second electric push rod 805 is supported and guided by the second fixing frame 806, and the other end is fixedly connected to the clamping plate 807 for clamping the connection end of the external connection line. When the central processor 7 judges that the connection is incomplete, the second electric push rod 805 is started. Its telescopic movement drives the clamping plate 807 to move forward to clamp the connection end of the connection line. At the same time, the first electric push rod 802 is started synchronously, and the entire clamping structure is driven through the connecting plate 804 to continue to advance in the direction of the detection interface 6, so as to realize the stable clamping and insertion force compensation of the external connection line. In this embodiment, a total of four groups of plug-in calibration mechanisms 8 are provided, which are symmetrically arranged around the detection interface 6 with its perpendicular bisector as the axis of symmetry, ensuring uniform clamping and insertion calibration of the external connection line from multiple directions, and improving the plug-in stability and contact reliability.

[0057] In this embodiment, the output end of the central processor 7 is electrically connected to the input end of the infrared laser emission 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. The output end and the input end of the communication quality acquisition module 9 and the output end and the input end of the plug-in displacement sensing module 10 are electrically connected to the input end and the output end of the central processor 7 respectively.

[0058] It should be noted that electrical connection refers to the process of transmitting current from one part of an electronic device or circuit to another part through conductive materials or conductive components. This connection is a key component for the operation of electronic devices and circuits. It ensures the effective transmission and connection of the electronic current in the electronic device. Electrical connection can be carried out by using wires. The specific connection method between the central processor 7 and the infrared laser emission 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.

[0059] 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.

[0060] 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.

[0061] The logic for obtaining the bit error fluctuation index is:

[0062] S1. Obtain the actual number of error bits in the transmitted data at different times during the connection of the external connection line to the detection interface 6 through the communication quality acquisition module 9, and calibrate it as , which represents the actual number of error bits in the transmitted data at time during the connection of the external connection line to the detection interface 6, , where

[0063] is a positive integer;

[0063] S2. Calculate the error fluctuation index, and the calculation formula is:

[0064]

[0065] In the formula, is the error fluctuation index.

[0066] In this embodiment, the spacing change coefficient is used to characterize the fluctuation degree 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: collect the actual spacing data at multiple times during the insertion process through the insertion displacement sensing module 10, and the central processor 7 compares it with the preset ideal insertion spacing, and then calculates the spacing change coefficient through the logarithmic weighted model of the normalized deviation. This coefficient reflects the insertion attitude, depth and physical alignment accuracy during the insertion process. The larger the spacing change coefficient, the more unstable the insertion state, and the more obvious the deviation of the actual spacing from the preset target, indicating that there may be problems such as skewed insertion angle, insufficient insertion depth or misalignment of the interface at the connection end. Therefore, this coefficient can be used as an important basis for judging whether the external connection line and the detection interface 6 achieve complete and stable contact, and is one of the key parameters to trigger subsequent insertion calibration actions.

[0067] The acquisition logic of the spacing change coefficient is as follows:

[0068] S1. Obtain the actual spacing between the end face of the connection end of the external connection line and the inner end face of the detection interface at different times during the connection of the external connection line to the detection interface 6 through the insertion displacement sensing module 10, and calibrate it as , which represents the actual spacing between the end face of the connection end of the external connection line and the inner end face of the detection interface at time during the connection of the external connection line to the detection interface 6, , where

[0069] is a positive integer;

[0069] S2. Obtain 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 during the connection of the external connection line to the detection interface 6 through the central processor 7, and calibrate it as ;

[0070] The central processing unit 7 can obtain the preset distance between the end face of the connection end of the external connection line and the inner end face of the detection interface 6 in various ways. For example, during the module design stage, precise modeling of the plugging structure is carried out through 3D modeling software, and the theoretical optimal insertion depth is calculated to generate a set of static reference distance parameters, which can be stored in the local storage unit of the central processing unit 7 as preset values; or during the initial assembly or factory calibration of the device, the actual physical distance in the fully inserted state of the connection line is measured by using a high-precision distance measuring instrument such as a laser rangefinder or a displacement sensor, and this value is written into the central processing unit 7 through the interface; in addition, after the plugging is completed and within a period of time when the signal is completely stable, multiple consecutive readings of the plugging displacement sensing module 10 are collected and mean filtering is performed, and then the central processing unit 7 adaptively sets it as the dynamic preset distance value. Any of the above methods can enable the central processing unit 7 to obtain an accurate and reliable reference distance JJ top, which is used as the reference basis for subsequent real-time distance fluctuation judgment and distance change coefficient calculation. The specific acquisition method is not specifically limited here and can be selected according to actual needs.

[0071] S3. Calculate the distance change coefficient, and the calculation expression is:

[0072]

[0073] In the formula, is the distance change coefficient.

[0074] In this embodiment, after and are dimensionless processed, the central processing unit 7 comprehensively analyzes the generated error code fluctuation index and the distance change coefficient to generate a judgment coefficient, based on the formula:

[0075]

[0076] In the formula, is the judgment coefficient, and are respectively the preset proportional coefficients of the error code fluctuation index and the distance change coefficient , and and are both greater than 0.

[0077] It can be seen from the calculation expression that the larger the error code fluctuation index and the distance change coefficient are, the larger the judgment coefficient will be;

[0078] It should be noted that non - dimensionalization is a process of expressing physical quantities in a non - dimensional form. In this way, the influence of units on physical problems can be eliminated, making the problems more concise and general; the error code fluctuation index and the pitch change coefficient of the preset proportionality coefficients and are for more flexibly adapting to different working conditions and environmental changes in actual monitoring. These preset proportionality coefficients can be adjusted according to specific situations to improve the performance and applicability of the monitoring system.

[0079] In this embodiment, the preset judgment coefficient reference threshold is set to , and the calculated judgment coefficient is compared with the preset judgment coefficient reference threshold by the central processor 7. According to the comparison result, it is judged whether there is full contact between the external connection line and the detection interface 6, and the working state of the plug - in calibration mechanism 8 is controlled according to the comparison result. The specific judgment is as follows:

[0080] When , there is full contact between the external connection line and the detection interface 6, and a normal signal is generated. After receiving the normal signal, the central processor 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;

[0081] Standby work means that on the premise that the full contact between the external connection line and the detection interface 6 has been completed and the connection state is stable, the plug - in calibration mechanism 8 is in a working state of remaining stationary and ready to execute, so as to ensure that the system has the ability to respond to subsequent plug - in abnormalities at any time while maintaining stable contact. The specific implementation method is as follows: after receiving the normal signal generated by the plug - in judgment module, the central processor 7 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 at the original preset position and does not move, 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 remains at the original opening position without applying a clamping force to avoid additional mechanical interference to the external connection line; during the whole process, the mounting plate 801, the first fixing bracket 803, and the second fixing bracket 806 are all in a fixed support state, ensuring that the plug - in calibration mechanism 8 has a stable structure and is ready to respond, so that the module is in a low - power - consumption and high - responsiveness stationary working mode under a reliable connection state.

[0082] When When the external connection line is not in full 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 work.

[0083] The calibration work refers to: when the external connection line is not in a fully contacted state with the detection interface 6, a plug-in compensation and contact correction operation actively performed by the plug-in calibration mechanism 8 under the control of the central processing unit 7, which is used to improve the stability and reliability of the connection. The specific implementation method is as follows: when the central processing unit 7 receives the 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 acts first, and its telescopic rod extends forward, driving the clamping plate 807 fixedly connected to its output end to move outward, and cooperating with the second fixing frame 806 to form a support, so that the clamping plate 807 clamps and tightens the connection end of the external connection line, playing a role in stabilizing the position of the connection end and preventing shaking or deflection; subsequently, the first electric push rod 802 starts, its telescopic rod extends and drives the second electric push rod 805 and the clamping plate 807 as a whole to advance forward through the connecting plate 804. Under the connection support on one side of the first fixing frame 803 and the detection interface 6, the axial insertion force compensation of the connection line in the clamped state is realized, so that the connection end can be inserted more deeply and accurately into the detection interface 6, thereby realizing the automatic calibration of the plug-in contact. During the whole process, the mounting plate 801 is the reference support platform, and each component cooperates to ensure stable clamping, smooth advancement and accurate calibration.

[0084] The preset judgment coefficient reference threshold is used as the 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, during the initial debugging or factory stage of the equipment, multiple groups of typical plug-in states are simulated respectively, including ideal plug-in state, insufficient insertion state, oblique insertion state, contact loosening state, etc. Under each state, the error code fluctuation index and the spacing change coefficient are collected simultaneously, and the corresponding judgment coefficient value is calculated to establish the mapping relationship between the state and the judgment coefficient; then, through data statistics and normalization processing, the intermediate value between the minimum value of the judgment coefficient in the ideal plug-in state and the maximum value of the sub-optimal state is selected as the initial reference of the threshold; in some self-learning optimization systems, the central processing unit 7 can also combine the long-term collected data samples during operation, and dynamically fit the optimal threshold range based on the empirical weight, the principle of minimizing the misjudgment rate or machine learning models such as K-means clustering or logistic regression, and store it in the control system as the real-time judgment basis, so as to ensure that the reference threshold is both representative, adaptable and robust, and effectively support the intelligent judgment process of the plug-in contact state.
