Description

Technical Field

[0001] The utility model relates to the technical field of parking locks, and in particular to an intelligent ground lock. Background Art

[0002] With the rapid development of modern automation and intelligent technology, the requirements for precise control and status monitoring of various mechanical devices are increasing, especially in the field of safety protection, such as the automatic control and status feedback of vehicle anti-theft ground lock systems. Traditional ground lock systems often rely on simple mechanical structures and manual operations, which are not only inconvenient to operate, but also have limitations in precise control and status judgment. Traditional monitoring and control methods face several challenges.

[0003] These problems mainly focus on accuracy, real-time performance, and sensitivity to changes in mechanical loads. In the current state of the art, traditional mechanical position detection technologies, such as limit switches and mechanical contacts, often rely on physical contact, which is not only prone to wear, but also has limited detection accuracy and is difficult to meet the needs of high-precision positioning. Especially in continuous and frequent motion control, mechanical wear may lead to the accumulation of position detection errors, affecting system performance and life. For systems that need to adjust power output according to load changes, such as the lifting control of ground locks, existing monitoring methods often lack sensitivity to subtle changes in load. Relying solely on the fixed program control of the motor, it is impossible to accurately judge the tightness of the steel cable in real time, which in turn affects the efficiency and safety of the ground lock operation. In some cases, excessive loads may cause the motor to overheat or damage, while too light loads may cause energy waste. In automation applications, the lack of intelligent feedback and adaptive control mechanisms makes it difficult for the system to dynamically adjust according to the actual working state, affecting the response speed and efficiency of the system. For example, the required driving force of the ground lock will change under different ground conditions or usage cycles, and traditional control methods are difficult to effectively cope with.

[0004] Therefore, there is an urgent need for an intelligent ground lock to improve the accuracy and reliability of position detection, and at the same time indirectly judge the working status of the ground lock through changes in current and voltage, thereby improving the intelligence level and operating efficiency of the system. Utility Model Content

[0019] Furthermore, the code disk detection unit includes symmetrically arranged photoelectric tubes.

[0020] Furthermore, the rotation angle of the code disk can be used to derive the position and motion state of the drive unit.

[0036] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The utility model provides an intelligent ground lock. Figure 1 As shown, the lock frame 1, the ground lock body 2 and the detection module 3 together constitute a set of efficient and safe vehicle parking management solutions.

[0038] The lock frame 1 is made of high-quality steel or high-strength composite materials, which not only ensures a firm connection with the ground, but also can withstand the pressure of frequent vehicle entry and exit in daily life, and can also resist erosion by external environmental factors such as rain, wind and sand, thereby ensuring the long-term stability and durability of the ground lock.

[0039] The ground lock body 2 is installed inside the lock frame 1 and is the technical core of the entire system. The ground lock body 2 is used to receive control signals to switch between the horizontal state and the tilted state, thereby effectively opening or closing the parking space. While performing the operation, the sensor inside the ground lock body 2 will generate a motor feedback signal, which contains the current working status information of the ground lock and is the basis for realizing intelligent monitoring.

[0040] The detection module 3 is arranged on the ground lock body 2, and the detection module 3 is connected to the ground lock body 2, and is used to generate a code disk detection signal according to the received motor feedback signal, and accurately capture the tiny rotation of the code disk in the ground lock body 2 through the built-in code disk detection unit 31, and convert these physical actions into high-precision code disk detection signals, so as to monitor the precise position and movement trajectory of the ground lock in real time. The equipped voltage detection unit 32 can continuously monitor the working voltage of the motor unit 22, capture voltage fluctuations and convert them into voltage detection signals. This design can not only reflect the load condition of the motor, but also indirectly judge the tension of the steel cable, providing valuable real-time data for the working status evaluation and fault warning of the ground lock.

[0041] In summary, this intelligent ground lock system, through its highly integrated design, not only achieves effective control of parking spaces, but also ensures stable operation and efficient maintenance of the system through precise detection modules 3, bringing innovation to the field of intelligent parking management and improving user experience and management efficiency.

[0042] Specifically, the ground lock body 2 includes a drive unit 21 and a motor unit 22, which work together to ensure accurate and efficient operation of the ground lock. The drive unit 21 is located in the middle of the smart ground lock. It is made of high-strength alloy material and includes a set of precise gear transmission mechanisms and a sturdy locking mechanism, which is used to execute the instructions of the smart ground lock to allow or prohibit vehicles from entering the corresponding parking space.

[0043] The motor unit 22 is located at the rear of the ground lock body 2. It uses a high-performance DC motor, which stands out for its high torque, low power consumption and fast response. The motor unit 22 has an advanced closed-loop control system built in, which can receive command signals from the intelligent control center in real time and respond quickly. After these control signals are decoded and processed, the motor immediately outputs the corresponding power to accurately control the speed and strength of the drive unit 21.

[0044] In addition, the motor unit 22 and the drive unit 21 are connected by a highly durable flexible coupling. This design not only ensures the smoothness of power transmission, but also absorbs vibrations during operation to a certain extent, reduces system noise, and improves overall operational smoothness and user-friendliness. In short, this carefully designed ground lock body 2 structure has become an indispensable key component in the intelligent parking management system through its efficient and stable performance.

[0045] Specifically, the driving unit 21 includes a steel cable 211 and a code disc 212. Figure 2-Figure 4As shown, the steel cable 211 is connected to the code disc 212 by transmission. The drive unit 21 is the power transmission core in the intelligent ground lock system. Its internal structure mainly includes the steel cable 211 and the code disc 212. The two are closely combined through a precise transmission connection mechanism and work together to achieve precise control and efficient operation of the ground lock. The steel cable 211 is made of high-strength, wear-resistant special steel wire rope to ensure that it can maintain good toughness and durability under frequent stretching and torsion operations. One end of the steel cable 211 is fixed to the output shaft of the motor unit 22, and the other end is connected to the mechanical transmission mechanism of the ground lock body 2, such as the ground lock arm or baffle, which is converted into the actual lifting action of the ground lock through the linear or rotational motion generated by the motor drive. The diameter and material of the steel cable are carefully selected to balance the load-bearing capacity, movement flexibility and stability under long-term use.

[0046] The code disc 212, as a key component of position feedback, is installed inside the drive unit 21 and is directly connected to the steel cable 211. The code disc is usually made of wear-resistant material, and circles of optical or magnetic coding tracks are evenly distributed on the surface. These coding tracks have different marks or magnetic polarities at different positions. As the steel cable moves, the code disc rotates accordingly. The design of the coding track is very precise, and it can record the tiny displacement of the ground lock body 2 with extremely high resolution, ensuring high precision of position detection. The transmission connection part adopts a precision ball bearing or gear rack mechanism to ensure that the tension or thrust of the steel cable can be smoothly and losslessly transmitted to the code disc, while reducing friction loss and noise during movement. This design not only improves the response speed of the system, but also extends the service life of the components. In addition, in order to further improve the stability and reliability of the system, a lubrication system and a dustproof seal design can be added to the transmission connection part to meet the working requirements in different environments.

[0047] In summary, the steel cable 211 and the code disc 212 in the driving unit 21 realize efficient power transmission and accurate position feedback through a highly integrated and precisely adjusted transmission connection mechanism, which is the key to the precise control and stable operation of the smart ground lock.

[0048] Specifically, Figure 3 and Figure 4As shown, the detection module 3 includes a code disc detection unit 31 and a voltage detection unit 32, which ensures real-time monitoring and precise control of the operating state of the ground lock. Among them, the code disc detection unit 31 is arranged on both sides of the code disc, which is used to detect the rotation angle of the code disc and generate a code disc detection signal. Through the high-speed signal processing circuit, the system can judge the current position and action state of the ground lock in real time, ensuring the execution accuracy and response speed of the control instruction. The voltage detection unit 32 is arranged on the rear side of the code disc 212, which is used to detect the load voltage of the motor unit 22 and generate a load voltage detection signal. Specifically, when the motor unit 22 drives the ground lock body 2 to move, the change of its load will be directly reflected in the fluctuation of the power supply voltage. The voltage detection unit 32 continuously samples the power supply voltage of the motor, and can quickly identify and quantify this change even in a slight stall state caused by a change in the tension of the steel cable, and convert it into a load voltage detection signal. These signals are crucial for evaluating the motor workload and predicting potential mechanical jams or overloads, and provide key data support for the fault warning and self-protection mechanism of the intelligent ground lock.

[0049] In summary, the detection module 3 realizes all-round and high-precision monitoring of the working status of the intelligent ground lock through the close cooperation of the code disk detection unit 31 and the voltage detection unit 32, which not only improves the system's automation control level, but also enhances the system's stability and security, ensuring that the intelligent ground lock can serve modern parking management needs efficiently and reliably in the long term.

[0050] Specifically, the voltage detection unit 32 includes an ADC sensor; the code disk detection unit 31 includes symmetrically arranged photoelectric tubes.

[0051] The core component of the voltage detection unit 32 is a high-performance analog-to-digital converter (ADC) sensor, which is used to accurately measure the real-time load voltage of the motor unit 22 under different working conditions. The ADC sensor can convert the continuously changing analog voltage signal into a digital signal through high-resolution sampling technology. It is directly connected to the power circuit of the motor to ensure that the collected data can instantly reflect the actual working pressure of the motor.

[0052] The code disk detection unit 31 uses two groups of symmetrically arranged photoelectric tubes, which are embedded in fixed positions on both sides of the code disk. The surface of the code disk is covered with evenly spaced transparent and opaque areas. As the code disk rotates with the motor, these areas alternately block and release the photoelectric tubes, and the resulting sequence of light pulses is converted into electrical signals. Each group of photoelectric tubes is equipped with a precision optical lens and a highly sensitive photoelectric receiving element to ensure fast and reliable signal conversion under various lighting conditions. In summary, the voltage detection unit 32 and the code disk detection unit 31 jointly construct a highly sensitive, stable and reliable detection system by integrating sensor technology and sophisticated signal processing methods, which provides strong technical support for the precise positioning, efficient operation and safety monitoring of the intelligent ground lock.

[0053] Specifically, the rotation angle of the code disk can be used to determine the position and motion state of the drive unit 21. As a key sensing component in the intelligent floor lock system, the code disk can provide real-time feedback on the precise position and dynamic motion state of the drive unit 21 through precise measurement of the rotation angle. Specifically, the surface of the code disk is covered with equally spaced coding marks, which interact with the photoelectric tubes in the code disk detection unit 31 to generate precise signals. The code disk and the drive unit 21 are closely matched through mechanical connection. When the motor unit 22 receives a control signal to drive the floor lock body 2 to switch between the horizontal and tilted states, the code disk rotates accordingly. The tiny displacements during this rotation process are captured by the symmetrically arranged photoelectric tubes and converted into electrical signals. These signals carry the exact angle information of the code disk rotation. By analyzing and calculating these signals, the control system can instantly understand the current position information of the floor lock, such as whether the floor lock is fully open, closed, or in a transition state.

[0054] Furthermore, by continuously monitoring the rate of change of the angle of rotation of the code disk, the movement speed and acceleration of the drive unit 21 can be calculated, which is crucial for predicting the completion time of the ground lock action, monitoring the smoothness of the movement process, and evaluating the working efficiency of the entire system. For example, if the rotation speed of the code disk changes suddenly, it may mean that the ground lock encounters resistance or is about to reach a predetermined position. The control system can adjust the power output of the motor in a timely manner based on this information to ensure smooth movement and avoid impact or unnecessary energy consumption. In short, the rotation angle of the code disk not only directly maps the physical position of the drive unit 21, but also indirectly reveals its dynamic behavior, providing solid data support for the precise control, fault diagnosis and performance optimization of the smart ground lock, and is one of the core technologies to ensure the efficient and stable operation of the smart ground lock system.

[0055] Among them, the load voltage is an important indicator parameter of the motor working state, and its change trend is directly related to the tension state of the steel cable. The tightness of the steel cable can be judged, so as to obtain whether the drive unit 21 is in the lifting process or the laying process. Specifically, when the intelligent ground lock performs an operation, when the motor unit 22 drives the steel cable 211 to move according to the control signal, the load borne by the motor unit 22 will change with the stress state of the steel cable 211. When the ground lock switches from a horizontal state to a tilted state (i.e., the lifting process), the steel cable needs to overcome the gravity and possible friction of the ground lock body 2 and rise upward. At this time, the motor unit 22 needs to output a larger torque to pull the steel cable 211, resulting in an increase in the load of the motor unit 22 and an increase in the load voltage.

[0056] On the contrary, when the ground lock returns from the tilted state to the horizontal state (i.e., the laying process), gravity often helps the steel cable 211 to fall naturally, and the motor unit 22 only needs to provide a small force to control the falling speed or maintain the stability of the slow laying. At this time, the load of the motor unit 22 is lighter, the current consumption is reduced, and the load voltage will decrease compared to the pulling process, showing a lower value. By real-time monitoring of the load voltage of the motor unit 22, the control logic in the system can instantly identify the change in the tightness of the steel cable, and then judge the working stage of the drive unit 21. For example, when the load voltage exceeds the preset high threshold, the system can determine that the ground lock is in a pulling process that requires more energy output; and when the voltage drops to near the low threshold, it indicates that the ground lock is being laid down or is in a relaxed state without load. This judgment mechanism based on voltage changes can not only achieve precise control of the ground lock action, but also effectively prevent motor overload, protect the motor from damage, and ensure the long-term stable and safe operation of the intelligent ground lock system.

[0057] Specifically, it also includes a status display module 4. Figure 1 As shown, the status display module 4 is arranged above the ground lock body 2 and runs through the front side of the lock frame, and is used to receive signals from the code disk detection unit 31 and the voltage detection unit 32 in real time, and convert these complex electronic signals into intuitive status information that is easy to understand and directly visible to the operator through advanced signal processing algorithms. The code disk detection signal and the voltage detection signal are received to display the status information of the smart ground lock.

[0058] The code disk detection signal carries the current precise position information of the ground lock, including whether it is fully open, fully closed, or in an intermediate state of motion. The voltage detection signal reflects the workload of the motor unit 22, and indirectly indicates the tension state of the steel cable 211, that is, whether the ground lock drive unit 21 is performing a lifting operation or a laying down operation. The status display module 4 is integrated with a high-resolution LED display or LCD screen, which clearly displays the key information such as the working mode, locking status, abnormal warning, etc. of the ground lock in various forms such as numbers, graphics or color coding.

[0059] In summary, this design not only enhances the user interaction experience of the smart ground lock, but also ensures the transparent management of the system status. It is an important part of realizing the efficient operation of smart parking management.

[0060] Specifically, the status display module 4 also includes an alarm unit 41, which is used to give an alarm when the code disk detection signal and the voltage detection signal exceed the set threshold. The alarm unit 41 is closely integrated with the status display module 4, and by real-time monitoring of the code disk detection signal and the voltage detection signal, when these signals exceed the preset safety threshold, the alarm mechanism can be immediately activated to promptly notify the management personnel to pay attention to potential problems or emergencies.

[0061] Specifically, the abnormality of the code disk detection signal usually indicates that the ground lock may have problems such as position deviation or mechanical jamming during operation. For example, when the code disk rotates abnormally fast or slow, which is inconsistent with the expected ground lock action, the alarm unit 41 will respond to this deviation and send an audible and visual alarm to remind you to check whether the ground lock executes the instruction correctly or whether there is any external obstruction. As for the voltage detection signal, if it exceeds the set high threshold, it may mean that the motor is overloaded, and long-term operation will increase the risk of motor damage; if it is lower than the low threshold, it may indicate that the battery is low or the power supply is unstable, affecting the normal operation of the ground lock. The alarm unit 41 can accurately identify these two situations, and ensure that the problem is paid attention to and handled in time through beeps, flashing warning lights or directly sending remote notifications to the manager's mobile phone or control center. Through the design of the status display module 4 with the integrated alarm unit 41, the intelligent ground lock can not only display the working status in real time, but also actively warn of potential risks, effectively prevent the expansion of faults, and ensure the efficiency and safety of parking lot management.

[0062] like Figure 5As shown, when the intelligent ground lock is working, the external control system sends a control signal. After the ground lock body 2 receives it, the motor unit 22 drives the steel cable 211, and the steel cable drives the code disk to rotate to realize the physical action of the ground lock. The rotation of the code disk is converted into a code disk detection signal by the photoelectric tube, providing accurate position feedback. The voltage change when the motor is working is detected by the ADC sensor, reflecting the tension state of the steel cable, and further judging the movement state of the ground lock. All detected signals are summarized in the status display module 4, which displays the status of the ground lock in real time. In case of abnormal situation, the alarm unit 41 is activated to form a closed-loop monitoring and feedback system to ensure the normal operation and safe use of the ground lock.
