Technical Field

[0001] This utility model belongs to the field of alarm device technology, and in particular relates to an overcrowding alarm device for a workshop. Background Technology

[0002] In existing technologies, commonly used personnel identification and detection systems mainly include camera-based identification systems and infrared sensing systems. Camera-based personnel identification systems typically rely on high-resolution cameras and complex image processing algorithms to identify personnel or detect their activity by analyzing captured images. Although such systems offer high accuracy, they are relatively expensive and usually require specialized installation and debugging, increasing the complexity of use. Furthermore, camera-based identification systems present potential privacy protection issues because image data needs to be stored and processed.

[0003] Infrared sensing systems detect human body temperature or movement using infrared sensors to achieve personnel detection. While infrared sensing systems have the advantages of simple structure and fast response, their identification capabilities are relatively limited. They typically cannot accurately distinguish the identity of a person, only providing information on the presence or absence of a person. Furthermore, infrared sensors are limited in detection distance and environmental adaptability, and may be affected by temperature changes and obstacles, thus impacting detection accuracy.

[0004] In summary, the shortcomings of existing technologies are: camera recognition systems are costly, complex to install, and difficult to guarantee privacy protection, while infrared sensing systems, although relatively low in cost, have limited recognition capabilities and poor adaptability.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0033] This utility model embodiment provides a workshop overcrowding alarm device, see reference. Figures 1-4As shown, the workshop overcrowding alarm device includes a counting module 1, a transmission module 2, and an alarm module 3. The counting module 1 includes a rotary button 101, a counting display screen 102, and a first slider 103. The rotary button 101 is used to record the number of people in the workshop, the counting display screen 102 is used to display the current number of people, and the first slider 103 moves horizontally on the counting display screen 102 to intuitively indicate the current number of people in the workshop. The transmission module 2 is connected to the counting module 1 and includes a gear assembly 201, a rack 202, and a second slider 203. The rotary button 101 is connected to the rack 202 through the gear assembly 201. When the rotary button 101 is rotated, the gear assembly 201 drives the rack 202 to move horizontally. The movement of the rack 202 drives the second slider 203 to move synchronously. The second slider 203 drives the first slider 103 to move through mechanical linkage, thereby reflecting the change in the number of people in real time. The alarm module 3 consists of a contact piece 301 and a warning light 302. When the number of personnel reaches the preset upper limit, the second slider 203 moves to the position of the contact piece 301 to close the circuit, triggering the warning light 302 to illuminate, indicating that the workshop is overcrowded. This invention adjusts the number of personnel by rotating the button 101. When personnel enter or leave the workshop, the operator can rotate the button 101 to increase or decrease the number of personnel. The action of rotating the button 101 is converted into linear motion of the rack 202 through the gear assembly 201, which in turn drives the second slider 203 to move synchronously, so that the number of personnel on the counting display screen 102 and the position of the first slider 103 reflect the number of personnel in real time. If the number of personnel reaches the preset overcrowding limit, the second slider 203 contacts the contact piece 301, closing the circuit and triggering the warning light 302, ensuring timely reminders of overcrowding. This device is simple in design, easy to operate, and can accurately record and display the number of personnel in the workshop. Its alarm function can promptly remind users of overcrowding through the warning light, preventing safety hazards caused by overcrowding and improving the safety management level of the workshop.

[0034] In some embodiments, different sliders, gear assemblies 201, or displays can be replaced as needed. For example, a higher-precision electronic display can be used instead of a mechanical counting display, or a more complex gear design can be applied in the transmission module 2 to accommodate workshops of different sizes. The position of the contact piece 301 in the alarm module 3 can also be flexibly adjusted to accommodate different overload threshold requirements.

[0035] Furthermore, the rotary button 101 has increment and decrement functions. Clockwise rotation of the rotary button 101 increases the recorded number of people in the workshop, while counter-clockwise rotation decreases the recorded number; these increment and decrement functions are achieved through different rotation directions. Clockwise rotation causes the gear assembly 201 to drive the rack 202 and the second slider 203 in the increment direction, reflecting an increase in the number of people; counter-clockwise rotation causes the rack 202 and the second slider 203 to move in the decrement direction, visually decreasing the displayed number of people. This design simplifies the personnel counting process, is easy to operate and responds quickly, avoids the tedious process of manually entering data, and improves the efficiency of data updates.

[0036] In some embodiments, the rotary button 101 can be replaced with other types of operating switches, such as push-button type increase / decrease buttons, or the increase / decrease function can be realized through a digital sensor to meet the needs of different usage environments.

[0037] In some embodiments, the rotary button 101 has scale lines. Each rotation of one scale line represents the gear assembly 201 driving the second slider 203 to move one unit in a set direction. This unit movement indicates a change in the number of people in the workshop: each forward scale line indicates an increase of one person in the workshop; each backward scale line indicates a decrease of one person in the workshop. This design provides a convenient and intuitive way to adjust the number of people, allowing for simple recording or modification of the number of people in the workshop by manually rotating the button 101.

[0038] Furthermore, the gear assembly 201 includes two large gears 2011 and a small gear 2012. The small gear 2012 is located between and meshes with the two large gears 2011. The rotary button 101 is connected to the corresponding large gear 2011 via the rotating shaft 4. Through the coordinated transmission of the large and small gears, the rotation of the rotary button 101 drives the small gear 2012 to mesh with the two large gears 2011, forming a stable transmission effect, thereby improving the accuracy and stability of the gear transmission. The design of the gear assembly 201 ensures the accurate transmission of changes in the number of personnel, reduces transmission errors, and enhances the stability and service life of the system.

[0039] In some embodiments, the configuration of the gear assembly 201 can be adjusted as needed; for example, the pinion 2012 can be replaced with a multi-ratio gear or a gear with a smaller module to obtain different transmission ratios and accuracies.

[0040] Furthermore, the first slider 103 is slidably disposed on the counting display screen 102 so as to move horizontally on the counting display screen 102 to indicate the current number of people in the workshop; by sliding on the counting display screen 102, the first slider 103 is synchronized with the change in the number of people, making the indication of the number of people more intuitive. The setting of the first slider 103 makes it easy for the operator to directly observe the number of people, intuitively displaying the dynamics of people in the workshop and improving the readability of information.

[0041] Furthermore, the rack 202 is fixedly connected to the second slider 203. When the rotary button 101 drives the gear assembly 201 to rotate, the gear assembly 201 drives the rack 202 and the second slider 203 to move horizontally. The fixed connection between the rack 202 and the second slider 203 enables the rotary button 101 to move synchronously with the numerical indicator device. This design ensures the smoothness of the counting process and the reliability of the transmission, preventing misalignment between the second slider 203 and the rack 202.

[0042] In some embodiments, the connection between the rack 202 and the second slider 203 can be achieved by different fixing methods, such as snap-fit ​​or adhesive bonding, to meet different installation conditions and usage requirements.

[0043] Furthermore, contact piece 301 is positioned at the end of the movement path of the second slider 203. When the second slider 203 moves to this position, it contacts contact piece 301 to close the circuit, thereby triggering the warning light 302 to illuminate. When the number of personnel reaches the set upper limit, rotating button 101 drives rack 202 and the second slider 203 to move, causing the second slider 203 to contact contact piece 301 at a preset position. After contact piece 301 contacts the second slider 203, the circuit is closed, triggering the warning light 302 in alarm module 3 to illuminate, indicating that the workshop is overcrowded. By setting contact piece 301 at the end of the path of the second slider 203, precise control of circuit closure is achieved, timely and accurate overcrowding warnings are issued, and the problem of overcrowding in the workshop is effectively avoided.

[0044] Furthermore, a warning light 302 is mounted on the counting display screen 102 and connected to the circuit of the alarm module 3. When the second slider 203 moves to the preset upper limit position and triggers the contact piece 301, the circuit closes to illuminate the warning light. The warning light 302 is located in a prominent position on the counting display screen 102 and is connected to the circuit of the alarm module 3. When the number of personnel reaches a set value, the contact piece 301 is triggered to close the circuit, and the warning light 302 illuminates, reminding workshop managers to take appropriate measures. This setup allows operators to promptly observe overcrowding warnings, reducing safety risks. It also allows for centralized information display, simplifies the layout of the warning system, and enhances the overall aesthetics and user experience of the device.

[0045] In some embodiments, the color, position, and display method of the warning light 302 can be adjusted according to the environmental requirements of different workshops, or replaced with a higher brightness LED light to improve the warning effect and adapt to low light environments or special needs.

[0046] Furthermore, the counting display screen 102 is a digital display screen that directly shows the current number of people in the workshop, facilitating real-time monitoring by operators. The digital display screen shows the number of people in the workshop in real time, allowing operators to obtain information intuitively without the need for manual counting or calculation, thus improving the efficiency and accuracy of monitoring. The direct display of the number of people on the digital display screen allows operators to keep track of the personnel dynamics in the workshop at any time, improving operational convenience and the clarity of data reading.

[0047] Furthermore, alarm module 3 also includes a buzzer, which emits an audible warning signal when the circuit is closed. When the number of personnel reaches the overcrowding limit, the buzzer is triggered simultaneously with the circuit closure, emitting an audible warning signal. This audible signal enhances the warning effect, allowing managers to be aware of overcrowding through hearing, in addition to visual warning. The addition of the buzzer enhances the alarm device's alerting function, providing an alternative warning method, especially when the operator cannot see the warning light 302, thus improving the practicality and versatility of the alarm device.

[0048] Furthermore, the position of the contact piece 301 is adjustable to set different overcrowding thresholds as needed. By adjusting the position of the contact piece 301, different overcrowding thresholds can be flexibly set. For example, by moving the contact piece 301 to the left or right, the upper limit of the overcrowding limit can be increased or decreased to adapt to different workshop capacities or scenario requirements. The adjustable position of the contact piece 301 enables the alarm device to adapt to different workshop capacity requirements, improving the adaptability and usability of the alarm device and providing flexibility for overcrowding monitoring in different scenarios.

[0049] The working process of the above-mentioned workshop overcrowding alarm device is as follows:

[0050] Operators record personnel entry and exit within the workshop by rotating button 101. Rotating button 101 drives the second slider 203 in transmission module 2 to move synchronously, updating the personnel count on the counting display screen 102 in real time. When the number of people reaches a preset upper limit, the second slider 203 triggers the contact piece 301 to close the circuit, activating the warning light 302 and buzzer to issue an overcrowding alarm, providing a dual reminder to management for timely handling. The overcrowding threshold of the device can be flexibly set by adjusting the position of the contact piece 301 to adapt to the capacity requirements of different workshops, ensuring safe workshop management.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
