[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0023] In order to solve the problem of inadequate safety protection of mechanical equipment during operation in the prior art, the present application provides a warning device for mechanical equipment.

[0024] like Figure 1 As shown, the warning device for mechanical equipment includes a plurality of infrared sensors 10, an alarm device, a control module 40 and a communication module. At least one infrared sensor 10 is arranged on the rotating shaft 20 of the mechanical equipment, and at least another infrared sensor 10 is arranged on the movable arm 30 of the mechanical equipment. Each infrared sensor 10 emits infrared rays to form a warning area 50 on the working surface of the mechanical equipment. The control module 40 is electrically connected to each infrared sensor 10 and the alarm device. The control module 40 transmits signals with the main control module of the mechanical equipment through the communication module to send a shutdown command to the main control module. When the infrared rays emitted by at least one infrared sensor 10 encounter an obstacle, the alarm device is controlled by the control module 40 to send an alarm signal and send a shutdown command to the main control module.

[0025] By applying the technical solution of this embodiment, when the mechanical equipment is in working condition, if the operator or maintenance personnel mistakenly enters the warning area 50, the infrared rays emitted by at least one infrared sensor 10 encounter an obstacle (operator or maintenance personnel), and the infrared sensor 10 sends a signal to the control module 40. After receiving the above signal, the control module 40 controls the alarm device to send an alarm signal and sends a shutdown command to the main control module, so as to remind the operator or maintenance personnel through the alarm signal, and control the mechanical equipment to shut down through the shutdown command, thereby avoiding mechanical injury accidents, solving the problem of inadequate safety protection of mechanical equipment during operation in the prior art, and improving the safety of mechanical operations.

[0026] In this embodiment, after the infrared sensor 10 emits infrared rays, the movement trajectory of the mechanical equipment is visualized, which serves as a warning to people around the mechanical equipment.

[0027] In this embodiment, the alarm device is an audible and visual alarm. Thus, the use of the audible and visual alarm can not only alert the operator through sound, but also draw attention in a noisy environment through flashing lights, ensuring that the operator can promptly detect the warning signal even in a noisy environment, thereby improving the warning reliability of the warning device.

[0028] Optionally, the warning device further includes a plurality of image acquisition devices and a plurality of fill lights. The plurality of image acquisition devices are electrically connected to the control module 40, and the plurality of image acquisition devices are arranged at intervals on the mechanical equipment. The plurality of fill lights are arranged in a one-to-one correspondence with the plurality of image acquisition devices. In this way, the above-mentioned arrangement of the image acquisition devices and the fill lights enables the warning device to continue to work in an environment with insufficient light or in complete darkness, and to capture the situation around the mechanical equipment in real time. For example, in low-light environments such as construction sites, underground mines, or tunnel construction at night, the work area can be illuminated by the fill lights even in a completely dark environment, and the clear images captured by the image acquisition devices can be transmitted to the control module 40 in a timely manner, ensuring that there are no blind spots in safety monitoring at night or in low-light environments, thereby greatly improving the safety and reliability of mechanical equipment in complex environments.

[0029] Optionally, the warning device also includes a fluorescent panel. The fluorescent panel is located within the warning area 50. When infrared rays emitted by each infrared sensor 10 strike the panel, the panel emits visible light. This arrangement makes the warning area 50 more visible at night or in low-light environments, enhancing operator visual recognition. Especially during nighttime operations, the visible light emitted by the fluorescent panel serves as a bright warning sign, effectively reminding operators to avoid approaching mechanical equipment, reducing safety hazards caused by poor visibility and ensuring safe nighttime operations.

[0030] Optionally, multiple fluorescent panels can be spliced ​​onto the work surface. By splicing multiple fluorescent panels, a larger warning area 50 can be formed. Furthermore, the spliced ​​fluorescent panels can adapt to machinery of various sizes and shapes, providing comprehensive safety protection for large machinery and high-risk work areas. This ensures that operators can clearly see the warning signs regardless of the angle from which they approach the machinery, effectively avoiding potential dangers caused by limited viewing angles.

[0031] Optionally, the warning device also includes a battery. The battery powers at least one of the infrared sensor 10, the alarm device, the communication module, the control module 40, the image acquisition device, and the fill light. This built-in battery design enables the warning device to operate independently, unrestricted by an external power source. This is particularly important for protecting equipment safety in environments without stable power sources, such as mobile machinery, field operations, and temporary construction. For example, in oil production in remote areas, a battery-powered warning device can operate continuously, providing stable safety warnings and significantly enhancing the safety and reliability of mechanical equipment in field operations.

[0032] Optionally, the warning device further includes a plurality of first protective covers, which are provided in a one-to-one correspondence with the plurality of infrared sensors 10, and each first protective cover is provided outside the corresponding infrared sensor 10; and / or the warning device further includes a plurality of second protective covers, which are provided in a one-to-one correspondence with the plurality of image acquisition devices, and each second protective cover is provided outside the corresponding image acquisition device. In this way, the above-mentioned provision of the first protective cover and / or the second protective cover not only protects the infrared sensor and the image acquisition device from physical damage, but also prevents the influence of dust, water vapor and corrosive gases on the equipment. This ensures the normal operation of the infrared sensor 10 and / or the image acquisition device, extends its service life, and at the same time, ensures the detection accuracy and reliability of the infrared sensor 10 and / or the image acquisition device.

[0033] In this embodiment, the warning device further includes a plurality of first protective covers and a plurality of second protective covers. The plurality of first protective covers are provided in a one-to-one correspondence with the plurality of infrared sensors 10, and each first protective cover is provided outside its corresponding infrared sensor 10. The plurality of second protective covers are provided in a one-to-one correspondence with the plurality of image acquisition devices, and each second protective cover is provided outside its corresponding image acquisition device.

[0034] Optionally, the first protective cover is an arc-shaped structure.

[0035] Optionally, the second protective cover is an arc-shaped structure.

[0036] Optionally, the infrared sensor 10 can be installed at a height of 2 to 4 meters. This allows the infrared sensor 10 to cover most of the area surrounding the machinery, particularly areas where operators and obstacles are most likely to appear. Furthermore, this height ensures that infrared radiation reaches the ground while avoiding blind spots caused by installation too high, ensuring effective safety protection for machinery operating at any height.

[0037] In this embodiment, the installation height of the infrared sensor 10 is 3 meters.

[0038] It should be noted that the installation height of the infrared sensor 10 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the installation height of the infrared sensor 10 is 2.5m, or 2.8m, or 3.2m, or 3.5m, or 3.8m.

[0039] Optionally, the infrared sensor 10 is a pyroelectric infrared sensor. In this way, the pyroelectric infrared sensor not only has high sensitivity and stability, but also has good anti-interference ability. It can accurately detect the approach of people or obstacles in complex environments. It is suitable for the safety protection of mechanical equipment in various industrial environments. For example, it can maintain stable operation in high temperature, low temperature, and high humidity environments, providing a guarantee for the safe operation of equipment in extreme environments.

[0040] Optionally, the warning device also includes a signal processing module. The signal processing module is electrically connected to the communication module and the control module 40 to amplify and / or filter the shutdown command. In this way, the above-mentioned setting of the signal processing module improves the transmission stability and accuracy of the shutdown command, ensures that the mechanical equipment can stop running promptly and accurately after receiving the shutdown command, and avoids safety hazards caused by signal transmission delays or false alarms. At the same time, in complex electromagnetic environments such as near power facilities and areas with dense electronic equipment, the signal processing module can effectively filter electromagnetic interference, ensure the accuracy of the shutdown command, and provide solid technical support for the safety protection of equipment in electromagnetic interference environments.

[0041] Optionally, the infrared sensor 10 includes an ambient temperature compensation function. This ensures that the infrared sensor 10 maintains high detection accuracy in varying temperature environments, making it suitable for protecting machinery and equipment in environments with significant temperature fluctuations. For example, during seasonal outdoor operations or in industrial workshops subject to temperature fluctuations, the ambient temperature compensation function automatically adjusts the sensor's sensitivity to avoid false or missed alarms due to temperature fluctuations, providing an intelligent solution for protecting equipment in temperature-stable environments.

[0042] Optionally, upon detecting a person touching the infrared ray, the control module 40 can automatically record the time, location, and frequency of the touch event. This configuration not only helps operators and managers understand the safety conditions surrounding the machinery and equipment but also facilitates accident analysis and prevention. In densely populated environments such as factories and high-risk chemical plants, recording the time, location, and frequency of touch events can help analyze patterns of human activity, optimize machinery and equipment layout and operational processes, identify potential safety risks in advance, and implement corrective measures, thereby effectively reducing the accident rate and improving the safety and efficiency of industrial production.

[0043] Optionally, the alarm device can adjust the intensity of the alarm signal based on the machine's operating status. This ensures adequate attention in all circumstances. Especially when the machine is operating at high speeds or in high-risk operating conditions, the enhanced alarm signal can more effectively alert operators to safety and avoid potential safety hazards caused by insufficient alarm signal strength. This dynamic adjustment mechanism also reduces noise pollution when the machine is operating at low speeds or in non-operating states, improving the safety protection and environmental performance of the equipment under different operating conditions.

[0044] Optionally, after detecting that a person has touched the infrared rays, the control module 40 can automatically record the time, location, and number of touch events, and send a warning message to the main control module when the event record reaches a preset threshold. In this way, the above-mentioned warning information sending mechanism can prevent potential safety risks in advance when the event record reaches a preset threshold. In repetitive work environments, such as production lines and storage logistics centers, this mechanism can analyze the frequency and patterns of touch events, identify operating modes or equipment layouts that may pose safety hazards, and take measures in advance to provide warnings and interventions to avoid the accumulation of safety risks, thereby effectively reducing the possibility of accidents and improving work efficiency and personnel safety.

[0045] Optionally, the emission angle and distance of the infrared sensor 10 are adjustable to meet the protection requirements of different mechanical equipment. This adjustability of the emission angle and distance of the infrared sensor 10 allows the warning device to flexibly adapt to the protection requirements of various mechanical equipment. It is applicable not only to fixed equipment, such as production lines within factories and stackers in warehouses, but also to mobile equipment, such as excavators on construction sites and transport vehicles in logistics centers. Customized settings can be made based on the size of the equipment, operating range, and working environment, ensuring the effectiveness and practicality of the warning device on various mechanical equipment, providing a more comprehensive and flexible solution for industrial safety protection.

[0046] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0047] The warning device includes multiple infrared sensors, an alarm device, a control module, and a communication module. At least one infrared sensor is positioned on the rotating shaft of the mechanical device, and at least one other infrared sensor is positioned on the movable arm of the mechanical device. Each infrared sensor emits infrared radiation to form a warning zone on the working surface of the mechanical device. The control module is electrically connected to each infrared sensor and the alarm device. The control module transmits signals to the mechanical device's main control module via the communication module to send a shutdown command to the main control module. Thus, when the mechanical device is in operation, if an operator or maintenance personnel accidentally enters the warning zone, the infrared radiation emitted by at least one infrared sensor encounters an obstacle (the operator or maintenance personnel). The infrared sensor sends a signal to the control module. Upon receiving this signal, the control module controls the alarm device to emit an alarm signal and sends a shutdown command to the main control module. This alarm signal alerts the operator or maintenance personnel, and the shutdown command controls the mechanical device to shut down, thereby preventing mechanical injuries. This solves the problem of inadequate safety protection for mechanical equipment during operation in the prior art and improves the safety of mechanical operations.
