Abstract
Description
Technical Field
[0001] The present application relates to the technical field of warning devices for specific areas such as the production of high-risk products, and in particular to an alarm device for tracking workers in a factory area. Background Art
[0002] Workshops involved in the production of high-risk products typically feature signs or devices restricting access to hazardous areas. In areas where hazardous equipment is installed, toxic gases, toxic raw materials, toxic waste, or high temperatures or pressures are present, personnel entering these hazardous areas for temporary work must maintain high vigilance to avoid casualties or property loss due to changes in hazardous factors in the production environment. However, these areas are not permanently hazardous. Some areas do not experience changes in hazardous factors during normal operations. These changes only occur during tasks such as commissioning equipment, heating and cooling, pressurization and depressurization, adding toxic raw materials, and unloading toxic waste. These operations are typically performed safely by dedicated personnel. In specific production scenarios, such as fertilizer and chemical plants, these production processes (including equipment and instruments) cannot be isolated, making the management and control of hazardous areas complex. This requires not only the control of space and personnel, but also the control of other adjacent production processes.
[0003] To prevent accidents, existing safety measures typically involve installing fixed alarm devices, such as audible and visual alarms, in hazardous areas. However, the impact of these areas on safety is dynamic, and workers entering these areas are often on the move. These measures are not effective in ensuring worker safety. Furthermore, the hours required for control in each hazardous area vary, making it easy for nearby workers to mistakenly enter. Expanding the control area would lead to reduced production capacity and other adverse effects. Utility Model Content

[0029] To facilitate understanding of the alarm device for tracking personnel in a specific area provided by the embodiments of the present application, its application scenario is first described. The alarm device for tracking personnel in a specific area provided by the embodiments of the present application is used in factory monitoring. Dangerous areas in the factory are often only provided with simple warning light indicators, which can easily cause people to mistakenly enter. To this end, the embodiments of the present application provide an alarm device for tracking personnel in a specific area to improve the safety of dangerous areas. The following is a detailed description of the device in conjunction with specific embodiments and accompanying drawings.
[0030] refer to Figure 1 As shown, Figure 1 The figure shows a schematic diagram of the structure of an alarm device for tracking people in a specific area provided by an embodiment of the present application. The alarm device for tracking people in a specific area provided by an embodiment of the present application includes multiple identification members 400. The identification members 400 can be worn by people working in dangerous areas. The identification members 400 are used to emit identification signals to provide information to identify people working in dangerous areas. People who are not wearing identification members 400 are considered to have illegally entered the dangerous area.
[0031] In addition, the alarm device for tracking people in a specific area also includes a support frame 100 and a marking rod 200, wherein the support frame 100 serves as the supporting structure of the entire device and is used to support the marking rod 200. The marking rod 200 is rotatably connected to the support frame 100 and can be locked in different positions. The rotation direction of the marking rod 200 can be referred to Figure 1The direction of the bidirectional arc example shown in FIG. For example, the marking rod 200 can be rotated relative to the support frame 100 and can be locked in the first setting position and the second setting position. Figure 1 1 shows a state when the marking rod 200 is in the first setting position, at which time the length direction of the marking rod 200 is perpendicular to the support frame 100. When the marking rod 200 is in the second setting position, the marking rod 200 is lifted.
[0032] Dangerous areas in a factory are generally protected by fences with openings for personnel to enter. The support frame 100 of the alarm device for tracking personnel in a specific area provided in the embodiment of the present application is set at the entrance of the dangerous area in the factory.
[0033] The alarm device for tracking people in a specific area provided in an embodiment of the present application also includes multiple electronic components to monitor people. Specifically, the alarm device for tracking people in a specific area also includes a power supply 10, a control switch 20, a signal receiving device 80, an infrared detector 70, an alarm device 60, and a first indicator light 30 and a second indicator light 90.
[0034] For reference Figure 1 and Figure 2 , Figure 2 The following is a logic block diagram of the electrical connection of the electronic devices provided in the embodiment of the present application. In a specific setting, the power supply 10 is fixed on the support frame 100, and the signal receiving device 80, the infrared detector 70, the alarm device 60, the first indicator light 30, the control panel 50, the second indicator light 90, etc. are arranged on the marking pole 200. In a specific connection, the control switch 20 is used to control the power supply 10 to supply power to the control panel 50, the infrared detector 70, the alarm device 60, the first indicator light 30, the second indicator light 90 and the signal receiving device 80, etc. The control switch 20 is a selection switch, and can select different electronic devices to be turned on according to the position of the marking pole 200. It should be understood that in Figure 1 The positions of various electronic components are exemplified in FIG. 1 , and the electronic components hidden in the marking rod 200 and the support frame 100 are also represented by solid lines, such as the power supply 10 and the control board 50 .
[0035] Specifically, when the marker rod 200 is locked in the first set position, the power supply 10 supplies power to the signal receiving device 80, the infrared detector 70, the control board 50, the second indicator light 90 and the alarm device 60 through the control switch 20. In a specific embodiment, the power supply 10 is in conductive communication with the control board 50 through the control switch 20, and the control board 50 is in conductive communication with the signal receiving device 80, the infrared detector 70, the second indicator light 90 and the alarm device 60, respectively. In use, the signal receiving device 80 is used to receive the identification signal. When a worker in the danger zone enters, the signal receiving device 80 can receive the identification signal sent by the identification member 400 worn by the worker, thereby identifying the worker as a worker in the danger zone. The infrared detector 70 is used to detect the entry of personnel, that is, as long as personnel enter the danger zone, the infrared detector 70 can detect it, regardless of whether the personnel wear the identification member 400. The alarm device 60 is used to issue an alarm.
[0036] When the control board 50 is in conductive communication with the signal receiving device 80, the infrared detector 70 and the alarm device 60, it can receive signals from the signal receiving device 80 and the infrared detector 70. When the infrared detector 70 detects the entry of personnel and does not receive the identification signal, the control board 50 controls the alarm device 60 to issue an alarm. For example, when personnel enter, the infrared detector 70 detects the entry of personnel, but the signal receiving device 80 does not receive the identification signal, it can be determined that the personnel are not workers in the danger zone, and the control board 50 controls the alarm device 60 to issue an alarm, on the one hand to remind the personnel not to enter the danger zone by mistake, and on the other hand to remind the workers in the danger zone. When the infrared detector 70 detects the entry of personnel and the signal receiving device 80 receives the identification signal, it is considered that the worker is a worker who can enter the danger zone.
[0037] In addition, the control board 50 is also used to control the second indicator light 90 to display when the marker rod 200 is rotated to the second set position, thereby reminding personnel that this place is prohibited from passing through, so as to play a warning effect.
[0038] It should be understood that the control board 50 receives signals and makes logical judgments based on the above-mentioned signals, which is a conventional control logic. The control logic is not improved in the embodiments of the present application, and only the conventional control logic in the prior art is used for judgment.
[0039] When the marker pole 200 is locked in the second set position, the power supply 10 supplies power to the first indicator light 30 via the control switch 20 and disconnects the electrical connections with the signal receiving device 80, the infrared detector 70, the control panel 50, the second indicator light 90, and the alarm device 60. When the marker pole 200 is in the second set position, the marker pole 200 is raised, which can be understood as a state where the danger zone can be entered. When the marker pole 200 is in the second set position, the power supply 10 supplies power to the first indicator light 30 via the control switch 20, which is used to indicate passage. In this state, the dangerous working area is considered to be in a dangerous state, and personnel can enter normally. In addition, in this state, the control switch 20 disconnects the power supply 10 from the signal receiving device 80, the infrared detector 70, the control panel 50, the second indicator light 90, and the alarm device 60, and the alarm device for tracking personnel in the specific area no longer monitors personnel.
[0040] In specific applications, the specific area personnel tracking alarm device provided in the embodiments of the present application can be applied to areas where periodic dangers occur. The above-mentioned specific areas refer to areas where periodic dangers exist. For example, in areas where dangerous equipment is installed, or where toxic gases, toxic raw materials, toxic hazardous waste products are present, or where high temperature or high pressure environments are present, personnel entering such dangerous areas for temporary work must remain highly vigilant to avoid casualties or property losses caused by changes in hazardous factors in the production environment. However, such areas are not permanently hazardous. In some areas, the hazardous factors do not change during normal working conditions. Changes in hazardous factors only occur during work steps such as debugging equipment, heating and cooling, pressurization and decompression, adding toxic raw materials, and unloading toxic hazardous waste products. Typically, these operations are performed safely by specialized operators. For example, in fertilizer chemical plants, such production links (including equipment and instruments) cannot be isolated and set up separately. When a hazardous state occurs in these areas, the specific area personnel tracking alarm device can be installed at the entrance and these areas can be isolated by fencing. The marker rod 200 of the alarm system for tracking personnel in a specific area is rotated to the second set position to warn other personnel to avoid erroneous entry. Specific operators who are allowed to enter the area are required to wear identification pieces 400 to prevent the alarm from being triggered when entering the area. If other personnel unaware of the situation enter the area, the alarm device 60 of the alarm system for tracking personnel in a specific area will sound an alarm to alert the erroneous person and the operators in the area.
[0041] As described above, in the embodiments of the present application, by using marker poles at different locations, a specific work area can be specifically indicated as either a safe, accessible state or a dangerous, inaccessible state. Identification signals are then used to identify whether a person entering a specific area meets the warning status requirements, and corresponding warning signals are issued based on the identification results. The warning scheme can be dynamically adjusted based on actual needs, effectively protecting the lives and property of workers and minimizing adverse effects on production activities.
[0042] Continue to refer Figure 1 As shown, when the support frame 100 is connected to the marking pole 200, the support frame 100 and the marking pole 200 are rotatably connected through the rotating shaft 300, wherein the length direction of the rotating shaft 300 is perpendicular to the axis of the support frame 100, so that the marking pole 200 can block a certain area of the entrance to the danger zone when it is lifted and lowered.
[0043] The control switch 20 provided in the embodiment of the present application operates in a manner similar to a single-pole double-throw switch. The control switch 20 includes a fixed end 22 and two movable ends 21. The fixed end 22 is fixed to the support frame 100, while the two movable ends 21 are respectively fixed to the marker pole 200 and are rotatable about the rotation axis 300. One movable end 21 is electrically connected to the first indicator light 30, while the other movable end 21 is electrically connected to the control board 50. The control board 50 is electrically connected to the infrared detector 70, the alarm device 60, the second indicator light 90, and the signal receiving device 80. During use, when the marker pole 200 is rotated to the first set position, the movable end 21 electrically connected to the control board 50 is electrically connected to the fixed end 22, and the power supply 10 supplies power to the infrared detector 70, the signal receiving device 80, the second indicator light 90, and the alarm device 60 through the control board 50. When the marking rod 200 rotates to the second set position, the movable end 21 connected to the first indicator light 30 is electrically connected to the fixed end 22, and the electronic components such as the control board 50 are disconnected from the power supply 10.
[0044] When the marking rod 200 is rotatably connected to the support frame 100, one end of the marking rod 200 that is rotatably connected to the support frame 100 is provided with multiple slots. The slots are arranged around the rotating shaft 300, and the support frame 100 is provided with elastic protrusions that engage with the slots. When the marking rod 200 rotates, the elastic protrusions can be inserted into different slots. When the marking rod 200 rotates to the first set position or the second set position, the elastic protrusions engage with the corresponding slots, thereby locking the marking rod 200. When multiple slots are used, the marking rod 200 can be locked in multiple positions to provide different states. For example, when the marking rod 200 is in a position other than the first set position or the second set position, the control switch 20 is in the off state, at which time the control board 50, power supply 10, or other electronic components can be repaired or replaced.
[0045] Furthermore, a U-shaped notch is provided at one end of the support frame 100 that rotatably engages the marker rod 200. The end of the marker rod 200 that rotatably engages the support frame 100 is located within the notch. Elastic protrusions are provided on the opposing sidewalls of the notch, and a retaining groove is provided on the opposing sidewalls of the end of the marker rod 200 that rotatably engages the support frame 100. In other words, the opposing sidewalls of the notch of the support frame 100 engage with the marker rod 200, thereby locking the opposing sides of the marker rod 200 and improving the locking effect of the marker rod 200 after it stops rotating.
[0046] In an optional embodiment, the alarm device 60 provided in the present application includes a light alarm device and / or a voice alarm device. For example, the alarm device 60 may include only a light alarm device, only a voice alarm device, or both. These different alarm devices 60 can provide different alarm signals, such as sound and light, and different alarm devices 60 can be selected as needed during specific configuration.
[0047] In an optional solution, the alarm device for tracking personnel in a specific area also includes a signal transmitting device 40 fixed to the marking pole 200, and the corresponding control panel 50 is also used to control the signal transmitting device 40 to issue an alarm to the central control console of the factory when the infrared detector 70 detects that a person has entered and no identification signal has been received. That is, when the control panel 50 determines that a person from a non-hazardous area has entered, it issues an alarm to the central control console of the factory so that the monitoring personnel of the factory can quickly learn of the situation. Of course, the monitoring personnel can also send a voice signal to the control panel 50 through the central control console, and the control panel 50 will issue a voice reminder through the voice alarm device. The above-mentioned signal transmission and processing are all common signal transmission and processing methods in the prior art, and will not be described in detail in the embodiments of this application.
[0048] Continue to refer Figure 1 As shown, the support frame 100 provided in the embodiment of the present application includes a base 120 and a column 110, the power supply 10 is arranged on the column 110, and the column 110 is rotatably connected to the marking rod 200. Figure 1 As shown in , the base 120 has a larger supporting area. When the base 120 cooperates with the column 110, the supporting effect on the marking pole 200 can be improved.
[0049] As an optional solution, the base 120 is provided with lockable universal wheels 130, so that the base 120 can be easily moved and can be easily moved when the positions of the support frame 100 and the marking rod 200 need to be adjusted.
[0050] The one or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the scope of protection of this disclosure.
[0051] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application.
