Description

An alert system to prevent personnel from going to the wrong unit Technical Field

[0001] This invention relates to the field of safety equipment and indicator technology, and in particular to a warning system to prevent personnel from going to the wrong unit. Background Technology

[0002] Thermal power plants typically have two sets of generating equipment per phase for the following reasons: (1) Reliable operation of the power plant: Power plants have regional power supply tasks and require that units be in operation at all times to generate electricity to users. Even power plants directly connected to high voltage need to provide reactive power support to the regional power grid. Considering that units may be under maintenance or experience failures, the most economical and best option to maintain the operation of units connected to the grid at all times is to use two units, which can meet the requirements of power supply reliability as much as possible without significantly increasing costs. In terms of reliability, two units provide much higher power supply reliability than one unit of the same capacity. (2) Flexible operation of power plants is generally necessary to adapt to changes in the load of grid users. Generating units cannot always operate at full load, especially in different seasons and at different times, where the average load varies greatly. If the unit load is too low, especially when it deviates significantly from the design conditions, the energy consumption for power generation will be very high. Thermal power units also need to inject oil for stable combustion at low loads, which is much more expensive than burning coal alone. If power supply cannot be guaranteed and the units cannot be shut down, having two units operating would be more flexible. In this case, one unit can be shut down and the load transferred to the unit that continues to operate, so that the operating unit can maintain a higher load and reduce coal consumption. (3) Power plant management requires a very detailed division of labor within the power plant. The operation, maintenance, and management personnel have different responsibilities. With two units, one can be under maintenance while the other is in operation, maintaining the normal operation of the power plant. Many auxiliary equipment and systems in a power plant are common. If there is only one unit, these equipment will be idle when the unit is under maintenance or malfunctions, resulting in low equipment utilization. If there are two units, these equipment and systems can operate all year round, which is more economical. In addition, two identical units can share spare parts, drawings, and personnel training, which can reduce management costs. This is why two units are usually built at a time when expanding.

[0003] Current situation: The two generating units share some equipment. When maintenance is required on parts of the unit or the entire unit, workers may mistakenly enter the wrong interval due to tight deadlines, affecting the safe operation of the unit and even neighboring units. Typically, when the entire unit is under maintenance and the neighboring unit is operating normally, hired temporary maintenance teams are unfamiliar with the plant's equipment locations and may enter the operating unit for maintenance due to time constraints, affecting its safe and stable operation. The plant is also facing staff shortages, often failing to maintain the required number of personnel per unit. This frequently results in the same person having tasks on both units, leading to the possibility of entering the wrong unit interval for operation and maintenance while isolating electrical and mechanical equipment. This poses a significant safety hazard to the unit's safe operation and, in severe cases, may affect the safe operation of the operating unit or even cause unplanned shutdowns, seriously impacting the safe operation of the power grid.

Detailed Implementation

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0035] Example 1

[0036] Referring to Figure 1, which illustrates the first embodiment of the present invention, a warning system is provided to prevent personnel from entering the wrong unit. The system includes an electronic fence component 100, installed between various unit areas, capable of detecting personnel crossing and automatically triggering audio-visual prompts; a ground guidance component 200, which lays a magnetic induction strip 201 and color-coded guidance markers 202 to distinguish between unit areas and guide personnel to the correct unit area; and a smart wearable component 300, integrating a magnetic sensitive element 302b and a feedback system, responding to changes in the ground magnetic field by providing audio-visual or vibration warnings.

[0037] Electronic fence component 100: The electronic fence installed between each unit uses laser or microwave beam technology to automatically monitor personnel crossing behavior. Once someone accidentally enters a non-target area, an audible and visual alert is immediately triggered to ensure that personnel receive an immediate warning and avoid misoperation.

[0038] Ground guidance component 200: Utilizes magnetic induction strips 201 laid on the ground. Each strip emits a magnetic field frequency corresponding to a specific unit, distinguished by different color-coded directional markers 202. This not only intuitively guides personnel to the correct unit but also interacts with the smart wearable component 300, forming a double layer of protection.

[0039] Smart wearable component 300: Wearable devices integrating magnetic sensing element 302b, such as safety helmets and armbands, which embed Hall effect sensors with magnetic sensing element 302b, are sensitive to changes in the ground magnetic induction zone 201. When a person deviates from the correct area, the sensor detects the non-corresponding magnetic field change, and the wearable device immediately activates audio-visual or vibration feedback, providing dual prompts and intuitively correcting incorrect behavior.

[0040] The warning device for preventing personnel from going to the wrong unit in this invention, by comprehensively utilizing the synergistic effect of the electronic fence component 100, the ground guide component 200 and the smart wearable component 300, not only achieves precise guidance and monitoring of personnel movement paths, but also shows significant improvements in safety, efficiency, cost-effectiveness and environmental adaptability, forming a comprehensive and multi-layered protection network to ensure the safety of operators and equipment.

[0041] The specific effects are reflected in:

[0042] Enhancing the immediacy and accuracy of safety warnings: The automatic detection and real-time audio-visual prompts of the electronic fence component 100, combined with the color-coded visual guidance of the ground magnetic induction strip 201, and the personalized vibration and LED feedback of the smart wearable component 300, form a triple warning system of visual, auditory, and tactile senses. This greatly shortens the reaction time of personnel to incorrect movement, effectively avoids accidentally entering dangerous areas, and improves personal safety.

[0043] Improving operational efficiency and autonomous navigation capabilities: The color-coded ground guidance components 200 interact with smart wearable devices, enabling workers to quickly locate themselves without external instructions and automatically adapt to the correct route, reducing time wasted on finding paths, improving work efficiency, and reducing reliance on external guidance.

[0044] Reduced maintenance costs and improved economic efficiency: The physical mechanism and mechanical linkage adopted by this system do not rely on a complex electronic control system, which reduces maintenance costs and failure rate. In the long run, the savings in operating costs are obvious and in line with the principle of economic efficiency.

[0045] Wide environmental adaptability: Whether indoors, outdoors, in strong light, at night, or in severe weather conditions, the color markings of the ground magnetic induction strip 201 and the vibration prompts of the smart wearable component 300 can work effectively without being limited by external conditions, ensuring all-weather and all-encompassing applicability.

[0046] In summary, this invention constructs an efficient, adaptive, low-cost, and safe personnel guidance system by integrating multiple prompting mechanisms of electronic fence component 100, ground guidance component 200, and smart wearable component 300. It significantly improves operational safety and management efficiency in complex multi-unit environments and is an innovative solution to existing technical problems.

[0047] Example 2

[0048] Referring to Figures 1-2, this is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the electronic fence component 100 includes multiple horizontally arranged laser beam detectors 101 for detecting personnel crossing behavior; a processor module 102, connected to the laser beam detectors 101, is used to analyze the obstruction sequence, determine the walking direction based on the order of personnel crossing, and make decisions accordingly; an audible and visual alarm module 103 responds to the judgment result of the processor module 102 and issues an audible and visual alarm prompt consistent with the judgment, to correctly guide personnel. The laser beam detectors 101 include at least two sets, each set consisting of a transmitter and a receiver. When a person obstructs any set of laser beams, the processor module 102 is activated to make a judgment; the processor module 102 has preset judgment logic and automatically switches the prompt message according to the unit's operating status.

[0049] Laser beam targeting assembly 101 deployment: First, at least two sets of laser beam targeting assemblies 101 are horizontally deployed at intervals between each unit. Each set includes a transmitter and a receiver, forming a precise beam channel. This setup ensures the invisibility of the physical barrier and real-time monitoring capabilities, sensitively detecting personnel crossing behavior.

[0050] Processor module 102 integrates the laser beam receiver 101, which is directly connected to the processor module 102 and is responsible for signal analysis and processing. A logic algorithm is used to determine the direction of movement based on the order in which a person blocks the laser beam (e.g., blocking one beam first, then two beams), thus determining whether they have mistakenly entered the wrong area. In this step, the optimized logic algorithm ensures the immediacy and accuracy of the judgment.

[0051] The specific algorithm logic is as follows:

[0052] (1) Input processing algorithm: The algorithm starts working when a person passes through the laser beam assembly 101. Each laser assembly consists of a transmitter and a receiver. The signal is triggered when the beam is blocked.

[0053] [Obstruction Event] = {Yes, No Line 1 is obstructed} or {Yes, Line 2 is obstructed}

[0054] (2) Logical judgment algorithm: After receiving the obstruction event, the processor module 102 judges the direction of travel according to the preset logic. If line 1 is obstructed before line 2, it indicates that the machine is entering unit 1; otherwise, if line 2 is obstructed before line 1, the machine is entering unit 2.

[0055] [Determine Direction] = \begin{cases}{Unit 1, &\text{if}\Obstruction Event = {Yes, Line 1 is obstructed, Line 2 is blocked}}\Unit 2, &\text{if}\Obstruction Event = {Yes, Line 2 is blocked, Line 1 is blocked}}end{cases}.

[0056] (3) Output algorithm: The audible and visual alarm module 103 outputs the result based on the judgment. If the direction is inconsistent with the actual direction (such as attempting to enter while the unit is in operation), an audible and visual alarm will be triggered; if the direction is correct, no alarm will be triggered, only guidance will be provided.

[0057] [Output] = begin{cases}{audio-visual alarm,\text{if}judgment =\text{direction}\neqdesired direction}\guidance,\text{if}judgment =\text{direction} =desired direction}end{cases}.

[0058] The audible and visual alarm module 103 responds immediately after the processor module 102 outputs the judgment result, providing audible and visual prompts based on the judgment result. If someone mistakenly enters the wrong area, an audible and visual alarm will be triggered, clearly indicating the correct direction, such as "You have entered the operating area of ​​Unit 1, please do not enter," ensuring that personnel can quickly correct their behavior.

[0059] Automated logic judgment: The processor module 102 automatically switches prompts based on the unit's status (operation or maintenance), such as "Maintenance" or "Operation," to adapt to actual operating conditions and improve the relevance of the prompts. This automation reduces human intervention and improves efficiency and flexibility.

[0060] Example: In a thermal power plant, Unit 1 is in operation, while Unit 2 is undergoing maintenance. Workers need to proceed to Unit 2. An electronic fence has been deployed between Units 1 and 2. When worker A crosses the fence, he first blocks line 1. The processor receives the signal and determines the direction is towards Unit 1. However, worker A does not enter Unit 1, and the audible and visual alarm module 103 immediately triggers, displaying the message "You have entered the operating area of ​​Unit 1, please do not enter," prompting worker A to correct his direction. Worker A then blocks line 2. This time, the processor correctly determines the direction, and the audible and visual alarm module stops triggering, only indicating "You have entered the maintenance area of ​​Unit 2," ensuring worker A proceeds correctly.

[0061] This solution, through the design of physical principles and actual operating procedures, combined with existing laser beams, processor technology, and audible and visual alarms, forms a practical warning system that ensures the feasibility and effectiveness of the technology, meets the requirements, and improves safety and efficiency.

[0062] The remaining structure is the same as that in Example 1.

[0063] Example 3

[0064] Referring to Figures 1 and 3-4, this is the third embodiment of the present invention. This embodiment differs from the second embodiment in that the ground guiding component 200 includes a magnetic induction strip 201 laid on the ground in a carpet-like manner. Each magnetic induction strip 201 emits a unique frequency magnetic field corresponding to that unit. Color-coded indicator 202 with arrows is provided on the upper surface of the magnetic induction strip 201, with each unit having its own color for differentiation.

[0065] Ground-laying magnetic induction strips 201: First, carpet-like magnetic induction strips 201 are laid between the units. Each magnetic induction strip 201 emits a unique magnetic field frequency corresponding to its unit, thus distinguishing them. For example, the magnetic strip emission frequency of unit 1 is F1, and that of unit 2 is F2.

[0066] Color guidance mark 202: Arrow color marks are set on the magnetic induction strip 201, with each unit corresponding to a different color, such as blue for unit 1 and red for unit 2, for easy identification.

[0067] The smart wearable component 300 includes a wearable device body 301 used daily by the user and a smart prompting module 302 added later to the wearable device body 301. The smart prompting module 302 includes a housing 302a, and a magnetic sensing element 302b, a small LED light strip 302c, a lightweight vibrating element 302d, and a circuit board processor 302e installed inside the housing 302a. The magnetic sensing element 302b is preferably a Hall effect sensor. The magnetic sensing element 302b is used to sense changes in the magnetic field emitted by the magnetic induction strip 201; the circuit board processor 302e receives and processes signals from the magnetic sensing element 302b, analyzes the frequency characteristics of the magnetic field to achieve rapid signal identification and processing, and issues a corresponding response mechanism; the small LED light strip 302c illuminates a light corresponding to the correct unit color, and the lightweight vibrating element 302d vibrates to alert the user that their current position is incorrect.

[0068] Smart wearable devices: Daily wearable equipment such as safety helmets, vests, belts, and name tags are equipped with a smart prompt module 302. The smart prompt module 302 includes a housing 302a, a magnetic sensitive element 302b, a small LED light strip 302c, a lightweight vibration element 302d, and a circuit board processor 302e. The magnetic sensitive element 302b is a Hall effect sensor, which accurately senses changes in the magnetic field.

[0069] Operating Procedure: When personnel enter the area, the magnetic sensing element 302b detects changes in the magnetic field of the magnetic induction strip 201, such as F1 or F2. The circuit board processor 302e receives and processes the signal, analyzes the magnetic field frequency F, and quickly identifies whether it is F1 or F2, i.e., machine number one or machine number two. If the wrong machine is entered, the small LED strip 302c corresponds to the wrong machine, such as blue light for F1 and red light for F2, and vibrates to indicate that the personnel have entered the wrong machine. If the correct machine is entered, there is no alarm, only the LED lights up, such as blue for F1, and no vibration, indicating that the machine is number one.

[0070] This technical solution achieves precise navigation for personnel without relying on intelligent control through physical mechanisms. Magnetic sensing, along with color, visual, LED, and vibration cues, ensures correct identification and prevents personnel from going to the wrong machine. The solution is practical, improves safety, and meets actual needs.

[0071] The remaining structure is the same as that in Example 2.

[0072] Example 4

[0073] Referring to Figures 3-5, this is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is: modification of the smart wearable device: among the daily wearable devices of personnel, such as safety helmets, vests, belts, work badges, etc., safety helmets are selected as the preferred wearable device body 301. The reason is that safety helmets are standard equipment for workers, integrating warning functions does not add extra burden, and they are directly associated with the head, with obvious visual and tactile warning effects.

[0074] A smart prompting module 302 is added, comprising a housing 302a, a magnetic sensitive element 302b, a small LED light strip 302c, a lightweight vibrating element 302d, and a circuit board processor 302e. A groove is provided on the outer wall of the housing 302a, and a suction cup adsorbed onto the outer wall of the wearable device body 301 is located within the groove. A suction tube extends through the housing 302a, with one end connected to the suction cup. A piston rod is located inside the suction tube. A magnetic ring is located on the inner wall of the suction cup. A magnetic block is located inside the wearable device body 301, and this magnetic block is magnetically attracted to the magnetic ring. The suction cup is made of a magnetic shielding material to shield the magnetic field between the magnetic block and the magnetic ring, preventing interference with the operation of the magnetic sensing element 302b's magnetic sensing strip 201. The lightweight vibrating element 302d includes a micro motor and a striking cam that sets the output shaft of the micro motor. The striking cam strikes the wall of the housing 302a and a friction wheel at the front end of the output shaft of the micro motor. The friction wheel rubs against the piston rod.

[0075] In this embodiment, firstly, one side of the shell 302a is designed as an arc-shaped structure that perfectly fits the shape of the safety helmet, and a suction cup is embedded in this side and closely adheres to the outer wall of the safety helmet, achieving initial physical contact. Next, a magnet is fixed inside the safety helmet, precisely aligned with the magnetic ring inside the suction cup. Magnetic attraction further strengthens the initial adhesion between the shell 302a and the safety helmet. At this stage, the intervention of magnetic attraction ensures that the shell 302a is firmly attached to the safety helmet, laying the foundation for subsequent reinforcement steps.

[0076] Subsequently, the micromotor inside the lightweight vibrating component 302d within the housing 302a is activated. This micromotor, through the friction of its rotating friction wheel inside the piston rod, cleverly causes the piston rod to slowly retract from the suction tube. This action creates a negative pressure effect at the connection between the suction cup and the suction tube, greatly enhancing the suction cup's adhesion to the outer wall of the helmet. This completes the secondary reinforcement installation of the housing 302a, ensuring that the housing 302a remains firmly in place even under conditions of severe movement or vibration.

[0077] In addition, another important function of the lightweight vibrating element 302d is to provide immediate physical feedback. When an alert is needed, the micro motor not only drives the impact cam to strike the wall of the housing 302a, producing a clear and audible warning sound, but each vibration also triggers the friction wheel again, causing the piston rod to move outward, further maintaining and optimizing the negative pressure adsorption effect. This ensures that while the warning sound and physical vibration provide a prompt, the housing 302a is also more securely fixed.

[0078] Through the above design, the intelligent helmet warning module 302 can be installed quickly and securely, and can provide obvious and effective vibration and sound warnings when necessary, which greatly enhances the safety and alertness of workers in complex environments and ensures the reliability and practicality of the system.

[0079] The remaining structure is the same as that in Example 3.
