Description

Technical Field

[0001] This utility model relates to the field of chemical safety monitoring technology, specifically a vital signs monitoring system for personnel cleaning chemical storage tanks. Background Technology

[0002] In the chemical industry, large storage tanks are used to store various chemical raw materials. Over time, sediment accumulates at the bottom of the tanks, requiring workers to enter and clean them. However, the tanks contain large amounts of toxic gases, posing a serious threat to the lives of the workers. Although workers are currently wearing masks and receiving air from an external air compressor, the working environment remains dangerous.

[0003] Current safety monitoring methods primarily involve installing cameras on top of the tank, relying on external supervisors to monitor workers' conditions over extended periods. However, this method has significant drawbacks. Prolonged monitoring can easily lead to human negligence, failing to detect changes in workers' vital signs promptly and accurately. In emergencies, timely rescue is difficult, potentially causing serious accidents. Furthermore, existing equipment requires workers to wear two systems: one for vital sign monitoring and the other for voice communication, which is cumbersome and inconvenient to carry. Regarding voice communication, speaking requires button operation, preventing workers from speaking freely and significantly limiting communication efficiency. In emergency situations, delays in button operation may prevent the timely transmission of critical information. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides an embodiment: Please refer to Figures 1-3 A vital signs monitoring system for chemical storage tank cleaning workers includes terminal equipment, signal relay equipment, and a command unit. The terminal equipment is worn by the workers and integrates multiple key components, including a vital signs detection module, a voice communication module, an environmental monitoring module, an alarm module, and a microprocessor. The vital signs detection module, voice communication module, environmental monitoring module, and alarm module are all connected to the microprocessor. During use, the vital signs detection module collects the workers' vital signs in real time and uploads the collected signals to the microprocessor. The voice communication module automatically captures and transmits voice signals to the microprocessor, allowing workers to communicate with others in real time. The environmental monitoring module monitors the working environment and uploads the collected data to the microprocessor. The microprocessor integrates and analyzes the received data and, when abnormal vital signs or environmental data are detected, controls the alarm module to issue an alarm to alert the workers.

[0021] The aforementioned vital sign detection modules include, but are not limited to, a respiratory sensor, a heart rate sensor, a blood pressure sensor, a body temperature sensor, and an electrocardiogram (ECG) sensor. The respiratory sensor is installed inside the protective mask worn by the worker and uses a high-precision HKH-21L mask-type respiratory sensor to accurately monitor the worker's breathing rate, depth, and other signals, providing crucial data for assessing the worker's physical condition. The heart rate sensor is worn on the worker's chest and uses an HKX-08A heart rate sensor to accurately acquire heart rate data through electrode attachment, ensuring accurate heart rate monitoring. The blood pressure sensor, body temperature sensor, and ECG sensor are all installed on the worker's wrist. The blood pressure sensor is used to detect the worker's blood pressure, the body temperature sensor is used to detect the worker's body temperature, and the ECG sensor is used to detect the worker's heart signals.

[0022] The voice communication module is used to collect the voice signals of workers, but the situation is more challenging in the complex environment inside the storage tank. On the one hand, the storage tank itself generates mechanical noise, which continuously interferes with sound acquisition; on the other hand, workers also generate additional noise when operating the machinery. Traditional microphones in such an environment would pick up all this complex noise, severely affecting the recognizability of the target voice. To address this problem, the voice communication module in this application breaks through the traditional microphone's reliance on air conduction for sound and adopts a unique bone conduction technology. Its working principle is based on the characteristic that human bones can conduct sound. When a person speaks, the sound waves generated by the vibration of the vocal cords not only travel through the air but also cause vibrations in the facial bones. The bone conduction voice recognizer fits closely to the human face and can accurately capture the sound signals carried by these bone vibrations. Unlike air conduction, bone conduction directly transmits signals with minimal signal loss. The original signal strength is many times stronger than that of air conduction, avoiding the superposition of environmental noise. Subsequently, a special conversion device inside the bone conduction voice recognizer converts the permeation signal from bone conduction into a voltage signal, completing the sound acquisition process.

[0023] Furthermore, the bone conduction voice recognition device is placed close to the face, utilizing the face's shielding effect against ambient noise to isolate most environmental noise and focus solely on capturing the voice transmitted through the human skeleton. Combined with its characteristics of minimal signal loss, strong original signal, and avoidance of ambient noise superposition, it effectively improves call quality, significantly enhances the signal-to-noise ratio, and makes voice communication clearer and more accurate. Its voice capture performance in noisy environments such as inside storage tanks is far superior to that of traditional microphones.

[0024] The voice communication module includes a bone conduction voice recognition device and an earphone. The bone conduction voice recognition device is placed on the face and is based on 2.4G digital communication technology. It supports simultaneous conversations of up to seven people. When one person speaks, everyone else can hear. No button operation is required when speaking. As long as the operator speaks, the system can automatically capture and transmit the voice signal. By inserting the earphone into the terminal, real-time communication with other people can be achieved.

[0025] The environmental monitoring module includes, but is not limited to, gas detection sensors and proximity sensors. Gas detection sensors are used to detect the content of harmful gases in chemical storage tanks, while proximity sensors are used to detect high-voltage electric fields to prevent the risk of electric shock.

[0026] The alarm module can be an existing audible and visual alarm. The microprocessor can send alarm commands to the alarm module, and the alarm module will trigger an alarm based on the alarm commands, so that the operators can understand their own status and the environmental status in a timely manner.

[0027] The terminal device also includes a power module, which is connected to the vital signs detection module, voice communication module, environmental monitoring module, alarm module, and microprocessor. The power module supplies power to the other modules in the terminal device. The power module can be a lithium battery, which is small in size and has an integrated hook, making it highly integrated, convenient for operators to wear and use, and reducing the burden on the equipment.

[0028] As described above, the terminal equipment can monitor the vital signs of workers and the working environment in real time, providing strong protection for safe operation and keeping the physical condition of workers under constant monitoring so that any abnormalities can be detected in a timely manner.

[0029] The terminal devices interact with the command center via signal relay equipment. ZigBee wireless networking technology is used for data exchange between the terminal devices and the signal relay equipment, as well as between the signal relay equipment and the command center. Considering that chemical storage tanks are mostly made of metal, which strongly shields wireless signals, a high-performance router is installed at the opening on the top of the tank as a signal relay device. Signals emitted by the terminal devices are first transmitted to this router. The router utilizes its powerful signal amplification and forwarding capabilities to stably transmit the signal to the command center, ensuring the stability and reliability of data transmission, preventing signal interruptions or loss during transmission, and guaranteeing the smooth transmission of vital signs data and voice communication signals.

[0030] ZigBee wireless networking technology features self-organizing and self-healing capabilities, integrating signals from multiple terminal devices worn by workers and transmitting them uniformly to the command center. Compared to traditional wired communication, it significantly reduces the workload of workers, improves operational flexibility, and allows workers to move freely inside the tank without being restricted by cables, enabling them to perform cleaning operations more freely.

[0031] The command center connects to a computer, audio system, and microphone. Data exchange occurs between the command center and these components via a communication protocol. The computer has built-in monitoring software and is connected to an alarm system. Data uploaded from terminal devices is relayed through a router, aggregated at the command center, and then uploaded to the computer's monitoring software for visual display. Staff can set alarm thresholds on the monitoring software based on actual conditions, such as different working environments and the physical condition of workers. If a worker's vital signs exceed normal ranges, the system immediately triggers an alarm using both audible and visual cues, effectively preventing accidents caused by human negligence. Simultaneously, the command center can communicate in real-time with workers inside the tank via the audio system and microphone, providing timely guidance and rescue.

[0032] In summary, this vital sign monitoring system for chemical storage tank cleaning personnel enables real-time and accurate monitoring of workers' vital signs, promptly identifying and alerting to safety hazards, thus ensuring worker safety. Simultaneously, it optimizes voice communication functions, improving communication efficiency and reducing staff workload. It addresses the shortcomings of existing monitoring methods, achieving real-time and accurate monitoring, reducing human error, providing convenient communication and action, and safeguarding worker safety.

[0033] The following will further explain this application through the steps of its use.

[0034] Terminal device installation and wearing: Before the cleaning operation, ensure that each worker wears the terminal device correctly. Debug the bone conduction voice recognition device and 2.4G digital communication module, simulating different voice communication scenarios such as noisy and quiet environments to ensure clear, stable, noise-free, and delay-free voice communication. Simultaneously, check that the lithium battery has sufficient power and securely attach the terminal device to the worker using the integrated hook.

[0035] System Networking and Debugging: Securely install the router at the opening on the top of the tank and configure it precisely according to the site environment and equipment parameters to ensure stable wireless communication with terminal devices. Correctly connect the command unit to the computer, audio system, and microphone, ensuring a secure physical connection. Install the appropriate data display and alarm software, setting reasonable alarm thresholds, such as a normal respiratory rate of 10-20 breaths / minute and a normal heart rate of 60-120 beats / minute. Conduct a comprehensive system debugging, simulating operational scenarios to test the normality of communication between devices, the accuracy of data transmission, the sensitivity and reliability of alarm functions, and the smoothness of voice communication. For example, simulate abnormal vital signs of workers to check if the alarm function responds promptly; simulate simultaneous voice communication by multiple people to check if the voice is clear and without interruptions.

[0036] Operation Monitoring: During the operation, terminal equipment collects real-time vital sign data of workers and operational environment data. The collected data is integrated by a microprocessor and rapidly transmitted to a router via ZigBee wireless networking. From there, it is relayed to the command center and clearly displayed on the computer software. Simultaneously, workers maintain real-time communication with command personnel and other staff via bone conduction microphones and 2.4G digital communication technology. If the microprocessor detects any data anomalies during data integration, it triggers an alarm. Command personnel closely monitor data changes on the computer software. Upon detecting any abnormalities, such as excessively rapid or slow breathing or abnormally high heart rate, they immediately contact the workers via speaker and microphone to inquire about the situation and take appropriate rescue measures, such as instructing workers to suspend operations or evacuate the tank, ensuring the safety of the workers.
