Description

Technical Field

[0001] This application belongs to the technical field of marine oil emergency early warning, and relates to a safety helmet and a water-fall warning device. Background Technology

[0002] Offshore oil exploration platforms are marine engineering facilities used for near-shore and offshore oil exploration, primarily undertaking functions such as oil and gas extraction, processing, storage, and monitoring. Structurally, they can be divided into two main categories: fixed (pile-based, gravity-based) and floating (jack-up, tension leg) platforms. The materials are mostly steel or concrete, with some employing hybrid structures.

[0003] Offshore oil exploration platforms are the main facilities for offshore oil exploration. The decks where personnel live and work on these platforms are at least 20 meters above sea level. Figure 1 As shown. Therefore, if a person falls into the water from the platform and is not detected in time, there is a high probability that they will be lost.

[0004] Workers in this field have not found a good way to warn of people falling into water, and usually discover accidents through regular manual roll calls or reports from workers. Therefore, there is a significant delay in obtaining information about falls into water, which delays rescue time for those who have fallen into the water. Summary of the Invention

[0010] In one implementation of the first aspect, the wireless data transmission module includes a 485 communicator; the 485 communicator is connected to the altitude data acquisition card.

[0011] In one implementation of the first aspect, a switch is also included; the switch is disposed at the outer opening of the safety helmet and is connected in series in the power supply line of the battery.

[0012] Secondly, this application provides a water fall warning device, comprising: the aforementioned safety helmet, a distributed signal relay system, and a monitoring and alarm device; the distributed signal relay system is communicatively connected to the safety helmet and the monitoring and alarm device respectively.

[0035] Please see Figure 2 The diagram shows the structural connections of the safety helmet described in this embodiment. Figure 2 As shown, this embodiment provides a safety helmet 1, including: an altitude testing module 11, an altitude data acquisition card 12, a wireless data transmission module 13, and a battery 14.

[0036] The altitude testing module 11 detects the altitude data of the helmet wearer based on the altitude changes of the helmet wearer.

[0037] The altitude data acquisition card 12 is connected to the altitude test module 11 to collect the altitude data.

[0038] The wireless data transmission module 13 is connected to the altitude data acquisition card 12.

[0039] The battery 14 is connected to the altitude test module 11, the altitude data acquisition card 12, and the wireless data transmission module 13 respectively, and supplies power to the altitude test module 11, the altitude data acquisition card 12, and the wireless data transmission module 13.

[0040] Please see Figure 3 The diagram shows the structural principle of the safety helmet described in the embodiments of this application. Figure 3 As shown, the helmet also includes a charging port.

[0041] The charging port is located at the outer opening of the helmet. One end of the charging port is connected to an external charging device, and the other end is connected to the battery.

[0042] In practical applications, the charging voltage of the safety helmet for the charging port needs to be determined according to the specific model and battery type, usually from 3.7V to 4.2V, and some models support 4.2V DC power supply charging.

[0043] In practical applications, the battery includes a lithium battery, which is connected to the altitude testing module, the altitude data acquisition card, and the wireless data transmission module, respectively, and supplies power to these components.

The altitude testing module 11 transmits altitude data to the altitude data acquisition card 12, and the altitude data acquisition card 12 converts the altitude data into wireless signal data and transmits it to the wireless data transmission module 13.

[0045] like Figure 3 As shown, the safety helmet also includes an antenna interface; the antenna interface is located at the edge of the safety helmet and is connected to the wireless data transmission module 13.

[0048] In practical applications, the altitude data acquisition card includes a microcontroller unit (MCU). The MCU can be a chip integrating a central processing unit (CPU), memory, counters, and an ADC (Analog-to-Digital Converter). For example, the MCU can be an enhanced version of the ARM Cortex-M3 architecture microcontroller STM32F103RBT6. The STM32F103RBT6 operates at a frequency of up to 72MHz, enabling high-end computation and featuring abundant enhanced I / O (Input / Output) ports. Enhanced devices typically include 2-3 12-bit ADCs, 4 general-purpose 16-bit timers, and 2 PWM (Pulse Width Modulation) timers. The STM32F103RBT6 features 51 multi-functional bidirectional 5V compatible I / O ports. These can be used as general-purpose GPIO (GPIO) ports or alternate-function AFIO (AFIO) ports. Each GPIO pin can be configured in the program as follows: floating input, pull-up input, pull-down input, analog input, open-drain output, push-pull output, push-pull alternate-function, and open-drain alternate-function.

[0049] Please see Figure 4 The image shown is a structural schematic diagram of the water-fall warning device described in an embodiment of this application. Figure 4 As shown, this embodiment provides a water fall warning device, including: a safety helmet 1, a distributed signal relay system 2, and a monitoring and alarm device 3.

[0050] The safety helmet 1 includes: an altitude testing module 11, an altitude data acquisition card 12, a wireless data transmission module 13, and a battery 14. The altitude testing module 11 detects the altitude data of the helmet wearer based on changes in altitude.

[0051] The distributed signal relay system 2 is communicatively connected to the safety helmet 1 and the monitoring and alarm device 3, respectively.

[0052] In one embodiment, the water-fall warning device further includes an electrical signal converter.

[0053] The distributed signal relay system (distributed signal amplification) includes a first relay device facing east from the offshore oil exploration platform, a second relay device facing south from the offshore oil exploration platform, a third relay device facing west from the offshore oil exploration platform, and a fourth relay device facing north from the offshore oil exploration platform; the first relay device, the second relay device, the third relay device, and the fourth relay device are all communicatively connected to the electrical signal converter, and the electrical signal converter is communicatively connected to the monitoring and alarm device.

[0054] In one embodiment, the safety helmet includes individual safety helmets for different personnel on an offshore oil exploration platform.

[0055] Each of the safety helmets is communicatively connected to the first relay device, the second relay device, the third relay device, and the fourth relay device.

[0057] Please see Figure 5 The diagram shows the communication architecture of the water-fall warning device described in this application embodiment. Figure 5 As shown, the safety helmets include various helmets for different personnel on the offshore oil exploration platform. Safety helmets 1, 2, 3, and 4 are all communicatively connected to the first relay device (a distributed signal amplification relay device facing east of the platform), the second relay device (a distributed signal amplification relay device facing south of the platform), the third relay device (a distributed signal amplification relay device facing west of the platform), and the fourth relay device (a distributed signal amplification relay device facing north of the platform). The first, second, third, and fourth relay devices are all communicatively connected to an RS485 electrical signal converter, which converts the hexadecimal altitude data from each relay device into decimal altitude data and transmits it to the monitoring and alarm equipment.

[0058] Please see Figure 6 The diagram shows the communication principle of the water-fall warning device described in this application embodiment. Figure 6As shown, in practical applications, this application provides a fall-over warning device for personnel on offshore oil exploration platforms, including a safety helmet, a distributed signal relay system, and a monitoring and alarm center. First, the safety helmet is mandatory personal protective equipment on offshore oil exploration platforms. By integrating a lithium battery, altimeter (altitude data acquisition card), and 485 communicator into the helmet, all platform personnel become altitude data parameter generators. Second, the area of ​​an offshore platform varies from half to two football fields, making it difficult for a single signal receiver to cover the entire platform. Therefore, in terms of communication structure, this application sets up distributed signal repeaters at various locations on the platform to ensure the reception and transmission of altitude data for all personnel on the platform. Finally, if the altimeter parameter of a safety helmet changes by more than 20 meters within 5 seconds, it can be determined that a person wearing that helmet has fallen overboard, and the monitoring and alarm center receiving the data immediately issues an alarm for the entire platform.

[0059] In one embodiment, the safety helmet further includes a charging port; the charging port is located at the outer opening of the safety helmet, one end of the charging port is connected to an external charging device, and the other end is connected to the battery.

[0060] In one embodiment, the safety helmet further includes an antenna interface; the antenna interface is located at the edge of the safety helmet and is connected to the wireless data transmission module.

[0061] In one embodiment, the battery includes a lithium battery, which is connected to the altitude testing module, the altitude data acquisition card, and the wireless data transmission module, respectively, and supplies power to the altitude testing module, the altitude data acquisition card, and the wireless data transmission module.

[0062] In one embodiment, the wireless data transmission module includes a 485 communicator; the 485 communicator is connected to the altitude data acquisition card.

[0063] In one embodiment, the safety helmet further includes a switch; the switch is disposed at the outer opening of the safety helmet and is connected in series in the power supply line of the battery.
