Description

Technical Field

[0001] This utility model relates to the field of smart safety helmets, and more specifically, to smart safety helmets in environments without a network connection. Background Technology

[0002] A smart safety helmet is an intelligent wearable device that combines traditional safety protection functions with Internet of Things (IoT) technology. It is an advanced product combining industrial IoT and wearable technology, primarily used in high-risk work scenarios such as firefighting, disaster relief, industry, construction, power, mining, and railway operations. Based on a standard safety helmet, it integrates electronic sensors, communication modules, and data processing units to achieve active safety protection, real-time monitoring, and human-machine interaction, significantly improving operational safety and management efficiency.

[0003] However, the functionality of smart safety helmets is highly dependent on a stable network environment, requiring real-time collaboration between the management terminal and the device to fully leverage their intelligent advantages. In scenarios where public network signals are scarce or weak, such as in industry, mines, building basements, emergency rescue, and remote areas, the real-time communication and collaboration functions of smart safety helmets will be severely limited. Data collected on-site, such as video and environmental sensor data, cannot be transmitted back to the management terminal in real time, leading to a significant reduction in data synchronization and storage efficiency. Furthermore, due to the random and temporary nature of many application scenarios, it is difficult to pre-deploy dedicated networks. The built-in Bluetooth communication function of the safety helmet has limited bandwidth, making it difficult to support the rapid transmission and real-time preview of large amounts of data such as videos and photos, failing to meet the real-time collaboration needs of scenarios such as inspection and evidence collection, and failing to guarantee the quality of video and photo evidence. Therefore, there is an urgent need for a smart safety helmet for environments without a network connection. Utility Model Content

[0004] This invention provides a smart safety helmet for environments without a network, solving communication problems in areas without a public network. In scenarios such as industry, mines, basements, and emergency rescue, where there is no public network or poor signal, it achieves point-to-point (P2P) or local area network (LAN) interconnection between the safety helmet and on-site management terminal devices (such as mobile phones, tablets, and local servers) through a self-organizing Wi-Fi hotspot, ensuring uninterrupted real-time communication. It eliminates dependence on carrier networks, ensuring the normal operation of functions such as instant voice calls, text messages, and emergency alarms at the work site. It features no network dependency, rapid deployment, flexible connectivity, multi-functional integrated control, and efficient data transmission.

[0005] To achieve the above objectives, this utility model provides a smart safety helmet for environments without network connectivity, comprising a smart safety helmet and a field management terminal device. The smart safety helmet includes a Wi-Fi module, a video acquisition device, an environmental data acquisition device, a positioning device, a control module, and a battery and power management module.

The outer shell of the smart safety helmet is printed or affixed with a QR code label containing the Wi-Fi hotspot name and password. The field management terminal device can scan the QR code label, enabling the smart safety helmet to establish a communication transmission link with the field management terminal device through its built-in Wi-Fi module. The field management terminal device can send control commands to the smart safety helmet and receive data.

[0006] Specifically, it also includes an earphone and a microphone; the earphone is located on both sides of the smart helmet, and the microphone is connected to the earphone; the earphone is electrically connected to the control module.

[0027] like Figure 1 and Figure 2As shown, this embodiment of the invention provides a smart safety helmet for use in environments without a network, including a smart safety helmet 1 and a field management terminal device. The smart safety helmet 1 includes a Wi-Fi module, a video acquisition device 4, an environmental data acquisition device, a positioning device, a control module, and a battery and power management module. The Wi-Fi module, control module, and battery and power management module are built into the top of the smart safety helmet 1. The video acquisition device 4 is embedded in the front of the smart safety helmet 1. The environmental data acquisition device and positioning device are installed on the shell 2 near the brim of the helmet. The Wi-Fi module, video acquisition device 4, environmental data acquisition device, and positioning device are respectively connected to the control module. The battery and power management module is connected to the control module to power the entire smart safety helmet 1. A QR code label containing the Wi-Fi hotspot name and password is printed or affixed to the outer shell of the smart safety helmet 1. The field management terminal device can scan the QR code label, enabling the smart safety helmet 1 to establish a communication transmission link with the field management terminal device through its built-in Wi-Fi module. The field management terminal device can send control commands to the smart safety helmet 1 and receive data.

[0028] The Wi-Fi module uses a wireless chip with the model number MT7615NWI-FI.

[0029] The video acquisition device 4 includes a camera and a fill light.

[0030] The environmental data acquisition device includes a gas sensor, a temperature and humidity sensor, and a smoke sensor.

[0031] The positioning device uses the BeiDou positioning system.

[0032] The control module uses the LPC1778 based on the ARM Cortex-M3 core.

[0033] On-site management terminal equipment includes, but is not limited to, smartphones, tablets, and local servers, supporting HTTP communication and QR code scanning; it is equipped with a Wi-Fi module and supports 2.4GHz / 5GHz dual-band connection.

[0034] The smart helmet 1 also includes an earphone and a microphone. The earphone is located on both sides of the smart helmet 1, and the microphone is connected to the earphone. The earphone is electrically connected to the controller. It also includes a flashlight, a warning light, and a laser light, which are each electrically connected to the controller.

[0035] The battery and power management module can query the battery level and power the smart helmet 1.

[0036] The working principle and usage method of this embodiment are as follows:

[0037] (1) Smart helmet activation:

[0038] After power-on, the control module activates the Wi-Fi module, generates a hotspot named after the device ID, and enables WPA2-PSK encryption by default.

[0039] (2) The connection of the on-site management terminal equipment can be carried out in two ways:

[0040] Method 1 (Manual Connection): The on-site management terminal device opens the Wi-Fi settings interface and scans for available networks; the user selects the SSID (Wi-Fi hotspot name) corresponding to the target safety helmet and enters the preset password to complete the connection.

[0041] Method 2 (Scan QR code to connect):

[0042] The on-site management terminal device can scan the QR code on the shell of the smart safety helmet 1; the on-site management terminal device can automatically parse the SSID and password in the QR code and trigger the system Wi-Fi interface to complete the connection.

[0043] Once the on-site management terminal device successfully connects to the Wi-Fi hotspot of the smart safety helmet 1, the two form the same wireless local area network. In this network, the smart safety helmet 1 acts as the gateway node, and its IP address is automatically assigned as the gateway address of the local area network.

[0044] (3) On-site management terminal equipment control:

[0045] The on-site management terminal equipment sends control commands to the smart safety helmet 1. These control commands include, but are not limited to, waking up the smart safety helmet 1, switching on and off the flashlight and adjusting its brightness, switching on and off the laser light and the warning light, taking photos, recording videos, making emergency calls, checking battery level, adjusting the volume of the earphone, and uploading data.

[0046] Data interaction: The on-site management terminal device and the smart safety helmet 1 perform high-speed transmission of large-capacity data. The display function built into the on-site management terminal device in this embodiment of the utility model can realize real-time preview, including real-time preview of camera images, remote control of taking photos / recording videos, browsing / downloading / deleting stored photos and video files, and multi-sensor data synchronization.

[0047] Multi-device collaboration: Supports simultaneous access of multiple field management terminal devices to meet human-machine collaborative operation scenarios with high bandwidth requirements.

[0048] This utility model embodiment uses a Wi-Fi module to provide higher transmission bandwidth, support the rapid synchronization of high-definition video and multi-sensor data, and allow multiple devices to access simultaneously, which can meet the high load requirements such as real-time video preview and multi-person collaborative operation.

[0049] Furthermore, this embodiment of the invention is adaptable to temporary and random scenarios, without relying on pre-deployed dedicated networks. The safety helmet can autonomously create Wi-Fi hotspots or form a mesh self-organizing network with other devices, flexibly responding to sudden tasks or mobile operation needs. It reduces infrastructure deployment costs and is especially suitable for dynamic scenarios such as emergency rescue and temporary construction.

[0050] This utility model embodiment utilizes Wi-Fi to implement existing hotspot collaboration technology, achieving "offline intelligence" for smart safety helmets in environments without a network. It solves the pain points of traditional solutions such as reliance on public networks, insufficient Bluetooth performance, and difficulties in temporary networking, significantly improving the reliability, flexibility, and collaboration efficiency of the device in complex industrial scenarios.
