Intelligent safety helmet

Abstract

The invention relates to an intelligent safety helmet which comprises a battery module, an MCU, a detection module, a positioning module, an LoRaWAN communication module and a voice output module, wherein the battery module supplies electricity to the whole intelligent safety helmet; and the MCU is respectively connected with the detection module, the positioning module, the communication module and the voice output module. The intelligent safety helmet has the advantages that the intelligent safety helmet is provided with the positioning module, so that a manager can directly know the numberof workers in a site, and can effectively know the personnel trends; the intelligent safety helmet is provided with the detection module, so that the manager can know the body condition of each employee in the site, accidents caused by poor body conditions can be prevented, and the employees under the dangerous conditions can be timely found; and the LoRaWAN communication module is used, so that the wireless communication distance is long, the power consumption is low, and the anti-interference performance is high.

Description

technical field [0001] The invention relates to a safety helmet, in particular to an intelligent safety helmet. Background technique [0002] With the development of the Internet and the Internet of Things, all walks of life are undergoing intelligent transformation, and the safety helmet industry is also the same. Different transformations have been made for different application scenarios, such as mine smart helmets based on ZigBee technology, based on ARM11 and DSP cooperative video stream processing technology 3G video safety helmet, etc. [0003] The above-mentioned smart helmets and safety helmets can realize long-distance communication. For mine smart helmets based on ZigBee technology, it has the following disadvantages: 1. ZigBee signals are easily interfered, making the communication quality poor; 2. ZigBee is a short-distance If you want to use the safety helmet of this technology in a large-scale construction site or area, you need to set up a lot of data collec...

Problems solved by technology

[0003] The above-mentioned smart helmets and safety helmets can realize long-distance communication. For mine smart helmets based on ZigBee technology, it has the following disadvantages: 1. ZigBee signals are easily interfered, making the communication quality poor; 2. ZigBee is a short-distance If you want to use the safety helmet of this technology in a large-scale construction site or area, you need to set up a lot of data collection gateways to solve the problem of short distance; 3. There is no international agreement standard, and the development process and In the process of system construction, it is necessary to design and define a huge set of communication protocols to solve a series of problems such as anti-collision and data encryption and decryption.

However, the 3G video helmet based on ARM11 and DSP cooperative video stream processing technology has the following shortcomings. 1. The combination of 3G / 4G and video requires a lot of power consumption. If a small-sized ordinary battery is difficult to maintain Working for a long time, if the battery is large, it will increase the weight, which will bring a lot of burden to the wearer if it exceeds the weight standard of the helmet; 2. 3G / 4G needs to pay additional data traffic fees, especially when adding video transmission Finally, it needs a lot of traffic to support, and it will incur high costs in the end; 3.3G / 4G needs base station coverage set up by operators. In remote construction sites and special environments, the signal is often very poor. At this time, the video signal will not be transmitted
