[0002] In recent years, there are more and more smart wearable devices, among which smart bracelets are the most popular among consumers and manufacturers. Now the functions of smart bracelets are becoming more and more powerful, integrating the functions of multiple devices. Basically, they are equipped with functions such as displaying time, measuring heart rate, and counting steps. Users can see their heart rate and steps at any time and place. However, the current smart bracelets are not highly professional. Especially, there is no smart bracelet for miners or those engaged in the mining industry, which cannot ensure the safety of underground workers.

[0003] In related technologies, traditional mine-use personnel positioning identification cards only have the positioning function. There are three common types of wireless positioning identification cards based on radio frequency technology, Zigbee technology, and ultra-wideband technology. However, the common carrying method of mine-use identification cards is to be fixed on the belt or safety helmet, and the charging method is to use a power adapter for charging. The carrying method is inconvenient and easy to lose. Underground workers can only send a distress signal by long pressing the alarm button in the identification card when they subjectively feel an emergency. The warning ability for physical problems and the timeliness of rescue are relatively poor. Utility Model Content

Detailed implementation manners

[0028] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0029] Traditional mine personnel positioning identification cards have the following disadvantages:

[0030] 1) Traditional personnel positioning identification cards only have positioning functions and cannot monitor human body sign information. They can only upload location and alarm signals, and cannot enable the wearers and the duty personnel in the mine dispatching center to understand human body sign information.

[0031] 2) Underground workers can only send out a distress signal by long pressing the alarm button in the identification card when they subjectively feel an emergency situation themselves. The warning and rescue timeliness for physical problems are relatively poor.

[0032] 3) The identification card has no display device and cannot display the power consumption in real time and in detail. Only when the battery is nearly exhausted, it will flash a red light to remind the battery health status. Therefore, underground workers often ignore the charging situation of the identification card, resulting in the situation that even if worn, it cannot be used normally underground.

[0033] 4) The appearance size of the mine identification card is relatively large. The common carrying method is to fix it on the belt or safety helmet, which is not portable and is easy to lose.

[0034] 5) The mine identification card can only be used when going down the mine. It has no function usually and can only be stored in a fixed place, which is not easy to keep.

[0035] Next, the mine intelligent bracelet of the embodiment of the present application will be described with reference to the accompanying drawings. Specifically, Figure 1 It is a structural block diagram of a mine intelligent bracelet provided by the embodiment of the present application.

[0036] As Figure 1 shown, the mine intelligent bracelet 100 includes: a bracelet body 1, a strip structure 2, a UWB module 3, a biological parameter acquisition sensor 4, and a processor 5.

[0038] It can be understood that the embodiment of the present application can locate the personnel position through the UWB module 3 arranged inside the bracelet body 1 and acquire the biological parameters of the personnel through the biological parameter acquisition sensor 4. The processor 5 triggers an alarm signal based on the biological parameters acquired by the biological parameter acquisition sensor 4, locates the personnel position through the UWB module 3 and the positioning base station, and sends the alarm signal and the personnel position to the target device outside the mine through the UWB module 3, which can timely identify the abnormality of the personnel, timely feedback the position and biological parameter information to the device outside the mine, so as to improve the rescue rate and ensure the safety of the personnel in the mine.

[0039] Specifically, the UWB module 3 can implement the ranging function with the positioning base station and has a high-precision positioning function.

[0040] The processor 5 uses the NRF52832 chip as the central data processing unit of the bracelet. It is not only responsible for all the functions of an ordinary bracelet, but also responsible for receiving the data information and alarm buttons of the transceiver part of the UWB module 3 and displaying them on the display screen, and performing human-computer interaction operations according to the panel buttons.

[0041] The bracelet can upload personnel positioning information and human body sign information. When the bracelet is within the range of the personnel positioning sub-station, the bracelet conducts ranging communication with the positioning sub-station and uploads the bracelet information to the positioning sub-station. The bracelet can also monitor information such as human heart rate, blood pressure, and steps, and upload it to the sub-station.

[0042] In the embodiment of the present application, as Figure 3 shown, the UWB module 3 is a UWB circuit.

[0043] It should be noted that the UWB wireless transceiver uses a DW1000 chip, with a working frequency band of 3.75 - 4.25 GHz; transmission power: (-30 - 20) dBm (not greater than 1 mW); receiving sensitivity ≤ -80 dBm; communication distance with the card-reading sub-station is greater than 1 m.
