[0038] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] Embodiment 1

[0040] like Figure 1-8 As shown, the utility model provides a monitoring and early warning device for wearing safety protective gear for aerial work, and the monitoring and early warning device for wearing protective gear includes: a position sensor 11, an alarm module 3 and a host module 2;

[0041] The position sensor 11 is fixedly arranged inside the lock buckle 101 of each buckle 1 on the protective gear to detect the position signal when the lock tongue 102 is locked inside the corresponding lock buckle 101, and send the collected position signal to the host module 2;

[0042] The host module 2 is used to determine the state of the lock tongue 102 according to the received position signal of the lock tongue 102; wherein,

[0043] When it is determined that the locking tongue 102 is not locked in the corresponding lock buckle 101 , the host module 2 triggers the alarm module 3 to send out an alarm signal.

[0044] In the above solution, the model of the host module 2 is: XC3588, rk3588, lntel z590.

[0045] During use, the wearing status of each buckle 1 of the protective gear can be detected by the position sensor 11. When the locking tongue 102 of the buckle 1 is inserted into the lock 101, the position sensor 11 inside the buckle 1 can send the detected position signal to the host module 2. The host module 2 determines that the buckle 1 of the protective gear has been worn. On the contrary, when the position sensor 11 inside the lock 101 of the buckle 1 does not detect the locking tongue 102, it is determined that the protective gear is not worn, and the alarm module 3 is triggered to send an alarm signal to remind the staff to wear the protective gear to avoid the safety problem of falling from a height.

[0046] In addition, the alarm module 3 also includes: a voice speaker and an indicator light; wherein,

[0047] The voice speaker and the indicator light are respectively connected to the host module 2 through wires. When the host module 2 triggers the alarm module 3, the voice speaker of the alarm module 3 sounds and the indicator light flashes to remind the staff to wear protective gear.

[0048] In a preferred embodiment of the present utility model, the position sensor 11 is a magnetic sensor; wherein,

[0049] A magnetic sensor is installed in the lock groove of each lock buckle 101 on the protective gear, and a magnetic block 4 used in conjunction with the magnetic sensor is fixedly provided at the end of all lock tongues 102 used in conjunction with the lock buckle 101.

[0050] In the above scheme, the position sensor 11 is connected to the host module 2 through ZigBee and LoRa technologies, and Zigbee technology is a wireless communication technology used in short distances and low rates. Zigbee used to be called "HomeRFLite" and "FireFly" technologies, which are collectively referred to as Zigbee technology. It is mainly used for data transmission between various electronic devices with short distances, low power consumption and low transmission rates, as well as typical applications with periodic data, intermittent data and low response time data transmission.

[0051] As for LoRa technology, LoRa is actually a wireless platform for the Internet of Things (IoT). Semtech's LoRa chipset connects sensors to the cloud, enabling real-time communication of data and analysis, thereby improving efficiency and productivity.

[0052] In addition, the magnetic sensor can be selected from Hall switches of models such as NSM1071 and NSM1072. The magnetic sensor changes with the change of magnetic field strength through the conduction voltage. The stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. When the voltage is higher than a certain threshold, the switch is closed, and the signal can be transmitted to the host module 2 through ZigBee technology or LoRa technology, and the host module 2 determines whether it is necessary to issue a corresponding alarm signal.

[0053] More specifically, when the lock tongue 102 of the buckle 1 is inserted into the lock buckle 101, the magnetic block 4 approaches the magnetic sensor in the lock buckle 101, and the magnetic field becomes stronger until the magnetic block 4 of the lock tongue 102 is inserted into the lock buckle 101. When the voltage is the highest and higher than the threshold, the magnetic sensor detects the position of the lock tongue 102 and sends the monitored position signal to the host module 2. The host module 2 determines that the lock tongue 102 is correctly inserted into the lock buckle 101, thereby determining that the buckle of the protective gear is worn correctly. On the contrary, when the lock tongue 102 is not locked in the corresponding lock buckle 101, the host module 2 triggers the alarm module 3 to send an alarm signal. To warn the staff that the protective gear is not worn.

[0054] Therefore, by processing the output signal of the magnetic sensor, it is possible to determine whether the seat belt is fastened. If the magnetic sensor detects a change in the magnetic field, it means that the seat belt is fastened; if no change is detected, it means that the seat belt is not fastened or is unfastened. In this way, the status of the seat belt can be monitored in real time to ensure that the high-altitude workers use the seat belt correctly during the operation, thereby improving construction safety.

[0055] In a preferred implementation manner of the utility model, the protective gear comprises: a safety helmet, a safety belt and a hook.

[0056] In the above scheme, the lock slots of each lock buckle 101 on the helmet and the full belt are respectively equipped with magnetic sensors, and the ends of all lock tongues 102 used in conjunction with the lock buckle 101 are respectively fixed with magnetic blocks 4 used in conjunction with the magnetic sensors;

[0057] The hook mouth of the fixed part of the hook is also equipped with a magnetic sensor, and the movable part of the hook is fixedly provided with a magnetic block 4 adapted to the magnetic sensor, and the magnetic block 4 can be against the magnetic sensor of the hook.

[0061] The processing module 8 is mounted on the host module 2, and is used to process the electrical signal sent by the electronic beacon station 6 to obtain the RSSI value of the host module 2 and the electronic beacon station 6, and calculate the distance value between the host module 2 and the electronic beacon station 6 according to the RSSI value, and send the calculated distance value to the host module 2, and the host module 2 makes a judgment;

[0062] When the distance value calculated by the processing module 8 reaches a preset threshold, the host module 2 triggers the alarm module 3 to send a prompt signal to prompt the staff to enter the dangerous working area.

[0063] In the above solution, the host module 2 is provided with a GPS positioning system for obtaining the high-precision position of the dangerous operation area and the position information of the host module 2.

[0064] The signal receiver 7 is also mounted on the host module 2. The host module 2 receives the electrical signal generated by the electronic beacon station 6 through the signal receiver 7, and sends the received electrical signal to the processing module 8. The RSSI value of the host module 2 and the electronic beacon station 6 is obtained through the processing module 8, and the RSSI value is substituted into the function of the RSSI value and the distance relationship to calculate the distance from the target to the beacon station. The host module 2 makes a judgment. When the distance value calculated by the processing module 8 reaches a preset threshold, the host module 2 triggers the alarm module 3 to send a prompt signal to remind the staff to enter the dangerous working area and wear protective gear.

[0065] In a preferred embodiment of the present invention, the calculation formula of the processing module 8 is:

[0066] RSSI = P tx -10×n×log 10 (D)+K)-S rx

[0068] In a preferred embodiment of the present invention, the wearable monitoring and early warning device further comprises: a wireless communication module 10; wherein,

[0069] The host module 2, the dangerous area warning module 5, the position sensor 11 and the alarm module are connected via a wireless communication module 10 for wireless transmission of signals between the modules.
