Detailed Description
Fig. 1 a-1 d show a front view, a side view, a perspective view and an exploded view, respectively, of a safety line locator 1 of a system according to the invention. In an embodiment, the safety line locator 1 is constructed with a housing 2, a main board 3 with UWB and LoRaWAN modules, and a battery 4.
Fig. 2 shows a hand-held marking device 5 of the system according to the invention. In an embodiment, the handheld marking device 5 is configured with a back panel 6, a rear frame 7, a battery 8, a front frame 9, a display unit 10, a display screen 11, and a main panel 12.
FIGS. 3 a-3 f show a right side view, a left side view, a front view, a top view, a perspective view, and an exploded view, respectively, of the smart clasp 13 of the system according to the present invention. In this embodiment, the smart clasp 13 is constructed with a back plate 14, a gyroscopic sensor 15, an LED and buzzer 16, a battery 17, a main board 18 with a microcontroller MCU, a UWB communication module and a LoRaWAN/NBIOT/5G communication module, a bezel 19 with a vibration sensor and a voltage sensor, an outer case 20 and a top case 21.
The smart clasp 13 is an ergonomically designed clasp with 3 functions:
1. the physical shell of the device is held by a user (high-altitude operator);
2. a protection function for the electronic circuit; and
3. the mechanical function of the safety rope fixing device is buckled.
The distance between safety rope intelligence clip and the safety rope fixing device can set up through LoRaWAN or WIFI dynamically. Typically, the distance is in the range of 25cm to 45 cm.
Information is transmitted to the LoRa network via UWB location technology, which is also a communication means between the seat belt smart buckle, the seat belt tether locator, and the UWB base station (not shown). A UWB module 18 mounted in the seat belt smart clasp 13 processes UWB signals exchanged from the safety rope positioner 1 or from a UWB base station. The UWB base station has the following functions: 1. tracking the position of the intelligent clasp of the safety belt, and then transmitting a position signal back to a cloud end or a local edge server so as to record logs and track a moving path; 2. other information is transmitted from the seat belt smart clasp to the aerial work management terminal, such as battery status of the safety line locator, line orientation and vibration information, etc. At the same time, the UWB module of the smart buckle provides reference information for determining whether the seat belt positioner is in close proximity to the smart buckle of the seat belt, thereby determining whether the seat belt is properly latched at the fixed end of the seat belt. If the work high above ground is only limited to a small area, e.g. an elevator platform, then no UWB base station is needed. The system according to the invention processes the information that the safety belt approaches the safety rope fixing device, and the information detected by other internal sensors of the intelligent clasp of the safety belt is transmitted to the aerial work management terminal through LoRaWAN network, 5G network or NB-IOT network.
Fig. 4 shows a method according to the invention for securing work high above ground, implemented using a system according to the invention, wherein the method comprises the following steps: when the operator opens the safety belt, the system displays the existence of the safety belt; the system detects whether a seat belt is in a hazardous area; detecting whether a distance of the seat belt from a seat belt positioner is within a predetermined distance range when the seat belt is in a hazardous area; detecting whether the seat belt is buckled within a predetermined time when the seat belt is in a hazardous area and a distance from the safety line locator is not less than a predetermined distance; when the safety belt is in a dangerous area and the distance from the safety rope positioner is not less than a preset distance and the safety belt is not locked in a preset time, sending positioning information and safety belt state to a high-altitude operation management terminal and making a real-time notification.
Fig. 5a and 5b show an embodiment using the method according to the invention. In fig. 5a, the worker is in a hazardous area and the belt smart clasp detects that it is not less than 45cm from the belt fixed end and is not latched for more than 1 minute, triggering an alarm. In contrast, referring to fig. 5b, when the seat belt smart hook detects a distance of less than 45cm from the fixed end of the safety line, although the operator is in a hazardous area, no alarm is triggered.
Although the invention has been further elucidated and described in detail by means of preferred embodiments, the invention is not limited to the disclosed examples and a person skilled in the art will be able to derive further variants therefrom without departing from the scope of protection of the invention.
