At present, the state has strict regulations on safety guarantee of high-altitude operation, an operator needs to wear a safety belt with a safety rope when performing high-altitude operation, and the operator fixes a belt body on the body and fixes a hook at the other end of the belt body through the safety rope.
In the prior art, a safety belt worn for work high above the ground has the functions of oxygen detection and height detection. However, such a seat belt does not have the function of checking the surrounding environment of the operator and monitoring the physical condition; therefore, in the process of high-altitude operation, if the body of an operator is abnormal or toxic gas exists in the environment, when the weather condition is not good, the operator is required to communicate with the remote platform independently, the safety belt has great limitation in function, more tools for controlling the operator not to fall off high altitude are used, and the functions of monitoring the environment such as communication and the like are not provided. Although the aerial workers can also be equipped with some environment monitoring or communication devices for aerial work, the devices are independent, the common use of the collected different data cannot be realized, and moreover, the devices need to be fixed on the body of the aerial workers, and accidents always occur in a conventional fixing mode, such as: often, the mobile phone or food of the overhead operator falls off due to carelessness of the operator, which can cause the communication obstruction of the operator.
