The invention aims at providing a safety reminding device suitable for aerial work. The device is used for achieving the technical purposes that the wind speed is measured after a construction workerreaches a certain altitude, and alarm reminding is carried out when the wind speed reaches a certain value so that the construction safety of the construction worker can be ensured. The safety reminding device suitable for the aerial work includes a safety helmet body, a control system, an altitude measurement system, an encapsulating box system, a wind speed measurement system and an alarming system, wherein the altitude measurement system, the encapsulating box system, the wind speed measurement system and the alarming system are electrically connected with the control system. The safety reminding device has the advantages that by arranging the wind speed measurement system and the altitude measurement system on the safety helmet body, the wind speed at the certain altitude can be measured, and the construction worker can be reminded through the alarming system when the wind speed reaches the certain value to prevent the occurrence of an accident.
