Aircraft safety detection management device and safety control system

Abstract

The present invention discloses an aircraft safety detection management device. The aircraft safety detection management device comprises N battery packs, N BMS modules corresponding to the battery packs and a BMS host; the N battery packs are arranged in parallel; each of the battery packs comprises a plurality of batteries; the BMS modules acquire the monitoring data of the battery packs, wherein the monitoring data contain the temperature and electric quantity of the battery packs and the individual voltage of each battery; and after an aircraft takes off, the BMS host compares the monitoring data with a first preset value, a second preset value and a third preset value and judges whether the monitoring data exceeds the first preset value, the second preset value and the third preset value so as to output alarm signals of corresponding levels. According to the aircraft safety detection management device of the invention, the battery packs are arranged independently, each battery pack is provided with an independent module, and therefore, each battery pack can be monitored independently, the service lives of the battery packs can be prolonged, and the safety use degrees of the battery packs can be improved; and grading detection is performed according to the electric quantity and temperature of the battery packs and the individual voltage of each battery, so that the corresponding alarm signals can be outputted, and therefore, the use safety of the aircraft can be improved. The invention also discloses a corresponding safety control system.

Description

technical field [0001] The invention relates to an aircraft, in particular to the safety detection and control of the aircraft. Background technique [0002] Aircraft, especially light-weight aircraft, do not have an independent power management system (BMS) when in use, and directly connect the battery packs in series with the corresponding drive motors, which not only makes it difficult to guarantee the life of the battery packs, but also cannot be correctly estimated The power and voltage of all battery packs, and the temperature of the monitored batteries are often crashed due to battery shortage or overheating damage, which poses a safety hazard to human use. [0003] Therefore, there is an urgent need for an aircraft safety detection and control system that can solve the above-mentioned problems. Contents of the invention [0004] The purpose of the present invention is to provide an aircraft safety detection management device and a safety control system, which can ...
