Description
技术领域technical field
本发明涉及无人机技术领域，具体为一种无人机电池管理放电防打火方法。The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for managing discharge and preventing sparking of unmanned aerial vehicles.
背景技术Background technique
随着科学技术的日升月异的发展和人们生活水平的提高，以及人口老龄化和劳动力缺少，越来越多的岗位被自动化设备所替代，但是在野外作业的工作越来越多的岗位也被无人机所替代，比如地震救灾，森林火灾，洪水救灾等救灾现场航拍技术，就是采用无人机技术，还有电力领域的高压线野外巡线技术也是采用无人机航拍技术，以及农业领域的植被喷洒农药技术也是应用无人机技术，无人机分电动无人机和燃油无人机，而燃油无人机价格太高，在日常生活和工作中用不起，只有电动无人机采用二次锂电池的无人机，价格低，轻便，便于应用于各个领域；然而二次锂电池固有的特性，充电不能充的太高，放电不能放的太低，这就需要一定锂电池管理系统。而在日常使用过程中，电池跟无人机对接时会出现接电瞬间打火现象，这种打火现象虽然不是致命的，但是严重产品使用的寿命和品质，在打火过程中，电弧会对接插件进行氧化，导致接触不良和内阻增大等一系列问题，这就会对实际使用者的造成一定的影响，为了增加产品寿命和品质，目前大部分采用把接插件做的牢固镀金来处理和预充电方式来处理，这样进成本增加，没有从根本上解决问题，只是治标不治本的解决办法，预充电方式增加成本，而且可靠性，发热危险系数高，有可能引起电池燃烧的安全事故；为此，我们提出一种无人机电池管理放电防打火方法。With the rapid development of science and technology and the improvement of people's living standards, as well as the aging population and the shortage of labor force, more and more jobs are replaced by automation equipment, but more and more jobs are done in the field It is also replaced by drones, such as earthquake relief, forest fires, flood relief and other disaster relief scene aerial photography technology, which uses drone technology, and high-voltage line field inspection technology in the power field also uses drone aerial photography technology, and agricultural Vegetation spraying pesticide technology in the field also applies UAV technology. UAVs are divided into electric UAVs and fuel UAVs. Fuel UAVs are too expensive to be used in daily life and work. Only electric UAVs are available. The unmanned aerial vehicle using the secondary lithium battery is low in price, light and easy to apply in various fields; however, due to the inherent characteristics of the secondary lithium battery, the charge cannot be charged too high, and the discharge cannot be discharged too low, which requires a certain amount of lithium battery management system. In the daily use process, when the battery is docked with the drone, there will be a phenomenon of sparking at the moment of power connection. Although this sparking phenomenon is not fatal, it is serious for the life and quality of the product. During the sparking process, the arc will Oxidation of connectors will lead to a series of problems such as poor contact and increased internal resistance, which will have a certain impact on actual users. In order to increase product life and quality, most of the connectors are firmly gold-plated at present. Treatment and pre-charging method, which increases the cost and does not fundamentally solve the problem, but only a solution to the symptoms, not the root cause. The pre-charging method increases the cost, and the reliability and high risk factor of heat generation may cause the battery to burn. Accidents; for this reason, we propose a UAV battery management discharge anti-sparking method.

Unplug the man-machine control system R1, if unplugged, the current source Y1 will be disconnected, and the micro-control system C1 will record it; wait for the next time the secondary lithium battery B1 is connected to the UAV control system R1 again, when the second When the secondary lithium battery B1 is connected to the UAV control system R1 again, the current source Y1 will be turned on again. When the current source Y1 is turned on again, it will send a signal to the micro-control system C1, and the micro-control system will determine that the battery B1 is connected to the control system R1. The UAV control system R1 has been connected, and the micro-control system will turn on the discharge MOS tube S1 with a delay, so that there will be no current generated when the battery B1 contacts the UAV control system R1, so as to realize the anti-discharge The phenomenon of ignition.
