The invention belongs to the field of engine starting design, and relates to a method for preventing overtemperature in a ground simulation auxiliary starting process, which comprises the following steps that: ground inspection equipment receives a wheel load signal in real time and judges, and when the ground simulation state is judged, the ground inspection equipment sends ground auxiliary starting simulation inspection to a controller; the controller reduces the exhaust temperature limit value of the engine; when it is judged that the engine is in the air simulation state, the ground detection device cancels sending of the ground auxiliary starting simulation inspection signal, and when the controller does not receive the ground auxiliary starting simulation inspection signal within a certain time, the exhaust temperature limit value of the engine is increased. And overtemperature and even burnout of the engine caused by incomplete simulation auxiliary starting input conditions or other abnormal conditions can be effectively avoided. The use experience of outfield users is greatly improved, and the operation risk and burden of the users are reduced.
本申请属于发动机起动设计领域,为一种防止地面模拟辅助起动过程超温的方法,包括:地面检查设备实时接收轮载信号并进行判断,当判断处于地面模拟状态时,地面检查设备发出“地面辅助起动模拟检查”至控制器,控制器降低发动机的排气温度限制值;当判断处于空中模拟状态时,地面检测设备取消发送“地面辅助起动模拟检查”信号,控制器在一定时间内未接收到“地面辅助起动模拟检查”信号时,提高发动机的排气温度限制值。可以有效的避免由于模拟辅助起动输入条件不完整或者其他异常情况导致的发动机超温,甚至烧毁。极大的提升了外场用户的使用体验,降低了用户的操作风险和负担。
