The invention relates to the technical field of vehicle-mounted equipment control, in particular to an engineering machinery electric air conditioner control method and device, engineering machinery and a medium. A control mechanism in the engineering machinery electric air conditioner control system is in communication connection with an air conditioner mechanism, an air blower and a PTC (Positive Temperature Coefficient) simultaneously, and at least two relays are in parallel communication connection between the PTC and the control mechanism. The target control gear of the PTC is set by using the current temperature difference value between the current return air temperature in the cab and the preset temperature, the current air speed gear of the air blower and the current environment temperature; the target control gear of the PTC can be determined at the same time according to the difference value between the return air temperature and the preset temperature, the current air speed index and the current environment temperature, and the function of accurately controlling the gear corresponding to the target control gear of the PTC is achieved.
本发明涉及车载设备控制技术领域,特别涉及一种工程机械电动空调控制方法、装置、工程机械及介质,将工程机械电动空调控制系统安装在工程机械的驾驶室内,让工程机械电动空调控制系统中的控制机构同时与空调机构、鼓风机以及PTC通讯连接,同时再将至少两个继电器并联通讯连接于PTC与控制机构之间,利用驾驶室内的当前回风温度与预设温度之间的当前温度差值、鼓风机的当前风速档位以及当前环境温度,对PTC的目标控制档位进行设定,能够根据回风温度与预设温度之间的差值、当前风速指标以及当前环境温度同时确定PTC的目标控制档位,实现了对PTC的目标控制档位所对应的档位进行精准控制的功能。
