The invention provides a starting protection method, system and device for a mining dump truck, and the method comprises the steps: setting a whole vehicle controller of the mining dump truck in an ON gear state, reading the state information of a high-voltage part, and judging whether the whole vehicle meets a starting requirement or not; starting signals of the Start gear are continuously input, the vehicle control unit outputs starting control signals, the direct-current isolator is controlled to be powered on, a power source is provided for the starter, and after 0.3 second, the vehicle control unit outputs the starting signals to control the starter and start the engine. Effective data of the hybrid power high-voltage system and the engine are communicated, so that damage to a whole vehicle system caused by interference between the engine and high-voltage equipment parts is avoided; the starter is electrified only before and after starting, so that potential safety hazards caused by long-time electrification of a starting loop of the starter are avoided, and the electrical safety of the mining dump truck is effectively improved.
本发明提供一种矿用自卸车启动保护方法及系统、装置,所述方法包括:将矿用自卸车的整车控制器设置在ON档状态下,读取高压部件的状态信息,判定整车是否满足启动要求;持续输入Start档的启动信号,整车控制器输出启动控制信号,控制直流隔离器通电,给起动机提供电源,0.3秒后由整车控制器输出启动信号控制起动机,启动发动机。本发明通过将混动高压系统和发动机的有效数据之间进行互通,避免了发动机与高压设备部件之间产生干扰对整车系统造成的损害;起动机仅在启动前后带电,避免了因起动机的启动回路长时间通电而带来的安全隐患,有效提高了矿用自卸车辆的电气安全性。
