Hydraulic excavator, hourmeter tamper-proofing method and system thereof and electronic monitor
The invention relates to a hydraulic excavator, a hourmeter tamper-proof method and system thereof and an electronic monitor. The tamper-proofing method for the hour meter of the hydraulic excavator comprises the following steps: under the condition that the count of the hour meter changes, an electronic monitor judges whether the hour meter has suspicious behaviors or not; under the condition that suspicious behaviors exist in the hour meter, the electronic monitor actively drives the rotating speed of an engine to change, and the engine of the hydraulic excavator is a mechanical engine; the electronic monitor obtains the current engine rotating speed; the electronic monitor judges whether the current engine rotating speed is consistent with the set rotating speed or not; when the current engine speed is inconsistent with the set speed, the electronic monitor determines that the current hour count is a first invalid count. According to the method, tampering prevention of the hourmeter of the hydraulic excavator based on the mechanical engine can be achieved, and tampering of the hourmeter is effectively avoided.
本公开涉及一种液压挖掘机及其小时计防篡改方法和系统、电子监控器。该液压挖掘机小时计防篡改方法包括：在小时计计数变化的情况下，电子监控器判断小时计是否存在可疑行为；在小时计存在可疑行为的情况下，电子监控器主动驱动发动机转速变化，其中，所述液压挖掘机的发动机为机械式发动机；电子监控器获取当前发动机转速；电子监控器判断当前发动机转速是否与设定转速一致；在当前发动机转速与设定转速不一致的情况下，电子监控器判定当前小时计计数为第一无效计数。本公开可以实现基于机械式发动机的液压挖掘机小时计的防篡改，有效地避免小时计被篡改。
