随着科学技术水平的不断提高,高技术产品进入了各行各业各种产品。由于建筑工程发展的需要,高技术也开始在建筑工程机械行业中逐渐普及,许多工程机械已向机电信一体化方向发展。国外许多工程机械都已开发了机电一体化产品或部件。例如装载机的传动系带自动换档的变速箱,可根据工作及行驶的状态而由微机自行决定是升档还是降档,明显提高了工作效率,降低了运行成本。又如大型液压挖掘机上配备机载的微机控制运行状态监测及故障诊断系统,能及时监测各部工作参数并能分析诊断故障的部位,大大提高了机械的使用效率,延长了机械寿命。由于这些产品在技术上占优
With the continuous improvement of science and technology, high-tech products have entered various products in all walks of life. Due to the need for the development of construction projects, high technology has also begun to gain popularity in the construction and construction machinery industry. Many construction machinery have been developed toward the integration of aircraft telecommunications. Many foreign engineering machinery have developed mechatronic products or components. For example, the loader’s transmission is automatically shifted gearbox, according to the state of work and driving by the computer to determine whether to upshift or downshift, significantly improve the efficiency and reduce operating costs. Another example is a large-scale hydraulic excavator equipped with on-board microcomputer control operation status monitoring and fault diagnosis system that can timely monitor the working parameters of various departments and can analyze the fault diagnosis, greatly improving the efficiency of the use of the machine, extending the mechanical life. Because these products are technically dominant
