First of all, high safety performance. After the application of mechatronics technology in construction machinery, the products produced usually have high performance, and at the same time, full-featured, not only with monitoring, alarm function, but also with automatic protection function. If there is an abnormal situation during the operation of the equipment, the mechatronics products may be automatically protected to ensure that the operator and the equipment will not be seriously damaged, so as to ensure the safety of the equipment. Secondly, strong production capacity. Mechatronics equipment in construction machinery, can carry out automatic processing of information, but also can carry out automatic control, can carry out high-precision control and high sensitivity detection. Mechatronics equipment has a control system, equipment operation process, the operator as long as the start of the system, the equipment can be designed to complete all the prescribed action, which not only ensures the efficiency of the product production, but also to ensure that the performance of the product meets the requirements. Plus, the application of automation technology, making the application of mechatronics technology is more valuable. Again, the use of strong performance.

In addition, mechatronics technology can be repeated actions, if the equipment is very advanced, but also automatically select the program, greatly reducing the operator's workload. Finally, the application range is wide. Mechatronics equipment incorporates composite technology, also has certain composite functions, compared with other technologies, can be applied in more fields. Traditional technology is usually a single technology, single function, limited scope of application, mechatronics technology is completely opposite, composite technology and composite function, making the overall function of the equipment is more powerful, can fully meet the needs of users.

In the high performance, the main goal for the application mode of the four high, that is, the application mode of high precision, high efficiency, high reliability and high speed. For example, the new generation of CNC system, which is mainly connected by multi-CPU structure and multi-bus, meets the requirements of the four highs in the application mode, and the application of this system is able to process the multi-tasking operating system at the same time, and realize the production of high-performance products. Miniaturization is a new development goal and direction of mechatronics technology, but also electronic technology as well as mechanical technology to achieve the basis of nanoscale combination. Micro mechatronics products, mainly refers to the size of the nanometer and micron-level products, the volume is generally below 1 cubic centimeter. This kind of micro mechatronics technology products have the characteristics of compactness, energy consumption and flexibility of movement. In the development process of mechatronics technology, intelligence is also a trend in its development. For modern mechatronics technology, its development cannot be separated from the control theory, which is also the difference between mechatronics technology and traditional mechatronics technology, but also the embodiment of intelligence. Intellectualization in the actual production process is mainly reflected in the use of products and functions. Intelligence is mainly combined with artificial intelligence, physiology and computer science and other ideas and methods to imitate human intelligence, so that the scope of application of mechatronics technology and performance functions more modern.
Conclusion
