Intelligent terminal and remote calling method used for electro-hydraulic control system as well as engineering machinery

Abstract

The invention relates to the field of engineering machinery, and discloses an intelligent terminal used for an electro-hydraulic control system. The intelligent terminal comprises a data transmissionmodule and a master control module, wherein the data transmission module is used for receiving site operation request of a controller of the electro-hydraulic control system; the master control moduleis used for calling corresponding application according to the site operation request of the controller; and field operation is performed according to the application, and the data transmission module is further used for returning field operation results to the controller. The intelligent terminal does not need to upgrade the original electro-hydraulic control system, can reduce intelligent modifying development period and cost of the electro-hydraulic control system, and further can effectively improve operation ability of the electro-hydraulic control system on the basis of guaranteeing stability of the original electro-hydraulic control system.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to an intelligent terminal for an electro-hydraulic control system, a remote calling method, and an engineering machine including the intelligent terminal for an electro-hydraulic control system. Background technique [0002] With the development of intelligence in construction machinery products, the electro-hydraulic control system needs to carry more modern control algorithms such as adaptive control, artificial neural network, and fuzzy control, which requires upgrading the online and real-time on-site calculation of the existing electro-hydraulic control system ability. The existing methods to improve the on-site computing capability of the electro-hydraulic control system include: (1) update the controller and use a controller with higher computing performance; (2) use higher-performance smart sensors and smart actuators, Reduce the requirement on the computing po...

Problems solved by technology

[0003] The above-mentioned methods of improving the on-site computing capability of the electro-hydraulic control system have the following disadvantages: (1) The controller with high computing performance is expensive, and updating the controller will greatly increase the development cost; (2) Increase the complexity of the original sensors and actuators. In addition, due to the limitations of the installation and volume of sensors and actuators, they cannot be embedded with high-performance computing units, and the improvement effect is limited; (3) The modern control algorithm is simplified as much as possible, so that it can run on existing control systems. On the controller, this will not only increase the load on the controller, but also fail to meet the truly intelligent requirements of the product
