In the above technical solution, the monitoring module is configured to monitor a working condition of the load module, and transmit the monitored working condition information of the load module to the I/O port of the task processing through the I/O port of the information interaction module. The task processor is used as a control center of the electro-hydraulic servo system, processes the acquired working condition information of the load module, and transmits control information of the load module to the information interaction module through the I/O port. It can be understood that, because the loads included in the load module are various, in order to ensure that the control information corresponds to the controlled load, the electro-hydraulic servo system needs to directly input the control information to the load module through the driving module to prevent the control information from being disordered. Therefore, the control information of the load module is generated by the task processor, is used as a relay through the information interaction module, and is directly driven by the driving module to respond to the control information. The monitoring module monitors the response condition, namely the working condition, of the load module and transmits the working condition information of the load module obtained by monitoring to the I/O port of the task processing through the I/O port of the information interaction module. It will be appreciated that the electro-hydraulic servo system described above is in fact a closed loop control system. The electro-hydraulic servo system has the feedback control capability, the load working condition monitored by the monitoring module is actually a feedback factor in the feedback control process, and the control object in the feedback control process is actually a load module. Therefore, the load module controlled by the electro-hydraulic servo system has the characteristic of accurate action.

The CAN protocol and the CANopen protocol are communication protocols constructed in a control area network, and are mainly characterized by stable physical layer, reliable link layer and high information transmission speed. Therefore, the process that the monitoring module transmits the working condition information of the load module to the information interaction module and the process that the information interaction module transmits the control information of the load module sent by the task processor to the driving module can be guaranteed, and the processes are efficient and reliable.
