Recently, with the continuous advancement of network technology, it has created a good condition for the development of remote monitoring technology. Various systems based on network technology have been put into industrial practice, and they greatly promote the flexibility and open of enterprise production. So many Production patterns have been born such as remote network control,computer integrated manufacture etc. The mobile robot remote monitoring system based on Internet will provide a new development direction and hot spot for mobile robot.The main purpose of this paper is to design and implement a remote monitoring of mobile robot platform based on Internet. By means of the platform, operators on the network client can monitor the movement of the mobile robot on web site. Specifically for the key problems of remote monitor on Internet: such as real-time,security and reliability of network, this paper gives a solution of mobile robot network remote monitor. In the field of real-time, the network communication is realized between server and client by Winsock based on TCP/IP protocol with C/S structure, through ultrasonic sensor, the dynamic real-time map has been built to simulate the environment around mobile robot, then even though under the condition of low bandwidth, the running situation and the circumstance of mobile robot can be monitored. In the field of security, using the information encryption technique and three layers of user-role-authority structure not only to warrant reliability and security of control information can also be hierarchical control. It has been achieved the close integration between the role and the authority, systemic security also be enhanced. In the field of reliability, introducing multi-threaded mechanism, assigning a thread for each client on the server of the mobile robot network remote monitoring, so even if a client exchanges information with server, other clients can also exchange information with the server or other operations, it prevents communication conflict and network blocking, improving the reliability of the system communication.In order to simulate experiment, mobile robot local autonomous navigation uses landmark navigation, this paper analyzed the course of image processing and effectively extracted the shape feature of image to identify target landmark and presented the specific implementation steps and results for landmark recognition, emphatically proposed how to build a nonlinear GA-BP model with genetic algorithm(GA) with nerve network for landmark recognition between Hu moment invariants and landmark to improve the velocity and accuracy of landmark recognition. The GA-BP model is built by the nonlinear mapping ability of BP network and the global optimization of GA. The simulation experiment shows that: the established GA-BP model for the recognition of traffic landmark is better than the BP model without optimization in performance and has good convergence speed and recognition accuracy.Finally, a mobile robot network remote monitoring system was designed and realized in VC platform. The software thought and method are described in detail which are used in the design of network communication,map updating,landmark recognition,motion control and so on. The basic function of mobile robot remote monitoring system based on Internet was implemented by WiRobot mobile robot as research object.
