[Abstract]:With the rapid development of computer control technology and the maturation of network technology, the application field of control system is more and more extensive, and the control object is becoming more and more complex.The control system is developing towards the direction of digitization, network and intelligence.Logarithmic periodic antenna as a shortwave communication antenna has been widely used in special situations such as communication and disaster relief. The networked control of rotatable logarithmic periodic antenna is based on the maturity of networked control technology and the practical requirements of users.In order to meet the requirement of networked control of rotating antenna, this paper designs a network control scheme based on B / S architecture using computer network, communication, database and other technologies.The system is composed of Web server, communication server, network control unit, antenna driving unit and antenna. The Web server provides network antenna control service for IE users.The communication server is the communication hub connecting the Web server and the device, and the antenna driving unit mainly completes the antenna drive control.In order to meet the requirements of the development of the communication core equipment, the network control unit (NCU), the design of the overall scheme of NCU, the core CPU board, the optical communication board, the relay board and the power supply board is completed by using advanced embedded technology and bus communication technology.This paper introduces the principle and design idea of the main hardware circuit in detail.Based on the embedded operating system 渭 C / OS-IIand using the key technologies such as task, queue, state machine / TCP / IP network communication, the control software of NCU is developed. The functions of fixed point, positioning, point movement, calibration and parameter setting of rotating antenna are realized.The general design framework of the controller, the detailed flow of the program and the state machine of keyboard management are given in this paper.On this basis, the system testing platform is built, the NCU device level function test and the system cascade adjustment test are carried out. The results show that the networked control system architecture is reasonable, the network control unit developed is reliable in communication and stable in operation.Be able to take on its function and performance requirements as a communication hub.The system and related equipment developed at present have been delivered to the users for use.
