| In order to realize the compatibility and interoperability of different manufacturers, the standard AISG protocol is developed by Antenna Interface Standards Group for the antenna interface system and the related products. In foreign related products most strictly follow the AISG protocol. China has basically achieved the transition to AISG protocol specification but now the remote control of the electric antenna device is through control system such as a handheld remote controller close control, and is not in the true sense of the remote control. In addition, the control of antenna equipment has a problem that the scanning efficiency is low and the scanning time is long. In view of the above two problems, based on the research of the AISG protocol, this thesis implements the control system of remote electrically tunable antenna device based on AISG protocol. The specific work of this thesis is as follows:First, this thesis completes the research and implementation of AISG protocol. This thesis studies the theory of AISG protocol, analyzes the principle of the AISG protocol stack, and puts forward the solution to realize the AISG protocol stack, and implements the three layer protocol model of AISG protocol. The experimental results show that the proposed protocol stack has strong stability and reliability, and it can ensure the reliable communication and stable communication.Second, this thesis completes the hardware design of the control system of the remote electrically tunable antenna equipment. In this thesis, the hardware requirements of the remote control system are analyzed, and the corresponding hardware modules are designed, and the basic platform of the hardware needed for the remote control system is realized. The experimental results show that this platform not only has a good stability, but also has a stable reliability, thus ensuring the software to achieve the required hardware environment.Third, according to the control for electrically adjustable antenna device is not remote control, this thesis realizes the adjustable antenna equipment remote control protocol and AISG protocol conversion gateway power. This thesis analyzes the principle of remote control electric tuning antenna device, proposes the solution of remote control electric tuning antenna device, realizes the unique system of embedded Web server. The experimental results show that the solution to achieve a good antenna equipment of electric remote control, which has high efficiency.Fourth, according to the low efficiency problem of antenna scanning equipment, this thesis completes the research of scan algorithm of electrically adjustable antenna device. Based on the research in current scanning algorithm of electrically adjustable antenna device, this thesis presents two core scanning algorithm based on the AISG protocol, namely general electric tuning antenna device scanning algorithm and special electric antenna device scanning algorithm, and realizes the application of two scan algorithm in the system. The experimental results show that the proposed antenna device scanning algorithm can obviously improve the scanning efficiency, improve the accuracy and real-time of system for scanning equipment.Finally, this thesis completes the design and implementation of the overall control system. In this thesis, the overall function of the system is introduced, and the function of the specific module of the remote control system is realized. Experimental results show that the remote adjustable antenna device control system based on AISG protocol can better solve the problem of the electrically adjustable antenna device remote control and electrically adjustable antenna scanning equipment efficiency low, which has a high reference value to the antenna industry. |
