摘　　要：对于远程监控的数据传输问题,提出了基于GSM和CDMA网络的双模无线控制器的方案。采用双网并行的网络策略,解决了单模控制器在网络受到干扰时数据延误的问题,重点阐述了双模结构带来的效率、干扰以及功耗上的问题及其解决方法。同时实现了双模无线控制器的协议设计,开发了相应的程序,并将其应用在机场信息发布系统。实践结果表明,该控制器可以保证远程数据传输的实时性和准确性,性能稳定,能够满足该领域实际需求,具有良好的实用推广价值。To transmit data for remote monitoring, a dual mode wireless controller is presented based on both GSM and CDMA. It solved the data delay problem of single mode controller when network disturbed, in two network paralleling policy. Two mode structure brought efficiency, signal interference and power/energy problems, and solutions of these problems are described. Also, the protocol design is implemented. Based on the controller, a system is developed and applied in a project of airport information publishing system. The results of experiment indicate that it can ensure real-time and accurate data transmission. This technology can satisfy more requirements and its application range is still extended.
