摘要
将GSM网络的CSD和GPRS2种数据业务结合,应用于远程无线监控系统。提出系统的联网结构,实现基于MC35i无线通信模块的CSD和GPRS硬件接口及软件流程。与传统单一的GPRS方式相比,弥补了数据传输时延大、时延不确定的缺点,既保证了系统数据传输的实时性,又降低了系统的维护费用。现场测试表明,该方法具有很强的实用性和有效性。
This paper proposed a method of combining two types of data service, CSD and GPRS, based on GSM for remote wireless monitor system. Using this method, the network structure of the system was put forward. Then it implemented CSD and GPRS hardware interface and software flow based on MC35i radio communication module. Compared with traditional single mode of GPRS, this method compensated the disadvantage of high delay and uncertainty in data transmission, guaranteed the real-timeness of data transmission and reduced daily maintenance expense. Field test indicated that this method is of high practicability and validity.
