【摘要】 为了满足远程监控水源井的要求,选用RTU来实现远程监控.设计了RTU的基本硬件电路,采用MAX706芯片组成的电路作为系统的复位电路,利用无线通讯组网方式实现远程监控和数据传输,并设计了防止电台长发射电路.结果表明,采用无线电台组成的网络可以很好地实现水源井的远程监控.同时,设计的防止电台长发射电路解决了以往存在的电台长发射问题,RTU在保证运行的稳定性基础上,降低了成本,但对该系统功能的拓扑仍需进一步探讨.更多还原

【Abstract】 In order to meet the requirement of remote monitoring watersource well,Remote Terminal Unit was adopted.The basic hardware circuit was designed according to the properties of the system,the reset circuit was planned on the basis of MAX706,the remote monitoring and data transmission were realized by the mean of wireless communication networking,while a kind of circuit was used for preventing the radio from being launched all the time.The results show that the network,made of wireless radio,can fulfil the task of remote monitoring.Conclusion can be made as follows:The circuit,used for preventing the radio from being launched all the time,has resolved the present problem;The cost of Remote Terminal Unit was cut down on the foundation of the stability;how to expand other Functions of system is still a arduous task.更多还原
