火车站给水系统中OMRON CP1H与研华模块的无线通讯:通常在许多控制系统中,有部分被控设备需要遥测遥控.但往往不便于铺设电缆和光纤(如：山坡、河流、城市建筑等挡住铺设电缆的路径)，此时，PLC控制系统通过无线遥测遥控就显得尤为重要。该系统硬件主要由一块OMRON CP1H-XA40DT-D型PLC、两块捷麦无线数传模块、一块研华ADAM4050亚当模块及一块研华ADAM4017亚当模块组成。采用OMRON电气公司开发的与PLC相配套的CX—Programmer7.1编程软件来编写研华模块的指令程序和水塔、清水池的控制程序。用捷麦的测试软件对无线数传模块进行参数设置。采用美国wonderware公司的InTouch组态软件编制整个工艺流程的设备状态，达到的参数实时监控。该系统有友好的人机控制界面，简单、实用、方便、可靠、性价比高。该系统通过了验收鉴定，各项控制指标达到了预定要求，已在铁路系统中得到了广泛应用。Abstract:Among many control systems, there are partial equipment controlled shall require remote measurement and remote control usually, but which is inconvenient to lay the cable or optical fiber (such as wiring route is blocked by hillslope, river or city building). So it appears more important to execute wireless remote measurement and remote control by PLC at this time. The system mainly is composed by an OMRON CP1H-XA40DT-D PLC, two JAMMY wireless data transmission modules, an ADVANTECH ADAM4050 and an ADVANTECH ADAM4017. CX—Programmer7.1 matched with PLC and developed by OMRON Electric Company is adopted to compile the command procedure and control procedure of water tower and filter water basin for ADVANTECH module,JAMMY testing software is adopted to set parameters for wireless data transmission module as well as InTouch configuration software of America Wonderware Company is used to compile the equipment status of whole process flow, so as to real time monitor the parameters and human-computer control interface. The system is simple, practical, convenient and reliable, with high performance ratio, and has passed acceptance certification, its different control indexes have reached the desired requirements. The system is widely applied in railway system.
