摘要
针对天津市屈家店水利枢纽工程的实际情况和水位、电量综合测量系统的具体需求,利用浮子式水位传感器和智能仪表实现对现地数据的采集,同时,将现地各LCU单元通过光纤和交换机搭建以太环网,实现对数据的远程监测。重点介绍了针对变电所智能仪表的MODBUS数据采集过程,通过对TSX SCP114通信卡的通信机理、接线方式的深入研究、通信参数的合理设置及通信函数的正确选用,大大提高了系统的通信性能。
For the need of the Qujiadian hydraulic project and the requirement of the complex measuring system,all the LCU constructed the Ethernet ring network,by which,the field data gathering from the water level sensor and the intelligent instrument can be collected and monitored remotely. The MODBUS data acquisition process of intelligent instrument for substation is introduced. With the help of the studying for the communication mechanism and connection mode of the TSX SCP 114 card,the Reasonable setting of communication parameters and the correct selection of communication function,the performance of the system can be greatly improved.
