Abstract: This paper analyzes the characteristics of acquisition of functions in the technical conditions of the centralized signal monitoring system and verifies the analysis results through on-site trial in specific projects. In this way, it seeks to find installation methods to greatly improve the product quality of the centralized signal monitoring system. Decentralized installation means installation  nearby monitoring objects, this installation method will shorten the monitoring and acquisition wirings and reduce the safety risks. Preinstallation at the factory will advance the field wiring to the assembly and prefabrication stage, which improves accuracy and achieves standardization. The installation method combining these two has been proved to be an effective approach.

Key words: preinstallation, decentralized installation, centralized signal monitoring system, interlocking

摘要： 分析信号集中监测系统技术条件中的各项功能采集特点，通过现场工程试点进行验证，试图找到一种大幅提升信号集中监测系统产品质量的安装方式。分散安装即就近监测对象实施安装，可减少监测采集配线走行径路，降低安全风险；工厂预安装将现场配线提前至组合预制阶段，提高准确率和标准化。二者相结合的安装模式被证明是行之有效的途径。
