电力系统火灾不同于其他的火灾,具有破坏性大、火势蔓延块的特点,当前电力系统火灾事故频发,并有逐年上升的趋势。火灾报警系统在保障电力系统安全方面发挥着重要作用,然而现有的火灾报警系统存在采样不准确、数据产生不及时等缺点,造成报警系统不能及时准确地提示火灾的存在。在传统的火灾报警系统的基础上,分析了目前火灾报警系统的缺点和不足,结合电力系统的特殊应用场合,对其进行了系统的优化设计,采用双传感器检测,采用DSP纯数字控制器,引入CAN总线通信方式,实现了较高的系统性能。
Power system fire is different from other fires, with destructive, massive fire spread characteristics of the current power system fire accidents, and there is a trend of rising year by year. Fire alarm system plays an important role in ensuring the safety of power system. However, the existing fire alarm system has some shortcomings such as inaccurate sampling and inaccurate data generation. As a result, the alarm system can not promptly prompt the existence of fire. Based on the traditional fire alarm system, the shortcomings and shortcomings of the current fire alarm system are analyzed. Based on the special application of the power system, the system is optimally designed. The dual-sensor detection, DSP pure digital controller, The introduction of CAN bus communication, to achieve a higher system performance.
