【摘要】：目前大多数火灾烟雾报警器都是由火灾烟雾传感器和火灾烟雾探测芯片组成,烟雾探测芯片通过对接收到的传感器信号进行处理分析,从而判定是否有火灾发生,这种方法虽然结构简单但反应慢,存在误报和漏报等问题。为此提出一种单片机的火灾烟雾报警器设计方法。首先,设计监测CO浓度、烟雾浓度以及温度变化的传感器,用A/D转换电路将传感器检测信息转换成单片机可处理的数字信号,通过ZigBee无线通信技术将单片机处理过的信号传输到火灾烟雾报警器控制服务器模块,完成博物馆内火灾烟雾报警器硬件设计。利用连续概率模型对采集获得的温度、烟雾和CO浓度信息进行分析处理,由此完成博物馆内火灾烟雾报警器设计,提高火灾报警的准确性和及时性。通过仿真实验证明,所提方法能够有效提高报警器报警的准确性和及时性,能够快速地反应整个火灾概率过程,并给出预警、报警信号,符合博物馆的使用条件,具有良好的使用价值。
[Abstract]:At present, most fire smoke alarms are made up of fire smoke sensors and fire smoke detection chips. The smoke detection chips process and analyze the received sensor signals to determine whether there is a fire or not. Although the structure of this method is simple, the reaction is slow, and there are some problems such as false positives and omissions. In this paper, a design method of fire smoke alarm based on single chip microcomputer is presented. First of all, a sensor is designed to monitor the change of CO concentration, smoke concentration and temperature. The detection information of the sensor is converted into a digital signal which can be processed by a single chip microcomputer. The signal processed by single chip computer is transmitted to the control server module of fire smoke alarm by ZigBee wireless communication technology, and the hardware design of fire smoke alarm in museum is completed. The continuous probability model is used to analyze and process the collected information of temperature, smoke and CO concentration, thus the design of fire smoke alarm in museum is completed, and the accuracy and timeliness of fire alarm are improved. The simulation results show that the proposed method can effectively improve the accuracy and timeliness of alarm, can quickly reflect the whole process of fire probability, and gives the warning signal and alarm signal, which conforms to the conditions of use in the museum. It has good use value.
