Currently in a surface warship of the our country everyplace all provided with the sail coal gas body to report to the police the instrument on the boat, gas density that sensor adopt to convey gas density value traditional 4-20mA mode of analog signal, have to each measure passway allocate one is it is it report to the police to measure to have and density value show measuring board of function, as the density of gas measures the passway board of the different quantities of different outfit of the figure of the passway, but there is many figure of the large-scale naval vessel passway, so the volume of warning system will become very huge , unfavorable to attenbants to use, and traditional 4-20mA electric current ring transmits the signal, unfavorable to transmitting at a long distance, easy to bring and interfere.

核心提示：摘要目前在我国各地型水面舰船上都配备了航煤气体报警仪，气体浓度传感器采用的是传统的4-20mA模拟信号的模式传送气体浓度值，只好每个检测通道配备一块具有检测报警及浓度值显示功能的检测板，随着气体浓度检测通道数目的不同配备不同数量的通道板，但大型舰船通道的数目比较多，因此报警系统体积会变得十分庞大，不利于操作人员使用，而且传统的4-20mA电流环传输信号，不利于长距离传输，容易带来干扰。为了巡检的需要，需要将其改造成现场智能仪表，通过将传感器检测结果

Microcontroller through the infrared sensor part and the voice-activated sensor part of the coming changes in the signal to determine whether there are outsiders, if sent through the speakers or the diode to the police; infrared sensors, infrared emission through the launch tube to the receiving tube, two between elements of a connecting via infrared, when there are objects stand in the middle, they then pass on the changes in level microcontroller; Similarly, voice-activated sensor is converted into electrical signals into acoustic signals and then transmitted to the microcontroller; keyboard is used to set the alarm trigger conditions.

单片机通过红外传感部分和声控传感部分的传来的信号的变化来判断是否有外来者，如有则通过扬声器或者发给二极管来报警；红外传感器是通过发射管发射红外线到接收管，两个元件之间通过红外线进行连接，当有物体挡在中间时，便把电平的变化传给单片机；同理，声控传感器是把声音信号转换为电信号然后传送给单片机；键盘是用来设置报警触发的条件。

In this regard, some experts that the sensor only to meet certain conditions it will work, the design of airbag sensors there are many, some are lever-type switch or pendulum, as well as the spring load of wheel type, There are also products that use mercury switches.
