Description
—种粉尘浓度传感器技术领域
[0001] 本实用新型涉及环境參数检测设备，具体涉及ー种粉尘浓度传感器。
背景技术
[0002] 对特殊作业环境下粉尘浓度的实时监测需借助灵敏而有效的粉尘浓度传感器。现有的粉尘浓度传感器普遍存在有体积大携帯不便、检测灵敏度低、性能不稳定和维护不方便的缺点。
发明内容 [0003] 本实用新型的目的在于提供一种体积小方便携帯、灵敏度高性能稳定和维护简单的粉尘浓度传感器。
[0004] 为实现上述技术任务，本实用新型采取如下的技术解决方案：
[0005] ー种粉尘浓度传感器，包括壳体，其特征在于，所述壳体的前面板上设置有液晶显示屏，壳体上设置有进气口和出气ロ，壳体内安装有气体通道和单片机，所述气体通道的一端与进气ロ相通，另一端连接有采样泵，该采样泵与出气ロ相通，所述气体通道的旁侧安装有激光发生器和光电转换器，并且所述的光电转换器与激光发生器相对，所述液晶显示屏和光电转换器均与单片机连接。
[0006] 本实用新型的其他技术特征为：
[0007] 所述单片机采用PIC16F873A单片机。
[0008] 所述壳体上安装有把手。
[0009] 本实用新型的粉尘浓度传感器具有携帯方便、測量快速准确、检测灵敏度高、性能稳定和维护简单的特点。其适用于煤矿及其它有爆炸危险性的作业环境中现场连续监测其大气中的总粉尘浓度，能准确、及时地反映粉尘作业场所中粉尘的污染状況。
附图说明
[0010] 图I为本实用新型的结构示意图。
[0011] 以下结合实施例与附图对本实用新型作进ー步详细说明。
具体实施方式
[0012] 參考图1，按照本实用新型的技术方案，该实施例的粉尘浓度传感器包括壳体1，该壳体I上安装有把手8，壳体I的前面板上设置有液晶显示屏7，壳体I上设置有进气ロ2和出气ロ 6，壳体I内安装有气体通道3和单片机，所述气体通道3的一端与进气ロ 2相通，另一端连接有采样泵5，该采样泵5与出气ロ 6相通，所述气体通道3的旁侧安装有激光发生器和光电转换器4，并且所述的光电转换器4与激光发生器相对，所述液晶显示屏7和光电转换器4均与单片机连接。其中的单片机采用PIC16F873A单片机。
[0013] 仪器在工作时，被检测空气在采样泵5的吸引下通过进气ロ 2定量进入气体通道3，在激光的照射下利用光折射原理对粉尘量进行检测，粉尘量通过光电转换器4被转换为光电信号(该信号与粉尘浓度成一定的比例关系)，该光电信号传输给单片机，单片机对信号进行运算后直接在液晶显示屏上显示出 粉尘浓度和输出测试結果。
Claims (3)
