摘要
针对煤矿气体传感器采用遥控器人工校正方式可能导致有毒气体威胁调校人员生命安全等问题,提出一种红外信号发送模块设计方案,详细介绍了红外调校原理、红外信号传输协议的获取、红外信号发送模块的软硬件设计及其在传感器调校中的应用。将该模块集成到校验仪器上,可实现传感器的自动闭环校验,同时可在上位机系统数据库中集成多种红外信号传输协议,使得用户在使用时仅需选择对应传感器类型即可完成传感器技术参数的设定,从而大大提高工作效率。
In allusion to problems that coal mine gas sensor uses manual calibration may lead to toxic gas threat to personnel life, the paper proposed a design scheme of transmit module of infrared signal, and introduced infrared adjustment principle, obtain of transmission protocol for infrared signal, hardware and software designs of the module and its application in sensor calibration. Integrating the module to calibration equipment can achieve automatic closed-loop calibration of sensor, while a wide range of infrared signal transmission protocols can be integrated in database of host computer system, which enables users to complete setting of technical parameters of sensors by simply selecting the corresponding type of sensor, so as to improve work efficiency.
