摘　　要：针对传统船舶有线的通信方式需铺设大量的电缆,抗干扰性差、维修难度大,以及舒适度评价系统需要广泛采集全船舱室温湿度的问题,本文选用传输距离远、抗干扰性强的LoRa技术搭建船舶舱室的环境数据无线感知系统。以各舱室为数据采集节点,运用传感器采集相关环境参数,根据舱室类型设置若干独立网关,采用LoRa技术将节点数据无线发送至相应网关,进而利用WiFi将各网关收集的数据发送至上层控制系统,最终在环境舒适度评价模型中进行预计平均热感觉指标的计算与评价。The traditional ship cable communication system needs to lay a large number of cables,which has poor anti-interference and is difficult to maintain,and the comfort evaluation system needs to collect the temperature and humidity of the cabin which is widely distributed throughout the ship.To solve this problem,LoRa technology with long transmission distance and strong antijamming capability is used to build the wireless environment data sensing system of ship cabin.This system takes each cabin as the data acquisition node,uses sensors to collect relevant environmental parameters,and sets up several independent gateways according to the cabin type.LoRa technology is used to send node data wirelessly to the corresponding gateway,and then WiFi is used to send the data collected by each gateway to the upper control system.Finally,the PMV value is calculated and evaluated in the environmental comfort evaluation model.
