摘要
LoRa物联网无线传输技术具有绕射能力强、功耗低、链路预算高的特点,特别适合于油田数字化油气水井生产和工况数据传输中的低速率、远距离、地形地貌复杂的应用场景。当前LoRa WAN协议开发还不成熟,仅支持透明传输,无法大规模组网应用,但可以作为局部区域的无线接入或无线骨干网的覆盖延伸技术,具有较高的推广应用价值。基于数字化油田对多媒体宽带传输的需求,油气水井场可采用TD-LTE作为主要覆盖网络,部署TD-LTE LoRa网关,用LoRa技术实现复杂地貌环境下井场无线传感器数据的中继接力传输。
LoRa wireless transmission technology for Internet of Things has characteristics of strong diffraction capability, low power consumption, and high link budget, and it is especially suitable for the application scenarios with low rate,long distance and complicated terrain in digital oil,gas and wa-ter well production and data transmission of working conditions in oilfields. The current LoRaWAN protocol development is not mature,it only supports transparent transmission and cannot apply in large-scale networking. However, it can be used as the overlay extension technology for wireless access or wireless backbone network in local areas,having high application value.Based on the demand of digi-tal oilfield for multimedia broadband transmission,well sites for oil,gas and water wells can apply TD-LTE as the primary overlay network and lay out TD-LTE LoRa gateway, using LoRa technology to realize the data relay transmission for the well site wireless sensor in a complex geomorphic environment.
