驴友安全定位系统
摘要：本设计课题的名称为“驴友安全定位系统”，由于如今人们追求着更健康，更自然，更为个性化的生活方式，因此，传统的旅游已经变得不再满足人们的需求了。越来越多的人，特别是年轻一代，开始尝试户外运动，与旅游相结合的新型户外旅游，如：登山、攀岩、野营、远足、漂流、骑行等活动。但我国的户外旅游发展时间较短，基础设施与国际相比较为落后，且跟不上行业发展的节奏，存在诸多安全隐患。“驴友”遇险不仅会造成自身家庭悲剧，搜救过程也会耗费巨大社会成本。市场急需出现一种新型户外旅游人员安全保障系统，使得“驴友”遇险及时告警、失踪快速找寻，活动组织者可准确了解每位“驴友”的状态，进行有效的安全管理来规避风险。在传统的户外探险中，“驴友”大多数使用对讲机，当遇到地理环境复杂时，无法准确描述当前地理位置，且续航时间较短。本文包含了最初元器件的选型，到系统的搭建，使用了SX1278透传模块，在低功耗的前提下，增加了通讯距离。对于脱离基站的通讯来说，具有极高的实用价值。

Tour pal security positioning system
Abstract：This project is named "Tour pal security positioning system," because now people to pursue a healthier, more natural, more personalized way of life, and therefore, the traditional tourism has become no longer meet people's needs. More and more people, especially young people, began to try outdoor sports, and tourism combination of new outdoor tourism, such as: hiking, rock climbing, camping, hiking, rafting, riding and other activities. However, China's outdoor tourism development time is shorter, compared with the international infrastructure is lagging behind and can not keep up the rhythm of development of the industry, there are many security risks. "ALICE" distress will not only create their own family tragedies, and the search process will be costly social costs. Market need for the emergence of a new outdoor tourism personnel security system, the "ALICE" timely distress alert, quick to find the missing, organizers can accurately understanding each "ALICE" state, effective security management to avoid risks. In the traditional outdoor adventure "ALICE" Most use the intercom, when faced with complex geographical environment, can not accurately describe the current location, and the shorter battery life. This article contains a selection of the original components, to build the system, the use of a SX1278 transparent transmission module, low power premise of increasing the communication distance. For communication from the base station, it has a very high practical value.
Keywords: SX1278; networking no communication station.
