2.1 Orienteering
Orienteering can be traced back to the 18th century. It has a history of 100 years. At that time, orienteering mainly focused on outdoor activities. By the 1930s, orienteering had been established in Finland, Norway, Sweden, Denmark and other cities. In 1961, the International Federation of mentoring organizations was established in Copenhagen, with 63 member states. The actual competition was held in Stockholm, Sweden, and Oslo, Norway, in 1895, marking Orienteering as a sporting event. Early orienteering is mainly a means that people are forced to take for survival. With the improvement of people's living conditions, orienteering has really become a leisure sport in modern life. As a new sport, orienteering refers to athletes using North needle and map to find the location of each point on the drawing, and reach all points in the shortest time to win the game. Orienteering is not only an entertainment activity, but also a competitive sport. In addition to carrying maps and directions, orienteering does not need any special equipment, and there are no restrictions on participants. Compared with other sports, this is a relatively economic sport, and it is suitable for different people of different ages [4-6].
2.2 Development Form and Characteristics of Orienteering
Nowadays, there are various forms of orienteering, but the most basic ones are walking orienteering, relay orienteering, skiing orienteering, night orienteering, 100m orienteering, special route orienteering, five-day Orienteering [7-9]. At present, orienteering has the following four characteristics:
(1) Universality of participants
The purpose of sports is to let the whole people participate, share health and happiness, and choose a meaningful and valuable sport to meet the requirements of sports. Orienteering can be held at different levels according to the gender and age of each athlete. Because the duration of Orienteering can be long or short, orienteering is a mass sport with comprehensive physical strength and intelligence, suitable for men, women, old and young. Generally speaking, as long as a certain physical quality can participate, the difficulty can also be adjusted at any time according to the participants.
(2) Entertaining and social
In orienteering, athletes search each checkpoint in the order of points on the map. In this process, each athlete can choose his own route or cross the terrain, which is more interesting and initiative than running. In addition, orienteering competitions are often arranged in parks, wild areas and forests, so athletes can not only enjoy the charm of orienteering, but also enjoy the natural scenery. At the end of the competition, athletes exchange experience in the direction and route selection of the whole competition, further reducing the friendly relationship between athletes. At present, this kind of sports mode is also widely used in team building and friendship competition, which is a good communication sport. Especially in international competitions, international sports exchanges have been strengthened and personal international friendship has been established.
(3) Fierce competition
The charm of sports competition is to win in the competition field through the competition among athletes. The competition characteristics reflected in the competition process are basically all sports. However, orienteering depends not only on physical strength, but also on intelligence and skills. The speed and endurance of running depend on the strength of the body, and the right direction and route selection depend on the ability to see a map and use a pointing needle. Therefore, orienteering not only tests a person's physical quality, but also exercises his psychological and comprehensive judgment ability. Especially the people who play the leading role in the team often need higher comprehensive quality to lead the team to win.
(4) Popularization of knowledge
Orienteering is of great significance to improve people's ability to read and use pictures and enhance their international competitiveness. Li KaShing once said: knowledge changes fate, struggle can achieve the future, young people must strengthen the cultivation of knowledge ability in their learning career. Teenagers' Orienteering can not only adjust their learning mood, strengthen their physique, enrich their geographical knowledge, but also cultivate their self-survival ability in outdoor activities or strange cities. It has certain military significance for the military police, police and rescue personnel to carry out this campaign and help them to complete the tasks of marching, fighting, reconnaissance and search and rescue. It can be said that orienteering is a very practical sport, which is more comprehensive for the test of participants, rather than a single force, or speed, which is more beneficial for young people, especially for their character growth.
2.3 Overview of the Internet of Things
In 2009, the Chinese government proposed the "PERCEPTION of China" plan, vigorously supported the development of the Internet of things industry, and promoted the development of the Internet of things industry chain as a new industry to the strategic position of China's development. On August 7, 2009, Wen visited the Internet of things technology research and development center of the Chinese Academy of Sciences in Wuxi. He especially pointed out that the core technology should be broken as soon as possible, and the sensor technology should be combined with China's 3G technologies. At the 2010 NPC and CPPCC sessions, Premier Wen Jiabao proposed to "accelerate the development and application of the Internet of things" in the work report of the government. Due to the attention of the government, the Internet of things began to enter the public life gradually. Internet of things is a network based on computer technology, which connects all things through RFID tag technology, wireless data communication and other technologies. Its essence is to realize the automatic identification of goods (commodities) and the Internet sharing of information through the Internet of things by using radio frequency identification technology. The timely sharing of information is one of the core technologies of the Internet of things [10-12].
2.4 Overview of Location Services of the Internet of Things
Location service of the Internet of things is one of many applications of the Internet of things. Location service plays an important role in many applications of the Internet of things. From personnel tracking, emergency services to asset management, driving navigation, it can almost cover all aspects of the Internet of things applications. Location service, also known as location service, is a kind of value-added service related to location information, which combines mobile communication network with various location technologies. The location information of Internet of things terminals (such as altitude, longitude, latitude, etc.) is obtained through certain positioning technology, and transmitted to location service users or management system, so as to realize various services based on location information. At present, the Internet of things positioning service has been applied to various scenarios, including asset management, personal positioning, tracking query, etc. the service can identify the location information of a person or asset, such as determining the current location of a specific person or asset, or querying the current vehicle location information and its track in a specific time. In addition, businesses can also push targeted information through different locations of current users, including personalized weather information, local consumption information, appointment information, etc. In short, with the rapid development of the Internet of things industry, the rapid growth of the global smartphone market and the growing maturity of the mobile Internet market, the demand for location-based services has exploded [13-15].
