Detailed Description

Reports indicate that the public bicycle market in china has undergone three stages of development. The first stage is 2007-2010, public single cars are introduced into China from a public single car mode established abroad, and the government leads to city management, and most single cars are piled. In the second phase, 2010-2014, enterprises dedicated to the single-vehicle market begin to appear, but public single vehicles still mainly have piled single vehicles. As the third stage in 2014, with the rapid development of the mobile internet, public bicycles such as OFO come on line, and more convenient and faster non-pile bicycles are beginning to replace single-pile bicycles.
The report shows that at present, OFO and Mobai two enterprises in the China public bicycle market have obvious advantages, wherein the most put-in amount of OFO single bicycles reaches 80 thousands of bicycles, and the market share is 51.2%; 60 million Mobai single cars with the market share of 40.1 percent.
The report also shows that public bikes are more popular with young men. In China public bicycle users, male accounts for 54.2% and female accounts for 45.8%. In the age distribution of users, people between 25 and 35 years are used most, and people under 25 years are used secondly. Of the frequency of use, the users who are used 3 to 4 times a week are the most.

In addition, frequency division duplex means that uplink and downlink transmissions are performed on different frequencies. In the frequency division duplex mode, the uplink and downlink transmissions are made on different frequencies, respectively. The principle of which is shown in the following figure. f1 and f2 are the transmission frequency and the reception frequency, respectively, of a certain mobile station that is performing traffic transmission.
In the first and second generation cellular systems, FDD technology is basically used for duplex transmission. In particular, in the first generation cellular systems, since continuous baseband signals are transmitted, duplex uplink and downlink channels must be provided using different frequencies. In the first generation cellular systems, in which FDD is used for continuous information transmission, frequency synthesizers for generating different carrier frequencies are required at both the transmitting and receiving ends, and a duplex filter for preventing the transmission signal from leaking to the receiver is required at the receiving end. In addition, in order to facilitate the fabrication of the duplexer, a certain frequency interval is required between the transmission and reception carrier frequencies. In the second generation of systems such as GSM, IS-136 and IS-95, FDD technology IS also used. In these systems, since the information is transmitted in time slots, the transmission and reception can be performed in different time slots, and the transmission signal of the mobile station or the base station does not interfere with the receiver. So, despite the FDD technique employed, no expensive duplex filters are required.
The FDD mode is characterized by receiving and transmitting in two symmetric frequency channels separated (190 MHz between uplink and downlink frequencies), and separating the receiving and transmitting channels by guard bands.
By adopting the technologies of packet switching and the like, the bottleneck of the second generation development can be broken through, the high-speed data service can be realized, the frequency spectrum utilization rate can be improved, and the system capacity can be increased. FDD must provide third generation services using paired frequencies, i.e., within a bandwidth of every 2x5 MHz. The mode can fully utilize the uplink and downlink frequency spectrums when supporting the symmetric service, but the frequency spectrum utilization rate is greatly reduced (about 40 percent of the frequency spectrum utilization rate is reduced due to low uplink load) when the asymmetric packet switching (Internet) works, and in this regard, the TDD mode has incomparable advantages compared with the FDD mode.
By adopting the shared bicycle toppling state detection system, aiming at the technical problem that the shared bicycle in a toppling state is difficult to find and maintain quickly in the prior art, the primary toppling state is judged through analysis of navigation data receiving intensity, if the non-toppling state is judged, the final judgment is carried out without starting complex and more real remote sensing image detection, and more importantly, the remote sensing image is subjected to self-adaptive step-by-step filtering processing based on image content, so that the accuracy of the detection result is further ensured.
