The invention discloses a shared bicycle orderly parking management system based on a mobile phone APP. The system comprises at least two wireless parking piles, a bicycle equipped with an intelligentbicycle lock, the mobile phone APP and a cloud side server. The wireless parking piles set the parking area through the wireless technology, actively scan the bicycle to establish connection and acquire the signal intensity RSSI value to be reported to the cloud side server. The cloud side server performs algorithm analysis on the RSSI value and then makes the parking result to be issued to the mobile phone APP. The mobile phone APP includes a user interface and a background management interface and supports monitoring and use of the bicycle user and the management personnel. The bicycle canonly be parked inside the area, and if the bicycle is locked outside the area, the bicycle lock state information is reported to the server and the cloud side server still regards the bicycle in the use state and continues deduction. Besides, the system has the system self-detection and electric quantity detection function and supports different parking in case of free and busy state of the parking piles so that human input of system operation can be greatly reduced and convenient, rapid and orderly parking can be realized.
