Disclosed are a system and method for efficient nitrogen and carbon removal and phosphorus recovery of source-separated fresh urine by biochemical combination. The system includes a functionally zoned membrane aerated biofilm reactor for in-situ nitrogen and carbon removal, a source separation toilet, a source-separated urine storage tank, a phosphorus recovery reactor, a calcium salt solution tank, a water production tank, and a control system. The membrane aerated biofilm reactor is divided into an upper part and a lower part, a micro-aerobic environment is formed in the upper part while an anaerobic environment is formed in the lower part, and thus nitrogen and carbon can be removed only in the membrane aerated biofilm reactor. The system disclosed by the present disclosure can achieve the goal of removing nitrogen and carbon by 95% and more without additional carbon source, and can meet the demand of in-situ sewage treatment on a train.

The present disclosure relates to systems and methods for determining abnormal information associated with a vehicle. The systems may perform the methods to obtain real-time information associated with a bicycle and obtain reference information associated with the bicycle. The systems may also perform the methods to determine, based on the real-time information and the reference information, abnormal information associated with the bicycle, and transmit the abnormal information associated with the bicycle.

Systems and methods for determining abnormal information associated with a vehicle

A system includes a storage device storing a set of instructions and at least one processor in communication with the storage device. When executing the instructions, the at least one processor is configured to cause the system to obtain a request to close a lock such that the lock is in a locked status, and actuate a control device to cause a locking mechanism of the lock to move toward a first position. The at least one processor may also cause the system to determine whether operation information of the lock satisfies a condition relating to an operation of the lock, and actuate the control device to cause the locking mechanism to move to the first position or a second position based on a result of the determination as to whether the operation information of the lock satisfies the condition.

The present disclosure relates to systems and methods for determining abnormal information associated with a vehicle. The systems may perform the methods to obtain real-time information associated with a bicycle and obtain reference information associated with the bicycle. The systems may also perform the methods to determine, based on the real-time information and the reference information, abnormal information associated with the bicycle, and transmit the abnormal information to a server or a terminal device associated with the bicycle according to a Narrow Band Internet of Things (NB-IoT) technique or a Long Range (LoRa) technique.

A method for vehicle sharing service may include obtaining, from a terminal device, a location of the terminal device via a network. The method may also include obtaining, from the terminal device, information associated with a vehicle, the information including an identifier of a short-range wireless communication module of the vehicle. The short-range wireless communication module may emit a short-range wireless signal. The information associated with the vehicle may further include an intensity of the short-range wireless signal determined by the terminal device. The method may further include determining a location area of the vehicle based on the location of the terminal device and the intensity of the short-range wireless signal.

A method for unlocking a lock may include receiving, via a network, a first service request to unlock a lock from a terminal device. The first service request may be associated with a wireless connection between the lock and the terminal device. The method may also include transmitting, via the network, a password associated with the first service request to the terminal device and receiving an input associated with the terminal device. The method may further include determining whether the received input satisfies an unlocking condition and actuating, based on a result of the determination that the received input satisfies the unlocking condition, a locking mechanism to unlock the lock.

Systems and methods for unlocking a lock

A system may include a storage device that stores a set of instructions and a processor in communication with the storage device. When executing the set of instructions, the processor may be configured to cause the system to obtain, from a user terminal, a first geographical location via a network and obtain a second geographical location associated with a virtual parking region. The first geographical location may be determined by the user terminal according a GPS signal. The virtual parking region may include parking space for vehicles. The processor may also be configured to cause the system to determine whether a distance between the first geographical location and the second geographical location is less than a threshold and obtain information associated with the virtual parking region in response to the determination that the distance is less than the threshold.
