Through mobile Internet possessing central node, mobile terminal accesses metamessage file of P2P service and obtains related information of data file. When carrying out data transmission, the method carries out shared data transmission through blue teeth to infrared etc wireless peer-to-peer network not possessing central node directly. Through central server to transfer control signal, the invention changes unordered wireless peer-to-peer network to controllable peer-to-peer network. Then, based on store and forward principle, the invention realizes data transmission between terminal devices not connected to each other directly so as to raise capability of sharing data between terminal devices in wireless peer-to-peer network.

The invention discloses a parking stall subscription system with a parking stall management function of a parking lot. The system comprises a user subscription terminal, a parking stall managing server, a network server, parking stall detectors and parking stall subscription devices, wherein repeaters are arranged between the parking stall managing server and the parking stall detectors, the parking stall managing server is equipped with an ergodic module, a relay starting module and a parking stall information collecting module, the ergodic module is communicated with the parking stall detectors to detect whether links between the parking stall detectors and the parking stall managing server are normal, the relay starting module is used for starting the repeaters and enabling the repeaters to be in polling states, and the parking stall information collecting module is communicated with the parking stall detectors and collects state information of parking stalls. The system can display parking stall information in real time, guide a parker to reach the corresponding parking stall, and achieve the goal of advanced subscription for a vacant parking stall.

The invention discloses a system for guiding nearby objects in a parking lot. The system is characterized by comprising parking space detectors, parking space displayers and parking space guiding screens. The parking space detectors are arranged on all parking spaces of the parking lot and used for monitoring the states of the corresponding parking spaces inside the parking lot and sending the state information of the corresponding parking spaces and the address information of the parking space detectors to the parking space guiding screens. The parking space displayers are arranged on all parking spaces of the parking lot and used for displaying the parking space information, the nearby object information related to the geographical positions of the parking space displayers and guiding information for guiding a user to one nearby object. The parking space guiding screens are used for regularly polling the state information of the parking space detectors connected with the parking space guiding screens, storing the state information newly sent by the parking space detectors and displaying the parking space information to guide the user to the corresponding parking space. The parking space guiding screens are further used for projecting the information of the nearby objects of the parking space guiding screens to the parking space guiding screens. The purpose of guiding the user who wants to park to enter a vacant parking space can be achieved, and the purpose of finding the objects conveniently can be achieved.

The application discloses a monitoring method, device and system for an energy storage system, which can determine the current operating state of the energy storage system; The target data item to be monitored, the data item to be monitored is part or all of the data items in the operation data of the energy storage system; a data monitoring request is sent to the monitoring module for requesting the monitoring module to collect the target data to be monitored data of the item; receiving the data of the target data item to be monitored collected by the monitoring module. Because the monitoring module does not collect all data items in the energy storage system operating data at all times, but only collects target data items to be monitored that match the current operating state of the energy storage system. Therefore, the amount of data collected by the monitoring module can be reduced, thereby reducing the amount of communication data between the energy storage system and the upper controller, and saving transmission resources.
