A cell-based vehicle driving control system includes a local server for obtaining road environment information on roads within a cell and target vehicle information on a target vehicle within the cell and generating local waypoints based on the road environment information and the target vehicle information; a global server for monitoring the target vehicle information, the road environment information and local server information on the local server received from the local server; and a vehicle control terminal, mounted in the target vehicle, for receiving the local waypoints from the local server and controlling the target vehicle based on the local waypoints. The road environment information is obtained by using at least one sensor installed on the roads.

The invention discloses a local side transceiving device based on OCDMA two-dimensional electro-optical coding and decoding, and a coding / decoding method thereof. The device is mainly composed of an electric time domain delay coding and decoding module, an optical frequency domain coding and decoding module, an optical coupler, a system management module and a power supply management module. The electric time domain delay coding and decoding module is connected with the optical frequency domain coding and decoding module. The electric time domain delay coding and decoding module carries out time domain delay coding on n user data electric signals issued by a core network according to a unique optical address code distributed to each user, couples the signals after time domain coding, and then sends the n user coupled electric signals to the optical frequency domain coding and decoding module for synchronous frequency domain coding according to the optical address codes. The optical frequency domain coding and decoding module converts the electric signals sent by the electric time domain delay coding and decoding module into optical signals, carries out optical frequency domain coding, and sends the optical signals after two-dimensional t-lambda coding to an optical distribution network for distribution directly or through the optical coupler. The device is characterized by simplicity, feasibility, high reconstruction, large capacity and fast speed.

The invention discloses a self-synchronizing method of point-to-point communication of UAV data chaining under time slot allocation system, which is based on MCS-51 serial singlechips, wherein, the method comprising fives steps of: initializing data chaining communication system, synchronously initializing, synchronously locking, self-adaptedly emitting TSA as well as desynchronizing and resynchronizing. The invention adopts the time slot allocation system to carry out data chaining communication, wherein, an onboard control station and a ground control station adopt the same communication device to complete the sending and the receiving of information under the same working frequency and different time points; adopts point-to-point communication based on equivalent theory, in the synchronously building process, the communication system of the onboard control station and the ground control station has equivalent position without difference between the main and the subsidiary; adopts the self-synchronizing method based on a synchronous head, which is superior to a external-synchronizing method taking GPS second pulse signal as assist on reliability and synchronizing time; and adopts self-adaptedly allocation strategy which emmits time slot based on the the amount of information content in data buffer, thereby, being caplbe of effectively reducing onboad energy consumption.

The invention discloses a fault diagnosis method for a secondary system of an intelligent substation. First, a fault information database is generated based on the fault information of the secondary system and the characteristics of the fault information corresponding to the fault information; The system data of the secondary system is identified to obtain the identification results of fault information, and the system error data and fault information characteristics are obtained; and then according to the fault information database, the fault information identification results are analyzed to obtain the type of system fault and the location of the system fault. Compared with the existing technology, there is no need to increase the complexity of the equipment, only need to analyze and diagnose according to the fault information detected by the secondary system, and the system fault type and system fault location can be obtained, which greatly reduces the fault diagnosis of the secondary system of the substation. The equipment complexity and design complexity have improved the system fault diagnosis ability of the original substation secondary system. The invention also discloses a fault diagnosis device and equipment for the secondary system of the intelligent substation, which have the above beneficial effects.
