Mobile type high-power alternating current (AC)/direct current (DC) hybrid power supply device

ActiveCN103427608AOvercomes the fundamental drawback of having to tie into an active networkDoes not increase short circuit capacityPower conversion systemsControl systemAlternating current
The invention discloses a mobile type high-power alternating current (AC) / direct current (DC) hybrid power supply device which comprises a vehicle-mounted platform, a control system and more than two even converter groups. Each of the converter groups comprises more than two converter units which are connected in a mode of parallel connection of input sides and serial connection of output sides, and sequentially, AC / DC output is achieved by a serial connection or parallel connection manner of the converter groups. The control system is connected with the converter units of the converter groups and achieves controlling and monitoring of the converter units. The control system and the more than two even converter groups are installed on the vehicle-mounted platform to achieve mobile type AC / DC power supply. According to the mobile type high-power AC / DC hybrid power supply device, the relationship of serial connection and parallel connection of the converter groups is flexibly converted to achieve output of AC / DC voltage of the hybrid power supply device; and the converter groups and the control system are flexibly dragged by an automobile, so that the device is applicable to various kinds of resistance-inductance loads, achieves bi-directional flow control of energy, and can be widely applied to various kinds of load targets.

Driver and passenger communication method and system based on personal privacy secrecy

The invention relates to the technical field of communication, in particular to a driver and passenger communication method and system based on personal privacy secrecy. The method comprises the stepsof receiving a communication request after an order is formed, starting recommendation work, and evaluating signal intensity of two parties by the recommendation work; if both the passenger and the driver are in the strong signal state, enabling the recommendation work to recommend a telephone call to the initiator of the communication request; if both the passenger and the driver are in a strongnetwork state and any party is in a weak signal state, enabling the recommendation work to recommend a voice call to an initiator of the communication request; and if any one of the passenger and thedriver is a weak signal and any one of the passenger and the driver is in a weak network state, enabling the recommendation work to recommend a message call to an initiator of the communication request, and when any one initiates a request of ending the communication, terminating the communication. The communication method and system have the advantages of diversified selection, good adaptabilityand privacy protection, solve the problems that an existing communication method is single in selection, large in limitation and poor in privacy protection effect, and meet the communication requirements of users.
