The invention discloses a fog computing based road information service system and method during city traffic congestion. The system comprises a vehicle-mounted intelligent terminal, a fog server, a roadside unit and a roadside cloud server module. The method comprises the following steps: 1, constructing a local area network; 2, positioning a vehicle; 3, sending a service request; 4, receiving the service request; 5, planning a driving route; and 6, feeding back an optimal path. According to the invention, the local area network is constructed by use of the fog server, real-time road condition information under jurisdiction is collected and is transmitted to the roadside unit governing the fog server, the roadside unit plans the driving route according to destination address information of the vehicle and the real-time road condition information, and the system and method are enabled to have the advantages of low delay, position perception, wider geographical distribution, suitability to more nodes and less driving time.

The invention discloses a remote data transmission system and method for a gas turbine sensor, belongs to the technical field of monitoring of gas turbine sensors, and solves the problem that at present, remote data transmission of the gas turbine sensor demands much on data transmission bandwidth and load capacity of a server. The transmission system comprises a plurality of sub-clients, a server-side communication server, a decompression server and a server-side database; and each sub-client comprises a plurality of sensors, a client database, a client data sampling server, a compression server and a client communication server. According to the invention, as the load balancing method is adopted, the system has stronger load capacity; and as the compression algorithm with linear time complexity is adopted, the data can be efficiently compressed before being transmitted to the server-side from the client, and accordingly the requirement on data transmission bandwidth is lower. The system and the method, provided by the invention, are suitable for remote data transmission of the gas turbine sensor.

The invention relates to a direct-drive ground generating set for high-altitude power generation, and belongs to the technical field of high-altitude wind power generation. The ground generating set comprises a generator and brakes, rollers, clutches and motors which are arranged on two sides of the generator symmetrically, wherein two ends of one roller and two ends of the other roller are connected with the brakes; two ends of a rotor shaft of the generator are connected with the brakes at one end of one roller and at one end of the other roller; the brakes at the other ends of the rollers are connected with the motors through the clutches; when the generator generates electricity, the two rollers are connected with an aerial work doing umbrella through ropes; and the two clutches are connected with an external control part and controlled to alternately work, so that the generator generates the electricity continuously, and the generated energy of the generator is improved. The ground generating set can transmit aerial mechanical energy to the ground; and the two clutches are controlled to alternately work by the external control part, so that the generator is in a working stateall the time.

The invention relates to a treatment method of cement kiln incineration polluted soil. The method aims to implement stabilization, reduction, harmless treatment and recovery of polluted soil. The scheme is as follows: the method comprises the following steps: A. polluted soil is transported into the factory and subjected to platform balance metering, and enters a polluted soil crusher anti-blocking discharge bin; B. the polluted soil enters a multistage impact crusher and is subjected to crushing treatment; C. the polluted soil is sent into a finished product stocking shed by a stocker and subjected to stocking and homogenized storage; D. the material is transported and poured by a special polluted soil truck into an anti-blocking discharge hopper; E. the material is directly conveyed by a metering conveyor into a cone below a dripping box in a kiln tail decomposition furnace; F. high-temperature gas of the kiln tail decomposition furnace is used for evaporating moisture in the polluted soil, the polluted soil is incinerated, the incineration ash enters a rotary kiln, and the waste slag is directly used as a cement raw material; and G. hot fume after polluted soil incineration enters a kiln tail system and performs heat exchange with an in-kiln crude material, and meanwhile, part of harmful substances are decomposed. The method is suitable for treating polluted soil.
