Description
Technical Field
The invention relates to a data transmission technology of a city brain system, in particular to a management data transmission method for transmitting management data between a data storage server for performing wireless communication and a plurality of user terminals in the city brain system.
Background
In the urban brain system, it is necessary for each user terminal to efficiently transmit urban management data to data storage service sessions distributed in each area in real time. Here, the city management data includes various surveillance videos, government publicity videos, tables, text files, city management collection data, and the like, and each day includes a large amount of data.
Generally, the environment and the position for setting the data storage device are preset and cannot be moved after being set; the number of the user terminals is huge, and the user terminals move at any time, and the environment of the user terminals cannot be predicted and limited. Moreover, the communication between the data server and each user terminal is performed by using a mobile communication network, and the communication between the user terminals can be performed by a direct communication mode among the mobile terminals such as a local area network, WIFI, bluetooth and the like in addition to the communication through the mobile communication network.
Since one data storage server needs to respond to a plurality of user terminals, the data storage server dynamically allocates communication channel resources to each user terminal that requires transmission of management data, and requires different encoding schemes and data transmission times for each user terminal according to the distance of each user terminal. For the user terminal, each time wireless communication for transmitting data is performed, a large amount of power is consumed, and if the required number of repeated transmission is large, the power consumed for transmitting data is a non-negligible amount, so that it is necessary to reduce the number of transmission per se as much as possible to reduce the power consumption in data transmission.
Therefore, when the energy consumption of a certain user terminal in communication with the data storage server is large due to environmental restrictions, the user terminal can cooperate with a neighboring user terminal to perform data transmission.

Detailed Description
Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Fig. 1 is a schematic diagram of management data transmission between a data storage server and user terminals in a brain system of a city according to the present invention. As shown in fig. 1, wireless data transmission may be performed between the data storage server 100 and the first user terminal 200 and the second user terminal 300 in the urban brain system by using a mobile communication network, and communication may be performed between the first user terminal 200 and the second user terminal 300 by using a direct communication method between mobile terminals in addition to the mobile communication network.
Since one data storage server needs to respond to a plurality of user terminals, the data storage server dynamically allocates communication channel resources to each user terminal that requires transmission of management data, and requires different encoding schemes and data transmission times for each user terminal according to the distance of each user terminal. For the user terminal, each time wireless communication for transmitting data is performed, a large amount of power is consumed, and if the required number of transmission times is large, the power consumed for transmitting data is a non-negligible amount, so that it is necessary to reduce the number of transmission times per se as much as possible to reduce the power consumption during data transmission.
Fig. 2 is a flow chart of a method for transmitting management data in a brain system of a city according to the present invention. As shown in fig. 2, in step S110, when the first user terminal 200 needs to transmit the management data to the data storage server 100, a wireless communication link is first established with the data storage server 100, and then the system information transmitted by the data storage server 100 to the first user terminal 200 is received. The system information includes information such as a coding scheme used when data is transmitted and the number of times the first user terminal 200 is required to repeatedly transmit data.
The first user terminal 200 searches for a communicable neighboring second user terminal 300 and receives the second data transmission times that the data storage server requires the second user terminal 300 from the found second user terminal 300 at step S120. Here, the first user terminal 200 periodically transmits a terminal identification message to search for other user terminals in the vicinity, and the other user terminals receive the terminal identification message and transmit a response message generated in response to the terminal identification message to the first user terminal 200, thereby establishing a communication link between the two user terminals.
The communication between the first user terminal 200 and the second user terminal 300 may be a mobile communication network, or may be a communication method such as a local area wireless network, WIFI, bluetooth, or the like.
In step S130, the first user terminal 200 compares the first data transmission frequency with the second data transmission frequency, and determines whether to transmit the management data to be transmitted to the data storage server through the second user terminal according to the comparison result.
In step S140, when the first data transmission frequency of the first user terminal is greater than the second data transmission frequency of the second user terminal, it is determined to transmit management data through the second user terminal 300; and if the first data transmission times of the first user terminal is less than the second data transmission times of the second user terminal, continuously searching other adjacent user terminals, and comparing the transmission times to select the user terminal with the lower transmission time to transmit the management data. If no other user terminal available and having a lower number of transmissions is found finally, the first user terminal 200 transmits the management data directly to the data storage server in accordance with the first number of data transmissions.
Further, each user terminal may periodically search for a plurality of user terminals in the vicinity that can communicate, and store the number of transmissions received for each user terminal in the vicinity. When the first user terminal requires to provide the sending times, the sending times of the first user terminal and the sending times of other adjacent user terminals are sent to the first user terminal together, so that the searching time of the first user terminal is saved.
Further, the data storage server 100 may analyze a part of the received management data after starting to receive the management data transmitted from the user terminal, adjust the number of times of transmission of the management data in real time according to the communication status of the data storage server itself and the encoding status, the data type, the data size, the error rate, and the like of the received part of the management data, and transmit the adjusted number of times of transmission to the user terminal that is transmitting the management data.
As described above, the present invention transmits management data using a user terminal with a lower number of transmissions by comparing the number of transmissions between neighboring user terminals, thereby saving energy consumption of the user terminal when transmitting data.
