Description
Technical Field
The present invention relates to a data transmission technique for an urban brain system, and more particularly, to a management data transmission method for transmitting management data between a data storage server performing wireless communication and a plurality of user terminals in the urban 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. In the case of a user terminal, a large amount of energy is consumed for each wireless communication for transmitting data, and if a large number of repeated transmissions are required, the amount of energy consumed for transmitting data is not negligible.
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.

The invention relates to a management data transmission method in an urban brain system, which transmits management data between a data storage server for wireless communication and a plurality of user terminals including a first user terminal and a second user terminal, and comprises the following steps:
step S110, storing information of the plurality of user terminals in the data storage server in advance, wherein the information comprises unit consumption energy consumed when each user terminal sends unit amount data to the data storage server;
step S120, the data storage server periodically communicates with the plurality of user terminals, confirms the communication state of each user terminal, and determines the data sending times when each user terminal sends the management data to the data storage server according to the communication state;
step S130, after the data storage server receives the data transmission request from the first user terminal, according to the stored data transmission times of the multiple user terminals and the unit consumed energy, comparing the consumed energy Es when the first user terminal and other user terminals transmit the management data to the data storage server, and determining the user terminal with the lowest consumed energy Es as the second user terminal, where the consumed energy Es is calculated according to the following formula:
Es = E0×Sd×N
wherein E0 is the unit energy consumption when the user terminal sends unit amount of data to the data storage server; sd is a size of management data to be transmitted calculated on the basis of the unit amount; n is the data transmission times of the user terminal required by the data storage server;
step S140, the first user terminal sends the management data to be sent and the number of times of sending the data of the second user terminal to the second user terminal, and then the second user terminal sends the management data to the data storage server.
Further, it is preferable that the data storage server adjusts the number of data transmission times of the management data in real time after starting to receive the management data transmitted from the second user terminal.
In addition, preferably, the plurality of user terminals communicate with each other by using a communication method of WIFI or bluetooth.

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, data transmission between the data storage server 100 and the first user terminal 200, the second user terminal 300, and other user terminals not shown in the figure in the urban brain system may be performed by using a mobile communication network, and communication between the first user terminal 200 and the second user terminal 300, and other user terminals may be performed 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 requests transmission of management data, and further, requests different encoding schemes and data transmission times for each user terminal according to communication year states such as the distance and idle state of each user terminal. In the case of a user terminal, a large amount of energy is consumed for each wireless communication for transmitting data, and if a large number of requested transmission times are required, the amount of energy consumed for transmitting data is not negligible.
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, information of each user terminal that can access the data storage server is stored in advance in the data storage server 100, and the information includes unit consumption energy that is consumed when each user terminal transmits unit amount of data to the data storage server. The unit energy consumption of each user terminal when transmitting a unit amount of data to the data storage server 100 can be measured in advance by a professional test method and stored in the data storage server 100.
Here, since the present invention is applied to the urban brain system, the user terminals that can access the data storage server are all limited user terminals that are allowed to access, and information of these user terminals can be obtained by measurement in advance.
In step S120, the data storage server 100 periodically communicates with each user terminal that can access the data storage server, confirms a communication state including a distance, an idle state, and the like of each user terminal, and determines the number of data transmission times when each user terminal transmits data to the data storage server according to the communication state.
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 a request for transmission of the management data is transmitted at step S130. After receiving the data transmission request from the first user terminal 200, the data storage server compares the energy consumption when each user terminal transmits the management data to the data storage server according to the stored data transmission times and unit energy consumption of the first user terminal and other user terminals, and determines the user terminal with the lowest energy consumption as the second user terminal 300. Here, the energy consumption Es when each user terminal transmits the management data to the data storage server can be calculated according to the following equation.
Es = E0×Sd×N
Where E0 is the unit energy consumption when the user terminal sends unit amount of data to the data storage server; sd is a size of management data to be transmitted calculated on the basis of the unit amount; n is the number of data transmissions of the user terminal required by the data storage server.
And, the data storage server transmits information about the second user terminal 300 and the number of transmission times (i.e., the second data transmission times) to the first user terminal 200.
Wherein if the transmission power consumption of the first user terminal 200 is the lowest as a result of the comparison, it is determined that the management data is directly transmitted to the data storage server 100 by the first user terminal 200. At this time, the data storage server 100 transmits a data transmission permission instruction and a first data transmission count to the first user terminal 200, and then the first user terminal 200 directly transmits the management data to the data storage server according to the first data transmission count.
Then, in step S140, the first user terminal 200 searches for the second user terminal 300 and establishes a communication connection, and transmits the management data to be transmitted and the number of times of transmission of the second data to the second user terminal 300. Next, the second user terminal 300 transmits the management data to the data storage server 100 according to the second data transmission number.
Further, it is preferable that the data storage server 100 analyzes a part of the received management data after starting receiving the management data transmitted from the user terminal, adjusts 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 part of the management data received, and transmits the adjusted number of times of transmission to the user terminal which is transmitting the management data.
Here, the communication between the first user terminal 200 and the second user terminal 300 may be performed by using a mobile communication network, or may be performed by using a communication method such as WIFI or bluetooth.
As described above, the present invention compares transmission power consumption between adjacent ues, and transmits management data using a ue with less transmission power consumption, thereby saving power consumption of the ue when transmitting data.
