The external transceiver antenna is arranged outside the signal transceiving chamber and used for establishing communication with the communication base station 310, and the internal transceiver is arranged inside the signal transceiving chamber and used for establishing communication with a mobile terminal inside the transceiving chamber; the general motor train unit does not have a transceiver room, and the signal transceiver room can play a role in centralized output for signals, and the signal can be ensured to pass through the wall of the motor train unit to reach outdoors, so that the signal strength is improved. The processing module 120 mainly implements the processing function, which is described in detail below.
The processing module 120 is configured with a first communication interface policy, a data transmission policy, and a data reception policy;
the first communication interface strategy is used for establishing a communication interface between the built-in transceiver and a corresponding mobile terminal, and if a signal transceiver is required to be used in a transceiver room, the first step is to establish the communication interface, that is, to connect the mobile terminal 200 with the signal transceiver, and specifically includes establishing the communication interface, that is, connecting the mobile terminal 200 with the signal transceiver
A connection access step, in which the mobile terminal and the built-in transceiver establish connection through Bluetooth; first because bluetooth connection distance is shorter, the agreement of bluetooth simultaneously and have the authentication function, so carry out authentication, simple effective through the bluetooth. Specifically, the mobile terminal 200 may be configured with an authentication module, and configured to input authentication information to the authentication module through the mobile terminal 200, and the connection accessing step further includes that the mobile terminal 200 sends the authentication information to the processing module 120 through bluetooth. The verification information can be understood as a password, so that the password is simple and convenient, a better verification effect can be achieved after the password passes verification, and the reliability of verification is ensured. And then the subsequent steps are performed.
A connection configuration step, in which the mobile terminal generates first communication information according to equipment information of the mobile terminal and sends the first communication information to a corresponding built-in transceiver through the Bluetooth, wherein the first communication information comprises a network address of the mobile terminal and a communication frequency point of the mobile terminal; it should be noted that, first, communication protocols corresponding to each mobile terminal may be different, so that when the signal transceiver needs to be authorized for use, parameters of the mobile terminal need to be acquired, so that the mobile terminal sends the first communication information to the built-in transceiver through bluetooth, so that the built-in transceiver can be connected with the mobile terminal, it should be noted that the mobile terminal needs to install a corresponding APP program to call the data to complete connection, and through such setting, the built-in transceiver can adjust the receiving frequency and the sending frequency to complete communication with the mobile terminal, and it should be noted that communication establishment does not need to modify communication data, only needs to acquire original data, and details are not given herein.

And the processing module 120 performs data transmission and data reception.
The data transmission strategy is used for transmitting the first uplink data of the mobile terminal to the corresponding communication base station 310, and it should be noted that there is a certain difference from a general mobile communication connection mode, because the mobile terminal is on the motor train unit, the physical position of the mobile terminal changes according to the operation of the motor train unit, and the base station to which the mobile terminal is connected is different under the condition of high operation speed of the motor train unit, but the connection mode of the invention only needs the mobile terminal to correspond to one signal transceiver device, and the signal transceiver device is connected with other base stations (the base station corresponding to the original communication mode of the mobile terminal is generally unchanged, and the cost for reestablishing the connection is borne by the signal transceiver device), so that, because the signal transceiver device is managed uniformly, the verification algorithm can be simplified, and the security can still be ensured (the signal transceiver device can be understood as a mobile secondary base station), the first uplink data includes a network address of the mobile terminal, and specifically includes
A data uploading step, in which the mobile terminal uploads first uplink data to be sent to the processing module 120 through a built-in transceiver; by so setting, the transmission data is first transmitted to the processing module 120.

And the second is to modify the data format, so that the processed data needs to configure a corresponding analysis algorithm in the mobile interactive network to obtain the first uplink data again, which is higher in confidentiality but affects the data transmission efficiency.
A data sending step, in which the external transceiving antenna sends the second uplink data; the effect of data transmission can be achieved by transmitting the second uplink data through the external receiving and transmitting antenna, and the reliability of the data is ensured.
The data receiving strategy is used for sending the first downlink data of the communication base station 310 to the corresponding mobile terminal, and the principle is the same, and in the data receiving process, the communication base station 310 needs to acquire the position of the signal receiving and sending device to play a signal receiving and sending effect
A data receiving step, in which when the network address corresponding to the first downlink data is the same as the network address corresponding to the processing module 120, the external transceiving antenna receives the first downlink data; when the first downlink data is generated, there is a network address corresponding to the processing module 120, so that the data can be sent to the corresponding network address.
A step of processing received data, in which the processing module 120 processes the first downlink data according to a network address corresponding to the processing module 120 to obtain second downlink data, where the second downlink data includes a network address of the mobile terminal; the second downlink data obtained through the first downlink data processing may be directly sent to the mobile phone terminal, the mobile phone terminal may receive the second downlink data through an original receiving method, a data format of the first downlink data may also be the same as that of the second downlink data, and processing methods such as encryption may be performed during the first downlink data processing, which is not specifically described herein.
And a data downloading step, wherein the built-in transceiver sends the second downlink data to the corresponding mobile terminal. In this way, the reception of data is completed.
And the working frequency point of the mobile terminal is randomly generated in the working frequency band of the mobile terminal through a random algorithm. By randomly generating the working frequency points, the data security can be improved.
In another embodiment, the system further comprises a data server 410, the data server 410 is disposed in a data network, the data server 410 is configured with a base station positioning policy, and the base station positioning policy comprises
A base station data table establishing step, namely establishing a positioning data table according to the operation parameters of the motor train unit and the position of the communication base station 310, wherein the positioning data table comprises a plurality of positioning data, each positioning data comprises a motor train unit number item, a time item and a corresponding base station service item, the motor train unit number item reflects the number of the motor train unit, the time item reflects the time of the day, and the base station service item reflects the motor train unit number item and the base station network address of the corresponding communication base station 310 under the time item; as another key point of the invention, the base station positioning strategy can greatly improve the interaction effect of data, because in general, the coordination relation of data transmission needs to be reestablished corresponding to different base stations, and a data interaction effect is improved, the base station data table aims at the position of the motor train unit, and because the motor train unit runs strictly according to the running regulation, the position of the motor train unit in the running process can be calculated according to time, so that the method is very simple, the data does not need to be returned through a plurality of base stations, and if the data needs to be descended, the most appropriate base station or base stations can be found to output the data.
A positioning judgment step, when a target network address of the data network is a first downlink data of the network address of the signal transceiver, if the size of the first downlink data is smaller than a preset reference data value, the first downlink data is sent through a base station positioning step; the positioning judgment step further comprises the step of sending the first downlink data through the dynamic positioning step if the size of the first downlink data is larger than a preset reference data value; if the data is too large, the motor train unit is easy to exceed the original position, so that the data transmission is stopped, connection needs to be reestablished, and the data transmission is complicated, so that the data volume is judged, and if the data volume is small, the data can be transmitted as one data, for example
And a base station positioning step, namely acquiring a corresponding motor train unit number according to the destination network address, screening corresponding positioning data according to the motor train unit number, acquiring a corresponding base station network address according to the current actual time and a time item in the positioning data, sending the first downlink data to the communication base station 310 corresponding to the base station network address, finding the corresponding motor train unit number through the destination network address, acquiring the position of the motor train unit according to the motor train unit number and the current time, and acquiring the corresponding positioning data in a positioning table, so that the downlink data can be sent to the network address of the corresponding communication base station 310, and the data occupation is reduced. (the original logic is that the mobile terminal 200A makes a request for data acquisition, and if the location of a changes beyond the coverage of the corresponding communication base station 310, data will be sent to the corresponding terminal only if a makes a request at another location).
The dynamic positioning step comprises the steps of splitting the first downlink data into a plurality of first downlink sub-data with the same target network address according to the size of the first downlink data, configuring theoretical sending time according to a preset transmission rate and the size of the first downlink sub-data according to the sequence of the first downlink sub-data in the first downlink data, obtaining a corresponding motor train unit number according to the target network address, screening corresponding positioning data according to the motor train unit number, obtaining a corresponding base station network address according to the theoretical sending time of each first downlink sub-data and a time item in the positioning data, and sending the corresponding first downlink sub-data to a communication base station 310 corresponding to the base station network address when actual time reaches the theoretical sending time; the data size is reduced by splitting one data into a plurality of sub data, when each data is calculated according to the data size of each sub data to be sent, the position of the corresponding motor train unit is ensured to be directly received, and the method is simple and convenient.
