or when the data is distributed, at least one communication module I in the plurality of communication modules is used for establishing connection with the micro base station to acquire the data, and at least one communication module II in the plurality of communication modules is used for exchanging the data between the terminals; and the second communication module is provided with two modes, namely an AP mode and an STA mode, wherein the AP mode is used for issuing the acquired data packet, and the STA mode is used for acquiring the required data packet from other terminals.
7. The heterogeneous network-based production line terminal data distribution method according to claim 5, wherein the step of judging whether the required data packet is available from terminal to terminal comprises:
judging whether an intersection between a complement of the data packet coding set of the first terminal and the data packet coding set of the second terminal is empty or not through the data packet coding sets of the two terminals, if so, the first terminal cannot obtain the required data packet from the second terminal, if not, the first terminal can obtain the required data packet from the second terminal, and the intersection is the data packet coding set which can be obtained from the second terminal.
8. The heterogeneous network-based production line terminal data distribution method according to claim 5, wherein the connection priority calculation of the micro base station comprises the steps of:
the network resource scheduling system records the connection condition of all the micro base stations, calculates the base station idle rate of each micro base station, and calculates the base station idle rate= (production line operation time length-micro base station data issuing time length)/production line operation time length; the higher the idle rate of the base station, the higher the connection priority of the micro base station.
9. The heterogeneous network-based production line terminal data distribution method according to claim 5, wherein the network control system calculates connection priorities of all terminals, and when a plurality of terminals receive the same micro base station signal, preferentially connects terminals with high priority;
the connection priority calculation of the terminal comprises the following steps:
the network control system records the data downloading conditions of all terminals, calculates the data downloading completion rate of each terminal, and the data downloading completion rate of the terminal= (single terminal data requirement-the downloaded data quantity of the terminal)/single terminal data requirement, and the lower the data downloading completion rate is, the higher the connection priority is.
10. The heterogeneous network-based production line terminal data distribution method according to claim 5, wherein when a terminal has acquired all data packets, the terminal still distributes data packets to other terminals.
