and if the second retransmission times are less than or equal to second preset retransmission times, sending the service response packet to the sending end equipment.
5. The method according to claim 4, wherein before the detecting whether the service response packet exists in the uplink packet sending buffer area according to the preset second retransmission interval time, the method further comprises:
inquiring an uplink packet sending cache region according to a transaction identifier in a service command packet sent by sending end equipment;
judging whether to process the service instruction packet;
and if the service instruction packet is not processed and the service corresponding to the service instruction packet is not related to lower-level equipment, storing a service response packet of the unprocessed service instruction packet in the uplink packet sending cache region.
6. The method of claim 4, further comprising:
receiving a second response notice sent by the sending end equipment under the condition that the sending end receives the service response packet;
analyzing the second response notice to obtain a transaction identifier;
searching whether a service response packet exists in the uplink packet sending cache region or not according to the transaction identifier and the fragment packet number in the service response packet;
and if the service response packet exists, deleting the service response packet.
7. An apparatus for retransmitting data, the apparatus comprising:
the first detection module is used for detecting whether service data exist in a downlink packet sending cache region or not according to a preset first retransmission interval time;
a first obtaining module, configured to obtain a service command packet corresponding to the service data in a cyclic manner when service data exists in the downlink packet sending buffer area, where the service command packet at least includes a first retransmission number;
and the first sending module is used for sending the acquired service command packet to the receiving end equipment if the first retransmission times are less than or equal to a first preset retransmission time.
8. An apparatus for retransmitting data, the apparatus comprising:
the second detection module is used for detecting whether a service response packet exists in the uplink packet sending cache region according to a preset second retransmission interval time;
a second obtaining module, configured to obtain a service response packet in a cycle when the service response packet is present in the uplink packet sending cache region, where the service response packet at least includes a second retransmission number;
and the second sending module is used for sending the service response packet to the sending end equipment if the second retransmission times is less than or equal to a second preset retransmission times.
9. A terminal device, comprising: at least one processor and memory;
the memory stores a computer program; the at least one processor executes the computer program stored by the memory to implement the data retransmission method of any of claims 1-3 or 4-6.
10. A computer-readable storage medium, characterized in that a computer program is stored in the computer-readable storage medium, which computer program, when executed, implements the data retransmission method according to any one of claims 1-3 or 4-6.
