In the prior art, a communication link is established with a receiving server based on an AP communication technology and a baseband, so as to perform data transmission. However, establishing a communication link with a receiving server based on the AP communication technology and the baseband requires a series of complex programs such as a serial multiplexing protocol, and the operation flow is complicated, and manual operation is required, which cannot be adapted to unattended communication equipment.

The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a structure of a data transmission system based on the present application will be explained:
the data transmission method, the data transmission device, the satellite module and the storage medium are suitable for the satellite module and achieve data transmission between the client and the server. Fig. 1 is a schematic structural diagram of a data transmission system based on the embodiment of the present application, and mainly includes a satellite module, a client, and a destination server. Specifically, the satellite module establishes a communication link with a target server according to communication request information after receiving the communication request information sent by the client, receives data to be transmitted sent by the client after the communication link is successfully established, and sends the data to be transmitted to the target server based on the control instruction set and the established communication link.
The embodiment of the application provides a data transmission method, which is applied to a satellite module and used for solving the technical problem that the data transmission efficiency of the data transmission method in the prior art is low. The execution main body of the embodiment of the application is a satellite module.
As shown in fig. 2, a schematic flow chart of a data transmission method provided in an embodiment of the present application is shown, where the method includes:
Specifically, after the satellite module is powered on, and when it is determined that the SIM card and other software and hardware devices are normal, currently available satellite beams are searched. The satellite beam includes an effective signal, and the effective signal refers to an available satellite signal carried by the satellite beam.
It should be explained that the activation process is performed after the completion of the network entry residence process.
Illustratively, according to the power of effective signals in satellite beams, the beams are sorted, the beam corresponding to the effective signal with the highest power is screened out, the broadcast information carried by the beam is received, and cells in the broadcast information are sequentially solved, so that important information of network access is obtained, and network access resident processing is performed. After the network access resident processing is finished, the downlink signal carrier-to-noise ratio of each wave beam is calculated according to the absolute power, the background noise value and other related data of the effective signals in each wave beam, each wave beam is sequenced according to the downlink signal carrier-to-noise ratio, the wave beam which is most suitable for transmitting the packet domain service is determined according to the sequencing result, and the activation processing is carried out based on the wave beam. When the beam cannot successfully complete the activation processing or cannot perform the packet domain service for a long time, the beam used for the activation processing is reselected and the activation processing is performed again.
It should be explained that, before data transmission, the client sends a communication request message to the satellite module to prompt the satellite module to establish a communication link with the destination server.
And step 204, establishing a communication link with the destination server according to the communication request information.
Specifically, after the satellite module performs the network access residence processing and the activation processing, the communication link connection layer of the satellite module is ready, and the network transport layer protocol starts to try to establish a communication link with the target server according to the received communication request information.
It should be explained that, the satellite module provided in the embodiment of the present application integrates the functions of the AP processor into the CP processor, so that the satellite module does not need the AP processor, peripheral circuits, supporting devices, and the like, and has the advantages of small size, high integration level, and the like.
Illustratively, the step of establishing a communication link with the target server may comprise: and establishing handshake connection between the socket client of the network side opposite end and the target server, and performing instantiation processing on a transmission protocol of a TCP/IP network layer of the self. Establishing TCP/IP connection according to the acquired information such as the destination IP address, the port number and the like of the network layer opposite end of the client, searching the destination address in the network through the address information, trying to perform socket connection communication with the destination address, and determining that the complete communication link is connected after socket connection is completed and handshake is successful.
Specifically, after the communication link is successfully established, the data to be transmitted sent by the client is acquired based on the local serial port, wherein the data to be transmitted is transmitted in a data code stream mode.
It should be explained that the preset control instruction set is a self-defined AT instruction, and a Point-To-Point protocol (PPP) link with the destination server and a serial data channel are implemented based on the self-defined AT instruction. The user-defined AT instruction (namely a preset control instruction set) can be set according to actual conditions, so that the data transmission method provided by the embodiment of the application is suitable for various application scenes, and the universality of the data transmission method is improved.
On the basis of the above embodiment, the satellite module provided in the embodiment of the present application is used for receiving data to be transmitted sent by a client, and then sending the received data to be transmitted to a destination server, that is, the satellite module forwards the data to be transmitted. Therefore, the situation of data packet loss is inevitable, and the safety and reliability of data transmission are not guaranteed.
In order to solve the foregoing problems, fig. 3 is a schematic flow chart of another data transmission method provided in this embodiment of the present application, and as an implementable manner, on the basis of the foregoing embodiment, in an embodiment, sending data to be transmitted to a destination server according to a preset control instruction set and an established communication link includes:
It should be explained that, because the data transmission method provided in the embodiment of the present application is based on an air interface link protocol to send data to be transmitted to a destination server, and the transmission rate of the data is limited, to avoid that the data to be transmitted exceeds the maximum limit of the transmission rate, so as to improve the security of data transmission, before data transmission, the data to be transmitted is cached, and then the cached data is sequentially sent to the destination server.
After receiving the data to be transmitted, the destination server sends a feedback signal with the identifier of the data to be transmitted to the satellite module to prompt the satellite module that the data to be transmitted is successfully received. And for the data to be transmitted which has not received the corresponding feedback signal all the time, performing packet loss retransmission processing on the data to be transmitted, namely, re-sending the data to the target server until the corresponding feedback signal is received. The data transmission method avoids the situation of data packet loss and improves the reliability of the data transmission method.
Exemplarily, after data to be transmitted sent by a client is received, security detection is performed on the data to be transmitted first, wherein the security detection is mainly used for detecting whether malicious character strings exist in the data to be transmitted, that is, the data transmission system provided by the embodiment of the present application is prevented from being attacked maliciously, so that the security of the data transmission system is improved. After the data to be transmitted is determined to pass the security detection, namely malicious character strings which can cause potential safety hazards to a data transmission system do not exist in the data to be transmitted, caching the data to be transmitted, and sequentially sending the data to be transmitted to a target server according to the caching sequence of the data to be transmitted.
On the basis of the foregoing embodiment, in order to further improve the security and reliability of the data transmission method, as an implementable manner, on the basis of the foregoing embodiment, in an embodiment, before acquiring data to be transmitted sent by a client, the method further includes:
When the communication link is determined to be successfully established, the step of acquiring the data to be transmitted sent by the client is executed (step 205).
For example, after the communication link is established with the destination server, a test signal is sent to the destination server according to a preset period, and if a feedback signal fed back by the destination server is received, it is determined that the communication link is established successfully, that is, the communication link is in a connected state.
The interruption of the communication link is usually embodied in abnormal connection or interruption of the network layer or the air interface data transmission layer, that is, detecting whether the abnormal connection or the interruption occurs in the network layer or the air interface data transmission layer is equivalent to detecting whether the interruption occurs in the communication link. Therefore, in order to ensure the security of data transmission, the current state of the network layer or the air interface data transmission layer needs to be detected in real time. Since the duty cycle of the network layer is smaller than the duty cycle of the air interface data transmission layer, when the connection state of the detection link is detected according to the preset time interval, the preset time interval can be set according to the duty cycle of the network layer.
Correspondingly, the method further comprises the following steps:
It should be explained that there are various failure factors that may cause a communication link to be unsuccessfully established, and therefore, if a failure is determined to occur, it is necessary to perform failure detection on the failure to determine the type of the failure, the cause of the failure, and the like, so that a relevant operator can select a targeted failure recovery scheme according to the failure detection result.
Specifically, in an embodiment, in order to improve the accuracy of the fault detection result provided in the embodiment of the present application to help a relevant operator to select a targeted fault repairing scheme, as shown in fig. 5, a schematic flow chart of another data transmission method provided in the embodiment of the present application is provided, as an implementable manner, on the basis of the above embodiment, the fault detection specifically includes:
the fault detection data comprises a fault type and a fault occurrence reason;
It should be noted that the recoverable fault mainly refers to communication link interruption, communication link connection failure, and the like, and the recoverable fault refers to a fault that can be repaired by reestablishing the communication link.
The fault types mainly include SIM card arrearage, network fault, signal abnormality, no idle wave beam resources, communication link interruption, communication link connection failure and the like.
For example, for a fault with a fault type of interruption of the communication link, the fault may occur because the communication link is in an idle state for a long time, which results in automatic disconnection of the communication link, and at this time, the satellite module may automatically reconnect the communication link to implement fault repair. For a fault of which the fault type is a communication link connection failure, the communication request information sent by the client, which can be acquired due to the fault, is abnormal, for example, a destination server cannot be determined according to the communication request information, or the satellite module fails to be activated, and the like, at this time, the satellite module can automatically reactivate the satellite module, or the communication request information sent by the client is acquired again, so as to realize fault repair.
Correspondingly, the method further comprises the following steps:
The unrecoverable faults mainly include SIM card arrearage, network faults, signal abnormalities, no idle beam resources and the like.
Specifically, after determining that the occurred fault is an unrecoverable fault, in order to avoid that the client continues to send the data to be transmitted to the satellite module under the fault condition, offline processing is performed on the satellite module, for example, the client is rejected from receiving the data to be transmitted sent by the client. And meanwhile, fault information is generated and reported out to prompt the client and related operators that the satellite module has an unrecoverable fault.
On the basis of the above embodiment, when the communication link is in the idle state during the production time, the destination server releases the communication link, that is, the communication link is automatically disconnected, in order to ensure that the physical frequency band resource is not wasted for a long time. When new data to be transmitted needs to be transmitted based on the communication link, the communication link needs to be reconnected, that is, the connection between the network layer and the data transmission layer is reestablished, but the establishment of the connection needs a long time, which is not beneficial to ensuring the real-time performance of data transmission.
In order to solve the above problem, in an embodiment, a heartbeat signal may be sent to the destination server according to a preset period according to the control instruction set, so as to maintain the communication link in a connected state.
Illustratively, when it is determined that there is no data to be transmitted that needs to be transmitted, a heartbeat signal is sent to the destination server according to a preset period according to the control instruction set. In order to reduce the power consumption of the data transmission system, the preset period for sending the heartbeat signal may be slightly less than the limit value of the idle time of the communication link. For example, if the communication link is automatically disconnected when the communication link is in the idle state for 30 minutes, the preset period for sending the heartbeat signal may be set to 25 minutes.
When the heartbeat signal is sent, the satellite module can be in a dormant state, the dormant bottom current is 20mA, and the satellite module is automatically awakened when service is needed, so that the power consumption of the data transmission system is further reduced.
