It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a flowchart of a method for sending a data packet according to an embodiment of the present invention, where the embodiment is applicable to a case where a data packet is sent, and the method may be executed by a radio frequency system.
When a data packet is sent through a radio frequency system, firstly, data can be packaged to obtain the data packet, then the data packet is sequentially sent to a Direct Memory Access (DMA) and a modulator, and then the data packet is sent through a sending circuit, wherein the DMA may refer to an interface technology in which external equipment directly exchanges data with a system Memory without a CPU, that is, the transmission speed of the data depends on the working speeds of a Memory and external equipment. The packaging comprises a series of processing, such as data encryption, check code addition, whitening and the like, so that the packaging of the data takes a long time for sending the whole data packet, and meanwhile, if the length of the sent original data is long, a radio frequency system is required to have strong data processing capacity.
Therefore, the embodiment of the invention provides a method for sending data packets, which is characterized in that data packets are packed into a plurality of data packets and sent to a modulation module after each data packet is packed, and then the modulation module modulates the received data packets into data packets to be sent in sequence and sends the data packets to a sending module, so that the efficiency of sending the data packets is improved.
As shown in fig. 1, the method includes:
s110, the data packet module packages the original data into a plurality of data packets and sends the data packets to the modulation module after each data packet is packaged.
The type of the original data is not limited, and may be, for example, image data, audio data, or the like. The data packet may include a sync word, a header, packet contents, etc., the sync word may be used to align data and determine whether the data is valid data, the header may be used to store packet type, length, etc., and the packet contents may be understood as valid data in the data packet.
Specifically, the data packet module may package the original data into a plurality of data packets and send the data packets to the modulation module after each data packet is packaged. The specific steps of grouping into a plurality of data packets are not limited in this embodiment, for example, the original data may be grouped according to length, and then the original data of each group may be grouped into a corresponding data packet. It should be noted that, in this embodiment, the order of the packet module to perform the packet packaging and send the data packet to the modulation module is not limited, for example, the packet module may perform the packet packaging of the next data packet while sending the current data packet to the modulation module, and this embodiment does not limit this.
And S120, the modulation module receives the data packets in sequence, modulates the received data packets into data packets to be sent, and sends the data packets to the sending module.
The modulation module may be regarded as a module for modulating the received data packet, and may include a first-in first-out unit, a modulator, and the like. A First Input First Output (FIFO) unit can firstly implement buffering of a data packet, preventing data loss during machine entry and storage operations; secondly, when the data packets are gathered for stacking and storing, frequent bus operation can be avoided, and the burden of the CPU is reduced, so that the FIFO unit is gradually and widely applied to high-speed data acquisition, high-speed data processing, high-speed data transmission and multi-machine processing systems due to the characteristics of flexibility, convenience and high efficiency. In this embodiment, the fifo unit may be considered as a unit for carrying packets, that is, each received packet is sequentially sent to the modulator for modulation, for example, the fifo unit may send the first received packet to the modulator for modulation, and then send the second received packet to the modulator for modulation. The data packet to be transmitted can be understood as a data packet to be transmitted after the data packet is modulated, and the specific means of modulation is not expanded in this step.
Specifically, after the data packet module sends the data packet to the modulation module, the modulation module may sequentially receive each data packet, and modulate the received data packet into a data packet to be sent according to a certain sequence, and send the data packet to the transmission module, where the certain sequence may be, for example, a first-in first-out sequence, or a first-in last-out sequence. In this embodiment, a manner of sending the data packet to be sent to the sending module by the modulation module is not limited, for example, the modulation module may send the data packet to be sent to the sending module in units of bytes, and may also send the data packet to be sent to the sending module in units of bits, which is not limited in this embodiment.
And S130, the sending module sends the data packet to be sent.
The transmitting module may be considered as a module for transmitting a data packet to be transmitted, and the transmitting module may include a power amplifier, an antenna, and the like. For example, the sending module may first perform power amplification processing on a data packet to be sent through a power amplifier, and then send the data packet after power amplification through an antenna.
The method for sending the data packet provided by the first embodiment of the invention comprises the following steps: the data packet module is used for packaging original data into a plurality of data packets and sending the data packets to the modulation module after each data packet is packaged; the modulation module receives the data packets in sequence, modulates the received data packets into data packets to be sent and sends the data packets to the sending module; and the sending module sends the data packet to be sent. By using the method, the original data packet is packaged into a plurality of data packets and sent to the modulation module after each data packet is packaged, so that the efficiency of sending the data packets in the radio frequency system is improved, and the node for sending the data packets is prevented from being missed.
In one embodiment, the speed of the packet module for packing the packets is greater than the speed of the modulation module for sending the packets to be sent to the sending module.
In this embodiment, the speed at which the data packet module packages the data packet may be greater than the speed at which the modulation module sends the data packet to be sent to the sending module to ensure that the modulation module is not empty, and on this basis, when the data packet module packages the data packet, the modulation module sends the data packet to be sent to the sending module, so that the efficiency of sending the data packet in the radio frequency system is improved.
In one embodiment, the transmitting, by the modulation module, the data packet to be transmitted includes:
the modulation module sends the data packet to be sent to the sending module by taking the bit as a unit.
It can be understood that the data packet of the embodiment of the present invention may be transmitted according to a radio frequency communication protocol, the radio frequency communication protocol may be considered as a communication protocol to which the data packet transmission in the radio frequency system needs to comply, the radio frequency communication protocol may include an international RFID radio frequency common protocol standard (such as ISO/IEC18000 standard, ISO11785, EPC standard, etc.) and a 2.4G radio frequency private protocol, and the 2.4G radio frequency private protocol may be considered as a related standard of an Industrial, Scientific and Medical (ISM) frequency band based on 2.4G, which is autonomously developed and established by an individual, a small-scale community, or some countries. The synchronization word, the packet header and the packet content in the data packet are mainly aligned according to bytes, but in the 2.4G radio frequency private protocol, the synchronization word or the packet header may be required not to be aligned according to bytes, so that the modulation module can send the data packet to be sent to the sending module by using bits as a unit, so as to achieve flexibility of sending the data packet.
In one embodiment, the data packets are transmitted according to a radio frequency communication protocol.
In one embodiment, the radio frequency communication protocol comprises a 2.4G radio frequency proprietary protocol.
Example two
Fig. 2 is a flowchart of a data packet sending method according to a second embodiment of the present invention, where a relation between this embodiment and the above embodiments is that a modulation module sequentially receives each data packet, and modulates the received data packet into a data packet to be sent, and sends the data packet to the sending module, which is further embodied as: a first-in first-out unit in the modulation module receives the data packets from the data packet module in sequence and transmits the received data packets to a modulator in sequence; and a modulator in the modulation module modulates the received data packet into a data packet to be sent and sends the data packet to be sent to the sending module. As shown in fig. 2, the method includes:
s210, the data packet module packs original data into a plurality of data packets and sends the data packets to the modulation module after each data packet is packed.
S220, the fifo unit in the modulation module receives each of the data packets from the data packet module in sequence, and transmits each of the received data packets to the modulator in sequence.
Specifically, when the modulation module includes a first-in first-out unit and a modulator, the first-in first-out unit in the modulation module may sequentially receive each data packet from the data packet module, and sequentially transmit each received data packet to the modulator for modulation according to a sequence; then, the modulator in the modulation module can modulate the received data packet into a data packet to be sent, and send the data packet to be sent to the sending module for sending.
The manner in which the fifo unit in the modulation module transmits the data packet to the modulator is not limited, and may be determined based on, for example, the alignment manner of the data packet, or the length of the data packet, which is not limited in this step.
S230, the modulator in the modulation module modulates the received data packet into a data packet to be sent, and sends the data packet to be sent to the sending module.
And S240, the sending module sends the data packet to be sent.
A data packet sending method provided in the second embodiment of the present invention includes: the data packet module is used for packaging original data into a plurality of data packets and sending the data packets to the modulation module after each data packet is packaged; a first-in first-out unit in the modulation module receives the data packets from the data packet module in sequence and transmits the received data packets to a modulator in sequence; a modulator in the modulation module modulates a received data packet into a data packet to be sent and sends the data packet to be sent to the sending module; and the sending module sends the data packet to be sent. By using the method, the received data packets can be sequentially transmitted to the modulator through the first-in first-out unit, and the received data packets are modulated into the data packets to be sent through the modulator, so that the data packets to be sent are sent to the sending module to realize the sending of the data packets.
In one embodiment, the fifo unit and the inter-modulator transmission unit are determined based on an alignment of packets.
In this embodiment, the alignment manner of the data packet may be understood as the alignment manner of the sync word, the header and the packet content in the data packet, for example, the alignment manner of the sync word, the header and the packet content in the data packet 1 is byte alignment; the sync word in the data packet 2 is aligned according to the bit, and the alignment mode of the packet head and the packet content is aligned according to the byte, etc.
Specifically, the transmission unit between the fifo unit and the modulator may be determined based on an alignment manner of the data packet, and for example, if the alignment manner of the sync word, the header, and the packet content in the data packet 1 is byte-aligned, the fifo unit may sequentially transmit each data packet to the modulator in units of bits.
In one embodiment, the fifo unit sequentially transmits each of the packets to the modulator in units of bits.
It is understood that in the 2.4G proprietary protocol, it may be required that the sync word or the packet header in the data packet is not byte-aligned, in which case it is not possible to transmit the data packet byte by the fifo unit and the modulator, so that it is necessary to transmit the data packet by bit, i.e. the fifo unit sequentially transmits each data packet to the modulator by bit.
It can be seen from the above description that in the rf system, the gap between data reception and data packet transmission is often very small, so that the rf system is required to process the received data and the transmitted data packet fast enough to avoid missing the time point of transmitting the data packet. And when the length of the data to be sent is longer, the time for packaging the packets is often longer, and the time point for sending the data packet may be missed due to too long time occupied by adopting a mode of packaging first and sending second, but the mode for sending the data packet by using the edge group wrapping provided by the embodiment of the invention can avoid the situation, so that the speed of packaging the packets is only required to be ensured to be faster than the speed for sending the data packet, and therefore, the time for sending the data packet can be fully utilized, and the subsequent data to be sent is synchronously processed in the process of sending the data packet.
Fig. 3 is a schematic diagram of a structure for transmitting a data packet according to a second embodiment of the present invention, as shown in fig. 3, a data packet module packages original data into a plurality of data packets and transmits the data packets to a FIFO (first-in first-out unit) in a modulation module after each data packet is completed; the first-in first-out memory receives the data packets from the data packet module in sequence and transmits the received data packets to the modulator in sequence; the modulator in the modulation module modulates the received data packet into a data packet to be transmitted, and transmits the data packet to be transmitted to a transmission circuit (i.e., a transmission module), and finally the transmission module transmits the data packet to be transmitted. In order to implement edge group wrapping transmission of a data packet, the embodiment of the present invention sets the FIFO in units of bits, so that when a data packet module transmits a data packet to the FIFO, as long as there is a data packet in the FIFO, the data packet to be transmitted can be automatically transmitted from the FIFO to the transmission circuit in units of bits, that is, it is only necessary to ensure that the FIFO is not empty from the beginning of transmitting the data packet to the end of transmitting the data packet.
