Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the prior art, the POS machine adopts HTTP short connection to upload the acquired coordinate data in real time, and the following problems exist: (1) Because the HTTP short connection must contain header information, the data message length is large, consuming a lot of network resources; (2) the HTTP protocol transmission speed is slow. In the invention, the terminal adopts UDP (User Datagram Protocol ) protocol to send the message by default.
According to one aspect of an embodiment of the present invention, a method of distribution data acquisition is provided.
FIG. 1 is a schematic diagram of a main flow of a method for collecting distribution data according to an embodiment of the present invention, and as shown in FIG. 1, the method for collecting distribution data includes:
step S101, a receiving terminal sends a delivery data message based on UDP protocol;
step S102, analyzing the delivery data packet from the delivery data packet;
step S103, the distribution data packet is cached to a data buffer window.
By sending the message based on the UDP protocol, on one hand, the frequent establishment of connection can be avoided, the message length is greatly reduced, the network resource consumption is reduced, and the transmission speed is improved; on the other hand, the hardware resource consumption of the receiving end analysis message can be reduced, and the system stability is improved. In addition, based on a data buffering mechanism, protocol reliability can be ensured.
Optionally, after buffering the delivery data packet in the data buffer window, the method further includes: judging whether the quantity of the distributed data packets in the data buffer window in preset time meets a first preset condition or not; if yes, the terminal is controlled to send a delivery data packet cached to the next data buffer window by adopting a UDP protocol; otherwise, updating the retransmission times of the terminal, and controlling the terminal to retransmit the delivery data packet corresponding to the data buffer window.
The first preset condition can be selectively set according to actual conditions. In some embodiments, the first preset condition is that the number of the delivered data packets in the data buffer window in the preset time is equal to the buffer threshold of the data buffer window, for example, the buffer threshold of the data buffer window is N, and the number of the delivered data packets in the data buffer window in the preset time is also equal to N. In other embodiments, the first preset condition is that a ratio between the number of data packets delivered in the data buffer window and the buffer threshold of the data buffer window within a preset time is greater than or equal to a set ratio threshold, for example, the buffer threshold of the data buffer window is N, and the number of data packets delivered in the data buffer window within the preset time is also equal to 90% N.
And when the quantity of the distributed data packets in the data buffer window within the preset time meets the first preset condition, the current data buffer window is considered to be completely acquired, and the next data buffer window is slid to continuously acquire the distributed data.
When the quantity of the distributed data packets in the data buffer window in the preset time does not meet the first preset condition, updating the retransmission times of the terminal, and conveniently determining the UDP availability according to the retransmission times; and controlling the terminal to retransmit the delivery data packet corresponding to the data buffer window, so that the delivery data can be acquired to the maximum extent, and the problem of data loss caused by failure in receiving part of the delivery data packet is prevented.
Optionally, before controlling the terminal to retransmit the delivery data packet corresponding to the data buffer window, the method further includes: and determining the UDP availability according to the updated retransmission times, and if the UDP availability is smaller than a preset first threshold, adjusting the message protocol of the terminal to be a TCP protocol, see FIG. 2. When the UDP availability is smaller than a preset first threshold, the fact that the UDP protocol is unsuitable for sending the delivery data is indicated, for example, the transmission speed is low or the transmission fails, and the message protocol of the terminal is adjusted to the TCP protocol, so that the terminal can send the delivery data through the TCP protocol, the transmission speed is improved, and the reliability and the high availability of the protocol are guaranteed.
Optionally, after adjusting the message protocol of the terminal to the TCP protocol, the method further includes: and detecting UDP availability periodically, and adjusting the message protocol of the terminal to UDP protocol when the UDP availability is larger than a preset second threshold. By means of periodic detection, when the network environment is suitable for transmitting delivery data by adopting the UDP protocol, the message protocol of the terminal can be timely adjusted to the UDP protocol, so that on one hand, the frequent establishment of connection due to the adoption of the TCP protocol is avoided, the message length is greatly reduced, the network resource consumption is reduced, and the transmission speed is improved; on the other hand, the hardware resource consumption of the receiving end analysis message can be reduced, and the system stability is improved.
It should be noted that, the first threshold and the second threshold mentioned in the present invention may be selectively set according to actual situations. Typically, the first threshold is less than the second threshold. In an alternative embodiment of simultaneously adopting the first threshold and the second threshold to control the switching of the transmission protocol, assuming that the current UDP availability is T, the UDP protocol is currently used for transmitting the message, and T > the second threshold > the first threshold, if T is reduced to T ', the second threshold is more than or equal to T '. Gtoreq.first threshold, the UDP protocol is still used for transmitting the message until T ' < first threshold, and the TCP protocol is used for transmitting the message instead. Assuming that the current UDP availability is T, the TCP protocol is currently used for transmitting the message, and the second threshold value is greater than the first threshold value and greater than T, if T is increased to T', the second threshold value is greater than or equal to the first threshold value, the TCP protocol is still used for transmitting the message until the second threshold value is reached, and the UDP protocol is used for transmitting the message.
The invention can realize the switching of the transmission protocol based on the availability and the periodic detection mechanism, and ensure the high availability of the protocol.
Optionally, the delivery data packet includes the following fields: a terminal identification field, a verification field, a dispatcher identification field, a longitude field and a latitude field; wherein each field occupies four bytes. FIG. 3 is a schematic diagram of a UDP protocol message in an embodiment of the present invention, as shown in FIG. 3, the first 4 bytes of the delivery data message are stored CID; byte 5-8 stores RSN; byte 9-12 stores operators No; bytes 13-116 store longitude; bytes 17-20 store the latency. CID, client ID, represents the unique identity of the terminal. The RSN (Robust Security Network ) is used to verify user legitimacy. The RSN is an authentication identifier issued after a dispatcher logs in the system, the data carries the identifier in login timeliness to indicate that the user is legal, and if the identifier is inconsistent with the server, the RSN needs to be re-logged in and re-acquired. In FIG. 3, operator No represents the dealer identity, longitude represents accuracy, and latitude represents latitude.
