Data communication method and device

Abstract

The present invention discloses a data communication method and apparatus, and relates to the technical field of communications. The method comprises: when an APP is running, establishing a data link; creating a send task pool and a receive task pool; based on a task sending priority rule, acquiring first data from the send task pool, and sending the first data to a bottom-layer communication service terminal by means of the data link; receiving second data sent by the bottom-layer communication service terminal by means of the data link, and adding the second data into the receive task pool and performing corresponding processing; and when the APP exits, closing the data link. According to the communication method and system disclosed by the present invention, the queuing mechanisms of data transmission and reception can be controlled, so that data can be sent and received in order, multi-thread and multi-link concurrency quantity of data communications can be effectively controlled, the communication process can be optimized, the service life of hardware can be prolonged, problems such as hardware fever caused by concurrency of multiple threads and multiple data links can be solved, and security of work and user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data communication method and device. Background technique [0002] With the continuous development of smart home technology, smart home terminals are no longer limited to mobile phones and tablet computers, but also support embedded terminal controllers. The communication in the embedded terminal controller is based on the communication between the application layer and the bottom layer in the OSI seven-layer protocol model. The embedded APP is installed in the controller, and the APP needs to communicate with the bottom layer quickly and efficiently, including status query and control etc. At present, the communication mode of embedded APP is based on UDP, TCP, HTTP / HTTPS, etc. The basic principle is to create a new socket and send and receive data by specifying IP and port. Some communication links are long connections and some are short connections. A short...

Problems solved by technology

The communication link of long connection or short connection will lead to many and complicated threads for sending and receiving data in the APP or the underlying program, and the number of data links is also large due to different functions. When optimizing the program, multi-thread and multiple data links The management of the road is particularly complicated, and in the actual use process, due to the concurrency of multi-threading and multi-data links, it is easy to cause problems such as high occupancy rate of system CPU resources, high temperature of the circuit board, and short service life of the hardware.
