Communication method and device with coexistence of multiple communication modes

Abstract

The invention discloses a communication method and device in which multiple communication modes coexist, and relates to the field of optical distribution networks. The method includes: configuring a corresponding communication task for each data communication module in an RTOS, and forming a communication task queue for all communication tasks; When judging that the communication interruption signal of the data communication module is generated, open up a memory area and define it as a circular queue; judge that the circular queue is not full, and receive the communication data; store the communication data into the communication data storage unit; read the communication data The communication processing data of the unit is read, and the communication processing data is processed and sent through the corresponding communication interface. The invention has high working efficiency and low bit error rate, not only improves the working efficiency of the CPU, but also transmits data stably and reliably, and is convenient for users to use.

Description

technical field [0001] The invention relates to the field of optical distribution networks, in particular to a communication method and device in which multiple communication modes coexist. Background technique [0002] FTTH (Fiber-To-The-Home, fiber-to-the-home) mainly adopts PON (Passive Optical Network, passive optical network) technology, FTTH mainly includes OLT (optical line terminal, optical line terminal), ODN (OpticalDistribution Network, optical distribution Network) and ONU (Optical Network Unit, Optical Network Unit). The OLT is mainly used to connect the optical fiber backbone network to the ODN, and the ONU is used to output the ODN to the user port. The ODN opens up a transmission channel for optical fiber communication between the OLT and the ONU. The ODN is mainly composed of various ODN devices. play a key role in. [0003] With the pull of FTTH construction, the development speed of ODN is getting faster and faster. People use intelligent ODN technology ...

AI Technical Summary

Problems solved by technology

[0015] (1) When multiple communication methods coexist, the CPU needs to process the data transmitted by multiple communication interfaces at the same time, and the data transmitted by multiple communication interfaces may cause conflicts; the CPU not only has low work efficiency, but also is easy to get stuck, which is not convenient for people to use

[0016] (2) Since multiple communication methods may operate on shared data (located in the same memory unit) at the same time (that is, one communication interface stores the data in the memory, and the other communication interface processes the data in the memory accordingly), it may occur When the data processing corresponding to one communication interface has not been completed, another communication interface receives new data; if the receiving speed of the communication interface receiving new data is faster than the processing speed of the communication interface processing data, the server receives New data may overwrite historical data, resulting in data transmission errors and potential safety hazards

In order to prevent data transmission errors, data receiving and data processing can be operated separately, that is, data receiving operations and data processing operations corresponding to different communication methods are separately compiled into sub-functions, but separate sub-functions will make the logic in the main program Arrangements are difficult, and the work efficiency of program design is low
