Description

TECHNICAL FIELD

[0001] The present application belongs to the field of intelligent terminal communication software, and more particularly relates to a centralized downlink communication resource allocation system and method for intelligent terminals. BACKGROUND

[0002] The current intelligent terminal is developing rapidly, and in order to improve the reusability of functions, various functions are often deployed in an application manner, and the applications interact with each other through a message bus.

[0003] The intelligent terminal is a kind of terminal that connects the past and the future, and communicates with the meter and sensor through the downlink channel, and communicates with the master station through the uplink channel, so as to realize data acquisition, control and other functions. The downlink channel mainly includes Bluetooth, carrier, RS-485 and other interfaces.

[0004] In this process, the concurrent problem of multiple applications accessing the same downlink channel and the synchronization problem of the same application accessing multiple downlink channels often occur.

[0005] In order to solve the problems of management confusion, non-timely concurrent processing and the like in downlink communication, a centralized downlink communication resource allocation method for intelligent terminals is urgently needed. SUMMARY

[0006] The purpose of the present application is to solve the problems of concurrency and synchronization in downlink communication of intelligent terminals, and a centralized downlink communication resource allocation system and method for intelligent terminals are proposed. In the present application, the business application interacts with the downlink communication resource management application through the message bus, and sends a downlink channel interaction request; the downlink communication resource management application dynamically adjusts the resource allocation according to the business priority and the channel load state, including the optimization configuration of access permission and communication load.

[0007] The technical scheme of the present application is:

[0008] The present application provides a downlink communication resource allocation system for intelligent terminals, characterized in that it comprises:

[0009] A downlink communication resource management application is used to acquire and uniformly manage the downlink communication channel resources of the intelligent terminal, and dynamically adjusts the resource allocation according to the business request priority sent by the business application and the load state of the communication interface;

[0010] A message bus is used for data interaction between the business application and the downlink communication resource management application.

[0011] Further, the downlink communication channel includes a carrier channel, a 485 communication channel and a Bluetooth communication channel.

[0012] Further, the business applications include marketing, power distribution business collection applications; the business applications communicate with each other in a message bus mode, in a one-to-one mode, a many-to-one mode or a one-to-many mode.

[0013] Further, the downlink communication resource management application performs the following steps:

[0014] Obtaining the interactive request content sent by the business application, including the target downlink communication channel, the request message, the timeout time and the request priority; generating an interactive request queue based on the request priority for each downlink communication channel involved;

[0015] Obtaining the available state of the downlink communication channel, if available, assigning channel resources to different interactive requests in the priority order of the interactive request queue; if overloaded, executing a timeout strategy.

[0016] Further, the available state of the downlink communication channel specifically includes:

[0017] Obtaining the current data bandwidth and the theoretical maximum bandwidth of the downlink communication channel;

[0018] According to the ratio of the current data bandwidth to the theoretical maximum bandwidth, calculating the load rate of the downlink communication channel, which is used to evaluate the usage degree of the channel resources;

[0019] If the load rate reaches a preset threshold, it is determined to be overloaded; otherwise, it is determined to be available.

[0020] Further, the timeout strategy includes: first executing the low-priority interactive request that is about to timeout, and then executing the high-priority interactive request.

[0021] A method adopted by an intelligent terminal downlink communication resource allocation system, comprising:

[0022] The business application sends an interactive request to the downlink communication resource management application through a message bus, and the interactive request content includes a target downlink communication channel, a request message, a timeout time and a request priority;

[0023] The downlink communication resource management application accepts the interactive request sent by the business application, updates the interactive request queue based on the request priority for each downlink communication channel involved, and initially generates the interactive request queue;

[0024] The downlink communication resource management application obtains the available state of the downlink communication channel, and sends the interactive request to the downlink communication channel involved according to the priority order of the interactive request queue;

[0025] The downlink communication resource management application obtains the response message of the downlink communication interface and feeds back to the corresponding business application through the message bus.

[0026] The service application processes the received interaction request response to complete an interaction.

[0027] Further, the available state of the downlink communication channel is acquired, and when the channel is overloaded, a low-priority request is processed based on a timeout strategy.

[0028] Further, a load rate of the downlink communication channel is calculated according to a ratio of a current data bandwidth to the theoretical maximum bandwidth, and if the load rate value reaches a preset threshold, it is determined that the downlink communication interface is in an overloaded state.

[0029] Further, before the downlink communication resource management application acquires the available state of the downlink communication channel, the interface state of the downlink communication channel is acquired, and if it is abnormal, a reset operation is performed to re-open the corresponding interface for initialization.

[0030] Advantages of the present application:

[0031] The intelligent terminal centralized downlink communication resource allocation system and method can realize unified management of downlink communication resources of carriers, 485, Bluetooth channels and other intelligent terminals, realize sharing of downlink communication resources, and ensure that each channel can complete communication tasks efficiently and orderly according to different business types.

[0032] In the present application, message bus technology is used for data interaction between multiple applications. The service application sends an interaction request of the downlink communication interface to the downlink resource management application for unified management through the message bus.

[0033] In the present application, the downlink resource management application can control the priority of the communication interface interaction request, monitor the load of the communication interface, and protect the communication interface from abnormality, thereby realizing high-reliability and high-performance centralized management.

[0034] The present application also supports attempting to respond to low-priority requests when the channel is full, balancing high-priority and low-priority requests through a timeout strategy, reducing the probability of interaction failure, realizing efficient use and flexible allocation of downlink communication resources, ensuring orderly completion of communication tasks, and improving the overall communication efficiency of the intelligent terminal.
