Detailed Description
The technical scheme of the invention is further explained in detail by combining the drawings in the specification.
The invention comprises the following steps:
1) when the concentrator has a plurality of acquisition tasks, the plurality of acquisition tasks are issued to the CAC at one time;
2) after the CAC receives the tasks, the tasks are cached in the CAC;
3) CAC screens the caching tasks, selects a plurality of tasks irrelevant to the route and sends the tasks to a collector; a plurality of tasks run concurrently in the network;
4) when the tasks in the network are completed, the CAC selects acquisition tasks irrelevant to the routes of the rest tasks from the cache tasks and sends the acquisition tasks to the acquisition device, so that the tasks with set number in the network run in parallel, and then the CAC deletes the finished tasks from the cache of the CAC; if the concentrator has the collection tasks which are not sent to the CAC and the number of the tasks cached in the CAC at present is less than the specified maximum number of the tasks, the collection tasks are immediately sent to the CAC, and the number of the tasks cached in the CAC is ensured.
By optimizing the technical scheme, the meter reading process comprises the following steps:
1. firstly, when a concentrator has a plurality of collection tasks, the collection tasks are sent to a CAC (the maximum task number is temporarily specified to be 100) at one time, the CAC caches the tasks after receiving the tasks, because the collection operation aiming at the same destination address exists in the tasks and the corresponding routes are the same, the CAC screens the tasks according to a certain rule, 5 irrelevant tasks with routes are selected and sent to the collector, in order to reduce the conflict among the tasks to the maximum extent, the 5 tasks are sent one by one according to a certain mechanism, and then the 5 tasks run concurrently in the network. When the tasks in the network are completed, the CAC selects the acquisition tasks irrelevant to the routes of the rest tasks from the cache tasks and sends the acquisition tasks to the acquisition device, 5 tasks in the network are ensured to run in parallel, and then the CAC deletes the finished tasks from the cache of the CAC. Meanwhile, the concentrator makes an appointment with the CAC, if the concentrator has acquisition tasks which are not issued to the CAC and the number of the tasks cached in the CAC at present is less than the specified maximum number of tasks 100, the acquisition tasks are immediately issued to the CAC, and the number of the tasks cached in the CAC is ensured. In the process of screening the tasks, the CAC has the condition that no 5 routes are completely irrelevant to acquire the tasks, the CAC can still execute the tasks according to the regulations, and if the tasks fail, the concentrator can issue the tasks again according to a certain mechanism. The effect under normal conditions is that if more than 100 tasks are not processed, 100 tasks are guaranteed to be processed or being processed in the CAC cache, and 5 tasks are guaranteed to run in parallel in the wireless network.
2. The realization of the asynchronous communication of the network is considered from two aspects of the processing mechanism between the concentrator and the CAC and the processing mechanism between the CAC and the collector.
The method mainly shows a specific implementation process from two aspects of a concentrator and CAC;
as shown in fig. 3: after the CAC receives the tasks issued by the concentrator, whether the number of the cache tasks per se is greater than or equal to the set maximum number of tasks 100 is judged, if the number of the cache tasks per se is less than the set maximum number of tasks, the CAC caches the acquisition tasks issued by the concentrator, whether the tasks with the set number are executed in the downlink network is judged, and otherwise, whether the tasks with the set number are executed in the downlink network is directly judged. If the downlink network is less than 5 tasks being executed, the CAC screens out tasks irrelevant to the tasks being executed from the cache tasks and sends the tasks to the collector to ensure the number of network tasks; the CAC then determines the execution status of the task being executed and deletes the completed task in the cache.
As shown in fig. 4, when the concentrator has an acquisition task, the number of tasks cached in the CAC is read at regular intervals; when the CAC cache task number is smaller than the set maximum task number, the concentrator issues acquisition tasks to the CAC until the task number in the CAC reaches the set maximum task number or no acquisition tasks exist in the concentrator.
As shown in fig. 2, the electric power centralized meter reading system includes a master station, a concentrator downlink main module, an electric meter and an electric meter module, the concentrator downlink main module and the electric meter module form a mesh network, each node in the mesh network has a path to a cac, and the cac can read data of the node through the path when the concentrator reads the electric power; the CAC selects a plurality of tasks with irrelevant routes to be issued to the collector, so that the conflict among the tasks is reduced, and the tasks are processed in parallel, thereby effectively improving the efficiency.
As shown in fig. 5, it is a basic component of a meter reading system, 1 concentrator and n collectors are installed in one cell, and 1 to 32 electric meters can be connected to the lower side of one collector; the dotted line is framed by an acquisition network consisting of a concentrator and an acquisition unit, wherein the concentrator communicates with the acquisition unit through a wireless signal by using a downlink communication module (also called CAC) installed on the concentrator. The CAC is an accessory that constitutes the concentrator and is responsible for downstream communications, i.e., for collecting meter data.
The method for improving the communication efficiency of the mesh network application shown in fig. 2 to 5 is a specific embodiment of the present invention, which already embodies the substantial features and improvements of the present invention, and can make equivalent modifications in shape, structure, etc. according to the practical use requirements, and is within the scope of the present invention.
