Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and the accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not used as limiting the present invention.
Example 1: the heterogeneous system data communication interaction method based on the central platform, as shown in fig. 1 and fig. 2, includes the following steps:
s1: establishing a ring queue, and dividing the ring queue into a write queue and a read queue;
s2: receiving target data uploaded by a heterogeneous system in a multiplexing method through a selector;
s3: initializing an event instance written into an empty queue in the queue to convert the event instance into a public action;
s4: writing target data into an empty queue, establishing corresponding actual event actions by combining the public actions and the target data, and updating a write queue and a read queue;
s5: and reading the actual event action in the queue by calling the idle thread in the thread pool, controlling the event processor to process the actual event action, and restoring the corresponding actual event action into a public action after the actual event action is processed.
The invention processes the received target data in a mode of combining the annular queue and the thread pool, initializes the annular queue when the system is started, fills the default event example, reduces the instantiation process of the subsequent received data event, changes the time by space, fully utilizes the hardware resource, rapidly processes the received target data by the limited and controllable memory size, and improves the data processing speed. In addition, the invention balances the data request demand degree of the sending end and the data handling capacity of the receiving end in a mode of alternately processing the write-in queue and the read-out queue in the circular queue, namely reduces the data amount of response processing of the data upload request, and also avoids the condition that the receiving end calls a large number of threads to process the uploaded target data, thereby causing abnormal other services of the receiving end.
As shown in fig. 2, the update process of the write queue and the read queue specifically includes: head identifiers and tail identifiers which are arranged at intervals are embedded in the circular queue, A in the figure 2 is the head identifier, B is the tail identifier, and the queues corresponding to 1-7 in the figure are reading queues; the positions of the head identifier and the tail identifier are adjusted, the write-in queue and the read queue are updated in a circulating rotation mode, whether the queues are full or not can be quickly known, and the data write-in and read efficiency is improved
The process of writing the target data into the vacant queue specifically comprises the following steps: acquiring estimated processing time of target data; sequencing the target data of the same write-in batch according to the estimated processing time; and sequentially writing the sorted target data into an empty queue, keeping the target data with long estimated processing time written into one side close to the head identifier, and writing the target data with short estimated processing time into one side close to the tail identifier.
The adjustment process of the head identifier and the tail identifier specifically comprises the following steps: detecting whether a queue close to the head identifier in the read queue is an empty queue or not in real time; if so, shifting the head identifier towards the read queue to place the empty queue in the write queue; detecting whether the queue close to the tail identifier in the write queue has written target data or not in real time; if so, the tail identifier is shifted toward the write queue to place the queue into which the target data has been written in the read queue.
In this embodiment, the process of establishing the ring queue specifically includes: and connecting the data structures in the FIFO storage structure end to obtain a circular queue.
In the prior art, a polling mode is generally adopted at intervals to monitor the system state, so as to judge whether the system is available, and if the intervals are set to be too short, a large number of invalid request responses are caused, and the system overhead is increased; if the interval time is set too long, the delay performance of system state monitoring is too large; regardless of how the interval time is set, it is difficult to achieve both timeliness and request response overhead saving, because these two aspects are contradictory in this interval polling approach. In addition, there is generally a lack of balancing mechanism intervention at the receiver and sender. The sending end does not have priority, and can not obtain the busy degree of the receiving end, and the sending end only manages to send data indiscriminately; the receiving end usually processes data in an FIFO manner, and as the number of docking systems increases and the number of interactive interfaces increases, the receiving end is difficult to completely process and the performance gradually decreases.

According to the method, the target data uploaded by the heterogeneous system is calculated according to the access times, the first access time and the access priority, the number of the target data received in a single batch is selected according to the number of the empty queues in the write-in queue, the target data which are not selected can be continuously sequenced in the next batch, response does not need to be carried out on each request, and the resource overhead is effectively reduced.
