[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Example 1 As the technical problem mentioned in the background technology, this application proposes a data storage method based on a circular queue, such as Figure 1 As shown, the following steps are included: S100. Configuring an array queue in the control processing unit, the array queue comprises multiple queues, each queue has a unique queue address, and the queue is used to store telemetry data sent from the information processing system; Among them, this method is executed on the control and management processing unit of the infrared guidance head, the input end of the control and management processing unit is connected to the output end of the information processing system, and is used to receive the telemetry data sent by the information processing system with a certain time period; the output end of the control and management unit is connected to the input end of the integrated control machine, and the integrated control machine reads the data of the control and management processing unit with the same time period.

[0020] First, the array queue is initialized, the number of queues and the size of data that can be stored in each queue are set, wherein the size of data that can be stored in the queue depends on the telemetry data. For example, if the telemetry data received each time is 64 bytes, the capacity of the queue is set to 64 bytes, that is, it can store one telemetry data; and the number of bytes that the queue pointer jumps each time is the same as the size of data stored in each queue, that is, the queue pointer jumps 64 bytes each time and jumps to the position of the next queue.

[0021] S200. Receive telemetry data and obtain the number of receptions and transmissions; The control processing unit includes a first counting unit and a second counting unit. The first counting unit is used to record the number of times the telemetry data has been received, and the second counting unit is used to record the number of times the telemetry data has been sent.

[0022] Before step S300 and after step S200, the following steps are also included: S210. Determine whether the array queue is full, and obtain a first determination result or a second determination result, wherein the first determination result is that the array queue is not full, and the second determination result is that the array queue is full; comprising the following steps: S211. Obtain the maximum capacity of the array queue, the size of data that can be stored in each queue, and the difference between the number of receptions and the number of transmissions, recorded as the first difference; Among them, according to the number of queues and the capacity of each queue, the maximum capacity of the entire array queue can be obtained. For example, the data size that each queue can store is 64 bytes, and if there are 10 queues, the maximum capacity is 640 bytes.

[0023] S212. Calculate the occupied capacity based on the first difference and the data size; The occupied capacity is obtained by multiplying the first difference and the data size. For example, if the first difference is 2, the occupied capacity is 2*64=128.

[0024] S213. Determine the size of the occupied capacity and the maximum capacity. When the occupied capacity is smaller than the maximum capacity, the first determination result is obtained; when the occupied capacity is greater than or equal to the maximum capacity, the second determination result is obtained.

[0025] S220. In response to the first judgment result, continue to execute steps S300-S600.

[0026] Among them, taking the first difference value of 2 as an example, the occupied capacity is 128, which is less than 640, and there is still some space left in the array queue for storing the telemetry data, so continue to execute the subsequent steps.

[0027] S230. In response to the second judgment result, stop receiving the telemetry data.

[0028] When the communication between the control and management processing unit of the infrared guidance head and the integrated control machine is interrupted, but the communication with the information processing system is good, the control and management processing unit always receives the telemetry data periodically sent by the information processing system, but the integrated control machine cannot read data from the control and management processing unit, so that the array queue is full and no longer receives telemetry data; therefore, this can avoid the problem of data overflow caused by the control and management processing unit thinking that it is continuously receiving telemetry data sent by the information processing system when the communication between the integrated control machine and the control and management processing unit is interrupted, thereby causing program running errors.

[0029] S300. Calculate the receiving queue address according to the number of receptions; For example, there are ten queues, including the first queue, the second queue...the tenth queue, and the storage order is from one to ten. The queue pointer includes a storage pointer and a read pointer. The storage pointer first points to the first queue. When the tenth queue stores data, since the order of reading data is the same as the storage, both start from the first queue. When the occupied capacity is less than the maximum capacity, at least the first queue does not store data, and the received eleventh telemetry data is stored in the first queue for circular storage; therefore, the specified queue can be obtained by the number of receptions and the number of queues, and then the address of the queue is obtained, which is the receiving queue address. Each time a telemetry data is stored, the storage pointer jumps to the next queue position, and the address of the queue pointed to by the storage pointer is the receiving queue address.

[0030] S400. Obtain the queue with the same queue address as the receiving queue address, record it as the receiving queue, store the telemetry data in the receiving queue, and increase the number of receptions by one; The telemetry data is stored in the queue, the number of receptions is increased by one, and the storage pointer jumps to the next queue.

[0031] Before step S500 and after step S400, the following steps are also included: S410. Determine whether the array queue is empty, and obtain a third determination result or a fourth determination result, wherein the third determination result is that the array queue is empty, and the fourth determination result is that the array queue is not empty; comprising the following steps: S411. Compare the number of receptions and the number of transmissions. If the number of receptions is greater than the number of transmissions, obtain the fourth judgment result. If the number of receptions is less than or equal to the number of transmissions, obtain the third judgment result.

[0032] S420. In response to the fourth judgment result, continue to execute steps S500-S600.

[0033] That is, the control unit receives more data than the sent data, so the array queue is not empty and the telemetry data is still stored, so the reading operation continues, that is, the subsequent steps continue.

[0034] S500. Calculate the sending queue address according to the number of sending times; The order of reading data from the array queue is the same as the order of storing data. Taking the first to tenth queues as an example, the first queue at the head of the queue is read first, and the read pointer first points to the first queue. Each time a data is read out, the read pointer jumps to the next queue, and the queue address is the sending queue address. S600. Obtain the queue whose queue address is the same as the sending queue address, record it as the sending queue, send the telemetry data stored in the sending queue to the integrated control machine, and increase the number of sending times by one. It includes the following steps: S610. Send the telemetry data in the sending queue to a data buffer; Optionally, the present application adopts a 1553B bus for data communication, and the 1553B system has a data buffer for avoiding data loss.

[0035] S620. Sending the telemetry data in the data buffer to the integrated control machine; In summary, this application can avoid jitter when the integrated control machine reads telemetry data. Although the information processing system, infrared seeker control processing unit and integrated control machine have the same time period, the communication is not synchronized, which makes the reading time lag or advance, resulting in reading two data or data loss. By storing data in an array queue, it is ensured that the integrated control machine can stably obtain correct telemetry data within the reading cycle.
