Example 1
Fig. 1 is a flowchart of a method for detecting industrial information based on a shared memory according to an embodiment of the present invention, where the method may be performed by an industrial information detecting device based on a shared memory, the industrial information detecting device may be implemented in a form of hardware and/or software, and the industrial information detecting device may be integrally configured in an electronic device. As shown in fig. 1, the method includes:
step S101, loading the shared memory based on the shared memory configuration file and the memory management component so that the front end and the back end have the authority to read and write the shared memory.
Optionally, before loading the shared memory based on the shared memory configuration file and the memory management component, the method further includes: receiving a shared memory configuration file preset by a user, wherein the shared memory configuration file comprises shared memory creation parameters, and the shared memory creation parameters comprise: shared memory name, shared memory size, number of cache areas contained in each shared memory, and maximum length requirement of information stored in the cache areas; and storing the shared memory configuration file locally according to a specified path, and creating a memory management component associated with the shared memory, wherein the memory management component comprises a shared memory function loading interface, an industrial information function interface to be detected placed in the front end, an industrial information function interface to be detected acquired by the rear end, a rear-end return rear-end message function interface and a rear-end message function interface acquired by the front end.
Specifically, in this embodiment, the front end for receiving the industrial information to be detected and the back end for processing the industrial information to be detected are both located on the same terminal device, so that in order to increase the speed of data transmission between the front end and the back end, the shared memory with a specified number and size can be allocated on the terminal device according to the requirement, and the front end and the back end can quickly perform information interaction based on the shared memory. Before loading the shared memory on the terminal device, the terminal device receives a shared memory configuration file preset by a user, and the shared memory configuration file includes shared memory creation parameters, where the following codes are examples of the shared memory configuration file:
"shm1":{
"max_image_width": 2000,
"max_image_height": 1000,
"max_image_channel": 3,
"buff_nums": 5,
"comm_bytes_length": 10485760,
}
wherein, shm1 is the name of the shared memory, max_image_width is the maximum picture width that may occur in the section of shared memory, max_image_height is the maximum picture height that may occur in the section of shared memory, and max_image_channel is the maximum number of channels of pictures that may occur in the section of shared memory;
the buff_num is the size that needs several buffers in the segment of shared memory, and comm_bytes_length is the size reserved for the message passing area in a single buffer, in bytes, typically 10485760 bytes = 10MB size is recommended. The shared memory names in the shared memory configuration file should have uniqueness on the host, because a plurality of shared memories can be created at the same time, when the subsequent front end and the back end perform message interaction through the shared memories, which shared memory is used can be determined according to the shared memory names with uniqueness, so as to avoid confusion of interaction information.
It should be noted that, after the terminal device obtains the shared memory configuration file, the terminal device will save the shared memory configuration file locally according to the designated path, and create a memory management component associated with the shared memory, where the memory management component includes loading the shared memory function interface, placing the front end into the industrial information function interface to be detected, obtaining the industrial information function interface to be detected by the back end, returning the back end to the back end message function interface, and obtaining the back end message function interface by the front end. The loading shared memory function interface is loadConfigFromFile, and the code definition form is as follows: void loadConfigFromFile (const char) is specifically used to obtain shared memory information from the shared memory configuration file into the process, such as shared memory name, shared memory pre-allocation size, shared memory pointer information, etc., where fileName refers to the existence of a locally stored specified path in the shared memory. The front end is put into an industrial information function interface to be detected to be a putImgAndMsgByMat, and the code definition form is as follows: returnFrontPut putImgAndMsgByMat (const unsigned char pData, unsiged long long width, unsiged long long height, unsiged long long channel, const char shmName, int buffid=0, const char tag=null, void message=null, int messageLength =0, int message type=message type:: string) is specifically implemented by placing picture data and messages into a buffer in a manner of decoding data in a one-dimensional picture memory. The back end obtains the industrial information function interface to be detected as getImgAndMsg, and the code definition form is as follows: returnBackGet getImgAndMsg (const char. ShmName, int buffid=0), specifically to obtain the detection industrial information sent by the front end from the buffer. The back-end return back-end message function interface is putMsg, and the code definition form is: the specific effect of the void putMsg (const char, int buffId, void message=null, int messageLength =0, int message type=message type:: string) is to place the backend message into a designated buffer, and then receive the backend message from the front end. The front-end acquired back-end message function interface is getMsg, and the code definition form is: returnFrontGet getMsg (const char. ShmName, int buffid=0), specifically, a message returned after the back-end processes the picture is obtained from the buffer. Of course, the function interfaces included in the memory management component are only illustrated in the present embodiment, and the specific types of the function interfaces in the memory management component are not limited.
Optionally, loading the shared memory based on the shared memory configuration file and the memory management component includes: the front end or the back end calls a shared memory function loading interface in the memory management assembly; reading shared memory creation parameters in a shared memory configuration file from a designated path through loading a shared memory function interface; and loading the shared memory with the specified quantity and the specified size locally according to the shared memory creation parameters.
It should be noted that, in this embodiment, the shared memory may be created by a front end or may be created by a back end, and specifically, the creation main body of the shared memory is determined according to the starting time, for example, when the front end starts first, the front end calls a loadConfigFromFile of a loadshared memory function interface, reads a shared memory configuration file from a specified path through the loadshared memory function interface, obtains shared memory creation parameters in the shared memory configuration file, and locally loads a specified number and a specified size of the shared memory according to the shared memory creation parameters, for example, creates a shared memory named as shm1, the number of buffers is 5, the maximum picture width possible to occur in the shared memory is 2000, the maximum picture height possible to occur in the shared memory is 1000, the maximum channel number possible to occur in the shared memory is 3, and the reserved size of a passive message transfer area in each buffer is 10485760 bytes.
It should be noted that, since the shared memory configuration One configuration will coordinate to apply several named shared memories One Share to the system, and several buffer areas are divided in each shared memory, as shown in fig. 2, when One Share of shared memories including 5 buffer areas needs to be applied, each buffer Area includes three parts of Block Header information Block Header, picture storage Area Image buffer and passive message transfer Area Comm Area, the picture storage Area is used for storing an Image to be detected in the industrial information to be detected, the passive message transfer Area is used for storing interactive information of front end and rear end, and the Block Header message Block Header includes Block status code status, type tag of the Image to be detected, real height readheight ty, real width realdth, real channel realChannel, message type message of front end message in the industrial information to be detected and message length message. The tag is set by the front-end write buffer area, namely the buff area, so as to inform the back-end of the necessary parameter information of the picture; the realWidth is the real width of the picture, and is set by the front end writing the target buffer area, so that the rear end can understand the real data of the one-dimensional picture in the memory into a picture tensor form; the realignment is the real high of the picture, and is set by the front end writing the target buffer area, so that the rear end can understand the real data of the one-dimensional picture in the memory into a picture tensor form; the realChannel is a real channel of the picture, and is set by the front end writing the target buffer area, so that the rear end can understand real data of the one-dimensional picture in the memory into a picture tensor form; the messageType is a message type, and is set when the front end sends a message or replies to the message, such as String (0) and Json (1); the message length is the message length, and is set when the front end sends the message or the back end replies to the message. The block code blockstatus comprises three states, namely: front go represents the information returned by the back-end that the front-end has taken. Marking the end of a round of information exchange, which also means that the buff area returns to the initial state; front end represents that the front end finishes writing information into the cache area; the backover represents that the back end finishes processing the information in the buffer area and returns a corresponding result, namely finishing writing the information.
Step S102, when the front end receives the industrial information to be detected, the industrial information to be detected is saved into the shared memory by calling the memory management component.
Optionally, the storing the industrial information to be detected in the shared memory by calling the memory management component includes: determining a target cache region in the shared memory by calling the front end of the memory management component to put into an industrial information function interface to be detected; storing the image to be detected in the industrial information to be detected in a picture storage area of a target cache area, and storing the front-end message in the industrial information to be detected in a passive message transmission area of the target cache area; storing the type label, the real height, the real width, the real channel, the message type and the message length of the front-end message of the detected image into the block header information of the target cache area; and updating the block status code in the block header information into a front-end information writing completion status through the memory management component.
Specifically, in the process of an industrial defect detection project, the front end simultaneously collects color pictures with the width of 2000 and the height of 1000 from five cameras each time, transmits the color pictures to the rear end for detection, and sequentially calls or multithreads call the front end of the memory management component to be placed into an industrial information function interface to be detected to determine a target cache region in the shared memory after the front end receives the five pictures from the cameras. When the rear end has only one model, in this embodiment, an idle buffer area may be arbitrarily selected from the five buffer areas as a target buffer area, and when the rear end has a plurality of different models to process images, the front end may establish a correspondence between the camera and the buffer area in advance, for example, an image collected by the camera 1 is stored in the buffer area 1, an image collected by the camera 2 is stored in the buffer area 2. Of course, this embodiment is merely illustrative, and the specific determination mode of the target buffer area is not limited.
After determining the target buffer area, for example, buff1, the to-be-detected industrial information includes the to-be-detected image and the front message, and the front message specifically includes a specific processing mode for the to-be-detected image, so that the front end stores the to-be-detected image in a picture storage area of the target buffer area, stores the front message in a passive message transmission area of the target buffer area, and places the picture and the message into the shared memory and waits for the rear end to read. Meanwhile, the front end also stores the associated information of the picture and the message into the block header information of the target cache area, for example, the type label, the real height, the real width, the real channel and other related information of the picture or the message, and when the associated information is determined not to meet the storage format requirement of the shared memory, the storage of the picture or the message in the target cache area is stopped, for example, when the maximum width of the picture stored in the cache area is 2000, but the maximum width of the picture obtained from the camera is 5000, and because 5000 exceeds the maximum bearing capacity of the shared memory, the storage process of the picture is stopped.
It should be noted that, since the block header message includes the block status code, the memory management component updates the status code, and the API in front-end and back-end communication ensures that the events are executed in the correct order by polling the status code, when determining that the front-end writes the picture and the message into the target buffer area, the memory management component updates the block status code into the front-end writing information finishing status, i.e. front-end.
Step S103, the back end directly reads the industrial information to be detected from the shared memory by calling the memory management component, and stores the back end information generated by detecting the industrial information to be detected into the shared memory.
Optionally, the back-end directly reads the industrial information to be detected from the shared memory by calling the memory management component, and stores a back-end message generated by detecting the industrial information to be detected into the shared memory, including: the back end reads the image to be detected from the picture storage area of the target cache area by calling the back end in the memory management assembly to acquire the industrial information function interface to be detected, and reads the front-end message from the passive message transmission area; reading an image detection processing mode from the front-end message, and carrying out detection processing on an image to be detected according to the image detection processing mode to generate a back-end message; the back end returns back end message function interface to store back end message into passive message transfer area of target buffer area by calling back end in memory management assembly; and updating the block status code in the block header information into a rear-end information writing completion status through the memory management component.
Specifically, the back end in this embodiment performs periodic event polling, so when the back end determines that the front end has written information through reading the block status code, the back end in the memory management component is called to obtain the industrial information function interface getimgcandmsg to be detected, the images to be detected are respectively read from the image storage area of the target buffer area, the front end message is read from the passive message transmission area, and the images to be detected are detected according to the image detection processing mode in the front end message to generate the back end message, and the industrial information detection result, for example, the parts in the image are determined to be undamaged as qualified products in the back end message. And the back end can call a back end return back end message function interface putMsg in the memory management component to store the back end message in a passive message transfer area of the target cache area, namely, the industrial information to be detected of the back end is read from the cache area buff1, and the corresponding back end message of the processing result aiming at the industrial information to be detected can be stored in the cache area buff1 continuously.
It should be noted that, the memory management component is responsible for updating the status code blockstatus, and when determining that the back end stores the processing result of the industrial information to be detected, that is, the back end message, in the target cache area, the memory management component updates the block status code to a back end information writing completion status, that is, back over.
In step S104, the front end reads the back end message in the shared memory by calling the memory management component to obtain the industrial information detection result.
Optionally, the front end reads the back end message in the shared memory by calling the memory management component, including: the front end acquires the back end message from the passive message transfer area of the target cache area by calling a front end acquisition back end message function interface in the memory management assembly, and takes the back end message as an industrial target detection result; and updating the block status code in the block header information to the front end read information through the memory management component.
Specifically, the front end in this embodiment also performs periodic event polling, and when the front end determines that the back end has written information by reading the block status code, the front end in the memory management component is called to acquire the back end message function interface getMsg, acquire the back end message from the target cache area, and use the back end message as an industrial information detection result, and similarly to the back end, when the front end stores the industrial information to be detected in the buff1, the front end correspondingly reads the back end message from the buff 1. At this time, the memory management component updates the block status code to the information status returned by the front-end after the front-end has been taken out, i.e. frontgo.

And the front end only needs to copy the picture data to the shared memory directly through an application program interface (Application Programming Interface, API), and the back end only needs to read the shared memory without additional data copying, thus completing the whole information exchange flow. This approach, which approximates the way local program memory is operated, is compact and efficient. In addition, because the IO speed of the memory is significantly superior to that of the hard disk and the network interface, extremely low latency is achieved by using the shared memory as a connection between different programs. Meanwhile, due to the high capacity characteristic of the shared memory, the encoding and decoding and queue transmission processes of the data are greatly reduced, and the stability and consistency of the data are further enhanced. The programming mode of the embodiment is prone to traditional functional programming, and the program interface can be built by simply calling a plurality of APIs. This approach reduces the complexity of network programming so that developers can concentrate on business logic processing without undue attention to network configuration and optimization.
According to the embodiment of the invention, the shared memory is created to provide a way for front-end and back-end communication, the front end only needs to store the industrial information to be detected into the shared memory through the calling interface, the back end does not need to copy additional data, and the whole information interaction process can be completed only by reading the shared memory, so that the data transmission speed is improved, the redundancy in the data transmission process is reduced, and the accuracy of target detection is improved.
