[0143] Embodiment 8:

[0144] The embodiment of the present invention provides a method for implementing a multi-source concurrent data acquisition device at an industrial site, setting key acquisition indicator data of acquired business data and setting acquisition evaluation indicators of a multi-core main control platform, including:

[0145] Setting key indicator data for collecting business data and setting collection evaluation indicators for the multi-core main control platform, when the multi-core main control platform monitors the key indicator data for collection, it determines that the corresponding collected business data is effectively collected;

[0146] Otherwise, determining that the corresponding collected service data is a collection exception, locating and retransmitting the corresponding collected service data;

[0147] A current collection evaluation value of corresponding collected business data is obtained. When the current collection evaluation value exceeds the collection evaluation index range, the corresponding collected business data is determined to be a second-class collection anomaly, and the corresponding collected business data is located and retransmitted.

[0148] In this embodiment, key indicator data for collecting business data is set, for example, key indicator data a1 is collected. When the multi-core main control platform monitors the key indicator data a1, it determines that the corresponding business data is collected effectively and the corresponding industrial site multi-source concurrent data collection equipment is working normally.

[0149] In this embodiment, one type of acquisition anomaly refers to an acquisition anomaly caused by a device anomaly.

[0150] In this embodiment, obtaining the current collection evaluation value of the corresponding collection service data refers to a value determined by evaluating and quantifying the collection evaluation index of the set multi-core main control platform.

[0151] In this embodiment, when the current collection evaluation value exceeds the collection evaluation index range, it is determined that the corresponding collection business data has a second-class collection anomaly, that is, data collection anomaly, for example, collection accuracy anomaly.

[0152] The working principle and beneficial effect of the above technical solution are: by setting the key indicator data for collecting business data and setting the collection evaluation indicators of the multi-core main control platform, it is helpful to ensure the real-time collection of key indicator data and accurately perceive collection anomalies.

[0153] Embodiment 9:

[0154] The embodiment of the present invention provides a method for implementing a multi-source concurrent data acquisition device at an industrial site, which performs data caching and storage on the collected service data collected in parallel according to a circular cache queue, including:

[0155] A buffer is built into the data processor of the multi-core main control platform. When the buffer is full of a preset number of bytes of collected business data, a high-level interrupt is generated. A memory area is opened in the large-capacity memory based on the kernel for use as a circular buffer queue.

[0156] When the ring buffer queue is created, data movement is started in the data processor according to the preset bus reading method, and the data in the buffer is migrated to the large-capacity memory;

[0157] When the data migration is completed, the main core processor queries the working status of other processors through an independent working thread, and notifies the corresponding processor to fetch the temporary data from the base address of the memory pointer through an internal interrupt, and then waits for the next buffer interrupt. When the next buffer interrupt arrives, the data is cyclically stored in the address of the memory base address;

[0158] When the main core processor receives an interrupt, it confirms the current time point in the corresponding memory, creates a new file with the current timestamp as the mark, and writes the collected business data;

[0159] When the monitoring receives an interrupt from the main core processor, the data in the memory bar queue is cyclically stored in the file, so that the data collected in parallel is cached and stored according to the circular cache queue.

[0160] In this embodiment, the high-level interrupt is used by the kernel to allocate a memory area in the large-capacity memory.

[0161] In this embodiment, the ring cache queue refers to a memory area allocated by the kernel in the large-capacity memory.

[0162] In this embodiment, a bus reading mode is preset, for example, a point-to-point bus reading mode.

[0163] In this embodiment, data migration refers to migrating data in the buffer to a large-capacity memory to achieve high-speed data storage.

[0164] In this embodiment, the main core processor queries the working status of other processors through an independent working thread, and notifies the corresponding processor to fetch temporary data from the base address of the memory bar pointer through an internal interrupt, and then waits for the next cache interrupt. After the next cache interrupt arrives, the data is cyclically stored in the address of the memory base address. For example, when the main core processor a1 queries through an independent working thread that other processor b1 is in a normal standby working state, it notifies processor b1 to fetch temporary data from the base address of the memory bar pointer, and then waits for the next cache interrupt. After the next cache interrupt arrives, the data is cyclically stored in the address of the memory base address.

[0165] In this embodiment, other processor working states include, for example, a normal standby working state, a normal running working state, an abnormal standby working state, and an abnormal running working state.

[0166] In this embodiment, the memory base address is the memory bank pointer base address.

[0167] In this embodiment, an internal interrupt, that is, a high-level interrupt is generated after the buffer is fully stored with a preset number of bytes of collected service data.

[0168] In this embodiment, if Figure 4 , 5 As shown, when the buffer is full of the preset number of bytes of collected business data, a high-level interrupt is generated, which enables the core CPU0 to open a memory area in the DDR4 memory for use as a circular cache queue. After the core CPU0 queue is opened, data movement is started from the FPGA in the PCIE X4 bus reading mode to migrate the data in the FIFO buffer to the DDR memory.

[0169] The working principle and beneficial effect of the above technical solution are: by caching and storing the collected business data collected in parallel according to the circular cache queue, high-speed storage of the collected business data is effectively achieved.

[0170] Embodiment 10:

[0171] An embodiment of the present invention provides a method for implementing an industrial site multi-source concurrent data acquisition device, further comprising:

[0172] When the main core processor is waiting for the buffer interrupt, the buffer data in the memory bar queue is sent to the host computer via Gigabit Ethernet;

[0173] When the acquisition is completed, the files stored in the high-speed memory are queried, deleted and downloaded through the host computer.

[0174] In this embodiment, the memory bank queue is a circular buffer queue in the memory bank.

[0175] In this embodiment, the host computer refers to a device for users to query, delete and download stored files.

[0176] The working principle and beneficial effect of the above technical solution are: by sending the cached data in the memory bar queue to the host computer through Gigabit Ethernet, high-speed reading of collected business data is effectively achieved, which is beneficial for users to access and utilize cached data.
