Embodiment 1

[0046] Embodiment 1: as Figure 1~5 , a data collection method based on AMP, using a dual-CPU architecture, the dual-CPU architecture has a first CPU and a second CPU, wherein the first CPU is connected to the collection device group and is responsible for data collection, and the second CPU is responsible for data collection. Extraction, processing, integration and uploading; uploading refers to uploading to a server, mobile phone or host computer, etc.;

[0047] In addition, information exchange is performed between the first CPU and the second CPU through an interrupt mode and a message queue.

[0048] The first CPU loads the ucosii operating system; the second CPU loads the linux operating system.

[0049] After the first CPU is initialized, a message queue is established.

[0050] In the first CPU, if a single data collection is completed or abnormal data in the collected data needs to be fed back immediately, the first CPU triggers an external interrupt of the second CPU...

Abstract

The invention discloses a data collecting method based on AMP. According to the method, a double-CPU framework is adopted, and the double-CPU framework is provided with a first CPU and a second CPU, wherein the first CPU is connected with a collecting equipment set and in charge of data collecting, and the second CPU is in charge of extracting, processing, integrating and uploading of data; information interaction is conducted between the first CPU and the second CPU through an interrupt mode and a message queue. The data collecting method based on the AMP has the advantages that implementation is easy, and the efficiency of data collecting and transmitting is high.

Description

technical field [0001] The invention relates to an AMP-based data collection method. Background technique [0002] With the rapid development of industrialization and informationization, automation equipment is more and more widely used in industry, and data acquisition and control systems play a very important role in automation. How to collect and interact data in real time and efficiently has become an important topic to improve the degree of industrial intelligence. [0003] In scenarios that do not require high data collection or processing, chips such as STM32 are mostly used for data collection and processing; while for systems that require high data collection efficiency, ordinary chips can no longer meet the needs. Therefore, a multi-core CPU (such as ZC7020) is introduced to complete the data processing and interaction process. Multi-core CPU brings stronger parallel processing capability, higher computing density and lower clock frequency, and greatly reduces he...
