Intelligent signal collection method

Abstract

The invention discloses an intelligent signal frequency-conversion collection method which supports various communication interfaces, constructs a communication protocol library and supports an automatic loading communication protocol to realize interaction with equipment. Each equipment can be configured with different collection frequencies, and a collection task can be automatically or manually triggered. The dynamic change of the collection frequencies is realized according to the condition of signal change, and the sampling frequency is lowered when data are not changed. When an alarm and a fault occur and the data exceed a set threshold or a change rate, the data are automatically collected at high frequency. Aiming at various communication protocols of MODBUS, CDT and the like and the modes of a nested protocol, a condition judgment protocol, a plurality of continuous messages and the like, automatic adaptation and collection is carried out. Classification processing is carried out on the collected data, real-time triggering collection and revelation is carried out on alarming information, intelligent analysis is carried out on monitoring data, and intelligent processing is carried out on the classified analysis and the like of different classes of signals of single equipment and the mixed signals of a plurality of equipment.

Description

technical field [0001] The invention relates to a method for realizing intelligent collection of various equipment data, belonging to the technical field of equipment data collection. Background technique [0002] At present, the external data interfaces and data communication methods of various devices are quite different due to their different application fields. Some use serial communication, some use Ethernet communication, and some use wireless signal transmission. The content and format of data transmitted externally by each device also vary widely. To realize the data collection and storage of these devices, it is generally necessary to develop a separate system or module for a specific communication protocol of a certain device. If the application system needs to access a variety of different devices, different modules and collection strategies need to be developed For data collection or device control, there may be various corresponding data storage methods. This ...

This method has poor scalability and also brings the maintenance burden of the acquisition program

[0003] The collection program developed for a specific device is closely related to the device. With the upgrade of the device or the change of the protocol, the collection program also needs to be adjusted or replaced accordingly, which is less flexible.

[0004] On the other hand, the existing data collection methods are relatively "passive": the collection program receives the data transmitted by the device as it is according to the set collection frequency, and seldom interacts with the device according to the received data, such as changing the collection frequency, filtering redundant data, etc. remaining data, etc.

On the one hand, this collection method causes a waste of resources and a burden on system performance; on the other hand, it is difficult to capture key data in abnormal situations
