Multifunctional data acquisition unit and data acquisition method thereof

Abstract

The invention relates to a multifunctional data acquisition unit. The multifunctional data acquisition unit comprises at least one data acquisition terminal and a data processor in both-way communication connection with the data acquisition terminals. The data processor comprises a device driver module used for bearing drivers of all the data acquisition terminals. The multifunctional data acquisition unit further comprises a multiplexer, wherein the multiplexer is in both-way communication with the data acquisition terminals and the data processor respectively. The data acquisition terminals are used for acquiring data and transmitting the data to the data processor; the multiplexer is used for recognizing the types of the data acquisition terminals having access to the data acquisition unit; the data processor is used for converting the format of the received data into a USB data package format according to the types of the data acquisition terminals. The multifunctional data acquisition unit is diversified in function and compatible with various data acquisition peripherals and saves cost.

Description

technical field [0001] The invention relates to a data collector and a data collection method thereof, more specifically to a multifunctional data collector and a data collection method thereof. Background technique [0002] In the on-site operation field of electric power enterprises, safe mobile operation terminals are indispensable equipment. Hand-held terminals used in the industrial field are collectively referred to as industrial-grade PDAs. It is a PDA that can be applied in various industrial environments. Due to the harsh industrial environment, For example: high temperature, dust, etc. Therefore, industrial-grade PDAs generally must reach a certain industrial grade, have a wear-resistant shell, and are dustproof, waterproof, and drop-proof. There are many types of industrial PDA equipment, such as barcode scanners, RFID readers, POS machines, etc. The characteristics of different devices are different, and the interface methods adopted by different devices are als...

AI Technical Summary

Problems solved by technology

Traditional industrial-grade PDAs are only responsible for the work in a specific field, and their compatibility and scalability are poor. For example, barcode scanning is only responsible for scanning barcodes; traditional data interfaces are only responsible for connecting one type of equipment, such as serial ports. equipment

[0003] All of the above conditions limit the expansion and compatibility of the interface. It can only be used for a single device. When it is compatible and connected to a new device, a lot of modification work on the existing interface is required, and even a new interface is developed. However, the actual The business functions will not increase, which will cause waste of original functions and consume huge workload and cost
