Embodiment 1

[0046] Data conversion system for data acquisition instrument, including data acquisition terminal, analysis table configuration module, data conversion module and upper computer,

[0047] The data collection terminal is used to collect data information, sends the data information to the data conversion module, and sends the device information to the analysis table configuration module, and the device information includes the serial number of the collection device used; in this embodiment, the data collection terminal includes the basic observation elements Sensors, basic observation elements Sensors include temperature sensors, humidity sensors, air pressure sensors, wind speed sensors, wind speed sensors, wind direction sensors and rain sensors; and interfaces for external sensors or devices are provided for connecting users to sensors for collecting data information Or equipment, specifically, when the sensors provided by the system do not meet the user's needs, the user can...

Embodiment 2

[0070] It is used in the data conversion system of the data acquisition instrument, and the difference from the first embodiment is that, as figure 1 As shown, it also includes a fault diagnosis module, which is used to detect the current signal and voltage signal of the data acquisition terminal. When the current signal and voltage signal do not change within a preset period of time, it is judged that the data acquisition terminal is faulty and sent to the host computer. Alarm signal; when the current signal and voltage signal change within a preset period of time, it is judged that the data acquisition terminal is normal, and an instruction for manually configuring the sub-analysis table is sent to the analysis table configuration module.

Embodiment 3

[0072] Used in the data acquisition instrument data conversion system, the difference from Embodiment 1 is that the analysis table configuration module is also used to record the service life and cumulative use time of the basic element sensors and external sensors or equipment connected in the data acquisition terminal, It is also used to mark it as a monitoring device when the accumulative use time of the basic element sensor, or external sensor or equipment reaches the preset time limit. In this embodiment, the preset time limit is 10 days before the service life. In other embodiments According to the error between the actual service life of the device and the service life marked on the device, the expected period can be adjusted back and forth accordingly. Analyze the configuration table module and generate external device information according to the model of the monitoring device, and send it to the host computer. The user obtains the external device information through ...

Abstract

The invention relates to the field of data acquisition, and particularly discloses a data conversion system for a data acquisition instrument, which comprises a data acquisition terminal, an analysistable configuration module, a data conversion module and an upper computer, the data acquisition terminal is used for acquiring data information, sending the data information to the data conversion module and sending equipment information to the analysis table configuration module; the analysis table configuration module is used for identifying equipment information and sending an analysis table;the upper computer is used for inputting analysis data according to the original analysis table and the equipment information to generate a sub-analysis table; and the data conversion module is used for identifying and converting the data information according to the sub-analysis table to obtain detection data, and sending the detection data to the upper computer. The invention further provides adata conversion method for the data acquisition instrument. According to the scheme, new sensors or equipment can be expanded without redeveloping a data acquisition system, and the adaptability of the data acquisition system is improved, so that the data acquisition cost is reduced.

Description

technical field [0001] The invention relates to the field of data acquisition, in particular to a data conversion system and method for a data acquisition instrument. Background technique [0002] The data acquisition instrument is used to collect and store the data of various types of testing instruments and meters, complete the data transmission function with the host computer, and also have a separate data processing function. The data acquisition instrument is an important part of the data acquisition system. Currently, a large number of data acquisition systems are generally based on a data collector with a microcomputer as the core, and various output signal sensors are connected to the data collector in the form of wires, and the data collector performs data collection. Conversion acquisition processing; for large-scale automatic data acquisition systems, due to the wide variety of sensors, when the data information collected by the sensors is transmitted to the data...
