How to collect data on the spot?

For most manufacturing enterprises, the automatic data acquisition of measuring instruments has always been a troublesome thing, even if the instrument has RS232 485 and other interfaces, but still in the use of measurement, while manually recording to the paper, and finally input into the PC to process the way, not only the work is heavy, but also can not ensure the accuracy of the data, often the data obtained by the management personnel has been lagging behind the data for a day or two; For on-site defective product information and related output data, how to achieve efficient, concise and real-time data collection is a major problem.

The four common methods of data collection include questionnaire surveys, data review, field investigations, and experiments, and each of these methods has its own disadvantages and disadvantages, which are analyzed as follows.

The first is a questionnaire. Surveys are the most common method of data collection because they are less expensive and more comprehensive. However, the answers obtained from the questionnaire are often untargeted, which means that the data collected by the questionnaire needs to be further analyzed.

In addition, in the past, the promotion of questionnaires would be slower because it was very labor-intensive. But now there are a lot of questionnaires on the Internet**, and if you collect data through questionnaires**, it will be more convenient and faster. Therefore, the questionnaire survey is easy to operate, but the disadvantage is that the data is not targeted and cannot get in-depth data.

The second is to consult information. Consulting is the oldest way of data collection, by consulting books, records, etc., to get the data you want. In this data collection process, there is an inherently filtering and analytical nature, which means that the data obtained from the data may be relatively close to the results you want.

Nowadays, whether it is a library or an Internet query, it is very convenient, and it provides a good environment for consulting materials. The disadvantage of consulting the data is that the requirements for the operator are very high, and the current data is cumbersome, and the truth is mixed, which requires a high degree of judgment.

The third is on-site inspection. A field trip is to go to a designated place to do research. It refers to the fact that in order to understand the truth of a thing and the development process of the situation, we go to the field to conduct an intuitive and partial detailed investigation.

In the course of the investigation, it is necessary to analyze the phenomena observed by oneself at any time and strive to grasp the characteristics of the object of investigation. This method of collecting data is time-consuming, labor-intensive, and requires everyone's cooperation. The advantage of this method of collection is that you can get first-hand information in the first place, and the disadvantage is that you may not be able to achieve the goal you want, because there are also a lot of variables in the process of investigation.

Fourth, experiments. Experimental design data is the most time-consuming of the four methodsBecause it is through a variety of experiments to get a unified direction, that is, in the process, there can be countless failures. But the data from the experiment is the most accurate, and it may drive progress in a certain industry.

So,The advantage of experimental data collection is that the accuracy of the data is high, while the disadvantage is that it is highly unknown, and both the period of the experiment and the results of the experiment are uncertain.

With the development of technology and the advent of the era of big data, it is becoming easier and easier to collect data, and everyone should pay more attention to protecting and using data.

Data acquisition refers to the automatic collection of non-electric or electric signals from analog and digital units under test such as sensors and other devices under test, and sending them to the host computer for analysis and processing. The data acquisition system is a combination of measurement software and hardware products based on computers or other dedicated test platforms to achieve a flexible, user-defined measurement system.

Data acquisition, also known as data acquisition, is an interface that uses a device to collect data from outside the system and input it into the system. Data acquisition technology is widely used in various fields. For example, cameras and microphones are all data collection tools.

The collected data is a variety of physical quantities that have been converted into telecommunication signals, such as temperature, water level, wind speed, pressure, etc., which can be analog or digital. The collection is generally a sampling method, that is, the same point of data is repeatedly collected at certain intervals (called sampling periods). Most of the collected data is instantaneous, but it can also be a characteristic value over a certain period of time.

Accurate data measurement is the basis of data acquisition. There are contact and non-contact data measurement methods, and there are various detection components. Regardless of the method and component, the accuracy of the data is guaranteed on the premise that the state of the measured object and the measurement environment are not affected.

Data acquisition has a wide range of meanings, including the acquisition of continuous physical quantities in the form of surfaces. In computer-aided drawing, mapping, and design, the process of digitizing graphics or images can also be called data acquisition, where geometric quantities (or physical quantities, such as grayscale) data are collected.

Data collection refers to the process of collecting, processing, and preserving data to transform data into information that can be used for analysis and decision-making. In today's digital age, data collection has become an important step in business operations and decision-making. Through data collection, companies can understand the details and trends of their core business to better complete business operations and optimization.

Data collection is fundamental to the business conduct of MES MES, and it is also the basis for statistical analysis of MES MES. In the application of MES manufacturing execution system software, different data collection methods and different data collection equipment need to be selected according to different factors such as data, application posture scenarios, personnel capabilities, equipment investment, etc. According to the classification of various types of data, different data collection methods are adopted.

Below, a brief introduction to several common types of data collection methods.

First: the data that must be entered;

The second is: the data automatically generated by the system;

The third is: through the way of barcode collection;

Fourth: sensor collection data;

Fifth: RFID data collection.
