Data Acquisition
Data Acquisition, also known as Data Acquisition, is an interface that utilizes a device that collects data from outside the system and inputs it into the system. Data acquisition technology is widely referenced in various fields. For example, cameras, microphones, are all data acquisition tools.
The data being acquired is a variety of physical quantities that have been converted into electrical signals, such as temperature, water level, wind speed, pressure, etc., either analog or digital. Acquisition is generally sampling mode, that is, a certain period of time (called sampling cycle) on the same point of the data collected repeatedly. Most of the collected data are instantaneous values, but also a characteristic value in a certain period of time. Accurate data measurement is the basis of data acquisition. There are both contact and non-contact data measurement methods, and a variety of detection elements. Regardless of which methods and components, are not to affect the state of the object to be measured and the measurement environment as a prerequisite to ensure the correctness of the data. Data acquisition has a wide meaning, embracing the acquisition of continuous physical quantities in the form of the face. In computer-aided mapping, mapping, design, graphics or image digitization process can also be called data acquisition, this time is the acquisition of geometric quantities (or including physical quantities, such as gray scale) data.
In the rapid development of the Internet industry today, data acquisition has been widely Internet and distributed areas, the field of data acquisition has undergone important changes. First, the intelligent data acquisition system in distributed control applications has made great progress at home and abroad. Secondly, the number of bus-compatible data acquisition plug-ins is increasing, and the number of data acquisition systems compatible with personal computers is also increasing. Various data acquisition machines have been introduced at home and abroad, bringing data acquisition into a whole new era.
What is data acquisition
It refers to the automatic collection of non-electrical or electrical signals from sensors and other devices to be measured, such as analog and digital units to be measured, and then sent to the host computer for analysis and processing.
The data acquisition system is a combination of measurement hardware and software products based on computers or other specialized test platforms to achieve a flexible, user-defined measurement system.
An interface utilizing a device that collects data from outside the system and inputs it into the system. Data acquisition technology is widely used in various fields. For example, cameras, microphones, are all data acquisition tools.
What is the data acquisition fee
I do not know, I know that some projects, software analysis of the piece of data needed, and the data is the site of the project, when the cooperation to do software just give me the data I can analyze, but did not say that the collection, so a single do from the field of the instrumentation generated by the data through the organization of the database of this step, but also can be charged for the project, this is my project! Encountered, other data acquisition fee is not to know
Data acquisition board, what is the data acquisition board
Data acquisition board is the realization of the data acquisition (DAQ) function of the computer expansion card, you can through the USB, PXI, PCI, PCI Express, FireWire (1394), PCMCIA, ISA, pact Flash, 485, 232, Ethernet, PCMCIA, ISA, pact Flash, PCMCIA, ISA, pact Flash, 485, 232, Pact Flash, Pact Flash, PCMCIA, ISA, pact Flash, pact Flash, pact Flash, pact Flash. PXI, PCI Express, FireWire (1394), PCMCIA, ISA, pact Flash, 485, 232, Ethernet, various wireless networks and other buses to access the personal computer.
The vast majority of data acquisition boards are focused on the collection of analog, digital, RTD, thermocouple, where RTD can be considered non-electricity (in fact, essentially still to use the current driver to collect) data acquisition software (infinityqs) which analog acquisition card and digital acquisition card is the most widely used. Now there is a two-in-one acquisition card on the market, two-in-one refers to the digital-analog acquisition card, AV + DV acquisition card, digital, analog two-in-one, digital input and output, analog interface input (DV/AV/S-video).
The data acquisition board in the actual application often need it to output control signals. Data acquisition cards are widely used in security monitoring, education courseware recording, large screen splicing, multimedia recording video, conference recording, virtual studio, virtual reality, security X-ray machine, radar image signal, VDR recorder, medical X-ray machine, CT machine, gastrointestinal machine, *** mirrors, industrial inspection, intelligent transportation, medical imaging, industrial monitoring, instrumentation, machine vision and other fields.

What does the data collector do
The data collector is mainly responsible for the entry and verification of basic information (including pre-basic data and various documents) in the ERP system (Enterprise Resource Planning "Enterprise Resource Planning" for short).
A data collector's main work is as follows:
1, will use the capture data software to capture resources from the Internet and distribution;
2, from the Internet to collect information on educational enterprises;
3, the collection of information for the record and classification statistics;
4, the company provides a variety of information for the information to be updated and improved;
5, the collection of shopping mall store number, store name and the main type of business;
6, to participate in the company's professional website daily information collection, entry, publishing, writing, etc.;
7, to complete the leadership of the other work tasks.
Second, the data collector job requirements:
1, age 21-35 years old;
2, can bear hardships and stand hard work, love of tourism, conscientious and responsible, with a positive attitude towards work, the face of pressure can have a good attitude;
3, with normal interpersonal communication skills, lively and down-to-earth personality, driving license will drive is preferred;
4, Have good writing editing skills is preferred.
What is web data collection, what is it for, and how is it accomplished? 10 points
Web page data collection: simply said to get some of the data on the web page of their own interest. The current big data is quite hot, so there are very many collection software on the network, the role of data collection has a variety of uses, the more commonly used is: 1.
