What Is a Smartphone Data Plan?

Data acquisition (DAQ) refers to the automatic collection of non-electricity or electrical signals from analog and digital units under test such as sensors and other equipment under test, and sends them to the upper computer for analysis and processing. The data acquisition system is a flexible, user-defined measurement system combined with measurement software and hardware products based on computers or other special test platforms.

Data collection

Intelligent manufacturing is inseparable from the support of workshop production data. In the manufacturing process, CNC machine tools are not only production tools and equipment, but also nodes of the workshop information network. The automatic collection, statistics, analysis and feedback of machine tool data will be used to improve the manufacturing process, which will greatly improve the flexibility of the manufacturing process. Integration with the manufacturing process, thereby improving the quality and efficiency of the product manufacturing process. The Gallup MDC system helps companies solve this problem.

Production data and equipment status information collection and analysis management system MDC (Manufacturing Data Collection & Status Management) is mainly used to collect the working and operating status data of CNC machine tools and other production equipment, to realize the monitoring and control of equipment, and to collect the collected data. Analysis and processing can also provide data support for other software such as MES and ERP. MDC system is an integration of machine tool data acquisition system and machine data analysis and processing system. It is a shop application management and decision support system with functions such as data acquisition, machine tool monitoring, data analysis and processing, and report output. ^[1]

Data collection refers to the process of automatically collecting information from analog and digital units under test such as sensors and other equipment under test.

With the widespread use of computers today, the importance of data collection is very significant. It is computer with external

For most manufacturing companies, the automatic data acquisition of measuring instruments has always been annoying. Even if the instrument already has an interface such as RS232 / 485, it is still using manual measurement while recording to paper and finally entering it into the PC. The processing method is not only arduous work, but also can not guarantee the accuracy of the data. Often the data obtained by management personnel is already a day or two of data lagging behind; and how to achieve high efficiency for on-site bad product information and related output data Simple, real-time data collection is a big problem.

· Real-time collection of output data from the production line or the number of defective products, or the type of failure of the production line (such as line stop, material shortage, quality), and transfer to the database system;

· Receive information from the database: such as production planning information, material information, etc .;

· Transfer the name and quantity of defective products at the inspection station;

Connect the detection instrument to realize the digitization of the detection instrument. The data acquisition instrument automatically obtains the measurement data from the measurement instrument, records it, analyzes and calculates it, and forms the corresponding types of graphics to automatically judge the measurement results, such as the beating of mechanical processing parts Measurement, drawing of tension curve of tension meter, etc .;

At the same time, the real-time data collection also enables the system to achieve real-time monitoring, identify problems early, and avoid greater losses.

The software part should write the program of S3C4510B part and CPLD control program separately. The former can be divided into C / OS transplantation and the writing of various applications, the latter is used

The data collector is also called an inventory machine or a handheld mobile computer. Its main features are integration and mobility, with a compact size, light weight, complete performance, and handheld operation. Scanning a bar code with a mobile phone to record data into a smart phone can be regarded as a typical example, which is really convenient and practical. How to choose a bar code data collector in practical applications?

First, understand the basics of the data collector before you can choose. In fact, it is the integration of scanning and data. Since the battery can work, the data collector supports offline operation. It also supports the functions of real-time acquisition and display, data storage, transmission and processing automation, making the data accurate, timely, practical and reliable.
When choosing a bar code collector device, you should know that there are generally handheld and fixed types, as well as batch processing and wireless types. Hand-held, as the name suggests, you can use it to move and collect barcode data, while the fixed type is fixed at a certain place. The batch data collector supports USB and serial data lines to communicate with the computer and support offline work. The wireless data collector is connected to the local application server and updated at any time through the wireless network. In batch processing mode, after the bar code is collected, the information is transmitted to the computer through the cradle. The wireless method supports real-time data exchange with personal computers. In general, the price of bar code collectors that perform batch processing alone is relatively low compared to wireless collection. Which type is selected, this depends on the actual use situation to determine which type to use.
The choice of data collector should also pay attention to capacity and speed factors. Whenever you use a data collector, you will encounter the problem of how much data you want to collect. If the amount of data is large, you need to choose a large capacity, which is actually the processing speed. Due to the continuous research and development of high-end digital circuit technology, in the main structure of the collector, the CPU generally uses a 16- or 32-bit processor, and the higher the number of bits and the main frequency, the higher the data collection and processing capacity of the collector, The stronger the speed, the higher the work efficiency. Most of the memory uses FLASH-ROM + RAM type, which can retain information under long-term non-power supply, and the fast read and write speed ensures efficient operation. The increase in memory capacity makes data processing faster at one time. . Especially when the amount of data is relatively large, the capacity and operating speed must be budgeted in advance. Do you need to support large screens and large-capacity batteries? Some applications require a larger collector screen so that users can easily view the data at any time. At the same time, some occasions require continuous use for a long time. At this time, the power supply capacity of the battery must be considered, and how long it can be recharged. Barcode collection equipment, display screen, CPU can bring power consumption, and some structures can support battery work. Barcode collection scanning and keyboard input are two important device input channels. Most of the collectors have screens, and they can also support high-precision display of Chinese and English and graphics as required.
Purchase a data logger to consider whether programming is required. More often, after the bar code information is collected by the collector, it needs to be processed immediately to convert directly visible results. This requires secondary programming and development based on the equipment.
Consider the interface when purchasing a data collector. The interface of the bar code data collector is selected according to the actual equipment. Generally, there are serial ports, infrared ports, and parallel ports that can be connected to multiple types of standard serial and parallel port devices to transmit data. Wireless ones can also directly transmit data.
Data collector equipment should be widely used in various fields such as goods entering and leaving warehouses, express logistics, administrative and enterprise management systems. The above are some points that should be paid attention to when choosing a data collector based on actual experience.
