Bar code Hand Terminal, also known as inventory machine, handheld computer. It is a terminal computer device that integrates bar code scanning device, RFID technology and data terminal with battery operation. With real-time acquisition, automatic storage, instant display, instant feedback, automatic processing, automatic transmission. It provides guarantee for the authenticity, validity, real-time and availability of on-site data. It is integrated, maneuverable, small in size, light in weight, high in performance, and suitable for hand-held features.
Both mid-range and advanced data collectors have a wider range of capabilities than entry-level data collectors. The difference between advanced and intermediate is usually CPU speed. In other words, advanced data collectors typically require faster CPU speeds, which is critical for microcontroller configuration.
Advanced data collectors are typically used in more complex residential settings and three-phase industrial applications. The higher the computational demand, the higher the CPU performance requirements. The main frequency above 200MHz is usually the best choice. The advanced data logger also features more advanced communication and control features such as Ethernet and Wi-Fi, an LCD interface for interactive display, and a USB host for local data download. These new features require more flash and system memory and require a real-time operating system (RTOS).
Relative to the entire system, the data collector may be a negligible small component, but it carries out the important task of improving the intelligence of the grid. In addition to data collection from electronic meter pools, data collectors can be configured for a variety of practical operations: checking transmission quality, monitoring power usage data, providing event data records, and reporting system failures. Whether it's an entry-level, mid-range or advanced data logger, choosing the right 32-bit microcontroller simplifies development and creates a cost-effective solution. When selecting a microcontroller, engineers should consider on-chip resources and other design factors such as device reliability (temperature and humidity range, data retention, fast transient transient reliability, anti-static, etc.), system-level component integration, Differentiating features (such as data encryption) and of course price factors.
Bar code Hand Terminal, also known as inventory machine, handheld computer. It is a terminal computer device that integrates the bar code scanning device with the data terminal and has a battery that can be operated offline. With real-time acquisition, automatic storage, instant display, instant feedback, automatic processing, automatic transmission. It provides guarantee for the authenticity, validity, real-time and availability of on-site data. It is integrated, maneuverable, small in size, light in weight, high in performance, and suitable for hand-held features.

Data collectors, called inventory machines, handheld computers, are integrated, mobile, small, lightweight, high performance, and suitable for handheld. This data collector mainly collects barcode or rfid information. Because it has an operating system, the data collector itself processes data, and also has mobile data transmission functions such as WIFI, GPRS, Bluetooth, etc., which can be easily moved or outdoor.
An information tool used to collect content such as web pages, forums, etc., directly saved to data or published to the network. The original web page can be automatically collected according to the rules set by the user, and the content required in the format web page can be obtained, and now developed into a tool (system) that can also process the data. For example, the SQL Server 2008 Performance Data Collector allows us to create a central database to store performance data; it contains three built-in data collection groups to collect and store data; to help us identify and troubleshoot SQL Server performance issues, we can use It has three built-in reports to view the collected data.
The 4C5000W has a central processing unit (CPU), read only memory (ROM), read/write memory (RAM), keyboard, on-screen display, and computer interface. Bar code scanner, power supply and other configurations, the handheld terminal can be connected to the computer through the cradle for receiving or uploading data. The running program of the handheld terminal is compiled by the computer and downloaded to the handheld terminal, and the corresponding functions can be completed according to the use requirements.
