Many people have purchased data collectors and scanners, but they do not know what's different between them. Let's talk about differences between data collectors and scanners:
1. Data collector, commonly known as inventory machine. There is a memory that can be used without connection to a computer, and the distance from the computer is not restricted, and even different cities can use the network. The scanned data is first stored in the memory of the collector, and then the data is transmitted to the computer server through the transmission base or GPRS or wireless WIFI to complete batch processing. Second, the collectors have large screens and you can see the scanned bar code information at any time. Finally, the collector has a keyboard. If the barcode is wrong, or the damage cannot be scanned, the keyboard can be used. The data collection system is relatively flexible and is a system that is tailor-made for a wide range of users. The data collector is converted into various physical quantities of electrical signals. Temperature, water level, wind speed, pressure, etc. can be analog or digital. Collection is usually a sampling method, that is, repeated collection of data at the same point at certain times. Most of the collected data are instantaneous values, and may also be a characteristic value within a certain period of time. Accurate data measurement is the foundation of data collection. Data measurement methods are touch-based and non-touch-based, with a wide variety of inspection components. Regardless of the method and component, the condition of the target under test and the measurement environment are all conditioned to ensure the correctness of the data.
2. Scanning guns, also called scanners. No memory, just instant transfer. When a USB cable (or ps2 port, RS232 port) is connected to the computer, a bar code is scanned and a code data is immediately displayed on your computer. Wireless scanners, also known as wireless scanners, can be used without connection to a computer, but the spacing is limited. Usually 100 meters, it is best to be accessible. Second, the scanner does not have a screen. The scanner will convert the bar code compiled according to certain rules into what the user can read, that is, the information it contains, the two processes of demand scanning and decoding.
With the development of smart phones, more and more mobile phones have become the standard for people's daily life. We are thinking that PDAs and mobile phones are also Android systems. Can we use mobile phones instead of PDA functions? And now mobile phones are in hardware. The system aspect is better than the PDA. Therefore, the WT01 wearable intelligent data acquisition terminal emerged. It can realize all the functions of the PDA in combination with the mobile phone, and it must be closer to the people in the secondary development than the PDA development because it is used in the Android mobile phone application. In development, the technology is more mature and the resources are relatively abundant. As long as it is a general Android software engineer, it can be easily developed.
