Data collector is also known as inventory machine or handheld mobile computer, its main feature is the unity and mobility, with a small size, light weight, complete performance, can be handheld operation. Nowadays, the scanning of barcodes with a cell phone will be recorded into the smartphone data, can be regarded as a typical example, is really convenient and practical. In practice, how to choose the barcode data collector? First of all, understand the basic knowledge of the data collector to choose a good. In fact, it is the integration of scanning and data realization, because it can work through the battery, so the data collector supports offline operation. It also supports real-time acquisition and display, storage of data, transmission and processing automation to make data accurate and timely, practical and reliable. Below to understand the two types of data collection to know when buying Choose barcode collector equipment, know that there are generally divided into handheld and fixed type, but also divided into batch processing and wireless type. Handheld, as the name suggests, can be held in the hand to move the collection of bar code data, while the fixed type is fixed in a certain place. Batch type data collector support USB and serial data line, and computer to achieve communication, support offline work. Wireless data collectors are connected and updated with the local application server at any time through wireless network. The batch mode transmits information to the computer through the communication seat after the barcode is collected. The wireless method supports real-time data exchange with a personal computer. In general, a separate batch of bar code collector price relative to the wireless collection of a lower point, choose which type, this according to the actual use of the situation to decide to use that type. Select the data collector should also pay attention to the capacity and speed factors Whenever the use of data collectors, will encounter the problem of how much data to be collected, if the amount of data is large, you need to choose a high-capacity, in fact, is the speed of processing. Due to the continuous research and development of high-end technology of digital circuits, in the main structure of the collector, the CPU is generally used sixteen or thirty-two-bit processor, and the higher the number of bits and the main frequency, the collector of data collection and processing capabilities, the stronger the speed, the higher the working efficiency. Memory is mostly used on the FLASH-ROM + RAM type, able to retain information in the case of persistent power supply, and faster read and write speed to ensure that the operation of the high efficiency, the increase in memory capacity so that the data of a one-time processing faster. Especially when the amount of data is relatively large, the capacity and operating speed should be budgeted in advance. Whether you need to support a large screen, large-capacity battery Some applications require a larger collector screen, so that the user can easily view the data at any time. At the same time, some occasions need to be used continuously for a long time, this time to consider the power supply capacity of the battery, how long it can be recharged. Barcode capture device, display, CPU can bring power consumption, part of the structure can support battery operation. Barcode capture scanning and keyboard input are two important device input paths. Most of the collectors have a screen, according to the need they can also support the Chinese and English and graphic high-precision display. Whether to choose the data collector needs to be programmed More often than not, after the collector collects the bar code information, it needs to be processed immediately and converted into directly visible results. This requires secondary programming and development on the basis of the device. Interface: According to the actual equipment to choose the barcode data collector interface: generally serial port, infrared port, parallel port can be connected with a variety of standard serial port, parallel port equipment to transmit data, wireless can also directly transmit data. Data collector equipment should be widely used in goods in and out of the warehouse and express logistics, administrative and enterprise management systems and other fields. The above is based on actual experience written by the data collector selection should pay attention to several matters.
