Abstract：What are the aspects of 6 -inch handheld terminal PDA purchase?| Ruggtables
PDASPC's market demand has always been very large. Today, I will take this 6 Inch Android PDASPC for example. When we buy PDA, we need to focus Only on the side will not step on the pit. Barbara will introduce from the five levels of specifications parameters, function Module, manufacturer, quality control system and brand price.
2) 6 Inch Android PDASPCPDA function Module
3) 6 Inch Android PDASPCPDA manufacturers How to choose
1) 6 Inch Android PDASPCPDA specification parameters
We are looking for every one When model 6 INCHPDASPC, they should carefully check the specifications of the product and whether optional accessories match with our project application scenarios. If not match, it should be adjusted in a timely manner.

1. Bar code scanning
Barcode code Scan is one of the important functions of PDASPCZUI. It is to attach the coded barcode to the target and use a dedicated scanned read-WRITE to use the light signal to transmit information from the strip magnetic to the scanned-write. There are currently two technologies, laser and CCD, laser scanning can only be knownRead 1D barcode, CCD technology can identify 1D and 2D barcodes.
2, RFID identification
RFID identification Similar to barcode scanning, but RFID uses a special RFID handheld PC and a special RFID label that can be attached to the target, using the frequency signal to transmit the information from the RFID tag to the RFidream-Write.
3, fingerprint collection, comparison
equipped with fingerprint collection module, collecting biological fingerprint information and For comparison, it is mainly used in areas with higher security requirements for public security, banking, and social insurance.
4, GPS positioning
Systems that use GPS positioning satellites to carry out a system of positioning and navigation in real time in real time, called global satellite positioning system, referred to as GPS, industry applications are mainly used for public security, and larger in the civilian market, for driving People provide electronic maps and positioning services.
5, GSM/GPRS/CDMA wireless data communication
For real -time data exchange. Used in applications with high -time requirements for data.
6. Image acquisition
In order to meet the application needs of the current stage, the current PDAS is basically basically They all have cameras for image collection, and are mostly used for on -site law enforcement, on -site information collection and other applications. This 6 Inch Android PDASPC only supports four features of the above barcode recognition, GPS positioning, wireless data communication and image acquisition, and does not support RFID identification and fingerprint acquisition and comparison.
3) 6 Inch Android PDASPCPDA manufacturers How to choose
I feel that high -precision smart hardware devices such as this data collector are more reliable for foreign companies designed and developed, but it is not. With the development of the economic level, my country's scientific and technological level has improved significantly, especially in the field of Internet of ThingsEssence With the rapid development of the Internet of Things, many PDAS manufacturers and agents have appeared at home and abroad. The quality of the product is uneven, which brings troubles for consumers during the choice. In the face of a variety of PDAPDAS products in the market, how should consumers choose? For this issue, Barbara brings the following suggestions to buy satisfactory products.
1. Select PDAS Products according to project needs
Operating system: PDAS operating system Divided into Android and Windows. The two systems can be selected according to the specific
project needs. AndroidPlatform is known for its openness and freedom, and customers can develop secondary development on PDAS. Windows is more stable in operation.
Screen resolution: higher resolution can well support the software, display the operating interface in the state of ZUI, improve the user experience. Suitable Brightness and contrast also play a protective role in the vision of the operator.
Scanning head: 1D code and 2D code to make a choice according to the needs of the project. You need to use a dedicated scanning head, just install 2D code scanning software and the camera to use it.
Power Configuration: The smaller the battery consumption, the better, and the ZUI uses a high -voltage and large battery.
Protection level: The higher protection level can ensure that the product runs stably in the harsh industry environment without affecting work efficiency.
Data transmission function: dual-frequency five-mode Wi-Fi, with unique signal amplification technology to meet retail, medical treatment, etc. FI requires high industry applications.
2. The reputation and strength of the manufacturer
Large factory selection: The size of the manufacturer is based on the quality and service of the product.
Factory strength: When choosing a manufacturer, you need to fully understand the manufacturer's productivity, innovation, after -sales service and product quality.
6 INCHPDASPCPDA quality control process generally includes Material inspection, first inspection, semi -finished product inspection, aging testing, finished product inspection, packaging before and after inspection, etc.
- 2. reliability experiments
The reliability experiments of PDA generally include the entire PC falling experiment, the steel ball falling experiment, high Low -temperature testing, salt fog testing, vibration experiment, drum testing, etc., through multiple reliability experiments to ensure the industrial characteristics of PDASPC.
3. The complete certification system
In order to ensure the quality of PDASPC's industrial -grade, it is necessary to certify the PDA. The certification of a PDASPC in the industry is the US military standard 810G test, IP certification and 3C certification. Sexual, if there are business exporting foreign business, you will also do CE certification, GMS certification, etc. Compared with manufacturers who only do domestic markets, manufacturers of domestic and foreign countries, whether they are service or market competitiveness, competitiveness in the market and market competitiveness. For speaking, foreign manufacturers are better. For the entire market of industrial -grade tablets, foreign countries are still relatively large.
5) 6 Inch Android PDASPCPDA brand and price
A 6 Inch Android PDASPC. If the hardware Configuration is exactly the same, it does not mean Where is the value of value?
1. Brand brand benefits This must be based on the big brand. If it is some small small brands The brand and the company can almost ignore it, but it cannot be said that the better the big brand's products must be, because they also have a possibility to find someone else to do it.
The cost mainly includes the various molds, material costs, and research and development handheld PCs.Specific cost
3. Shipping For reference, the larger the shipment PDA, the moreProducts are often more stable and more in line with the user's usage scenario. The experience will be better
The value of a handheld PC is not only reflected in the price, but it is more reflected in subsequent services and technical support. After -sales is very important for customers, because who dares to guarantee that their products will not appear any of any product.What about the problem?
