Reference
WIFI is from AP (Access Point) and wireless network card wireless network components. AP is usually referred to as network bridge or access point, it is treated as a traditional wired LAN and wireless local area network as a bridge between, so any PC equipped with a wireless network card can be shared through the AP to Wired LAN network, and its working principle of a built-in wireless transmitter of the HUB or routing, and wireless network card is responsible for receiving the signal emitted by the AP's customer premise equipment. And wireless b / g express card model, in accordance with its speed and the new and old technologies can be divided into the
Industrial-class wireless data acquisition system does not need like an ordinary portable industrial grade wireless data acquisition system as relying on the Block and PC communication for data exchange, and can be directly through a wireless network and the PC, the server in real-time data communication. To use the industrial grade wireless data acquisition system is necessary to establish a wireless network. AP wireless network equipment to connect the equivalent of a wired LAN and wireless network bridges, through twisted-pair or coaxial cable access network Ethernet or Token Ring, industrial-class wireless data acquisition system with the AP through the wireless communications and LAN server data exchange. The biggest advantage of GPRS is that it's not WAP data transmission speed can be compared. At present, the GSM mobile communications network for the transmission speed of 9.6kbps, GPRS mobile phone when it is launched in the beginning of this year have reached a 56Kbps transmission speed, up to now reached a 15Kbps. GPRS is a packet-switched data transmission manner, because it is packet switching, and therefore the utilization of network resources than circuit-switched greatly improve, but at the same time GPRS voice and data transmission. Existing WAP is carrying circuit-switched (CSD) methods, circuit-switched data and voice mode should not at the same time. Industrial-class wireless data acquisition system and computer systems are basically used to connect a variety of ways, TELNET terminal emulation connection: In this way, industrial-class wireless data acquisition system itself does not require the development of applications. TELNET services only through access to the application server, a remote server running the above procedure. In this way to work, because a large number of terminal emulation control data flow in the industrial-class wireless data acquisition system and server exchange, communication efficiency will be relatively low. However, as in the industrial-class wireless data acquisition system on the need for developing applications in the system upgrade will be relatively simple. Traditional C / S structure: industrial-class wireless data acquisition system as a CLIENT-side, industrial-class wireless data collector above the user's application flow in accordance with the requirements of the development process. Development platform and portable, as different products vary. Work in this way, industrial-class wireless data acquisition and communication between the server only need to exchange data and information collected, a small amount of data, communications, the higher the efficiency of the corresponding. But as portable industrial grade wireless data acquisition system, as per the industrial-class wireless data acquisition system required to install applications, upgrades for the latter seems more troublesome applications. B / S structure: in the industrial-class wireless data acquisition system embedded above browser, through the HTTP protocol and application server for data exchange. In this way the industrial-class wireless data acquisition system requirements higher, based on the WinCE / windowsmobile platform for the following products are relatively easy to realize.
Industrial-class wireless data acquisition system in real-time communication of data is strong, and high efficiency. Industrial-class wireless data acquisition system directly and server data exchange, data are transmitted in real-time. Data from the industrial-class wireless data acquisition system to issue, through a wireless network where wireless terminals to reach the current channel AP, AP, through the twisted pair or coaxial cable to connect the data cable incoming LAN network, the data finally reaches the server's LAN port into server, and then the server will return the data back through the original path to the wireless terminal. All data to TCP / IP communication protocol transmission. Operator can be seen in the industrial-class wireless data acquisition of all operating data are entered in the first back-end database, that is industrial grade wireless data acquisition system will be extended to a database information system of each operator's hands. Industrial-class wireless data acquisition system with the scene in real-time data acquisition, processing automation equipment. With real-time acquisition, automatic storage, instant feedback, automatic processing, real-time display, automatic transmission function. Real-time data for on-site, the authenticity, validity, availability to provide a guarantee. Industrial-class wireless data acquisition products technical features and portable hardware requirements, including the CPU, memory, screen display, input devices, output devices and so on. In addition, the more crucial is the wireless communication mechanisms. Comparison of currently used have a wide range of frequency hopping wireless technology, two kinds of wireless spread spectrum technology. It should be said that both technologies have their own advantages and disadvantages, but for a general warehouse logistics, retail applications, the frequency-hopping technology because of its strong anti-interference ability, data transmission stability, and therefore more widely. Industrial-class wireless data acquisition system include: IC card wireless data collector, barcode wireless data acquisition system, IC card barcode wireless data collector. Each industrial-class wireless data acquisition system is a network of its own IP address node, the landing point via wireless (AP), and network system realize the real-time data exchange. In the
In the application of industrial-class wireless data acquisition system, the specific manner in which to carry out, the application should be based on actual circumstances. Industrial grade wireless data collector application performance indicators such as temperature, humidity, seismic, and so on. As a result of industrial-class wireless data acquisition system mostly in outdoor use, the surrounding humidity, temperature and other environmental factors on industrial-class wireless data acquisition system operating impact is relatively large. Especially LCD screen, RAM chips and other key components, low temperature, high-temperature properties are restricted. So users according to their own choice to use the environment in industrial-class wireless data acquisition products. Portable hand-held wireless bar code data collector. Built-in laser bar code scanners to identify UPC barcode, EAN bar code, TOSHIBA barcode, CODE39 barcode, CODEBAR barcode, CODE11 bar code, CODE128 bar code, I 2 of5 barcode, MSI barcodes, ISBN barcodes , ISS barcode,
