With the country's rapid development of information technology, industrial data transmission requirements are increasing, not only the requirements of reliability and stability, and requires to meet anytime, anywhere to transfer large amounts of data services. To meet the data transfer anytime, anywhere Many domestic and international digital radio can meet, but the data rate is very small, the maximum is 19.2kbps, but now large companies such as steel, petroleum, chemical and other industries most advanced in Ethernet port PLC / RTU to achieve the management and control, and the amount of data in tens or hundreds of Kbps Kbps, apparently the traditional data radio is unable to meet the needs of large industrial data transmission, with the popularity of industrial Ethernet transmission , a small amount of data from traditional to high-speed serial transmission of large Ethernet transmission change is inevitable.
According to customer needs, requirements in the steel to be weighed in the delivery process, and weighing equipment spread over more within 3 km radius of the nine areas, but with that-go, randomness is very strong, because the steel plant environment , wiring is clearly impossible, ordinary data radio were powered by polling the way, can not take the initiative to report, most of the traditional 2.4G microwave Ethernet port, take the initiative to meet the data sent, but the complexity of the steel plant environment , and is weighing equipment in the plant, the required transmission through the plant to the data processing center is not possible, the user after many discussions, the company decided to use low-frequency Shenzhen Huaxia Sheng industrial Ethernet radio iNET300 to achieve.
iNET300 industrial radio-band low-, 340MHz, transmission distance, through diffraction ability, speed up to 512kbps, and adapt to the ambient temperature range, is ideal for large enterprises plant, mine industrial Ethernet data transmission, and customers to need to use multipoint transmission of the remote up to 50, with a center and a remote Ethernet port and two serial ports, and serial and Ethernet simultaneously and communicate with each other, to provide users with flexible applications, saving investment.
System structure:
Programme Description:
1, Top side up in the center of a pole plant to install the antenna, covering the entire plant, radio station placed in the data processing center of the room, through the cable and antenna connections.
2,The remote device installed in each plant and, with tens of centimeters of the small omni-directional antenna to connect the radio.
3, Divided into central and remote stations, but if the central problem, the customer can always take a remote center can be set to communicate in order to ensure the entire system, or to use hot standby radio to resolve.
4, The device itself with an Ethernet port, two serial ports, these three interfaces can communicate, you can only communicate with an Ethernet port, remote is the serial port can also
