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.
Customer site is a large construction site in remote mountain areas, a distance of 3,5 km of hillside Information Center there are two million tons of tower crane, used to transport cement and water, etc., in the crane's hook on the data control device, the client need to implement these large amount of data information transmitted to the information and West, because the tower crane at the device is your serial device, the central server is the Ethernet device, the early customers with 2.4G Ethernet port into a serial port and then connected to the controller, but because the crane is moving in the opposite direction will stop the movement to the antenna, so often off the net, can not communicate properly.
iNET300 industrial radio frequency band is low, transmission distance, through diffraction ability, speed up to 512kbps, and iNET300 with an Ethernet port and two serial ports, and can also communicate, iNET300 built-in multi-interface protocol conversion, so is the serial port can also be remote, the center is a network port, a radio will solve the problems of the user's block, interface conversion, transmission distance close to many problems.
System structure:
Programme Description:
1, in the information center established at a high roof bracket for mounting antennas, covering the entire site, radio station placed in the data processing center of the room, through the cable and antenna connections.
2, the remote device installed in two crane hooks at the top (because of a huge crane, can stop five people) with a car antenna and device connections.
3, the radio set to a center, two remote, central information center with the Ethernet port to connect the server, the remote device with RS232 serial port controller, Serial to Ethernet conversion.
