Self-reliance type pneumatic - valve structure of multiprocessor

Self-reliance type pneumatic control valve of the control side of the SCADA system center known as the master station, actually refers to collect all data well to process remote terminal display, in the form of juice machine system. The HOST is also called the HOST. When an operator cat to the remote device. Through this gate courageously computer system related to R sichuan issue instructions. Used to rev as pumps and compressors. Change control configuration. Turn on or off the pipeline broad group, etc. The basic function of master station remote collection of data and realize the remote control and operation. And about the combination, explain the operation, display information operation. Know the help function have accumulated historical data, help, scheduling, preparation of management reports, such as flow juice. Brake control center is located in the pipe head sometimes. Sometimes in the station at the end of the pipe. Headquarters is located in the oil and gas companies. If the lateral control center in a fire, flood or earthquake the location of the vulnerable to damage, so, the master station and for sichuan and separate the main dish. When the master station and the data transmission between the independent station please usually start from the main continuous scanning all the an 'analog data reported for or change of state, etc. And authorizing simulation setting and state changes. As self-reliance type pressure pneumatic - valve structure of multiprocessor technology development, the bureau of city network ( With N) Has extensive application in SCADA system is standing. Although all sorts of bureau of city network topology structure is different, but they all share the function of each processor or workstation. The processing or workstations can provide redundancy to each other. As a backup. Read and write database model of SCADA. Handling various tasks. LAN technology will peripherals ( Zi, sheng, printer, client, etc. ) As part of the network. Directly in online database. The SCA - DA system peripherals from the main processor to the standby switch processor was simplified. Self-reliance type pneumatic - valve to quote according to use DMA interface between two computers of double juice machine principle of redundancy. Because can be purchased from each computer maker standard software package of computer systems, therefore, to improve the utilization ratio of the system total master station computer system with technology usually is standardized.
