| RS485/RS232 converter Intelligent Design
All obtained information on the monitoring and control objects sent to the converter, the converter receives the data, after some preprocessing, and then the data format required to write computer to the EEPROM, pending its data query computer . Therefore, the computer each time data is available converters in the EEP-ROM data recorded. Thus, other devices do not affect the working conditions of computer communication between the converter. The relationship between them just like the relationship between manager and secretary, the secretary sent the information to various departments to collate, summarize, tabulate, pictures or other written materials, and then wait for manager to take. Because this way, the computer can always get in touch with the converter, which can greatly reduce the occupancy time of computer serial port, computer CPU occupancy rate also greatly reduced, thereby improving the utilization of system resources. 3 Converter software design as converters in distributed measurement and control system equal status with other slaves, and master-slave communication system determine the characteristics of the receiving host data from the machines generally use the interrupt, the interrupt receiving block diagram shown in Figure 6 . 4 Conclusion In this paper,ugg boots billig, a general-purpose computer of the MCS 51 series single chip master-slave communication network for remote control of information inquiries and problems faced by the comparison of two programs, a more reasonable solution sets, and designed a RS488/RS23Z intelligent converter. Proved that this intelligent converter with communication efficiency,ugg stivali, reliability, intelligent prince Yu received interrupt data Converter 6, block diagram of other advantages, the converter is programmable, so applicable in all similar to the communication network,ugg prezzo, strong expansion,ugg boots günstig, with good prospects.

Total citations - that since the founding of the journal from all the papers published in the paper cited statistics that year the total number of journals can be shown that the extent of use and attention, and the role of communication in science and status. 2. Impact factor - is internationally accepted journal evaluation indicators. It can fairly assess and address the various journals. Generally, the greater the impact factor, its influence and role of academic greater.
