为了解决机房监控中数据传输实时性差、成本高以及人工巡逻效率低的问题，讨论了ARM7的数据采集和串口通信原理，针对恶劣条件下数据传输误差大的特点，提出将GPRS无线通信和高效节能芯片LPC2114相结合的设计方案。既实时、有效地将机房信息传送到监控中心，又实现了机房的无人值守。在系统组成上提出模块化设计，模块之间通信采用RS485通信方式，最大实际传输距离可达800 m，该设计既保证了数据的可靠传输，又使系统结构更加简单、性能更加稳定，为以后系统升级提供了条件。在实际应用中，无线数据终端传输速率可达40 kbps，完全能够满足将各项数据实时地传输到监控中心。

Abstract:
 In order to solve the problem of computer monitoring data transmission in real-time，high cost and low artificial patrol efficiency，this paper discussed the data acquisition of ARM7 and principle of serial communication. And the design scheme combined GPRS wireless communication and the highly effective energy conservation chip LPC2114 was presented because of data transmission error in bad environment，the system not only made the computer information transmit to the monitoring center real-time and effectively，but also realized unmanned watching.In the system composition，this paper proposed modular design，which adopted RS485 communication between communication module whose practical transmission distance can reach the maximum of 800 meters.The design makes the data reliable transmission，the system structure is simple，and the performance is stable，which also provides conditions for the system upgrading in the future.In practical applications，the transmission rate of the wireless data terminal can up to 40kbps，which completely meets the real-time data transmission to the monitoring center.
