基于RS485总线的数字电视发射机远程监测系统

Remote monitoring system of digital TV transmitter based on RS485 bus

介绍了一种基于RS485总线的数字电视发射机远程监测系统,可实时监测发射机的工作温度、功率、工作电压、工作电流等状态,并具有显示报警功能。系统由一个主机和多个从机构成,主机和从机通过RS485进行通讯,从机通过I2C总线采集数据。系统成本低、可靠性高、使用方便,可用于多种远程监测场合。

A remote monitoring system of Digital TV transmitter based on RS485 bus, which can detect real time working temperature, power, voltage, current and other parameters of transmitter, with the ability of display and alarm, is introduced in this paper. The system is made up of one Master and many Slaves, which communicate with each other byRS485 bus. Slave samples data by I^2C bus. This monitoring system is of low cost, high reliability, convenient to use and can be applied to many remote monitoring situations.
