摘要: 针对现有工作面“三机”状态监测装置体积庞大、安装困难、维护不便、无法在线升级程序等问题，开发了基于C8051F040单片机的本质安全型“三机”状态监测分站，采用IAP技术实现了“三机”状态监测装置的在线自动升级。改进后的分站体积仅为原有分站的1/10，可与原有监测总站连接，实现对工作面“三机”状态的在线监测和故障诊断。样机测试结果表明，改进后的工作面“三机”状态监测装置运行可靠，监测准确，可实现在线升级功能。Abstract: For problems that existing condition monitoring device for three machines on mechanized mining face is bulky, difficult to install, inconvenience to maintain, and cannot online upgrade program, an intrinsic safety condition monitoring sub-station for three machines based on C8051F040 MCU was developed, and IAP technology was used to achieve online automatic upgrade of condition monitoring device for three machines. The volume of the improved sub-station is only 1/10 of original sub-station, and the improved sub-station can be connected with the existing master station and achieves online monitoring and fault diagnosis of three machines on mechanized mining face. The prototype test results show that the improved condition monitoring device for three machines on mechanized mining face runs reliably, monitors condition accurately and has ability to update programs online.
