摘　　要：中波转播台站使用的各发射机和报警系统,因时间设置不同,在长期运行下容易产生误开、误关、误报的情况。引入全球定位系统(GPS)授时系统使各设备时间上同步,可以很好地解决这一问题。GPS授时系统辅助新型定时控制器由GPS模块、时钟模块、控制模块和触摸显示屏4个模块构成,使用GPS授时保证各设备时间统一精确,并采用DS12C887芯片确保断电存储。GPS授时系统操作便捷,可人为校验及定时操作,且自动授时精准,极大程度地避免了时间误差对设备造成的影响。The transmitters and alarm systems used in medium wave broadcast stations are often prone to issues such as false open,false close,or false alarms due to disparate time settings during extended operational periods.The introduction of GPS timing system to synchronize the time of each equipment can effectively solve this problem.The GPS timing system,assisting a new type of timing controller,comprises the four modules of the GPS module for precise timing,a clock module,a control module,and a touchscreen display.GPS timing is used to ensure the uniform and accurate time of each equipment,and DS12C887 chip is used to ensure power-off storage.GPS timing system is convenient to operate,it can be manually verified and timed,and the automatic timing is accurate,which greatly avoids the impact of time errors on the equipment.
