高稳定高可靠的SFS-Ⅱ型遥测地震台网时间服务设备

Very stable time service equipment SFS Ⅱ for telemetric seismic networks

ＳＦＳ－Ⅱ遥测地震台网时间服务设备是继国家地震局于７０年代投资研制的“７６８”钟站后，为模拟遥测地震台网研制并投入小批量生产的换代产品。该产品自１９９３年研制完成后，成功地运用在西昌大桥水库，青海花土沟油田，黄河小浪底和李家峡水库等遥测台网记录中心。其核心部件：ＳＺＺ－Ⅰ型数字钟和ＢＰＭ接收机，先后被成都遥测台网，自贡遥测台网，丹江水库台网，西藏遥测台网，隔河岩水库，龙羊峡水库，长江三峡水库前期台网等国家大中型遥测台网选用，均获得了优良的时间服务，为台网的高可靠，高质量运行提供了保证。ＳＦＳ－Ⅱ型遥测地震台网时间服务设备，在整体设计上考虑到各地台网不同的要求，设备的有关部分可根据需要进行增减组合。在技术上该设备还采用了可编程器件，根据我国遥测台网实际工作的需要，增加了多项功能，增强了可靠性，使用操作简单，维护方便。

The time service equipment(TSE)SFS Ⅱ for the telemetric seismic networks(TSN) is an advanced product developed for analogue telemetric seismic networks in 1993 following the clock 768 which was invented and produced by the State Seismological Bureau of China in 1970s.The complete sets of the equipment STS Ⅱ have been operating successfully in the recording center of the TSN at Daqiao Reservoir,Xichang,Sichuan Province,at Huatugou Oil Field and Lijiaxia Reservoir in Qinghai Province,and at Xiaolangdi Reservoir on the Yellow River,Henan Province.The digital clock SZZ Ⅰ and receiver BPM are the main components of the equipment.The have been working in the large telemetric seismic networks of our country such as Chengdu and Zigong in Sichuan Province, Sanxia Reservoir on the Yangtse Reiver,and Cheyan Reservoir in Hubei Province,Lhasa city in Tibet,and Longyanxia Reservoir in Qinghai Province.Both the whole sets and the main components of the equipments in all the networks have obtained the excellent time service,and have ensured the networks' high stability and high reliability. The design of the SFS Ⅱ has considered the requirements of different networks,so some parts can be added or removed for the whole equipment to be optimized.In technology,the programmable components are used and more functions are added.The equipment is very easy in operation and maintenance,so it is convenient to be put in a wide application in the telemetric seismic networks in our country.
