为保证电网安全和经济运行,各种以计算机技术和通信技术为基础的自动化装置被广泛应用,如调度自动化系统、故障录波装置、微机继电保护装置、事件顺序记录装置、变电站计算机监控系统、电能量计费系统、火电厂机组自动控制系统、雷电定位系统及输煤、除灰、脱硫等控制装置等。
随着电厂、变电站自动化水平的提高,电力系统对全站统一时钟的要求愈来愈迫切,有了统一时钟,既可实现全站各系统在统一时间基准下的运行监控,也可以通过各开关动作的先后顺序来分析事故的原因及发展过程。
因此电力系统的安全、稳定、可靠运行对时钟的基准统一及精度的要求进一步提高,在电力系统的电厂、变电站及调度中心等建立全站统一时间同步系统已经显得十分迫切和必要。
另外,各站往往有不同的装置需要接收时钟同步信号,其接口类型繁多,装置的数量也不等,所以在实际应用中常感到卫星对时装置的某些类型接口数量不够或缺少某种类型的接口,其结果就是全站中有些装置不能实现时钟同步,或者需要再增加一台甚至数台卫星对时装置,而这往往受到资金不足或没有安装位置等限制。
YJD-2000 卫星同步时钟是我公司根据电力系统现在的需要及将来的发展要求基础上,自主开发的具有国内先进水平的授时产品。
YJD-2000 卫星同步时钟结合美国GPS、中国北斗、俄罗斯格罗娜丝等技术特点并考虑了各种涉及国家安全的关联因素,实现了输入多源头(GPS、北斗、格罗娜丝、高精度守时、IRIG-B 码基准等)、输出多制式(TTL、空接点、IRIG-B、差分、串口、网络、光纤等)、满足多设备(系统输出可以任意扩展,可以满足任何规模、任何方式的时间信号需求)的要求,可为电力、煤炭、轨道交通、石油化工、航道水运、邮电电信及相关领域的系统中需要接收时钟同步信号的装置及系统提供高精度、高稳定、高安全,高可靠的时间基准信号。

HomeLink to operate a garage door or gate,you should unplug the motor for that device during training.Repeatedly pressing the remote control button could burn out the motor.They do not have the safety feature that causes the motor to stop and reverse if an obstacle is detected during closing,increasing the risk of injury.HomeLink stores the code in a permanent memory.There should be no need to retrain HomeLink if your vehicle’s battery goes dead or is disconnected.If your garage door opener was manufactured before April 1982,you may not be able to program HomeLink to operate it.The HomeLink universaltransceiver built into your vehicle can be programmed to operate up to three remotely controlled devices around your home,such as garage doors,lighting,or home security systems.For quick and accurate training,make sure the remote transmitter for the device (garage door,automatic gate,security system,etc.)has a fresh battery.If you just received your vehicle and have not trained any of the buttons inHomeLink before,you should erase any previously learned codes before training the first button.If you are training the second or third buttons,go directly to step 1.Unplug the garage door opener motor from the electrical outlet.Hold the end of the garage door opener remote 2to 5inches from HomeLink.Make sure you are not blocking your view of the red indicator in HomeLink.Always refer to the operatinginstructions and safety information that came with your garage door opener or other equipment youintend to operate with HomeLink.If you do not have this information,contact the manufacturer of the equipment.To do this,press and hold the two outside buttons on the HomeLink transceiver for about 20seconds,until the red indicator flashes.2.1.On EX-V6modelGeneral InformationImportant Safety Precautions Training HomeLinkBefore you begin HomeLink Universal Transceiver178step 1.Release the buttons,then gotosecond.If the button works,programming is complete.If the button does not work go to step 6.Pressand hold the remote transmitter button and one of the HomeLink buttons at the same time.If the red indicator in HomeLink begins to flash slowly at first,then rapidly, release both buttons, and go to step 5.Repeatthese steps to train the other two HomeLink buttons to operate any other compatible remotely controlled devices around your home (lighting,automatic gate, security system,etc.).If the indicator flashes rapidly for 2seconds then stays on,you have a rolling code transmitter:go to ‘‘Training with a Rolling Code System’’(see page ).If the indicator stays on or flashes slowly,repeat steps 2thru 5.Push and hold the HomeLink button for a few seconds,then watch the red indicator on HomeLink.3. 6.7.180HomeLink Universal TransceiverFeatures179For security purposes,newer garage door opening systems use a ‘‘rolling’’or variable rmation from the remote control and the garage door opener are needed before HomeLink can operate the garage door opener.The ‘‘Training HomeLink’’procedure trains HomeLink to the proper garage door opener code.The following proceduresynchronizes HomeLink to the garage door opener so it sends and receives the correct codes.Make sure you have properly completed the ‘‘Training HomeLink’’procedure.Press and hold the button on HomeLink for 3to 4seconds.Press and hold the HomeLink button again for 3to 4seconds.This should turn off the training indicator on the garage door opener unit.(Some systems may require you to press the button up to three times.)Press the HomeLink button again for about 1second.It should operate the garage door.Find the ‘‘training’’button on your garage door opener unit.The location will vary,depending on the manufacturer.6.2. 4.5.1.Training With a Rolling
