    电力线宽带载波对比窄带载波的优点
    Advantages of broadband carrier power line carrier to narrowband carrier
    窄带和宽带电力线载波方式,在应用实施方式上有很多类似的地方,如借助电力线网络实现通信节点间免布线或少布线,但在通信机制、通信协议、载波和调制方式等方面具有巨大的差别。
    There are many similar places in the way of application and implementation of narrow band and broadband power line carrier, such as the use of power line network to realize no wiring or wiring between communication nodes, but there are great differences in communication mechanism, communication protocol, carrier and modulation mode.
    (1)高速数据传输,宽带载波通信速率高达2Mbps远**窄带载波的几十K或几百Kbps。
    (1) high speed data transmission, broadband carrier communication rate up to 2Mbps is much higher than that of narrowband carrier tens of K or hundreds of Kbps.
    (2)实现远程控制通断电功能,窄带由于中心频率较低难以实现实时抄通。宽带避免了断电之后难以送电现象,实现实时抄表通断电功能。
    (2) realizing remote control and power outage. Narrowband is difficult to realize real-time copy because of low center frequency. The broadband avoids the phenomenon of difficult power transmission after power failure and realizes the function of power failure in real-time meter reading.
    (3)宽带载波中心频率为2-12MHz,远**窄带东软(270KHz)、晓程(120KHz)窄带频率。正由于中心频率的增加,从而增加应用层的存储空间,从而达到同时向电力线并发多个载波数据帧的效果。宽带载波可以在同一时间内下发5-10条抄表命令,每块表应答时间为200-500毫秒。窄带载波每抄一块表及应答时间约为10-15秒。
    (3) the broadband carrier center frequency is 2-12MHz, much higher than that of narrowband Neusoft (270KHz) and Xiao Cheng (120KHz) narrowband frequency. Due to the increase of the center frequency, the storage space of the application layer is increased, so as to achieve the effect of simultaneously concurring multiple carrier data frames to the power line. The broadband carrier can send out 5-10 meter reading commands at the same time, and the response time of each table is 200-500 milliseconds. The narrowband carrier has a copy of one table and a response time of about 10-15 seconds.
    (4)多个数据量的抄读,正由于宽带载波抄读数据快(300块表、一个量<1min),窄带载波(300块表、一个量约3-4个小时,线路好的情况下)。宽带载波可用剩余时间抄收其它电表数据量,从而解决如偷窃电等客观问题。
    RVVP屏蔽电缆(4) the reading of multiple data amounts is due to the fast reading of the broadband carrier (300 blocks, one <1min), the narrow band carrier (300 tables, one volume of about 3-4 hours, a good line). The broadband carrier can use the remaining time to copy the data of other meters, so as to solve the objective problems such as stealing electricity.
    (5)宽带载波通信速率高,可以在较端的时间内完成数据传输,可大大降低遭受突发干扰的影响,即使一次通信失败,也可迅速进行重发,确保数据可靠,现场抄表率大幅提高。
    (5) the broadband carrier communication rate is high, can complete the data transmission in the extreme time, can greatly reduce the impact of the burst interference. Even if one communication fails, it can be reissued quickly to ensure that the data is reliable and the field copying rate is greatly improved.
    4、宽带载波对比塑料光纤的优缺点:
    RVVP屏蔽电缆4. The advantages and disadvantages of the broadband carrier compared to the plastic optical fiber:
    宽带电力线载波对比塑料光纤通信方式,同样具有传输带宽高,传输速率快等特点。但在通信机制、一次性抄表成功率、抗干扰能力、施工安装布线等有着巨大的差异:
    Compared with plastic optical fiber communication, broadband power line carrier has the characteristics of high transmission bandwidth and fast transmission speed. But there are great differences in the communication mechanism, the success rate of disposable meter reading, the anti-interference ability, the installation, wiring and so on.
