同样因为这个原因,在网上寻找的如-2所示的电路也以失败告终。为了能够对差分放大电路提供统一的参考基准终对-2进行修改,分别从差分输入的+端和-端引一个大电阻到测试系统的“地”,因为是单电源放大考虑到LM358的共模输入信号范围0-VCC-1.5V,由于二极管限幅,二极管两端电压多0.7V,又因为对于去其中间电平连接到地,正负端对地输入的电压范围为-0.35到+0.35。终电路如所示,该电路可以实现设计功能。

With the same negative level transmission, when in the light, their impact on the two wires are the same, thus reducing difference at the receiving end can block this (minus operation performed can be understood as a difference of two way). It can be seen from the principle of double stranded lines that the purpose of double stranded lines is to transmit. Therefore, when we make the joint of the twisted pair, we must not separate the two different transmission lines, otherwise it will greatly affect the transmission of the network.

Armoured communication cable armoring cable type: HYA53, HYAT53, HYA23 HYAT23, HYV22, HYA22 (rat, buried) armoring communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and designed and vulnerable to erosion area telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter. 5. The marking contents of armored communication cables include: wire diameter, number of wire pairs, cable model, length, manufacturer name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical re of the basic cable. 6. Cable length: mechanically protected cable is made according to the length of the corresponding basic cable

dcs应该熟悉,它就是集散控制系统。FCS其实就是现场总线控制系统。FCS是什么?FCS就是现场总线技术和基于现场总线的总线装置(现场用的变送器、执行器及其它现场仪表)和控制室内的设备构成控制系统。同时FCS是建立在全数字通信基础上,而且可以说是一种完全分散的控制系统。DCS是什么?DCS它是以微处理器作为基础的分散型控制系统,采用控制、显示、计算机、通信等技术。主要是分散控制、集中管理,对生产过程起到集中监视和操作管理,而且现场的控制任务都是由不同计算机控制装置去执行。

  4、使用特性:电缆敷设温度应不低于0℃,电缆导体的长期允许工作温度为70℃。电缆允许的弯曲半径:对铠装的电缆,应不小于电缆外径的6倍。对有铠装或铜带屏蔽结构的电缆,应不小于电缆外径的12倍。对有屏蔽层结构的软电缆,应不小于电缆外径的6倍。
