Template:Mcrs diagrams Minecraft电报机 与真正的电报设备工作原理相同 :发送一系列长距离脉冲,由接收端进行解码。有很多种设计方法,从简单的闪烁 红石火把, 到庞大的机器,进行接收、删除、编辑,然后将他们发送到目的地. 本教程将讲解如何建造和操作这个设备。

Example Telegraph - Outside

一个中等规模的电报机设备外观

工作原理

所有不管简单或复杂的电报都需要四个东西: 发报机,、反相器(非门)、 红石线、以及接收装置. 一般发射装置是拉杆。 当然也可以是按钮或者压力板 , 但因为它们保持0.9秒的激活时间,所以不太容易创建一个消息。 另一方面,;拉杆可以在玩家想要的时候关闭, 允许快速脉冲发射电报语言,如 莫尔斯电码, 之后,他们将通过非门创建一个输出, 因为许多电报设备几乎使用红石火把来输出信号, 这意味着, 如果没有一个非门,当脉冲发射时,火把就会熄灭,虽然这只是一个外观问题, 但如果不这样做,再读取信息时将会发生混乱,这是非常重要的,然后一些非常重要的红石线, 他将在你想的时候发送信息 (但是导线越长,越容易出错). 这些线包括红石粉红石中继器 (因为它会延长),接着到达目的地,接收器可以是一个单脉冲连接到满是红石中继器的房间里,最后再通过红石火把显示给你消息。

电报机构成

发射装置

Sending Device - Switch

在电报室的拉杆

发射装置是用来传输到接收器的一系列脉冲机制,他可以是拉杆、按钮或压力板

拉杆

拉杆在现在的所有的发射装置中最常见的,在任何情况下是最实用的选择,他可以创建一个短或长的脉冲,并是目前为止表示最准确的。

按钮

按钮可以用在One-Way电报系统中,给其他玩家发送遇险信号,可是,接收机在按键自按下去到弹回来的0.9秒之内不会被激活。 在紧急情况时,送一个遇险信号是个不错的主意。但接收器有可能会忽略通过按钮发出来的消息

压力板

虽然他们类似于按钮,但由于他们独有的特性,当生物走上去时将会激活,多个压力板可以定位一个山洞的不同点,所有这些都可以连接到One-Way(貌似译为同一个)求救电报。如果有任何怪物踩上去(只有有害怪物会在山洞里生成),只要踩上,就会发出求救信号,让其他玩家能够采取行动

接收器

Redstone Repeater - Receiver

一个用红石中继器做的6bit接收器.

接收器则是显示另一个电报室发送的信息,他可以是红石火把和红石中继器

红石火把

红石火把是一种原始但小巧的接收器,因为它可以显示从脉冲激活到接收器的过程。他不会记录、循环,或显示整条消息,但不能容易地解释一个没有清楚传送的消息。这是常见的One-Way和经典的电报系统,简单和瞬时观看是它的特点。此外,他是唯一一个能够安装在墙上的接收器。

红石灯

红石灯在1.2加入之后减少了不少麻烦,可以不需要一个非门

红石中继器

红石中继器最简单的形式是像红石火把那样接收。然而他们不能够接收快速脉冲和安装在墙壁上。当你放置两个或两个以上的中继器,可以查看消息大部分,如果够长,将可以查看整段消息,每个脉冲的显示和消失,可以调整中继器的延迟做决定,也可以让消息在接收方无限循环

活塞

你可以使用多个比特接收器,让他们看起来像点和破折号

音符盒

当加上一个反着的快速脉冲发生器,注意,他可以作为一个听觉装置并显示消息(加上快速脉冲发生器是因为可以让点和破折号分开)

信息显示器

使用信息显示器,就可以查看即将发送,然后再发送它到目的地,无论红石火把或红石中继器都可以用,当使用串联中继器,可以升级到有循环和擦出功能的显示器。

显示循环和擦除设备

Loop and Eraser - Receiver

带有循环和擦出设备的12bit接收机

循环对于显示器和接收器都是一个有用的补助,它连接端的红石中继器显示器开头,一次又一次,直到消息被删除。擦除设备是很有必要的,创建一个显示屏循环,当他们清除循环的消息,消息就被清除了。一个完整的循环系统和橡皮擦系统需要或非门(NOR)

擦除设备

它工作原理很简单:终止循环。通常,它是连接到或非门(NOR)上的拉杆。尽管他们之间有额外的空间,应建立接收器循环,并让输入端在NOR的侧边上,请记住,不应该有任何交叉的地方,当然你也可以使用多层电路。

或非门

Logic NOT

或非门可以控制循环,直到你想发送、编辑和删除消息,你需要两个拉回来的拉杆来激活它们。之后可以都向前,也可以一个向前一个向后

电报类型

One-Way 电报

One-Way Telegraph - Schematic

One-Way Telegraph - Mine Wall

Example of One-Way Telegraph Use.

As indicated by the name, messages created in a one-way telegraph may only be sent in one direction, greatly limiting its capabilities. The schematic shown demonstrates a short configuration, complete with the required sender (1), inverter (2), wiring (3) and receiver (4). However, it is the only kind of telegraph with any real practicality in single player. If one were to have the sender in a mine, and the receiver in their house, they could effectively use it like a post-it stamp, leaving a message in their house to remind them, for example, that there was diamond in that mine. Expanding on this idea, they could have a series of redstone torches in their home indicating which of their mines had diamond or some other valuable element. Whenever another mine was discovered to have this element, they could simply flip a switch, and the mine's corresponding torch would activate in the house. An example of this is shown on the left. Another use would be as a simple distress signal in multiplayer, as it is always an issue of having to simultaneously type your call for help and run away from whatever is troubling you.

基本电报

Classic Telegraph-Room

Classic Telegraph-Schematic

A two-way telegraph with control rooms on both sides.

The most basic system, the classic telegraph is quite easy to build, but not so easy to use. It consists of one lever, one inverter, and one redstone torch for each direction of communication. The schematic of a simple two-way telegraph is shown on the right. 1 and 2 are small control rooms, and A and B are inverters. Note that the area in between the two inverters can be elongated, with appropriately spaced redstone repeaters. The classic telegraph allows for a speedy construction and a space as small as 1x2x2 for each control room. In addition, due to its limited size and capability, it requires little to no knowledge of logic gates or circuitry, making it ideal for beginners or when you're low on redstone. The downside is that while you may be new to Minecraft, you have to be remarkably fluent in whatever language you decide to send the telegram in. This goes for the receiving party as well. In fact, they must begin reading the message the instant you begin sending it, or risk losing its meaning entirely. This quickly becomes problematic, especially when the server is lagging. Despite this, players use it anyway, often because they enjoy the great similarity it holds to real telegraphs. So while the classic telegraph is compact, simple, and highly realistic, it may be worthwhile to look into a more advanced system.

多向电报

Three-Way Telegraph - Room

Although the classification spans most telegraph types, the multi-directional telegraph is quite unique in its general design, and can be challenging to configure. This is mainly due to the amount of wiring required, and, in turn, the amount of space needed. For instance, a three direction telegraph requires a minimum of six separate lengths of wire, and that's just to create a classic one-torch receiver system, with no additional capabilities. While this is less of a problem over short distances, acquiring the massive quantities of redstone needed for such a project can be problematic, and it is good practice to make a rough estimate of how much you'll need before beginning its construction.
