A. 水泵自動液位控制器的問題
下面從圖(一部分控制電路)分析。
S3是停止按鈕。S2-1接通是手動狀態,S4按鈕按下專,KM接觸器線圈得電,屬KM的常開觸點自鎖,水泵電機運行;S2-2接通是自動狀態,K1這里(接自動液位控制器)接通,KM接觸器線圈得電,水泵電機運行。
我們來分析KI的通斷狀態,通則水泵電機運行,斷則水泵電機。我們可以看成KI左接自動液位控制器的一根線,另外自動液位控制器的另一根線接KI右。當水位不到不抽水,它是垂直的,此時自動液位控制器接入自動這里的狀態是斷開的。等水位升起後自動液位控制器浮起,它的內部有一個小球把觸點接通就開始抽水。水位落下,小球滾到另一頭,觸電斷開,就停止抽水,如此反復。
自動液位控制器你把它豎起,你用萬用表量自動液位控制器的任意兩根線,如果是斷開狀態。你把自動液位控制器再反方向,它是接通狀態。你就把這兩根線接入圖的K1處。
你檢查自動液位控制器的好壞在送電手柄打自動的情況下,你放下自動液位控制器電機停止,你把自動液位控制器倒過來電機運行,這樣來確認。另外就是用表量了。

Microcontrollers
A microcontroller is an integrated circuit (IC) that is programmable. When you turn on the power to the microcontroller it goes through a series of commands. These commands are put in the chip by you. You can make it do different things by changing the commands (usually called the program). To change the commands you need a device like the PG302. The PG302 lets you download the program from your computer to the microcontroller. This chapter will show you some simple programs and how to download those to
2.0.1The 555 Timer
Creating a Pulse
The 555 is made out of simple transistors that are about the same as on / off switches. They do not have any sense of time. When you apply a voltage they turn on and when you take away the voltage they turn off. So by itself, the 555 can not create a pulse. The way the pulse is created is by using some components in a circuit attached to the 555 (see the circuit below). This circuit is made of a capacitor and a resistor. We can flip a switch and start charging the capacitor. The resistor is used to control how fast the capacitor charges. The bigger the resistance, the longer it takes to charge the capacitor. The voltage in the capacitor can then be used as an input to another switch. Since the voltage starts at 0, nothing happens to the second switch. But eventually the capacitor will charge up to some point where the second switch comes on.
The way the 555 timer works is that when you flip the first switch, the Output pin goes to Vcc (the positive power supply voltage) and starts charging the capacitor. When the capacitor voltage gets to 2/3 Vcc (that is Vcc * 2/3) the second switch turns on which makes the output go to 0 volts.
The pinout for the 555 timer is shown below
Deep Details
Pin 2 (Trigger) is the 'on' switch for the pulse. The line over the word Trigger tells us that the voltage levels are the opposite of what you would normally expect. To turn the switch on you apply 0 volts to pin 2. The technical term for this opposite behavior is 'Active Low'. It is common to see this 'Active Low' behavior for IC inputs because of the inverting nature of transistor circuits like we saw in the LED and Transistor Tutorial.
Pin 6 is the off switch for the pulse. We connect the positive side of the capacitor to this pin and the negative side of the capacitor to ground. When Pin 2 (Trigger) is at Vcc, the 555 holds Pin 7 at 0 volts (Note the inverted voltage). When Pin 2 goes to 0 volts, the 555 stops holding Pin 7 at 0 volts. Then the capacitor starts charging. The capacitor is charged through a resistor connected to Vcc. The current starts flowing into the capacitor, and the voltage in the capacitor starts to increase.
Pin 3 is the output (where the actual pulse comes out). The voltage on this pin starts at 0 volts. When 0 volts is applied to the trigger (Pin 2), the 555 puts out Vcc on Pin 3 and holds it at Vcc until Pin 6 reaches 2/3 of Vcc (that is Vcc * 2/3). Then the 555 pulls the voltage at Pin 3 to ground and you have created a pulse. (Again notice the inverting action.) The voltage on Pin 7 is also pulled to ground, connecting the capacitor to ground and discharging it.
Seeing the pulse
To see the pulse we will use an LED connected to the 555 output, Pin 3. When the output is 0 volts the LED will be off. When the output is Vcc the LED will be on.
Building the Circuit
Place the 555 across the middle line of the breadboard so that 4 pins are on one side and 4 pins are on the other side. (You may need to bend the pins in a little so they will go in the holes.) Leave the power disconnected until you finish building the circuit. The diagram above shows how the pins on the 555 are numbered. You can find pin 1 by looking for the half circle in the end of the chip. Sometimes instead of a half circle, there will be a dot or shallow hole by pin 1.
Before you start building the circuit, use jumper wires to connect the red and blue power rows to the red and blue power rows on the other side of the board. Then you will be able to easily reach Vcc and Ground lines from both sides of the board. (If the wires are too short, use two wires joined together in a row of holes for the positive power (Vcc) and two wires joined together in a different row of holes for the ground.)
Connect Pin 1 to ground.
Connect Pin 8 to Vcc.
Connect Pin 4 to Vcc.
Connect the positive leg of the LED to a 330 ohm resistor and connect the negative end of the LED to ground. Connect the other leg of the 330 ohm resistor to the output, Pin 3.
Connect Pin 7 to Vcc with a 10k resistor (RA = 10K).
Connect Pin 7 to Pin 6 with a jumper wire.
Connect Pin 6 to the positive leg of the 220uF Capacitor (C = 220uF). (You will need to bend the positive (long leg) up and out some so that the negative leg can go in the breadboard.
Connect the negative leg of the capacitor to ground.
Connect a wire to Pin 2 to use as the trigger. Start with Pin 2 connected to Vcc.
Now connect the power. The LED will come on and stay on for about 2 seconds. Remove the wire connected to Pin 2 from Vcc. You should be able to trigger the 555 again by touching the wire connected to pin 2 with your finger or by connecting it to ground and removing it. (It should be about a 2 second pulse.)
Making it Oscillate
Next we will make the LED flash continually without having to trigger it. We will hook up the 555 so that it triggers itself. The way this works is that we add in a resistor between the capacitor and the discharge pin, Pin 7. Now, the capacitor will charge up (through RA and RB) and when it reaches 2/3 Vcc, Pin 3 and Pin 7 will go to ground. But the capacitor can not discharge immediately because of RB. It takes some time for the charge to drain through RB. The more resistance RB has, the longer it takes to discharge. The time it takes to discharge the capacitor will be the time the LED is off.
To trigger the 555 again, we connect Pin 6 to the trigger (Pin 2). As the capacitor is discharging, the voltage in the capacitor gets lower and lower. When it gets down to 1/3 Vcc this triggers Pin 2 causing Pin 3 to go to Vcc and the LED to come on. The 555 disconnects Pin 7 from ground, and the capacitor starts to charge up again through RA and RB.
To build this circuit from the previous circuit, do the following.
Disconnect the power.
Take out the jumper wire between Pin 6 and Pin 7 and replace it with a 2.2k resistor (RB = 2.2K).
Use the jumper wire at pin 2 to connect Pin 2 to Pin 6.
Now reconnect the power and the LED should flash forever (as long as you pay your electricity bill).
Experiment with different resistor values of RA and RB to see how it changes the length of time that the LED flashes. (You are changing the amount of time that it takes for the Capacitor to charge and discharge.)
第2章微控制器
微控制器是一個可編程集成電路(IC),當你開啟微控制器時就會看到一系列的命令,這些命令是你事先植入晶元中的。你可以通過改變這些命令做不同的事情(通常稱為編程)。為了修改你的命令你需要一個PG320這樣的裝置,你可以通過PG320從計算機上下載程序到微控制器上。這一章將為你展示一些簡單的程序和如何下載。
2.0.1 555定時器
如何產生脈沖
555 定時器是由簡單的晶體管組成,作用和觸發器一樣,它們本身不能定時,當你接上電源它們開始產生脈沖,當你撤掉電源它們就不能產生脈沖,所以對於555定時器本身來說不能產生脈沖。產生脈沖的方法就是用一些元件把555連接在一個電路中(如下面的電路)。這個電路是由一個電容器和一個電阻器構成的。我們可以交換觸發器和啟動充電電容。電阻器用來控制電容充電的快慢。電阻越大,電容充電時間越長。電路中的電壓可以用作輸入的另一個觸發器,因為起始電壓為0時,在第二個開關處不會有任何的反應,但最終由於電容器充電到一定值激活第二個觸發器。
555工作的原理是當你交換第一個觸發器,輸出引腳為Vcc(由陽極供應電壓),電容器開始充電。當電容器電壓達到2/3的Vcc(也就是Vcc*2/3),第二個觸發器閉合使輸出電壓為0伏。
555定時器的引出線如下:
詳細資料
引腳2(觸發器)是脈沖的啟動開關。觸發器的字元線路告訴我們電壓與我們通常所期望的相反。當引腳2接0伏電壓,對這個相反行為的專業術語稱為「低態有效」。對於IC輸入模塊看到低態有效行為很平常,因為晶體管電路的轉換實質就像我們在LED和晶體管指南看到的一樣。
引腳6是脈沖的關閉開關。我們把電容器的陽極連接到這個引腳上,電容器的陰極接地。當引腳2(觸發器)是Vcc,555定時器電壓處於0伏控制引腳7(注意反轉電壓),當引腳2電壓為0伏時555停止控制引腳7,然後電容器開始充電。電容器通過連接在Vcc上的電阻充電,電流開始流入電容器,電容器的電壓開始升高。
引腳3是輸出(在這里輸出實際的脈沖)端。引腳3上起始電壓為0,當觸發器(引腳2)上電壓為0時,555 通過Vcc控制引腳3直到引腳6電壓達到Vcc的2/3(也就是Vcc*2/3)。然後將引腳3的電壓接地,這樣你就可以看到一個脈沖(此外注意翻轉作用).引腳7上的電壓同樣也要接地,連接電容器進行地面放電。
觀看脈沖
為了看到脈沖我們用一個LED接在555輸出端(引腳3)。當輸出端電壓為0伏時LED將不工作,當輸出端是Vcc時LED將工作。
構建電路
因為555的放置要穿過電路實驗板的中間線路所以一邊4個引腳。(為了使它們放在孔中你可能需要把引腳彎曲一點)。直到完成電路後才可以通電。上面的圖表指導你怎樣將555上面的引腳編號。你可以通過尋找在晶元末端的半個循環發現以腳1。有時候不是半個循環,而是一個點或是很淺的洞。在你開始構建電路之前,用跳線連接紅或綠動力行和在電路板另一邊的紅或綠動力行。然後你會很容易的將電路板兩邊的Vcc和地線連接在一起(如果電線太短,對於陽極(Vcc)用兩個電線接在一起成一排,對於地線用兩根電線接在一起成不同的排)。
將引腳1接地.
將引腳8接到Vcc上.
將引腳4接到Vcc上.
將LED的陽極接到330歐姆的電阻器上,LED的陰極接地。將330歐姆電阻器的其它接頭連接輸出端引腳3.
將引腳7用一個10K的電阻接到Vcc上(R =10K)。
引腳7和6用跨接線連接。
引腳6接220μF的電容器陽極(C=220μF)。(為了使陰極能插進電路實驗板你可能需要將陽極(長腿的)彎進或彎出一點。
電容器的陰極接地。
引腳2用線接出作為觸發器。開始把引腳2和Vcc連接起來。
現在接電源。LED將被激活停留大約2秒。從Vcc上拔掉連接引腳2的電線,你可以通過用你手指接觸連接引腳2的電線或將電線接地或是移開來再一次激活555。(它應該產生大約2秒鍾的脈沖)
振盪
接下來我們將使LED不斷的反射而不必觸發它。我們將鉤住555以便它自己本身可以觸發。工作原理就是我們在電容器和放電引腳,引腳7之間加一個電阻。現在,電容器將充電(通過 )當電壓達到2/3 Vcc時,把引腳3和引腳7接地。但由於RB電容器不能立即放電,電容器通過RB從充電到放電需要一定的時間,RB的電阻越大時間越長。電容器開始放電的時間也就是LED工作中斷的時間。
為再一次觸發555,我們將引腳6和觸發器(引腳2)連接起來。當電容器充電時電容器內的電壓越來越低。當電壓降到1/3 Vcc時觸發器引腳2使引腳3變為Vcc並且通過LED激活555。將引腳7從地面上斷開,電容器開始通過RA和RB再次充電。
從以前的電路上構建這個電路,做法如下:
斷開電源。
去掉引腳6和引腳7之間的跨接線,用2.2K的電阻來代替(RB=2.2K)
用引腳2處的跨接線連接引腳2和引腳6。
現在重新連接電源並且LED應該始終閃爍(只要電源是開著的)。
用不同阻值的RA和RB做實驗看一下LRD閃爍時間長短的變化(你可以改變電容器充放電時間的長短)。

D. dn100消防水池給水液位控制器原理
其實就是100X隔膜式遙控浮球閥與小浮球閥配合,為水池自動供水的裝置。
100X隔膜式遙控浮球閥是閥門供應網開發生產的一種兼具多種功能的控制水池液位的水力控制閥。100X隔膜式遙控浮球閥主要安裝於水池或高架水塔的進水口處,當水位達到設定的高度時,主閥由浮球導閥控制關閉進水口停止供水;當水位下降後,主閥由浮球開關控制打開進水口向水池注水,實現自動補水。液位控制精確,不受水壓干擾;100X隔膜式遙控浮球閥可隨水池的高度及使用空間任意位置安裝,維護、調試、檢查方便、密封可靠,使用壽命長。100X隔膜式遙控浮球閥性能可靠、強度高、動作靈敏靈活適用於450mm口徑以下的管道。DN500mm口徑以上的建議使用活塞式。
工作原理:
100X遙控浮球閥利用管道上游的水壓推動閥瓣上升,開啟閥門,向水池供水;當水池液面到達所需高度時,浮球在浮力的作用下上升,從而關閉閥門,截斷管道向水池的排放。當水池排放掉水時,浮球下落,開通上腔的流通,此時,上游的壓力又使閥瓣上升,開啟閥門,使管道繼續向水池供水。遙控浮球閥,浮球動作迅速,液位控制准確度高,靈活耐用,水位不受水壓干擾且關閉緊密不漏水。遙控浮球閥主要安裝在高層建築水塔、水池的進水管道上。
