How does PLC control the water level of the water tower?

1. Water tower water level automatic control plc program diagram: Trapezoidal diagram programming language is a graphical programming language. It follows the terms and graphic symbols such as contacts, coils, series and parallel connections in the traditional relay contactor control, which is very similar to the traditional relay control principle circuit diagram, but also adds There are many powerful and flexible commands.

2. Automatically control the water level in the water tower through the switch of the water pump. When the PLC fails, there is also a set of manual control to control the water level of the water tower. AC contactor is used for manual control.

3. Valve Y is closed (Y is OFF). When S4 is OFF, and the water level of the water tower is lower than the low water level of the water tower, S2 is ON, and the motor M operates to pump water.When the water level of the water tower is higher than the high water level of the water tower, S1 is ON, the motor M stops, and the valve X automatically opens the drainage. When the water level is lower than S2, the valve X stops. The motor M began to start pumping water again and ran like this.

4. The microcomputer control data processing part makes full use of the role of the existing port of 8031 in the circuit design, and also considers expansion to save components as much as possible, which can not only reduce costs, but also improve reliability. ( 1) Use 8031 single-chip microcomputer. The circuit of water tower water level control is shown in Figure 3-1.

How to draw the water tower water level automatic control plc program diagram?

Water tower water level automatic control plc program diagram: trapezoid diagram programming language is a kind of graphical compilationProcess language, it follows the terms and graphic symbols of contacts, coils, series and parallels in the traditional relay contactor control, which is very similar to the traditional relay control principle circuit diagram, but adds many powerful and flexible instructions.

Automatically control the water level in the water tower through the switch of the water pump. When the PLC fails, there is also a set of manual control to control the water level of the water tower. AC contactor is used for manual control.

What do you do? I have a friend in Siemens. I can introduce him to you.

Control requirements (take Mitsubishi FX series PLC as an example) The water tower water level automatic control module hanging box is shown in the figure.

Pump water into the water tower; when the STOP button X3 is pressed, or the water storage in the tower is higher than the upper water level (high water level detection photoelectric X1), the water pump motor stops pumping.

Find the shortcomings of the plc water tower water level control system.

1. Hello, PLC is a programmable controller, which is a control system of the water level of the water tower; it is necessary to have multiple pumps to supply water to the water in the water tower, but if there is only one water pump, several sets of contacts can be used to control the sound and light signals that are connected and reliable.

2. The equipment can also be intelligentized through many external sensors. Isn't it good for you to take something seriously, do it well, and improve your ability and knowledge? Think about it again. How to make the water tower control system intelligent.

3. The water level of the water tower isDynamic control plc program diagram: Trapezoidal diagram programming language is a graphical programming language. It follows the terms and graphic symbols of contacts, coils, series and parallel connections in traditional relay contact control, which is very similar to the traditional relay control principle circuit diagram, but adds many powerful and flexible instructions. .

What does the intelligentization of the plc water tower water level control system mean?

Automated control cannot be regarded as intelligent. Smart devices need to have automatic adjustment ability to be considered intelligent. It's like people drink boiled water when they wait for the water temperature to drop. The equipment can also be intelligentized through many external sensors.

Realize automatic control and improve the operation efficiency and safety of the water tank. Purpose: The purpose of plc water tank water level control is to realize automatic control and save manpower and time costs. Significance: The significance of plc water tank water level control is to improve the operation efficiency and safety of the water tank and create a good industrial environment.

PLC (power carrier communication technology) control is one of the main control methods in smart home. It has high reliability, fast response speed, securityWith the advantages of strong and easy maintenance, by embedding PLC equipment into home equipment, smart home control can be realized more stably and conveniently.

How to control the water level of the water tower with PLC?

Water tower water level automatic control plc program diagram: Trapezoidal diagram programming language is a graphical programming language, which follows the terms and graphic symbols of contacts, coils, series and parallel connection in the traditional relay contactor control, which is very similar to the traditional relay control principle circuit diagram, but adds Xu Multi-functional and flexible instructions.

Now when the 1# pump is running, press the start button SB2, and the 2# pump starts to pour water into the water tower. At this time, the water level light on the console is from the water tower.The liquid level transmitter converts the water level into a 4~20mA current signal and inputs it into the PLC, and converts it into a digital signal through IDPG.

When the water level of the pool is lower than the low water level of the pool (S4 is ON), the valve Y turns on the water inlet (Y is ON) and the timer starts timing. After 4 seconds, if S4 is not OFF, the valve Y indicator light flashes, indicating that there is no water in the valve Y and there is a fault. After S3 is ON, the valve Y is turned off. Close (Y is OFF).
