Electrical control principle circuit design methods mainly include analysis design method and logic design method.
1. Analytical design method
The analytical design method selects the appropriate basic control links (unit circuits) according to the requirements of the production process or combines the more mature circuits according to their interlocking conditions, and supplements and modifies them into a complete circuit that meets the control requirements. When there is no typical link that is ready, the edge design can be analyzed according to the control requirements.
The advantage of the analytical design method is that the design method is simple and there is no fixed design procedure. It is based on the basics of various electrical control circuits and the ability to read and analyze the electrical control circuit. It is easy for beginners to master. For electrical technicians with certain work experience, the design task can be completed quickly, so it is widely used in electrical design; the disadvantage is that the designed solution is not necessarily the best solution, when the experience is insufficient or not considered Weektime will affect the reliability of the line work. To this end, the circuit should be reviewed repeatedly. If there are conditions, the simulation test should be carried out, and the problem should be corrected in time until the circuit action is correct and the production process requirements are met.
2, logic design method
The logic design method uses logic algebra to design the circuit. Starting from the dragging requirements and process requirements of the production machinery, the contactor and relay coils in the control circuit are energized and de-energized, and the contacts are closed and disconnected. The turn-on and turn-off of electrical appliances are regarded as logical variables, and the relationship between them is expressed in a logical relationship according to the control requirements, and then simplified, and the corresponding circuit diagram is made.
The advantage of the logic design method is that it can obtain an ideal and economical solution. However, this method is difficult to design, the whole design process is more complicated, and some new concepts are involved. Therefore, in the general conventional design, it is rarely used alone.
