Briefly describe the basic requirements of computer control system design

1. The basics of control system design Principle: The system has good operation performance, easy to use and easy to maintain. High reliability. It is versatile and easy to expand. Strong real-time, which is reflected in time-driven and time-driven ability.The design cycle is short and the price is cheap.

2. The purpose of control can be to make the state or movement process of the accused object meet certain requirements, or to achieve some optimization goals.

3. Divide the software and hardware functions of the system. In addition, in the design of microcomputer control system, the selection of control algorithm should meet the requirements of system control speed, control accuracy and system stability. A variety of control algorithms can be designed in the control system, and the best control algorithm can be selected through digital simulation or experiment analysis and comparison.

4. [Answer]: The general design content of the computer control system is as follows. 1 Analyze the process characteristics and requirements of the accused object, and formulate the control functions and design objectives of the control system. 2 Refine the technical requirements of the control system, such as the number of I/O interfaces, system structure form, physical location of installation, etc.

Principles of system design

1,. The principle of autonomy and controllability. Network security and confidentiality are related to the sovereignty and security of a country, so network security products cannot rely on foreign products. 7. The principle of safety and value. The design of the network system is limited by funds.

2. The overall design of the system should be based on the design idea of the system engineering, so that the developed system can meet the overall requirements of science, rationalization and economy. Generally, the following basic principles are followed.

3. The principle of flexibility and variability. Flexibility refers to the ability of the system to adapt to changes in the external environment. Whether a system can play a role and have strong vitality depends to a large extent on whether it is acceptable to management.

4. Feasibility principle The feasibility principle refers to the fact that in the process of logistics system planning and design, each planning element must meet the established resource constraints. That is to say, the planning and design of the logistics system must take into account the existing disposable resources and must conform to its own actual situation, whether from the technical Above, it can still be achieved economically.

5. In the practice of system design, these two methods are often used together. Phase development principle The system framework and data structure are comprehensively designed, and the specific functions are realized in stages.

6. Comprehensive principle: The design of mechatronics system needs to consider many factors such as mechanical, electrical, electronic and computer to ensure the comprehensiveness of the system.

Roof planting system design methods and key points

1. Plant selection and matching plants should adapt to local climatic conditions and the height of the planting roof. It is appropriate to choose shallow-rooted plants that are heat-resistant, cold-resistant, drought-resistant, barren-resistant and coarsely managed. According to landscape requirements, it should be matched with slow-growing trees, shrubs, Fujimoto and an appropriate amount of garden and architectural sketches.

2. The roof design should leave 0m~5m space around the vent or other equipment for later overhaul. The roof design planted around the air conditioner or kitchen hood should consider decorative cover to avoid the plant being killed by the dry and hot wind. Leisure facilities such as vine racks, pavilions or sun rooms should pay special attention to windproof and stability in the roof design.

3. In fact, when designing a garden on the roof, it is necessary to do a good job of prevention.The work of water, this is because if the roof is to be made into a garden, it needs to produce a lot of moisture every day. At this time, if the drainage system of the roof is not good, it will make the roof in a damp state.

What principles should be followed when designing a performance management system

1. The principle of goal consistency: The design of the performance management system should be consistent with the company's strategic goals and business needs to ensure the performance of employees The standard is consistent with the overall goals of the company and can make a targeted evaluation of the performance of employees.

2. The design of the performance management system should follow the following principles: goal-oriented principle: the performance management system should be in line with the enterprise strategyConsistently, performance evaluation indicators should be linked to enterprise goals and work plans to ensure that performance evaluation goals are clear, measurable and actionable.

3. The following principles should be followed when designing a performance management system: (1) The principle of openness. All standards and processes of performance management are clearly stipulated in the form of a system, and a certain organization, time, method and standards are formed within the company, which is convenient for the assessor and the assessee to operate in accordance with standardized procedures. , to ensure the fairness of the procedure.

4. Performance management can usually be based on the following five design principles: Goal-oriented: Performance management should be oriented by clear goals, including expectations and goals for individual employees, teams and organizations.

5. [Answer]: B, C, D performance testThe establishment of the evaluation index system is an important premise and basic guarantee for effectively organizing performance evaluation and achieving the goals and requirements of enterprise performance management.

6. When designing a performance appraisal index system, multiple principles can be used to ensure the effectiveness, fairness and feasibility of the system. The following are some main principles: clear alignment with strategic goals: ensure that performance appraisal indicators are closely aligned with the company's strategic goals and business needs, and the performance goals of employees should be consistent with the overall goals of the company.
