Problems solved by technology

[0002] The main disadvantages of the existing automatic control theory experiment box are: 1. The experiment box focuses on the understanding of the basic concepts of automatic control theory, and does not reflect the parameter adjustment and control effect of the actual automatic control system
2. The experimental box can only complete the experiment by receiving the analog signal generated by the computer software through a wired method, and the experimental box itself has no signal source and cannot complete the experiment independently of the computer. This requires the stability of the transmission interface between the computer and the experimental box. Very high, the connection is inconvenient, once the transmission interface fails, the experiment cannot be completed
3. The main problem of the current experimental box used in experimental teaching is that the entire experimental instrument cannot work due to the damage of the transmission interface, and the maintainability is very poor.
4. The transmission between the experimental box and the computer adopts RS232 serial port transmission, the data transmission rate is low, and the connection is inconvenient, which can no longer meet the requirements of data collection and transmission in the current automatic control theory experiment
5. The experimental box is not conducive to the interaction between teachers and students in the experiment
6. The experiments in the existing experimental box are not intuitive enough for the understanding of automatic control theory

Abstract

The invention relates to a teaching and experiment instrument of an automatic control theory, belonging to the technical field of teaching and experiment instruments. The instrument is additionally provided with a signal source module, a wireless communication module, a temperature control and perception module, simulation experiment control software, and the like. The instrument has the advantages that a one machine controls a plurality of instruments, or a plurality of machines control an instrument to finish all kinds of teaching experiments of the automatic control theory through an external computer by adopting a wireless way, thereby increasing the teacher-student interaction ability and the teaching demonstration function; the adopted simulation experiment control software can be independent of interment hardware to finish various simulation teaching experiments of the automatic control theory and compare the difference of the theory and the practical laboratory data to grasp the difference of the engineering practice and the theory; separating from the cooperation of the computer or the simulation software, the hardware of the instrument can finish various teaching experiments of the automatic control theory independently, thereby ensuring the flexibility of the experiment; the software and the hardware of the instrument are combined to finish various teaching experiments of the automatic control theory, and the software and the hardware depend on and combines with each other to increase the reliability and the convenience of the experiment. The teaching and experiment instrument of the automatic control theory is a regeneration product and is worthy of adoption and generalization.
