A kind of novel electron technology experiment system based on MCU

Technical field

It the utility model is related to a kind of Experiment of Electronic Technology system, more particularly to a kind of novel electron technology based on MCU Experimental system.

Background technology

As the basis of Electronics Technology Practice Teaching, domestic and international many colleges and universities have carried out deep grind to Experiment of Electronic Technology Study carefully and explore, also reformed and adjusted accordingly.Many colleges and universities by buy set of Experiment of Electronic Technology system come Meeting the needs of Experimental Hardware, early stage is also once commercially crossed finished product experimental box in my school, but through examination after a while With, it has been found that existing Experiment of Electronic Technology system mainly emphasize function it is comprehensive, experimental problem purpose diversity can be done, Few experimental systems for strengthening students ' analysis circuit, searching fault.Student is during testing when running into It is usually helpless, have no way of doing it, do not know how solve the problems, such as to run into during problem, by the communication with student and to it The investigation of its colleges and universities, it has been found that：

Although electronic technology chip model is numerous, it is limited to laboratory condition, while is easy to manage, laboratory is general The chip limitednumber of offer, corresponding student's design is also restrained, so causes student to be disinclined to beat one's brains, copy mutually Attack.If experimental system hardware has the function of setting trouble point, so that it may accomplish that a people one inscribes, the process of trouble-shooting point just as Precious process is sought, student's ratio is relatively interesting, can drastically increase student and do the enthusiasm tested.

2. often occur the mistakes and errors that some students often violate during Experiment of Electronic Technology, sometimes this mistake It is typical and universal, student usually delays substantial amounts of experimental period because mistake is searched, if that can set failure The Experiment of Electronic Technology system of point, contributes to student to deepen the impression, the same mistake of the criminal of avoiding by artificial this failure of simulation By mistake, energy is put into the design and analysis of circuit.

The use of conventional electronic measuring instrument is the basic skills that student should grasp, but at this stage to instrument Study and use scattered, single, few topics that various instruments can be comprehensively utilized with training student.If can be with The Experiment of Electronic Technology system of trouble point is set, and by deliberately setting some glitch, student can be learnt with task The use of instrument, so it is capable of the use range and advantage and disadvantage of more various measuring instruments, selection and use of the student to instrument Just can more efficiently and effect.

The content of the invention

The purpose of this utility model is aiming at drawbacks described above existing for prior art, there is provided a kind of based on the new of MCU Experiment of Electronic Technology system, by increasing microcontroller and wireless module, realize that trouble point sets and monitored work(using host computer Can, realize the intellectuality of Experiment of Electronic Technology system.

Its technical scheme is：Including microcontroller, failure of chip setup module, power failure setup module, input and output Failure setup module, wireless communication module, the microcontroller use the single-chip microcomputer with analog signal and data signal C8051F120, microcontroller connect failure of chip setup module, power failure setup module, input and output failure and set respectively Module and wireless communication module, wherein, failure of chip setup module, power failure setup module and input and output failure set mould The action for the I/O control relays that block passes through microcontroller, realizes the break-make of signal and the switching of circuit, with this analog circuit The loose contact of the wire and chip of appearance；In addition, gathering the information of trouble point by A/D, realized and learned by wireless communication module The monitoring of raw experimentation.

Wireless communication module is made up of two parts, when collection and the emitter of signal, by sensor and SRWF-501 Integrated circuit modules are formed；Second, the reception of signal, measurement and control device, by SRWF-501 integrated circuit modules and upper Server end is formed, and SRWF-501 integrated circuit modules are connected by three leads with single-chip microcomputer C8051F120, single-chip microcomputer C8051F120 realizes the reception and transmission of the data between SRWF-501 by two interfaces of RXD and TXD, belongs to half-duplex and leads to Letter mode.

SRWF-501 is connected by other three leads with the serial ports of PC, and PC realizes data by the RX and TX of serial ports Reception and transmission, belong to half-duplex operation mode.

Serial port baud rate is all set to 9600 between single-chip microcomputer and microcomputer.

SRWF-501 is a kind of chip of monolithic wireless receiving and dispatching one, there is provided the connector of 19 pin, SRWF-501 bags High-frequency emission, high-frequency reception, PLL synthesis and multichannel switching circuit are contained.

The beneficial effects of the utility model are：By increasing microcontroller and wireless module, failure is realized using host computer Point is set and monitoring function, realizes the intellectuality of Experiment of Electronic Technology system.Using this improved experiment porch, except can To carry out outside normal experiment, it is most important that by the distal end setting of trouble point and monitoring function, make the function of Experimental Hardware rich Become better-off, the process picture of student's debugging seeks the process of treasured, and learning interest is denseer, and enthusiasm is higher.Student tests simultaneously Transparent procedures get up, teacher can do the progress tested by students ' in real time, can find that student is done in experimentation at any time The problem of exposing, so it is more conducive to improve experimental teaching from now on.

Set with trouble point and the smart electronics experimental system of monitoring function is a kind of brand-new experimental system, removed Outside basic Experiment of Electronic Technology, at present using new experimental system as hardware foundation, it is multinomial that new experimental project 10 is designed in exploitation, In each experiment, though experiment topic is identical, Experimental Hardware outward appearance is identical, and experimental system function is set by distal end Afterwards, the hardware case of each student is different that can so be effectively prevented from student's plagiarism, and the evaluation and examination to student are more What is added is objective.
