The digital temperature detector is one of single-chip microcomputer Related product common in " Fundamentals of Mono-Chip Computers and application thereof " teaching; But the existing most of internal hardware circuit of digital temperature detector that are used to impart knowledge to students have welded fixing complete product; Teacher is difficult to respectively to form module with telling about in detail for students under the circuit tear-down in the teaching process of single-chip microcomputer; The assembling process of demonstration digital temperature detector each several part, for the lower student of a lot of beginners or understandability owing to do not have actual participation or sense of reality Products Development process indigestion.The student also has no idea to do it yourself in the hands-on link to make up and debug circuit.

Summary of the invention

The purpose of the utility model provides a kind of module combined type digital temperature detector that is used for single chip computer teaching; Solve existing teaching and welded fixingly with digital temperature detector hardware circuit, be difficult to dismantle the problem that circuit and life can't oneself be built circuit, made up product that re-assemblies.

The technical scheme that the utility model adopts is; A kind of module combined type digital temperature detector that is used for single chip computer teaching; Include the core cpu module; The core cpu module through the jack line successively with digital-to-analogue/analog-to-digital conversion module, input-output device module commonly used on temperature detecting module and the switch module on the Keysheet module is connected, the core cpu module is connected with running lamp/dynamic digital tube module through winding displacement, bus is expanded and driver module is connected on the core cpu module through the jack line; The core cpu module is provided with power module, and whole device relies on the power module power supply that is provided with on the core cpu module.

The characteristics of the utility model also are,

Digital-to-analogue/analog-to-digital conversion module comprises analog-to-digital conversion module and DAC0832 D/A converter module of a 5V regulated power supply module, an ADC0809;

Power module is by the conventional dc power supply power supply of independent 5V ~ 12V or through the USB interface power supply;

Running lamp/dynamic digital tube module comprises common positive LED lamp module, is total to cloudy LED lamp module and dynamic digital tube module;

Bus expansion and driver module comprise 74LS138,74L S245 and three parts of 74LS373;

The beneficial effect of the utility model is; The module combined type digital temperature detector that the utility model is used for single chip computer teaching adopts modular design concept; Circuit module by a plurality of standalone features is formed through winding displacement or plug wire hole, can make up the principle model of actual industrial product through composite module.The present invention is particularly suitable for the beginner; Make the student can very clearly be familiar with the composition of a scm application system; In experiment, real standard process, the student can do it yourself to carry out the similar principle of operation that plays with building blocks according to the own knowledge of being grasped; With making up between each module, accomplish ultimate system is used.This equipment has good durability, and is not fragile; Dismounting back advantages of small volume is easy to carry; The extensibility of equipment is good, at present with enough be main, later on as required, can increase corresponding complex modules, the student also can expand the system of oneself based on this, accomplishes the practice to expanding system.For the teacher implements guide type teaching, on-the-spot teaching etc. suitable teaching aid is provided, also can have made the student utilize this equipment to accomplish the contents of courses such as the experiment of course, real standard and Course Exercise simultaneously, fully grasped content.Finally solve problems such as teacher does not have teaching aid in teaching process, and the student does not have material, and the content of courses is empty, and real standard is insubstantial.This modular single-chip microcomputer has certain booster action to teacher's teaching, and the practical training to the student also is the raising process of a ladder property simultaneously, has excellent popularization and is worth.
