Description

The opening Experiment of Electronic Technology platform of combined type

Technical field

The opening Experiment of Electronic Technology relatives of Taiwan compatriots living on the Mainland of combined type relate to a kind of electronic technology practical training experiment table in electronic technology field.

Background technology

The experimental facilities that Experiment of Electronic Technology is relevant has had the development course of decades, though the equipment that numerous manufacturer produced is of a great variety, form is different, but all comparing class is seemingly for their characteristics, fixing power supply, signal source, bread breadboard or special-purpose experimental circuit template promptly is provided, is installed in the fixing experimental box.Though some experimental box also adopts modular form, can select configuration, fixing because of its functions of modules, can only carry out replication experiment.The advantage of traditional experiment case is that function is integrated, and that module is fixed, installed is firm, be convenient to management, therefore plays an important role in experimental teaching.The subject matter that the traditional experiment case exists is as follows:

1,, can only finish some relatively more fixing experiments according to the existence conditions that experimental box provides because experimental box has been made fixing pattern, and the performance space of leaving the experimenter for is very little.The student can only do some simple settings to specifications and overlap joint just can be finished hardware composing, is unfavorable for cultivating open thinking of student and creativity consciousness.

2, the teaching system that can not be fit to vary with each individual owing to the public property of experimental box, will be received different students usually in a short time and finish experiment, so the circuit of front student overlap joint will be removed after class.If (in two kinds of situation: student ability is poor in the experiment that the student fails to finish in official hour, content/the student ability that can not finish regulation is strong, finish the content that more choosing is done or intend certainly), want to utilize the open hour to continue experiment after finishing this class hour, the circuit of just must pegging graft once more, this is undoubtedly a kind of way of poor efficiency.

3, can't realize linking between the experiment module, lack systematicness.Each experiment course all includes a plurality of experiments, usually connects each other between the experiment content, all comes down in a continuous line as power supply, signal generation, signal amplification, filtering, the power amplification of analogous circuit experiment.Form a complete contact, just require to keep the circuit of each experiment, realize uniting and adjustment at last.Obviously traditional experimental box can't be accomplished this point.

Summary of the invention

In order to address the above problem, the utility model provides a kind of and can conveniently plug and the electronic technology of debug function module is provided with platform, and the functional module substrate of standard is provided, and has made things convenient for the making and the debugging of functional module.

To achieve these goals, the utility model has designed the opening Experiment of Electronic Technology platform of a cover combined type, comprises main platform and functional module substrate.Described main platform comprises front plate zone and side panel zone, wherein the front plate zone also is divided into power supply IO interface zone, simulating signal IO interface zone, digital signal input zone, functional module socket region, and the side panel zone comprises supply socket, power switch, Insurance Block, external function tool interface system; Described functional module socket region is made up of nine groups of identic spininess sockets, and except that one group of socket as the power supply function module is connected to the transformer, all the other eight groups all general.Nine groups of sockets and power supply IO interface, simulating signal IO interface, all by interconnecting with bus form in the motherboard, the external function tool interface system is also received the bus in the motherboard to digital signal input.Described functional module substrate is the mesh plate that is provided with the plug corresponding with the functional module socket.

Described each functional module socket is made up of one 26 spring hole scoket and one 34 spring hole scoket; Described external function tool interface system is made up of one 25 hole D shape socket and one 37 hole D shape socket, and is connected with 34 spring hole scokets with 26 spring hole scokets of each functional module socket.

Also be provided with red, green, yellow three pilot lamp in the zone of the socket of described power supply function module, the working condition of indication power supply function module.

Power module, signal source module, digital circuit debugging module, microcomputer development plate and bread board module on ready-made the be plugged on functional module socket also have been equipped with in this experiment table.

The major advantage of this device is:

1, adopt the structure of plug-in template, template can be installed on the main platform with the mode of plug, realizes the connection of signal by the pin-hole interface of standard.Main platform is only established the motherboard that bus connects, and other experimental circuit can be used template construct, has greatly expanded the space of experiment content autonomous innovation.And template adopts mesh plate as substrate, by experimenter oneself the circuit that designs welded out, is plugged on the experiment table and debugs.For teaching, on levying, the student can not finish when making, and can take away under the class and finish.Like this, neither influence the back classmate on class, also can keep being fruitful of oneself.Simultaneously, the circuit of a plurality of experiments of oneself can keep always, is convenient to realize the uniting and adjustment of a plurality of functional circuits, helps cultivating the theory of students system design.

2,, the advantage that can break away from common apparatus (as power supply, signal source etc.) unit work integrated for inheriting tradition experimental box function, this experiment table can also dispose as power module, signal source module, digital circuit debugging module and bread board module etc.All adopt the form of plug connector, need or not just to tear open with regard to usefulness, flexible configuration is convenient to maintenance.
