Abstract
The present invention relates to a kind of four distant experiment teaching device of hand held, it includes temperature sensor, analog switching circuit, A/D convertor circuit, single-chip microcomputer, relay and liquid crystal display, the signal of collection is passed sequentially through analog switching circuit by temperature sensor, A/D convertor circuit is exported to single-chip microcomputer, control signal is exported to relay and liquid crystal display, single-chip microcomputer and communicated by USB cable with trainee workstation using 101 or 104 Telecontrol Protocols by single-chip microcomputer.Information transmission and the overall process of processing when the present invention can completely show four distant experiments.Device is compact to be easy to use, and the distant experiment perceptual knowledge of lively four can be obtained by using present apparatus student.
Description
Technical field
The present invention relates to a kind of teaching testing device, more particularly to a kind of four distant experiment teaching device of hand held.
Background technology
In the skills training of dispatching automation maintenance person and person on duty, remote signalling, remote measurement, remote control, the four of remote regulating distant work
The teaching method of principle is mainly explained using PPT, and student feels abstract, and result of training is bad.Although some training centers have comprehensive
Automation equipment and main website training system are closed, but because four distant plates are encapsulated in cabinet, also can not intuitively be printed to student
As.
The content of the invention
The present invention is directed to above-mentioned problems of the prior art, there is provided a kind of four distant experiment teaching device of hand held,
Solves in the prior art the problem of four distant experimental modellings are abstracted, and result of training is bad.
The purpose of the present invention is mainly what is be achieved by following technical proposals：
Four distant experiment teaching device of hand held, including temperature sensor, analog switching circuit, A/D convertor circuit, single-chip microcomputer, relay
Device and liquid crystal display, the signal of collection is passed sequentially through analog switching circuit by temperature sensor, A/D convertor circuit is exported to list
Control signal is exported to relay and liquid crystal display, single-chip microcomputer and adopted by USB cable and trainee workstation by piece machine, single-chip microcomputer
Communicated with 101 or 104 Telecontrol Protocols.
Described relay is miniature remote controlled relay.
Advantages of the present invention effect is as follows：
The present apparatus is communicated by USB cable with trainee workstation using 101 or 104 Telecontrol Protocols, defeated using temperature as analog quantity
Enter, inputted using microswitch as intake, using relay as remote control and remote regulating object output, carried out using liquid crystal panel real
When presentation of information, when the present apparatus can completely show four distant experiments information transmission and processing overall process.Device is compact to be easy to
Use, the distant experiment perceptual knowledge of lively four can be obtained by using present apparatus student.
Brief description of the drawings
Fig. 1 is the structural schematic block diagram of the present invention.
