Description

Non-programmed automatic tracking electronic building blocks cart system

Technical field

The present invention relates to a kind of non-programmed automatic tracking electronic building blocks cart system, belong to electronic technology field.

Background technology

There is a lot of tracking cart in the market, major part is all use single-chip microcomputer or other chips as control center, not only needs complicated programming process, but also needs a large amount of welding and debugging, be not suitable for very much the study of students in middle and primary schools.And the existing building blocks commercially occurred are mostly mechanical, seldom have electronic type, with game with the use of more rare, be all much adopt high quality plastic to make building blocks, by the shape that bindiny mechanism's connection composition is different between building blocks.

Summary of the invention

For the problems referred to above, the present invention aims to provide a kind of electronic modular system with certain function, not only with low cost, simple to operate, reliability is high, good stability, and can with substantially increasing the understanding of students in middle and primary schools to electromechanical integration knowledge and the interest of study.

For realizing this object, the technical solution used in the present invention is to provide a kind of non-programmed automatic tracking dolly electronic modular system, it is characterized in that, this electronic modular system is made up of photosensitive sensor module (1), photosensitive sensor module (2), voltage comparator module (3), power module (4), motor drive module (5), reducing motor (6) and reducing motor (7), and all modules are all made up of the module with difference in functionality on pcb board welding electronic elements; Photosensitive sensor module perception black and white band, compares process by data line transfer by information in voltage comparator module (3), then the result obtained is sent to motor driver module (5), and drives corresponding electric machine rotation.

Electronic building blocks cart system all adopts PH2.0-4P interface to connect, the employing of transmitting terminal interface+, T, R, the arrangement of-(positive pole, emitter, receiving pole, negative pole) order, the employing of receiving end interface+, R, T ,-order arranges, and so not only connects simple, and not easily wrong plug.

Another innovative point of the present invention is that the design of power module (4) can realize being connected between any two modules, both can make communication conductor, again for all modules provide electric energy.

The invention has the beneficial effects as follows: using modules in non-programmed automatic tracking electronic building blocks cart system as one block of building blocks, every block building blocks are fixed on one containing on the suitable carrier of wheel unit, distance between guarantee two light sensors is in 2 cm situations, be linked in sequence by data line and just can realize automatic tracking function, without the need to programming, simple to operation, be applicable to very much not having the students in middle and primary schools of Fundamentals of Electronic Technology to complete tracking cart to make, understand its workflow and principle.

Embodiment

The present invention is further described by reference to the accompanying drawings: as shown in Figure 1, a kind of non-programmed automatic tracking electronic building blocks cart system, is made up of photosensitive sensor module (1), photosensitive sensor module (2), voltage comparator module (3), power module (4), motor drive module (5), reducing motor (6) and reducing motor (7).

As shown in Figure 2, photosensitive sensor module (1) and (2) mainly utilize the extinction principle of black, change the intensity of illumination that photoresistance GR2 receives, and then change module output voltage values; Resistance R3 is slide rheostat, is mainly used in two photosensitive sensor module initial differential pressure to set to zero.Have certain barrier between light emitting diode D1 and photoresistance GR2, illumination, by reflection, is applied on photoresistance GR2.

As shown in Figure 3, the pressure value of photosensitive sensor module (1) and (2) is input in voltage comparator module (3), exports corresponding signal after treatment.

As shown in Figure 4, motor drive module (5) utilizes the on-off principle of triode to design, and controls corresponding LED lighting and voltage output by the signal received.

As shown in Figure 5, in power module (4), have four lines, both sides be power lead, middle two is signal wire, can realize like this being connected to arbitrarily between above-mentioned two modules, both can make communication conductor, again for all modules provide electric energy.

When power module (4) is connected between voltage comparator module (3) and motor driver module (5), by photosensitive sensor module (1) and (2) collection signal, by carrying out analyzing and processing in wire transmission to voltage comparator module (3), then the result obtained is sent in motor driver module (5), finally drive corresponding reducing motor to rotate, tracking cart just can travel along black-tape; In like manner, also power module (4) can be placed on two photosensitive sensor modules (1) and between (2) and voltage comparator module (3), signal circulation style is the same.

Illustrate in conjunction with principle of the present invention and effect: when photosensitive sensor module (1) is fallen in black bands, the intensity of illumination that photoresistance in photosensitive sensor module (1) is received reduces, and then photosensitive sensor module (1) output voltage values is raised, the voltage of photosensitive sensor module (1) and photosensitive sensor module (2) is compared by voltage comparator, cause reducing motor (7) to rotate, dolly is turned right; Then photosensitive sensor module (2) is fallen in black bands, the intensity of illumination that photoresistance in photosensitive sensor module (2) is received reduces, and then photosensitive sensor module (2) output voltage values is raised, the voltage of photosensitive sensor module (2) with photosensitive sensor module (1) is compared by voltage comparator, cause reducing motor (6) to rotate, dolly is turned left.
