Description

A kind of electronic building blocks electric connection system

Technical field

The utility model is related to electronic building blocks more particularly to a kind of electronic building blocks electric connection systems.

Background technology

Electronic building blocks refer to adding electronic building brick on the basis of traditional building blocks, such as battery, motor, sound, light control Electronic circuits and the elements such as system；Which kind of gradually rose in recent years and more and more, but either electronic building blocks, electricity Gas connection structure is entirely to be connected in parallel multiple sub-function modules using a main control module（Hereinafter referred to as submodule）Structure, As shown in Figure 1, each family is only to use different interfaces.In any case, although these electronic building blocks can be integrated now Go out powerful function, but the really very inconvenient thing of the line between its each submodule and primary module, powerful point System is even extremely complex, and the flexibility ratio for combining position is not strong enough, it is not easy to be generalized to age small user；Especially module is set With regard to bigger, the design and manufacture of various appliance contacts are all pretty troublesome things for meter and the difficulty of manufacture itself, it is also contemplated that The way to get there of position and line that multiple interfaces are put.

Invention content

In order to solve the problems in the prior art, the utility model provides a kind of electronic building blocks electric connection system.

The utility model provides a kind of electronic building blocks electric connection system, including main control module and at least two submodules Block, all submodules only by power cord, ground wire, data line connect, the submodule only by power cord, ground wire, Data line is connect with the main control module.

The main control module is in series with electricity by power cord, ground wire, data line as a further improvement of the utility model, Pond.

The data line is the data communication using half-duplex serial communication as a further improvement of the utility model, Line.

As a further improvement of the utility model, the main control module, be equipped with identical electrical apparatus interface on submodule, The electrical apparatus interface is any one in contact interface, electric shock interface, plug, plug.

The utility model has the beneficial effects that：Simplify connection structure, it is only necessary to using power cord, ground wire, data line this Three lines, reduce contact and connect, and connection is more flexibly, conveniently.

Specific implementation mode

The utility model is described in further detail for explanation and specific implementation mode below in conjunction with the accompanying drawings.

As shown in Figures 2 to 7, a kind of electronic building blocks electric connection system, including main control module 101 and at least two submodules Block 102, all submodules 102 are only connected by power cord, ground wire, data line, and the submodule 102 only passes through power supply Line, ground wire, data line are connected with the main control module 101.

As shown in Figures 2 to 7, the main control module 101 is in series with battery 103 by power cord, ground wire, data line.

The utility model uses the half-duplex serial communication mode of single line, and all submodules 102 are all together in series, In this way, the interface of each module only has this three lines of power cord, ground wire and data line, and all interfaces are all made complete phase With, lead（Or contact）Few, production and processing is easy；Entirely the same is easy to produce；As all according to power cord (B), This sequence of ground wire (G) and data line (D) will not damage circuit unexpected reversed, very safe（In addition there is mechanical structure It can ensure that it will not be reversed）；Either primary module or submodule, all electronic modules all have one or more is this to connect Mouthful（It may be multiple interfaces in mechanical structure, and may be identical in electric appliance relationship, certain primary module can also design incessantly One this electrical apparatus interface is to improve communication speed）.

The mechanical structure of electrical apparatus interface is described as follows：

A) interface all only has this three lines of power cord, ground wire and data line（Or contact）；

B) module having in system need to only use both threads（Or contact）, the wire locations not used can be vacated；Such as battery mould Block just only uses anode and cathode two lines, so that it may with without the line of the positions D（Or contact）, and the module of other support types The position that ground wire and data line then can be only used and vacate power cord does not have to.

C) contact/electric shock structure or plug/socket structure can be used in interface.

D) contact（Or plug-in unit）Position be placed on be not center position with prevent it is anti-inserted after can also be powered.

Electric connecting relation is described as follows：

A) each module has oneself independent power-supply management system；

B) power cord on three lines（B）And ground wire（G）It is that whole system is unified；

C) data line（D）Function depending on specific module is different, and the definition of standard is data communication line, using half-duplex Serial communication, communication speed require whole system to unify；Special module can make using this line as other function control lines With；

D) in the entire system, it can also be used in conjunction with traditional connection relation, i.e., will need multi-thread connection and not side Just place changes the interface that is connected in series with of the utility model into, and the module few and convenient for being connect with primary module of line is still to use It is directly connected to.

A kind of electronic building blocks electric connection system, using the half-duplex serial communication mode of single line, all submodules Only it is together in series by power cord, ground wire, data line.

A kind of data communication of electronic building blocks electric connection system is described as follows：

A) single-wire data bus mode, as shown in Figure 3：Data line i.e. in system in whole this three wire configurations is all to connect To together, that is, line, all modules on this line are set to band weak pull-up resistor in no transmission data（Or Floating, if it must be the input port with pull-up resistor that whole submodules, which all select the input port of floating, main control module,）'s Input port is only just changed into Open-drain delivery outlet transmission datas when module needs transmission data, once data are sent Completion then recovers immediately as input port；Certainly competition mechanism, is added in communications protocol will be relatively reliable.

B) two-wire merging data bus mode, as shown in Figure 4：By Uart（Universal asynchronous receiving-transmitting transmitter）Tx（It sends） And Rx（It receives）It is merged together, Tx functions is usually forbidden to open Rx functions, transmitting data are just to enable Tx, after being sent i.e. Quarter forbids Tx.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard To belong to the scope of protection of the utility model.
