Background technology
Electronic building blocks refer to add electronic building brick on the basis of traditional building blocks, such as battery, motor, sound, light control
Electronic circuit and the elements such as system；Progressively rose in recent years and more and more, but either which kind of electronic building blocks, its 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 employ 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 is 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 position and the way to get there of line that multiple interfaces are put.
The content of the invention
In order to solve the problems of the prior art, the present invention provides a kind of electronic building blocks electric connection system and method.
The present invention provides a kind of electronic building blocks electric connection system, including main control module and at least two submodules, institute
The submodule having only is connected by power cord, ground wire, data cable, and the submodule only passes through power cord, ground wire, data cable
It is connected with the main control module.
As a further improvement on the present invention, the main control module is in series with battery by power cord, ground wire, data cable.
As a further improvement on the present invention, the data cable is the data communication line using half-duplex serial communication.
As a further improvement on the present invention, the main control module, be equipped with identical electrical apparatus interface on submodule, it is described
Electrical apparatus interface is any one in contact interface, electric shock interface, plug, plug.
Present invention also offers a kind of electronic building blocks electrical connection methods, using the half-duplex serial communication mode of single line,
All submodules are only together in series by power cord, ground wire, data cable.
As a further improvement on the present invention, all main control modules, the submodule connected by same data cable is not having
When sending data, input port is set to the input port with weak pull-up resistor or the input port of floating, if whole submodules
All select the input port of floating, then main control module is the input port with pull-up resistor, only when needing to send data, input
Eloquence is changed into delivery outlet and sends data, and input port is reverted to immediately if data sending is completed.
As a further improvement on the present invention, the Tx functions of universal asynchronous receiving-transmitting transmitter and Rx functions are merged into one
Rise, usually forbid Tx functions, open Rx functions, transmitting data are just to enable Tx functions, forbid Tx functions after being sent at once.
The beneficial effects of the invention are as follows：Simplify connection structure, it is only necessary to use power cord, ground wire, data cable this three
Line, reduces contact and is connected, and connection is more flexibly, conveniently.

Embodiment
The invention will be further described for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in Figures 2 to 7, a kind of electronic building blocks electric connection system, including 101 and at least two submodule of main control module
Block 102, all submodules 102 are only connected by power cord, ground wire, data cable, and the submodule 102 only passes through power supply
Line, ground wire, data cable 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 cable.
The present invention uses the half-duplex serial communication mode of single line, and all submodules 102 are all together in series, this
Sample, the interface of each module only have this three lines of power cord, ground wire and data cable, all interfaces are all made identical
, 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 line (G) and data cable (D), though it is unexpected it is reversed will not damage circuit, it is very safe（In addition there is mechanical structure can
To ensure that it will not be reversed）；Either primary module or submodule, all electronic modules all have one or more this interfaces
（It is probably multiple interfaces in mechanical structure, and is probably identical in electric appliance relation, certain primary module can also designs more than one
A 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 cable（Or contact）；
B) module having in system need to only use both threads（Or contact）, can vacate without using wire locations；If battery module
Only use anode and anode two lines, it is possible to without the line of D positions（Or contact）, and the module of other support types then may be used
The position that power cord is only vacated using ground wire and data cable is not had 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 cable（D）Function depending on specific module is different, and the definition of standard is data communication line, serial using half-duplex
Communication, communication speed require whole system to unify；Special module can be used using this line as other function control lines；
D) in the entire system, it can also be used in conjunction with traditional connection relation, multi-thread connection and inconvenience will be needed
Place changes the interface that is connected in series of the present invention into, and line is few and the module easy to be connected with primary module is still to use directly to connect
Connect.
A kind of electronic building blocks electrical connection methods, using the half-duplex serial communication mode of single line, all submodules
Only it is together in series by power cord, ground wire, data cable.
Data communication implementation method is described as follows：
A) single-wire data bus mode, as shown in Figure 3：Data cable i.e. in system in whole this three wire configurations is all to be connected to one
Rise, a that is, line, all modules on this line are set to band weak pull-up resistor in no transmission data（It is or floating
Sky, if whole submodules all select the input port of floating, main control module must be the input port with pull-up resistor）It is defeated
Entrance, is only just changed into Open-drain delivery outlets when module needs and sends data and sends data, once data sending is complete
Cheng Ze reverts to input port immediately；Certainly, adding competition mechanism 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（Send）
And Rx（Receive）It is merged together, usually forbids Tx functions to open Rx functions, transmitting data is just to enable Tx, after being sent i.e.
Quarter forbids Tx.
Above content is that a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
