Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, now compares accompanying drawing and describe in detail The embodiment of the present invention.
Fig. 1 is the structural representation of communication interface connectivity capabilities module of the present invention and modular platform.
Specifically, the communication interface of the present invention is used to connect and realize the communication between modular platform and functional module.It is excellent Selection of land, intelligent terminal include but is not limited to smart mobile phone, Intelligent bracelet, intelligent glasses etc.；Intelligent terminal is operated using Android System, IOS, Windows operating system, (SuSE) Linux OS etc..Functional module includes but is not limited to：Battery mould Block, air module, water module, bracelet module, bluetooth earphone module, locating module, apart from detection module, temperature detecting module, Memory module, NFC module, wireless charging module etc..
The communication interface includes：The first interface that is arranged in functional module and what is be arranged on modular platform second connect Mouthful, and first interface and second interface match.Modular platform may include multiple second interfaces, and modular platform passes through each second The first interface of interface linkage function module, realizes the extension of One function module.
Alternatively, first interface and second interface are 8 pin interfaces, including：First pin VIN, second pin DET0, 3rd pin DET1, the 4th pin VOUT, the 5th pin GND, the 6th pin DM, the 7th pin DP, the 8th pin GND.Below The function of each pin is defined：
First pin VIN is used for the plant-grid connection of functional module, for first kind functional module and the second class functional module Use, the division of first kind functional module and the second class functional module is realized by second pin DET0 and the 3rd pin DET1.
Second pin DET0 and the 3rd pin DET1 is used to classify to functional module, according to second pin DET0 and the Functional module is divided into four classes by three pin DET1 impedance height：
First kind functional module：Functional module is empty module or idle module, and the generic module need to only be plugged on modular platform On, no signal is into or out.
Second class functional module：Functional module is first kind power supply module, and the generic module needs modular platform to be provided for it Electrical characteristic, that is, electric energy is provided and communicated.Preferably, if modular platform is module frame, and the module frame is used for Intelligent terminal is connected, then the second class functional module, which is directly docked with module frame, uses.
3rd class functional module：Functional module is the second class power supply module, and the generic module needs modular platform to be provided for it Electrical characteristic, that is, electric energy is provided and communicated.Preferably, if modular platform is module frame, and the module frame is used for Intelligent terminal is connected, then the second class functional module, which is directly docked with intelligent terminal, uses.For example, the 3rd class functional module is to deposit Module is stored up, if then the memory module is given to intelligent terminal again after data are handled by module frame, data transfer can be caused Speed is slower, and the requirement to the processor of module frame is higher, causes cost increase, so, this generic module need directly and Intelligent terminal carries out data interaction, it is not necessary to intermediate transit, so as to improve message transmission rate.
4th class functional module：Functional module is battery or charging equipment, while can be charged the battery by VIN.
