Specific embodiment
With reference to the accompanying drawings and examples, the following further describes the technical solution of the present invention.
As shown in figure 3, a kind of plug and play can include three parts: hand by the peripheral module of single-chip microcontroller automatic identification altogether
Machine client, SCM system overall control center and each discrete block (such as steering engine, relay, stepper motor).As shown in Figure 1,
Single-chip microcontroller as overall control center be connected with bluetooth module for and cell phone client communicated and NRF24L01 channel radio
Believe that module is used to broadcast number information to single-chip microcontroller；As shown in Fig. 2, being connected on the single-chip microcontroller being connected directly with discrete component
NRF24L01 wireless communication module is for receiving the number information that overall control center is sent.Further, each discrete component module
It is equipped with independent register.Wherein, all single-chip microcontrollers are respectively connected with power supply unit.
Wherein, all interfaces and connecting line do standardization processing；It is specific as follows: the monolithic being connected directly with discrete component
