Background technology
In grain depot monitoring system, single-chip microcomputer has extremely important effect to whole system as main control terminal.
And in order to save the energy, the wake-up for single-chip microcomputer is usually using the RTC alarm clock timings arousal function on single-chip microcomputer or use
Watchdog module is waken up, but both awakening modes need to open corresponding clock and configuration, is added to a certain extent
Big power consumption.In addition, once single-chip microcomputer crashes, then there is the state that can not be waken up.
Utility model content
To be solved in the utility model is existing single-chip microcomputer awakening mode, increased power dissipation, situation about can not wake up easily occurs
Etc. technical problem, so as to provide a kind of wireless awakening SCM system.
In order to solve the above technical problems, technical scheme is as follows used by the utility model:
A kind of wireless awakening SCM system, including host computer, wireless module, single-chip microcomputer and supplying cell, host computer with
Wireless module is bi-directionally connected, the CON4-1 pins of wireless module be connected between resistance R18 and electric capacity C3 after again by wire with
The 7th pin connection of single-chip microcomputer;Resistance R18 and electric capacity C3 are connected in series, and resistance R18 is connected with supplying cell, and electric capacity C3 connects
Ground;Supplying cell is powered to single-chip microcomputer.
The single-chip microcomputer uses 32 low-power scms of STMicw Electronics, model STM32F103R8T6.
Oscillating circuit is provided between the 5th pin of single-chip microcomputer and the 6th pin, the oscillating circuit includes oscillator
Y1, oscillator Y1 one end are divided into two-way, are connected all the way with ground capacity C4, and another way directly connects with the 6th pin of single-chip microcomputer
Connect;The oscillator Y1 other end is also classified into two-way, is connected all the way with ground capacity C5, and the 5th pin of another way and single-chip microcomputer connects
Connect.
The voltage of the supplying cell is 3.3V.
When system is in idle condition, single-chip microcomputer make whole system be in low-power consumption resting state, it is necessary to when, it is upper
Machine sends control command by wireless module, and wireless module is managed after receiving order by CON4-1 pins to the 7th of single-chip microcomputer
Pin, that is, reseting pin send a signal, and single-chip microcomputer is waken up, reduces the power consumption of system.Moreover, this practicality is new
Type host computer is waken up by wireless module, it is not necessary to is connected by wire, is reduced fault rate, avoided because space interference is made
The problem of into single chip microcomputer halt.
Brief description of the drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the circuit diagram that the utility model wireless module coordinates with single-chip microcomputer.

Six pins connect;The oscillator Y1 other end is also classified into two-way, is connected all the way with ground capacity C5, and the of another way and single-chip microcomputer
Five pins connect.Oscillator provides stable clock for system, and ground capacity can improve the stability of frequency of oscillation.
When not needing work, system is in idle condition, and single-chip microcomputer makes whole system be in the resting state of low-power consumption,
When in a dormant state, single-chip microcomputer can control the voltage regulator of external circuit to close, whole system 1.8V power supply area quilts
Power-off, oscillator are also de-energized, and the register and stand-by circuit only backed up maintains power supply, the work(of the reduction system of high degree
Consumption.When needing work, host computer sends control command by wireless module, and wireless module is managed after receiving order by CON4-1
Seventh pin of the pin to single-chip microcomputer, that is, reseting pin send a signal, and single-chip microcomputer is waken up, reduces system
Power consumption.Moreover, the utility model host computer is waken up by wireless module, it is not necessary to is connected by wire, is reduced fault rate, kept away
Exempt from due to the problem of space interference causes single chip microcomputer halt.
