Concrete operating principle and process are as follows:
After machine powers on, mainboard locates standby mode at this time:
1, the signal (pressing on & off switch on hand controller) of booting is requested on hand controller when host MCU(U1) is received, on mainboard
MCU(U1) start automatic operation mode by scheduled program, if not having to receive hand controller again in this mode process
Other request signals, automatic operation mode work always, just can automatic shutdown until the work timing time is until.If
There are other keys to be pressed during this, the MCU(U1 on mainboard) understand signal according to different requests, mainboard is controlled respectively
Corresponding driving (such as: heating, air pump load) is made in other loads of system, to reach the complete job requirement of product.
2, the working method of driving load: the load driving of this control circuit is substantially the driving switched using metal-oxide-semiconductor
Mode tells about its working method by taking the air valve control circuit 1 in Figure 10 as an example: as the MCU(U1 on mainboard) receive unlatching gas
When the instruction of valve controling circuit 1, MCU(U1 on mainboard) 14PIN can export high level (+5V), give metal-oxide-semiconductor Q1 through R1
Control electrode, after metal-oxide-semiconductor is high level, the pole D and the pole S of metal-oxide-semiconductor are connected immediately, at this moment, it is logical to be inserted in solenoid valve on J1 terminal
Electricity adopts open electromagnetic valve.This is the course of work that the driving of MSO pipe is opened;
As the MCU(U1 on mainboard) internal command 14PIN is when closing high level, at this moment by R1 by the electricity of metal-oxide-semiconductor control electrode
Pressure drags down, and the control pole tension of metal-oxide-semiconductor is 0V at this time, so the pole D of metal-oxide-semiconductor and the pole S disconnect, then being inserted in the solenoid valve on J1
Power-off is the course of work that metal-oxide-semiconductor driving is closed so closing.Other loads are identical with this, and are no longer repeated.
3, the course of work of motor positive and inverse: such as the motor positive/reverse rotation circuit in Figure 10, as the MCU(U1 on mainboard) it receives
It is required that motor rotate forward request signal when, the MCU(U1 on mainboard) 6PIN(is shown in motherboard circuit schematic diagram) high level can be exported
(+5V), voltage give the base stage of Q7 power tube, the collector and emitter conducting of Q7, the relay after current-limiting resistance R13 through R21
Device K1 is attracted conducting, and power supply is flowed into from the anode for being inserted in J7 terminal motor, flowed out from electrode negative, realizes the work that motor rotates forward
Process.
As the MCU(U1 on mainboard) when receiving the request signal for requiring motor reversal, MCU(U1 on mainboard) 15PIN
(see motherboard circuit schematic diagram) can export high level (+5V), and voltage gives the base stage of Q8 power tube through R22, the collector of Q8 and
Emitter conducting, relay K2 is attracted conducting after current-limiting resistance R14, and power supply is flowed into from the cathode for being inserted in J7 terminal motor, from
The outflow of motor anode, realizes the course of work of motor reversal.
