Embodiment
These two electric capacity of single-chip minimum system circuit C9 and C10 are the load capacitance of crystal oscillator, are connected on respectively electric capacity on two pin of crystal oscillator and over the ground, and generally at tens pico farads, it can have influence on resonant frequency and the output amplitude of crystal oscillator.Two capacity earths, in fact be exactly the dividing potential drop electric capacity of capacitance three-point type circuit, earth point is exactly dividing point, be that dividing point is as reference point taking earth point, the input and output of vibration pin are anti-phase, but be that quartz crystal two is brought in from shunt-resonant circuit, form a positive feedback to ensure circuit persistent oscillation.
The reset signal of 89 series monolithics is to be input to the Schmidt trigger in chip from RSET pin.When system is during in normal operating conditions, and oscillator stable after, if more than having a high level on RSET pin and maintaining 2 machine cycles (24 cycles of oscillation), CPU just can respond and by system reset.The reset mode of SCM system has: hand push button resets and electrification reset.
(1) manually button S1 resets exactly in the time that button is pressed, and directly gives high level of monolithic processor resetting pin.Because actuation time of people is much larger than the required shortest time of monolithic processor resetting, thus manually button to reset be feasible.
(2) electrify restoration circuit of C8 and R5 single-chip microcomputer in series.The course of work of electrification reset is in the time powering up, reset circuit adds to an of short duration high level signal of RSET end by electric capacity, this high level signal falls after rise gradually along with the charging process of VCC to electric capacity, and the high level lasting time of RSET end depends on the charging interval of electric capacity.For guarantee system can reset reliably, the high level signal of RSET end must maintain the sufficiently long time.
Temperature sensor of the present invention adopts DS18B20, and DS18B20 has 64 unique long lasered ROM codings.8 that start is product type label, and 48 that follow is unique sequence number of this DS18B20 self, and last 8 is 56 CRC CRCs above.The effect of lasered ROM is to make each DS18B20 different, can realize the object that articulates multiple DS18B20 in a bus by the control of program.
Air exhausting device we drive the adhesive of relay with positive-negative-positive triode and disconnect control fan rotation whether.Reverse parallel connection diode in relay two ends is in order to protect triode; because relay coil can induce very high voltage in the moment disconnecting; this voltage can puncture triode; diode of reverse parallel connection can effectively discharge the voltage of induction, thereby has effectively protected triode not breakdown.
Heater we drive energising that relay carrys out control heater whether with positive-negative-positive triode too.Because the water temperature that needs tank the inside will rise timely, so handy powerful heater, meanwhile, relay is the relay of handy large electric current also.Consider that relay need to flow through very large electric current, if relay is drawn in PCB, conductor width must be more than 10cm, and thickness, more than 1mm, is unpractical like this.So we must be welded on relay in an other circuit board.
