The population structure of temperature survey and heating control system is shown in Fig. 5-1.System comprises that mainly scene temperature collection, real time temperature show, add the setting of thermal control parameter, heater circuit control output, optical filter wheel motor-driven etc.
Temperature collection circuit reaches single-chip microcomputer with numeral output with scene temperature, and single-chip microcomputer is in conjunction with the target temperature of scene temperature and user's setting, and solidified increment type PID control algolithm calculates real-time controlled quentity controlled variable according to programming.Enable photoelectric isolating driving circuit with this controlled quentity controlled variable, the duty of decision heater circuit makes temperature progressively be stable at user's target value set.Various state parameters in system's running show in real time by LCD.System's control block diagram such as Fig. 5-1; The system drive part is as Fig. 5-2.
Systematic control algorithm
System adopts pulsewidth modulation (PWM) control method based on increment type PID algorithm, and promptly the dutycycle of PWM square wave is tried to achieve by increment type PID algorithm.The output of increment type PID algorithm is
ΔU
n＝Kp[(e
n-e
n-1)+(T/T

The Microchip single-chip microcomputer
Native system adopts PIC16F877 as central processing unit, and the PIC Series of MCU of Microchip technology company adopts Reduced Instruction Set Computer, Harvard's (Harvard) dual bus and two-stage instruction flow line line structure, ratio of performance to price height.Have high-speed, low-work voltage, low-power consumption, the bigger direct driving LED ability of input and output (irritate electric current and can reach 25mA), one-off programming, the low price of chip, small size, instruction are easy to learn easy-to-use.
Scene temperature is gathered
As Fig. 6 and Fig. 7, scene temperature is obtained by temperature sensor.In native system, the MLX90614 temperature measurement module that temperature sensor selects for use Melexis company to produce, it is to use infrared temperature measurement apparatus very easily, its all module has all been carried out verification before dispatching from the factory, and can directly export linearity or almost signal, have good interchangeability, removed complicated trimming process from.
The LCD display circuit
In the heating process, the parameters such as target temperature that the actual temperature of controlled device, user set show in real time by the LCD display circuit.The LCD display circuit adopts the LM032L chip of Hitachi company, and it was illustrated in fig. 7 shown below with being connected of PIC16F877.
The heat driven circuit
Heater X1 selects AC220V for use, the heat lamp of 100W, and its wavelength covers between whole ultrared.Because the I/O mouth output loading capability of PIC16F877 is 40mA to the maximum, can't directly drive heating element heater, must realize the control of single-chip microcomputer by middle drive circuit to the power apparatus duty.In the practical application, adopt relay or A.C. contactor to drive indirectly usually.Because relay or A.C. contactor have the Mechanical Contact characteristics, thereby have reduced the stability and the reliability of control system integral body to a great extent.For fear of the shortcoming of mechanical contact switch, native system is selected for use based on the isolated middle drive circuit of the complete photoelectricity of controllable silicon.Controllable silicon is a high power switch type semiconductor device, can work under high voltage, big current condition, has and does not have the machinery contact, volume is little, be convenient to advantage such as installation, is widely used in the power electronic equipment.The heat driven circuit diagram as shown in Figure 6.
PIC16F887 calculates real-time controlled quentity controlled variable according to scene temperature with target temperature and relevant control parameter that the user sets.This controlled quentity controlled variable is write in the depositor of single-chip microcomputer intervalometer 1, with the dutycycle of decision output PWM ripple.Between the high period of PWM ripple, the bi-directional light electric coupler by current-limiting protection resistor R 4 works on power, and the grid of bidirectional triode thyristor D1 is by the signal triggering conducting via R1, R2 and bi-directional light electric coupler, and heater circuit gets electric work; Between PWM ripple low period, the bi-directional light electric coupler ends, and bidirectional triode thyristor D1 grid Triggerless is turned off, and the heater circuit outage quits work.
R3 in the circuit, C2 form the capacitance-resistance absorptive unit, and the self induction electromotive force that inductive element produced in the heater circuit in the time of can reducing the controllable silicon shutoff is impacted the silicon controlled overvoltage.R1, C1 form low-pass filter unit, can reduce the influence of bi-directional light electric coupler false triggering to subsequent conditioning circuit.Simultaneously, strong and weak circuit has thoroughly been isolated in the use of bi-directional light electric coupler, has avoided the interference of high power device to single-chip microcomputer.
Software design
As Fig. 8, Fig. 9 and Figure 10, system program by mastery routine, temperature acquisition subprogram, add thermal control subprogram, keyboard scan subprogram and interruption subroutine etc. and partly form.Mastery routine is mainly finished the initialization and the self check of each parts of heating control system, and the coordination of each functional module in the actual measurement.Subprogram such as keyboard scan and control algolithm utilizes the abundant interrupt resources of PIC, and externally interruption and intervalometer overflow and finish above-mentioned work in the interruption subroutine.
