Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, temperature sensor DS18B20, keyboard and LCDs, storer 24C02, pilot relay are connected with microcontroller AT89S52 respectively, and pilot relay is connected respectively with well heater with oil pump.Single chip computer AT 89S52 is by reading the temperature value of temperature detecting unit, and by after comparing with setting value, make control corresponding and export the pilot relay that drives well heater, thereby the power of change well heater remains within the range of set temperature temperature value to reach.As shown in Figure 5, be in series with the electric energy metrical unit in described control device, electric energy metrical unit one end is connected with the indoor power supply socket, and the other end is connected with the power supply input of control device, and the electric energy metrical unit is an electric energy meter.
The utility model selects the AT89S52 of atmel corp as microcontroller.AT89S52 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontrollers, has 8K at system programmable Flash storer.
AT89S52 has following standard feature: 8k bytes Flash, 256 byte RAM, 32 I/O mouth lines, WatchDog Timer, 2 data pointers, three 16 bit timing device/counters, 2 grades of interrupt structures of one 6 vector, crystal oscillator and clock circuit in the full duplex serial port, sheet.
This ground heating control system mainly detects in real time to flowline temperature, scavenge pipe temperature and indoor temperature, and comes the power of control heater by the temperature of each point, thereby the temperature of regulating each point is within the area requirement of setting.
Temperature sensor DS18B20 is the one-line digital temperature sensor that DALLAS company produces, its temperature measurement range is-55～+ 125 ℃, 9～12 the A/D conversion accuracy that is set to able to programme, thermometric resolution can reach ± and 0.0625 ℃, dut temperature is exported with serial mode with 16 bit digital quantity of sign extended.This temperature sensor interface is simple, accuracy of detection is high, satisfy the input that this control requires, and circuit is simple, has reduced production cost.The elementary diagram of DS18B20 as shown in Figure 2.
Keyboard mainly contains the ON/OFF switch, key is set, intensification key and four keys of cooling key are formed, mainly finish temperature control system startup, stop the setting with parameter.
ON/OFF switch: finish the startup and shutdown function.
Key is set: the parameter that selection will be provided with, as: the bound of flowline and scavenge pipe temperature and the setting of indoor temperature.
Intensification key and cooling key: the height when the control temperature is set.
LCDs mainly is the demonstration of finishing temperature detection value, can demonstrate oil pipe, scavenge pipe and indoor temperature value and setting value thereof, can observe each temperature value intuitively by this display screen, is convenient to each temperature value of real-time display setting.
That storer is chosen is the EEPROM 24C02 with iic bus, advantage such as it has power-down protection, communication interface is more and agreement is simple.This device carries out read-write operation by the iic bus interface.It mainly is to be used for storing each desired temperature and password setting.The wiring diagram of itself and single chip computer AT 89S52 is as shown in Figure 3:
