Alert device.
Infrared thermometry is the physical essence i.e. heat radiation using infra-red radiation.Heat sensor is to utilize thermal effect of radiation,
Cause temperature to raise after making sensitive detection parts reception radiation energy, and then senser element is affected by temperature physical property and change.
The change of the wherein a certain performance of detection, it is just detectable to go out to radiate.It is that radiation is detected by Seebeck effect in most cases,
It is changed into measuring after electricity by suitably changing, infrared thermometry scope is at -32 DEG C -- 400 DEG C.The electric signal of this change
Referred to as analog signal, will realize that single-chip microcomputer control must be converted into this analog signal in the circuit of data signal, referred to as mould
Number converter, A/D conversions typically will be through over sampling, holding, 4 processes of quantization and coding, and in actual circuit, these processes have
Be merge carry out, simultaneously realize.I.e. outside various analog signals must be transformed to data signal by A/D converter
Afterwards, microprocessor chip could be sent into.
The model DS18B20, DS18B20 of contact type temperature sensor are the single wire bus devices of DALLAS companies production,
Only need to take when microprocessor is interfaced that on 1 I/O port, and a bus tens DS18B20 can be mounted, with line
Road is simple, the characteristics of small volume, and the temperature measurement system circuit constituted with it is very simple.Temperature measurement range -55 DEG C~
Between+125 DEG C, there be temperature upper and lower limit alarm setting inside.Each DS18B20 chips have unique sequence number, so can
To be connected to using multiple DS18B20 in same bus simultaneously, multi-point temperature measurement system is constituted.DS18B20 internal structures are main
It is made up of four parts：64 lasered ROMs, temperature sensor, non-volatile temperature alarming trigger TH and TL, configuration registers.
Device is digital component, and fault rate is very low, strong interference immunity.DS18B20 has two kinds of power supply modes：One kind supplies for data wire
Electrically, now VDD is grounded, and it is to obtain energy from data wire at one's leisure by internal capacitance, to complete temperature survey, separately
One kind is externally fed mode (VDD meets+5V), and the corresponding time for completing temperature survey is shorter.Monobus based on device is set
Meter, the data detected can be sent directly into single-chip microcomputer and be handled.
The model STC89C52 of single-chip microcomputer, is integrated with each composition portion of a microcomputer on a fritter chip
Point.Each single-chip microcomputer includes：The microprocessor CPU of one 8；Data storage RAM in one 512K piece；In 4K pieces
Program storage；The I/O interfaces P0-P3 of four 8 parallel-by-bits, each interface can both be inputted, can also exported；Two timings
Device/register；The Interrupt Control System of five interrupt source；Serial i/O mouthfuls of one full duplex UART；Piece internal oscillator and clock
Generation circuit, but quartz crystal and trimmer needs are external.Highest allows frequency of oscillation to be 12MHZ.Above various pieces are led to
Internal bus is crossed to be connected.There are 2 to be exclusively used in main power source pin in 40 pins, the pin of 2 external crystal oscillators, 4 controls or with
The pin of other power supply multiplexings, and 32 input and output I/O pins.DS1302 is that one kind that DALLAS companies of the U.S. release is high
Performance, low-power consumption, the real time clock circuit with RAM, it can to year, month, day, Sunday, when, minute, second carry out timing, with intercalation
Year compensation function, operating voltage is 2.5V~5.5V.Synchronized and communicated with CPU using three-wire interface.Memory is used for coordinating
The data sent by temperature detection circuit of single-chip microcomputer processing, 24C02 is erasable type PROM, using 256*8-bit institutional framework and
Two-wire serial interface.Voltage can allow as little as 1.8V, and operating current is only 1mA.24C02C, which has, also writes function, and every page is respectively
8 bytes.
Display screen uses LCD1602 ocra font ocr displays, using HD44780 as base controller, built-in DDRAM,
CGROM and CGRAM, DDRAM are exactly display data RAM, for depositing character code to be shown.In order to intuitively show monitoring
Value, one piece of LED nixie display of instrument configuration is for showing real time temperature and silicon carbide, more straight compared with than liquid crystal display
See eye-catching.
Data interface module is data transmission interface, and the data-interface of instrument is carried out data transmission using RS232, is most normal
A kind of serial communication interface.Uneven transmission means is taken, i.e., so-called single-ended communication can be completed with simple transmission line
Data transfer, protocol conversion chip is to use MAX232A, and connection computer can be controlled and gathered data.
Simulate control module to load using Control, complete the control function of temperature.Instrument is provided with abundant
I/O interfaces, the expanded function for developing single-chip microcomputer makes monitor have practical ease for use and compatibility.
In use, food to be placed on to the switch that fan 4 is opened in lunch box 7 or on curtain 6, gear number is regulated, starts to blow
Food, while opening the switch of automatic temperature measurement instrument 5, starts to measure the temperature of food, surveys measured temperature and show on a display screen；
If reaching the edible temperature of human body, it is possible to feeding, if being also above the edible temperature of human body, continue to be blown with fan 4,
Then measured again with automatic temperature measurement instrument 5.
Embodiment 2
As shown in figure 4, food cooler, lunch box 7 is open hollow cylindrical structure, other structures be the same as Example 1.
