Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Like Fig. 1, shown in 2, a kind of multi-functional quenching medium cooling characteristics tester of the utility model comprises the thermopair 2 that is installed on the handle 1, and with the main frame 3 of thermopair 2 wireless connections.Thermopair 2 can adopt K type thermopair.
Be provided with thermopair sampled signal amplifying unit 11, AD modular converter 12 and digital modulation unit 13 in the described handle 1; One end of described thermopair sampled signal amplifying unit 11 is electrically connected with thermopair 2, and the other end is connected with digital modulation unit 13 through AD modular converter 12.Wherein, AD modular converter 12 can adopt data converter AD595AQ, cooperates amplifying circuit that the output signal of K type thermocouple is amplified.Also be provided with the DC12V power supply in the handle 1, be AD595AQ analog to digital converter, amplifying circuit power supply, when guaranteeing that thermopair 2 works between 0 ℃～1200 ℃, the output signal of thermopair 2 is amplified and cold junction compensation.
Described main frame 3 comprises the numeral conciliation unit 31 that can receive digital modulation unit 13 wireless signals; Numeral is reconciled unit 31 and is connected with Route Selection control module 32, DA modular converter 33, signal processing unit 34 and MicrosoftWindows CE operating system development board unit 35 successively; Signal processing unit 34 also is connected with keyboard 36, and Microsoft Windows CE operating system development board unit 35 also is connected with touch-screen 37.Described Microsoft Windows CE operating system development board unit 35 can be selected S3C2440 Microsoft Windows CE operating system development board unit for use.Power supply is each module for power supply in the above-mentioned main frame 3.Described Route Selection control module 32 has comprised router and signal selection control module, selects control module can select any one tunnel of router to control through signal.
In order to reach the purpose that can test multiple spot simultaneously, as shown in Figure 3, a plurality of handles 1 can be set, include identical circuit in each handle 1, promptly comprise the thermopair sampled signal amplifying unit 11, AD modular converter 12 and the digital modulation unit 13 that connect successively; The input end of each thermopair sampled signal amplifying unit 11 is connected with a thermopair 2; The quantity that is handle 1, thermopair 2 is identical.Be provided with in the described main frame 3 several and digital modulation unit 13 one to one numeral reconcile unit 31, all numerals are reconciled unit 31 and all are electrically connected with Route Selection control module 32.The utility model can pass through a main frame, tests a plurality of thermopairs 2 simultaneously, thereby tests out the hardening media cooling characteristics of a plurality of points simultaneously, makes things convenient for client's demand.
The Microsoft Windows CE operating system development board unit of stating 35 is provided with the RJ45 interface that links to each other with external computer.
The signal processing unit 34 of the utility model adopts single chip computer AT MEGA16_TQFP44; The low-power consumption 8 that it is based on the AVRRISC structure of enhancing is the CMOS microcontroller; Because its advanced instruction set and single clock cycle instruction time; The data throughput of ATMEGA16_TQFP44 is up to 1MIPS/MHZ, thereby can delay the contradiction of system between power consumption and processing speed.The ATMEGA16_TQFP44 kernel has abundant instruction set and 32 general purpose working registers; All registers are all directly patrolled unit (ALU) with calculation and are connected; Make an instruction can in a clock period, visit two independently registers simultaneously; This structure has improved code efficiency greatly, and has and be up to 10 times numerical control throughput than common CISC microcontroller.SP F1ash allows program storage through the ISP serial line interface in the sheet, and perhaps universal programmer is programmed, and also can edit through the boot that runs among the AVR kernel.Through the Flash that becomes in 8 RISC CPU and the system is integrated in the chip, ATMEGA16_TQF44 uses for many embedded Control low cost solution flexibly is provided.At first; Utilize 8 tunnel 10 ADC that input voltage signal is sampled with optional differential input stage programmable-gain; Analog signal conversion is become binary code because voltage signal has been represented the temperature value of thermocouple, so this binary code also just corresponding some temperature values.Because inevitably there is interference in test environment, after adopting filtering circuit, still exists and disturb, so when AD sampled, the method that adopts repeatedly sampling to average reduced to disturb the influence to the result.
The signal that thermopair 2 collects is transferred to thermopair sampled signal 11 and carries out the signal amplification; And then process AD modular converter 12 carries out analog to digital conversion; Signal after the conversion arrives main frame 3 through 13 backs, digital modulation unit through wireless transmission, is received by the digital demodulation unit in the main frame 3 31; Select to deliver to DA modular converter 33 after the control through Route Selection control module 32 then, signal is delivered to signal processing unit after handling through DA modular converter 33.Because inevitably there is interference in test environment, after adopting filtering circuit, still exist and disturb, adopt wireless transmission, can be good at suppressing to disturb, can arrive good repeatability and repeatability.
