Accompanying drawing explanation
Can understanding feature and advantage of the present utility model clearly by reference to accompanying drawing, accompanying drawing is schematic and should not be construed as and carry out any restriction to the utility model, in the accompanying drawings:
Fig. 1 shows the structural representation of device of a kind of automatic detection thermal resistance in the utility model embodiment, thermopair conduit.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
In order to better understand with apply the utility model proposes automatic detection thermal resistance, thermopair conduit device, carry out the detailed description of following diagram and corresponding content, and the utility model does not limit to the detailed description of following diagram and corresponding content.
As shown in Figure 1, the utility model provides the device of a kind of automatic detection thermal resistance, thermopair conduit, comprising: filtration module, AD conversion module, single-chip microcomputer and switch.
Particularly, filtration module chooses the low cut-off filter being less than 10Hz, for extremely low cutoff frequency low-pass filter, use differential mode capacitor device large as far as possible, and resistor little as far as possible, to realize alap frequency cutoff and in-band noise, 500 Ω resistance in seriess generate wave filter, CDIFF needs to be 15 μ F, and needs are 1.5 μ F by CCM; AD conversion module chooses instrument amplifier, and wherein, element is integrated in inside by instrument amplifier, and controls at ± 1 DEG C the measuring accuracy of thermopair feeble signal.The structure of its uniqueness makes that it has high cmrr, high input impedance, low noise, low linear error, low offset drift gain arrange the features such as flexible and easy to use, makes it gain great popularity in data acquisition, sensor signal amplification, high speed signal adjustment, Medical Instruments etc.
Single-chip microcomputer is used for the magnitude of voltage of AD conversion module conversion to be converted into corresponding temperature value, by judging whether temperature value data carry out gauge tap in preset range, wherein, and on-off circuit gauge tap.When on-off circuit normally works, namely when there is conduit and inserting, on-off circuit is fixed on the first state or the second state, and when there is not conduit and inserting, on-off circuit switches between the first state and the second state.
Further, the value of microprocessor detect AD conversion module thermopair and thermal resistance is not within preset threshold range, when there being thermopair conduit to insert, if single-chip microcomputer just in time gathers the value of thermal resistance input AD conversion module, judge the value after abnormal rear switching over state acquisition thermopair input AD conversion, this value converts to after temperature value within preset threshold range, and on-off circuit stops switching and starts the value gathering thermopair; Same when there being thermal resistance conduit to insert, if single-chip microcomputer just in time gathers the value of thermopair input AD conversion module, judge the value after abnormal rear switching over state acquisition thermal resistance input AD conversion, this value converts to after temperature value within preset threshold range, and on-off circuit stops switching and starts the value gathering thermal resistance.
A kind of automatic detection thermal resistance that the utility model proposes, the device of thermopair conduit also comprise: radio-frequency signal generator be used for will the heat direct heater that send to preset temperature, and in heating process, adopt pid algorithm, power increases gradually, when collecting temperature exceedes preset temperature, power starts to reduce, and finishing temperature is stabilized near preset temperature; And alarm module is used for when collecting temperature exceedes preset temperature, reports to the police.Particularly, if real time temperature rises to maximum temperature, such as: more than 90 DEG C, or be less than minimum temperature, such as: 30 DEG C, device carries temperature protection function, namely interrupt energy transferring and report to the police.Wherein, type of alarm is for sounding or flashing indicator light.
The device of a kind of automatic detection thermal resistance disclosed in the utility model, thermopair conduit, comprises filtration module, AD conversion module, single-chip microcomputer and switch; The filtering circuit in the filtration module before the A/D convertor circuit in AD conversion module is controlled by the on-off circuit in switch, single-chip microcomputer gathers the value after A/D convertor circuit, value according to gathering converts corresponding temperature value to, judges whether temperature value data carry out gauge tap in preset range.The utility model can adapt to two kinds of conduits and use simultaneously, and efficiently, accurately detected catheter is thermal resistance or thermopair automatically.
