Embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to explain the present invention, but are not used for limiting scope of the present invention.
As shown in Figure 1, the indoor temperature control terminal of present embodiment comprises: power module, main control module, temperature collect module, analog-to-digital conversion module, transport module.Power module, temperature collect module, analog-to-digital conversion module and transport module all are connected main control module.
Temperature collect module is gathered indoor temperature in real time, and the temperature of gathering is sent to main control module.
The temperature collect module of present embodiment is as shown in Figure 2, comprising: temperature signal collection module and analog-to-digital conversion module.Analog to digital conversion (ADC) inside modules is integrated constant current source, rail-to-rail Input Data Buffer, PGA (programmable gain amplifier), 24 ∑-Δ A/D converters and SPI interface controller etc.
The temperature signal collection module realizes through thermistor array is installed, and 36 thermistors and the electric resistance array that measuring resistance is formed has been shown, the temperature that can gather 36 control points at most among the figure.At first, the ADC chip is the constant current source that electric resistance array provides a stable 200uA, and this electric current is by master control module controls first multiway analog switch select in order to flow through measuring resistance and Ge Lu thermistor, through divider resistance ground connection.Thermistor high potential one end is imported anodal AIN+ end by predefined sampling rule by master control module controls gating and the analog quantity that is input to ADC through second multiway analog switch; Low potential one end also is a common port, receives the analog quantity input negative pole AIN-end of ADC.This voltage signal converts digital quantity to through 24 ∑s-Δ A/D again through ADC inner buffering and the amplification of PGA difference, is input to through the SPI interface and carries out data processing in the main control module and obtain thermistor digital quantity Nt.
Be parallel with the accurate resistance of a roadbed with thermistor, gather one road thermistor at every turn, gather the voltage at reference resistance two ends simultaneously.This reference resistance comes gating by first multiway analog switch equally, and the reference voltage signal that obtains is sent into ADC through second multiway analog switch, obtains reference resistance digital quantity Njz through the main control module data processing.Wherein, constant current source is I, and then the terminal voltage of Rt (thermistor) and Rjz (reference resistance) is respectively I * Rt, I * Rjz.
Vt＝I×Rt×A＝Nt×K
Vjz＝I×Rjz×A＝Njz×K
K is the reference current digital quantity.
Main control module is according to Nt and Njz, above two formulas ask ratio can obtain thermistor Rt (t=1,2 ...) and resistance, according to formula Rt=R * e
B * (1/T1-1/T2), can calculate the value of waiting to ask temperature T 1.Rt is that thermistor is in the resistance of waiting to ask temperature T 1 in the formula; R is the nominal resistance of thermistor under T2 normal temperature; The B value is the thermistor conversion coefficient, B=3950; Here to refer to the K degree be kelvin degree for T1 and T2, K degree=273.15 (absolute temperature)+degree centigrade.And because temperature collect module has adopted with reference resistance and has asked ratio to obtain the method for measured resistance; The value of The whole calculations processing procedure and constant current source is irrelevant; So the requirement to the accuracy of constant current source is not very high, only require that it has stability preferably, can guarantee precision like this.
Adopt two groups of multiway analog switches to realize obtaining of signal among Fig. 2, two groups of shared cover address wires of multiway analog switch.The thermistor that the first multiway analog switch gating will be gathered forms a constant current source acquisition circuit; Simultaneously the voltage signal of thermistor has been introduced ADC with second multiway analog switch of the shared identical address of first multiway analog switch.Because it is infinitely great that the input impedance of the differential amplifier that ADC is inner can be considered, the conducting internal resistance of second multiway analog switch just can have been ignored fully.Because acquisition circuit adopts constant current source; So the first multiway analog switch conducting internal resistance is to the not influence fully of thermistor voltage; And voltage signal is directly drawn by the thermistor two ends, has so just avoided the influence of multiway analog switch conducting internal resistance to the thermistor resistance fully.
