As can be seen from Figure 2, DSP (digital signal processor) signal processing system, the temperature/pressure sensor driving detection procedure, microwave transceiver, microwave switch aerial array, detection module and liquid-crystal display section is comprised according to the system for detecting blood sugar of the embodiment of the present invention.
Wherein, DSP signal processing system is the control core of whole system, wherein mainly include a kind of dsp chip (being TMS320F2812 chip in this example), clock circuit, reset circuit, voltage adjuster, JTAG (joint test behavior tissue) interface, program storage and data storage etc., wherein dsp chip is integrated with abundant On-Chip peripheral, such as SPI (Serial Peripheral Interface (SPI)), ADC (Analog-digital Converter) etc.
Wherein, as can be seen from Figure 2, DSP processing system is connected with temperature/pressure sensor by I/O interface; Be connected with microwave transceiver by SPI interface; Be connected with detection module by AD interface; Be connected with LCDs by control line.
In addition, microwave transceiver is also connected with detection module with microwave switch aerial array respectively.
Concrete, in the present embodiment, what temperature/pressure sensor adopted is contact temperature sensing, when the temperature/pressure sensor in system for detecting blood sugar of the present invention touch detection bodies surface create pressure and with temperature signal time, this pressure and temperature signal will be sent to DSP processing system by I/O interface; Then DSP processing system will be started by SPI Interface Controller microwave transceiver; Then microwave transceiver will send microwave sounding signal to microwave switch aerial array to carrying out blood sugar test, the concrete interaction flow of microwave transceiver and microwave switch aerial array then as shown in Figure 3:
In order to avoid under same blood sugar concentration, microwave frequency is on the impact of Microwave Impedance size, thus ensure the accuracy of microwave blood sugar test, in the present embodiment, microwave transceiver can provide the microwave of three frequencies to microwave switch aerial array, and the microwave of these three frequencies is continuous wave, wherein, these three optional frequencies are from the frequency range of 20GHz-100GHz, also can be selected from the frequency range of 40GHz-100GHz, preferably, the frequency range of 40GHz-60GHz can be selected from, in this example, microwave transceiver is selected from 40GHz-60GHz to the continuous wave frequency of three frequencies that microwave switch aerial array sends, wherein each frequency of microwave transceiver in these three frequencies all can export the microwave sounding signal of the continuous wave of few tens of nano-seconds time span (i.e. scheduled time length).
As can be seen from Figure 3, oscillator unit, converter unit (the first converter unit is identical with the second converter unit), coupler unit (the first bonder is identical with the second bonder), mixing unit (the first frequency mixer is identical with the second frequency mixer), quadrature demodulator, data acquisition unit and timing control unit is comprised according to the microwave transceiver of the embodiment of the present invention, wherein, timing control unit controls the length of run of the said units element of microwave transceiver inside, namely carries out sequencing contro to each element of microwave transceiver inside.
So specific to the above-mentioned concrete steps in blood sugar detecting method, microwave transceiver is after the enabled instruction receiving DSP processing system, three tunnel microwave sounding signals of above-mentioned three frequencies can be sent to microwave switch aerial array simultaneously, blood sugar test is completed again by microwave switch aerial array, because the generation of each road microwave sounding signal is identical with process, therefore, the idiographic flow that below, Zhi Yi mono-tunnel microwave sounding signal realizes blood sugar test is described in detail.
First, microwave transceiver is after the enabled instruction receiving DSP processing system, in order to send the microwave sounding signal of a road characteristic frequency, first can be divided into two-way by the agitator output reference time signal shown in Fig. 3 and sending to the first converter unit and the second converter unit.
