Amplifier in the present embodiment all uses the LM324 operational amplifier.General when removing the feedback resistance of amplifier, when feedback resistance is tending towards infinity in other words (open loop situations), think that in theory the open loop multiplication factor of amplifier also is infinitely great (being actually very big, is 100dB as LM324 amplifier open loop multiplication factor, both 100,000 times).This moment, amplifier just formed a voltage comparator, and its output is exactly low level (V-or ground connection) as being not high level (V+).When positive input voltage is higher than reverse input end voltage, the amplifier output low level.
Amplifier voltage amplification factor Av is only determined by outer meeting resistance Ri, Rf: Av=-Rf/Ri.Negative sign represents that output signal is opposite with the input signal phase place.Press the numerical value of giving among the figure, Ri=5 Europe, Rf=100 Europe, Av=-20.Be some small voltage Ugan=0.3mV of original transducer, then through twice amplification multiple be exactly 20X20=400 doubly, be Ugan '=0.12V, this circuit input resistance is Ri in this way.Get Ri generally speaking earlier and equate that with the signal source internal resistance multiplication factor as requested is at selected Rf then.Co and Ci are coupling capacitance.
As shown in Figure 1, use two amplifiers to form a voltage bound comparator, resistance R 1, R5 form bleeder circuit, for the positive input of amplifier Q1 is set comparative level U1; Resistance R 2, R6 form bleeder circuit, for the reverse input end of amplifier Q2 is set comparative level U2.For the output of amplifier Q3 is set comparative level U0.
Input voltage U1 is added between the reverse input end of the positive input of amplifier Q1 and amplifier Q2 simultaneously, and when U0>U1, amplifier Q1 exports high level; When U0<U2, amplifier Q2 exports high level.As long as amplifier Q1, amplifier Q2 have an output high level, diode L3 will conducting, and send signal to the mobile phone control chip this moment, will start systems such as missed call prompting.
If select U1>U2, then when input voltage U0 ran off [U2, U1] interval range, diode L3 was with regard to conducting, and this is the two limit indicating devices of a voltage.Will start systems such as missed call prompting.
If select U2>U1, then work as input voltage when [U2, U1] interval range, this is " window " voltage indicator.Diode L3 can conducting, and the information that the mobile phone control chip is received is low level, can not start missed call and remind.The bound voltage of window comparator is that reference voltage is respectively 3.5V and 1.2V, and comparative level U1 is 3.5V, and comparative level U2 is 1.2V, the also difference that can set according to own mobile phone, and design different voltage upper lower limit values.
The present invention mainly contains two parts and forms, and one is the infrared rays survey device, and one is the mobile phone control module.The infrared rays survey device mainly is the instruction of receiving the mobile phone control chip, and whether carry out has the crowd around the intelligent infra-red detection mobile phone, and result of detection is sent in the mobile phone control chip.Further operate for the mobile phone control chip.The infrared rays survey device mainly contains infrared acquisition control chip, infrared acquisition eye, transport module.
The infra-red detection control chip mainly is around surveying mobile phone by control infra-red detection eye whether the crowd to be arranged, and the numerical value of the detection of infra-red detection eye is sent to module such as mobile phone control chip by transport module.Also be controlled by simultaneously the instruction that the mobile phone control chip sends.It is the core component of infrared rays survey device.
The infra-red detection eye mainly is to be embedded in two sides of mobile phone, around the utilization infra-red detection principle mobile phone whether the crowd is arranged, and then result of detection is sent to the mobile phone control chip by transport module.Be controlled by and the infra-red detection control chip.
