Reference voltage.Amplifier 11 is a road built-in amplifier of TLC2274, and it is connected into the form of voltage follower, and resistance 272 and resistance 273 resistances equate that the output of amplifier equals to be the positive input magnitude of voltage, so reference voltage equals
Electric capacity 274 and electric capacity 275 have played filter action, have reduced the noise on the output reference voltage.In the description of Electronic bubble, an Electronic bubble sensor comprises the angle signal output of three directions before, and module 28, module 29, module 30 are the photodiode output signal conditioning circuit, three module connection unanimities.In module 28, two infrared photodiode 14 reverse parallel connections, output current signal, amplifier 281 is designed to the I-V change-over circuit, is used for current signal is converted to voltage signal output.When the current source output current of two infrared photodiodes 14 compositions was zero, the voltage of amplifier 281 outputs was
When instrument was not in the equilibrium position, the current source output current of two infrared photodiode 14 compositions was non-vanishing, and output voltage is:
The zeroing end of the electric current that resistance 284, slide rheostat 285, resistance 286 constitute.When instrument was in the equilibrium position, if the current source output current of two infrared photodiode 14 formations is non-vanishing, then circuit output voltage this moment was not
, need to regulate slide rheostat 285, change output voltage, output voltage is become
Module 31 is the power pack of infrared LED, and an Electronic bubble needs three infrared LEDs.Each LED just is being connected to VCC, and negative terminal is connected to resistance 311, resistance 312, resistance 313 respectively.Whether triode 317 is used for control LED works, and slide rheostat 314, slide rheostat 315, slide rheostat 316, the luminous intensity that can regulate infrared LED pipe 318, infrared LED pipe 319, infrared LED pipe 320.The sensitivity of infrared LED luminous intensity and Electronic bubble has direct contact.
