Novel data are received and transmitting circuit device

The utility model discloses a novel data are received and transmitting circuit device. Including FSK demodulation circuit, phase discrimination circuit, isolation and snubber circuit, singlechip U3, serial ports level shifting circuit and COM-USB converting circuit, its characterized in that, singlechip U3's input passes through FSK demodulation circuit electricity and connects the spy spigot end of pipe to gather the signal of visiting pipe inner sensor, and rotary encoder still is connected through isolation and snubber circuit, phase discrimination circuit electricity to singlechip U3's input, thus the data that make singlechip U3 receive two passageways, and reconfiguration cheng xin's data frame, the output of singlechip passes through serial ports level shifting circuit and COM-USB converting circuit connection host computer. Adopt rotary encoder among this novel circuit arrangement, bring up to 300 pulses of 0.67 meter usefulness with the resolution ratio of degree of depth signal by 1 meter 3 pulse signal and express for measured data is more accurate.
