POSITIONING SYSTEM, APPARATUS AND METHOD FOR ESOPHAGEAL PH VALUE WIRELESS MONITORING

摘要

The invention esophagus hydrogen exponent (pH) radio detection and positioning systems, relates to an apparatus and method, The system includes a recording device 20 transmits the detection in vitro and vivo sensing device 30; The body detected transmission device 30 includes the first device 307, the recording device is detected in vitro (20), the second device 203 is included, and; The first device 307 of the second device 203 and the body-sensing transmission unit 30 of the in vitro detection recording device 20 the mutual cooperation, if the in vitro detection recording device 20 detects a body transmission device 30 is given When detected that exceeds the range, the alarm buzzer sound signal under control of a microprocessor (201); Vitro detection recording device 20 collects the signal strength periodically for the second wireless transceiver module 204 receives a signal under the control of the microprocessor 201, if detecting that the signal strength exceeds a given signal strength range In one case, an alarm is sounded under the control of a microprocessor (201). ;
