The specific embodiment
As Fig. 1, shown in 2, a kind of capsule endoscopic 30, comprise a capsule shape housing 11, housing 11 front ends are provided with the optics protecgulum 1 of transparent sealing, be provided with the imaging system that to take the body intracavity figure in the housing 11, can send the illuminator of illumination light working flare intracavity portion, power-supply system 7 to imaging system and illuminator power supply, image delivering system 10, the radio wakeup sleep system, radio-frequency recognition system and microprocessor 6, wherein imaging system and illuminator are collectively referred to as image capturing system, image capturing system and image delivering system 10 are collectively referred to as image acquisition transmission system 25, illuminator comprises white light LEDs 2 and infrared light LED13, be provided with visible light optical lens group 3 in the imaging system, infrared light optical lens group 14, lens bracket 4, visible light CMOS image sensor 5 and infrared light CMOS image sensor 12, the radio wakeup sleep system comprises the low-consumption wireless electricity receiver 17 that is positioned at housing 11 and is positioned at that housing 11 is outer to mate the controller 18 of sleeping that wakes up that is connected with low-consumption wireless electricity receiver by wireless signal, by the external duty of waking each system in sleep controller 18 and the low-consumption wireless electricity receiver 17 control capsule endoscopics up, radio-frequency recognition system comprises and is arranged at the RFID tag 29 in the housing 11 and is positioned at RF identification (RFID) label readers 26 that housing 11 is connected by radio-frequency match with RFID tag 29 outward, by the position of RF identification (RFID) label reader 26 detected RF identification (RFID) labels 29 capsule endoscopic is implemented accurate location.Visible light and infrared light optical lens group respectively have three, arrange according to leg-of-mutton mode respectively.Can certainly be for more than three, as arranging around mode, the optical lens group has the very-short-reach focal length to the optical lens group more than three by the angle of broadening one's vision.
As shown in Figure 3, low-consumption wireless electricity receiver 17 is based on the production technology of Low-Power CMOS, and framework and operating frequency by the optimal design wireless receiver further reduce the work power consumption.The low power dissipation design characteristics comprise high-gain low noise amplifier (Low Noise Amplifier), on-off keying modulation (On-Off Key) detector, Manchester's code.Low-consumption wireless electricity receiver 17 is avoided the phase mutual interference by using wireless tender's working frequency different with wireless image transfer of data in the image capturing system.Operation principle: start image acquisition transmission system 25 flow processs, when image acquisition transmission system 25 is in the low-power consumption resting state, wake sleep controller 18 wakes clock signal 20 up at low duty ratio (low duty cycle) control up and start down regularly 19 low-consumption wireless electricity receiver 17, whether detection antenna 15 receives the radio wakeup signal of extraneous specific coding.If do not detect the radio wakeup signal of specific coding, wake sleep controller 18 up and close low-consumption wireless electricity receiver 17 and save the energy, wait for that the next one wakes the clock cycle up and repeats above flow process.If, detect the radio wakeup signal of specific coding, wake sleep controller 18 up and send to image acquisition transmission system 25 and start image acquisition signal 23, the normal image acquisition of image acquisition transmission system 25 beginnings.Closing image acquiring and transmission system 25 flow processs, when image acquisition transmission system 25 is in normal image acquisition state, wake sleep controller 18 wakes clock signal 20 up at low duty ratio (low duty cycle) control up and start down regularly 19 low-consumption wireless electricity receiver 17, whether detection antenna 15 receives the radio sleep signal of extraneous specific coding.If do not detect the radio sleep signal of specific coding, image acquisition transmission system 25 is in normal image acquisition state.If, detect the radio sleep signal of specific coding, wake sleep controller 18 up and send to image acquisition transmission system 25 and stop image acquisition signal 24, image acquisition transmission system 25 stops normal image acquisition, and closing image collection transmission relevant device is saved the energy.
Among Fig. 3 15 for antenna, 16 for the Antenna Impedance Matching assembly, 17 for low-consumption wireless electricity receiver, 18 for waking the sleep controller up, 19 for the radio receiver enabling signal, 20 for wake up clock signal, 21 for the low-power consumption agitator, 22 for power supply and power management assembly, 23 be that system start-up image acquisition signal, 24 is an image acquisition transmission system for system stops image acquisition signal, 25.
RF identification (Radio Frequency Identification, RFID) as shown in Figure 4, being one utilizes radiofrequency signal to realize that by space coupling (alternating magnetic field or electromagnetic field) contactless information transmission and the information of passing through to be transmitted reach the technology of identifying purpose.The capsule endoscopic that has RF identification (RFID) label, both can help capsule endoscopic production, detect, circulation and the management that stores, also can under the support of computer-controlled external radio-frequency identification (RFID) label reader, finish the intravital accurate location that has the capsule endoscopic of RF identification (RFID) label to the patient, and then the image that capsule endoscopic is gathered is corresponding one by one in the position of human body with capsule endoscopic, and diagnostic message more accurately and effectively is provided.The location operation principle is: when the capsule endoscopic 30 that has RF identification (RFID) label is mobile in patient's digestive tract, produce induction according to 29 electromagnetic fields 28 that produce together with nearest external radio-frequency identification (RFID) label reader coil 27 of its RF identification of carrying (RFID) label of Faradic electricity magnetic induction principle (Faraday ' s principle ofmagnetic induction), and by label internal circuit canned data electromagnetic field 28 is modulated, corresponding in vitro RF identification (RFID) label reader 26 changes the information that RF identification (RFID) label carries that identifies by measuring electromagnetic field.RF identification (RFID) label reader communicates information to RF identification (RFID) label reader recording controller 32 via RF identification (RFID) label reader Data Control bus 31, thereby finishes the real-time positioning to the capsule endoscopic 30 that has RF identification (RFID) label.
