Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a flowchart of a first embodiment of the present invention is shown, in which a data communication method of the present invention performs data communication in a manner of the same operating frequency and different bandwidths, when a capsule endoscope enters a human body in step 101, the capsule endoscope synchronously initializes a sensor and starts image capturing in step 102, step 103 further determines whether to start sending image data, and if it is determined that image data needs to be transmitted, step 104 performs broadband transmission of the image data; if the parameter information is judged to be transmitted, the parameter information is data with a data packet less than or equal to 1KB, at this time, step 105 starts narrow-band transmission, the parameter information is transmitted through a radio frequency unit, when the data is transmitted in step 104 or step 105, step 106 further judges whether the data transmission is finished, if the data transmission is finished, step 107 is entered, whether an external equipment control command needs to be received is judged, so that whether the operation parameter of the capsule endoscope needs to be adjusted is further judged, and if the external equipment control command needs to be received, step 109 receives and executes the external equipment control command, so as to adjust the operation parameter of the capsule endoscope; if step 107 determines that no external device control command needs to be received, then step 108 is entered to continue to capture image data and parameter information.
In the first embodiment, because of the limitation of the size of the capsule endoscope, the receiving sensitivity of the capsule endoscope is usually low, when the image receiving memory issues a command to the capsule endoscope, and the receiving sensitivity of the capsule can be improved by reducing the bandwidth under the condition that the receiving and sending links are the same, and the correct data receiving of the capsule can be better ensured; on the other hand, in an actual medical environment, since there may be a case that patients gather together for examination, for the image receiving memory, due to the improvement of the capsule sensitivity, under the condition that the capsule can normally receive, the transmitting power can be properly reduced, and the risk that the image receiving memory interferes with other devices is reduced, the receiving sensitivity S of the radio frequency unit adopts the formula: s = -174+10lgBW + NF + SNR, where BW denotes bandwidth, NF denotes noise figure, and SNR denotes signal-to-noise ratio.
In the first embodiment of the present invention, data communication is performed by using the same operating frequency and different bandwidths, for example, the operating frequency or the center frequency is set to 434MHz, the operating frequency band with a wideband bandwidth of 1MHz is 433.5 MHz-434.5 MHz, and the operating frequency band with a narrowband bandwidth of 100KHz is: 433.95MHz to 434.05 MHz.
Referring to fig. 2, a flowchart of a second embodiment of the present invention is shown, when data communication is performed with different operating frequencies and different bandwidths, because the frame rate of images captured by a capsule endoscope is usually between 2-35 fps, and the reading frequency of other sensors is very high, even data communication with an external magnetic control device needs to be performed in real time, at this time, data communication needs to be performed with different operating frequencies and different bandwidths, for example, a broadband transmission channel with a center frequency of 2.48GHz and a broadband bandwidth of 6MHz and a narrow band channel with a center frequency of 433.1MHz and a narrow band bandwidth of 100KHz are set, where the broadband operating frequency is 2.45 GHz-2.411 GHz and the narrow band is 433.05 MHz-433.15 MHz.
Particularly, in order to prevent the problem of adjacent channel interference and reduce the hardware design difficulty and cost, the communication method of the invention preferentially selects different frequency bands for data communication.
In step 201, initializing a capsule endoscope starting sensor and shooting an image, in step 202, starting to shoot the image and synchronously acquiring parameter information, wherein the parameter information is data with a data packet less than or equal to 1KB, then in step 203, judging whether the image data needs to be transmitted, if so, in step 204, setting the broadband center frequency to be f1, and starting to transmit the image data in broadband; if the step 203 judges that the parameter information needs to be transmitted, the step 205 is entered to start the narrow-band transmission parameter information, the narrow-band center frequency of the capsule endoscope is set as f2, in the process of transmitting the image data and the parameter information, the step 206 further judges whether the data transmission is finished, if the image data and the parameter information need to be continuously transmitted, the step 201 is returned to continue to carry out the acquisition of the image data and the parameter information; when the image data and the parameter information are judged to be completely transmitted, step 207 is entered, whether an external device control command is received or not is further judged, and if yes, step 209 receives the external device control command to adjust the running parameters of the capsule endoscope; if not, step 208 continues to perform image data and parameter information acquisition.
In particular, the bandwidth of the broadband in the first embodiment and the bandwidth of the narrowband in the second embodiment of the present invention are greater than or equal to 1MHz, and the bandwidth of the narrowband is less than or equal to 200 KHz.
Referring to fig. 3, a schematic diagram of serial data processing according to the present invention shows that a general capsule endoscope MCU is a serial processing mechanism, data of different sensors are read at different time points, a transmission time of the entire parameter information is T0= T0+ T1+ … … Tn, and a capsule endoscope has a low processing efficiency for image data and parameter information.
Referring to fig. 4, a schematic diagram of data parallel processing according to the present invention, in order to solve the deficiency of the serial processing mechanism, the MCU is set as the parallel processing mechanism, and compared with the serial processing mechanism, the time required for processing the same data amount is the longest processing time in each data packet, so as to meet the requirement of timeliness of the data of the capsule endoscope.
Referring to fig. 5, the capsule endoscope system of the present invention is schematically shown, and the capsule endoscope system of the present invention is composed of a capsule endoscope 10, an image receiving memory 20 and an image workstation 30, wherein the capsule endoscope 10 further includes an image sensor 1001, a magnetic sensor 1002, an IMU unit 1003, an MCU unit 1004 and a first RF transceiving unit 1005.
