Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
FIG. 1 is a schematic diagram of the configuration of a capsule endoscopic system, including a capsule endoscope and a portable recorder communicating via wireless technology, and further including a computer and positioning capsule endoscope software. According to the instruction issued by the portable recorder, the capsule endoscope collects images in the alimentary canal in real time and sends the images to the portable recorder by using 2.4G wireless communication. The portable recorder then transmits the data to the positioning capsule endoscopy software on the computer for processing and display.
Wherein, the communication between the capsule endoscope and the portable recorder is completed through a customized communication protocol. As shown in fig. 2, the capsule endoscope sends handshake request information at a predetermined frequency and rate, and the portable recorder to be communicated with the capsule endoscope is also set at the same frequency and rate and in a receiving mode. When the portable recorder receives the handshake request, it replies a working instruction to make the capsule endoscope enter into working state, the working instruction can be the result of reading the information of the capsule endoscope, writing the information into the capsule endoscope, commanding the capsule endoscope to store the information, configuring the image mode and requiring the capsule endoscope to output an image, etc., the capsule endoscope executes the working instruction after receiving the working instruction and replies the working instruction.
According to the above process, when only one capsule endoscope communicates with the portable recorder, the portable recorder can work smoothly, but if the same frequency or adjacent frequency equipment (whether the portable recorder or the capsule endoscope) works around, the portable recorder may receive the information of other capsule endoscopes to cause misjudgment of the portable recorder, or the capsule endoscope sends the information to other portable recorders to cause information loss.
In addition, the capsule endoscope is powered by a battery, the digestive tract of a human body is long, the capsule endoscope needs to continuously shoot for more than 10 hours in order to collect complete image information of the digestive tract, and how to shoot as many images as possible by using limited electric quantity to the maximum extent is also an important problem to be solved at present.
In order to solve the problems, the invention provides a communication method of the capsule endoscope system, in the method, the portable recorder and the capsule endoscope carry out identity matching through a handshake request, the image transmission can be carried out only if the matching is successful, otherwise, the image transmission cannot be carried out, so that the misjudgment or the information loss is reduced, and the power consumption of the capsule endoscope after the matching is failed is also reduced; meanwhile, the portable recorder can detect interference and dynamically adjust the frame rate of the capsule endoscope and the packet length for sending image data after successful matching, so that the working efficiency of the capsule endoscope is improved.
As shown in fig. 3, the communication method is applied to the portable recorder, and includes:
step S110: inputting the exclusive identity information of the paired capsule endoscopes.
Each capsule endoscope contains a built-in EEPROM for recording some specific information. The invention stores a piece of exclusive identity information in the EEPROM of each capsule endoscope, the information is not repeated, and the exclusive identity information stored by different capsule endoscopes is different. For the portable recorder, medical record input is needed before the examination is started, and the medical record input is the process that the upper computer software writes information such as examination type information, doctor information, patient information, exclusive identity information of the capsule endoscope and the like into the portable recorder through a USB interface. After a doctor takes the capsule endoscope, the external packaging box of the doctor is printed with the exclusive identity information of the capsule endoscope, and the doctor can record the exclusive identity information of the capsule endoscope into the portable recorder when recording medical records.
It should be noted that, when the medical record is recorded, the portable recorder is further provided with a fault-tolerant mechanism, that is, if a doctor wrote the exclusive identity information of the corresponding capsule endoscope during recording, the exclusive identity information received after the portable recorder starts to work is inconsistent with the recorded exclusive identity information, the portable recorder transmits the exclusive identity information to the upper computer, and the upper computer asks the user not to establish connection with the capsule endoscope and updates the exclusive identity information recorded by the portable recorder. The error information manually input can be corrected through the fault-tolerant mechanism.
Step S120: after receiving a handshake request of the capsule endoscope, judging whether the exclusive identity information carried in the handshake request is matched with the input exclusive identity information.
The handshake request of the capsule endoscope comprises the exclusive identity information thereof, and whether the exclusive identity information is matched with the exclusive identity information recorded in the portable recorder or not is judged.
It should be noted that, after receiving the handshake request, the portable recorder performs CRC16 check, where the CRC16 check is a check carried by the wireless communication protocol itself, and under the condition that the CRC16 check code is correct, it can be ensured that the received information is true and authentic without error codes, and since the CRC16 check is the prior art, it is not described herein again. And then the special identity information matching check is carried out after the CRC16 check is passed.
Step S130: and if so, issuing a working instruction comprising at least one task to the capsule endoscope, wherein if the signal quality of the current working frequency is detected to be out of a normal range, the working instruction comprises a task of dynamically adjusting the frame rate of the capsule endoscope and/or the packet length for sending image data according to the signal quality.
If the exclusive identity information is matched, the work instruction can be packaged, and the packaged work instruction can be issued to the capsule endoscope. Wherein the work order includes at least one task, such as requiring the capsule endoscope to output an image, and the portable recorder detects whether the signal quality of the current work frequency is within a normal range during the packaging process. Specifically, the signal quality is detected by detecting the signal-to-noise ratio of the current operating frequency. And if the signal quality of the current working frequency is detected to be out of the normal range, encapsulating a task of adjusting the frame rate of the capsule endoscope and the packet length of the transmitted image data into a working instruction.
Specifically, when the signal quality is lower than the normal range, the anti-interference capability of the communication signal is enhanced by reducing the packet length of the image data transmitted by the capsule endoscope. When the signal quality is higher than the normal range, the wireless transmission rate is increased by increasing the packet length of image data transmitted by the capsule endoscope, so that the frame rate can be increased and the power consumption can be saved (the larger the effective information amount transmitted by one wireless packet is, the higher the throughput rate is). In addition, the operation of the capsule endoscope can be improved correspondingly by adjusting the frame rate of the capsule endoscope, and specifically, the frame rate is determined by the operation time and the sleep time of each period of the capsule endoscope, and the operation time is relatively stable, so the frame rate is adjusted mainly by adjusting the sleep time, wherein the sleep time is the time interval between the operation ending time of the previous period and the operation starting time of the next period.
It should be noted that the two schemes of adjusting the frame rate of the capsule endoscope and adjusting the packet length of the image data transmitted by the capsule endoscope may be simultaneously implemented, or only one of the schemes may be separately implemented.
Therefore, in a specific embodiment, the "dynamically adjusting the frame rate of the capsule endoscope and/or the packet length of the transmitted image data according to the signal quality" specifically includes:
after the signal quality is lower than the lowest value of a normal working range, enhancing the anti-interference capability of the signal by reducing the packet length of image data sent by the capsule endoscope, and/or adjusting the frame rate of the capsule endoscope by prolonging the next sleep time of the capsule endoscope; after the signal quality is higher than the highest value of the normal working range, the wireless transmission rate is increased by increasing the packet length of image data transmitted by the capsule endoscope, and/or the frame rate of the capsule endoscope is adjusted by shortening the next dormancy time of the capsule endoscope.
When the signal quality is lower than the lowest value of the normal working range, the signal quality is relatively poor at the moment, the anti-interference capability of the signal is enhanced by reducing the packet length of image data transmitted by the capsule endoscope, and the interference in the period is avoided by prolonging the sleep time. In addition, when the interference is caused by other similar devices with the same frequency, the communication time of other devices can be staggered by prolonging the sleep time, so that the aim of improving the working efficiency of the capsule endoscope is fulfilled.
If the current signal quality is detected to be higher than the highest value of the normal working range, the wireless transmission rate is increased by increasing the packet length of the image data transmitted by the capsule endoscope, and in addition, the frame rate of the capsule endoscope can be adjusted by shortening the sleep time.
Further, the working instruction also comprises exclusive identity information of the capsule endoscope. After the capsule endoscope receives the working instruction replied by the portable recorder, matching and checking of the exclusive identity information are firstly carried out, and only after the checking is passed, the task in the working instruction is executed and the execution result is returned.
In a preferred embodiment, the method further comprises:
and discarding the handshake request after the handshake request of the capsule endoscope is received and the exclusive identity information carried in the handshake request is not matched with the input exclusive identity information.
In one embodiment, the portable recorder records the exclusive identity information of the corresponding capsule endoscope and configures the same working frequency as the capsule endoscope. After the capsule endoscope sends a handshake request, the portable recorder verifies whether the exclusive identity information carried by the handshake request is matched with the input exclusive identity information. And if the current working frequency is detected to be out of the normal range, the working instruction further comprises tasks of adjusting the frame rate of the capsule endoscope and transmitting the packet length of the image data. And if not, discarding the handshake request and waiting for the next handshake request.
The invention also provides a portable recorder which comprises a first memory and a first processor, wherein the first memory stores a first computer readable program which can run on the first processor, and the first processor executes the first computer readable program to realize the steps in the communication method of the capsule endoscope system applied to the portable recorder.
As shown in fig. 4, the present invention also provides a communication method of the capsule endoscope system, which is applied to the capsule endoscope, and includes:
step S210: after the wake-up time comes, a handshake request carrying the exclusive identity information of the other equipment is broadcasted to the other equipment through a preset working frequency.
The capsule endoscope works periodically, each period comprises working time and sleeping time, the capsule endoscope enters the sleeping mode after the working is finished, and the capsule endoscope is awakened after the sleeping is finished. When the awakening time of the capsule endoscope arrives, a handshake request is broadcasted to other equipment through the preset working frequency. The corresponding portable recorders are also set at the same operating frequency, so that the corresponding portable recorders can also receive the handshake request, and after the matching with the dedicated identity information in the handshake request is successful, issue a working instruction to the capsule endoscope, which may be referred to in the foregoing.
Step S220: after receiving the working instruction replied by the corresponding portable recorder, judging whether the exclusive identity information carried in the working instruction is matched with the exclusive identity information of the working instruction.
The capsule endoscope also needs to verify the identity matching of the work order.
Step S230: and if the task in the work instruction is executed, returning the result to the portable recorder, wherein if the task for adjusting the frame rate and/or adjusting the packet length for sending the image data is included in the instruction, the frame rate is adjusted and/or the packet length for sending the image data is adjusted according to parameters carried in the task.
And if the identity matching check is passed, analyzing the task in the working instruction and executing the task, and finally returning the result to the portable recorder. If the work instruction comprises a task for adjusting the frame rate, the frame rate is adjusted according to parameters carried in the task. Specifically, the parameter carried in the task is sleep time T of the capsule endoscope, and after the T is obtained from the task, the sleep time of the task is set to be T.
And if the work instruction comprises a task for adjusting the packet length of the image data, adjusting the packet length of the image data according to the packet length data carried in the task. When the signal quality is lower than the normal range, the anti-interference capability of the communication signal is enhanced by reducing the packet length of the image data transmitted by the capsule endoscope. When the signal quality is higher than the normal range, the wireless transmission rate is increased by increasing the packet length of image data transmitted by the capsule endoscope, so that the frame rate can be increased and the power consumption can be saved (the larger the effective information amount transmitted by one wireless packet is, the higher the throughput rate is).
It should be noted that the work instruction may include both the task of adjusting the frame rate and the packet length of the transmitted image data, or may include only one of the tasks.
In order to minimize the power consumption of the capsule endoscope (a reduction in power consumption means that more active pictures can be taken), in a preferred embodiment the method further comprises:
and after receiving a working instruction replied by the portable recorder and the exclusive identity information carried in the working instruction is not matched with the exclusive identity information of the portable recorder, discarding the working instruction, entering dormancy, and sending a handshake request after waiting for the next wakeup time.
In the prior art, after the capsule endoscope receives the replied work instruction, the identity matching check of the work instruction is not performed, only the CRC16 check carried by the communication protocol is performed, and as long as the CRC16 check passes, the task in the work instruction is executed and the result of the task is replied. According to the invention, after the identity matching fails, the working instruction is directly discarded, so that misjudgment or information loss can be reduced, and the power consumption of the capsule endoscope can be greatly saved. And after the identity matching fails, a sleep mode is carried out to avoid the interference of the period of time, and a handshake request is sent after the next wakeup time comes.
In a specific embodiment, the capsule endoscope sends a handshake request carrying exclusive identity information after the wakeup time comes. After receiving a working instruction, checking whether the exclusive identity information carried in the working instruction is matched with the exclusive identity information of the working instruction, if so, executing a task in the working instruction, and if not, discarding the working instruction, entering a sleep mode, and waiting for the arrival of the next awakening time.
