Description

For controlling the method for transmitting power in capsule endoscope system

Technical field

The invention belongs to communication technical field, particularly relating to a kind of method for controlling transmitting power in capsule endoscope system.

Background technology

Along with the prosperity of the continuous progressive and medical skill of science and technology, capsule endoscope is also constantly used in the treatment of various intestinal tract disease, detect.In prior art, when real time monitoring is carried out to capsule endoscope, first adjust memory-aided data by the processor of capsule, and then by the capsule method for reading data passing to host computer of wireless signal or data wire in form.The wireless signal sent due to capsule is very unstable, and in existing capsule endoscope system, cannot received signal strength be judged and the transmitting power of capsule is controlled, therefore existing capsule endoscope transmit data by wireless transmission method and have that efficiency is low, the serious and shortcoming that data transmission is unstable of power wastage, capsule endoscope system is used and brings great impact.

Therefore those skilled in the art are devoted to develop a kind of method that can control capsule endoscope system transmitting power.

Summary of the invention

Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of method controlling capsule endoscope system transmitting power.

For achieving the above object, the invention provides a kind of method for controlling transmitting power in capsule endoscope system, comprising the following steps:

Data to be sent are divided into n packet by step one, capsule endoscope, and n is positive integer; Described capsule endoscope by each Packet Generation to image recorder;

The antenna sets of step 2, described image recorder receives the packet that described capsule endoscope sends;

Step 3, judge that whether the packet that the antenna of described image recorder receives is complete; When the packet that described image recorder receives is complete, perform step 4; When the packet that described image recorder receives is imperfect, the processor of described image recorder transmits control signal to described capsule endoscope, and controlling described capsule endoscope increases transmitting power, then returns execution step 2;

The antenna that described in step 4, setting procedure three, receives data packets is complete is optimal antenna, judges whether the signal intensity of this optimal antenna is greater than the maximum signal value of setting; When the signal intensity of described optimal antenna is greater than maximum signal value, perform step 5; Otherwise return after the data that described optimal antenna receives are preserved and perform step volume;

Step 5, the data that described optimal antenna receives are preserved after, the processor of image recorder transmits control signal to capsule endoscope, control capsule endoscope reduce transmitting power, then return execution step 2.

Adopt the transmitting power of above technical scheme to capsule endoscope to control, capsule power consumption can better be controlled, thus reach the best working time.

Further, control in described step 5 also to comprise the step judging whether packet receives completely after capsule endoscope reduces transmitting power; Terminate when packet receives completely; When packet does not receive completely, return execution step 2.

Further, the step judging whether packet receives completely is also comprised after the data that described optimal antenna receives being preserved in described step 4; Terminate when packet receives completely; When packet does not receive completely, return execution step 2.

The invention has the beneficial effects as follows: the present invention is by judging that capsule endoscope sends the intensity of signal, find out a Received signal strength the strongest, and adjust transmitting power according to this signal intensity, what can ensure the data fast and stable of capsule endoscope is transferred to image recorder.Simultaneously by controlling the transmitting power of capsule endoscope, capsule power consumption can better be controlled, thus reach the best working time.

Fig. 1 is the schematic flow sheet of the embodiment of the invention.

Detailed description of the invention

Below in conjunction with drawings and Examples, the invention will be further described:

As shown in Figure 1, a kind of method for controlling transmitting power in capsule endoscope system, is characterized in that comprising the following steps.

Data to be sent are divided into n packet by step one, capsule endoscope, and n is positive integer; Described capsule endoscope by each Packet Generation to image recorder.

The antenna sets of step 2, described image recorder receives the packet that described capsule endoscope sends.

Step 3, judge that whether the packet that the antenna of described image recorder receives is complete; When the packet that described image recorder receives is complete, perform step 4; When the packet that described image recorder receives is imperfect, the processor of described image recorder transmits control signal to described capsule endoscope, and controlling described capsule endoscope increases transmitting power, then returns execution step 2.

The antenna that described in step 4, setting procedure three, receives data packets is complete is optimal antenna, judges whether the signal intensity of this optimal antenna is greater than the maximum signal value of setting; When the signal intensity of described optimal antenna is greater than maximum signal value, perform step 5; Otherwise perform step 6 after the data that described optimal antenna receives being preserved.

Step 5, the data that described optimal antenna receives are preserved after, the processor of image recorder transmits control signal to capsule endoscope, control capsule endoscope reduce transmitting power, then perform step 6.

Step 6, judge whether packet receives completely; Terminate when packet receives completely; When packet does not receive completely, return execution step 2.In the present embodiment, maximum signal value and described

The signal intensity setting threshold value of excellent antenna is the artificial setting according to practical situation, and described setting threshold value is real number, more than describes preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
