Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
In the present invention, a patient position tracking system is provided, as can be seen in fig. 1, and the system includes a monitoring terminal 10, a positioning terminal 20, a positioning base station 30 and an electronic fence 40.
The monitoring terminal 10 constructs a corresponding monitoring area, in which a plurality of positioning base stations 30 are disposed for positioning a plurality of positioning terminals 20 located in the monitoring area, and the electronic fence 40 includes a plurality of edge detection modules 41 for detecting whether the plurality of positioning terminals 20 cross the monitoring area; here, "over the area" indicates a state in which the positioning terminal 20 moves outside the monitoring area and cannot be positioned by the positioning base station 30.
Specifically, the method comprises the following steps:
the positioning base station 30 is in communication connection with the positioning terminal 20; the positioning base station 30 is preset with calibration information, the calibration information includes a preset position and a preset positioning height of the positioning base station 30, and the positioning base station 30 is used for positioning the positioning terminal 20 within the preset positioning height in real time and transmitting the real-time positioning position to the positioning terminal 20 in a communication manner;
the positioning terminal 20 is worn on a patient and is in communication connection with the monitoring terminal 10, the positioning terminal 20 includes a position processing module 21, and the positioning terminal 20 is configured to process a real-time positioning position through the position processing module 21 and transmit a processing position communication to the monitoring terminal 10.
Specifically, during positioning:
assuming that the preset position of the positioning base station a 30 is a layer a, and the preset positioning height is 0-h, the positioning base station a 30 only positions the positioning terminal 20 within the height of 0-h; assuming that the preset position of the B positioning base station 30 is at three layers B, and the preset positioning height is 2h-3h, the B positioning base station 30 only positions the positioning terminal 20 within the height of 2h-3 h.
One positioning terminal 20 is in communication connection with at least three positioning base stations 30, and after connection, the positioning base stations 30 can obtain the current distance between the positioning terminal 20 and the connected positioning terminal through a distance positioning module 31; after the current distance is determined, the real-time positioning position corresponding to the positioning terminal 20 can be generated by the position generating module 32 in the positioning base station 30, specifically, the real-time positioning position is a position range in which the positioning base station 30 is a circle and the current distance is a radius. For example, in fig. 3, a dashed circle indicates a position range (real-time positioning position) formed by each positioning base station 30 for the positioning terminal 20 positioned by the positioning base station.
After the at least three positioning base stations 30 complete the real-time positioning, the generated real-time positioning positions are acquired by the corresponding positioning terminals 20 through communication transmission. The positioning terminal 20 acquires at least three real-time positioning positions, and integrates the at least three real-time positioning positions through the position processing module 21; the specific finishing principle is as follows: determining an intersection point of at least three real-time positioning positions (position ranges), and taking the intersection point as an integrated processing position of the positioning terminal 20; the positioning terminal 20 also transmits the integrated processing position communication to the monitoring terminal 10, so that the monitoring terminal 10 can accurately acquire the spatial position of the positioning terminal 20.
Regarding the monitoring terminal 10, a display module 11 is included, and the monitoring terminal 10 is configured to display the integrated processing position of the positioning terminal 20 through the display module 11.
Example two
This embodiment is a further preferred embodiment of the first embodiment, and the present embodiment adds a dynamic monitoring and alarm function on the basis of the first embodiment, and the specific structure for implementing this function is as follows.
The positioning terminal 20 further includes a motion monitoring module 22, a heart rate monitoring module 23, a blood pressure monitoring module 24, a matching module 25, a judging module 26 and a first alarm module 27 besides the structure disclosed in the first embodiment. Specifically, the method comprises the following steps:
the motion monitoring module 22 is used for collecting motion information of a patient wearing the positioning terminal 20;
the heart rate monitoring module 23 is used for collecting heart rate information of a patient wearing the positioning terminal 20;
the blood pressure monitoring module 24 is used for collecting blood pressure information of a patient wearing the positioning terminal 20;

the judgment module 26 is used for judging whether the heart rate information and the blood pressure information are in a reasonable heart rate range and a reasonable blood pressure range;
the first alarm module 27 is used for executing a first alarm on the positioning terminal 20 when the judgment result is negative, and communicating and transmitting first alarm information to the monitoring terminal 10; wherein the monitoring terminal 10 also performs the first alarm after receiving the first alarm information.
Specifically, if the motion monitoring module 22 monitors that the motion information moves at a low speed, the matching module 25 obtains a reasonable heart rate range and a blood pressure range corresponding to the low speed according to the moving speed, and the determining module 26 determines whether the heart rate information and the blood pressure information monitored by the heart rate monitoring module 23 and the blood pressure monitoring module 24 are in the matched reasonable range, if yes, no alarm is executed, otherwise, an alarm is executed. Take patient's fall down as an example, patient's motion state stops after falling down, and rhythm of the heart and blood pressure then can rise rapidly, then can make the motion information of monitoring mismatch with rhythm of the heart information and blood pressure information from this to carry out accurate alarm.
In addition, the electronic fence 40 further includes a second alarm module 42, and the electronic fence 40 is configured to communicate and transmit second alarm information to the monitoring terminal 10 and the locating terminal 20 through the second alarm module 42 when the locating terminal 20 is beyond the area; and both the positioning terminal 20 and the monitoring terminal 10 perform the domain crossing alarm after receiving the second alarm information.
