Description
Technical field
The present invention relates to location and navigation technology fields, are a kind of tracking bracelets for indoor positioning navigation specifically.
Background technology
Inside hospital, be no lack of be mentally ill patient or patients of senile dementia etc. some do not have complete behavior energy
The people of power, and these patients have ability to act, it is possible to exist and walk out ward and but can not find road or even Go out of Hospital back
Dangerous situation, and in this case, hospital generally uses hospital staff's nurse and monitoring device to check patient
Whereabouts, due to medical and nursing work, personnel are limited, and energy is limited, and nurse in 24 hours can not be carried out to patient, often can not find
The case where patient, can just go checking monitoring, therefore adopt remedial measures in the presence of lag, also, if patient walks out monitoring range,
For the patient that goes astray from the group of searching, increase difficulty, simultaneously because the health status of patient itself, for patient health not
It can continue to monitor, therefore the health and safety of patient cannot be guaranteed.
Invention content
The purpose of the present invention is to provide a kind of tracking bracelets for indoor positioning navigation, for solving in the prior art
Gerontal patient go astray from the group from hospital ward can not continue monitor patient health status, can not find in time patient body situation and and
When solution of emergent event the problem of.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
A kind of tracking bracelet for indoor positioning navigation, including arm processor, the voice mould that is connect with the arm processor
Block, memory module, locating module, GPRS module and display screen, the arm processor are also associated with for detecting health shape
The monitoring modular of condition, the monitoring modular include the heart rate pulse chip for acquiring heart rate, the heart rate pulse chip it is defeated

Monitoring modular further includes the pulse wave blood pressure sensor for acquiring blood pressure, the pulse wave blood pressure sensor at the ARM
Manage device connection.
Operation principle：
ARM processing is used as master controller, the server communication in model ARM740T, with the positioning system in hospital building, control
It locating module and is communicated with the base station used for positioning being arranged in hospital building, accurately calculated residing for tracking bracelet
Position, that is, wear tracking bracelet the location of patient.Electronic map is installed soft in arm processor in embedded system
Part, and show that the current position of patient, patient can be inputted oneself by voice module and want return by the display screen of connection
Place, arm processor pass through built-in routing algorithm, give Path selection, and show the route of return over the display, and
During return, if off-track, alarm is sent out by voice module, reminds patient.Arm processor can also lead to
Cross GPRS module, carry out the alarm call for dialing hospital internal, when patient goes astray from the group, can by the button in GPRS module,
Actively send distress signal.When the scope of activities of patient exceeds safe range, that is, exceeds the electronics set in electronic map and enclose
When column, arm processor driving voice module gives a warning.Within the time that patient walks out ward, due to the tracking of patient's wearing
The monitoring module being arranged on bracelet can acquire the blood pressure and heart rate of patient in real time, monitor the health status of patient, heart rate in real time
Pulse chip acquires beats, and analog signal is converted to digital signal after data processing circuit, inputs ARM processing
Device, by heart rate value is calculated, pulse wave blood pressure sensor is traced using photo-electric volume pulsation wave（PPG）Mode incude
The pulse wave information of human body is simultaneously extracted, and finally exports pulse waveform, therefore can monitor the fingers such as the blood pressure of patient, heart rate
Mark, then indication information is transmitted to by the server in hospital building by GPRS module by arm processor, realize heart rate and blood pressure
The output of numerical value, and can be shown by display screen.Therefore, even if patient is far from ward, before finding patient, still can lead to
The data checked on server are crossed, learn the health states of patient at this time, therefore, when patient is reasonable in hospital building
It when region is walked about, as long as not going to danger zone, need not interfere, therefore can allow patient that there is large range of work
Dynamic space.
Further, the locating module is using any one in UWB locating modules, WIFI locating modules or bluetooth.

Using register, most data manipulations are all completed in a register, and instruction execution speed is faster；Addressing system is flexibly simple, holds
Line efficiency is high.Peripheral Interface includes display interface and serial line interface.
Further, the heart rate pulse chip uses HRB6708.
Operation principle：
MKB0706 realizes Automatic-falling detection, the no data that falls off output, and automatic skin color model, rate pressure acquisition are calculated, exhaled
The human bodies health indicators such as suction rate, ecg information collection, body surface temperature monitoring, blood pressure tracking and monitoring.
Further, the pulse wave blood pressure sensor uses YKB1712.
YKB1712 pulse wave blood pressure sensor chip interiors integrate high-tech nano coating environment light detecting sensors, mistake
Unwanted light source to be filtered, reduces and is acted by the erroneous judgement that other light sources interfere, accuracy is high, coordinates HRB6708 heart rate pulse chips,
It can accomplish accurately heart rate and pulse wave monitoring, directly to export square-wave signal and pulse wave signal, client be facilitated to use.
Compared with prior art, the present invention haing the following advantages and advantageous effect：
（1）It, still can be by checking the number on server before finding patient even if patient is far from ward in the present invention
According to, learn the health states of patient at this time, therefore, when reasonable region of the patient in hospital building is walked about,
Danger zone is not gone to, need not be interfered, therefore can allow patient that there is large range of activity space.
（2）When patient can not find the route of return, the place to be returned, voice can be said with voice command is sent out
After collecting unit receives order, after amplifying circuit is by signal amplification, filter circuit filtering clutter, ARM processing is inputted
