With reference to Fig. 2, zone location and alarm principle schematic of crossing the border, positioning principle is realized by WiFi location technology, location cross the border alarm principle and step as follows:
(1) each wireless access points (AP) has a globally unique MAC Address, and wireless aps is changeless;
(2) mobile monitoring instrument can scan after powering on and connect AP signal, and gets the MAC Address that AP broadcasts out;
(3) mobile monitoring instrument by its connect AP MAC Address be sent to HC monitor system, HC monitor system retrieves the geographical position of each AP, and the geographical position of patient can be calculated in conjunction with the intensity of each signal, and by the position display of patient on electronic chart;
(4) AP arranging monitoring gateway, region is alarm AP, and when patient is movable in this AP, HC monitor system and trigger alerts, prevent patient to wander away.
The principle of fall detection: be provided with 3-axis acceleration sensor in the mobile monitoring instrument that patient carries with, three coordinates of sensor are corresponding with human body coordinate respectively, x-axis represents human body left and right directions acceleration change, y-axis represents the acceleration change of human body fore-and-aft direction, and z-axis represents the acceleration change of human body vertical direction.When people stand or walking states time, the acceleration of z-axis is close to g, and x-axis and y-axis acceleration are close to 0.When human body is in the process of falling down, the acceleration of three axles and vector thereof can change, and by setting certain threshold value, judge the acceleration change of three axis, judge whether patient falls down.
With reference to figure 3, fall detection algorithm flow chart, wherein freely falling body interrupts for when accekeration is lower than certain threshold value and when being continued above the regular hour, freely falling body interruption set; Interrupting movement is when accekeration exceedes certain threshold value, interrupting movement set; Static interruption for when accekeration is lower than certain threshold value and when being continued above certain hour, static interruption set.Fall detection algorithm steps is as follows:
(1) weightlessly to detect: in the process of patient falls, there is weightlessness, acceleration and be less than 1g, utilize freely falling body to interrupt judging the Weight lose that patient falls in process, using this first basis for estimation as the state of falling down;
