The described monitoring terminal inside of the embodiment of the invention, the sensor that is used to detect monitored target body movement state is the three-axis acceleration sensor (hereinafter to be referred as MMA7260QT) of Freescale (Freescale) company preferably, MMA7260QT has three axial inducing functions, current drain only is 500 μ A during work, current drain 3 μ A under the park mode state, and can under 2.2 to 3.6V low-voltage, move.
As shown in Figure 3, the workflow of described monitoring terminal as follows: after the described monitoring terminal initialization, scanning channel, and join in the ZigBee wireless network of setting up described telegon base station, obtain 16 network addresss, meeting display menu on the described display screen of described monitoring terminal, after clicking " connection network ", binding relationship is set up in described monitoring terminal and described telegon base station, after clicking " transmission data ", monitoring terminal begins to carry out the detection of condition, read the 3-axis acceleration data of acceleration transducer MMA7260QT every certain interval (for example 0.5 second), and carry out the AD conversion, obtain the condition of monitored target by the judgement of sorter, and judge whether identical with previous state, if identical then the continuation monitored, do not send data to the telegon base station, this is a kind of pattern of economize on electricity, because detect the electric energy that data also need to consume battery in the described monitoring terminal by antenna transmission.Then will send to described telegon base station after the packing data as if inequality, proceed monitoring then; If after clicking " SOS " or the button that pushes for emergency on the menu, monitoring terminal sends emergency alarm information to the telegon base station.
The sensor of the monitoring terminal of the embodiment of the invention detects the change of the body movement state of monitored target with the time interval of setting, and for example sets 0.1 second to 1 second, 0.1 second to 10 seconds or the bigger time interval.Also can be set for the different periods in the different time intervals, for example morning, the activity change of monitored target be more frequent, and concerning the elderly, also is the bigger period of risk in one day, therefore can be set the less relatively time interval; Again noon for example, the activity change of monitored target is less relatively, and the relatively large time interval can be set.
Described processor is the core of described monitoring terminal, the detection signal data that it transmits described sensor, draw the condition change information of described monitored target through judgement after, by described antenna,, send described Surveillance center to through described telegon base station.
In order to judge accurately to the body movement state of monitored target, we are divided into eight kinds to the condition of monitored target (preferably the elderly) according to demand, be respectively stand, lie down, droping to the ground in the left side, drops to the ground in the right side, handstand, prostrate, jog and fall.With respect to the variation of condition, the magnitude of voltage of acceleration transducer on each is relevant with this stressing conditions.According to the normal wearing mode of described monitoring terminal, X-axis is a fore-and-aft direction, and Y-axis is a left and right directions, and the Z axle is an above-below direction.When three directions did not all stress, the magnitude of voltage on three directions was distributed between 1.2 volts to 2.1 volts.When only having a direction stressed, this situation for stand, lie down, droping to the ground in the left side, drops to the ground in the right side, stand upside down (emergency condition), prostrate, this direction this moment gravitate only.To stand is example, and Y, X-axis are not subjected to the effect of any power, so still between 1.2 volts to 1.7 volts, and the Z axle is subjected to the effect of gravity, and its direction is identical with the positive dirction of Z axle, and magnitude of voltage can increase to some extent, and its value zone of reasonableness is between 2.2 volts to 2.7 volts.When being in handstand (emergency condition) state, same Y, X-axis are not subjected to the effect of any power, still between 1.2 volts to 1.7 volts, and the Z axle is subjected to the effect of gravity, and its direction is identical with the negative direction of Z axle, and magnitude of voltage can reduce to some extent, and its value zone of reasonableness is between 0.6 volt to 1.1 volts.Other situation that a direction gravitate is only arranged and above-mentioned situation are similar.When monitored target is in when jogging state, through test, X, thus on the Y-axis because the scope of stressed effect change in voltage is little hardly, between 1.2 volts to 1.7 volts, and the mainly variation in 1.2 volts to 1.7 volts intervals of Z axle.When monitored target is fallen down (forward direction is fallen down), can produce the great changes of forward speed, be reflected on the acceleration transducer and be exactly the surge of X-axis magnitude of voltage and fall sharply, promptly less than 0.7, perhaps greater than 2.6 volts.Other can think a kind of " unknown state " not at the state of above-mentioned eight kinds of situation scopes.The body movement state of monitored target according to our approval, hold water through the above-mentioned as can be known analysis of actual test, drop to the ground with the right side and to be example, X-axis voltage is distributed in greater than 1.2 volts, in 1.7 volts, Y-axis voltage is distributed in greater than 0.6 volt, in 1.1 volts of intervals, the Z shaft voltage is distributed in greater than 1.2 volts, in 1.7 volts of intervals.
The described monitoring terminal of embodiments of the invention is classified to the body movement state of monitored target according to demand, and the situation of classification has multiple; For example: classification 1, be divided into eight kinds, be respectively stand, lie down, droping to the ground in the left side, drops to the ground in the right side, handstand, prostrate, jog and fall.Classification 2, be divided into upright (comprise stand and stand upside down), lie, crouch (lie on the left side and crouch in the right side), prostrate, run, fall etc. six kinds; Classification 3, also can simply be divided into two kinds: i.e. normal activity state (other states except that falling) and abnormality (falling).
For classification 1, the corresponding magnitude of voltage of each active state is classified, and finds corresponding every kind of state, and its magnitude of voltage distributes just like table 1.Utilize the voltage as a result in the table 1 to distribute,, can finish judgement the body movement state of monitored target by the judgement of three shaft voltage values that described sensor is gathered.Specifically can realize by sorter.
Table 1
And for classification 2, then the sorter of realizing by table 2 judges that the body movement state of monitored target gets final product.Can be for described classification 3, only need then judge that X-axis voltage is whether less than 0.7 or get final product greater than 2.6.In other words, for described classification 3, the sorter that is equivalent to realize by table 3 is judged the body movement state of monitored target.
Table 2
Table 3
| Condition | X-axis voltage (V) |
| Fall | X＜0.7 or X＞2.6 |
| Normal condition | 0.6＜X＜2.7 |
If through judging that monitored target is in the state of falling, this status signal transmits to Surveillance center, do corresponding processing by the alarm module of Surveillance center after, report to the police by the mode of its appointment and the number of appointment.Warning by monitored target triggers by warning button or menu option also transmits to described Surveillance center by described telegon base station, do corresponding processing by the alarm module of Surveillance center after, by the mode of its appointment and the number warning of appointment.
