Upper computer software is realized based on Microsoft Visual 2005.The software section of condition monitoring device uses IAR Embeded Workbench 7.20B.
ZigBee telegon software program flow process is as shown in Figure 3.System begins to set up new network after the software and hardware initialization, each channel is carried out energy scan, selects an idle channel; After finding suitable channel, be new network identifier of network selecting, thereby set up new wireless network; And allowing old man's condition monitor to add, the binding of wait and old man's condition monitor is after completion is bound; Constantly whether monitoring has data to transmit from monitor; And the data that transmit are sent subroutine through serial ports send to PC, whether have the data that from PC transmit, if any then entering into the wireless transmission subroutine if detecting serial ports simultaneously.
The software flow pattern of old man's condition monitor is as shown in Figure 4: after the monitor initialization, and scanning channel, and join in the network of setting up the telegon base station; Obtain 16 network addresss, meeting display menu on the screen of monitor is after the user clicks " connection network "; Binding relationship is set up in monitor and telegon base station, and after the user clicked " transmission data ", monitor began to carry out the monitoring of condition; Every 3-axis acceleration data that read acceleration transducer MMA7260QT at a distance from 0.5 second; And carry out the AD conversion, judge to obtain old man's condition, and judge whether identical with previous state; If identical then the continuation monitored, if inequality then with sending to the telegon base station after the packing data; After the old man clicked " SOS " on the menu, monitor sent emergency alarm information to the telegon base station.
In order to judge accurately to old man's condition; We are divided into eight kinds according to demand to old man's condition; Be respectively stand, lie down, droping to the ground in the left side, drops to the ground in the right side, stand upside down, creep, jog and fall, and utilizes said system to gather a large amount of condition data, the corresponding magnitude of voltage of each body state is classified; Find corresponding every kind of state, its magnitude of voltage distributes just like table 2.
The magnitude of voltage of acceleration transducer on each is relevant with this stressing conditions.According to the normal wearing mode of terminal monitor, the X axle is a fore-and-aft direction, and the Y axle 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 axle do not receive the effect of any power, so still between 1.2 volts to 2.1 volts, and the Z axle receives the effect of gravity, and its direction is identical with the positive dirction of Z axle, so its value is between 2.2 volts to 2.7 volts.When being in handstand (emergency condition) state, same Y, X axle do not receive the effect of any power, and still between 1.2 volts to 2.1 volts, and the Z axle receives the effect of gravity, and its direction is identical with the negative direction of Z axle, so its value 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 people is in when jogging state, we are through test, X, so on the Y axle because the scope of stressed effect change in voltage is little hardly, between 1.2 volts to 2.1 volts, and the mainly variation in 1.2 volts to 2.1 volts intervals of Z axle.When monitored people falls 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 shaft voltage value and fall sharply, promptly less than 0.7, perhaps greater than 2.6 volts.At the state of above-mentioned eight kinds of situation scopes, we do not think " unknown state " for other.According to monitored people's the state of our approval, three shaft voltages when using MATLAB to obtain different conditions according to field data distribute (getting 100 groups of states), like Fig. 5, and Fig. 6; Fig. 7 and shown in Figure 8, as scheme to go up the DATA DISTRIBUTION situation and can know that above-mentioned analysis holds water, droping to the ground with the right side is example; The X shaft voltage is distributed in greater than 1.2 volts, and in 2.1 volts, the Y shaft 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 2.1 volts of intervals.
Table 2 body state relevant voltage value distributes
| Condition | X shaft voltage (V) | Y shaft voltage (V) | Z shaft voltage (V) |
| Stand | 1.2＜X＜1.7 | 1.2＜Y＜1.7 | 2.2＜Z＜2.7 |
| Lie down | 0.6＜X＜1.1 | 1.2＜X＜1.7 | 1.2＜X＜1.7 |
| Drop to the ground in the left side | 1.2＜X＜1.7 | 2.2＜Z＜2.7 | 1.2＜X＜1.7 |
| Drop to the ground in the right side | 1.2＜X＜1.7 | 0.6＜X＜1.1 | 1.2＜X＜1.7 |
| Stand upside down | 1.2＜X＜1.7 | 1.2＜X＜1.7 | 0.6＜X＜1.1 |
| Creep | 2.2＜Z＜2.7 | 1.2＜X＜1.7 | 1.2＜X＜1.7 |
| Jog | 1.2＜X＜1.7 | 1.2＜X＜1.7 | 1.2＜X＜1.7 |
| Fall | X＜0.7orX＞2.6 | -- | -- |
Utilize the result in the table 2,, can accomplish judgement old man's condition through judgement to three shaft voltage values.In the test of reality, obtained the discrimination of satisfaction based on the monitoring determination methods of said method.So that prolong the battery serviceable life of terminal monitor, after the microprocessor completion status monitoring only when the state of current states and preceding once monitoring is inconsistent to the telegon send state information.
Old man's condition monitoring system of the present invention is mainly used in family's indoor environment.Therefore in home environment, the communication distance that generally requires equipment uses in 100 meters for ease, and monitoring equipment should use wireless communications method.Because the equipment of monitoring wants long periods of wear on old man's health, then requires monitoring equipment to have portability, use the life-span of powered battery and battery longer, promptly at least more than 30 days.Because low in power consumption makes that wireless radiation power is lower, can not produce injury to human body.
