The specific embodiment
The present invention will be further described in detail below in conjunction with specific embodiment.
System forms as shown in Figure 1, is made up of wireless sensor network 1, sensor network monitoring host computer 2, vehicle GPS/GSM terminal 3, GSM antenna 4 and gps antenna 6.
Shown in Figure 2 is a complete sensors structure, and according to the monitoring target type, whole wireless sensor network 1 can be made up of the sensor of various different sensing types.Whole sensor is by sensing element 11, treater 12, and RF transceiver 13, the RF antenna forms 15, adopts the super low-power consumption design, carries supplying cell.When sensor senses object generation state changes, send signal to treater 12, treater 12 obtains current state thereupon, through screening, as after being judged as the time of day signal, handle back transmission RF transceiver 13 with soon carrying out the AES128 bit encryption for information about, will send to sensor network monitoring host computer 2 for information about by RF antenna 15.For car door, the monitoring of boot, sensor is installed in concealed location in the car.
Figure 3 shows that sensor network monitoring host computer 2, by user identity identification antenna 21, identification RF wireless communication interface 23, sensor network antenna 22, sensor network RF wireless communication interface 24, microprocessor 25, parameter configuration memory device 26 Hes, wired communication system 27 is formed.After host computer system recognizes a legal users identity arrival, the pattern of user identity identification control is set according to system, main frame sends the instruction of withdrawing a garrison automatically and (perhaps waits for the instruction of withdrawing a garrison, till the user sends the instruction of withdrawing a garrison), main frame sends the order of withdrawing a garrison to all the sensors immediately, so after sensor is received instruction, enter the low-power consumption wait state immediately, and no longer accept the action response of sensor.The user can select to be set to still system's automated manner of user's control, and setting can be passed through 2 approach:
1. directly be provided with by the change of 110 information service centers.
2. be provided with by vehicle-mounted user terminal requests 110 information service centers change.
After the user left, the host monitor system existed less than the legal users identity because of monitoring, and all the sensors in sensor network enters the state of setting up defences once more, and after this sensor will respond the state variation of perception, and in time report to main frame.
In addition, when being applied to certain position of special vehicle, can make sensor be operated in the state of setting up defences by being provided with, so that report the mode of operation of monitored object at any time always.
Main frame and terminal room realize by the wire communication mode, main frame by with the communicating by letter of terminal, send the report information of relevant main frame to 110 information service centers.Perhaps accept the various command that 110 information centers send to main frame by terminal.Each user identity identification by host acknowledgement after, by terminal, main frame reports that to 110 information centers when the user left, the status information reporting that main frame leaves and sets up defences about the user also can be received by same 110 information centers.
Remedied the blind spot of monitoring with present existing scheme contrast the present invention, it is simple to possess fitting operation, easy to maintenance, and crypticity is good, the characteristics of automatic intelligent.By with after present GPS/GSM maker cooperates, can all GPS/GSM terminals connect.In addition, because any information of system and 110 information service centers are realized interlock, therefore can obtain the timely processing of the police.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
