Embodiment
As shown in the figure, the alarm probe is provided with microstructure heat distribution principle theft prevention monitoring microsensor, microcomputer processor MCU, radio communication circuit and GSM/GPRS module.Microsensor wherein adopts the biaxial MEMS acceleration transducer.Under the normal condition, probe was in dormant state, woke the detection data to the MEMS sensor up 1 time every 10 seconds, and wakeup time is 1 second.Probe was checked communication and power supply state of supply every 10 minutes, in case take place to send to the mobile phone that the user sets by GSM/GPRS unusually.The MEMS sensor has a reference axial direction, be called sensitive axis to.MEMS acceleration transducer induction acceleration of gravity its sensitive axis to component.Promptly when acceleration of gravity direction and its sensitive axis when becoming a certain angle of cut α, the MEMS acceleration transducer is exported the signal that the angle of cut therewith becomes cosine relation.The object of protection that probe adheres to is stirred or is moved, and will inevitably cause that two planes, sensitive axis place attitude take place change.In case the MEMS sensor records arbitrary axial angle changing greater than 3 degree, then probe will stop dormancy, calculate to continue transformation period.If continue transformation period less than 3 seconds, probe changes park mode over to, if greater than 3 seconds, probe will work on, start wireless sending module, send alerting signal to the alarm center master controller, simultaneously also can be to the mobile phone of user's setting by the telecommunications network remote transmission.
The alarm center master controller is often opened, and the processing of can setting up defences, withdraw a garrison all nodes can be preserved relevant information records in real time automatically.When the alarm center master controller receive corresponding establish the alerting signal of putting the address node after, this signal message is presented on the screen automatically, send sound and light alarm simultaneously, remind the related personnel to take corresponding measure fast.
Microsensor, amplification computing and mathematical operation integrated circuit and radio communication circuit all adopt little power consumption design and technology manufacturing, can organically join together and carry out device package, by the button cell powered operation.
Described heat distribution detecting sensor is a kind of acceleration (angular velocity) sensor, claims MEMS sometimes, can be a kind of outsourcing piece, and its principle of work is as follows:
Gas has density gradient in the acceleration direction, when thermal source is arranged, natural convection can take place in gas, heater strip (Heater) by semiconductor technology produced by micro processing heating usefulness on silicon, simultaneously heater strip along x, the y direction of principal axis is made temperature sensor (x+ respectively, x-, y+, y-), silicon etching below heater strip and the temperature sensor is formed a big cavity, (x+)-(x-) detect the acceleration of x direction, (y+)-(y-) detect the acceleration of y direction, then Chip Packaging is made into an acceleration transducer in the shell that cavity is arranged, in cavity, inflates.
When this sensor has the axial acceleration to x+, because heater strip heating, gas in the cavity can be set up a flow field, gas flows to x+ through heater strip from x-, the temperature T x-at the temperature sensor place of x-descends, and the temperature T x+ of x+ place rises, and (Tx+)-(Tx-) is proportional to acceleration magnitude, just can learn acceleration magnitude by converting.
