Description
Technical field:
The present invention relates to a kind of remote facility autoalarm, more specifically, relate to a kind of theft preventing method and device of field facility.This alarm can be made alarm response to theft, the destruction of remote equipment.
Background technology:
At present, the safeguard protection of home market remote facility and supervision are the problems that enterprise, unit pay attention to.Especially theft, destructive insident have more related to production safety and loss of assets.Therefore, the remote facility warning device also arises at the historic moment, and many anti-theft product occurred, and the principle of employing mainly is: use sense line to twine protection equipment, use vibration detector protection equipment, use infrared protection equipment etc.
The relative merits of several anti-theft protections:
1. sense line twines: when broken ring of equipment or pilferage, the short circuit of sense line elder generation triggers reports to the police, and shortcoming is that the sense line short circuit then loses protection, warning effect, and sensitivity is lower;
2. vibration detector: when vibration equipment, trigger and report to the police, shortcoming is that sensitivity is difficult for regulating the rate of false alarm height;
3. infrared acquisition: when infrared sensor is caught less than equipment, trigger and report to the police, shortcoming is that influenced by luminous environment bigger, the rate of false alarm height.
Summary of the invention:
The objective of the invention is to improve the sensitivity of remote facility autoalarm, reduce rate of false alarm simultaneously, reduce user's false alarm operational processes in the maximum magnitude.
The theft preventing method of field facility of the present invention, comprise a method that triggers alarm with the AVR Single Chip Microcomputer (SCM) program, described alarm is connected with an electronic memory call wire, it is characterized in that: described AVR Single Chip Microcomputer (SCM) program whenever obtains the mean value of fixed number of times time arithmetic mean value of sampled value calculating as current electronic memory call wire, arithmetic mean value of current electronic memory call wire mean value calculation of simultaneously same number of times, and as new call wire correlative value, on single-chip microcomputer, preestablish simultaneously the domain of walker of the correlative value of call wire sampled value, whether in the domain of walker of a preceding correlative value, judge whether trigger alarm by once correlative value after the contrast, described alarm has a signaling conversion circuit, when described alarm was triggered, signaling conversion circuit written-out program control signal triggers the unlimited communication module of GSM (GPRS) can send warning information to predefined receiving equipment such as mobile phone etc.
The theft preventing method of field facility of the present invention is characterized in that the fiducial value that the mean value after the detection of fixed number of times detects as fixed number of times next, and this fiducial value is as the correlative value of current time simultaneously.
The theft preventing method of field facility of the present invention is characterized in that sampled value is the current value or the magnitude of voltage of current electronic memory call wire.
The present invention also aims to provide the device of the theft preventing method of realizing field facility, described this device is made up of an electronic memory call wire and alarm and cable, wherein, described alarm mainly is made up of shell, power supply high voltage plate, low voltage control plate, accumulator, microphone, loudspeaker, described electronic memory call wire, power supply high voltage plate, accumulator, microphone, loudspeaker are connected with the low voltage control plate by the 2PIN connector, and the power supply high voltage plate is by the terminal stube cable.
Further, when described power supply high voltage plate cuts off the power supply, give the power supply of mortgage control panel by accumulator.
Further, the resistance value of every meter of described electronic memory call wire is the sense line of 50 Ω-200 Ω.
Further, be equipped with the unlimited communication module of AVR single-chip microcomputer and GSM (GPRS) on the described low voltage control plate, embed C programmer on the described AVR single-chip microcomputer.
What further, described AVR single-chip microcomputer adopted is the MEGA16/MEGA32AVR single-chip microcomputer that ATMEL produces.
The anti-theft device of field facility of the present invention, when abrupt action such as the electronic memory call wire is cut off, short circuit, connection in series-parallel, electronic memory call wire sampled value changes suddenly when making mean value not in the preceding correlative value of once measuring, promptly surpass or be lower than the domain of walker value of correlative value permission, trigger burglar alarm, synchronous signal change-over circuit written-out program control signal triggers the unlimited communication module of GSM/GPRS can send alarm message to predefined phone number.
Remote facility autoalarm of the present invention is characterised in that when the remote facility autoalarm runs into the situations such as sensor values fluctuation that strong-electromagnetic field instantaneous interference or temperature cause, the sampling computational algorithm of program can shield interference, the correlative value scope will change with the fluctuation of temperature, thereby reduces rate of false alarm.
Description of drawings
The structural drawing of Fig. 1 field facility anti-theft device critical piece (except the shell)
Fig. 2 field facility anti-theft device resistance detection special technology synoptic diagram.
Embodiment:
As shown in Figure 1, this figure is the structural drawing according to the remote equipment autoalarm critical piece (except the shell) of the present invention's design, mainly by a power supply high voltage plate, low voltage control plate and accumulator, microphone, loudspeaker, parts such as electronic memory call wire are formed, wherein the low voltage control plate is a critical piece, AVR single-chip microcomputer and GSM/GPRS wireless communication module have been comprised, described power supply high voltage plate, accumulator, microphone, loudspeaker, the electronic memory call wire all is connected on the low voltage control plate by the 2PIN connector, the work that cooperatively interacts of each parts realizes the theft warning function.
Embodiment is: at first with the electronic memory call wire of remote equipment autoalarm tightly on controlled object, and alarm is fixed on the position of adaptation and starts alarm apparatus; Single Chip Microcomputer (SCM) program can sampling obtains electronic memory call wire voltage value to A/D earlier, and quantize, compare, store, whenever obtain 20 sampled values and calculate an arithmetic mean value as current electronic memory call wire mean value, arithmetic mean value of per 20 current electronic memory call wire mean value calculation of while, and as new call wire correlative value.The domain of walker that preestablishes simultaneously the correlative value of call wire sampled value on single-chip microcomputer is the preceding correlative value ratio that fluctuates.
When abrupt action such as the electronic memory call wire is cut off, short circuit, connection in series-parallel, electronic memory call wire sampled value changes suddenly when making mean value not in the preceding correlative value of once measuring, promptly surpass or be lower than the domain of walker value of correlative value permission, trigger burglar alarm this moment, the unlimited communication module of GSM (GPRS) can send alarm message to predefined phone number simultaneously.
As Fig. 2 is field facility anti-theft device resistance detection special technology synoptic diagram, and R3, R4 are two resistance wires, in actual applications these two resistance wires is formed a cable, and tightly on controlled object, makes and must must destroy cable by mobile controlled object.As long as the burglar cuts off any resistance wire like this, will produce warning, if two disconnect simultaneously and also can produce warning, and, because the burglar does not also know the resistance of resistance, if the burglar wants to replace by a simple resistance in parallel, at this moment because the change of overall resistance also can start warning.
