Below in conjunction with accompanying drawing, the technical solution adopted in the utility model and implementation done being described in further detail.
Core concept of the present utility model is: charged cable is adopted conventional detection mode, when detecting power down, start warning device; No electric wire cable is adopted the mode that detects resistance, and when resistance departed from normal structure, the interlink warning unit sent a warning message to the phone number that sets in advance with the GSM way of short messages, so that take action.
Please refer to Fig. 2, Fig. 2 is a system chart of the present utility model, as seen from the figure, cable theft-prevention device of the present utility model comprises: central controller 10, charged cable detecting unit 11, no electric wire cable detecting unit 12, GSM alarm unit 13, power module 14 and standby power supply 15.
It further comprises GSM alarm unit 11 the gsm communication interface is set, and mainly is to be used for when the lawless person steals cable, and GSM alarm unit 11 sends warning message by way of short messages; Charged cable detecting unit 11, in order to detecting the whether power down of charged cable, and with the central controller 10 of result's announcement; No electric wire cable detecting unit 12, in order to the two ends resistance of the cable that detects no electric wire cable, and, mainly judge whether to steal by resistance variations to the no electric wire cable two ends in the access device with the central controller of result's announcement, in case steal, then inform central controller 10.
The effect of central controller 10 is exactly the no electric wire cable resistance that detects access device when described charged cable detecting unit detects the charged cable power down of deploying troops on garrison duty or when described no electric wire cable detecting unit when changing, and described central controller starts described GSM alarm unit and sends warning information.
And central controller 10 is gone back connected storage, stores the contact details of the object that writes by software kit in advance or upgrade, need inform in the storer when taking place to report to the police, for example phone number.
Embodiment
Please refer to Fig. 3, principle of the present utility model realizes figure, connected status indicator lamp on the central processing unit, status indicator lamp can be LED lamp or other electricity-saving lamps, can be provided with voluntarily be used for display alarm information or the device whether start, whether be in the state of deploying troops on garrison duty, still cancelled the state of deploying troops on garrison duty.The switch of device then is used to control the switch of deploying troops on garrison duty of deploying troops on garrison duty and opening or cutting out by one.
Often do not adopt cut-out anti-theft device power supply earlier owing to do not send out molecule at the anti-theft device of prior art, the means of stealing again, the utility model is except being provided with and the AC power of peripheral hardware (adopting 220V power voltage supply commonly used), also be provided with standby power supply, even the peripheral hardware AC power is cut off like this, standby power supply equally can operate as normal, and standby power supply can adopt accumulator or the like.
Charged cable detecting unit 11 has comprised that further three charged cables insert passage, be respectively passage 1, passage 2 and passage 3, the cable of having switched on, for example C, B, A insert passage 1, passage 2 and passage 3 respectively by relay or K switch 1, K2, K3 respectively.
The GSM alarm unit has also connected the gsm communication interface, and as the passage of transmission alarming short message breath, the GSM technology is the most ripe communication technology, can guarantee higher acceptance and send message, the situation of avoiding note to lose.
No electric wire cable detecting unit is as the part that stresses of the present utility model, and it comprises that further three no electric wire cables insert passage, is respectively passage 4, passage 5, passage 6, respectively by a characteristic resistance and the not two ends of the cable of energising to be deployed troops on garrison duty.
Please refer to Fig. 4, Fig. 4 is the realization principle of no electric wire cable detecting unit, it comprises can select to stop size to select the measuring resistance of coupling at characteristic resistance, is provided with two identical resistance R 4 and R5 in the present embodiment, its objective is to preventing and wherein one damages the back cisco unity malfunction.
No electric wire cable detecting unit also comprises, one voltage follower circuit U2A, be used for measuring the voltage at resistance two ends this moment, and the voltage ratio of setting with the upper voltage limit comparator circuit U4A that is connected and lower voltage limit comparator circuit U4B, the signal that output is corresponding, when the voltage and the upper voltage limit of voltage follower circuit U2A output or the fiducial value of the voltage that rolls off the production line, the boundary that exceeds setting, then output terminal is exported corresponding signal to central controller, central controller judges that promptly cable is stolen, at this moment, the GSM alarm unit sends short message to the contact person.
When construction suspended, with the two strands access of no electric wire cable, at this moment, no electric wire cable detecting unit has the correspondent voltage signal and current signal produces, and this numerical value is predictable.
And the advantage of characteristic resistance is, its resistance is that every day is variable, its advantage is like this, be provided with characteristic resistance in the anti-theft device even there is the related personnel to know, wanting influences under the situation of central controller judgement by changing measuring resistance, also because of can't determining the current resistance of characteristic resistance, and can not implement its plan.
In sum, adopted the cable theft-prevention device of above technical characterictic, have following advantage and good effect than prior art: first, the utility model not only has charged cable measuring ability, also be provided with no electric wire cable detecting unit, adopt the mode that detects resistance, judge whether the cable that does not have electricity is stolen, and it is stolen to prevent not have the electric wire cable; The second, the utility model is provided with standby power supply in device, can prevent that the lawless person from destroying the power supply of cable theft-prevention device earlier, and the problem that causes anti-theft device to lose efficacy; Three, the utility model adopts general central controller, and electronic equipment commonly used, and is simple in structure, is easy to make; The 4th, the utility model adopts ripe gsm communication module, sends to a plurality of responsible officials' mobile phone simultaneously with short message mode, can guarantee in time to notify the responsible official so that in time take action when theft takes place, and avoids damage and increases the weight of.
More than disclosed only be preferred embodiment of the present utility model; but be not to be used for limiting itself; anyly have the knack of those skilled in the art under the situation of the utility model spirit, the equalization of being done changes and changes, and all should drop in the protection domain of the present utility model.
