Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, alternating current on the voltage transformer and rechargeable battery are after the process power module manages, for the anti-theft device on the transformer provides power supply.Power supply is that the stolen sensor of transformer, case lid are opened monitoring device, voltage sensor, controller, radio communication device, bus-powered.The stolen sensor of transformer, case lid open that monitoring opening apparatus, voltage sensor detect respectively that transformer is shifted, the case lid of anti-theft monitoring device is opened, the alternating current on the voltage transformer is lost and passed to controller.Controller is imported according to these, judge the alerting signal kind, alerting signal is made up of the mark number and the warning kind of transformer, and by behind the center radio communication device on the radio communication device dispatching centre supervising device, is sent to computing machine by data extractor.Computing machine is crossed mark number and the warning kind of isolating transformer, by the mark number of the transformer in the database and the transformer mark number that receives are contrasted, find out the information such as position, managerial personnel of transformer, on display, show, perhaps pass through short message gateway, send the alarming short message breath to managerial personnel, perhaps, send alarm voice information, perhaps pass through network to managerial personnel by voice gateways, to other supervising devices, send warning message.
As Fig. 2, shown in Figure 3, an anti-theft bolt is installed on the case lid of transformer body.There is Push switch JP_BK1 lower end in the nut tube 2 of anti-theft bolt, spring 3 withstands between bolt 1 and the Push switch JP_BK1, the pin of Push switch JP_BK1 is connected on the two core socket J_IND by electric wire, behind the another one pin polyphone connection resistance RJ_BK, be connected on the two core socket J_IND through electric wire.The pin of two core socket J_IND is connected on the normal phase input end of operational amplifier U1_324A and the inverting input of operational amplifier U1_324D after holding circuit.Operational amplifier U1_324A connects the positive pole of diode DPH1, and operational amplifier U1_324D connects the positive pole of diode DPH2, and the negative pole of diode DPH1 links to each other with the negative pole of diode DPH2, enters into controller through the resistance R PH that contacts.The inverting input of operational amplifier U1_324A is imported 2/3 supply voltage.The normal phase input end of operational amplifier U1_324D is imported 1/3 supply voltage.Under the normal condition, bolt 1 gos deep into transformer case lid nut tube 2, and spring 3 is pressed to Push switch JP_BK1, and Push switch JP_BK1 switch is closed, and two pin short circuits of J_BK1 show low level.If robber's phase shifting transformer is turned on anti-theft bolt or sensing cable is broken, the power that spring 3 acts on the Push switch JP_BK1 disappears, and Push switch JP_BK1 disconnects, and 2 pin of Push switch JP_BK1 show the level identical with supply voltage.Will embody voltage fluctuation on the pin of two core socket J_IND, cause its voltage to be increased to more than 2/3 supply voltage, operational amplifier U1_324A will export high level to controller.The robber will go out voltage fluctuation with sense line or sensing cable short circuit on the pin of two core socket J_IND, cause its voltage to be reduced to below 1/3 supply voltage, and operational amplifier U1_324D will export high level to controller.Controller judges that according to the high level that receives displacement has taken place transformer, sends signal by radio communication device again, and signal is moved two parts information by the mark number of transformer and transformer and forms.After center radio communication device on the center monitoring device receives signal, be sent to computing machine by data extractor.Mark number and transformer that computing machine is isolated transformer are moved signal, by the mark number of the transformer in the database and the transformer mark number that receives are contrasted, find out the information such as position, managerial personnel of transformer, on display, show, perhaps pass through short message gateway, send the alarming short message breath to managerial personnel, perhaps, send alarm voice information, perhaps pass through network to managerial personnel by voice gateways, to other supervising devices, send warning message.
As shown in Figure 4, on the case lid of burglar alarm self, fix a snap switch.Snap switch can be closed along with opening of chamber door, closing of case lid and conducting.Snap switch is connected by electrical wiring to two core socket JP_BK2, contact then and be connected on the normal phase input end of operational amplifier U1_324C behind the connection resistance RJ_BK2, the inverting input of operational amplifier U1_324C is imported 1/2 supply voltage, and the anodal serial resistance RPH1 that the output of operational amplifier U1_324C connects diode DBK1 is linked into controller.Under the normal condition, the chamber door of anti-theft monitoring device is closed, snap switch conducting, operational amplifier U1_324C output low level.After chamber door is unlocked, the snap switch open circuit, operational amplifier U1_324C output high level is to controller.Controller judges that according to the high level that receives the case lid of anti-theft monitoring device is opened, and sends signal by radio communication device, and signal is made up of the mark number of transformer and transformer case lid two parts information that is opened.After center radio communication device on the center monitoring device receives signal, be sent to computing machine by data extractor.Computing machine is isolated the mark number of transformer and the transformer case lid signal that is opened, by the mark number of the transformer in the database and the transformer mark number that receives are contrasted, find out the information such as position, managerial personnel of transformer, on display, show, perhaps pass through short message gateway, send the alarming short message breath to managerial personnel, perhaps, send alarm voice information, perhaps pass through network to managerial personnel by voice gateways, to other supervising devices, send warning message.
As shown in Figure 5, voltage sensor is behind serial resistance R2 behind the AC power shunt capacitance C1, inserts LED light D_POWER and controller respectively.After AC power disappeared, LED light D_POWER is very fast to finish the power consumption in the electric capacity, and its both end voltage descends rapidly and puts below the 1V.Detect LED light D_POWER both end voltage by battery-driven controller and be lower than 1V, be judged as AC power and disappear, send signal by radio communication device, signal is made up of mark number and alternating current disappearance of signal two parts information of transformer.After center radio communication device on the center monitoring device receives signal, be sent to computing machine by data extractor.Computing machine is isolated the mark number and the alternating current disappearance of signal of transformer, by the mark number of the transformer in the database and the transformer mark number that receives are contrasted, find out the information such as position, managerial personnel of transformer, on display, show, perhaps pass through short message gateway, send the alarming short message breath to managerial personnel, perhaps, send alarm voice information, perhaps pass through network to managerial personnel by voice gateways, to other supervising devices, send warning message.
