Embodiment
Implement the city manhole cover of the utility model city manhole cover anti-theft circuit and follow the tracks of burglary-resisting system, as shown in Figure 1, comprise city manhole cover anti-theft circuit 1 of the present utility model, wireless communication networks, Alarm Server 2, and receiving terminal 3.
As shown in Figure 2, city manhole cover anti-theft circuit 1 of the present utility model comprises power supply 11, vibrations displacement transducer 12, testing circuit 13, CPU module 14, GPRS/GPS module 15, GPRS antenna 16 and gps antenna 17, and whole city manhole cover anti-theft circuit 1 sealing is arranged in the well lid.
Provide working power by power supply 11 for whole city manhole cover anti-theft circuit, power supply 11 can adopt rechargeable battery, also can adopt other power supplys; When adopting rechargeable battery as power supply, be provided with the interface J1 among the charging terminal 110(Fig. 3 that can be the rechargeable battery charging on the city manhole cover anti-theft circuit 1), the bottom of well lid has the through hole that two confessions arrange this charging terminal, this through hole is shut with marine glue at ordinary times, need excavate marine glue in the time of charging.
The top of well lid has for the through hole that GPRS antenna 16 and gps antenna 17 are set, and this through hole seals with fiberglass.
Gps antenna 17 is used for receiving the city manhole cover positional information from gps satellite 4;
During work, whether the well lid that detects the place by vibrations displacement transducer 12 is shifted, if displacement is arranged, then shake displacement transducer 12 output shift signals to testing circuit 13, send this shift signal to CPU module 14 by testing circuit 13, this shift signal is after CPU module 14 analyzing and processing, by CPU module 14 output alarm signals to GPRS/GPS module 15, the GPRS/GPS module 15 workers work of beginning, by the well lid positional information of control gps antenna 17 receptions from gps satellite 4, and control GPRS antenna 16 is sent to Alarm Server 2 with warning message with from the well lid positional information of gps satellite 4, Alarm Server 2 passes through background manage software, can detect the well lid of losing at once, track simultaneously the whereabouts of losing well lid, finally can locate offender's particular location, Alarm Server 2 is sent to receiving terminal 3 with this warning message and positional information, receiving terminal 3 can assist relevant departments to find offender's interests chain, thereby the offender is caught all in one draft.
In order to save the consumption of power supply, city manhole cover anti-theft circuit 1 of the present utility model has carried out Design of power saving, the Design of power saving of specifically awaiting orders and maintenance Design of power saving.
As shown in Figure 2, the output terminal of power supply 11 is connected with the hand switch S1 among the power switch 18(Fig. 3 that controls whole city manhole cover anti-theft circuit power break-make), the well lid bottom offers for the through hole that this power switch 18 is set.Well lid is in original state during being in place from dispatching from the factory to, and whole well lid can not work on power under this state.After well lid is in place, adopt specific purpose tool that power switch 18 is depressed connection by installation personnel, make the manhole cover anti-theft circuit of well lid inside enter armed state.Power switch 18 is irreversible disposable hand switches, and behind the connection circuit, the staff needs exposed through hole dead with the strengthened water proof rubber seal.
Under armed state, maximum characteristics are not power consumptions.Trigger the mechanism that powers on by testing circuit 13, do not power when power supply 11 is flat, only just power supply after well lid is moved away from original position, 11 life-spans of power supply just depend primarily on the nature velocity of discharge like this, can guarantee that after power supply this project demands is just satisfied in 12 hours work substantially.In case well lid is moved away from original position, vibrations displacement transducer 12 can detect, then the manhole cover anti-theft circuit works on power, reception is from the well lid positional information of gps satellite, adopt the GPRS connected mode to be connected to the Alarm Server 2 that administrative center possesses fixed ip address, send alerting signal and well lid positional information to Alarm Server 2, after Alarm Server 2 receives alerting signal and well lid positional information, manhole cover anti-theft circuit 1 enters alarm status, send the well lid positional information by the default time interval to Alarm Server 2, by Alarm Server 2 this well lid positional information is sent to again managerial personnel's mobile phone in the mode of note.
As shown in Figure 2, the power end of GPRS/GPS module 15 is connected to the output terminal of power supply 11 by electronic switch 19, one output terminal of CPU module 14 (the 39th pin) connects the so far trigger end of electronic switch 19, is controlled the break-make of the working power of GPRS/GPS modules 15 by electronic switch 19.As shown in Figure 3, electronic switch 19 comprises triode Q1 and relay K 1, the 39th pin (GSMPOWER) of CPU module 14 is connected to the base stage of triode Q1, when testing circuit 13 sends shift signal to CPU module 14, the 39th pin of CPU module 14 is exported trigger pip to the base stage of triode Q1, triode Q1 conducting, and relay K 1 must be established beginning work by cable, the normally opened contact of relay K 1 is connected the power end of GPRS/GPS module 15, and GPRS/GPS module 15 must be established beginning work by cable.
Under inspecting state, because well lid need be moved, after Alarm Server 2 also can receive alerting signal, through confirming as maintenance, then send note order by GPRS antenna 16 and GPRS/GPS module 15 to CPU module 14 by Alarm Server 2, enter inspecting state, CPU module 14 is not exported trigger pip to electronic switch 19, electronic switch 19 is off-state, and 15 outages of GPRS/GPS module are not worked.Predeterminable maintenance duration (such as 2 days) during inspecting state, under this state, only CPU module 14 is in the state of working on power, and after default maintenance duration arrived, CPU module 14 auto-breakings reentered armed state.The maximum characteristics of inspecting state are only CPU module 14 work, and power consumption is milliwatt level, very power saving.
