Abstract

The utility model relates to a monitoring system for public facilities. A conducting wire KN connected on a public facility, and a photoelectric coupling circuit U3 form an external trigger circuit; an output potential signal by the external trigger circuit is input to an FDD-5 emitting module U2; the FDD-5 emitting module can send modulation data signals to a JDD-5 receiving module U1; the output of an audio signal output terminal of the JDD-5 receiving moduel U1 drives a loudspeaker Y; simultaneously the output of a data output terminal controls an LED1 (light-emitting diode); the other branch of an output potential signal of the external trigger circuit is input to an I/O port of a single chip microcomputer IC1, is controlled by an internal program of the IC1 so as to be output by two branches: in the first branch, the IC1 controls a flasher driving circuit; in the other branch, serial data of the IC1 is transmitted to a GSM (global system for mobile communication) short message receiving module. The monitoring system can give an alarm by the trigger circuit in a wireless emission way; and after being received by a wireless mainframe, a wireless signal is processed by the single chip microcomputer, an indicating sign is emitted in situ so as to remind a user, and the messages are sent to a Municipal Administration Bureau by a GSM module.

Description

The communal facility supervisory system

Technical field

The utility model relates to the supervisory system field, particularly relates to a kind of communal facility supervisory system.

Background technology

Communal facility is through often being subjected to lawless person's theft and destruction as equipment such as urban operating mechanism well lid, road road facilities, cause damage and people's safety of walking to national wealth, and after the well lid of communal facility is stolen, often have personnel or vehicle to fall in the municipal well, cause injury to personnel.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of communal facility supervisory system is provided.

The technical scheme that the utility model adopted is such: the communal facility supervisory system, by the lead KN that is connected on the communal facility, photoelectricity coupled circuit U3 forms the external trigger circuit, the electric potential signal of its output is input to FDD-5 transmitter module U2, send modulated data signal by FDD-5 transmitter module U2 to JDD-5 receiver module U1, the audio signal output end output of JDD-5 receiver module U1 drives loudspeaker Y, simultaneously, its data output end output control LED 1, another road of output potential signal of external trigger circuit is input to the I/O port of single-chip microcomputer IC1, divide two-way output by the control of single-chip microcomputer IC1 internal processes, the first via is by single-chip microcomputer IC1 control flasher driving circuit, and the serial data transmission of another route single-chip microcomputer IC1 is to the GSM short message transceiving module.

Described single-chip microcomputer IC1 output connects 5054 watchdog circuit IC3, and single-chip microcomputer IC1 internal processes is recovered automatically.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this system, is received after after the single-chip microcomputer processing, Warning Mark is sent at the scene by wireless host after wireless transmit is reported to the police by trigger circuit, reminds people is taken care, and reports and submits information by gsm module to municipal administration office.

Description of drawings

Fig. 1 is circuit theory diagrams of the present utility model.

Embodiment

Further specify the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, the communal facility supervisory system, form the external trigger circuit by lead KN, the photoelectricity coupled circuit U3, resistance R 2, the R3 that are connected on the well lid, when lead KN is up broken well lid by stealer, photoelectricity coupled circuit U3 converts cut-off state to by conducting state, the output high potential signal is input to FDD-5 transmitter module U2 the 2nd pin through resistance R 3, and is sent to the 3rd pin CP modulation signal input end of FDD-5 transmitter module U2, and the high-frequency signal of emission is modulated.Form wireless receiving circuit by JDD-5 receiver module U1, loudspeaker Y, resistance R 4, LED 1, antenna TX etc., FDD-5 transmitter module U2 connects antenna JDD-5 receiver module U1 is launched modulated frequency electromagnetic waves, the 4th pin CPA audio signal output end of JDD-5 receiver module U1 directly drives common electrical dynamic formula loudspeaker Y sounding, simultaneously, its the 2nd pin data output end output high level makes LED 1 get electroluminescence, and expression receives the alerting signal of extension set.The 4th pin I/O port that its another road is input to single-chip microcomputer IC1 is high level state, divide two-way output through the control of single-chip microcomputer IC1 internal processes, first via output is by the 34th pin output high level signal of single-chip microcomputer IC1, through resistance R 9 current limlitings, triode Q1 enters conducting state, relay J adhesive, switch J-1 closure, it is luminous to promote flasher QM, reminds the walking at night to take care; The second tunnel output by the 35th, 36,37, the 6 pin serial data transmission of single-chip microcomputer IC1 to GSM short message transceiving module IC2, drive GSM short message transceiving module IC2 and send SMS alarm information, pre-set the transmission short message content by mobile phone, " * * motor-pumped well lid is opened by force, please notes inspection." the 3rd, 7,8,39, the 38 pin output of described single-chip microcomputer IC1 connects the 1st, 2,7,5,6 pin of 5054 watchdog circuit IC3; form reset circuit by resistance R 1, capacitor C 1; make the 3rd pin and 5054 watchdog circuit IC2 the 7th pin preset of single-chip microcomputer IC1; single-chip microcomputer IC1 internal processes is recovered automatically, prevent that its internal processes is in the endless loop state.

More than show and described ultimate principle of the present utility model and principal character and advantage thereof; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
