Description

The storehouse integrated control system

Technical field

The utility model relates to a kind of control system, particularly be a kind of storehouse integrated control system.

Background technology

What the monitoring sensor of each storehouse all adopted in the bulk storage plant is magnetic switch, is installed in usually on the door or window of storehouse, and door and window is closed at ordinary times; Magnetic switch is a closure state; Supervisory circuit is in waiting status, and door and window will be opened when generation is stolen, and can't realize Long-distance Control.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of storehouse integrated control system is provided.

The utility model solves the technical scheme that its technical matters adopted: the storehouse integrated control system; Comprise alert detecting circuit and single chip machine controlling circuit; The output signal of said alert detecting circuit is sent to radio transmitter and RS485 communication interface circuit through single chip machine controlling circuit control; The output signal of said radio transmitter is sent to the wireless receiving warning circuit, said single chip machine controlling circuit also with the watchdog circuit bidirectional data communication.

Further; Said alert detecting circuit is made up of transistor VT1 and the relay K 1 that permanent magnet NS, magnetic switch JA and magnetic switch JA output terminal connect; Said magnetic switch JA is installed on the door or window that needs protection; Permanent magnet NS is installed on the door or window frame relative with magnetic switch JA, the base earth of said transistor VT1.

Further, said single chip machine controlling circuit adopts 8031 single-chip microcomputer IC1.

Further, the resistance R 4 that said radio transmitter is connected by 8031 single-chip microcomputer IC1 output terminals successively, transistor VT2 and FDD-5 transmitter module IC2 constitute, and said FDD-5 transmitter module IC2 is the modulated frequency electromagnetic waves of emission externally.

Further, said wireless receiving warning circuit is made up of LED 2 and the loudspeaker Y that JDD-5 module I C5 and output terminal thereof connect.

Further, said RS485 communication interface circuit is connected to the COM end of RS485 communication interface through SN75176 communication interface chip IC4.

Through adopting above-mentioned technical scheme, the beneficial effect of the utility model is: stolen when taking place, when door and window is opened; Magnetic switch breaks off, and supervisory circuit is started, and sends monitor signal; After single-chip microcomputer is judged, send alerting signal through radio transmitter to duty room, address, wireless receiving warning circuit main frame display alarm orientation; And link through RS485 system bus and other monitoring host computers, realize that control system is integrated.

Description of drawings

Fig. 1 is the frame assumption diagram of the utility model;

Fig. 2 is the circuit theory diagrams of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further to specify.

Like Fig. 1, shown in Figure 2; The storehouse integrated control system of the utility model; Comprise alert detecting circuit 1 and single chip machine controlling circuit 2, the output signal of said alert detecting circuit 1 is sent to radio transmitter 21 and RS485 communication interface circuit 23 through single chip machine controlling circuit 2 controls, and the output signal of said radio transmitter 21 is sent to wireless receiving warning circuit 22; Said single chip machine controlling circuit 2 also with watchdog circuit 3 bidirectional data communications, can reset to single chip machine controlling circuit 2.

Said alert detecting circuit 1 is made up of transistor VT1 and the relay K 1 that permanent magnet NS, magnetic switch JA and magnetic switch JA output terminal connect; Said magnetic switch JA is installed on the door or window that needs protection; Permanent magnet NS is installed on the door or window frame relative with magnetic switch JA, and when door and window was closed, magnetic switch JA was attracted to make inner contact closed by permanent magnet NS; Because the base stage of transistor VT1 is grounded; Making transistor VT1 is cut-off state, and the 39th pin I/O of 8031 single-chip microcomputer IC1 end also is low level state simultaneously, and 8031 single-chip microcomputer IC1 do not send control signal.

Door or window are opened when taking place to steal feelings, and permanent magnet NS and magnetic switch JA leave, and the QI inner contact is separated because of losing permanent magnet NS attraction; At this moment transistor VT1 conducting, relay K 1 energising adhesive at first makes the circuit self-locking with transistor VT1 short circuit through contact K1-1; At this moment no matter again door and window is closed again or opened, alarm condition all can not be removed, and at this moment the 39th pin I/O of 8031 single-chip microcomputer IC1 end is high level state; 8031 single-chip microcomputer IC1 send control signal, and the 2nd pin I/O mouth output high level signal by 8031 single-chip microcomputer IC1 makes transistor VT2 conducting through resistance R 4; Be input to the 2nd pin of FDD-5 transmitter module IC2, and deliver to its 3rd pin, i.e. modulation signal input end CP; High-frequency signal to emission is modulated, and antenna TX promptly externally launches modulated frequency electromagnetic waves.

Said wireless receiving warning circuit 22 is made up of LED 2 and the news Chinese percussion instrument Y that JDD-5 module I C5 and output terminal thereof connect; The 4th pin audio signal output end CPA of JDD-5 module I C5 directly drives common electrical dynamic formula loudspeaker Y sounding; Its 2nd pin data output end output high level makes LED 2 get electroluminescence simultaneously, and expression receives the alerting signal of extension set.

Form RS485 communication interface circuit 23 by the 1st, 2,3,4 pin of resistance R 6, SN75176 communication interface chip IC4 and the 10th, 11,27 pin of 8031 single-chip microcomputer IC1; RS485 communication interface circuit 23 is connected to the COM end of RS485 communication interface through SN75176 communication interface chip IC4; When 8031 single-chip microcomputer IC1 send alarm control signal; Transfer two buses to through the 6th, 7 of SN75176 communication interface chip IC4 and be connected to other monitoring host computer networkings; Uninterruptedly send data-signal by 8031 single-chip microcomputer IC1, realize the integrated networking of monitoring host computer to SN75176 communication interface chip IC4.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
