Composition, single-chip microcomputer model is AT89S52, is responsible for reception, decoding and control to bypass instruction, output interface be respectively P0.0 extremely
P0.7, P1.0 are to P1.7, P2.0 to P2.7.
Fig. 4 is the theory diagram of bypass circuit part of the present invention, and Fig. 5 is four bidirectional analogs of bypass circuit part of the present invention
The theory diagram of switch.As shown in figure 5, from the point of view of economy and ease for use, bypass circuit part of the invention is two-way using four
Analog switch, the model CD4066 of four bilateral analog switch, is mainly used as the multiplexing of analog or digital signal, CD4066
It is made up of four separate two-way switch, each corresponding control interface of switch；With reference to shown in Fig. 4 and Fig. 5, bypass electricity
By taking one of defence area as an example, bypass circuit part includes four bilateral analog switch U2A, triode Q1, triode for road part
Q2, bypass resistance R4, the 13rd pin and single-chip microcomputer of four bilateral analog switch U2A control interface, i.e. four bilateral analog switch U2A
Output interface connection, four bilateral analog switch U2A input interface, i.e. four bilateral analog switch U2A the 1st pin pass through line end
Resistance RX is connected with the output interface of monitoring probe, and the R2 in figure is piezo-resistance, for lightning protection, four bilateral analog switch
U2A output interface, i.e. the 2nd pin of four bilateral analog switch U2A are connected with bypass resistance R4 and alarm host machine respectively, bypass electricity
The resistance R4 other end is connected with triode Q2 colelctor electrode, the triode Q2 base stage colelctor electrode and resistance with triode Q1 respectively
R3 connections, the resistance R3 other end are connected with positive 5V power supplys, and triode Q1 base stage is exported with single-chip microcomputer respectively by resistance R5
Interface and four bilateral analog switch U2A the 13rd pin connect.
Bypass resistance R4 resistance is depending on the resistance of line end resistance, and line end resistance is a resistance element, directly
The inside of monitoring probe is welded on, each monitoring probe can connect a line end resistance, monitor the quantity of probe according to report
Depending on alert system requirements；The bypass resistance R4 of present invention resistance is equal to the resistance of line end resistance, because after bypass, equal to cut-out
Monitoring probe and line end resistance, so needing to refill a line end resistance, bypass resistance R4 is to play a part of to replace line end resistance.
The single-chip microcomputer that control circuit part uses can realize 1 to 32 for the every single-chip microcomputer with 32 road output interfaces
The control output on road.According to actual requirement of engineering, every single-chip microcomputer at most 16 roadside road circuit parts of control, because with bypass
The number N of circuit part quantity increase, the size of circuit board can also increase (because the quantity of electronic component can increase), must
So make the cabinet of mounting circuit boards can also increase (because cabinet not only needs mounting circuit boards to also need to install other power supplys or light
The equipment such as terminal), but situation of actually multiple defence area expansion boards installed in same place is more rare, is all generally
1-2 block expansion boards, so selected N is less than or equal to 16.
Also include host computer, host computer is connected with control circuit part；Defence area keeper selectes defence area by host computer, so
Manual or timing setting of deploying troops on garrison duty or withdraw a garrison is carried out to each defence area afterwards, host computer is electric to control by the information transfer that user sets
Road part, the single-chip microcomputer of control circuit part are deployed troops on garrison duty or withdrawn a garrison to each defence area setting according to the information that user sets, when
Timing to or need change cloth, disarming state when, single-chip microcomputer transmits instructions to bypass circuit part, bypass circuit part
After the instruction for identifying single-chip microcomputer, command information is output to output par, c, corresponding cloth is carried out to specified defence area so as to realize
Prevent or withdraw a garrison；Then the single-chip microcomputer of control circuit part is by the feedback of status of bypass circuit part to host computer, and host computer is to scheme
The mode of shape is shown.The effect of host computer be for safety-protection system keeper provide graphical interfaces, receive bypass operation, hair
The bypass message in specified defence area is sent, automatically deploying troop is carried out to defence area according to preset time and withdrawn a garrison, while is graphically shown
Show the information of deploying troops on garrison duty and withdraw a garrison in defence area.
Below by taking the first section of embodiment as an example, illustrate the workflow of the defence area bypath system of warning system of the present invention
Journey：
When the defence area of monitoring probe needs normally to be deployed troops on garrison duty, AT89S52 single board computer receives the control letter of host computer
Number, the output interface P0.0 output high level of AT89S52 single board computer, triode Q1 conductings, triode Q2 cut-offs, bypass resistance R4
Do not work；Meanwhile model CD4066 four bilateral analog switch U2A the 13rd pin is because of input high level, analog switch
Conducting, monitoring probe is set to be turned on by line end resistance RX with the connection of defence area expansion board.
When the defence area of monitoring probe needs bypass, AT89S52 single board computer receives the bypass instruction of host computer, single-chip microcomputer
AT89S52 output interface P0.0 output low levels, triode Q1 cut-offs, triode Q2 conductings, bypass resistance R4 and ground connect,
Bypass resistance R4 is accessed equivalent to this defence area, the line end resistance of the monitoring probe of the present embodiment is 10k Ω, so bypass electricity
The resistance for hindering R4 is 10k Ω.Meanwhile four bilateral analog switch U2A the 13rd pin because input low level, analog switch is in height
Resistance state, disconnect the connection of monitoring probe and defence area expansion board.
Fig. 6 is the example schematic of the present invention.As shown in fig. 6, below by taking certain the exhibition of cultural relics Room as an example, in the show room Room
It is respectively T1 to T5 to be provided with 5 infrared microwave dual technology detectors, and 4 infrared emission detections are then provided with the exterior wall of show room
Device is respectively T6 to T9, and this 9 detectors are connected by 2 pieces of defence area expansion boards with same alarm host machine respectively, this implementation
The bypath system of example need to only set 9 bypass circuit parts, and 9 bypass circuit parts are separately positioned on 9 detectors and 2
Between the expansion board of block defence area, the control terminal of 9 bypass circuit parts is connected with the control circuit part of bypass circuit part respectively.
When exhibition room is carried out, when stream of people's quantity is big and crowded, instruction can be sent by host computer makes part probe in bypass
State, T1 is in bypass condition to T5 detectors, T6 to T9 is in Normal Alarm state；In the exhibition room exhibition of closing or people's fluxion
When measuring rare, then instruction sent by host computer, T1 to T9 is completely in Normal Alarm state, so as to ensure effective monitoring
On the premise of, effectively mitigate total line pressure, avoid that data blocking and systemic breakdown accident occurs.System can also be real according to defence area
Border situation, the function of being bypassed using host computer time set, is such as opened or closed bypass functionality automatically in some periods.
In a word, the present invention realizes from hardware bypasses to the output signal of detector, can be according to the reality in defence area
Border situation just uploads to effective warning message, and invalid warning message does not upload completely；And can realize manually or
Timing automatic bypass operation, the pressure of bus is significantly reduced, solve the problems, such as data blocking.
