Description
Technical field
Fire alarm control unit technical field of the present invention, specially a kind of fire alarm system peculiar to vessel with Redundancy Design and its control
Method processed.
Background technology
This fire alarm control unit is mainly used in international shipping fire-fighting market, and it acts as detection ship fires, when it
When sending out fire, corresponding fire alarm information is provided, prompting related personnel puts out a fire in early days note that early detection fire behavior, in order to avoid
The disaster for causing bigger, fire damage, which is reduced to a minimum, important meaning, due to the safety etc. of some particular boats
Grade requirement is very high, proposes that fire alarm system will have Redundancy Design, when a fire alarm control unit cisco unity malfunction, it is ensured that
Entire fire alarm system remains to work normally.And existing fire alarm system peculiar to vessel is as shown in Figure 1, when fire alarm control unit cannot be just
Often when work, entire fire alarm system cannot also work normally.Generally there is the fire alarm system of Redundancy Design not prop up on the market
Loop checking installation is held, the requirement of fire alarm standard peculiar to vessel cannot be met.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of fire alarm system and its controlling party peculiar to vessel with Redundancy Design
Method can be always ensured that the normal work of entire fire alarm system, meet the requirement of fire alarm standard peculiar to vessel.
Its technical solution is such：A kind of fire alarm system peculiar to vessel with Redundancy Design comprising loop checking installation, the ring
Shape circuit is made of two buses, and fire detector is arranged in the bus, which is characterized in that every bus both ends difference
A fire alarm control unit is connected, is connected by communication line between two fire alarm control units, two fire
Calamity alarm controller is all connected with master controller.
A kind of fire alarm system control method peculiar to vessel with Redundancy Design, which is characterized in that when two buses work normally
And when the equal fault-free of two fire alarm control units, a fire alarm control unit is responsible for bus signaling and receives back value, separately
Short circuit makes two buses constitute loop checking installation inside one fire alarm control unit；When two buses work normally and a fire
When calamity alarm controller failure, another fire alarm control unit is responsible for bus signaling and receives back value；When two buses are equal
When having disconnection fault and the equal fault-free of two fire alarming and controllings, two fire alarm control units work respectively to bus signaling and
Receive back value；When any bar bus has disconnection fault and the equal fault-free of two fire alarm control units, two fire alarm controls
Device processed realizes time-sharing work by communication line, another fire alarm control when a fire alarm control unit controlling bus inspection
Device processed receives code.
After system and control method using the present invention, by one fire alarm control unit of additional designs, when wherein one
It can continue to ensure total system normal work when a failure, when two buses break down, moreover it is possible to ensure entire bus
Monitoring, two fire alarm control units can cooperate, be always ensured that the normal work of entire fire alarm system, met ship
With the requirement of fire alarm standard.
Description of the drawings
Fig. 1 is existing loop checking installation wiring schematic diagram；
Fig. 2 is loop checking installation wiring schematic diagram of the present invention；
Fig. 3 is that schematic diagram when disconnection fault occurs for two buses；
Fig. 4 is the fire alarm system typical case example peculiar to vessel for having Redundancy Design.
Specific implementation mode
See Fig. 2, a kind of fire alarm system peculiar to vessel with Redundancy Design comprising loop checking installation, loop checking installation is by two buses
It constitutes, arranges that fire detector, every bus both ends are separately connected a fire alarm control unit, i.e. in figure No. 1 in bus
Fire alarm control unit and No. 2 fire alarm control units, general to set No. 1 fire alarm control unit as master controller, No. 2 fire
Alarm controller is redundant manipulator, is connected by communication line between two fire alarm control units, two fire alarm controls
Device processed is all connected with master controller.
A kind of fire alarm system control method peculiar to vessel with Redundancy Design, when two buses work normally and two fire reports
When the equal fault-free of alert controller, a fire alarm control unit is responsible for bus signaling and receives back value, another fire alarm
Short circuit makes two buses constitute loop checking installation inside controller；When two buses work normally and a fire alarm control unit
When failure, another fire alarm control unit is responsible for bus signaling and receives back value；When two buses have disconnection fault and
When the equal fault-free of two fire alarming and controllings, two fire alarm control units work respectively to bus signaling and receive back value；When
When any bar bus has disconnection fault and two fire alarm control units equal fault-free, two fire alarm control units pass through communication
Circuit realizes time-sharing work, another fire alarm control unit receives code when a fire alarm control unit controlling bus inspection.
It is illustrated below according to Fig. 3 when two buses have the case where disconnection fault：
Draw above is existing, when there is broken string at two, the fire detector cisco unity malfunction on the right side of short-term,
And after Redundancy Design of the present invention as can be seen that same position is used according to following figure have and break at 2, the fire on the left side of breaking
Fire detector can be by No. 1 fire alarm control unit inspection on the left side, and the fire detector on the right can be by No. 2 fire alarm controls
Device inspection processed under equal conditions ensures the normal work of system, improves the reliability of system.
When only single line disconnects in breaking at 1 in bus, No. 1 fire alarm control unit and No. 2 are can be configured to
Fire alarm control unit time-sharing work, when No. 1 fire alarm control unit inspection, No. 2 fire alarm control units are set as receiving code state；
When No. 2 fire alarm control unit inspections, No. 1 machine is set as receiving code state；It in this way can be to avoid No. 1 fire alarm control unit and 2
The asynchronous influence to bus apparatus of number fire alarm control unit inspection simultaneously.Otherwise, as only disconnected T+, value is returned due to 2
Fire alarm control unit receives simultaneously, and time value can reduce half；When only break T- when, 2 fire alarm control units it is asynchronous
It can cause the detector in bus that cannot normally receive code.
Collaborative work flow between No. 1 machine and No. 2 machines is：
It needs to increase by one group of communication line between No. 1 fire alarm control unit and No. 2 fire alarm control units, when No. 1 fire
Calamity alarm controller is set as main, and when No. 2 fire alarm control units are set as slave, No. 1 fire alarm control unit is sent to No. 2 fire reports
Alert controller sends normal contact and warning message, to ensure synchronization of two machines in display.When No. 1 fire alarming and controlling
Device finds bus in the event of failure, sends out take over bus line command to No. 2 fire alarm control units, while bus is set as receipts pattern,
Surrender bus control right.At this point, No. 1 fire alarm control unit can only be looked by sending out querying command to No. 2 fire alarm control units
Ask the state of bus apparatus.After poll-final, No. 1 fire alarm control unit can send out withdrawal to No. 2 fire alarm control units
Bus control right order restores normal operating conditions.
When the connection between No. 1 fire alarm control unit and No. 2 fire alarm control units also disconnects, No. 1 fire report
Alert controller normal work, provides No. 2 machine communication failures.No. 2 fire alarm control units, which are in, receives pattern, by receiving code circuit
Whether there are DC24V and signaling waveform to judge whether No. 1 fire alarm control unit works normally, when determining no standard in bus
Voltage and more than after the regular hour, take over bus control right（No. 1 machine may not powered at this time, or constitute system annular
Respectively having at one at two up and down for circuit is broken entirely）.
