Background technology
Fire-fighting distribution electric box is Intelligent fire-fighting emergency lighting and evacuation indication system, fire protection alarm system, fire-fighting fire-proof door
Important device in control system, in current system, system host, by communication board and distribution electric box and terminal communication, divides
Distribution box only has electric power distribution function, and such structure can bring the following two kinds shortcoming in the case of terminal quantity is a lot:
1) individual terminal occurs that communication failure not only can affect the communication in whole loop, and is unfavorable for malfunction elimination；
2) bus communication uses inquiry mode, and main frame and all of terminal room complete one query access needs long time,
Affect communication efficiency, cause under case of emergency, there will be indicating lamp change inconsistent.
The present invention is directed to disadvantage mentioned above, improve the networking mode of system, distribution electric box built in loops plate, circuit board monitors
Loop state, the status data of end of scan, preserve the message data of terminal status data, forwarding server and terminal in real time
Bag, server only just need to can obtain the data of terminal with distribution electric box communication.Whole system is equivalent to multi-CPU concurrent working, logical
Letter efficiency is greatly improved, and the quantity increasing circuit board can improve rapidly the integrated communication efficiency of system.It is independent of each other between loop,
Terminal fault only affects its loop, place, and fault location is fast.Circuit board can detect city's electricity condition and FAS dry contact letter
Number, issue emergent message, enable the terminals to be rapidly switched to emergency rating.Circuit board uses sluggishness to compare from lock technology, need not
Fuse wire is installed, when loop short circuit or loop current overload cause switching tube heating to exceed design temperature, is automatically switched off
Loop, and send warning message to server.Can release loop protection by server instruction or hand switch to lock, system is tieed up
Protect conveniently.
Summary of the invention
As shown in accompanying drawing 1,2, the panel of distribution electric installation is mainly by master control borad, circuit board, backboard 3 kinds.Every piece of loop
Plate can manage 2 road output loops, and master control borad, in addition to all functions comprising circuit board, also provides for communicating with system server
EBI, FAS interface, city's electro-detection interface.The distribution electricity master control borad of centralized Control dispersed power supply system also has battery charge and discharge
Electricity management interface, emergent switching interface.In addition to the two-way output loop that master control borad carries except needing management, it is necessary to possess management
The function of circuit board.
Master control borad has 2 kinds, and accompanying drawing 3 is centralized Control central power supply system distribution electricity master control borad functional block diagram, the type master
Control plate by MCU circuit unit, server communications circuit, status display circuit, state detection circuit, loop control circuit,
Loop bus interface circuit, 6 kinds of circuit units of backplane interface are constituted；Accompanying drawing 4 is main for centralized Control dispersed power supply system distribution electricity
Control plate functional block diagram, the type master control borad is by MCU circuit unit, server communications circuit, status display circuit, state inspection
Slowdown monitoring circuit, loop control circuit, loop bus interface circuit, battery charging management circuit, LCD drive interface circuit, should be eager
Change circuit, 10 kinds of circuit units of backplane interface are constituted.
Circuit board has 2 types, accompanying drawing 5 to be sweep type circuit board functional block diagram, and the type circuit board is by MCU circuit list
Unit, status display circuit, state detection circuit, loop control circuit, loop bus interface circuit, 6 kinds of circuit structures of backplane interface
Become, by hanging terminal status data under loop bus interface scans loop；Accompanying drawing 6 is reduced form circuit board functional block diagram, such
Type circuit board is by MCU circuit unit, status display circuit, state detection circuit, loop control circuit, 5 kinds of circuit of backplane interface
Constituting, do not have loop bus interface circuit, the terminal hung under this loop is directly managed by master control borad.
The Key Circuit that accompanying drawing 7 controls for output loop, circuit point sluggishness compares latching circuit and circuit switching controls electricity
Road two parts, the electric current of single-chip microcomputer sampling circuit and voltage data, control circuit switching.Sluggishness is used to compare latching circuit,
When loop short circuit, circuit overloads, circuit switching pipe temperature are too high, it is possible to automatic-closing circuit, it is to avoid circuit board damages.
Circuit management includes the reality of the terminal unit status data hung under loop output switch control, loop unblock, loop
Time the function such as collection.Circuit board preserves the last state data of all terminals, and master control borad can read from circuit board batch should
The last state data of all terminal units hung under loop.
Server can pass through master control borad, circuit board directly and terminal equipment in communication, and at this moment master control borad, circuit board play data
Bag forwarding effect.
Master control borad is consistent with the bus communication module interface on circuit board, module M1 as shown in accompanying drawing 10,11,12, M2,
The communication module of different communication modes can be selected according to system requirements.

Detailed description of the invention
As shown in Figure 7, resistance R18, R24, R43, R48, critesistor Rt2 provides gallon and the switch in loop 1
Pipe temperature sensing；Resistance R13, R15, R39, R49, critesistor Rt3 provides the gallon in loop 2 and switching tube temperature to visit
Survey；When loop current overrate or switching tube temperature overrate, latching circuit starts, and closes this loop, loop
Protection signal passes to single-chip microcomputer by OV1 and OV2 signal, and single-chip microcomputer reports server automatically.Loop unlocks passes through RESET
Signal completes, and RESET signal is controlled by Single-chip Controlling or the SR of master control borad, can pass through server instruction software solution
Lock, it is also possible to press unblock button scene and unlock.
Communication between master control borad and circuit board uses the communication of the terminal hung under I2C bus communication pattern, with loop to lead to
Cross bus communication module to carry out, as shown in accompanying drawing 10,11,12, during the free time, according to the terminal hung under the intermittent scanning set
Status data, refreshes the terminal's status information that this locality preserves.Master control borad can be read according to the cycle set and information filtering condition
Go bail for the terminal's status information existing on circuit board, transfer data to service by the bus communication module being connected to server
Device.Server can the actively terminal's status information on reading loop plate, it is also possible to directly and terminal communication, server and terminal
Between communication need to be forwarded by circuit board.
