Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, those of ordinary skill in the art obtained under not making creative work premise all other
Embodiment, broadly falls into the scope of protection of the invention.
As Figure 1-4, the invention provides a kind of emergence lighting lamp control system based on DC circuit, including storing
Battery and the emergency lighting main circuit of emergence lighting lamp composition, the accumulator terminal of main circuit connects signal modulating unit, main
The emergence lighting lamp end of circuit connects signal demodulation unit.
Accumulator provides DC220V direct current energy, when accumulator carries out emergent direct current supply, by signal modulating unit
Control instruction being made signal pulse be modulated accumulator output unidirectional current, accumulator output is formed containing modulated signal
Electric current, reaches both to transmit electric energy, sends again the purpose of information.
Modulated signal is usually the information that distinct pulse widths signal represents, as a example by RS232 data are transmitted, each byte is 8
Bit data, 42 bit data are 6 bytes.RS232 transmission to have 1 start bit, 8 bit data positions, 1 bit check position, 1 stopping
Position, say, that passing a byte and want the time of 11 used time, 6 bytes want 6*11=66 bit time.Every 1/9600 second, altogether
Use the 66/9600=0.006875 second.So, the pulse width of data message is the shortest, the power supply in light fixture or controller

The electric current of signal processed.
Signal demodulation unit, is arranged on signal receiving end (i.e. distribution electric box or exit signs or lighting end), will contain
The unidirectional current having modulated signal carries out signal demodulation, reaches the purpose of reception information.Because communication interface is different with requirement, straight
Stream signal of telecommunication pulses switch is the signal that COM1 is suitable for interface.
Signal demodulation unit includes the electric current for receiving containing modulated signal and modulated signal becomes low-voltage signal arteries and veins
The signal processing module of punching, for signal pulse is converted into data message, obtains control instruction, and sends control by I/O mouth
Signal processed carries out the demodulation control chip of emergence lighting lamp control, and for carrying out changing and to demodulation by accumulator electric energy
The demodulation power module that control chip is powered.
Wherein, signal processing module include current-limiting resistance R3 and the optocoupler G being serially connected, current-limiting resistance R3 and optocoupler G with
After dropping resistor R2 parallel connection, connect with dropping resistor R1.Electric current containing modulated signal passes through dropping resistor R1, dropping resistor R2
With current-limiting resistance R3, modulated signal is become low-voltage signal pulse, then delivers to demodulate control chip by light Rhizoma Nelumbinis G isolation.
Demodulation power module, signal processing module and demodulation control chip are all connected with main circuit, and signal processing module connects
Demodulation control chip, demodulation control chip connects demodulation power module.
The DC220V unidirectional current that accumulator is exported by demodulation power module is converted to 5V output, the work of demodulation control chip
Voltage is 5V, and signal processing module receives containing the electric current of modulated signal and modulated signal becomes low-voltage signal pulse exports
Demodulation control chip, signal pulse is converted into data message, obtains control instruction, and sent out by I/O mouth by demodulation control chip
Go out control signal and carry out emergence lighting lamp control.
The method of the control signal transmission of the present invention is completed by DC circuit, so, the communication mode of the present invention
Broadcast type transmission means can only be used.Control instruction sent out by i.e. main frame, receives from machine and performs instruction.Broadcasting instructions is as follows:
Main frame sends orders: [distribution electric box address] [command number 05] [byte number 4] [data 1] [data 2] [data 3]
[data 4] [check code]
Each byte illustrates:
[distribution electric box address]: emergency service is interval to be divided according to distribution electricity, it is simple to control and debugging.
05H: the command number writing digital quantity is fixed as 05
Byte number: send the number of data
[data 1] [data 2] [data 3] [data 4].Each data 8, every represents opening or closing of a light fixture
Close.Such as table 1:
Check code: 55H+ [distribution electric box address]+[command number 05]+[byte number 4]+[data 1]+[data 2]+[number
According to 3]+[data 4]
The present invention directly controls emergence lighting lamp by the DC circuit signal of telecommunication, can be as the weight of intelligent evacuation system
