Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model structure is as shown in figure 1, including photoswitch, there are photoswitch two input interfaces and two outputs to connect
Mouth totally four optical fiber interfaces, wherein, the output interface of the first equipment is connected to the first input interface of photoswitch, the second equipment
Input interface is connected to the first output interface of photoswitch, and the second input that the output interface of the second equipment is connected to photoswitch connects
Mouthful, the input interface of the 3rd equipment is connected to the second output interface of photoswitch.
Work route：
By the presence of protection equipment II：A→B→C→D→E→F→G→H
By the bypass condition of protection equipment II：A→B→G→H
Presence and bypass condition switching control condition：
A. power-off bypass
When system equipment power supply, which breaks down, to power（Supply voltage is less than+7V）, light bypass apparatus realize moment from
It is dynamic to be switched to bypass condition, it is ensured that equipment continues to communicate below, when power is restored（Supply voltage+7V~+15V）, bypass apparatus
Presence is switched to, whole system is continued to run with.
B. low and high level control bypass
Control panel has two I/O ports to be connected on light bypass apparatus, and one is low and high level, and one is ground；When control panel is normal
During work, I/O port output high level（3.3V）To light bypass apparatus, light bypass apparatus is in presence；When control panel breaks down
（Such as cpu fault, FPGA failures）, I/O port output low level（<0.7V）To light bypass apparatus, light bypass apparatus automatically switches to bypass
State, it is ensured that equipment continues to communicate below.
